The goldbearing ore, located in both the bedding planes of the shale and the diorite, is found in conjunction with iron oxides, pyrite, and chalcopyrite (Pardee and Schrader 1933). There was little work done in the drainage after 1904, with only 1921 production rating a mention in the annual statistics.
In, ores generation got a HUGE changes, as part of "new geology". In this guide i explain where you can find ores.
double refractory ore has been achieved at Nordgold''s Suzdal mine in Kazakhstan which treats double refractory ore with both visible and invisible gold hosted in sulphide associations of pyrite and arsenopyrite and also, carbonaceous black shale. Following extensive laboratory and demonstration scale testing of the Outotec

The origin of fluid involved in black shale gold deposits is an ongoing controversy. Many researchers insisted that ore fluids of orogenic gold deposits are of metamorphic origin (Groves et al., 1998, Kerrich and Cassidy, 1994, McCuaig and Kerrich, 1998, Phillips and Powell, 2010).

Pregrobbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter. In case of certain ores, gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction from occurring.

Gold is a raw material found in Shale and Sandstone Outcrops. It is a highly conductive metal that is used in electronics and computer manufacturing. Gold can also be found as a large resource deposit. Said large deposits are especially plentiful in the Jellyshroom Caves and Lost River. Single pieces of raw gold can be found on walls and the ground in the Inactive Lava Zone.
Shale is a finegrained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments (siltsized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility.

Shale is a finegrained sedimentary rock that forms from the compaction of silt and claysize mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated.
