VANCOUVER, B.C., Sept. 29, 2004 (PRIMEZONE) -- Atna Resources Ltd. (TSX:ATN) has received additional reassay results from its Pinson project, Nevada. Intercepts of gold mineralization from previous drilling below the open pits in the CX and Range Front zones are being reassayed to enable integrating the data into planned resource calculations. Reassay results reported in the table below confirm the high grade nature of the principal feeder structures to the CX open pit gold deposit, where production ceased in 2000. Data from the 11 holes in the table below and from 2 previously reported drill holes (September 8, 2004) suggest continuous gold mineralization in the CX zone from subsurface for over 1400 feet down dip. Multiple mineralized intercepts in some of the holes suggest the possibility that new zones of mineralization may remain to be discovered.

Assays were completed by standard fire assay methods at ALS Chemex laboratories in Reno, Nevada. The variability of the reassays versus the original assays is generally less than +/-5%. Atna's quality assurance and control program shows strong reproducibility of analytical standard samples and the variance is well within industry standards for assay reproducibility. All drill holes are inclined and intersect moderate to steeply dipping mineralized horizons at high angles. Three drills are presently engaged on the property. Atna plans to integrate reassay data with the results of its own drill program to calculate a resource estimate in January. Additional results from the reassay program and from new drill holes in the current drill program will be made available upon receipt of assays and completion of check analyzes of mineralized intercepts.
