TriStar Starts Drilling and Airborne Geophysics at Castelo de Sonhos Property in Brazil and Confirms Soil Gold Anomaly

September 15, 2011

HOUSTON, TX - TriStar Gold Inc. (the Company) is pleased to announce that the company has started its drilling campaign as well as an airborne geophysical survey at its 100% owned Castelo de Sonhos property in Southwestern Pará State, Brazil.

The first phase of the drilling campaign, to be performed by Layne-Christensen do Brasil Ltda., will comprise a minimum of 5,000 meters of core drilling, to cover the two main targets at Castelo de Sonhos project, the Esperança Center and Esperança South geochemical anomalies. Drilling at Esperança Center started with one drill rig in the first week of September. A second drill rig is scheduled to start drilling at Esperança South in the second half of September.

An airborne geophysical survey (magnetometry and radiometry), is being performed by FugroLasa Brasil, which will cover a total of 7,019 linear kilometers in two contiguous blocks covering the entire mineral rights area. The main block covers the Castelo de Sonhos plateau with flight lines spaced 100 meters apart for a total of 5,228 linear kilometers. The second block covers the remaining eastern area with flight lines spaced 200 meters apart for a total of 1,791 linear kilometers. The surveys will be flown at an elevation of 100 meters.

TriStar’s soil geochemistry sampling program for the Esperança South target has confirmed the previous results obtained by Barrick Gold in 1995-1996 as did the program conducted at Esperança Center (See New Release dated August 9, 2011). The TriStar soil sampling programs are designed to cover and fill in both Esperança targets and to extend sampling to areas not previously sampled. As in the two targets the main anomalies run in the same North-South trend, the sampling lines run East-West, on 100 meter centers (Barrick’s sampling was centered at 200 meters) and samples were collected every 50 meters.

As for Esperança Center, the preparation method was to sieve the samples at 230# and for the analysis the method was Fire Assay with Atomic Absorption finishing in 50 g aliquot.

Acme Laboratories performed the preparation and analysis of all samples, executing the preparation in Itaituba-Pará, at its local preparation facility and the analysis in Santiago,Chile. Approximately 5% of the samples consist of QA/QC samples inserted by Tristar into the batches, as two types of standards, blanks and duplicates. Satisfactory results were obtained for all tests.

Of a total of 1,422 soil samples at Esperança South, 526 samples (37%) returned assays equal to or higher than 100 ppb (parts per billion) gold and 187 samples (13%) returned assays higher than 250 ppb gold. The average gold value was 121 ppb and the maximum gold assay was 1,384 ppb (1.38 grams per tonne). The 100 ppb gold curve defined two main anomalies. One anomaly, very continuous and consistent, is 2,000 meters long by 800 meters wide, striking in a NNW direction and the other, less continuous, is 3,000 meters long by 400 meters wide, striking in a NE direction. On a combined basis, the anomalies at Esperança South and Esperança Center have a total length of 7,500 meters.

Mark E. Jones, President and CEO of TriStar stated, “Our sampling program has now confirmed the presence of two large anomalies at Esperanca South: one at 2,000 by 800 meters and the other at 3,000 by 400 meters. These two anomalies are in addition to the main anomaly at Esperança Center, announced on August 9, 2011. Our sampling has also confirmed the previous work conducted by Barrick. With drilling now underway, we will provide additional updates of results as they become available”.

Mr. Rodrigo Mello, a qualified person as defined in NI 43-101, has read and approved the technical portions of this release.
