Lillie

The Lillie is a molybdenum mine located in Alaska at an elevation of 499 feet.

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.

Comment (Deposit): SEE ALSO LILLIE PROSPECT AND SHAKAN MINE ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; USGS OPEN FILE 80-793, TABLE 1

Comment (Deposit): SEVERAL MINERAL DEPOSITS OCCUR NEAR THE CONTACT OF A CRETACEOUS QUARTZ MONZONITE PLUTON BORDERED BY CRETACEOUS MARBLE METAMORPHOSED FROM SILURIAN HECETA LIMESTONE (BREW, AND OTHERS, 1984); ALL THE DEPOSITS ARE PROBABLY RELATED TO THIS CONTACT ZONE. AT THE LILLIE PROSPECT (DENNY, 1961; HERREID AND KAUFMAN, 1964) A BAND OF TACTITE ABOUT 100 FEET WIDE IN DIORITE CONTAINS JOINT COATINGS AND DISSEMINATED IRREGULAR MASSES, LESS THAN A HALF-INCH IN DIAMETER, OF MOLYBDENITE AND SUBORDINATE POWELLITE, CHALCOPYRITE, PYRITE, AND MAGNETITE. AT ANOTHER UNNAMED OCCURRENCE, A BAND OF MAGNETITE ABOUT 3 FEET WIDE FOLLOWS THE CONTACT BETWEEN A DIORITE DIKE AND MARBLE. AT ANOTHER, SAMPLES OF HORNFELS, MARBLE, AND DIORITE COLLECTED FROM A DUMP OUTSIDE A SHORT CAVED ADIT CONTAIN VARIABLE AMOUNTS OF MAGNETITE, MOLYBDENITE, CHALCOPYRITE, PYRRHOTITE, PYRITE, AND GALENA. QUARTZ VEINS NEAR THE ADIT CONTAIN SCHEELITE AND A 5-FOOT CHIP SAMPLE OF THE VEIN CONTAINED 1.4% WO3. QUARTZ-RICH ROCK NEAR A

Comment (Location): PROSPECTS, OCCURRENCES, AND CLAIMS IN AN AREA OF SEVERAL SQUARE MILES ON NORTHERN KOSCIUSKO ISLAND, SOUTH OF DRY PASS. COORDINATES ARE FOR THE APPROXIMATE CENTER OF ACTIVITY. LOCALITY 50 AND 51 OF GRYBECK, BERG, AND KARL (1984).

Comment (Production): NONE

Comment (Deposit): MARBLE-DIORITE CONTACT ALSO CARRY DISSEMINATED SCHEELITE. THESE AND ADDITIONAL SHOWINGS OF MOLYBDENITE, PYRITE, AND CHALCOPYRITE IN THE CONTACT ZONE OF THE PLUTON SUGGEST THE POSSIBILITY OF A PORPHYRY COPPER OR MOLYBDENUM DEPOSIT AS WELL AS MORE CONTACT METAMORPHIC DEPOSITS IN THE VICINITY. ALSO SEE 'WORKINGS/EXPLORATION'.

Comment (Workings): OLD PROSPECTS AND OCCURRENCES ON WHICH LITTLE RECENT WORK APPARENTLY HAS BEEN DONE BEYOND MINOR SURFACE EXPLORATION AND A SHORT ADIT (SAID TO BE 100 FEET LONG). TWENTY-SEVEN LODE CLAIMS WERE STAKED IN THE AREA IN 1961 (U. S. BUREAU OF MINES, 1980) AND AN EVEN BIGGER BLOCK IS SHOWN ON THE 1995 ALASKA LAND STATUS MAP. EXTENT AND TYPE OF WORK DONE ON THESE CLAIMS IN RECENT YEARS IS UNKNOWN.
