Guess where the gold mine with the largest reserves is located?

Uzbekistan! (Where the heck is that?) Best of luck trying to invest there! Newmont apparantly operates part of the waste dump!

Muruntau Gold Deposit

"The Muruntau gold deposit which produces 1.6 million ounces from an open pit and another 400,000 ounces from treatment of the waste dump material is perhaps the largest gold deposit in the world. Reserves now stand at 1000 mt at 3.5 g/t gold - a truly massive 4000 tonnes of gold. Larry Drew and Byron Berger have authored a comprehensive review of the geology in Ore Geology Reviews. I take the liberty of quoting Byron Berger in a recent email on the genesis of the deposit:

In our interpretation, Muruntau is a mesozonal deposit formed in an extensional stepover (dilational jog) along the northwesterly striking left-lateral Sangruntau-Tamdytau shear zone. The step appears to have been forced by motion on the northeast-striking Daugyztau-Muruntau shear zone. The vast majority of the tonnage is in small to microveinlets that are controlled by schistocity, axial plane cleavage, transposed cleavage, and "flat" fractures. The mineralization is upper Carboniferous to lower Permian, but the isoclinal folding and related schistocity are due to older Paleozoic deformation. More through-going "Mother Lode" type veins contain a significant proportion of the contained gold and are later stage of mineralization. The veining is crack-seal in origin and ductile deformation of early stage veins is evident."
