Since the 1930s, the Cadillac, Malartic, and Val d’Or (French for – “Valley of Gold”) camps produced more than 45 million ounces of gold, and are presently home to seven producing gold mines. Mining in the region experienced a resurgence between 2000 and 2010 when two companies, Osisko Mining and Detour Gold, began investing heavily in two areas: Malartic and Detour Lake.
Because they typically do not have heavy-duty equipment, artisanal miners tend to dig many shallow holes across large swaths of land. They extract and process gold at the site and then move onto the next area. They usually do not refill holes after extractions. And they often use mercury to remove gold from sediments, which can lead to serious health problems and long-term water and soil contamination.
Multiple shallow holes planned Multiple shallow holes are planned in the upper part of the southern end of the Tuvatu lode system utilising the company’s shallow capacity drills.
Fosterville South Chief Executive Officer, Rex Motton, states, “The core drilling component of this program, now underway, is targeting what we believe is the section with potential for high gold grades. To now have multiple holes in the scout drilling program return high-grades of gold near surface within a newly identified area to the north now adds another dimension to Golden Mountain.
In gold mining, 10 g/t is a high-grade deposit for gold. 1 g/t is a low grade that shows the area is not very densely populated with gold. But it all depends on the price of gold.
Success shown upon NovaGold in the 2001 drilling program. Either through great skill or great luck, they struck significant amounts of gold in 41 of 42 drill holes. In fact, most of the holes showed ore grades which would be considered extraordinary all by themselves much less as part of a 41 hole string of extraordinary holes.
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead.It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt ...
Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome, where gold and other precious ...
How gold is mined depends on the deposits. Lode deposits are concentrations of gold found in solid rock. If the gold-bearing rock is located at the earth's surface, the mining company will use open-pit techniques. First, miners drill a pattern of holes, which they then fill with explosives.
