VANCOUVER - Granite Creek Copper Ltd. is pleased to announce that it has retained SGS to complete an updated Preliminary Economic Assessment ('PEA') on the Carmacks project.

The PEA will use the 2022 Resource Estimate, consisting of 36.2 million tonnes (Mt) in Measured and Indicated categories (M&I), grading 1.07% CuEq (0.81% Cu, 0.26g/t Au, 3.23g/t Ag and 0.011% Mo) for a total of 651 million pounds (Mlbs) of contained M&I copper and an additional 38 Mlbs Cu Inferred as the main input. Building off a 2017 PEA(1), the updated study will encompass the following: Significant Increase in Contained Copper - The 2022 resource estimate marked a 43% increase in contained copper over the previous estimate referenced(2)

Inclusion of Sulphide Processing - As of the publication of the 2022 resource estimate the Carmacks project consists of roughly 50/50 sulfide and oxide resources by contained metal. The Company sees the inclusion of sulphide resources as a significant potential value driver having a positive impact on the economics of the project and High Proportion of Resources Modeled in Three Conceptual Open Pits - 96% of the 2022 resources are contained within the conceptual pits. With a high percentage of current resources reporting in conceptual pits the cash cost per pound of copper is expected to be significantly lower when compared to a similar sized underground operation.

Timothy Johnson, Granite Creek President & CEO, stated, 'The launch of the updated Preliminary Economic Assessment study marks a major milestone in the development of the Carmacks deposit at a time when commodities demand is seeing rapid growth. The Carmacks project is well-positioned by its location, access to infrastructure, and proximity to the operating, high-grade Minto mine just to the north. Both copper and molybdenum have been deemed by the Canadian government to be 'critical minerals' based on their role in the transition to a low-carbon economy which we expect will provide prolonged price strength well into the future. We look forward to continuing to bring positive news as we develop this high-grade copper project.'

Forward-Looking Statements

This news release includes certain statements that may be deemed 'forward-looking statements'. 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. Accordingly, the actual events may differ materially from those projected in the forward-looking statements.
