Golden Ridge Resources Ltd. (TSX-V: GLDN) is very pleased to announce a new alkalic Cu-Au porphyry discovery at its Williams Zone prospect, located on the Company’s Hank project in BC’s golden triangle. HNK-18-001 intersected a broad interval of vein and disseminated Cu-Au-Ag mineralization, centered on a strongly potassic altered monzonite intrusion. The newly discovered alkalic porphyry system is characterized by bornite-chalcopyrite+/-digenite mineralized monzonite, intruding strong potassic altered intermediate to mafic Stuhini volcanics hosting veined chalcopyrite and minor bornite mineralization. The steeply dipping tabular monzonite intrusion has now been intersected in all four holes drilled in the Williams Zone, indicating a strike of at least 200 metres. The Hydracore 2000 drills currently being utilized on the Property have a maximum working depth of approximately 600 meters. The latest hole completed in the Williams Zone, HNK-18-007, ended in mineralized monzonite at 603.50 meters depth. Mineralization appears to increase at depth. The system remains open along strike in both directions and at depth. Assay results will be released as they are received. Photographs of mineralized intercepts from HNK-18-001, for which assays have been received, as well as Williams Zone holes two and three (HNK-18-002 and HNK-18-005), for which assays are still pending, have been posted to the Company’s website. A drilling plan view map (Figure 1) and cross-section (Figure 2) are presented below and have also been posted to the Company’s website.

Chris Paul, Vice President of Exploration for Golden Ridge, commented: “The size and grade of the Williams Zone discovery are remarkable. Broad intervals of intense potassic alteration with bornite and digenite indicate the presence of a large alkalic Cu-Au porphyry system at surface. Indications are that only the top of the system has been intersected, including the presence of widespread phyllic (aka quartz-sericite-pyrite) alteration at surface, which typically overlies porphyry Cu-Au systems, and exists both above and lateral to the potassic altered monzonite at Williams. Copper mineralization also extends for a considerable distance into the surrounding volcanic rocks, while the mineralized monzonite shows good continuity along strike and at depth. The initial magnetic survey conducted in 2017 suggested a circular zone, 400 meters in diameter. It is now apparent that the mineralization forms a broad tabular zone extending beyond at least the northern limit of the magnetic anomaly. The actual cause of the circular magnetic anomaly remains unknown at this time, but is possibly a result of magnetite alteration overlying a feeder stock at depth. We are very excited to continue testing the extensions of the system both along strike and at depth.”
IP Geophysical Survey on Williams Zone:
Two 3.0 km long IP lines, run on 250-meter centers across the Williams Zone have now been completed. Processing of the field data is ongoing and preliminary results reveal a 0.8 km wide chargeability anomaly, coincident with the ground magnetic anomaly at surface in the Williams Zone. The chargeability anomaly plunges to the south, toward the Property’s lower alteration zone (LAZ) and expands to over 1.6 km in width. Initial interpretations suggest that the quartz-sericite-carbonate-pyrite alteration constituting the LAZ may represent a large alteration halo overlying the southern extension of the Williams Cu-Au porphyry. The target remains open to the south, north and at depth, off the IP grid. Additional lines are currently being planned.

Quality assurance/quality control procedures:
All drill core was logged, photographed, cut and sampled by Golden Ridge personnel. Prior to shipment to MS Analytical’s sample preparation facility in Terrace, B.C., certified reference material standards, blanks and field duplicates were inserted at a ratio of approximately one in every 20 drill core samples. Samples were prepared in Terrace by crushing the entire sample to 70 per cent passing minus two millimetres, riffle splitting off one kilogram and pulverizing the split to better than 85 per cent passing 75 microns. After preparation in Terrace, the prepared pulps were shipped to MS Analytical’s analytical laboratory in North Vancouver, B.C. The gold assays are determined by FAS-111 fire assay method which reports results in parts per million (equivalent to grams per tonne). Any samples with a fire assay that report gold concentrations equal to or higher than 10.0 g/t Au are analyzed by metallic screen method (Au-SCR24).
Base metal assays are determined by IMS-230 4-acid digestion with ICP-AES/MS finish method, which reports results as parts per million (ppm). All analyses that reach the overlimit of IMS-230 are reanalyzed with an ore-grade method. The analytical results are verified with the application of industry-standard quality control and quality assurance procedures.
Exploration activities at the Hank Property are being supervised by Wade Barnes, the Company’s Project Geologist and a Qualified Person as defined by National Instrument 43-101. Wade Barnes is a PGeo registered with the Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) and has verified the data, reviewed and approved this news release.
