| Deposit | SEVERAL MINERAL DEPOSITS OCCUR NEAR THE CONTACT OF A CRETACEOUS QUARTZ MONZONITE PLUTON BORDERED BY CRETACEOUS MARBLE METAMORPHOSED FROM SILURIAN HECETA LIMESTONE (BREW, AND OTHERS, 1984); ALL THE DEPOSITS ARE PROBABLY RELATED TO THIS CONTACT ZONE. AT THE LILLIE PROSPECT (DENNY, 1961; HERREID AND KAUFMAN, 1964) A BAND OF TACTITE ABOUT 100 FEET WIDE IN DIORITE CONTAINS JOINT COATINGS AND DISSEMINATED IRREGULAR MASSES, LESS THAN A HALF-INCH IN DIAMETER, OF MOLYBDENITE AND SUBORDINATE POWELLITE, CHALCOPYRITE, PYRITE, AND MAGNETITE. AT ANOTHER UNNAMED OCCURRENCE, A BAND OF MAGNETITE ABOUT 3 FEET WIDE FOLLOWS THE CONTACT BETWEEN A DIORITE DIKE AND MARBLE. AT ANOTHER, SAMPLES OF HORNFELS, MARBLE, AND DIORITE COLLECTED FROM A DUMP OUTSIDE A SHORT CAVED ADIT CONTAIN VARIABLE AMOUNTS OF MAGNETITE, MOLYBDENITE, CHALCOPYRITE, PYRRHOTITE, PYRITE, AND GALENA. QUARTZ VEINS NEAR THE ADIT CONTAIN SCHEELITE AND A 5-FOOT CHIP SAMPLE OF THE VEIN CONTAINED 1.4% WO3. QUARTZ-RICH ROCK NEAR A |
| Deposit | MARBLE-DIORITE CONTACT ALSO CARRY DISSEMINATED SCHEELITE. THESE AND ADDITIONAL SHOWINGS OF MOLYBDENITE, PYRITE, AND CHALCOPYRITE IN THE CONTACT ZONE OF THE PLUTON SUGGEST THE POSSIBILITY OF A PORPHYRY COPPER OR MOLYBDENUM DEPOSIT AS WELL AS MORE CONTACT METAMORPHIC DEPOSITS IN THE VICINITY. ALSO SEE 'WORKINGS/EXPLORATION'. |
