| Abstract: | The Garm-Lamoreaux property, Lemhi County, Idaho is known to have uranite and zippsite on two of its dumps. The property has been explored by five adits, two of which are now caved, and one of which is partly caved. The country rock is schistose micaceous quartzite and argillaceous quartzite of Belt age. An east-west fault cuts the quartzite, and the Lamoreaux vein, a gold-sulfide-quartz vein, occurs in the fault. The uramium minerals are believed to have come from the vein, on the now inaccessible No. 3 level.
An alidade and plane-table map was made to tie in the positions of the five underground workings. The lowest adit, the first 200 feet of Tunnel 2 and the Eardrock tunnel were mapped. Maps of the other workings made by Gilbert in 1933 were combined with the writers maps.
Samples were collected from the radioactive parts of the number two and number three dumps. Chemical analyses of the samples showed a range from 0.001 to 0.54 percent uranium. It appears probably that at least some uranium could have been leached by sulfate-bearing waters in the dump material. The presence of as much as 0.54 uranium in one sample from the Tunnel 3 dump suggests that exploration program would be advisable. |
