Sedimentary-rock hosted gold deposits in Nevada. All of the deposits shown that are north and east of the Battle Mountain-Eureka trend (and many of the others) are Carlin-type gold deposits . Source: USGS Goldstrike (Post–Betze) Mine , Carlin Trend , Nevada, the largest Carlin-type deposit in the world, containing more than 35,000,000 ounces ...
It was Canada's longest lived continuous mining operation and produced metals worth over $20 billion in terms of 2005 metal prices. Grading was in excess of 5% Pb and 6% Zn. The ore genesis of the Sullivan ore body is summarized by the following process: Sediments were deposited in an extensional second-order sedimentary basin during extension.
World-wide distribution of MVT deposits (red), clastic sediment-hosted (green), and unclassified (blue) lead-zinc deposits. Source: USGS. Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin.
There is a subclass of VMS deposits, the volcanic- and sediment-hosted massive sulfide (VSHMS) deposits, that do share characteristics that are hybrid between the VMS and SEDEX deposits. Notable examples of this class include the deposits of the Bathurst Mining Camp , New Brunswick , Canada (e.g., Brunswick #12); [ 5 ] the deposits of the ...
Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare-earth metals, although these accessories are typically subordinate to copper and gold in economic terms. Some examples include the Olympic Dam, South Australia, and Candelaria, Chile deposits.
[25] [46] The price of gold at a given time will have an impact on whether a deposit will be economically feasible. The economic viability of a deposit will also depend on the grade and tonnage of the reserves of a deposit, along with the costs associated with extracting the ore.
The genetic model of Kambalda-type Ni-Cu-(PGE) ore deposits is similar that of many other magmatic Ni-Cu-PGE ore deposits: Metal source: komatiitic magma, which has been generated by high-degree partial melting of the mantle and which was strongly undersaturated in sulfide in the source (Wendlandt, 1982; see also Mavrogenes and O'Neill, 1999)
Mineral commodities can be classified as metals or non-metals. [2] Metals refer to elements of the periodic table which include base, ferrous, minor fissionable and precious metals. On the other hand, non-metals refer to industrial minerals such as gypsum, diamonds, oil, coal and aggregate. Hydrothermal deposits of economically valuable and ...
