A type of hard, coarse mineral or conglomerate rock found in gold-bearing regions, especially in South Africa.
From Afrikaans 'banket,' possibly related to English 'banquet' due to the layered appearance of the rock, or derived from Dutch origins. The term is specific to mining geology.
Banket formations in South Africa contain some of the world's richest gold deposits—this humble-looking rock made the country incredibly wealthy.
