TriStar Completes Third Phase Drilling Campaign at Castelo de Sonhos Intercepts of 29.30 m at 1.92 g/t gold and 12.85 m at 3.45 g/t gold Updates Metallurgical Testwork
Houston, TX / TNW-ACCESSWIRE / July 9 2014 / TriStar Gold Inc. (the Company) is pleased to announce the remaining and final results from the third phase diamond drilling program at the Company's Castelo de Sonhos Gold Project ("CDS") in the Tapajos region of Para state, Brazil. Results have been received for the last twenty nine (29) holes drilled at the Esperanca South target. In addition, two holes drilled by Barrick Gold in 1996 were added to the data-bank after they had been precisely re-located and were re-logged, re-sampled and re-assayed.
The third phase drilling program at CDS comprised 51 holes for a total of 4,110 meters. To date, 144 holes totalling 16,213 meters have been drilled at Castelo de Sonhos by TriStar. All drilling campaigns were conducted by Layne do Brasil Ltda.
Some holes (DH-95, 98,104,110 and 112), were re-entered and deepened when initial drilling bottomed in mineralization or when expected mineralized zones were missed. This deepening of the drill holes extended some of the mineralized zones with depth and located some of the missed mineralized zones.
Mark E Jones III, President and CEO of TriStar stated: "The current drilling at Esperanca South only focused on 2.75 km of the 16 km strike length of outcropping conglomerates associated with strong gold-in-soil anomaly and extensive old surface garimpeiro workings. We will continue our efforts to expand the mineralization along this trend as well as down-dip, to test for the presence of a larger mineralized basin. The positive metallurgy and good infrastructure in a free gold environment should provide a low cost setting."
The table below summarizes the most significant drilling intercepts from twenty nine new holes, two resampled Barrick holes and the new intervals from five deepened holes.

* Holes CSH-95 and CSH-119 bottomed in mineralization.
"These latest drilling results demonstrate that mineralized intercepts at CDS are as wide as 29 meters with some holes still bottoming in mineralization. In a number of holes, higher grade intervals have been intercepted as well as several multi-mineralized intervals. The more we drill, the more confident we are that Castelo de Sonhos may contain a significant mineralized system. Seventy seven (77) of the102 holes that were drilled at Esperanca South were positive and this attests to a good level of continuity of the mineralization at this target", Vice President of Exploration Elton Pereira said.
A 2,750 meter long zone of mineralization has been the subject of this drilling campaign at Esperanca South and along most of its length the final drilling sections are spaced 50 meters apart with drill holes spaced at 50 meters or less in each section.
The current drill program was designed to allow the Company to provide the necessary information to the Brazilian mining authorities for conversion of an exploration license to an exploitation license.
Preliminary metallurgical testing indicates promising high recovery rates. The test shows gravity recoveries of 73% and 88.6% for size fractions of respectively 80% passing 150 microns (100 mesh) and 80% passing 53 microns (270 mesh). Through cyanidation of the gravity rejects, the recovery was increased to 95.9% and 99.6% respectively for the two size fractions. Another test was performed on column cyanide leaching on 2 mm crushed samples with an average recovery of 78.7% which could indicate the possibility of recovery by heap leaching or vat leaching.
Castelo de Sonhos is a property where gold mineralization is hosted in proterozoic conglomerates and quartzites similar to those encountered at comparable gold deposits such as Jacobina in Northeastern Brazil and Tarkwa in Ghana (West Africa).
Sampling Procedures
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 and sent from the project site to the city of Parauapebas (Carajas), where SGS-Geosol Labs has a sample preparation facility.
All samples were dried at 60?C, 100% crushed to 95% minus 3mm and homogenized. A split of 1 Kg aliquot was taken and pulverized to 95% minus 150 mesh, from where a new split of 50g aliquot was taken to be analyzed by fire assay/atomic absorption.
The pulps were airfreighted to be assayed at SGS-Geosol lab in Vespasiano, Minas Gerais state. In addition to the laboratory quality control, TriStar has added its own certified standard check samples each 12 samples. The results of this checking demonstrated an acceptable quality on sampling preparation and analysis, without any contamination episode and with adequate precision and accuracy.
