| Deposit | A RAISED TERRACE OF CLAY AND GLACIAL DEPOSITS EXTENDS UP METAL CREEK AND GLACIAL DEBRIS COVER MOST OF THE HIGH VALLEYS. PLACER GOLD IS LARGELY RESTRICTED TO LOWER HALF OF METAL CREEK AND IS PROBABLY DERIVED FROM SOURCE IN BASIN SUCH AS SMALL QUARTZ VEINS. THE GOLD APPARENTLY WAS DEPOSITED IN A GLACIAL LAKE AND IS CURRENTLY BEING REWORKED BY PRESENT STREAM ACTION. GENERALLY, GOLD IS WELL ROUNDED AND LESS THAN 1 MM IN DIAMETER. THE MAXIMUM GOLD CONTENT OCCURS BELOW 600 FT ELEVATION, THUS CORRESPONDING ROUGHLY TO THE HEIGHT OF THE OLD GLACIAL LAKE TERRACE SURROUNDING THE LOWER COURSE OF THE CREEK (RICHTER, 1967). PLATINUM, PYRITE, ZIRCON, COPPER, NATIVE SILVER, AND FAIRLY ABUNDANT SCHEELITE ARE PRESENT IN MANY CONCENTRATE SAMPLES. COUNTRY ROCK ALONG METAL CREEK IS VALDEZ GROUP INTERBEDDED SLATE, SILTSTONE, AND GRAYWACKE OF LATE CRETACEOUS AGE THAT HAVE BEEN METAMORPHOSED TO PHYLLITE AND QUARTZ MICA SCHIST. THESE ROCKS ARE TIGHTLY FOLDED, EXHIBIT STRONG FOLIATION, STRIKE N 10-30 |
| Deposit | E, AND DIP NEARLY VERTICAL. AT THE HEADWATERS OF METAL CREEK AND GLACIAL FORK, GREENSTONE CONTAINING DISCONTINOUS DIKES AND ONE STOCK OF QUARTZ DIORITE ARE PRESENT (LANDE, 1927). QUARTZ VEINS WITH PYRITE AND CHLORITE ARE COMMON IN THE AREA. |
| Deposit | SMALL SCALE PLACER MINING FOR GOLD SHOULD BE ECONOMICALLY FEASIBLE ALONG METAL CREEK SOUTH FROM PARADISE CREEK TO JUNCTION WITH GLACIER FORK. THIS AREA WAS PREVIOUSLY EXPLORED AND MINED BY DOUGLAS SUMNER AND JAMES ANDRULLI OF EAGLE RIVER, ALASKA. ABUNDANCE OF SCHEELITE IN CONCENTRATES IS ENOUGH TO WARRANT PROSPECTING OF THE AREA BETWEEN METAL CREEK AND GLACIER FORK (RICHTER, 1967). |
