Net income for the year ended December 31, 2016 was $17.9 million ($0.13 basic earnings per share) compared to a $10.6 million net loss ($0.08 loss per share) for the comparable year in 2015. Adjusted net income for 2016 was $18.2 million compared to $6.7 million in 2015. The higher net income was driven mostly by higher metal sales across all our products and higher realized metal prices. Silver and gold metal sales increased 11% and 17%, respectively, while realized metal prices increased 10% to $17.20 per ounce for silver and 8% to $1,253 per ounce for gold. This increase in net income was partially offset by higher selling, general, and administrative expenses of $13.4 million over 2015 due primarily to changes in the fair value of share-based compensation instruments based on the performance of our share price. The share-based compensation expense in 2016 was $14.1 million compared to $1.5 million in 2015.

Cash provided by operating activities was $52.7 million, slightly below the $54.8 million recorded in 2015. This reduction is explained by certain timing differences in the collection of accounts receivable from one year to the next offset by higher Adjusted EBITDA in 2016.

During the fourth quarter ended December 31, 2016, the Company revised its methodology to calculate Adjusted EBITDA to exclude share-based payments. Adjusted EBITDA in 2016 increased 67% to $83.0 million over 2015, driven by a 62% increased contribution from San Jose of $31.1 million and a 152% increase of $15.2 million at Caylloma.

Net income for the fourth quarter 2016 was $6.5 million ($0.04 earnings per share) compared to a $17.3 million loss ($0.13 loss per share) for the comparable period in 2015. Adjusted net income for fourth quarter 2016 was $8.8 million compared to $0.1 million loss for the comparable period in 2015. The higher net income was driven by higher silver and gold metal sold of 32% and 40% as well as higher realized prices for silver, gold, zinc, and lead. Net income for the fourth quarter was also positively impacted by a $2.5 million decrease in selling, general and administrative expenses over the comparable period in 2015 due to lower stock based compensation expenses.

Cash provided by operating activities during the fourth quarter 2016 was $25.8 million compared to $23.2 million for the comparable period in 2015.

Adjusted EBITDA for the fourth quarter 2016 increased 167% to $29.4 million over the comparable period in 2015. This was driven by a 76% increase of $9.7 million at San Jose and a 429% increase of $6.0 million at Caylloma. Adjusted EBITDA margin increased significantly from 30% to 51% as a result of higher margins at both Caylloma and San Jose.

At December 31, 2016, the Company had cash and short-term investments totaling $123.6 million (December 31, 2015 – $108.2 million).

Evaluation of internal control over financial reporting and disclosure controls and procedures

In its assessment of the effectiveness of the design and operation of internal control over financial reporting, management concluded that certain internal controls were not operating effectively, and as such material weaknesses were identified. We did not complete a documented fraud risk assessment, we did not identify all risks and we did not design relevant controls related to significant unusual transactions and complex accounting matters. We did not address all the risks and controls related to revenue recognition, our controls related to tax provisions were not sufficiently precise and we did not implement effective general information technology controls related to user access privileges, unauthorized access and segregation of duties.

Management has commenced remediation of these material weaknesses in 2017.

* Net of by-product credits from gold

Silver and gold annual production for 2016 increased 24% and 19% respectively to 6,124,235 and 46,018 ounces of silver and gold respectively above the prior year’s production. The increases were the result of higher throughput of 26% and higher recoveries of 1 percentage point for both silver and gold offset by lower head grades of 3% for gold and 6% for silver. Silver and gold annual production were 4% and 10% above 2016 guidance.

Cash cost per tonne of processed ore for 2016 was $56.90, or 3% below the cost in the prior year. Cash cost in the second half of 2016 was $55.0 compared to $59.8 in the first half of the year reflecting the positive impact on unit costs of the expanded plant capacity commissioned in July. Cash cost per tonne for 2016 of $56.90 was in line with guidance for the year as a result of an average exchange rate 19% above our assumption for cost guidance, offset by higher costs related to the filtration plant. Excluding this effect, the cash cost would have been 7% above guidance.

All-in sustaining cash cost per payable ounce of silver, net of by-product credits, was $7.58 for 2016, and below the annual guidance of $9.10 as a result of by-product credits and lower execution of sustaining capital expenditures.

Lead and zinc annual production for 2016 increased 37% and 21% to 32.7 million and 43.2 million lbs respectively, offset by silver and gold annual production which decreased 26% and 54% respectively to 1.3 million and 533 ounces of silver and gold respectively below the prior year’s production. The changes were the result of higher head grades of 24% for lead and 11% for zinc offset by lower head grades of 23% for gold and 34% for silver. Compared to 2016 guidance, silver was 5% above, while gold, lead, and zinc were 41%, 23%, and 1% below.

5

Cash cost per tonne of processed ore for 2016 was $71.89, a decrease of 16% from the same period in the prior year mainly related to lower mining costs as result of the cessation of mining in the narrow high grade silver veins, lower indirect costs related to headcount, and the plant optimization.
