Panoro Minerals Delineating New Porphyry Discovery at Humamantata Project, Peru
VANCOUVER, British Columbia, Oct. 27, 2020 (GLOBE NEWSWIRE) -- Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM) (“Panoro” or the “Company”) is pleased to provide an
update on the progress and results from exploration activities at the Humamantata Project in Southern Peru.
The Company has identified a new copper porphyry with anomalous grades of copper, gold and silver at the Humamantata Project. The porphyry mineralization is outcropped in a number of zones over an area of approximately 1800 m by 700 m. In addition, eighteen hydrothermal breccias have been identified over the length of the project with anomalous grades of silver.
Four Target areas over the Humamantata Project were identified in earlier mapping and sampling programs. The porphyry mineralization is contained within Target 1, where the Company has mapped and sampled three sub areas, T1-1, T1-2 and T1-3, of new Cu, Au and Ag porphyry outcroppings with potassic alteration over an area of 600 m by 300 m. The highest copper grades of up to 2.7% Cu have been mapped with abundant and different generations of early (A-type) quartz veinlets including magnetite, chalcopyrite and bornite, with secondary feldspar and biotite alterations. Additionally, a breccia texture filled with bornite and chalcopyrite was also recognized. The table below summarizes the average assays results for the three porphyry outcroppings.
The porphyries are made up of tonalite and monzonite composition, with the copper mineralization extending up to 100 m inside the diorite host rock and to the phyllic alteration, with the progressive appearance of the propylitic alteration. In the diorite domain the copper sulfides overprint an extended secondary biotite dissemination and fill sheeting quartz veinlets with K feldspar in early halo.
Targets 2 and 4 cover an area of 3 km x 3 km and are located to the south of Target 1. They include a group of ten hydrothermal breccias crosscutting the sedimentary sequences of the Velille and Hualhuany sandstones and the Ferrobamba limestones suggesting the high vertical continuity crosscutting over all the cretassic sequence in the area. The breccias have long structural control containing high silver anomalies with grades measured as high as 332 g/t Ag. The Breccias are exposed at surface with dimensions ranging from 150 m by 15 m to 750 m by 300 m.
A possible connection with a blind Cu-Au, Ag porphyry at depth and laterally is being evaluated. There are 8 other groups of hydrothermal breccias extending the mineral continuity an additional 4 km to the south of Target 3.
Luquman Shaheen, President & CEO, states, “We are encouraged by the results of the exploration work to date at the Humamantata Project. The identification of a new porphyry looks promising as the surface grades, potential size and style of mineralization all point towards a target worthy of further exploration including drilling to test potential vertical extension and grade distribution. The breccia pipes located throughout the property are indicative of the potential to further delineate porphyry mineralization in the areas adjacent to and at depth to the breccias. We look forward to planning the drilling program with our partner JOGMEC as soon as the review and analyses of the exploration results is complete.”
During September, a 24.3 km Induced Polarization survey was completed over Targets 1 and 4, complementing the 29.1 km completed over Target 2 from February to March 2020 and the 80.4 km Magnetometry survey completed in 2019 over all the targets. The analysis of the new porphyry zone and breccias is underway with the results to come from the mineralogical characterization, geochemistry and geophysics studies. The next stage of the exploration program will be finalized in conjunction with Panoro’s partner, JOGMEC, after this analysis is completed during November and December.
The process to obtain the permits for the proposed exploration drilling program is being advanced in parallel with above outlined exploration works.
The exploration work at the Humamantata Project is fully financed by JOGMEC pursuant to the joint venture agreement, whereby JOGMEC has an option to earn up to 60% indirect beneficial interest after the investment of US$8.0 Million.
Panoro is a uniquely positioned Peru focused copper exploration and development company. The Company is advancing its flagship project, Cotabambas Copper-Gold-Silver Project and its Antilla Copper-Molybdenum Projects located in the strategically important area of southern Peru.
Panoro has completed strategic partnerships at four of its projects:
- Precious Metals Purchase Agreement with Wheaton Precious Metals at the Cotabambas Project;
- Joint Venture with JOGMEC at the Humamantata Project;
- Sale to Hudbay Minerals of the Kusiorcco Project for cash and NSR royalty; and
- Sale to Mintania of the Cochasayhuas Project for cash and NSR royalty.
These partnerships would provide, if all received, US$ 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.
Summary of Cotabambas and Antilla Project Resources
|Cu (%)||Au (g/t)||Ag (g/t)||Mo (%)||
|@ 0.20% CuEq cutoff, effective October 2013, Tetratech|
|@ 0.175% CuEq cutoff, effective May 2016, Tetratech|
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
|Key Project Parameters||
|Process Feed, life of mine||million tonnes||483.1||118.7|
|Process Feed, daily||Tonnes||80,000||20,000|
|Strip Ratio, life of mine||1.25 : 1||1.38 : 1|
Annual Average Payable Metals
|Initial Capital Cost||million USD||1,530||250|
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.
