VANCOUVER, BC – April 11, 2008 – Mirasol Resources Ltd. (TSX-V: MRZ; Frankfurt: M8R) is pleased to announce high grade gold results from its wholly-owned Curva project, located in the prolific Deseado Massif of Santa Cruz Province, southern Argentina. At Curva, Mirasol has discovered multiple surface gold occurrences hosted in quartz vein structures and breccias.
Initial exploration identified five (5) distinct areas of gold -silver mineralization across the property which have been mapped and sampled.
The Curva property covers 169.5 square kilometres of prospective Jurassic-age volcanic units and older basement rocks which are partly covered by a thin veneer of younger gravels. Gold-silver mineralized quartz veins and breccias are exposed over a series of low hills, and elsewhere in windows of Jurassic volcanic rocks exposed through the gravel cover.
The principal target identified to date, Cerro Arthur, returned anomalous gold assays from all rock chip vein samples taken (Table 1), including peak assays of 9.5, 10.3, 13.2 and 22.1 g/t gold. At Cerro Arthur, mineralization occurs in three trends of 15 to 70 centimetre wide epithermal quartz veins, which are traceable for up to 160 metres to the edge of gravel cover. Vein material shows well-developed epithermal textures, and commonly includes amethyst, typically associated with mineralization in low sulphidation gold-silver systems.

Mirasol’s in-house geophysical team has initiated detailed ground magnetic and IP/resistivity surveys at Cerro Arthur. The surveys are designed to identify prospective structures, especially where they pass under shallow gravels. Preliminary results show strong resistive IP responses which correspond to mapped veins, and moreover, the results show a series of resistive trends that may represent additional covered veins. The Company has expanded the survey area to explore a large, gravel-covered structural corridor, highlighted by ground magnetics, that could host extensions of the Cerro Arthur veining.
The Curva Project has excellent access with the provincial highway passing through the claims. Mirasol’s management is pleased with the results to date at the Curva project, and the ongoing success of its project generation efforts in Santa Cruz. The continuing exploration success reported by Mirasol and other explorers demonstrates that Santa Cruz Province remains underexplored, and that the Deseado Massif may develop into an emerging world class epithermal gold-silver province.

Surface Geochemical Sampling: All assay results reported herein are for rock and stream sediment samples collected from surface; assay results from drill core samples may be higher, lower or similar to results obtained from surface samples.
Quality Assurance/Quality Control: Exploration at Mirasol’s Projects is supervised by Mirasol’s Exploration Manager, Timothy Heenan, and Principal Geologist, Paul Lhotka, both qualified persons under NI 43-101. All technical information for the Company’s projects is obtained and reported under a formal quality assurance and quality control (QA/QC) program. Rock chip and stream sediment samples are collected under the supervision of Company geologists in accordance with standard industry practice. Samples are dispatched via commercial transport to an ISO 9001:2000-accredited laboratory in Mendoza, Argentina for analysis. Results are routinely examined by an independent geochemist to ensure laboratory performance meets required standards.
