Comments

Comment (Workings): PROSPECT PITS, 50-FT ADIT, 20-FT SHAFT WITH SMALL STOPES.

Comment (Deposit): SCHEELITE OCCURS IN TACTITE ALONG A CONTACT BETWEEN CALCAREOUS HORNFELS AND GRANODIORITE, AND IN A TACTITE BED ABO-UT ONE FOOT WIDE INTERSTRATIFIED IN METASEDIMENTS. THE CONTACT- STRIKES NW AND DIPS STEEPLY. IT IS INTERSECTED AT RIGHT ANGLE-S BY THE HORNFELS WHICH STRIKES NE AND DIPS 45 SE.
