This constitutes Amendment No. 4 to the statement on Schedule 13D (the “Amendment No. 4”) filed on behalf of Lloyd I. Miller III (“Miller” or the “Reporting Person”), dated and filed January 7, 2011, as amended (the “Statement”), relating to the common stock, without par value per share, of Atna Resources Ltd. (the “Company” or “Atna”). The Company’s principal executive offices are located at 14142 Denver West Parkway, Suite 250, Golden, Colorado 80401. This Amendment No. 4 is being filed to report that since the filing of Amendment No. 3 to the Statement, dated May 12, 2011, a material change occurred in the percentage of the shares of Company common stock (the “Shares”) beneficially owned by Miller. Unless specifically amended or modified hereby, the disclosure set forth in the Statement shall remain unchanged.

Item 3.      Source and Amount of Funds or Other Consideration

Item 3		of the Statement is hereby amended and restated in its entirety as follows:

     Miller is the investment advisor to Trusts A-4 and Trust C (collectively, the “Trusts”). The Trusts were created pursuant to an Amended and Restated Trust Agreement, dated September 20, 1983 (the “Trust Agreement”). Pursuant to a Declaratory Judgment, signed by the Honorable Wayne F. Wilke for the Court of Common Pleas, Probate Division, Hamilton County, Ohio, on October 27, 1992, Trust A was split into four separate trusts, one of which was Trust A-4. The Trusts were further reformed by Order of the Delaware Chancery Court dated December 23, 2010, such Order naming Miller as investment adviser to the Trusts with enumerated powers. All of the Shares purchased by Trust A-4 were purchased with funds generated and held by Trust A-4. The aggregate purchase price for the Shares purchased by Trust A-4 was $1,151,411.68. All of the Shares purchased by Trust C were purchased with funds generated and held by Trust C. The aggregate purchase price for the Shares purchased by Trust C was $397,944.47.

     Miller is the manager of Milfam LLC, an Ohio limited liability company established pursuant to the Operating Agreement of Milfam LLC, dated as of December 10, 1996. Milfam LLC is the general partner of Milfam II L.P. (“Milfam II”), a Georgia limited partnership established pursuant to the Partnership Agreement for Milfam II L.P., dated December 11, 1996. All of the Shares Miller is deemed to beneficially own as the manager of the general partner of Milfam II were purchased with money contributed to Milfam II by its partners or money generated and held by Milfam II. The aggregate purchase price for the Shares purchased by Milfam II was $3,248,696.43.

     Miller is the settlor of an individual retirement trust account (the “IRA”). All of the Shares held by the IRA were purchased with personal funds generated and contributed to the IRA by Miller. The purchase price for the Shares held by the IRA was $6,177.29.

     Pursuant to an Irrevocable Trust Agreement MILGRAT I (V6) (“MILGRAT I (V6)”), dated as of November 20, 2009, Miller was named as the trustee to MILGRAT I (V6). All of the Shares Miller is deemed to beneficially own as trustee of MILGRAT I(V6) were contributed to MILGRAT I (V6) by its grantor, Catherine C. Miller.
