Identification information

Deposit ID 10310422
MRDS ID M231672
Record type Site
Current site name Longstreet Gold Project
Alternate or previous names Pi?on Gold Project, Longstreet Gold-Silver Project

Comments on the site identification

  • This record covers an area which encompasses the historic Longstreet Mine (current Main Zone of mineralization) as well as a surrounding larger area of mineralized targets. The historic Longstreet mine is described by MRDS record # M231672 from which all pertinent material has been incorporated into the current record. The earlier record could be deleted.

  • Type of workings Underground
    Length 777.24M

Comments on the workings information

  • Old workings consist of two adits and a shaft, with recent drilling

Comments on other economic factors

  • Mine Development Associates (MDA) of Sparks, Nevada reported a measured resource of 3,277,900 tonnes of mineralization grading 0.82 g/t Au and 19.5 g/t Ag.
    1989 drill-indicated reserves were reported as 4 Mt grading 0.024 opt Au in the Main zone and a total geologic resource of 9.6 Mt grading, 0.024 opt Au, which nicludes a North zone and a Rim zone.
    Past production was 1 Kt of $10 ore in 1930 from the historic workings.

Comments on development

  • The Longstreet Mine was discovered prior to 1929 at which time a 100-ton cyanide mill was built on the property. 1000 tons of $10 ore was milled in 1930. IN 1951, the property was under lease to John N. Richardson of Alameda, CA. Golden Lion Mining Co. and Naneco Minerals, Ltd. had interests in the property in the 1990s. Exploration interest in the area increased with the discovery of the Midway property 18 miles west. In 2002, Rare Earth Metals Corp. announced plans to acquire Golden Crown Resource?s option on the Pi?on
    property held by MinQuest Inc., a Nevada-based mineral exploration and property acquisition company. A mapping program was carried out at Pi?on during the summer of 2002, and a property valuation report to verify published reserve and resource was prepared. In early 2004, Rare Earth Metals Corp. announced the results of the initial phase of exploratory drilling at the Longstreet Gold-Silver Project. The company has an option to acquire a 100% interest in the Longstreet property. This first program was designed to verify the extent and continuity of the mineral resource referred to as the Main Zone, first mined in the 1920s, and calculated in a 1988 preliminary feasibility study by Mine Development Associates (MDA) of Sparks, Nevada. The MDA study reported a measured resource of 3,277,900 tonnes of mineralization grading 0.82 g/t Au and 19.5 g/t Ag
    The phase 1 drill holes were oriented to intersect the two sheeted-vein set structures which host the mineralization. The drilling program was successful in demonstrating the continuity of mineralization. The holes intercepted oxidized gold-silver mineralization where projected from previous drilling. The intervals reported similar to greater grades over similar to greater widths. The strike and down-dip extent of mineralization will be tested in the spring when weather permits.

General comments

Subject category Comment text
Deposit The mineralized area consists of 7 separate gold-silver target zones. Four of the prospective zones including the Main Zone" are heap-leach, open-pit targets hosting oxidized sheeted-vein gold-silver mineralization. The remaining three zones are deeper, "bonanza" style, high-grade underground drill targets. Seven independent mineralizing sources, and seven areas of sheeted veining associated with major shear zones have been identified on the project with coexisting gold anomalies.
