| Deposit | THE DEPOSITS WERE DEVELOPED FROM 1900 TO 1910 IN A SEARCH FOR GOLD ORE. ONLY A FEW TONS OF ORE WAS EVER SHIPPED TO THE SHELTER. THE ORE DEPOSITS ARE IN A PERIDOTITE DIKE OR INTRUSIVE THAT IS INTERSPERSED WITH SMALL BLEBS AND SEAMS OF SERPENTINE, ACTINOLITE AND TREMOLITE. AT SEVERAL PLACES IN THE MASS SMALL DEPOSITS OF NICKEL AND COPPER SULFIDES OCCUR. THE PERIDOTITE IN WHICH THE PRINCIPAL ORE DEPOSITS OCCUR IS A DENSE, DARK COLORED, FINE GRAINED ROCK THAT HAS BEEN PARTLY SERPENTINIZED. THE PRINCIPAL ORE DEPOSITS OCCUR ALONG A SHEAR ZONE THAT STRIKES N32 DEGREES W AND DIPS NEARLY VERTICAL. COBALT ASSAYS ABOUT 0.05 PERCENT |
