Mt. Edna consits of 36 lode mining claims located over part of a possible early stage gold-copper porphyry prospect in southeastern Humboldt County, Nevada, about 10 miles southeast of the town of Golconda. The claims cover the southern part of the prospect and adjoin Newmont-owned private mineral rights that cover the northern portion of the target. As part of Atna's Asset Exchange Agreement, Atna was granted a right of first opportunity to acquire the Newmont owned mineral rights should they decide to transfer all or part of their interest in this property.
The prospect is centered on a small granodiorite porphyry intrusive body of Cretaceous Age cutting limestone and quartzite of the Paleozoic Havallah and Pumpernickel Formations. The sedimentary rocks have been recrystalized and display widespread patchy, weak skarn development. Traces of copper oxide minerals coating fractures are widely distributed over and around the prospect. The intrusive is moderately to intensely quartz-sericite altered and contains from one to plus ten percent disseminated pyrite and pyrrhotite and trace to one percent disseminated chalcopyrite. Abundant copper oxide was reported in the upper two hundred feet of six reverse circulation holes originally drilled in the 1980's to test a gold-bearing quartz vein on the edge of the Newmont controlled ground.
We plan to map the property during the 2007 field season.
