ABSTRACT:(Scottsdale, AZ), TriStar Gold Inc. (the “Company” or “TriStar”) has received from CSA Global (“CSA”) an independent mineral resource estimate for the Castelo de Sonhos gold project. “We are very pleased to see the predictions of the exploration target range now being validated by hard data. This resource uses all the available data on the project, however 30% of the assays from the now completed RC program are still outstanding and we have not yet started to test Esperança West or East,” says Nick Appleyard, TriStar’s President and CEO, “we are looking forward to updating the resource soon and completing the technical and economic studies that will support the preliminary economic assessment.” The new RC drilling also allows the resource block model to extend to 120m below surface, approximately 50m deeper than the previous block model. With the assays available by August 2017, resources were not estimated in gaps in Esperança South and Center where drill hole spacing exceeds 100m; and resources have not yet been estimated in Esperança East and West, where drilling is planned for 2018. All resources to a depth of 120m below the ground surface, inside the conglomerate band, and inside the green region shown in Figure 1 were classified as Inferred; no resources were classified as Measured or Indicated. Current open pit operations in similar paleo-placer projects such as the Tarkwa mine of Gold Fields show that resources down to 120m below surface have reasonable prospects for eventual economic extraction. The resources classified as Indicated in 2014 have been reclassified as Inferred, pending implementation of CSA’s recommendation for collection of a suite of samples for determination of dry bulk density.
