2010 Work Program Initiated at Rio Grande Cu-Au Project 

VANCOUVER, BC - Pachamama Resources Ltd. with its joint venture partner, Antares Minerals Inc. reported the initiation of the 2010 work program at their 50-50 owned Rio Grande project. Rio Grande is a large copper-gold system with porphyry affinities located in Salta Province, northwestern Argentina. Drilling to date comprises a total of 33,015 metres in 78 diamond drill holes. The proposed program will include work to characterize the metallurgy over a range of mineralization types with varying degrees of oxidation. Pachamama and Antares believe that sufficient drilling has been completed to calculate an initial resource for the deposit once this metallurgical program has been completed. Mineralization at Rio Grande remains open to depth in several zones.

As operator, Antares plans to contract a geophysical consulting firm to complete a deep looking Titan IP/Resistivity survey with the objective of characterizing the entire system and defining additional drill targets. This geophysical survey is scheduled to commence upon crew availability with an estimated start date of September 2010. In addition, the parties plan follow-up soil geochemical surveying and geological mapping on the Northeast Zone where previous work has partially defined copper-gold-zinc mineralization which has similarities to the weaker mineralized areas on the outer fringes of the Mansfield Minerals Inc.'s Lindero heap leachable gold deposit, located 7 kilometres to the southeast. John M. Leask, President and CEO said, "We are pleased to resume work at Rio Grande where drilling and trenching to date has established extensive copper-gold mineralization over a four sq. kilometer area. At least four higher grade feeder type areas have been partially delineated. The gross metal budget indicated to date is impressive, as are many of the stronger mineralized intercepts. Recently drilled molybdenum mineralization under the Sofia Zone also requires follow-up testing."
