Veins and Hydrothermal Deposits Geology In

Hypothermal deposits are formed at great depths and high pressures and temperatures.Temperatures may range from 300° to 500° Celsius during the formation of such deposits. Casseterite, wolframite and molybdenum veins; gold-quartz veins; copper-tourmaline veins; and lead-tourmaline veins provide examples of mineral associations which may occur in hypothermal deposits.

Molybdenum Wikipedia

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of

The study found that, in a basecase scenario with a molybdenum price of US$20 per lb. and assuming debt and equity financing split equally, the Chu project carries a net present value (NPV) of $1.04 billion if TTM buys all new equipment for the mine. The NPV increases to $1.44 billion if the equipment purchased is used.
