The Catua property is a copper prospect in Jujuy Province, northwestern Argentina, 6 kilometres from the Chilean border and 220 kilometres northwest of the City of Salta. Access is by all-weather road.

The property comprises three cateos totaling approximately 9,000 hectares which were acquired by application. Mansfield was granted title on the original claim block in 2001 and an additional 400 hectare parcel, the Loj Loj property, was merged with Catua in 2003. The property was transferred to Pachamama in 2008 when Mansfield was restructured.

Copper oxides grading up to 20% copper occur within a clastic breccia which appears to have a vertically cylindrical footprint. The breccia body is emplaced into a regional fault zone. Copper minerals include copper wad, malachite, azurite and chryscolla. Breccia is also anomalous in lead, zinc, cobalt, arsenic and barium.
