VANCOUVER, BC / ACCESSWIRE / January 10, 2023 / Granite Creek Copper Ltd. (TSXV: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.

温哥華,BC/ACCESSWIRE/2023年1月10日/Granite Creek銅業有限公司(TSXV:GCX|OTCQB:GCXXF)("花崗巖溪“或”公司“)高興地報告了積極的冶金結果,以支持即將進行的Carmack銅-金-銀項目(”項目“或”Carmack項目“)的初步經濟評估(”PEA“),該項目位於加拿大育空地區Minto銅區的小鮭魚Carmack First Nation和Selkirk Firk Firk Nation的傳統領地內。

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:

SGS温哥華冶金公司(“SGS”)完成的冶金測試支持一種簡化的流程,即從Carmack的硫化物和氧化物礦石中回收銅、金和銀。這些測試顯示,該礦將利用的純硫化物和混合硫化物/氧化物樣品的回收率和精礦品位都很突出。測試的樣品包括銅主要以氧化物礦物形式存在的材料,銅主要以硫化物礦物形式存在,以及氧化物和硫化物礦物的混合物樣品。下面的表1突出顯示了此次測試的選定結果:

  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.
  1. 60%硫化物和40%氧化物組成的混合樣品的閉合循環浮選。
  2. 硫化礦石中銅含量為0.92%,硫含量為0.67%,金含量為0.24g/t。根據浮選試驗計算出的金、銅頭品位與直接頭分析結果吻合較好。
  3. 氧化礦中銅含量為0.60%,硫含量為0.06%,金含量為0.25~0.82g/t,表明可能存在金塊金礦化。然而,浮選試驗計算出的金頭品位始終在0.20~0.23g/t之間,平均為0.21g/t。沒有對氧化物樣品進行鎖定循環試驗。

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.

測試工作產生了非常清潔、優質、高品位的精礦,構成了PEA工藝流程圖的冶金基礎,該公司預計將在本季度末公佈該流程圖。SGS已建議進行浮選優化和目標銅品位與回收率的經濟評估,並將在未來的試驗工作中加以考慮。

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."

總裁兼首席執行官蒂姆·約翰遜表示:“基於2021年完成的硫化物浮選測試的成功,這項研究直接支持了PEA,允許考慮使用由成熟的泡沫浮選技術組成的簡化流程圖,以提高Carmack項目的整體回收率。冶金是即將到來的PEA的關鍵組成部分,隨着這項重要工作的完成,我們期待着在本季度內向市場交付最新的研究報告。”

Forward-Looking Statements

前瞻性陳述

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.
