Granite Creek Copper Reports Final Results 2021 Drill Program, Including 120.65m at 0.94% Copper Equivalent, at the Carmacks Copper-Gold-Silver Project in Yukon, Canada

VANCOUVER, BC / ACCESSWIRE / March 10, 2022 / Granite Creek Copper Ltd. (TSX.V:GCX | OTCQB:GCXXF) (“Granite Creek” or the “Company“) is pleased to announce the final assay results from the Company’s Phase 2 Reverse circulation (“RC”) and Phase 3 diamond drill programs at the 100%-owned Carmacks project.

Live Webinar

Granite Creek Copper will be hosting a live webinar on Thursday, March 17 at 10am PT (1pm ET), during which President & CEO, Timothy Johnson will be joined by Project Geologist, Jacob Longridge, for a comprehensive update on the Company’s Carmacks copper-gold silver project, including Q&A.

The objective of the Phase 2 RC program was early-stage evaluation of additional targets adjacent to known zones as well as step-out drilling at Carmacks Norths’ Zone A area. The program was successful in identifying mineralization in 13 of 20 holes with several areas prioritized for follow-up diamond drilling in the 2022 field season. The Phase 3 diamond program was targeted at confirming the geometry in Zone 2000S, complementing hole CRM21-011 which intercepted 105 m of 1.18% Copper Equivalent (“CuEq”) (0.96% Cu, 0.01% Mo, 0.18 g/t Au, and 4.06 g/t Ag) (see news release dated August 24, 2021). Additional drilling was conducted in the central portion of Zone 13 to further upgrade resources in this zone (Figure 1).

Granite Creek President & CEO, Tim Johnson, commented, “We are extremely pleased with the results of our 2021 exploration program which achieved all of our objectives and exceeded our expectations in several important respects. We expanded sulfide mineralization in three of the main zones at Carmacks which will be reflected in an updated NI 43-101 resource estimate, followed by a new mine plan which is being developed to incorporate both oxide and sulfide material. We anticipate the sulfide resources could make a significant difference to the mine life and economics of the Carmacks deposit and we look forward to further defining that potential.”

The results of Phase 3 have highlighted the predictable geometry of zone 2000S (see Figure 2). Both drillholes intersected mineralization well below the current sulphide resource1,2, with drill hole CRM21-023 intersecting mineralization approximately 120 meters below the base of the inferred sulphide resource and extending through to approximately 230 m below the base of the current inferred sulphide resource. Two holes drilled in Zone 13 continue to highlight the potential of this zone with CRM21-025 intercepting 120.65 m grading 0.76% Cu, 0.016% Mo, 0.14 g/t Au, 2.53g/t Ag or 0.94% CuEq. These 2021 drill campaign results will be incorporated into an updated National Instrument 43-101 resource estimate being prepared by SGS Canada.

The phase 2 RC drilling was conducted in Zones 2, 5, 12 at Carmacks and Zone A at Carmacks North. The purpose of the program was to test zones peripheral to the deposit and find targets for follow up with the diamond drill. The program was most successful in Zone 5 where 4 of 4 holes intersected mineralization and, consequently, Zone 5 will be a priority for drilling in 2022. The program was also successful in Zone 12 where it was used to trace and test mineralization on the west side of the zone that is not included in the 2016 resource estimate. Six of seven holes in zone 12 intersected mineralization. At Zone 2, mineralization was intersected in 2 of 6 holes.

At Zone A, the drill was used to test geophysical targets, but the program was cut short due to drilling difficulties. One of the 3 holes intersected mineralization but the other two did not reach target depth due to difficult drilling conditions.

Quality Control and Quality Assurance

Quality assurance and quality control procedures include the systematic insertion of duplicate, blank and standard samples, making up 12% of the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and shipped directly to the Bureau Veritas preparation laboratory in Whitehorse. All geochemical analyses were performed by Bureau Veritas in Vancouver. Copper and silver analysis was performed by four-acid digestion with an ICP-ES finish. Non-sulphide copper was determined through a sulphuric acid leach with an AAS finish. Gold was analyzed by igniting a 15 g sample followed by an aqua regia digestion with an ICP-MS finish.
