Granite Creek Copper Drills 127 meters of 0.85% Copper Equivalent and 4.6m of 7.51% Copper Equivalent at Carmacks/Carmacks North Project in Yukon, Canada

VANCOUVER, BC / ACCESSWIRE / February 11, 2021 / Granite Creek Copper Ltd. (TSXV:GCX)(OTC PINK:GCXXF) ("Granite Creek" or the "Company") announces complete assay results from its 2020 field exploration program at the recently consolidated, 176 square kilometre Carmacks copper-gold project in the high-grade Minto copper district of Canada's Yukon Territory. The Company completed 1,067 meters of diamond core drilling in five holes in an inaugural program with the dual objectives of advancing the Carmacks North (Formerly "Stu") Zone A target towards definition of a maiden mineral resource and expanding existing drill-defined sulphide mineralization at Zone 13 on the Carmacks deposit.

Highlights

• 127 metres of continuous copper mineralization, in drillhole CRM20-001, grading 0.85% copper equivalent ("CuEq") including28.65m of 1.74% Cu Eq and 19.2m of 1.19% CuEq (see table below) from Zone 13 in the Carmacks deposit.
• High-grade oxide mineralization at Carmacks North Zone A with STU20-003 intercepting 10.28 meters of 1.93% copper equivalent within a broader intercept of 25 meters of 1.27% CuEq (see table below).
• A 19.2-meter intersection of 0.104% Mo in CRM20-001 suggests potential for molybdenum to increase contained metal value.

Granite Creek President & CEO Tim Johnson stated, "We are very pleased with the success of our inaugural drill program on the recently combined Carmacks and Carmacks North project. The opportunity presented by the expansion potential of an already significant resource at Carmacks combined with the discovery potential at Carmacks North has positioned our shareholders with excellent exposure to the burgeoning copper bull market. I cannot thank and compliment our crews enough for their hard work and dedication to the project including the extra steps taken to ensure safety of all concerned in a very trying 2020 exploration season. We look forward to building on these results during an expanded 2021 program and will be relaying our plans to the public as they are finalized and confirmed."

Live Webinar

Granite Creek Copper will be hosting a live webinar event on Monday, February 15 at 8:00am PST / 11:00am EST during which Tim Johnson, President & CEO, will discuss the results and the Company's plans moving into Q2, including the upcoming 2021 exploration season. Click here to register.

2020 Drill Program

Granite Creek Copper's inaugural drill program intersected mineralization in all five holes, with assay results as follows:

Table 1 - Highlights from 2020 Diamond Drill Assays at the Carmacks/Carmacks North Project

1Copper equivalent (Cu Eq) values assume Cu $3/lb, Au $1800/oz, Ag $18/oz, Mo $10/lb and 100% recovery. *Weighted average intercepts shown. Estimated true widths vary but, based on geological interpretation of cross-sections, are estimated to be typically 60-70% of the intersected widths.

CARMACKS DEPOSIT - ZONE 13

The Carmacks Deposit contains 23.76(1) million tonnes of NI 43-101(2,3) compliant resources in the Measured and Indicated categories grading 0.85% Cu, 0.31 g/t Au, 3.14 g/t Ag, for contained metal of 446 Mlbs Cu, 237,000 ozs Au and 2.4M ozs Ag. Zone 13 is part of this resource but has not been drilled off and Granite Creek believes this zone has the potential to host substantial sulphide resources that can be added to the existing resource. A prime example is diamond drill hole CRM20-001, drilled behind previous drillholes and intersecting 127m of continuous, dominantly copper sulphide mineralization up to 80m down dip of previous intercepts and with the same tenor of mineralization (see Figure 1 below). With a known strike length of over 750m, and still open horizontally and at depth, Zone 13 is one of the prime targets for the 2021 exploration program.

CARMACKS NORTH - ZONE A

Drill intercepts in all three holes drilled at Zone A furthered the potential for delineation of both copper oxide and copper sulphide resources in the northern part of the claim block at Carmacks North. Formerly part of the Stu property, this zone was last drilled in 1980 and has seen little work until the company's inaugural program. Granite Creek relogged and reassayed selected holes from the 1980 program to assist the 3D modeling effort and will be releasing results once compiled and interpreted.

High-grade intercepts of 7.5% copper equivalent over 4.63 meters in hole STU20-002 and 1.9% copper equivalent over 10.28 meters in hole STU20-003 - both drilled at an offset to high-grade historical holes 80-09 and 80-14 - confirmed modeling work done by the Company (see Figure 2 below). 2021 exploration plans include deep penetrating geophysical surveys targeting underlying sulphide potential, trenching to confirm orientation of mineralization, and follow-up drilling.

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 analysed by igniting a 15 g sample followed by an aqua regia digestion with an ICP-MS finish.
