Mariana’s objective is to increase value for shareholders by advancing discovery projects along the mineral resource development life cycle, focusing in Argentina and Chile.

The strategy entails:

• acquiring highly prospective land packages,
• exploration of these to potential discoveries,
• developing discoveries to robust projects.

In order to achieve this, the Company has a highly experienced management team with a successful track record in discovery through to resource development.

Furthermore management is deploying two experienced exploration teams focused in Santa Cruz Province, Argentina and Northern Chile.

Mariana’s exploration strategy has been successful to date with the following discoveries:

• an important new gold-silver discovery at its 100% owned Las Calandrias Project in late 2009,
• a silver-gold discovery at its 100% owned Sierra Blanca Project in 2008 and subsequent drilling campaigns.

The Company strategy in the short term is to confirm the extent and scale of the mineralisation at Las Calandrias and Sierra Blanca through follow up drilling.
