Granite Creek Copper Launches Phase 3 of 2021 Drill Program at Carmacks Copper-Gold Project

VANCOUVER, BC / ACCESSWIRE / September 15, 2021 / Granite Creek Copper Ltd. (TSX.V:GCX)(OTCQB:GCXXF) ("Granite Creek" or the "Company") is pleased to announce the successful completion of Phase 2 of its 2021 drilling program, consisting of 20 holes of reverse circulation ("RC") drilling on Zones 2, 5 and 12 at the Carmacks deposit, as well as step-out drilling at Zone A in the Carmacks North target area. The Company has now launched the third and final phase of the 2021 drill campaign, returning to Zone 2000S at the Carmacks deposit to complete offsets of hole CRM21-011 where the Company intercepted a 105.52-meter interval of copper sulphide mineralization grading 1.18% CuEq (0.96% Cu, 0.01% Mo, 0.18 g/t Au, and 4.06 g/t Ag), including a high-grade intercept of 2.55% CuEq (2.17% Cu, 0.01% Mo, 0.36 g/t Au and 9.13 g/t Ag) over 21.22 meters (see news release dated August 24, 2021). The goal of Phase 3 is to continue to expand known resources and confirm the geometry in Zone 2000S to support the development of a mine plan for the sulphide portion of the deposit now underway by Sedgman and Mining Plus.

Granite Creek drilled 19 diamond core holes in the first phase of 2021 drilling, with assays from 9 holes released to date and results from the remaining 10 holes expected in the near term. Samples from the RC program have been sent for assay and will be announced over the next quarter as they become available.

Granite Creek President & CEO, Tim Johnson, commented, "We are very pleased with our 2021 exploration season to date and are excited to enter the final phase of drilling for the year. Given the very strong results we have seen from the first phase of diamond drilling and the positive implications we expect them to have for our resource expansion efforts, the Company adjusted the third phase to return to Zone 2000S where we see substantial opportunity to define additional new areas of mineralization outside the current resource model. Bringing this sulphide material into the model is expected to increase the current NI 43-101 mineral resource estimate in our planned update, with a view to a potentially significant extension of the projected mine life in an updated PEA for Q1 2022. We look forward to continued, substantive news flow throughout the remainder of the year and into 2022."

All statements in this release, other than statements of historical facts including, without limitation, statements regarding potential mineralization, historic production, estimation of mineral resources, the realization of mineral resource estimates, interpretation of prior exploration and potential exploration results, the timing and success of exploration activities generally, the timing and results of future resource estimates, permitting time lines, metal prices and currency exchange rates, availability of capital, government regulation of exploration operations, environmental risks, reclamation, title, and future plans and objectives of the company are forward-looking statements that involve various risks and uncertainties. Although Granite Creek Copper believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Forward-looking statements are based on a number of material factors and assumptions. Factors that could cause actual results to differ materially from those in forward-looking statements include failure to obtain necessary approvals, unsuccessful exploration results, changes in project parameters as plans continue to be refined, results of future resource estimates, future metal prices, availability of capital and financing on acceptable terms, general economic, market or business conditions, risks associated with regulatory changes, defects in title, availability of personnel, materials and equipment on a timely basis, accidents or equipment breakdowns, uninsured risks, delays in receiving government approvals, unanticipated environmental impacts on operations and costs to remedy same, and other exploration or other risks detailed herein and from time to time in the filings made by the companies with securities regulators. Readers are cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral exploration and development of mines is an inherently risky business.
