Subject category Comment text
Deposit THIN LIMESTONE BEDS ARE CUT BY AN IRREGULAR GRANODIORITE CONTACT, AND THEY ARE ONLY PARTLY ALTERED TO TACTITE. ON THE MAMMOTH CLAIM, PARTLY ALTERED LIMESTONE CONTAINS SPARSE SCHEELITE, ALTHOUGH SOME OF THE CRYSTALS ARE NEARLY AN INCH IN DIAMETER. THE TACTITE CONTAINS ABUNDANT GARNET CRYSTALS IN QUARTZOSE LENTICULAR LAYERS. MOST OF THE ROCK IS CRYSTALLINE CALCITE WITH ONLY MINOR EPIDOTE. AT THE NORTHERNMOST PROSPECT ON THE MAMMOTH CLAIM A GARNETIZED LAYER, WITH GARNETS AS MUCH AS 2 INCHES IN DIAMETER IS EXPOSED BY AN OPEN CUT AND SHORT ADIT. THE LAYER IS 4 FT THICK, BUT CONTAINS NO VISIBLE SCHEELITE. ON THE SCHEELITE EXTENSION CLAIM, SOUTH OF THE MAMMOTH CLAIM, 2 ADITS EXPLORE LIMESTONE BEDS WITH MANY THIN LAYERS OF SILICATE ROCK BUT NO TACTITE. MATERIAL ON THE DUMPS CONTAINS SOME GARNET AND EPIDOTE WITH ABUNDANT QUARTZ AND CALCITE, BUT NO SCHEELITE. ON THE DON CLAIM, SOUTH OF THE SCHEELITE EXTENSION, 4 ADITS EXPLORE PARTIALLY ALTERED LIMESTONE BEDS. SOME CLUSTERS OF
Deposit COARSE-GRAINED EPIDOTE OCCUR LOCALLY WITH A FEW SPARSE CRYSTALS OF SCHEELITE, BUT NO MINEABLE ORE WAS FOUND.
