Mirasol Reports Discovery of a New High Grade Silver Vein, Santa Cruz,
Argentina

VANCOUVER , Jan. 6 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R) is pleased to announce the discovery of a new high-grade silver vein, the Julia vein, part of the Virginia vein zone located on a 100% Mirasol-owned mineral property within the Area of Special Interest for Mining in Santa Cruz province, Argentina , where mining development is permitted and four precious metal mines are in operation.

The Julia vein was discovered while following up alteration and structural targets during November 2009 . There are no indications that it had ever been previously prospected or sampled. Assay results are available for the Julia Vein , but remain pending for other nearby vein structures found subsequently (Figure 1).

Initially, thirty rock chip samples from outcrop, subcrop and float of the Julia vein were collected and returned silver values of between 21.9 and 2,660 grams per tonne (g/t) silver. Gold values range from (less than) 0.01 to 0.14 g/t (Table 1). The average silver grade of the initial 30 samples is 645 g/t (18.8 troy ounces per short ton), but sampling indicates that segments of the vein may contain higher silver grades, perhaps over 1,000 g/t silver. Further exploration will be required to determine what the average grade of the vein may be and if there are higher grade shoots within it.

The Julia vein is traceable over a length of greater than 2,000 metres in outcrop, subcrop and as large float blocks, and displays changes in azimuth as well as probable vein splits or splays. The wall rock to the vein is rarely exposed. The width of the Julia vein appears to range from under one metre to at least 5 metres, but lack of wall rock exposure and early stage of exploration do not permit an average width to be determined.

Julia is an epithermal quartz vein with very high silver to gold ratios. Two principal vein textures have been observed: multi-phase banded vein, which typically forms along the vein's margin, and breccia vein comprising fragments of vein material and lesser wall rock, hosted in an iron oxide and silica rich matrix. Both vein styles are silver-bearing. Quartz textures include chalcedonic, saccaroidal, crystalline and comb quartz with open spaces present. Iron and manganese oxides are abundant at surface, and sulphides are rarely present except for galena in a few cases.

Subsequent exploration in December, 2009, by Mirasol geologists included saw channel sampling of the Julia vein with geological mapping at 1:50 scale of the channels, mapping at 1:2,000 scale of the vein, and further prospecting. During the prospecting work, new outcropping and subcropping veins were discovered and sampled. The Naty and Margarita veins display textures very similar to the banded vein and breccia vein material of the Julia Vein , while the Ely veins mainly comprise breccia vein material. A total of 283 rock samples (including control samples) were collected during the work described above with assays results pending.
