Comments
Comment (Geology): LITTLE INFORMATION AVAILABLE. GEOLOGY PRESUMED SIMILAR TO THAT AT OTHER PROPERTIES IN DISTRICT. THIS DEPOSIT IS FAR ENOUGH OUT FROM THE CENTER OF MINERALIZATION THAT THERE IS A POSSIBILITY FOR THE PRESENCE OF STIBNITE. DIORITIC DIKES AND PLUGS PRESENT IN DISTRICT

Comment (Commodity): COMMODITIES AND ORE MINERALS PRESUMED SIMILAR TO THOSE AT OTHER PROPERTIES IN DISTRICT
Comment (Workings): SEVERAL LARGE OPEN CUTS, 400 FT OF WORKINGS
