This property consists of a claim adjoining the Eclipse on the east and is owned by the Ophir Mining and Milling Company. It is developed by a tunnel entering under the Midland [Terminal] trestle, 40 feet above the Eclipse and by a shaft 500 feet deep, 350 feet east-southeast of the Eclipse shaft, the elevation of the collar being 9,910 feet.
Drifts aggregate about 1,500 feet. No work was done in 1904. The workings connect in part with those on the Eclipse. The production is considerable, but the exact amount could not be ascertained.
The Carbonate Queen has the same flat, westward-dipping vein as the Eclipse, and some ore has been extracted from it. There is also a north-south vein and several others trending east and west. The country rock is breccia.
