(TSX.V:GRK) (“Gray Rock” or the “Company”) is pleased to announce that a recently completed 1,000 metre diamond drill program on its Hot Bath porphyry copper-gold property in the Dease Lake area of northwestern British Columbia has successfully demonstrated the existence of an altered porphyritic hornblende-monzonite intrusive. The drill program was designed to test the porphyry intrusive hypothesis indicated by previous geological, geochemical and geophysical surveys which were previously announced on September 13, 2017. The property, located approximately 50km north of the Red Chris Project, comprises twelve mineral claims covering a total area of 3,993.097 hectares which were acquired by DeCoors in 2012, based on Geoscience BC’s Quest Northwest airborne magnetic geophysical survey, rock geochemistry and geological mapping study. The property was optioned to Gray Rock Resources Ltd. by DeCoors Mining Ltd. on June 19, 2017. The four test holes were sited on induced polarization targets with coincident copper and/or gold geochemical anomalies. Intersections of porphyritic textured, hornblende-monzonite intrusive rocks with potassium feldspar, hematite, magnetite and kaolinite group alteration in each of the four shallow drill holes, confirm an altered porphyry; the likely source for the geochemical and geophysical anomalies identified from exploration work by DeCoors in 2015 and 2016. The quartz-poor, plagioclase phyric, hornblende monzonite encountered in the drilling was variably altered by metasomatic potassium feldspar, illite-kaolinite-calcite and hematite, along with magnetite often in hairline fractures and replacing hornblende. Chlorite and epidote were also present in patches and seams. Fine, disseminated pyrite was ubiquitous throughout the core in all the holes and in sufficient quantity to explain the induced polarization anomalies. Figure 1 Red Porphyry with plagioclase phenocrysts Surface prospecting encountered several areas of copper oxide staining with malachite, bornite and azurite, along with blebs of chalcopyrite, in addition to the previously announced supergene copper-gold bearing quartz vein on the property. Work to date on the property identified porphyritic rocks that warrant further expl...
