Gold is hosted in vein stockworks and shear zones and although there is a clear spatial relationship between mineralisation and alteration, high vein density and well-developed foliations, the relationship is best defined statistically because the association between high gold grades and various combinations of these features is non-trivial.

Dolomite is a carbonate mineral composed of calcium magnesium carbonate CaMg (CO3)2. It is a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick. Dolomite is used as an ornamental stone, a concrete aggregate and as source of magnesium oxide.
For carbonaceous gold ore and its concentrates, gold extraction by direct cyanidation is usually low due to the known preg-robbing effect. The leaching behavior of a carbonaceous gold ore with a high content of dolomite in copper-ammonia-thiosulfate solutions was investigated.

Mineral resources are materials of economic interest found in or on the earth's crust in such quality, quantity and form that can be considered for economic extraction. In Nigeria, mineral resources play a great role in the economic sector.
Gold-rich pyrite formed by dissolution of dolomite and sulfidation of its contained Fe. Where dissolution and replacement were complete, ore-stage pyrite and other insoluble minerals were all that remained. Locally, these minerals accumulated as internal sediments in dissolution cavities to form ore with gold grades >400 g/t.
