The Casa de Pedra mine is located some 55 km to the south of the centre of Belo Horizonte and 110 km south-west of the Itabira Mine Complex.

For detail of the regional setting, geology and stratigraphy of the host sequence and district see the Quadrilatero Ferrifero Iron Province

The deposit is developed on high grade ore within the Cauê Itabirite of the Minas Supergroup Itabira Formation. It is located near the southern margin of the tight, complex, thrust bounded and reclined Moeda Synform which has been influenced by at least four deformational events, near where it wraps around the basement Bação Complex and changes trend from north-south to ESE to become the Dom Bosco Synform.

The mine is owned by Cia. Siderurgica Nacional (CSN), the largest integrated steel maker in South America, and is that company's main source of ore for its steel works, with any excess production being taken by CVRD. The mine has a nominal capacity of 12.7 Mt of ore per annum, although in 2001 it produced a total of 7.16 Mt, 25% of which was lump ore, the remainder being mainly sinter feed.

The most recent source geological information used to prepare this summary was dated: 2002.
