Subject category Comment text
Deposit AN 1,100 FT LONG AIRSTRIP HAS BEEN BUILT NEAR THE CLAIM. ADDITIONAL WORKINGS INCLUDE SEVERAL TRENCHES ON PB-AG MINERALIZATION APPROX. 1 MILE SW OF COSNA DOME. LACK OF SURFACE EXPOSURE PROHIBITS EVALUATION OF THE EXTENT OF MINERALIZATION. HOWEVER, THE ABUNDANCE OF VEIN-TYPE OCCURRENCES IN THE LIMITED EXPOSURES POINTS TO POSSIBLE SIGNIFICANT MINERALIZATION AT DEPTH.
