CUSIP No. 827692104

Item 1. Security and Issuer

This Schedule 13D relates to shares of Common Stock, $0.0001 par value (the “Common Stock”) of Silver Dragon Resources Inc., a Delaware corporation (the “Issuer”). The principal executive office and mailing address of the Issuer is 200 Davenport Road, Toronto, Ontario Canada, M2R 1J2.

Item 2. Identity and Background

This Schedule 13D is jointly filed by:

These individuals are collectively referred to herein as the “Reporting Persons” and each separately a “Reporting Person.” The Reporting Persons are making this single joint filing, because they may be deemed to constitute a “group” within the meaning of Rule 13d-5 and/or Section 13(d)(3) of the Act as of April 12, 2013, the date of the Voting Agreement by and among the Reporting Persons described in Item 6 below, although neither the fact of this filing nor anything contained herein shall be deemed to be an admission by the entities or person that such a group exists. Each Reporting Person (with the exception of the Ms. Chan King Yuet) have appointed Ms. Chan King Yuet as the stockholder representative (the “Representative”) of the group that may be deemed to have been formed, as set forth in the Voting Agreement.

The address for each of the Reporting Persons is as follows:

The present principal occupation or employment of the Reporting Persons is as follows:

The citizenship of the Reporting Persons is as follows:

None of the Reporting Persons identified in this Item 2 has, during the past five years, been convicted of any criminal proceeding (excluding traffic violations or similar misdemeanors), nor been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

The source of the funds for each of the above were the personal funds of each individual Reporting Person.

Item 4. Purpose of Transaction

The Reporting Persons purchased the Common Stock based on the belief that such securities, when purchased, were undervalued and represented an attractive investment opportunity. The purpose of the acquisitions of the Common Stock was for investment, and the acquisitions of the Common Stock were made in the ordinary course of business and were not made for the purpose of acquiring control of the Issuer.

On September 17, 2012, trading in shares of the Issuer’s Common Stock were suspended by the United States Securities & Exchange Commission. Subsequent to this date, Ms. Chan King Yuet and Marc Hazout, the president and chief executive officer of the Issuer, engaged in ongoing discussions regarding Ms. Chan and other prospective investors known to Ms. Chan providing working capital required by the Issuer. On November 1, 2012, Ms. Chan made a specific proposal to fund the working capital needs of the Issuer until such time as the Issuer became cash flow positive. The offer was conditioned, among other matters, upon members of the investor group being appointed to a majority of the Issuer’s Board of Directors. On November 3, 2012, Mr. Hazout formally rejected Ms. Chan’s proposal and advised Ms. Chan that the Board of Directors of the Issuer had determined to pursue alternative financing. In a report on Form 8-K filed by the Issuer on November 19, 2012, the Issuer announced that it had entered into a loan arrangement with a company controlled by Mr. Hazout. The 8-K filing provided no details about whether the loan arrangement was sufficient to meet the Issuer’s future working capital needs or to repay the so-called “toxic” loans made to the Issuer.

On November 20, 2012, in a report on Form 8-K, the Issuer disclosed that its auditors had filed a notice of non-compliance advising that the Issuer’s financial statements could no longer be relied upon. The Issuer has also not filed its required Form 10-Q for the quarter ended September 30, 2012. Finally, the Issuer has reported on Form 8-K that it has entered into forbearance agreements with holders of its toxic loans but the Issuer has not disclosed how it intended to finance the repayment of these loans.

Although no Reporting Person has any specific plan or proposal to acquire or dispose of the Common Stock owned by any of them, consistent with its investment purpose and in light of the circumstances described above, each Reporting Person at any time and from time to time may acquire additional Common Stock or dispose of any or all of its Common Stock depending upon an ongoing evaluation of the investment in the Common Stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Persons, and/or other investment considerations.

Consistent with their investment purpose and in light of the developments described above, the Reporting Persons may engage in communications with one or more stockholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to its operations, and plans of the Reporting Persons. The Reporting Persons may discuss ideas that, if effected may result in a change in any of the following: the acquisition by persons of additional Common Stock of the Issuer, an extraordinary corporate transaction involving the Issuer, and/or other changes in the board of directors or management of the Issuer.

Except as disclosed above, none of the Reporting Persons has any other plans or proposals which relate to, or would result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

Item 5. Interest in Securities of the Issuer

(a) and (b) According to the Issuer’s most recent Quarterly Report on Form 10-Q filed August 14, 2012, there were 246,017,263 shares of Common Stock issued and outstanding as of August 2, 2012. The group that may have been deemed to be formed by the Reporting Persons may be deemed to beneficially own 23,631,584 shares of Common Stock of the Issuer held by all of the Reporting Persons combined (9.6% of the Common Stock of the Issuer based upon the information contained in the above-referenced Form 10-Q), and each of the Reporting Persons may be deemed to beneficially own the shares of each other Reporting Person.

Each Reporting Person disclaims beneficial ownership of any shares of Common Stock beneficially owned by any other Reporting Person.

As of the date hereof, no Reporting Person owns any shares of Common Stock other than those set forth in this Item 5.

(c) During the last 60 days no Reporting Person had any transactions in the shares of Common Stock of the Issuer.

(d) Not applicable

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

On April 12, 2013 the Reporting Persons entered into a Voting Agreement (the “Voting Agreement”), pursuant to which, among other things, such Reporting Persons agreed to form a group for the purposes of engaging in communications with stockholders, officers, members of the board of directors and/or representatives of the Issuer regarding the Issuer, the Issuer’s operations, the acquisition by persons of additional common shares of the Issuer, an extraordinary corporate transaction involving the Issuer, possible changes in the board of directors or management of the Issuer, and plans of the group and for the purpose of taking all other actions necessary to achieve the foregoing (collectively, the “Purposes”).

WHEREAS, each of the Stockholders owns or controls voting securities of Silver Dragon Resources Inc., a Delaware corporation (the “Issuer”);

WHEREAS, the Stockholders desire to form a group (the “Group”) for the purposes of engaging in communications with stockholders, officers, members of the board of directors and/or representatives of the Issuer regarding the Issuer, the Issuer’s operations, the acquisition by persons of additional common shares of the Issuer, the Issuer’s operations, an extraordinary corporate transaction involving the Issuer, possible changes in the board of directors or management of the Issuer, and plans of the Group and for the purpose of taking all other actions necessary to achieve the foregoing (collectively, the “Purposes”).

NOW THEREFORE, in consideration of these premises and the mutual covenants and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by each party, the parties hereto agree as follows:

1. Each of the Stockholders (with the exception of Chan King Yuet) hereby (i) appoints Chan King Yuet as the stockholder representative (the “Representative”) of the Group, to communicate with the Issuer on behalf of the Group with respect to the Purposes, (ii) grants the Representative shared voting power over the common shares of the Issuer (the “Shares”) held by each respective Stockholder in the Group, and (iii) authorizes the Representative to execute and file with the Securities and Exchange Commission a Schedule 13D and any amendments thereto on their behalf relating to the Purposes and/or their holdings of the Shares held by each of the respective Stockholders. For the avoidance of doubt, the Stockholders do not grant the Representative dispositive power (i.e., the ability to directly or indirectly to purchase, sell or otherwise transfer) over the Shares, and Representative shall not exercise dispositive power with respect to any Shares held by any Stockholder other than herself.

2. Each of the Stockholders hereby covenants and agrees that, during the term of this Agreement, in any circumstances upon which a vote, consent (including unanimous written consents), agreement or other approval of the common shares of the Issuer is sought, such Stockholder shall vote (or cause to be voted) all of the voting securities of the Issuer owned or controlled by him/her (whether now owned or hereafter acquired) and shall otherwise consent or agree in such manner as may be directed by the Representative in her sole and absolute discretion, in pursuit of the Purposes. Each of the Stockholders, as a holder of voting securities of the Issuer, shall be present in person or by proxy at all meetings of stockholders of the Issuer, including, without limitation, any Special Meetings, so that all voting securities held by such Stockholder are counted for purposes of determining the presence of a quorum at such meeting.

3. Each of the Stockholders hereto represents that he/she has full power to enter into this Agreement and has not, prior to the date of this Agreement, executed or delivered any proxy or entered into any other voting agreement or similar arrangement with respect to the securities of the Issuer, other than one that has expired or terminated prior to the date hereof.

4. So long as this Agreement is in effect, each of the Stockholders shall provide written notice to Representative and her counsel, Crowell & Moring LLP (“Crowell & Moring”), of (i) any of their purchases or sales of securities of the Issuer, or (ii) any securities of the Issuer over which they acquire or dispose of beneficial ownership. Notice shall be given no later than 24 hours after each such transaction.

5. The relationship of the parties hereto shall be limited to carrying on the business of the Group in accordance with the terms of this Agreement in pursuit of the Purposes.

Nothing herein shall be construed to authorize any party to act as an agent for any other party, with the exception of the Representative as set forth above, or to create a joint venture or partnership, or to constitute an indemnification. Nothing herein shall restrict any Stockholder’s right to purchase or sell securities of the Issuer, as he/she deems appropriate, in his/her sole discretion, provided that all such purchases and sales are made in compliance with all applicable securities laws.

6. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which, taken together, shall constitute but one and the same instrument, which may be sufficiently evidenced by one counterpart.

7. In the event of any dispute arising out of the provisions of this Agreement or their investment in the Issuer, the parties hereto consent and submit to the exclusive jurisdiction of the Federal and State Courts in the State of New York.

8. This Agreement shall not be terminable for a period of 90 days from the date hereof, except in a writing signed by all parties hereto.
