VANCOUVER, British Columbia, Nov. 22, 2004 (PRIMEZONE) -- Atna Resources Ltd. (TSX Venture Exchange:ATN) is pleased to report that initial results from its drilling program at the Pinson Gold Project in Nevada confirm the continuity of high-grade gold mineralization between previous drill intercepts in the mineralized envelope around both the CX and Range Front zones. Gold mineralization was encountered in every drill hole submitted for assay with high-grade gold values in nearly all holes. Significant drill intercepts from completed holes in the current program include the following:

Atna has completed approximately half of the 29 drill holes/30,000 feet of drilling planned in the current program. Drilling consists of Reverse Circulation pre-collars followed by core tails through the mineralized interval. It is anticipated that a resource calculation consistent with NI43-101 standards will be carried out at the end of the drill program and will be ready early in the first quarter of 2005.
Drill samples are prepared and assayed by BSI Inspectorate Laboratories, an ISO certified laboratory, in Reno, Nevada. All gold analyses were done by standard fire assay with appropriate replicate and analytical standards to ensure high quality assurance and control.
