Deposit type

  • Porphyry
  • Vein / narrow vein

Summary:

The CuMo deposit is a porphyry type deposit and has been classified as a porphyry copper molybdenum deposit (Klein, 2004; Spanski, 2004), or as a porphyry molybdenum-copper (low fluorine type) deposit (Mutchler et al, 1999).

The CuMo deposit is primarily of economic interest for its Mo content but contains significant values of Cu and Ag. Low-grade zones of copper enrichment typically form above and partially overlap with molybdenum shells in porphyry molybdenum deposits (Carten et al, 1993). The CuMo deposit is classified as a porphyry Mo-Cu deposit (Mo greater than 0.04% and Cu being potentially economically significant).

The CuMo deposit is typical of large, dispersed, low-grade molybdenum ± copper deposits. These systems are associated with hybrid magmas typified by fluorine-poor, differentiated monzogranite igneous complexes, characteristic of continental arc terranes. Due to their larger size, the total contained potentially economic molybdenum in these types of deposits can be equivalent to or exceed that of high-grade molybdenum deposits such as Henderson or Climax (Carten et al, 1993).

Molybdenum mineralization was discovered at CuMo in 1963. The only other molybdenum showing in Boise County is the Little Falls molybdenum prospect, which is situated just to the northeast of CuMo.

Mineralization on the property occurs in veins and veinlets developed within various intrusive bodies. Molybdenite occurs within quartz veins, veinlets and vein stockworks. Individual veinlets vary in size from tiny fractures to veinlets five centimeters in width, with an overall thickness averaging 0.3-0.4 cm. Pyrite and/or chalcopyrite are commonly associated with molybdenite although molybdenite can occur alone without other metallic mineralization.

Chalcopyrite occurs in quartz-pyrite + molybdenite veinlets, in magnetite + pyrite as well as in pyritebiotite + quartz + magnetite veins with secondary biotite halos. Scheelite is common on the property and closely parallels the distribution of molybdenite (Baker, 1983).
