Gold in Quartz
February 2016 by Chris Ralph. Most prospectors, when they think of hard rock gold deposits, think of quartz containing particles of gold. While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered ...

Panning for Gold in Ohio
Ross County. Located in the Appalachian region of Ohio, Ross County is home to about 70,000 people. Although prospecting didn't play a major role in the county's development, gold has been panned throughout its history. Most of Ross County's gold is fine placer. For this reason, many local prospectors choose to use a sluice box instead of …

The last reported gold production was from the Presidio mine in 1942. Graphite.
Gold Deposits in Metamorphic Rocks: What We Know and Why …
Historically, orogenic gold deposits were high-grade, with gold-bearing quartz-carbonate veins mined underground at 5 to >10 g/t. At higher gold prices, many deposits have produced much lower-grade open-pit ore from hydrothermally-altered rock that would have previously been considered waste, or just distal geochemical anomalies (i.e., <1 ...
Sovereign Gold Bonds (SGBs) Know Benefits & Why to Invest
SGBs offer a fixed interest rate of 2.5% per annum on the investment, which is credited to your account semi-annually.

Missouri Bill Would Take Steps Toward Treating Gold and Silver …
Missouri is already one of 41 states that do not levy sales tax on gold and silver bullion. Exempting the sale of bullion from capital gains taxes takes another step toward treating gold and silver as money instead of commodities.

How Gold Deposits Form
Lodes form through a process called mineralization – when gold is dissolved in hydrothermal fluids (ultra-hot, acidic ground water) that subsequently flow into the fissures/layers of pre-existing rocks where the gold re-solidifies to form a deposit. Native gold nuggets are an example of lode deposits. Intrusion-related deposits – similar to ...

Gold Prospecting in The USA
Kansas is a relatively poor state for prospecting. There is a small area in northeastern Kansas that was once covered by glaciers of past ice ages, and very fine glacial gold can be found. The Arkansas River and Smoky Hill River both drain some rich mining areas in Colorado. They do contain some fine gold as well.
