VANCOUVER, BC, Feb. 29, 2024 /CNW/ - Panoro Minerals Ltd. (TSXV: PML) (Lima: PML) (Frankfurt: PZM) ("Panoro", the "Company") is pleased to announce the filing of the NI-43-101 Technical Report for the updated Mineral Resource Statement for the 100% owned Cotabambas Project in Peru.  The results of the mineral resource estimate were announced on the January 15, 2024 press release.  The technical report was authored by AGP Mining Consultants Inc.  The report is available at the Company's Website and on SEDAR.

The updated mineral resources at 0.15% CuEq cutoff grade include:

  • An Indicated mineral resource of 507.3 million tonnes at 0.34%Cu, 0.20 g/t Au, 2.42 g/t Ag and 0.0021%Mo, and 0.43%CuEq grade.

Mineral Resource Statement

The Mineral Resources for the Cotabambas deposit are reported by copper equivalent cut-off grade of 0.15 %CuEq within an optimized pit constraint. The effective date of the Mineral Resources is 20 November 2023.

The principal metals grades were estimated by the ordinary kriging interpolation method on capped composite copper, gold, silver and molybdenum grades.  No recoveries have been applied to the interpolated in-situ estimated grades.

Tables 1 and 2 present the mineral resources by domain for Indicated and Inferred mineral resources, respectively, within the optimized pit constraint.

Note: Base case in bold. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Summation errors may occur due to rounding. Open pit mineral resources are reported within optimized constraining shell. Reported open pit cut-off grade is 0.15%CuEq. Breakeven open pit cut-off grade is 0.07% CuEq. Mineral Resources have an effective date of November 20, 2023.  The Qualified Person responsible for this resource statement is Paul Daigle, P.Geo. (APGO, 1592). . Copper equivalent ( CuEq) is calculated using the equations: Oxide: CuEq = Cu + 0.4126*Au + 0.0038*Ag + 0.000*Mo; Mixed: CuEq = Cu + 0.5819*Au + 0.0063*Ag + 0.0003*Mo; Supergene: CuEq = Cu + 0.4498*Au + 0.0054*Ag + 0.0002*Mo; and Hypogene: CuEq = Cu + 0.4373*Au+0.0053*Ag+0.0002*Mo, based on the differentials of long range metal prices net of selling costs and metallurgical recoveries for gold and copper and silver. Metal prices for the CuEq formulas are: US$ 4.25/lb Cu, US$ 1,850 /Oz Au; US$ 23.00 /Oz Ag; and US$ 20.00 /lb Mo. Metal recoveries for the CuEq formulas are for Oxide: 0.0% Cu, 65% Au, 48% Ag, and 0.0% Mo; for Mixed: 60% Cu, 55% Au, 48% Ag, 40% Mo; for Supergene: 87.5% Cu, 62% Au, 60.4% Ag, 40% Mo; and for Hypogene: 90% Cu, 62% Au, 60.4% Ag and 40% Mo. Capping of grades varied between 0.50 %Cu and 3.7%Cu, 0.33 g/t Au and 2.3 g/t Au, and between 0.029%Mo and 0.060%Mo; on 6m composites by domain. The density varies between 2.20 g/cm3 and 2.66 g/cm3. Mineralization would be mined from open pit and treated using conventional flotation. Rounding in accordance with reporting guidelines may result in summation differences. *Oxide Cu - amenable to leaching; Oxide Cu-Au amenable to blending with sulphides (Au >0.25 g/t).

  • risks relating to potential challenges to Panoro's or its partners' right to explore or develop projects

  • risks relating to mineral resource estimates being based on interpretations and assumptions which may result in less mineral production under actual circumstances

  • risks relating to Panoro's or its partners' operations being subject to environmental and remediation requirements, which may increase the cost of doing business and restrict operations

  • risks relating to being adversely affected by environmental, safety and regulatory risks, including increased regulatory burdens or delays and changes of law

  • risks relating to inadequate insurance or inability to obtain insurance

  • risks relating to the fact that Panoro's and its partners' properties are not yet in commercial production; • risks relating to fluctuations in foreign currency exchange rates, interest rates and tax rates

  • risks relating to Panoro's ability to raise funding to continue its exploration, development, and mining activities; and

  • counterparty risk under Panoro's agreements.

This list is not exhaustive of the factors that may affect the forward-looking information and statements contained in this news release.  Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in the forward-looking information.  The forward-looking information contained in this news release is based on beliefs, expectations, and opinions as of the date of this news release.  For the reasons set forth above, readers are cautioned not to place undue reliance on forward-looking information.  Panoro does not undertake to update any forward-looking information and statements included herein, except in accordance with applicable securities laws.
