A former small underground Cu-Ag mine located in the SE ¼ sec. 36, T.17S., R.12E., ¼ mile west of the town of Twin Buttes, on private land. Produced 1918-1935. Owned/operated at times, or in part, by Twin Buttes Mining & Smelting Co.; Bush & Baxter; Lee S. Wood; Jesus Oritz; and, Foy.

Mineralization is a small zone of chalcopyrite in fractured, garnetized, Paleozoic limestone near, or at, a fault contact with Precambrian granite at the border of the Minnie claim. Other slightly mineralized, garnetiferous zones occur eastward along the limestone-granite fault contact.

Local structures include a NW-trending fault just to the north of the mine.

Workings include shaft operations from the Minnie Mine and Butte shaft. Possibly some 200 tons of ore, averaging about 3% Cu were produced in 1929.
