Panoro Minerals Update on Exploration at Humamantata Project, Peru
VANCOUVER, British Columbia, Aug. 26, 2020 (GLOBE NEWSWIRE) -- Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM) (“Panoro”, the “Company”), is pleased to provide an update on the progress and results from exploration activities in 2020 at the Humamantata Project in southern Peru.
Work at the Humamantata Project was suspended in March 2020 in accordance with Peruvian regulations pertaining to the Covid-19 pandemic. The Stage 2 reactivation of economic activities in Peru includes permission for exploration activities to recommence with approved Covid-19 protocols. Panoro’s protocols have been submitted to and approved by the Peruvian Ministry of Health. Panoro’s health and safety and community relations team has mobilized to site and the geology team will be arriving this week.
With the work in progress (see previous press release), three Targets have been identified over the Humamantata Project:
- Target 1 includes an Intrusive and a Skarn with oxides, secondary and primary copper sulfides in the contact between a porphyry and the Ferrobamba limestones.
- Target 2 includes hydrothermal breccias with Ag, Au and Cu, Mo anomalies, hosted in the contact between a porphyry environment and limestones/sandstones packages.
- Target 3 includes hydrothermal breccias and quartz stockwork with high Ag and low Au anomalies, hosted in sandstone layers in an epithermal environment.
In 2020 the main fieldwork was concentrated in Target 2, where the mapping identified a complex lithologic setting requiring further 1:1000-scale mapping and oriented rock chip sampling by mineral structure to complement the Induced Polarization and Magnetics surveys to determine and review a possible connection with Target 1.
In Target 2, we have identified a hydrothermal breccia (the “BX-7”) - 750m in length by 60 to 300m in width, striking in a N45E direction along the north contact of a porphyry of Tonalite composition located at the southeast side. To the west side is an outcrop of a second hydrothermal breccia (the “BX-6”) in the contact between the limestone and sandstone packages (see linked geologic map).
In the Target 2 area there is a mineral outcropping continuity along the 1.2 km length, from the intrusive to the BX-6, passing through the BX-7. There is a metal zoning from a porphyry environment with Cu, Mo, Au in the intrusive domain to an epithermal environment in the BX-6 with high anomalies of Ag, Pb, Zn; passing through a mesothermal environment with high Ag and minor Au values in the BX-7.
The BX-7 shows silver grades from 0.5 to 7.5 ounces/tonne with anomalies of gold, in spite of the pervasive supergene oxidation and argillization. The mineralization is conformed by pyrite, pyrrhotite, magnetite, chalcopyrite, galena acantite-argentiferous, hematite, goethite and jarosite, all in replacement and dissemination textures into the breccia matrix. This information is supported with mineralogy, petrography and spectrometry studies. The chargeability and magnetics geophysics signatures suggest certain continuity of the BX-7 at depth, below the intrusive contacts. This breccia is emerging as one of the best targets for the drilling campaign.
Exploration with mapping and rock sampling will continue during the next 3 months to define specific areas for drilling in Targets 1 and 2.
The completion of the process to obtain the FTA, environmental permit for proposed exploration drilling program has advanced, receiving the authorization of all private land owners around the project. In addition, the FTA will be completed and approved in a few weeks after the workshop with public authorities is completed.
The Permit to Start Drilling Operations is expected to be approved in time to commence the proposed exploration drilling program during the last quarter of 2020. The next stage of the exploration program will be finalized in conjunction with Panoro’s partner, JOGMEC, after the completion of mapping, geochemistry and geophysical surveys.
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:
- Precious Metals Purchase Agreement with Wheaton Precious Metals at the Cotabambas Project;
- Joint Venture with JOGMEC at the Humamantata Project;
- Sale to Hudbay Minerals of the Kusiorcco Project for cash and NSR royalty; and
- 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.

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.
