GOLDEN, Colo., April 16, 2012 /CNW/ - Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN/OTCBB:ATNAF) is pleased to report on the development progress of its 100 percent owned Pinson Mine development project near Winnemucca, Nevada. Atna is targeting the commencement of sustained gold production by year end 2012. Atna has focused on the following tasks in the first quarter:
- Senior management for the project has been retained and are now on-site.
- Mr. Rod Berkshire has joined Atna as General Manager for the Pinson Mine. Mr. Berkshire is a mining engineer by training with over 35 years of underground and surface mining operations experience.

- The mine design and reserve estimate for the Pinson underground is targeted for release by the end of April.
- The mining contractor, DMC Mining Services, is mobilized and three mining crews are working on site.
- Development of the secondary access is now 26 percent complete. Rehabilitation of the lower ramp in the mine is underway which will enable development of the secondary access from both ends.
- A total of approximately 1,500 tons of ore has been mined with an estimated gold grade of 0.36 oz/ton (1,360 tonnes at 10.l1 g/t Au). This material was mined to validate the mineral reserve model, assess ground conditions and to provide a bulk sample for metallurgical process tests. No significant issues were encountered in mining this material.
- The assay lab has been designed and construction quotes are pending.
- Negotiations are ongoing concerning third party processing of oxide ores.
- Metallurgical sample drilling in the Mag open pit has commenced. The 1,500 to 2,000-foot (460 to 610 meter) PQ core program will acquire 6 to 8 samples for column leach testing of the potential open-pit, heap leach, gold resources in the Mag pit. Column leach testing will be the focus of the metallurgical work with attention to crush size optimization, gold recovery optimization, evaluation of reagent costs, and the evaluation of any recovery issues associated with carbon or gold encapsulation.
"Work at Pinson is proceeding as planned and we are on target to begin sustained production by the end of 2012," states James Hesketh, President & CEO.
