Granite Creek Copper Ltd. (TSX.V: GCX | OTCQB: GCXXF) (“Granite Creek” or the “Company”) is pleased to report positive metallurgical results in support of the upcoming  Preliminary Economic Assessment (“PEA“) for the Carmacks copper-gold-silver project (“the Project” or “Carmacks Project”) located in the Minto copper district, within the traditional territories of the Little Salmon Carmacks First Nation and the Selkirk First Nation, Yukon Canada, 

Metallurgical testing completed by SGS Vancouver Metallurgy (“SGS”) supports a simplified process consisting of froth flotation for the recovery of copper, gold and silver from both sulphide and oxide ores at Carmacks.  These tests demonstrate outstanding recovery levels and concentrate grades in both the sulphide only and blended sulphide/oxide samples, which would be utilized by the mine. Testing was done on samples consisting of material in which copper was present primarily in oxide minerals, where the copper was present as primarily sulphide minerals, and samples that were a blend of oxide and sulphide minerals.  Table 1 below highlights selected results from this testing:
    
Table 1 – Flotation Recovery and concentrate grade. .

1. Locked cycle flotation on blend sample consisting of 60% sulfide and 40% oxide.
2. The sulphide ore assayed 0.92% Cu, 0.67% S, and 0.24 g/t Au. Gold and copper head grades calculated from the flotation test assays agreed well with the direct head assays.
3. The oxide ore assayed, 0.60% Cu, 0.06% S, and 0.25-0.82 g/t Au indicating that nugget gold may exist. However, the gold head grade calculated from the flotation tests was consistently between 0.20 g/t to 0.23 g/t with an average of 0.21 g/t. Locked cycle testing was not completed on the oxide samples.

Test work produced a very clean, premium, high-grade concentrate that forms the metallurgical basis for the process flow sheet of the PEA, which the company expects to publish by the end of the current quarter. Flotation optimization and an economic evaluation of the target copper grade versus recovery has been recommended by SGS and will be considered in future test work.

President and CEO, Tim Johnson, stated, “Building on the success of sulphide flotation testing completed in 2021, this study directly supports the PEA allowing a simplified flow sheet consisting of well-established froth flotation technology to be considered for increased overall recoveries at the Carmacks Project. Metallurgy is a key component of the upcoming PEA and with this important work complete we look forward to delivering the updated study to the market within the current quarter.”

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 explora-tion 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, environ-mental 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 environmen-tal 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.
