TriStar Discovers Significant New Gold Reefs at Castelo de Sonhos

SCOTTSDALE, AZ--(Marketwired - August 01, 2017) - Assay results from reverse circulation (RC) drilling at the Castelo de Sonhos (CDS) gold project of TriStar Gold Inc. (the "Company" or "TriStar") (TSX VENTURE: TSG) continue to show significant intervals in new holes. "We're glad that the new drilling is consistent with our exploration target concept," says Nick Appleyard, TriStar's President and CEO. "We've known since last year that we've got considerable potential for growing the resources along the strike of the mineralized conglomerate. But the July results from in-fill holes in the heart of Esperança South now demonstrate significant upside potential even in areas where indicated resources were previously reported. Thick intervals running well above the deposit average point to potential additional resources beyond the pit shell that constrained the 2014 resource."
