Deposit: Vein is 6 to 26 in wide at a depth of 160 ft.; Boston Sierra Mine Industry Co. reported a 1700 ft long pay streak with a 300 ft long by 6 to 18 in wide ore shoot. Cross-cut vein is 23 ft wide and mineralized throughout much of its width.

Deposit type: Low-sulfide Au-quartz vein

Geology: Granite and diorite dikes trend NW and dip NE, and are cut by N45W-trending qtz vein (North Fork vein). A N88E-trending crosscut vein cuts the N. Fork vein. NE trending fault crosses the properties
