TriStar Gold Presents Update On Drilling At Castelo De Sonhos Project

At the Castelo de Sonhos gold project of TriStar Gold Inc. (the “Company” or “TriStar”), a drilling program is underway that is designed to provide confirmation of the assumptions used to determine the exploration target range presented in the Company’s 43-101 Technical Report filed on SEDAR in March 2016. Specifically, the step-out drilling will increase knowledge of geometry (the folding of the conglomerate band), continuity of mineralization and trends in grade and thickness. Since this information may affect investors’ decisions, Tri Star intends to provide monthly updates on the drilling program.

Two core rigs are on site and have been drilling since mid-September in the Esperanca South area. Initially, they will complete a series of six step-out holes (Figures 1 and 2) that test the exploration target model’s assumption that mineralization extends significantly beyond the last drill holes on the southwest limb. By the end of September, the first of these holes, CSH-l6-l44, was completed and the second, CSl-l-l6-l45, had reached approximately half of its planned depth.

Mr. Nick Appleyard, President and CEO, commented: “We’re off to a good start with the drilling. The first completed hole supports our View that the mineralization does continue along strike to the southwest. As we drill the 40om step-out holes to the southwest, we anticipate that we can extend Esperanca South by two kilometres or more. Then we’ll test the northern extension of Esperanca Center, followed by in-fill holes to support the estimation of an updated resource.”

As shown in Figure 3, CSH-l 6-144 was drilled with the intention of intersecting the down-dip extension of one of the many locations where there are three separate sources of evidence of strong mineralization at surface: the outcrop of the conglomeratic band, a strong geochemical gold anomaly in the soil, and hand- dug workings from historical small-scale mining activity. This hole was also designed to test the base of the overlying arenite because the two nearest holes (CSH-12-044 and CSH-12-085), approximately 20om to the northeast along the strike of the conglomerates, each encountered several meters of strong gold mineralization above 5 g/t in the arenite, immediately above the conglomerates. Since the exploration target range assessment assigned no potential to the overlying arenite, CSH-l 6-144 will assist in determining if there is additional resource potential in this unit. The deeper parts of CSH-l6-l44 are intended to test the along-strike continuity of conglomerate-hosted mineralization encountered in CSH-11-020.

Preliminary logging of the two new drill holes shows the expected sequence of lithologies, supporting that the exploration target’s model of the 3D geometry of the conglomerate band is accurate at these locations.

In October, the core from the first holes will be halved, photographed and logged in detail; Vz-core samples from these holes will be sent for analysis, with assay results expected by the end of October. During the next month, sample material for a 125 kg sample will be composited from core for the metallurgical testwork that will be needed for the preliminary economic assessment report planned for the third quarter of 2017.
