9.1.3: Mineral Deposits, Ore Deposits, and Mining
Mining, the Environment, and Politics; A mineral deposit is a place in Earth’s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true.

Precious Metal Mining in Colorado Articles Colorado
1. 2. From the 1850s to the 1920s, gold and silver mining drove Colorado’s economy, making it into an urbanized, industrial state. The rapid development of Colorado’s mineral resources had political, social, and environmental consequences. The mining of gold and silver in Colorado began in earnest during the Colorado Gold Rush of 1858–59.In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.Artisanal and Small-Scale Gold Mining Without Mercury

The stock to flow will climb to 52, which is much closer to gold. The following halving, in 2024, will raise that number to 113 and remember gold has stock to flow of "only" 62 and it does not have halving events. Now contrast Bitcoin's dynamic stock-to-flow with Gold's, who's stock-to-flow of 62 is not likely in increase.Hardrock mining involves uncovering and extracting non-fuel metal and mineral deposits of solid ores or eroded deposits in streambeds.
