Free gold in quartz veins comes in all sizes, with a full range of gold particles from obvious stuff easily visible to the eye down to gold that can barely be seen with a magnifying glass. The coarser stuff can be found with a metal detector, while the smaller sized gold requires that the rock be crushed and the resulting powder panned.

Computed mineral percentage in a quartz-carbonate-adularia vein district for the production of gold, copper i tungsten, arsenic, lead, zinc and beryllium. It was supported cording to the Gold Hill Standard in 1917, the mill was in operation for 23 months during the years 1892-1895.
The US Geological Survey ranked Montana as number 7 in gold production in the US and reported that the state included 31 gold mining districts. Total gold production from the 19th century to 1968 was 17.8 million ounces, but considerable amounts of gold have been mined since (Bergendahl and Koshmann, 1968).
At the Culpeper Mine, located 2 miles east of Richardsonville, gold-bearing pyrite is found in a massive quartz vein that is up to 30 feet in width, enclosed in quartz-sericite schist mapped as the Chopawamsic Formation. The mine was worked intermittently between 1836 and 1905, and at least two shafts were sunk to depths of about 100 feet.

Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP.
Production figures for the district in the 1880s and 1890s are not known but total recorded production from 1902 to 1965 for the combined Vipond Park and Quartz Hill area was 57,261 tons of ore which yielded 1,118 ounces of gold, 1,024,485 ounces of silver, 198,991 pounds of copper, 72,032 pounds of lead and 500 pounds of zinc, most of which came from the West Lone Pine mine (Geach 1972).

Gold Hill, in Grass Valley, California, was the site of one of the first discoveries of quartz gold in California. While quartz gold was also found in other areas of Nevada County, California during the same time, it is this find near Wolf Creek that led to quartz-mining frenzy and subsequent creation of the Gold Country quartz-mining industry. The location is honored as a California

Estimating Soviet Gold Production, Richard Flynn. The USSR has long maintained a veil of strict, unbroken secrecy on domestic production of gold. The State Secrets Decree of 1947, amended in 1958, forbids disclosure of data on the quantity of gold produced, plan goals, production capacity of plants, and the size of gold deposits. To help ensure a reticent attitude among knowledgeable Soviet
