The primary mining method is longitudinal retreat long-hole stoping. Ore is hauled by truck to the Kremzar mill located approximately 0.8 kilometres from the portal of the ramp. The Phase 3+ expansion of the operation to 2,400 tpd is expected to be completed in 2026.
Cerro Vanguardia operates a single tailings dam. The state road GO-337 passes close to the operation, providing access for logistics. Power for the mine is supplied and purchased in the open market. Three mining methods are used for underground mining: sub-level stoping (bottom-up and top-down), cut and fill, and room and pillar. A brief history

Gold production reached a level of 110 kg per month during the tailings treatment years from 1995 to 2007. To date in excess of 1 million ounces of gold have been produced from the property. On April 1, 2006 a wholly-owned subsidiary of Caledonia Mining Corporation completed the purchase of the Blanket Mine from Kinross.
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, …
Kidd Creek was discovered in 1963 and witnessed the start of open-pit operation in 1966, while underground production was started in 1972. The mine is operated with three shafts using blast hole stoping with cemented backfill. The ore is sent to the Kidd Creek Metallurgical Division at Hoyle, located 27km south-east, for processing.

Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.. Shaft sinking is one of the most difficult of all mine development methods: restricted space, …

Placer mining / ˈ p l æ s ər / is the mining of stream bed deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment.. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and …
Method of underground mining operation: Sublevel StopingBy courtesy of Tamrock - SandvickCopyright
In sublevel stoping (a form of open stoping), ore chutes, manway, and "starting raises" must be put up and one or more drifts driven on each sublevel (fig. 60, B). In sublevel caving and top-slicing, raises are put up at …
Tonight I tweaked it to our preferred spice level using extra red curry paste, a little curry powder, 1/3 of a jalapeño and a pinch cayenne. I also try to incorporate as many veggies as possible so I added assorted peppers, broccoli, extra onion and spinach and I shoestring cut the carrots, I have a texture issue with grated carrots.
Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed. A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam. Random House dictionary says the origin of the …
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams.This process is considered to be safer compared to underground mining because the coal seams are accessed from above …
