TriStar Reports Partial Results of Diamond Drilling at Castelo de Sonhos Project

February 27, 2012

Houston, TX – TriStar Gold Inc. (the Company) is pleased to announce results now available from its initial 5,000 meter drilling campaign at the Company’s Castelo de Sonhos Gold Project in the Tapajos region of Para state, Brazil. These results come from twenty four (24) of a total of thirty three (33) diamond holes to be drilled on three different targets.

Up to now, thirty one (31) holes have been completed for a total of 4,963.15 meters. Of these, 17 holes (1,949.75 meters) are located at Esperança South target and 14 holes (3,013.40 meters) are located at Esperança Center target.

The main objectives of TriStar’s drilling program are: at Esperança South, to investigate a large (5,000 meters by 200 to 800 meters) soil anomaly along with a coincident 3,200 meter long zone of open cuts where local garimpeiros (artisanal miners) have been mining primary gold for the last 15 years and, at Esperança Center to investigate another large soil anomaly (2,500 meters by 800 meters). One (1) hole will be drilled to investigate an airborne geophysical anomaly, located at the western portion of the Esperança Center hill.

The table below shows the most significant results available for 24 holes of the current drilling at Castelo de Sonhos. All holes were drilled inclined from 45 to 55 degrees with the horizontal and planned to intercept mineralized layers at right angles. For holes 16 and 22, results are not complete yet.

Sampling Procedures

For holes 01 to 16 and 18, the recovered HQ and NQ size cores were split in half by a standard rock saw. One-half was sent to the laboratory in intervals not greater than 2 meters length and cut depending on geologic parameters. The remaining half-core was stored on site. The samples were bagged in lots of forty (40) samples and sent from the project site to Itaituba, where ACME Labs has a sample prep facility. Samples were dried at 60°C, 100% pulverized to 85% minus 150 mesh and 100% sieved in a 150 mesh sieve. The oversize was weighted and analyzed by fire assay/atomic absortion. The undersize was weighted, homogenized and an aliquot of 50g was split to be analyzed by fire assay/atomic absorption. Balance between weights and assays of the oversize and undersize resulted in sample’s final assay. For holes 17 and 19 to 24, the samples were dried at 60°C, 100% crushed to 85% minus 2mm, split in a 500g aliquot which was pulverized to 85% minus 200 mesh from where a new split of 50g aliquot was taken to be analyzed by fire assay/atomic absorption. For both types of preparation, the pulps were air freighted to be assayed at ACME Labs in Santiago, Chile. In addition to the laboratory quality control, TriStar has added its own certified standard check samples each 10 samples.
