Deposit QUARTZ LATITE DIKES RADIATE FROM POST-BLOCK FAULT ACIDIC PLUG THAT INTRUDES SATELLITE DIORITE STOCK OF TWIN LAKES BATHOLITH ON TRACE OF LINCOLN GULCH FAULT. SAWMILL PLUG IS ONE OF SEVERAL INTRUSIONS ON ARCUATE ZONE EXTENDING FROM PINE-BOWMAN CREEK DIVIDE TO WEST RED MTN. AND MAY POSSIBLY CONNECT WITH RING DIKE AT DEPTH. PLUG COMPOSED OF BANDED FELSITE PORPHYRY CENTER GRADING INTO PYROCLASTIC CORE CUT BY SEVERAL VUGGY RHYOLITE DIKES. CONTACTS OF PLUG AND DIORITE GENERALLY MARKED BY GLASSY PORPHYRY AND BY 50-FT-WIDE BRECCIA ON NE EDGE. ALTERATION CONSISTS OF QUARTZ-SERICITE-PYRITE CORE ENCLOSED IN QUARTZ-SERICITE ZONE ENCLOSED IN ARGILLIC ZONE. PLUG BELIEVED TO POSTDATE CAULDRON DEVELOPMENT AND WAS LOCALIZED ON NNW-TRENDING BLOCK FAULT BECAUSE 1) IT IS MORE ACIDIC THAN EARLIER MAFIC INTRUSIONS; AND 2) LACK OF OFFSET ON LINCOLN GULCH FAULT.
