Vancouver Recent underground drilling by Atna Resources (ATN-T) has returned an impressive 147.5-ft. intersection grading 0.97 oz. gold per ton from the Ogee zone discovery at the past-producing Pinson mine project in northeastern Nevada.
The high-grade mineralization was intersected by the first underground hole drilled in the Ogee zone, a recently discovered target not included in a resource estimate released earlier this year. Existing measured and indicated resources in the parallel Range Front and CX zones total 1.75 million tons grading 0.3 oz. gold per ton, using a 0.15 oz. cutoff grade, while inferred resources add another 4.2 million tons of 0.32 oz. gold.
The high-grade intersection at the Ogee zone included a 54.6-ft. interval grading 1.29 oz. gold and a 37.3-ft. interval of 1.32 oz. The true width of the mineralized intersection is not yet known, however the company states that it is “significantly broader than expected.”
The mid-point of the 147.5-ft. intersection is located 145 ft. north and 175 ft. below adit-level channel samples that averaged 34 ft. grading 0.69 oz. gold. The true width is not known, though the company says it is “significantly broader than expected.”
Assays are pending from three additional holes completed in the Ogee zone. Drilling is continuing from an underground tunnel that will allow the zone to be drilled over 450 feet of strike and up and down dip.
The Pinson project lies within the Getchell gold belt and has produced almost 1 million oz. gold from shallow oxidized pits before mining ceased in 2000. The ‘Carlin-type’ gold system features micron-gold hosted in altered, fine-grained sedimentary rocks.
Atna holds rights to earn a 70% interest in the project from a subisidary of Barrick Gold (ABX-T, ABX-N).
