Deposit VEINS ARE FOUND IN A SHEAR ZONE THAT IS BETWEEN 60 AND 120 FT THICK
Deposit PLACER COVERS 5.3 HECTARES AND TRACE GOLD VALUES IN A PROSPECT PIT THAT ASSAYED 91.5 % FLUORITE. THE VEIN IS FOR ONLY 8 METERS. A VEIN 0.3 M THICK EXPOSED FOR 27 M IN A ASSAYED A TR AU, NO AG & NO FLUORITE. SOME AG-AU VALUES WERE OBTAINED FROM SAMPLES IN NEARBY TRENCHES & CUTS. THE PROPER NOT HAVE SIGNIFICANT FLUORITE RESOURCES, BUT MAY HAVE MINOR POSSIBILITIES AS A GOLD-SILVER PROPERTY. 12-76 THE PROPERTY WAS RESTAKED AS THE BRINDLE PUP GROUP BY CHAMBERS IN 1975, MAINLY AS A POTENTIAL AG-AU PROPERTY.
