Hope Creek

The Hope Creek is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): BEDROCK EXPOSURE IS RARE IN THE HOPE CREEK AREA, EXCEPT ON RIDGETOPS, AND LOCALLY ALONG CREEKS. MICACEOUS QUARTZITE, TYPICALLY WEATHERING TO MASSIVE SLABS AND BLOCKS, IS THE MOST ABUNDANT RUBBLE AND FORMS MOST OF THE BEDROCK OUTCROPS. WHITE, SULFIDE-FREE, QUARTZ LENSES, SEGREGATIONS AND VEINLETS ARE COMMON IN THE QUARTZITE. QUARTZ-MICA SCHIST AND PELITIC SCHIST ALSO FORM SOME OUTCROPS. NONFOLIATED HORNBLENDE QUARTZ MONZONITE OCCURS AS SMALL BODIES IN HOPE CREEK DRAINAGE. THE ROCK VARIES IN COMPOSITION BETWEEN QUARTZ MONZONITE AND MONZOGRANITE. HORNBLENDE QUARTZ MONZONITE IS COMMONLY ALTERED TO CHLORITE-ANKERITE-SERICITE WITH OR WITHOUT PYRITE. FLUORITE AND GARNET ARE OCCASIONALLY PRESENT. ALTERATION OCCURS BOTH ALONG PLUTONIC CONTACTS AND ALONG SHEAR ZONES WITHIN THE PLUTONS. NUMEROUS COBBLES AND BOULDERS OF SULFIDE-BEARING HORNFELS OCCUR IN HOPE CREEK. SAMPLES OF SULFIDE-BEARING HORNFELS AND QUARTZ-MONZONITE NORTH OF HOPE CREEK ARE STRONGLY ANOMALOUS IN AS (UP TO 7,000 PPM)

Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.

Comment (Workings): PLACER GOLD WAS DISCOVERED IN THE EARLY 1900'S BUT WAS NEVER MINED EXTENSIVELY (MENZIE AND OTHERS, 1983, P. 46).

Comment (Location): THE LOCATION IS THE APPROXIMATE CENTER OF MINING ACTIVITY ALONG HOPE CREEK. MINING ACTIVITY OCCURRED AT SEVERAL LOCATIONS ALONG THE CREEK, SPECIFICALLY AT 65.40 N, 146.32 W AND 65.40 N , 146.36 W. HOPE CREEK IS A TRIBUTARY TO FAITH CREEK.

Comment (Deposit): AND AU (UP TO 550 PPB) AND MODERATELY ANOMALOUS IN SB (UP TO 120 PPB). SULFIDE-BEARING HORNFELS AND QUARTZ MONZONITE SAMPLES FROM SOUTH OF HOPE CREEK ARE ALSO ANOMALOUS IN THESE ELEMENTS WITH MAXIMUM VALUES OF 53 PPM AS, 43 PPB AU, AND 29 PPB SB. VIRTUALLY NO MINERALIZATION WAS OBSERVED IN METAMORPHIC ROCKS AWAY FROM PLUTONIC CONTACTS. IN SUMMARY, SULFIDE-BEARING HORNFELS AND ALTERED QUARTZ MONZONITE SAMPLES NEAR HORNBLENDE QUARTZ MONZONITE CONTACTS ARE THE MOST GOLD-RICH ROCKS FOUND IN THE HOPE CREEK DRAINAGE. (SWAINBANK AND BURTON, 1987, P. 6-19 TO 6-22) PLACER GOLD WAS FOUND IN STREAM GRAVEL, APPARENTLY IN SUBECONOMIC AMOUNTS. STIBNITE DEPOSITS WERE REPORTEDLY FOUND IN 1926, BUT WERE APPARENTLY REBURIED BY 1942 (JOESTING, 1943, P. 12).
