VANCOUVER, B.C., June 2, 2021 – Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM, OTCQB: POROF) (“Panoro or the “Company”) would like to provide an update on exploration activities at the Humamantata project.  The Humamantata Project is being advanced under the terms of a Joint Venture agreement the Japan Oil, Gas and Metals National Corporation (JOGMEC)

The Company has completed an extensive exploration program including geologic mapping, geochemical sampling and analysis and ground a geophysics program in preparation for a phased exploration drilling program to follow.  The work to date has identified four targets:

  • Target 1, Cu/Au/Ag porphyry mineralization located to the north of the property;
  • Target 2, Ag Hydrothermal Breccia Mineralization located to the south of Target 1;
  • Target 3, Ag Hydrothermal Breccia and Ag-Cu Stockwork Mineralization in the south property; and
  • Target 4. Ag Hydrothermal Breccia and Cu-Au Skarn Mineralization located to the north of Target 2.

Luquman Shaheen, President and CEO, states, “We are pleased that the ongoing work at the Humamantata Project continues to identify strong targets for the proposed exploration program funded by our partner, JOGMEC.  The close proximity of other significant copper mines such as Constancia and Las Bambas is a good indicator of the potential for this project.  Through the very difficult period of Covid-19 related restrictions, our team has progressed on both the geologic and permitting fronts.  We are hopeful that the proposed drilling program will continue to validate the growing potential estimated for the Humamantata Project.”

Targets 1, 2 and 4 have been the focus of exploration and analyses over the last 3 months to define the proposed exploration drilling program. Exploration work at Target 4 has identified important exploration potential in a Cu-Au Skarn type mineralization, in addition to the previously identified Targets 1 and 2. The Company has completed including 3G works (mapping, geochemistry, geophysics), data analysis/interpretation and a preliminary drilling program in Targets 1, 2& 4.

To date the Company has completed the following field activities:

  • Geologic mapping at 1:1,000 scale over an area covering 1,200 hectares of the total 3,600 hectares of concessions comprising the Humamantata Project;
  • 647 samples from surface outcrops have been collected over the target areas for geochemical analysis;
  • 68 fresh and mineralized rock samples for Mineragraphy and Petrography studies;
  • 130 fresh and mineralized rock samples for a Lithogeochemistry study;
  • 496 rock samples by PIMA Spectrometry for a mineral alterations study;
  • 53.2 km of ground Induced Polarization geophysical surveys; and
  • 80 km of ground Magnetic Resonance surveys.

The attached map shows the results of the geologic mapping and geochemical analyses identifying the Targets 1, 2 and 4, see Insert 1.

At Targets 2 and 4 the bottom of the creek indicates the main overthrust faulting in an almost north-south direction, pushing from west to east. The Hualhuani sandstone and Ferrobamba limestones are ovethrusted above the Velille sandstones. At the front of this faulting occur the hydrothermal breccias #7, #8, #9 and two dikes of porphyry andesite composition with potassic alteration confirmed by the petrographic studies. The main concentration of silver values located in these breccias are accompanied with traces of pyrrotite, chalcopyrite and native gold, defined by the mineragraphic studies, and surrounded by evidence of Chlorite-Fe, Alunite-K and illite-Fe as indicated with the Spectrometry study with PIMA in the Target 1. The Skarn type mineralization occurs aligned along this structural control. Complementing the structural model, the hydrothermal breccias #4, #5, #6, #7 follow a secondary overthrust faulting pushing from north to south direction, and the breccia #18 a gravitation fault dipping the blocks to the east.

The interpretation of the exploration work to date is illustrated in the attached section of the property from north to south.  Insert 2 illustrates high magnetic anomalies located to both sides of the Velille sandstone in contact with the igneous intrusives as well the highest electric conductivities developed in the upper levels of the sandstones package, below the outcroppings of the BX 7, 9 and the quartz stock to the north. The porphyry stock environment is interpreted at depth, next to the contacts with the igneous rocks and below the hydrothermal breccias.

The 3-D geophysical interpretation is identifying a potential connection between the Hydrothermal Breccias #5, #6, #7, #8, #9 and #18 of the Target 2, all of which are dipping towards Target 4 where a Cu-Au skarn mineralization outcrops at surface. In this area the sandstones hosting the breccias with high silver contents show a wide dissemination of phyllic alteration with pyrite-quartz veinlets-sericite, as one of the main features explaining the high chargeability anomaly occurring below both targets. The Skarn evidence occurs over local expositions with andradite garnet, chalcopyrite and bornite mineralization showing grades from 0.49 to 1.9 %Cu and 0.13 to 0.31 Au g/t (see previous press release of November 30, 2020), surrounded by a corridor containing values above 100pm Cu hosted in sandstones. This copper anomaly is matching with a generation of quartz veinlets including hematite and jarosite overprinting the phyllic alteration and overall striking in North-West direction.

The geology/geochemistry/geophysics interpretation in 3D also indicates notable low magnetics in the North-South direction connecting Targets 2 and 4, where high chargeability anomalies, hydrothermal breccias and skarn evidence are incorporated in a single structural control, see see Insert 3.

The drilling program in Target 1 has been defined, while at Targets 2 and 4 additional exploration and interpretation work is being completed to finalize drilling plans.

The permitting completed to date at the project includes:

  • Environmental Technical File (FTA) Approval;
  • Water Permit Approval;
  • Archaeology Permit Approval; and
  • Surface Access Approval (Partial).

The Company anticipates the completion of the final surface access agreements and the approval of the Start of Operations Permit in time to commence mobilization of drilling equipment in June.

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.

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.
