GOLD RESOURCE CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2018

(Unaudited)

1. Basis of Preparation of Financial Statements

The interim Condensed Consolidated Financial Statements (“interim statements”) of Gold Resource Corporation and its subsidiaries (collectively, the “Company”) are unaudited and have been prepared in accordance with the rules of the Securities and Exchange Commission for interim statements. Certain information and footnote disclosures required by United States Generally Accepted Accounting Principles (“U.S. GAAP”) have been condensed or omitted although the Company believes that the disclosures included are adequate to make the information presented not misleading. In the opinion of management, all adjustments (including normal recurring adjustments) and disclosures necessary for a fair presentation of these interim statements have been included. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. These interim statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2017 included in the Company’s annual report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements.  Unless otherwise noted, there have been no material changes to the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s annual report on Form 10-K.

2. Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Accounting Standards Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued guidance that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU was further amended in August 2015, March 2016, April 2016, May 2016 and December 2016 by ASU No. 2015-14, No. 2016-08, No. 2016-10, No. 2016-12 and No. 2016-20, respectively.  The guidance provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  On January 1, 2018, the Company adopted the new accounting guidance to all contracts using the retrospective approach.    The adoption of this new guidance did not result in any changes to previously reported revenue amounts.  Please see Note 3 for more information.

Recently Issued Accounting Pronouncements

Accounting Standards Update No. 2016-02 Leases (Topic 842). In February 2016, the FASB issued a new standard regarding leases. Lessees will be required to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and a lease liability. Public business entities are required to adopt the new leasing standard for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For calendar year-end public companies, this means an adoption date of January 1, 2019. Early adoption is permitted. The Company anticipates adopting the new guidance effective January 1, 2019.

The Company has begun its assessment of the new guidance and the impact it will have on the Consolidated Financial Statements and disclosures, and expects to complete its analysis in 2018. Management is still completing its assessment of the impacts; however, based on preliminary findings, the Company expects that the majority of its identified leases will be required to be reported on the Consolidated Balance Sheets.  Based on the preliminary assessment, the Company expects there will be minimal impacts to the Consolidated Statements of Operations. The Company expects to have an update to the impacts of the standard in the third quarter of 2018.

3. Revenue

The Company derives its revenue from the sale of doré and concentrate.  The following table presents the Company’s net sales disaggregated by source:

	Three months ended March 31,
	2018		2017
	(in thousands)
Doré sales, net
Gold	$	1,909	$	1,627
Silver		297		21
Less: Treatment and refining charges		(25)		(17)
Total doré sales, net		2,181		1,631
Concentrate sales
Gold		5,541		7,086
Silver		6,081		7,288
Copper		2,380		1,310
Lead		3,847		1,938
Zinc		13,384		6,056
Less: Treatment and refining charges		(1,834)		(1,508)
Total concentrate sales, net		29,399		22,170
Realized/unrealized embedded derivative, net		571		535
Total sales, net	$	32,151	$	24,336

Doré Revenue

Doré sales are recognized upon the satisfaction of performance obligations, which occurs when control of the doré transfers to the customer.  Transfer of control occurs once the customer takes possession of the doré.  Doré sales are recorded using quoted metal prices, net of treatment and refining charges.

Concentrates Revenue

Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of treatment and refining charges, at the time of delivery to the customer as that is when performance obligations are satisfied and control of the product is transferred to the customer.   Until final settlement occurs, adjustments to the provisional sales prices are made to take into account the mark-to-market changes based on the forward prices of metals for the estimated month of settlement.  The changes in price between the provisional sales price and final sales price are considered an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the quoted metal prices at the time of delivery. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through revenue each period prior to final settlement. Changes in the prices of metals that the Company sells, as quoted on the London Bullion Market, between the delivery and final settlement dates will result in adjustments to revenues related to sales of concentrate previously recorded upon delivery. Sales are recorded net of charges for treatment, refining, smelting losses and other charges negotiated with the buyer. These charges are estimated upon delivery of concentrates based on contractual terms and adjusted to reflect actual charges at final settlement. Historically, actual charges have not varied materially from the Company’s initial estimates.

4. Gold and Silver Rounds/Bullion

The Company periodically purchases gold and silver bullion on the open market for investment purposes and to use in its dividend exchange program under which shareholders may exchange their cash dividends for minted gold and silver rounds. During the three months ended March 31, 2018 and 2017, the Company purchased nil ounces and 64.3 ounces, respectively, of gold bullion.

At March 31, 2018 and December 31, 2017, the Company’s holdings of rounds/bullion, using quoted market prices, consisted of the following:

	2018					2017
	Ounces	Per Ounce		Amount		Ounces	Per Ounce		Amount
				(in thousands)					(in thousands)
Gold	1,904	$	1,324	$	2,521	1,905	$	1,291	$	2,459
Silver	80,160	$	16.28		1,305	80,224	$	16.87		1,353
Total holdings				$	3,826				$	3,812

5. Inventories, net

At March 31, 2018 and December 31, 2017, inventories, net consisted of the following:  

	2018		2017
	(in thousands)
Stockpiles - underground mine	$	1,612	$	1,450
Stockpiles - open pit mine		82		101
Concentrates and doré		2,609		2,367
Materials and supplies (1)		8,617		7,718
Total	$	12,920	$	11,636

(1) Net of reserve for obsolescence of $734 and $743, respectively.

6. Income Taxes

The Company recorded income tax expense of $3.6 million and $2.9 million for the three months ended March 31, 2018 and 2017, respectively.  The Company’s annualized effective rate differs from the U.S. corporate rate of 21% primarily due to differences in statutory rates for income and mining taxes in Mexico.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which significantly revised the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system, imposing a one-time tax on foreign unremitted earnings and setting limitations on deductibility of certain costs, among other things.  The Company has not revised any of the 2017 provisional estimates under SAB No. 118 and ASU No 2018-05.  The Company continues to gather information and is awaiting further guidance from the IRS, SEC and FASB on the Tax Act.

Mexico requires a 10% withholding tax on dividends to both residents and non-resident shareholders on all post-2013 earnings.  Dividends from earnings generated prior to 2014 were exempted from the new dividend withholding tax.  The Company plans to distribute post-2013 earnings from Mexico beginning in 2018.  According to the existing US – Mexico tax treaty, the dividend withholding tax between these countries is limited to 5% if certain requirements are met.  Based on the Company’s review of these requirements, it estimates it will pay a 5% withholding tax on dividends received from Mexico in 2018.  The impact of the planned annual dividends for 2018 is reflected in the estimated annual effective tax rate.

In 2015, the Mexican government approved a 2016 Federal Revenue Act that provides tax incentives, including tax credits on Mexican Excise Duty (a.k.a., IEPS), for the acquisition of combustible fossil fuels to be used in productive processes. The Company’s Mexican operations utilize a significant amount of diesel fuel for power generation that

7

qualifies for such tax credits. These tax credits can be applied against income taxes payable, as well as other income tax withholdings during the year. In the three months ended March 31, 2018 and 2017, the Company recorded $1.1 million and $0.7 million, respectively, of fuel tax credits to offset production costs and such credits were applied against the income tax payable. 

As of March 31, 2018, the Company believes that it has no liability for uncertain tax positions.

7. Prepaid Expenses and Other Current Assets

At March 31, 2018 and December 31, 2017, prepaid expenses and other current assets consisted of the following:

	2018		2017

15. Stock-Based Compensation

During 2016, the Company replaced its Amended and Restated Stock Option and Stock Grant Plan (the “Prior Plan”) with the Gold Resource Corporation 2016 Equity Incentive Plan (the “Incentive Plan”).  The Incentive Plan allows for the issuance of up to five million shares of common stock in the form of incentive and non-qualified stock options, stock appreciation rights, RSUs, stock grants, stock units, performance shares, performance share units and performance cash.  Additionally, pursuant to the terms of the Incentive Plan, any award outstanding under the Prior Plan that is terminated, expired, forfeited, or canceled for any reason, will be available for grant under the Incentive Plan.

During the three months ended March 31, 2018, a total of 14,964 restricted stock units (“RSUs”) vested and shares were issued with an intrinsic and a fair value of $0.1 million.

During the three months ended March 31, 2018, stock options to purchase an aggregate of 1,000,000 shares of the Company’s common stock were exercised at exercise prices ranging from $4.37 to $5.00 per share.  Of that amount, 945,000 of the options were exercised on a net exercise basis, resulting in 244,345 shares being delivered.  The remaining 55,000 options were exercised for cash.

Stock-based compensation expense for stock options and RSUs is as follows:

	Three months ended March 31,
	2018		2017
	(in thousands)
Stock options	$	174	$	53
Restricted stock units		62		147

17. Net Income per Common Share

Basic earnings per common share is calculated based on the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated based on the assumption that stock options outstanding, which have an exercise price less than the average market price of the Company’s common shares during the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds obtained from the exercise were used to purchase common shares at the average market price during the period. All the Company’s restricted stock units are considered to be dilutive.

The effect of the Company’s dilutive securities is calculated using the treasury stock method and only those instruments that result in a reduction in net income per common share are included in the calculation. Options to purchase 3.1 million and 2.8 million shares of common stock at weighted average exercise prices of $11.41 and $9.77 were outstanding at March 31, 2018 and 2017, respectively, but were not included in the computation of diluted weighted average common shares outstanding, as the exercise price of the options exceeded the average price of the Company’s common stock during those periods, and therefore are anti-dilutive.

Basic and diluted net income per common share is calculated as follows:

	Three months ended March 31,
	2018		2017
Net income (in thousands)	$	5,457	$	4,376
Basic weighted average shares of common stock outstanding		57,120,077		56,796,751
Dilutive effect of share-based awards		791,222		1,194,882
Diluted weighted average common shares outstanding		57,911,299		57,991,633
Net income per share:
Basic	$	0.10	$	0.08
Diluted	$	0.09	$	0.08

18. Fair Value Measurement

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

12

As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth certain of the Company’s assets measured at fair value by level within the fair value hierarchy as of March 31, 2018 and December 31, 2017:  

	2018		2017		Input Hierarchy Level
	(in thousands)
Cash and cash equivalents:
Bank deposits	$	28,617	$	22,390	Level 1
Gold and silver rounds/bullion		3,826		3,812	Level 1
Accounts receivable:
Receivables from provisional concentrate sales		1,642		2,884	Level 2
	$	34,085	$	29,086

Cash and cash equivalents consist primarily of cash deposits and are valued at cost, which approximates fair value. Gold and silver rounds/bullion consist of precious metals used for investment purposes and in the dividend program which are valued using quoted market prices. Please see Note 4 for additional information. The Company determined that it was not practicable to estimate the fair value of its non-current investment in equity securities of $0.2 million and as such, it is reported at cost. There have been no events or changes in circumstances that may have a significant adverse effect on the investment.

Trade accounts receivable include amounts due to the Company for deliveries of concentrates and doré sold to customers. Concentrate sales contracts provide for provisional pricing as specified in such contracts. These sales contain an embedded derivative related to the provisional pricing mechanism which is bifurcated and accounted for as a derivative. At the end of each reporting period, the Company records an adjustment to sales to reflect the mark-to-market of outstanding provisional invoices based on the forward price curve. Because these provisionally priced sales have not yet settled as of the reporting date, the mark-to-market adjustment related to these invoices is included in accounts receivable as of each reporting date.  At March 31, 2018 and December 31, 2017, the Company had an unrealized loss of $0.03 million and an unrealized gain of $0.4 million, respectively, included in its accounts receivable on the accompanying Condensed Consolidated Balance Sheets.  Please see Note 14 for additional information.

Gains and losses related to changes in the fair value of these financial instruments were included in the Company’s consolidated statements of operations as shown in the following table:

	Three months ended March 31,

ITEM 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion summarizes the results of operations of Gold Resource Corporation and its subsidiaries (“we”, “our”, or “us”) for the three months ended March 31, 2018 and compares those results to the three months ended March 31, 2017.  It also analyzes our financial condition at March 31, 2018 and compares it to our financial condition at December 31, 2017. This discussion should be read in conjunction with the management’s discussion and analysis and the audited consolidated financial statements and footnotes for the year ended December 31, 2017 contained in our annual report on Form 10-K for the year ended December 31, 2017.

The discussion also presents certain financial measures that are not prepared in accordance with U.S. Generally Accepted Accounting Principles (“non-GAAP”) but which are important to management in its evaluation of our operating results and are used by management to compare our performance with what we perceive to be peer group mining companies, and are relied on as part of management’s decision-making process. Management believes these measures may also be important to investors in evaluating our performance. For a detailed description of each of the non-GAAP financial measures, please see the discussion below under Non-GAAP Measures.

See Forward-Looking Statements at the end of this Item 2 for important information regarding statements contained herein.

Overview

We are a mining company which pursues gold and silver projects that are expected to have both low operating costs and high returns on capital. We are presently focused on mineral production from the Aguila and Alta Gracia Projects within our Oaxaca Mining Unit. Our processing facilities at the Aguila Project produce doré and concentrates primarily from ore mined from the Arista underground mine, which contains precious metals of gold and silver and base metals of copper, lead and zinc, and from the Mirador underground mine, which contains gold and silver. Additionally, we are focused on exploration and advancement of our Nevada properties, including our Isabella Pearl Project which is in advanced stages of engineering and permitting.

Precious metal gold equivalent, used periodically throughout this discussion, is determined by taking gold ounces produced or sold, plus silver ounces produced or sold converted to precious metal gold equivalent ounces using the gold to silver average price ratio for the period. The gold and silver average prices used to determine the gold to silver average price ratio are the actual metal prices realized from sales of our gold and silver. Please see the section titled Non-GAAP Measures below for additional information concerning cash cost per ounce measures.

Highlights

Highlights for the first quarter of 2018 are summarized below and discussed further in our Results of Operations:

· Our cash balance increased to $28.6 million at March 31, 2018;

· We purchased the County Line property, furthering our land holdings in our Nevada Mining Unit;

· Our net income was $5.5 million or $0.10 per share;

· Total cash cost after by-product credits per precious metal gold equivalent ounce sold was a negative $316;

· Total all-in sustaining cost per precious metal gold equivalent ounce sold was $347.

Exploration and Development Activities

Exploration activities are performed on our portfolio of exploration properties in Oaxaca, Mexico and Nevada, U.S.A. All of the properties that make up our Oaxaca Mining Unit are located along what is known as the San Jose structural corridor in the Sierra Madre, which runs north 70 degrees west. Our properties comprise 55 kilometers of this structural corridor which spans three historic mining districts in Oaxaca. Our Nevada Mining Unit properties are in the Walker Lane Mineral Belt which is known for its significant and high-grade gold-silver production from current and historic mines.  Our Nevada properties are in close proximity to each other for potential equipment and manpower synergies of future operations.

Oaxaca Mining Unit, Mexico

The Aguila Project: Our mine activities during the first quarter of 2018 continued to focus on development and ore extraction from the Arista and Switchback vein systems. Exploration activities during the quarter mainly focused on underground exploration drilling at the Switchback vein system in the Arista Mine. The Switchback drilling program continued to target further expansion and delineation of the multiple high-grade parallel veins for reserve definition, expansion and mine plan optimization. The Switchback vein system remains open on strike and vertical extent. Also during the first quarter, we completed underground drilling on a new high-grade ore-shoot in the Arista vein system. Eight underground diamond drill holes totaling 3,154 meters were completed at the Aguila Project during the first quarter of 2018.

Alta Gracia property: Mirador Mine development and access to previously identified mineralization continued during the first quarter of 2018. Exploration activities during the quarter included surface and underground geological mapping and sampling along with detailed topographic surveying in the historic mining areas at Alta Gracia. This new information along with previous drilling results will be used as a guide for follow-up drilling planned during 2018.

Margaritas property: During the first quarter of 2018, surface and underground geological mapping and sampling along with detailed topographic surveying was conducted in the historic mining areas at Margaritas. Interpretation of results from this work along with previous surface drilling, geological mapping and rock chip channel sampling will be used for preparation of a future surface drilling program.

Nevada Mining Unit, U.S.A.

Isabella Pearl Project: Project permitting continued during the first quarter of 2018. Our goal remains to advance the project into production at the earliest possible date, subject to permit timing, funding, and construction timeline. We are targeting the production of gold doré from a potential open pit heap leach operation. We have received Nevada Department of Environmental Protection approvals and are now awaiting the Bureau of Land Management regulatory permit approvals to move the project forward. Exploration work during the quarter included integration of historical data, especially to the northeast and northwest, which are adjacent to and along strike of the Isabella Pearl deposit currently targeted for development.

On April 19, 2018, we announced the completion of our initial report on the reserve estimate and feasibility study for the Isabella Pearl Project with an effective date of December 31, 2017, confirming the existence of proven and probable reserves as defined in Industry Guide 7 promulgated by the U.S. Securities and Exchange Commission (“SEC”).

16

As of December 31, 2017, our estimate of Proven and Probable (“P&P”) reserves was: 

Description	Tonnes	Gold g/t	Silver g/t	Gold Ounces	Silver Ounces
Isabella Pearl Project
Proven	590,500	5.44	37	103,300	697,900
Probable	2,104,000	1.32	6	89,300	431,200
Isabella Pearl Project Total	2,694,500	2.22	13	192,600	1,129,100

Notes to the Isabella Pearl P&P reserves:

1. Metal prices used for P&P reserves were $1,222 per ounce of gold and $16.62 per ounce of silver.  These prices reflect the three-year trailing average prices for gold and silver.

2. The quantities of material within the designed pits were calculated using a cutoff grade of 0.61 Au g/t for Crushed ore and 0.38 Au g/t for Run-of-Mine (ROM) ore.

3. Mining, processing, energy, administrative and smelting/refining costs were based on first quarter 2018 cost estimates used for the Isabella Pearl Project feasibility study.

4. Metallurgical gold recovery assumptions used were 81% for Crushed ore and 60% for ROM ore.  These recoveries reflect predicted average recoveries from metallurgical test programs

5. Silver is an economic mineral of interest but only a minor amount will be recovered.  Silver recoveries were not considered in the Isabella Pearl Project feasibility study.

6. P&P reserves are diluted and factored for expected mining recovery.

7. Figures in tables are rounded to reflect estimate precision and small differences generated by rounding are not material to estimates

Our P&P Reserve estimates were prepared by our technical staff under the direction of Barry Devlin, Vice President of Exploration.  Mr. Devlin holds a Bachelor of Science degree with honors in Geology, 1981, and a Masters in Geology, 1987, from the University of British Columbia, Vancouver, Canada. He is also a Professional Geologist registered with the Association of Professional Engineers and Geoscientists of British Columbia.

For a description of the key assumptions, parameters and methods used to estimate the Isabella Pearl P&P Reserves included in this report, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing or other factors, please see the Isabella Pearl reserves and feasibility report to be posted on our website (http://www.goldresourcecorp.com) in the near future.

Mina Gold property: During the first quarter of 2018, we prepared a surface drilling program targeting expansion to depth of known surface high-grade gold mineralization on our patented claims.  This reverse circulation drilling program commenced in April. 

Gold Mesa property: Reverse circulation drilling resumed at Gold Mesa during the first quarter of 2018. The program continued to target expansion of several areas of surface and near surface high-grade gold mineralization discovered during previous drilling programs.  During the quarter, thirty-eight holes totaling 2,518 meters were drilled on the Gold Mesa property. 

East Camp Douglas property:  We continued to review historical geological, exploration and mining data on the East Camp Douglas property during the first quarter of 2018. Exploration activities included examinations and surveying of the historic mine workings in the Cerro Duro mine area and historic drill collars.

County Line property:On March 12, 2018, we purchased the County Line property for cash of $0.3 million.  The property is located in close proximity to our other Nevada properties in central Nevada’s Walker Lane Mineral Belt in Mineral and Nye counties. In addition, we staked additional unpatented claims around the property to strengthen the land position and exploration potential. The total land package is 2,320 acres consisting of 116 unpatented lode mining claims and one unpatented placer mining claim. Review of historical geological, exploration and mining data along with initial field investigations are currently underway at the County Line property targeting a future initial surface drilling program.

Results of Operations

The following table summarizes our results of operations:

	Three months ended March 31,
	2018		2017
	(in thousands)
Sales, net	$	32,151	$	24,336
Mine gross profit		12,920		10,416
General and administrative expenses		2,354		1,812
Exploration expenses		1,185		822
Other expense		278		464
Income before income taxes		9,103		7,318
Provision for income taxes		3,646		2,942
Net income	$	5,457	$	4,376

Sales, net

Net sales of $32.2 million for the first quarter of 2018 increased by $7.8 million, or 32%, when compared to the same period in 2017. The increase was primarily a result of higher volume and prices for base metals and higher sales prices for gold.  For the three months ended March 31, 2018, average realized prices for gold and base metals increased from the same period in 2017 as follows: gold by 10% to $1,342 per ounce, copper by 22% to $7,156 per tonne, lead by 9% to $2,573 per tonne, and zinc by 34% to $3,805 per tonne.  During the same period, the average metal price for silver decreased by 4% from 2017 prices.

Please see the Sales Statistics table below for additional information regarding our mineral sales statistics.

Production

For the first quarter of 2018, gold and silver production were 6,647 ounces and 425,884 ounces, respectively, as compared to 6,747 and 427,890 ounces over the same period in 2017.  During the same period, gold and silver grades for the Arista Mine decreased by 29% and 43%, respectively, from the same period in 2017, as a function of the particular areas of the mine we are extracting, specifically mining the deepest mineralization at the Switchback vein system.  In the future, we plan to mine upwards towards higher-grade areas of the vein system.  Offsetting the lower precious metal grades and recoveries was higher mill throughput, which contributed to a higher overall base metal production. 

Ore grades in the Arista Mine vary depending on the mining locations and mining techniques being utilized during a particular quarter or quarters.  Our gold recoveries in the first quarter of 2018 at the Arista Mine decreased by 11% as a result of a change in the metallurgical response of the mill feed in the quarter. The different response is related in part to Switchback ore characteristics. We are actively working on a response to this change and expect to return to previous gold recovery levels in the future.

Aguila Open Pit production during the first quarter of 2018 as compared to 2017 was reduced to take advantage of higher ore production capability from the Arista Mine.

Mirador Mine production from our Alta Gracia project was primarily development ore. We expect to see higher grades and recoveries when we begin production stoping.

During the quarter ended March 31, 2018, we processed a total 1,636 ore tonnes per day compared to 1,206 ore tonnes processed per day for the same period in 2017, representing an increase of 36%.  During the quarter, the agitated leach plant was ore feed from both the Aguila Open Pit and the Mirador Mine representing 6% of combined milled tonnage. Gold and silver production in the form of doré represented an additional 5% and 6% of gold and silver production, respectively.  Going forward, we expect to optimize the production and milling schedules between the Aguila Open Pit and Mirador Mine.

18

On a precious metal gold equivalent basis, our mill production totaled 11,909 ounces for the first three months of 2018, compared to 12,837 ounces for the same period of 2017. Please see the Production Statistics table below for additional information regarding our mineral production and sales statistics.

During the three months ended March 31, 2018, we sold 5,563 gold ounces and 381,366 silver ounces at a total cash credit per ounce, after by-product credits, of $316 as a result of strong base metal sales during the quarter. Please see Non-GAAP Measures below for additional information concerning the cash cost per ounce measures.

(1) Average metal prices realized vary from the market metal prices due to final settlement adjustments from our provisional invoices when they are settled. Our average metal prices realized will therefore differ from the market average metal prices in most cases.

(2) For a reconciliation of this non-GAAP measure to total mine cost of sales, which is the most comparable U.S. GAAP measure, please see Non-GAAP Measures.  

(3) Total cash (credit) cost was significantly affected by unusually high base metals sales as compared to precious metals sales.

Other Financial Results

Mine gross profit. For the three months ended March 31, 2018, mine gross profit increased by $2.5 million or 24%, compared to the same period in 2017. The increase was due to increased metals sales as a result of higher realized gold and base metal prices and a significant increase in base metal production.

General and administrative expenses. For the quarter ended March 31, 2018, general and administrative expenses totaled $2.4 million as compared to $1.8 million for the same period in 2017.  The increase of $0.6 million was primarily due to higher legal and accounting fees.

Exploration expenses. For the three months ended March 31, 2018, exploration expenses totaled $1.2 million as compared to $0.8 million for the three months ended March 31, 2017.  The $0.4 million increase was primarily the result of increased spending at our Isabella Pearl property and drilling at our Gold Mesa property.

Other expense.  For the three months ended March 31, 2018, we recorded other expense of $0.3 million as compared to other expense of $0.5 million for the three months ended March 31, 2017. The $0.2 million change in three months ended March 31, 2018 was a result of a decrease in foreign currency losses as the Mexican peso weakened in 2018 as compared to 2017.  Please see Note 16 to the Condensed Consolidated Financial Statements for additional information.

Provision for income taxes.  For the three months ended March 31, 2018, our provision for income taxes was $3.6 million as compared to $2.9 million for the same period in 2017. The increase of $0.7 million for the first quarter of

20

2018 is commensurate with our increase in income for period as compared to the same period in 2017. Please seeNote 6 to the Condensed Consolidated Financial Statements for additional information.

Non-GAAP Measures

Throughout this report, we have provided information prepared or calculated according to U.S. GAAP and have referenced some non-GAAP performance measures which we believe will assist with understanding the performance of our business. These measures are based on precious metal gold equivalent ounces sold and include cash cost before by-product credits per ounce, total cash cost (credit) after by-product credits per ounce, total all-in sustaining cost per ounce (“AISC”) and all-in cost per ounce (“AIC”). Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies. Accordingly, these measures should not be considered in isolation, or as a substitute for, measures of performance prepared in accordance with U.S. GAAP. These non-GAAP measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP, nor are they indicative of future performance.

Total cash cost, after by-product credits, is a measure developed by the Gold Institute in an effort to provide a uniform standard for comparison purposes. The guidance was first issued in 1996 and revised in November 1999. AISC and AIC are calculated based on guidance from the World Gold Council issued in June 2013.

Total cash cost before by-product credits includes all direct and indirect production costs related to our production of metals (including mining, milling and other plant facility costs, smelter treatment and refining charges, royalties, and site general and administrative costs) less stock-based compensation allocated to production costs plus treatment and refining costs.

Total cash cost (credit) after by-product credits includes total cash cost before by-product credits less by-product credits, or revenues earned from base metals.

AISC includes total cash cost (credit) after by-product credits plus other costs related to sustaining production, including sustaining allocated general and administrative expenses and sustaining capital expenditures. We determined sustaining capital expenditures as those capital expenditures that are necessary to maintain current production and execute the current mine plan.

AIC includes all-in sustaining costs plus non-sustaining capital expenditures and exploration expense related to the Oaxaca Mining Unit.  Exploration and capital expenditures to develop new properties outside our Oaxaca Mining Unit are excluded from this calculation.

Cash cost before by-product credits per ounce, total cash cost (credit) after by-product credits per ounce, AISC and AIC are calculated by dividing the relevant costs, as determined using the cost elements noted above, by precious metal gold equivalent ounces sold for the periods presented.

Liquidity and Capital Resources

As of March 31, 2018, we had working capital of $29.8 million, consisting of current assets of $48.7 million and current liabilities of $18.9 million. This represents an increase of $2.3 million from the working capital balance of $27.5 million at December 31, 2017. Our working capital balance fluctuates as we use cash to fund our operations, financing and investing activities, including exploration, mine development, income taxes and shareholder dividends.

Cash and cash equivalents increased $6.2 million to $28.6 million during the first three months of 2018.

Net cash provided by operating activities of $14.0 million increased $5.0 million for the first three months of 2018 compared to the same period in 2017, primarily due to an increase in net income and changes in operating assets and liabilities.

Net cash used in investing activities of $7.3 million increased $1.2 million for the first three months of 2018 compared to the same period in 2017 due to increased mine development in our Arista Mine and the purchase of the County Line property in our Nevada Mining Unit.

Net cash used in financing activities remained consistent at $0.3 million for both the three months ended March 31, 2018 and 2017.

We believe that our liquidity and capital resources are adequate to fund our operations and corporate activities for the foreseeable future.  In the event that construction on our Isabella Pearl Project commences in 2018, we would evaluate the use of cash, equity financing, debt financing, or a combination thereof to fund the capital requirements.  There can be no assurances that such financing will be available when or if needed upon acceptable terms, or at all.

To provide financial flexibility, on April 3, 2018, we entered into an At The Market Offering Agreement (the “ATM Agreement”) with an investment banking firm (“Agent”) pursuant to which the Agent will act as our sales agent with respect to the offer and sale from time to time of our shares having an aggregate gross sales price of up to $75.0 million (the “Shares”).  The ATM Agreement will remain in full force and effect until the earlier of April 3, 2021, or the date that the ATM Agreement is terminated in accordance with the terms therein. No sales have been made pursuant to the ATM Agreement as of April 30, 2018.

Forward-Looking Statements

This report contains or incorporates by reference “forward-looking statements,” as that term is used in federal securities laws, about our financial condition, results of operations and business. These statements include, among others: 

· statements about our future exploration, permitting, and plans for development of our properties;

· statements concerning the benefits that we expect will result from our business activities and certain transactions that we contemplate or have completed, such as receipt of proceeds, decreased expenses and avoided expenses and expenditures; and

· statements of our expectations, beliefs, future plans and strategies, our targets, exploration activities, anticipated developments and other matters that are not historical facts.

These statements may be made expressly in this document or may be incorporated by reference from other documents that we will file with the SEC. You can find many of these statements by looking for words such as “believes,” “expects,” “targets,” “anticipates,” “estimates,” or similar expressions used in this report or incorporated by reference in this report.

These forward-looking statements are subject to numerous assumptions, risks and uncertainties that may cause our actual results to be materially different from any future results expressed or implied in those statements. Because the statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied. We caution you not to put undue reliance on these statements, which speak only as of the date of this report. Further, the information contained in this document or incorporated herein by reference is a statement of our present intention and is based on present facts and assumptions, which may change at any time and without notice, based on changes in such facts or assumptions.

24

Risk Factors Impacting Forward-Looking Statements

The important factors that could prevent us from achieving our stated goals and objectives include, but are not limited to, those set forth in other reports we have filed with the SEC, including our Form 10-K for the year ended December 31, 2017, and the following:

· Changes in the worldwide price for gold and/or silver;

· Volatility in the equities markets;

· Adverse results from our exploration or production efforts;

· Producing at rates lower than those targeted;

· Political and regulatory risks;

· Weather conditions, including unusually heavy rains;

· Earthquakes or other unforeseen ground movements impacting mining or processing;

· Failure to meet our revenue or profit goals or operating budget;

· Decline in demand for our common stock;

· Downward revisions in securities analysts’ estimates or changes in general market conditions;

· Technological innovations by competitors or in competing technologies;

· Investor perception of our industry or our prospects;

· Lawsuits;

· Actions by government central banks; and

· General economic trends.

We undertake no responsibility or obligation to update publicly these forward-looking statements, but may do so in the future in written or oral statements. Investors should take note of any future statements made by us or on our behalf.

ITEM 3: Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risks includes, but is not limited to, the following risks: changes in commodity prices, foreign currency exchange rates, provisional sales contract risks, changes in interest rates, and equity price risks. We do not use derivative financial instruments as part of an overall strategy to manage market risk; however, we may consider such arrangements in the future as we evaluate our business and financial strategy.

Commodity Price Risk

The results of our operations depend in large part upon the market prices of gold, silver, and base metal prices of copper, lead and zinc. Gold and silver prices fluctuate widely and are affected by numerous factors beyond our control. The level of interest rates, the rate of inflation, the stability of exchange rates, the world supply of and demand for gold, silver and other metals, among other factors, can all cause significant fluctuations in commodity prices. Such external economic factors are in turn influenced by changes in international investment patterns, monetary systems and political developments. The price of gold and silver has fluctuated widely in recent years, and future price declines could cause a mineral project to become uneconomic, thereby having a material adverse effect on our business and financial condition. We have not entered into derivative contracts to protect the selling price for gold or silver. We may in the future more actively manage our exposure through derivative contracts or other commodity price risk management programs, although we have no intention of doing so in the near-term.

25

In addition to adversely affecting our reserve estimates, results of operations and/or our financial condition, declining gold and silver prices could require a reassessment of the feasibility of a project. Even if a project is ultimately determined to be economically viable, the need to conduct such a reassessment may cause delays in the implementation of a project.

Foreign Currency Risk

Foreign currency exchange rate fluctuations can increase or decrease our costs to the extent we pay costs in currencies other than the U.S. dollar. We are primarily impacted by Mexican peso rate changes relative to the U.S. Dollar, as we incur some costs in Mexican peso. When the value of the peso rises in relation to the U.S. Dollar, some of our costs in Mexico may increase, thus affecting our operating results. Alternatively, when the value of the peso drops in relation to the US Dollar, peso-denominated costs in Mexico will decrease in U.S. Dollar terms.  These fluctuations do not impact our revenues since we sell our metals in U.S. dollars. Future fluctuations may give rise to foreign currency exposure, which may affect our financial results.

We have not utilized market-risk sensitive instruments to manage our exposure to foreign currency exchange rates but may in the future actively manage our exposure to foreign currency exchange rate risk.  

Provisional Sales Contract Risk

We enter into concentrate sales contracts which, in general, provide for a provisional payment based upon provisional assays and prices. The provisionally priced sales contracts contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates determined at the quoted metal prices at the time of delivery. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through revenue each period prior to settlement.  Changes in the prices of metals between the delivery and final settlement date will result in adjustments to revenues related to the sales of concentrate previously recorded upon delivery. Please see Note 14 to the Condensed Consolidated Financial Statements for additional information. 

Interest Rate Risk

Our outstanding debt, at fixed rates, consisted of an equipment loan and leased equipment classified as capital leases. As the debt is at fixed rates, we consider our interest rate risk exposure to be insignificant at this time.

Equity Price Risk

We have in the past sought and may in the future seek to acquire additional funding by sale of common stock and other equity. The price of our common stock has been volatile in the past and may also be volatile in the future. As a result, there is a risk that we may not be able to sell our common stock at an acceptable price should the need for new equity funding arise.

ITEM 4: Controls and Procedures

During the fiscal period covered by this report, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act are recorded, processed, summarized and reported within the required time periods and are designed to ensure that information required to be disclosed in our reports is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

There were no changes that occurred during the three months ended March 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The interim Condensed Consolidated Financial Statements (“interim statements”) of Gold Resource Corporation and its subsidiaries (collectively, the “Company”) are unaudited and have been prepared in accordance with the rules of the Securities and Exchange Commission for interim statements. Certain information and footnote disclosures required by United States Generally Accepted Accounting Principles (“U.S. GAAP”) have been condensed or omitted although the Company believes that the disclosures included are adequate to make the information presented not misleading. In the opinion of management, all adjustments (including normal recurring adjustments) and disclosures necessary for a fair presentation of these interim statements have been included. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. These interim statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2017 included in the Company’s annual report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements.  Unless otherwise noted, there have been no material changes to the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s annual report on Form 10-K.

Recently Adopted Accounting Pronouncements

Accounting Standards Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued guidance that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU was further amended in August 2015, March 2016, April 2016, May 2016 and December 2016 by ASU No. 2015-14, No. 2016-08, No. 2016-10, No. 2016-12 and No. 2016-20, respectively.  The guidance provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  On January 1, 2018, the Company adopted the new accounting guidance to all contracts using the retrospective approach.    The adoption of this new guidance did not result in any changes to previously reported revenue amounts.  Please see Note 3 for more information.

Recently Issued Accounting Pronouncements

Accounting Standards Update No. 2016-02 Leases (Topic 842). In February 2016, the FASB issued a new standard regarding leases. Lessees will be required to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and a lease liability. Public business entities are required to adopt the new leasing standard for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For calendar year-end public companies, this means an adoption date of January 1, 2019. Early adoption is permitted. The Company anticipates adopting the new guidance effective January 1, 2019.

The Company has begun its assessment of the new guidance and the impact it will have on the Consolidated Financial Statements and disclosures, and expects to complete its analysis in 2018. Management is still completing its assessment of the impacts; however, based on preliminary findings, the Company expects that the majority of its identified leases will be required to be reported on the Consolidated Balance Sheets.  Based on the preliminary assessment, the Company expects there will be minimal impacts to the Consolidated Statements of Operations. The Company expects to have an update to the impacts of the standard in the third quarter of 2018.

Total sales, net	$	32,151	$	24,336

Doré Revenue

Doré sales are recognized upon the satisfaction of performance obligations, which occurs when control of the doré transfers to the customer.  Transfer of control occurs once the customer takes possession of the doré.  Doré sales are recorded using quoted metal prices, net of treatment and refining charges.

Concentrates Revenue

Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of treatment and refining charges, at the time of delivery to the customer as that is when performance obligations are satisfied and control of the product is transferred to the customer.   Until final settlement occurs, adjustments to the provisional sales prices are made to take into account the mark-to-market changes based on the forward prices of metals for the estimated month of settlement.  The changes in price between the provisional sales price and final sales price are considered an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the quoted metal prices at the time of delivery. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through revenue each period prior to final settlement. Changes in the prices of metals that the Company sells, as quoted on the London Bullion Market, between the delivery and final settlement dates will result in adjustments to revenues related to sales of concentrate previously recorded upon delivery. Sales are recorded net of charges for treatment, refining, smelting losses and other charges negotiated with the buyer. These charges are estimated upon delivery of concentrates based on contractual terms and adjusted to reflect actual charges at final settlement. Historically, actual charges have not varied materially from the Company’s initial estimates.

6. Income Taxes

The Company recorded income tax expense of $3.6 million and $2.9 million for the three months ended March 31, 2018 and 2017, respectively.  The Company’s annualized effective rate differs from the U.S. corporate rate of 21% primarily due to differences in statutory rates for income and mining taxes in Mexico.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which significantly revised the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system, imposing a one-time tax on foreign unremitted earnings and setting limitations on deductibility of certain costs, among other things.  The Company has not revised any of the 2017 provisional estimates under SAB No. 118 and ASU No 2018-05.  The Company continues to gather information and is awaiting further guidance from the IRS, SEC and FASB on the Tax Act.

Mexico requires a 10% withholding tax on dividends to both residents and non-resident shareholders on all post-2013 earnings.  Dividends from earnings generated prior to 2014 were exempted from the new dividend withholding tax.  The Company plans to distribute post-2013 earnings from Mexico beginning in 2018.  According to the existing US – Mexico tax treaty, the dividend withholding tax between these countries is limited to 5% if certain requirements are met.  Based on the Company’s review of these requirements, it estimates it will pay a 5% withholding tax on dividends received from Mexico in 2018.  The impact of the planned annual dividends for 2018 is reflected in the estimated annual effective tax rate.

In 2015, the Mexican government approved a 2016 Federal Revenue Act that provides tax incentives, including tax credits on Mexican Excise Duty (a.k.a., IEPS), for the acquisition of combustible fossil fuels to be used in productive processes. The Company’s Mexican operations utilize a significant amount of diesel fuel for power generation that qualifies for such tax credits. These tax credits can be applied against income taxes payable, as well as other income tax withholdings during the year. In the three months ended March 31, 2018 and 2017, the Company recorded $1.1 million and $0.7 million, respectively, of fuel tax credits to offset production costs and such credits were applied against the income tax payable. 

As of March 31, 2018, the Company believes that it has no liability for uncertain tax positions.

Net Income per Common Share

17. Net Income per Common Share

Basic earnings per common share is calculated based on the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated based on the assumption that stock options outstanding, which have an exercise price less than the average market price of the Company’s common shares during the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds obtained from the exercise were used to purchase common shares at the average market price during the period. All the Company’s restricted stock units are considered to be dilutive.

The effect of the Company’s dilutive securities is calculated using the treasury stock method and only those instruments that result in a reduction in net income per common share are included in the calculation. Options to purchase 3.1 million and 2.8 million shares of common stock at weighted average exercise prices of $11.41 and $9.77 were outstanding at March 31, 2018 and 2017, respectively, but were not included in the computation of diluted weighted average common shares outstanding, as the exercise price of the options exceeded the average price of the Company’s common stock during those periods, and therefore are anti-dilutive.

Basic and diluted net income per common share is calculated as follows:

Fair Value Measurement

Fair Value Measurement

18. Fair Value Measurement

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth certain of the Company’s assets measured at fair value by level within the fair value hierarchy as of March 31, 2018 and December 31, 2017:  

	2018		2017		Input Hierarchy Level
	(in thousands)
Cash and cash equivalents:
Bank deposits	$	28,617	$	22,390	Level 1
Gold and silver rounds/bullion		3,826		3,812	Level 1
Accounts receivable:
Receivables from provisional concentrate sales		1,642		2,884	Level 2
	$	34,085	$	29,086

Cash and cash equivalents consist primarily of cash deposits and are valued at cost, which approximates fair value. Gold and silver rounds/bullion consist of precious metals used for investment purposes and in the dividend program which are valued using quoted market prices. Please see Note 4 for additional information. The Company determined that it was not practicable to estimate the fair value of its non-current investment in equity securities of $0.2 million and as such, it is reported at cost. There have been no events or changes in circumstances that may have a significant adverse effect on the investment.

Trade accounts receivable include amounts due to the Company for deliveries of concentrates and doré sold to customers. Concentrate sales contracts provide for provisional pricing as specified in such contracts. These sales contain an embedded derivative related to the provisional pricing mechanism which is bifurcated and accounted for as a derivative. At the end of each reporting period, the Company records an adjustment to sales to reflect the mark-to-market of outstanding provisional invoices based on the forward price curve. Because these provisionally priced sales have not yet settled as of the reporting date, the mark-to-market adjustment related to these invoices is included in accounts receivable as of each reporting date.  At March 31, 2018 and December 31, 2017, the Company had an unrealized loss of $0.03 million and an unrealized gain of $0.4 million, respectively, included in its accounts receivable on the accompanying Condensed Consolidated Balance Sheets.  Please see Note 14 for additional information.

Gains and losses related to changes in the fair value of these financial instruments were included in the Company’s consolidated statements of operations as shown in the following table:

The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. These interim statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2017 included in the Company’s annual report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements.  Unless otherwise noted, there have been no material changes to the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s annual report on Form 10-K.

Recently Adopted Accounting Pronouncements

Accounting Standards Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued guidance that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU was further amended in August 2015, March 2016, April 2016, May 2016 and December 2016 by ASU No. 2015-14, No. 2016-08, No. 2016-10, No. 2016-12 and No. 2016-20, respectively.  The guidance provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  On January 1, 2018, the Company adopted the new accounting guidance to all contracts using the retrospective approach.    The adoption of this new guidance did not result in any changes to previously reported revenue amounts.  Please see Note 3 for more information.

Recently Issued Accounting Pronouncements

Accounting Standards Update No. 2016-02 Leases (Topic 842). In February 2016, the FASB issued a new standard regarding leases. Lessees will be required to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and a lease liability. Public business entities are required to adopt the new leasing standard for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For calendar year-end public companies, this means an adoption date of January 1, 2019. Early adoption is permitted. The Company anticipates adopting the new guidance effective January 1, 2019.

The Company has begun its assessment of the new guidance and the impact it will have on the Consolidated Financial Statements and disclosures, and expects to complete its analysis in 2018. Management is still completing its assessment of the impacts; however, based on preliminary findings, the Company expects that the majority of its identified leases will be required to be reported on the Consolidated Balance Sheets.  Based on the preliminary assessment, the Company expects there will be minimal impacts to the Consolidated Statements of Operations. The Company expects to have an update to the impacts of the standard in the third quarter of 2018.

Revenue (Policy)

Revenue

Dore and Concentrate Revenue

Doré Revenue

Doré sales are recognized upon the satisfaction of performance obligations, which occurs when control of the doré transfers to the customer.  Transfer of control occurs once the customer takes possession of the doré.  Doré sales are recorded using quoted metal prices, net of treatment and refining charges.

Concentrates Revenue

Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of treatment and refining charges, at the time of delivery to the customer as that is when performance obligations are satisfied and control of the product is transferred to the customer.   Until final settlement occurs, adjustments to the provisional sales prices are made to take into account the mark-to-market changes based on the forward prices of metals for the estimated month of settlement.  The changes in price between the provisional sales price and final sales price are considered an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the quoted metal prices at the time of delivery. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through revenue each period prior to final settlement. Changes in the prices of metals that the Company sells, as quoted on the London Bullion Market, between the delivery and final settlement dates will result in adjustments to revenues related to sales of concentrate previously recorded upon delivery. Sales are recorded net of charges for treatment, refining, smelting losses and other charges negotiated with the buyer. These charges are estimated upon delivery of concentrates based on contractual terms and adjusted to reflect actual charges at final settlement. Historically, actual charges have not varied materially from the Company’s initial estimates.
