Land Status

Land ownership: National Forest
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Production): From merged and deleted record 1081503 (0560010088 and M045455): THE DATE FOR YEAR OF DISCOVERY IS APPROXIMATE. THE PRODUCTION FIGURES GIVEN ARE FOR THE TOTAL TIME OF PRODUCTION, 1900-1919, EVEN THOUGH THAT PRODUCTION WAS INTERMITTENT. IN 1918, THE MINE WAS CLOSED BY FIRE, BUT SEVERAL CARS OF ORE WERE SHIPPED IN 1919. PLATINUM WAS NOT DISCOVERED IN THE ORE UNTIL 1901.

Comment (Ownership): From merged and deleted record 1081503 (0560010088 and M045455): PERCENT OF OWNERSHIP UNKNOWN, BUT PROBABLY 100. NOT KNOWN IF MR. FOWLIE IS STILL THE OWNER AT PRESENT TIME.

Comment (Geology): From merged and deleted record 1081503 (0560010088 and M045455): ONLY THE MORE IMPORTANT ORE MINERALS ARE LISTED. OTHER MINERALS PRESENT INCLUDE CHALCOTRYCHITE, ATACAMITE, CHALCANTHITE, PYRRHOTITE, LORANDITE, ORPIMENT, REALGAR, PYRITE, MARCASITE, MAGNETITE, PENTLANDITE, SPHALERITE, MACKINAWITE, ELECTRUM, GOETHITE, LIMONITE, JASPEROID, VILLAMANINITE, DIGENITE, VIOLARITE, MERENSKYITE, MICHENORITE, KOTULSKITE, RHODIAN SPERRYLITE, MOLYBDENITE, AND MALACONITE. TEN PT AND PD MINERALS HAVE BEEN IDENTIFIED IN THE ORE, EIGHT OF THEM BISMUTHO-TELLURIDES OR TELLURIDES.

Comment (Geology): From merged and deleted record 1081503 (0560010088 and M045455): THE DIORITE AND GABBRO LISTED IN THE LR DATA SET ARE ACTUALLY METADIORITE AND METAGABBRO.

Comment (Workings): Blanche shaft, 600-700 yards (meters) west of the New Rambler Mine was an exploration shaft developed to find the western extent of the New Rambler ore body. It was sunk to a depth of 160 ft. At 120 ft. it penetrated a zone of low-grade copper mineralization. (PIC-32, p. 39).

Comment (Deposit): From merged and deleted record 1081503 (0560010088 and M045455): THIS DATA SET IS INCLUDED ONLY FOR THE PURPOSE OF DESCRIBING THE ORE GEOMETRY AS IT EXISTED AT THE TIME OF PRODUCTION. THIS DATA DOES NOT IMPLY THE EXISTENCE OF ANY RESERVES AT THE PRESENT TIME. TYPE OF ORE BODY- THE ORE WAS LOCATED IN THREE SMALL PODS THAT WERE STRUCTURALLY CONTROLLED EITHER BY FISSURES OR BY THE INTERSECTION OF A MYLONITE ZONE WITH TWO DISTINCT SHEAR ZONES, DEPENDING ON THE PUBLISHED SOURCE. EARLY BELIEF WAS THAT THE DEPOSIT WAS OF THE FISSURE VEIN TYPE, BUT LATER STUDY SUGGESTS THAT THE ORE WAS LOCATED IN MAFIC BLOCKS THAT WERE TECTONICALLY TRANSLATED PROJECTIONS OF THE MULLEN CREEK LAYERED MAFIC INTRUSIVE COMPLEX. THESE BLOCKS WERE LOCATED AT THE INTERSECTION OF A NORTHEAST- TRENDING MYLONITE ZONE WITH AN EAST-WEST MILE-WIDE ZONE OF INTENSELY SHEARED ROCKS AND WITH A SET OF FOUR CLOSE- SPACED NORTHWEST-TRENDING FRACTURES. DEGREE OF WALL ROCK ALTERATION- VARIABLE FROM SLIGHT TO INTENSE. DIMENSIONS OF THE THREE ORE BODIES WERE SIMILAR. DIMENSIONS GIVEN ARE AVERAGES OF THE DIMENSIONS OF THE THREE INDIVIDUAL BODIES.

Comment (Development): PT DISCOVERED IN 1901

Comment (Location): NEAR THE HEAD OF DOUGLAS CREEK JUST EAST OF THE CARBON-ALBANY COUNTY LINE. IN MEDICINE BOW NATIONAL FOREST

Comment (Reserve-Resource): SYSTEMATIC GEOLOGICALLY GUIDED EXPLORATION IN THIS PROVINCE HAS REASONABLE PROBABILITY OF DISCOVERING AN ORE DEPOSIT

Comment (Production): 7,000 TONS ORE SHIPPED; 4,000 TONS WERE PRODUCED AT 25-30% CU. BY 1906 MORE THAN $120,000 WORTH OF COPPER AND PLATINUM ORE HAD BEEN MINED FROM NEW RAMBLER. HIGH-GRADE ORE AVERAGED 2.41 OZ/TON PD, 0.12 OZ/TON PT. IT IS THOUGHT THAT DEPOSIT IS MINED OUT

Comment (Commodity): CR, V, TI, CO, ZN, TE, AND BI HAVE ALSO BEEN REPORTED

Comment (Workings): NONE OF THE MINES IN THE NEW RAMBLER DISTRICT ACCESSIBLE TODAY. (All are on private property, but none are posted to keep out).

Comment (Deposit): RECORD W032390 HAS BEEN MERGED AND DELETED.

Comment (Geology): AREA IS COVERED BY GLACIAL DEBRIS. HOST ROCKS ARE THE PROBABLE SOURCE OF PLATINUM METALS. TEMPERATURES OF FORMATION WERE PROBABLY BETWEEN 300 AND 340 DEGREES C.

Comment (Deposit): INTERSECTION OF NW AND NE TRENDING MINERALIZED SHEAR ZONES. ORES WERE NEAR SURFACE, OXIDIZED, GOLD BEARING. AT 65 FT ENCOUNTERED SUPERGENE COPPER ORE WITH PLATINUM-GROUP METALS. HYPOGENE ORE WAS NEVER MINED. DIMENSIONS ARE OF LARGEST POD. DEPOSIT CONTAINED THREE SMALL ORE BODIES; UNPUBLISHED MODEL NAME: NEW RAMBLER CU-AU-PGE.

Comment (Orebody): Information from consolidated and then deleted record 10181503: Length 13 m; Width 9 m; Depth to top 25 M; Thickness 9 m. Type of Orebody #1: Other Shape of Orebody #1: Irregular Primary mode of origin: Hydrothermal Primary Ore control: Faulting Secondary Ore control: Fracturing Type of Wallrock Alter. #1: Propylitic Type of Wallrock Alter. #2: Silicification Type of Wallrock Alter. #3: Sericitic Minimum depth to Top: 15 (units not specified) Date of Last modification: 810129

Comment (Location): Site is now in the yard of a vacation cabin amid a well established and growing cabin/second home community. The workings have been long since abandoned.
