Deposit | The Buckingham stockwork molybdenum system is classified as a low-fluorine (or quartz monzonite) molybdenum system by Theodore and Menzie (1984). It contains one of the largest identified resources of molybdenum in the United States, estimated at more than 1 billion tonnes of mineralized rock averaging approximately 0.06 weight percent molybdenite (MoS2) and containing 100 million ounces of silver as well as smaller amounts of tungsten, copper, and gold. Molybdenum mineralization is related to emplacement of a late Cretaceous (86-Ma) composite porphyry system that intruded and metamorphosed the surrounding Late Cambrian Harmony Formation to biotite hornfels. Approximately half of the Buckingham deposit is hosted by metamorphosed and intensely veined rocks of the Late Cambrian Harmony Formation and half by intrusive rocks (Doebrich and Theodore, 1996). Molybdenum mineralization is related to the emplacement of a late Cretaceous composite quartz monzonite porphyry system that intruded and strongly metamorphosed the enclosing Paleozoic sedimentary rocks to hornfels. There are at least seven major phases of intrusions that collectively form what are called the East and West stocks. All seven phases contain molybdenum mineralization. The main Buckingham deposit formed in association with five igneous phases located in the two stocks. All five phases developed shells of molybdenite mineralization and the shells locally overlap to produce grades of about 0.1 to 0.20 weight percent MoS2. Porphyry copper deposits in the copper zone surrounding the central molybdenum zone underwent supergene enrichment to create the Contention, Carissa, Copper Queen, Widow, and Sweet Marie copper deposits. Gold-silver skarn ore at the Surprise Mine and distal disseminated silver-gold ore associated with silica-pyrite alteration at the Empire Mine (approximately 1.5 million tonnes averaging 1.8 g Au/t) and at the Northern Lights Mine (approximately 390,000 tonnes averaging 1.6 g Au/t) may be associated genetically with the Buckingham system. There appears to be metal zoning from proximal copper-rich ores in the Contention Pit to the distal gold-silver-copper ores in the Surprise Mine (Doebrich and Theodore, 1996). |
