VANCOUVER, B.C., April 19, 2022 – Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM, OTCQB: POROF) is pleased to announce the mobilization of a drilling contractor to commence the pre-feasibility study infill and step out drilling program at the Cotabambas Project. The proposed drilling program will commence within the next two weeks and is scheduled to be completed in December 2022. Additional drilling is planned for 2023 to test satellite targets identified within Cluster 1 and Cluster 2 of the Cotabambas Project.

The infill drilling program goal is to upgrade 100% of inferred category resource included in the Preliminary Economic assessment ("PEA") mine plan to indicated category. The infill drilling will include an estimated 44 drillholes for a total estimated 12,192 meters at the proposed North and South Pits. The current mineral resources included in the mine plan of the PEA includes 127.3 million tonnes at Indicated category and 355.8 million tonnes at Inferred category.

Step-out drilling of approximately 4,778 meters will target the growth of both the copper oxide and high grade sulphide resource for inclusion into the mine plan for the pre-feasibility study. The program will be distributed between 22 drill holes located in close proximity to the North and South Pits as well as over the exploration targets of Maria Jose 1, Maria Jose 2, Petra and David, previously drilled in 2017 and 2018.

Both the infill and step out drilling programs are constrained within Cluster 1 where various targets of copper and gold mineralization are characterized by quartz monzonite porphyry centers intruding diorite and volcanic host rocks. The proposed exploration work is within the already approved exploration area of the Cotabambas Project. The permits allow for drilling from up to 500 drilling platforms.

In addition to the pre-feasibility drilling program Panoro is scoping the engineering, environmental and social studies to support the pre-feasibility work program. Metallurgical, tailings trade off, heap leach pad and SX/EW plant location and open pit geotechnical studies will be completed in 2022 in support of the pre-feasibility study planned for completion in 2023.

Permits for the proposed exploration program are in place and access preparations are underway.

Having completed the funding for the pre-feasibility studies at the end of 2021 and first quarter of 2022 we look forward to advancing the pre-feasibility works and demonstrating the economic upside to the Cotabambas Project. Our targeted resource growth, improved recoveries, addition of a cathode production circuit and significantly higher commodity prices will together enhance the already significant value of the Cotabambas Project.”, states Luquman Shaheen, President & CEO.

About Panoro

Panoro is a uniquely positioned Peru-focused copper development company. The Company is advancing its flagship Cotabambas Copper-Gold-Silver Project located in the strategically important area of southern Peru.

The Company’s objective is to complete a Prefeasibility study in 2023 with work programs commencing in Q1 2022.

At the Cotabambas Project, the Company will first focus on delineating resource growth potential and optimizing metallurgical recoveries. These objectives are expected to further enhance the project economics as part of the Prefeasibility studies during 2022 and 2023. Exploration and step-out drilling from 2017, 2018 and 2019 have already identified the potential for both oxide and sulphide resource growth.

PEAs are considered preliminary in nature and include Inferred Mineral Resources that are considered too speculative to have the economic considerations applied that would enable classification as Mineral Reserves. There is no certainty that the conclusions within the PEAs will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

Examples of forward-looking information and statements contained in this news release include information and statements with respect to:

  • Panoro delineating growth potential at the Cotabambas Project, while optimizing project economics;
  • mineral resource estimates and assumptions; and
  • the PEAs, including, but not limited to, base case parameters and assumptions, forecasts of net present value, internal rate of return and payback.

Various assumptions or factors are typically applied in drawing conclusions or making the forecasts or projections set out in forward-looking information.
