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 (Workings): KNOWN YEARS OF ACTIVITY ARE 1925, 1953, 1954 AND 1969 THROUGH 1982 (MENZIE AND OTHERS, 1983, P. 51).

Comment (Deposit): HEADWATERS OF PTARMIGAN CREEK ARE ON THE SOUTH SLOPES OF PORCUPINE DOME. BEDROCK UNDERLYING PTARMIGAN CREEK IS THE UPPER QUARTZITE AND UPPER SCHIST UNITS MAPPED BY WILTSE AND OTHERS (1995). THE UPPER QUARTZITE CONSISTS OF PORPHYROBLASTIC-ALBITE-CHLORITE-MUSCOVITE-QUARTZ SCHIST, QUARTZITES AND MICACEOUS QUARTZITES. THE UPPER SCHIST IS A MIXED UNIT DOMINATED BY VARIABLY GARNETIFEROUS, PELITIC QUARTZ-MUSCOVITE SCHIST, MUSCOVITE-QUARTZ SCHIST AND CHLORITE-QUARTZ-MUSCOVITE SCHIST WITH DISTINCT INTERVALS OF GARNETIFEROUS CALCAREOUS ALBITE-PORPHYROBLASTIC MUSCOVITE-CHLORITE SCHIST. SEDIMENTS ARE SAID TO CONTAIN LARGE AMOUNTS OF COPPER (BURAND, 1965). GOLD CAN BE READILY PANNED FROM THE THIN VENEER OF GRAVELS ON THE BEDROCK IN PTARMIGAN CREEK JUST UPSTREAM FROM ITS JUNCTION WITH EAGLE CREEK (LAMPRIGHT, 1996, P. 75). KNOWN YEARS OF ACTIVITY ARE 1925, 1953, 1954 AND 1969 THROUGH 1982 (MENZIE AND OTHERS, 1983, P. 51).

Comment (Location): PTARMIGAN CREEK IS A TRIBUTARY OF BIRCH CREEK. IT FLOWS SOUTH FROM PORCUPINE DOME AND CROSSES THE STEESE HIGHWAY IN THE NW1/4 NE1/4 SEC. 17, T. 7 N., R. 11 E.

Comment (Exploration): Status = Inactive
