Summary:

The Yumpag area consists of a folded and thrust Mesozoic sedimentary basin, which is intruded by granodioritic, dioritic and subvolcanic stocks of rhyolite-dacite-diorite composition that generate an aureole of skarn and marble on the periphery.

Yumpag consists of a series of intermediate-sulfidation veins, running predominantly northeast, tensional to the Cachipampa fault, which controls the mineralization in the Uchucchacua Mine. The most important structure to date is the Camila vein, which presents a bonanza-type silver-bearing mineralization, associated with the presence of silver sulfosalts with some lead-zinc credits and traces of gold. The deposit is very similarto Uchucchacua, and will be integrated into said production unit in the future via a tunnel at level 3850.

The Yumpag area is an epithermal silver-manganese deposit hosted by Cretaceous limestone. Mineralization is structurally influenced by the Cachipampa fault, which also influences significant areas of silver mineralization at the Uchucchacua mine.

To date, two parallel mineralized structures with a N60° direction of significant economic interest have been identified: Camila and Tomasa.
