VANCOUVER, BC — June 12, 2007 — Mirasol Resources Ltd. (TSXV:MRZ Frankfurt: M8R) is pleased to announce the acquisition of the Rubi copper-gold property, located on the prospective Paleocene-age porphyry and epithermal belt of Northern Chile.

The Paleocene metallogenic belt has a proven pedigree for producing large copper porphyry and epithermal gold deposits exemplified by BHP Billiton’s Spence project (3.5 Mt copper) and Meridian Gold’s El Penon mine (3.8 M oz. gold; 63 M oz. silver).

The Rubi claims, covering 73 square kilometres, were staked as a result of the company’s new Tertiary Generative Program, announced March 5, 2007. Completed reconnaissance exploration includes stream and rock geochemical sampling, regional mapping and PIMA analysis of the prospect area.

The prospect is defined by an extensive, advanced argillically-altered outcrop, interpreted to be a lithocap, which is exposed through a gravel plain. Exotic copper minerals are locally seen in the gravels and in prospect pits surrounding the outcrop area, and narrow gold-base metal veins crop out at the northern edge of the gravel cover. Mirasol’s geologists believe that this setting is prospective for porphyry copper (and accessory gold-molybdenum) style mineralization.

Due to its low altitude and favourable access, the Rubi property can be worked year round and rapidly advanced to drill stage. Mirasol has identified two zones within the Rubi project area that merit further exploration.
