| Deposit | THE COUNTRY ROCKS IN THE AREA OF THE ALASKA-PREMIER PROSPECT ARE PELITIC METASEDIMENTARY AND SUBORDINATE ANDESITIC (GREENSTONE) METAVOLCANIC STRATA OF THE JURASSIC OR OLDER MESOZOIC HAZELTON GROUP; THE TRIASSIC TEXAS CREEK GRANODIORITE, WHICH UNDERLIES AND LOCALLY INTRUDES THE HAZELTON; THE EOCENE BOUNDARY GRANODIORITE, WHICH INTRUDES THE HAZELTON AND TEXAS CREEK ROCKS; AND STILL-YOUNGER TERTIARY LAMPROPHYRE DIKES, WHICH CUT ALL THE OTHER ROCKS (SMITH, 1973, 1977, KOCH, 1996). THE DEPOSIT (BUDDINGTON, 1925, P. 74, 78-79; 1929, P. 85-86) IS IN GREENSTONE, SLATE, AND GRAYWACKE COUNTRY ROCKS. IT CONSISTS OF SULFIDE-BEARING QUARTZ VEINLETS IN SHATTERED ZONES IN THREE SHEETS OF ALTERED 'FELSITE,' WHICH MAY BE EITHER QUARTZ PORPHYRY SILLS OR A FACIES OF THE GREENSTONE. THE VEINS CONTAIN PYRITE, SPHALERITE, GALENA, PYRRHOTITE, AND CHALCOPYRITE; SELECTED SAMPLES REPORTEDLY ASSAYED AS HIGH AS 35 OZ AU PER TON. A 3-FOOT THICK MINERALIZED SHEAR ZONE IN A FELSITE SHEET CONTAINS |
| Deposit | DISSEMINATED(?) PYRITE, GALENA, SPHALERITE, CHALCOPYRITE, TETRAHEDRITE, PYRRHOTITE, AND ARSENOPYRITE. ASSAYS OF SOME OF THE MINERALIZED FELSITE SHOWED ABOUT 0.097-0.145 OZ AU AND ABOUT 1.0 OZ AG PER TON. LEAD-ISOTOPE STUDIES OF GALENA FROM THE ALASKA-PREMIER PROSPECT (MAAS AND OTHERS, 1995, P. 254) INDICATE THAT THE DEPOSIT IS JURASSIC IN AGE, CONTEMPORANEOUS, AT LEAST IN PART, WITH ISLAND-ARC VOLCANISM IN HAZELTON TIME (ALLDRICK, 1993). |
| Deposit | PROPERTY PROBABLY ORIGINALLY STAKED IN EARLY 1920'S. THE ALASKA-PREMIER SITE PROBABLY INCLUDES THE OLD READY MONEY AND ALASKA CLAIMS (COBB, 1978, P. 92-93). |
