Pinson Open Pit Project Drilling Returns 0.098 oz/ton Au over 162 feet
by PR Newswire
GOLDEN, Colo., Nov. 15, 2012 /PRNewswire/ -- Atna Resources Ltd. ("Atna" or the "Company") (TSX:ATN/OTCQB:ATNAF) is pleased to provide head grade assay results from the Mag Pit metallurgical drilling program at its Pinson Mine near Winnemucca, Nevada. In May and June of this year, Atna completed four large diameter core holes to confirm continuity of mineralization and to acquire metallurgical sample materials from the potential open pit resource in the Mag Pit area of the property. The Mag Pit zone is separated from the underground mine and may be developed independently after permitting is completed. Head assay results confirm the grade and continuity of the modeled resource and will provide sample material for the metallurgical work which is underway, as part of a prefeasibility study.
Highlights from the drill results include:
- 154.5 feet (47.1 m) grading 0.057 oz/ton gold (1.97 g/t gold) in hole Magmet-001
- 238 feet (72.5 m) grading 0.041 oz/ton gold (1.40 g/t gold) in hole Magmet-001
- 162 feet (49.4 m) grading 0.098 oz/ton gold (3.36 g/t gold) in hole Magmet-002
- 41 feet (12.5 m) grading 0.059 oz/ton gold (2.03 g/t gold) in hole Magmet-003
"This drilling was successful in confirming strong continuity of the gold resource remaining in the Mag pit. Gold was previously produced from the Mag pit by conventional open pit, heap leach methods. Production ceased in 1999 due to low gold prices. Information from this metallurgical study program will be utilized to confirm past results and to provide additional data for process design. A reputable engineering firm has been retained to complete a pre-feasibility study to demonstrate the potential economic viability of developing an open-pit heap leach operation at Pinson. The study is targeted for completion in the first half of 2013," states Atna's President & CEO, James Hesketh.
