The Serra das Éguas district is also known in the literature as the Brumado district (Cassedanne & Cassedanne 1978). It is a large hilly area (approx. 5 x 15 km2) with several magnesite (& talc) pits around Brumado. One of the world's largest magnesite deposits is located in this district.

The Pomba pit is above the Pedra Preta open pit mine further up the hill/mountain (Rock Currier information, based in 1988 field trip).
