Principal Minerals Uranium ore in the form of uraninite, with some autunite.

Number of Men Employed 4

Production Rate About 22 tons of Uranium ore has been stockpiled since work started • No shipments have been made to date.

Geology A vein about 40 inches wide, 24 inches of same containing Uranium Values, has been found ·between a hanging wall of shale and. a footwall ·of granite. . This vein dips about 80 degrees to the southwest and has been traced to date for a length of about 60 ft. The vein material is highly c.ompleJ[, containing chiefly magnetite, hematite, limonite, calcite, pyrite, chalcopyrite, and copper oxides and appears to 'be highly siliceous. The Atomic Energy Co~ission has repQrted that the Uranium contained in this vein is chiefly Uraninite, together with a small amount of autunite. Other ore pockets are also reported.

Ore Values Mr. Brooks estimates that a 15 ton stockpile near the workings will average about 1.5 % Uranium, and that a small' ore pile of about 7 tons will average about 0.9 % Uranium. He expects the ore mined will average close to 1.5 %. ~ estimates, judging from the geiger counter readings on same is somewhat less, but may approximate 1.0 %.

Ore in Sight and Probable Not enough informat~on to base any estimates of "probable orena. No ore blocked out to date.

Present Mine ~orkings (1) 1 shaft (vertical)----18 ft. deep,. now being driven. It is planned to sink this shaft to a depth of 120 ft. This shaft i .s a 4 t X 6', 1 1/2 compt. shaft

(2) 3 open cuts, exposing the vei~.
