Panoro Minerals Update on Exploration Plans at Cotabambas Project, Peru

VANCOUVER, British Columbia, July 13, 2020 (GLOBE NEWSWIRE) -- Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM) ("Panoro", the "Company"), is pleased to provide an update on the Company's exploration plans for the Cotabambas Cu/Au/Ag Project located in southern Peru.  The Cotabambas Project is Panoro's flagship project where more than 84,000 meters of exploration drilling, a NI-43-101 Resource Estimate and Preliminary Economic Assessment (PEA) have been completed. 

In 2018 and 2019, the Company completed geologic mapping and sampling, geophysical surveys and exploration drilling at a number of satellite targets in the vicinity of the two proposed open pits.  Two principal objectives are the focus of exploration work at the Cotabambas Project:

1. Addition of high grade, near-surface sulphide resources to increase the mining grade in the early part of the mine life; and the
2. Addition of near surface oxides to add a heap leach SX/EW component to the project.

The addition of high-grade sulphide mineralization and oxide mineralization to the project resource has the potential to further enhance the projects economics.

Luquman Shaheen, President & CEO, states "The proposed exploration program at the Cotabambas Project is very focused on enhancing the project economics.  An increase to the tonnage of high-grade sulphide resource and oxide resource has the potential to double the net present value of the project with little increase to the capital cost.  Recent increases in copper and gold prices have already shown the important upside to the project's net present value and internal rate of return together with a decrease in the payback period, cash cost and breakeven copper price.  The Cotabambas Project resource includes 4.2 million ounces of Gold between Indicated and Inferred categories, significantly strengthening the project economics.  We expect that continued delineation of the mineralized areas will demonstrate further upside."

The satellite targets identified for priority exploration include:

Maria Jose Targets & Petra-David Target, Cluster 1
Exploration in 2018 identified zones of primary copper mineralization hosted in andesite volcanics and porphyry in the areas of Maria Jose 1 and Maria Jose 2.  In addition, oxide copper mineralization was intersected at both the Maria Jose 2 and Petra-David target zones.  The completed exploration programs included geologic mapping and sampling, geophysical surveys and 29 drill holes for a total of 7,333 m of exploration drilling. The results were announced in press releases in 2018 and 2019.  These three zones are located within 1 km of the proposed North Pit.

Chaupec Target, Cluster 2
Exploration in 2018 and 2019 identified zones of porphyry and skarn mineralization at the Chaupec target zone in Cluster 2 located 4 kilometers to the west of the proposed North Pit.  Geologic mapping and sampling together with geophysical surveys identified high grade targets at the northern end of the Chaupec Target called Zone 1.  Five exploration drill holes for a total 997 m were completed along 1.3 kilometers of strike at Zone 1, intersecting both porphyry and skarn mineralized bodies with high copper and silver grades. The results from the exploration programs were announced in press releases in 2018 and 2019.

Guaclle Target, Cluster 1
Geologic mapping and sampling work in 2019 also identified resource potential in the area of Guaclle, located 1.5 km west and between the proposed North Pit and the Chaupec Target.  The geology includes a big package of limestone, hosting up to five stratabound bodies dipping to the east, below the Petra-David and the North Pit areas. The mineral bodies include massive chalcopyrite, bornite, pyrite and magnetite with alteration typical of skarn mineralization.

Exploration Plan
The Company is planning additional exploration work at the Chaupec Target in Cluster 1 and the Guaclle Target in Cluster 2.  The objective of the exploration programs is to identify near-surface, high-grade mineralization to provide additional early life feed to the proposed 80,000-tonne per day concentrator included in the PEA report.

The proposed exploration program at Chaupec includes:

• Geophysics 3D
• 2,000m drilling in 8 drillholes

The proposed exploration program at Guaclle includes:

• Geophysics 2D & 3D
• 2,000m drilling in 7 drillholes

The proposed geo-metallurgy study for the Copper Oxides-Mix zone at the North Pit, in preparation of the Pre-feasibility study includes:

• Data review, core logging, laboratory assaying; and a
• Preliminary geo-metallurgy model

Financing
The estimated cost for the proposed exploration programs at Chaupec, Guacclle and geo-metallurgy for the North pit is US$ 2.35 Million. The proposed exploration programs will be funded with proceeds from earlier completed funding engagements, such as:

1. Semi-annual payments pursuant to the Precious Metals Purchase Agreement with Wheaton Precious Metals;
2. Milestone payments from Hudbay Minerals pursuant to the sale of the Kusiorcco Project; and
3. Periodic payments pursuant to the sale of the Cochasayhuas Project to Mintania.

Exploration permits for the proposed programs have already been completed.  Surface rights access agreements will be required with both local communities and private land owners to initiate site activities.  The Company has had extensive success in completing such agreements over the almost nine years of progress of exploration at the Cotabambas Project.

About Panoro

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

Panoro has completed strategic partnerships at four of its projects:

1. Precious Metals Purchase Agreement with Wheaton Precious Metals at the Cotabambas Project;
2. Joint Venture with JOGMEC at the Humamantata Project;
3. Sale to Hudbay Minerals of the Kusiorcco Project for cash and NSR royalty; and
4. Sale to Mintania of the Cochasayhuas Project for cash and NSR royalty.

These partnerships would provide, if all received, US$ 15.5 million of funding to Panoro from 2020 to 2024, not including the potential NSR royalties from the Kusiorcco and Cochasayhuas Projects.

At the Cotabambas Project, the Company is focused on delineating the growth potential while optimizing the project economics.  Exploration and step-out drilling from 2017, 2018 and 2019 has identified the potential for both oxide and sulphide resource growth.

Summary of Cotabambas and Antilla Project Resources

Preliminary Economic Assessments (PEA) have been completed for both the Cotabambas and Antilla Projects, the key results are summarized below.

Summary of Cotabambas and Antilla Project PEA Results

The 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 updated PEA will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
