PML Panoro Minerals Ltd

VANCOUVER, BC, July 17, 2023 /CNW/ - Panoro Minerals Ltd. (TSXV: PML) (Lima: PML) (Frankfurt: PZM) (OTCQB: POROF) ("Panoro", the "Company") is pleased to announce results of nine additional drillholes that will provide additional information for the new mineral resource estimation at the Cotabambas Cu/Au/Ag Project in southern Peru.

The drillhole intersection highlight are as follows:

• Drillhole CB-224 intersected 371m of the porphyry stock hosting 316.9m of copper and gold mineralization averaging 0.72% Cu, 0.50g/t Au and 4.01g/t Ag (1.16% Cueq.). The intersection includes a supergene profile of copper oxides and sulfides enrichment intersected 3m from surface and underlain by 168.1m of primary sulfides grading 1.0% Cu, 0.73g/t Au, 5.91g/t Ag (1.64% Cueq), including 94.7m averaging 1.27% Cu, 1.04g/t Au, 7.15g/t Ag (2.17% Cueq).
  
  
• Drillhole CB-212a intersect 200m of the porphyry stock in contact with the diorite host rock, hosting 198.6m of copper and gold mineralization grading 0.83% Cu, 0.74g/t Au, 3.80g/t Ag (1.46%Cu eq). The intersection includes a supergene profile with copper oxides and mix zone intersected from surface and underlain by 163.5m of primary copper sulfide averaging 0.76% Cu, 0.82g/t Au, 4.06g/t Ag (1.46%Cu eq), including 64.0m of primary copper sulfide grading 1.10% Cu, 1.32g/t Au, 4.94g/t Ag (2.21% Cueq).

Luquman Shaheen, President & CEO commented, "This group of nine drillholes completes the 2022-2023 campaign of infill and step out drilling in both North and South Pits, for a total of approximately 13,000m of drilling. The results indicate the potential for an increase in the high-grade component of the Cotabambas Projects resource and an important increase in the total project resource. The high-grade zone has been better delineated indicating that it is structurally controlled in North-Northeast direction, where the high grade zone remains open both along strike, to the northeast of the North Pit, and to the southwest of the South Pit. The high-grade zone is also open at depth. The drilling has also indicated better continuity of the high-grade zone where the potential for additional near surface high-grade resource can increase the mining grade in the early part of the mine life. Our team will now turn its focus to, together with the independent consultants and Qualified Persons, updating the resource estimate and completing the NI 43-101 technical report which is targeted for completion in September. In addition to the update of the resource estimate, our team has been completing trade-off studies aimed to improve the metallurgical recoveries, reduce operating and capital costs and reduce the footprint of the project. Results from these studies are identifying important opportunities to further strengthen the Cotabamabas Projects economics."

Drillholes CB-210, 212a, 217, 218, 219, 220, 221, 222 and 224 were drilled targeting an upgrade of the exiting inferred resource to indicated category and expand the high-grade component of the mineral resource at the North Pit. The high-grade continuity remains open at depth and along strike to the northeast. See the drillhole locations on Figure 1. The principal mineralization intersections are listed in the table below.

Drillhole CB-210 is an exploratory step out drillhole executed to review the southwest continuity of the mineralization in the North Pit. This hole intersected a copper anomaly of 38.0 m length grading 0.12% Cu, 0.04g/t Au and 0.98g/t Ag (0.16% Cueq) into the diorite host rock. This hole confirms, as indicated from other drill holes in the area, that faulting in the Northwest to East-West direction has displaced the mineralization vertically in this area of the North Pit as well as farther to the southwest towards the South Pit. (Figure 2).

Drillhole CB-212 is an infill drillhole indicating the continuity from surface to approximately 350 m depth of the high-grade zone in the north side of the North Pit. The hole intersected 198.6m of copper mineralization averaging 0.83% Cu, 0.74g/t Au, and 3.80 g/t Ag (1.46% Cueq) including a supergene profile with copper oxides and mixed zone, overlaying 163.5m of primary copper sulfide averaging 0.76% Cu, 0.82g/t Au, 4.06g/t Ag (1.46% Cueq), including 64.0m of primary copper sulfide mineralization averaging 1.10% Cu, 1.32g/t Au, 4.94g/t Ag (2.21% Cueq). The mineralization is contained within approximately 200m of the porphyry stock intruding the diorite intrusive host rock with extended potassic alteration with secondary biotite, orthoclase, magnetite veinlets surrounded by SCC type alteration (Figure 3).

Drillhole CB-217 is an infill drillhole targeting mineralization intersected previously in drillholes CB-55 and CB-213. The drillhole intersected from near surface, 408.9m of hypogene mineralization averaging 0.32% Cu, 0.15g/t Au, 1.60g/t Ag (0.46%Cueq) intruded by a porphyry dike of 50m width expanding into the diorite host rock. The intersection includes 34m of mixed copper mineralization near the surface grading 0.86% Cu, 0.10g/t Au, 1.19g/t Ag (0.95% Cueq), and three intervals of hypogene copper mineralization of 111.6m grading 0.29% Cu, 0.10g/t Au, 0.82g/t Ag (0.38% Cueq), 71.3m averaging 0.38% Cu, 0.36g/t Au, 2.05g/t Ag (0.69%Cueq), and 74.6m grading 0.28% Cu, 0.12g/t Au, 2.84g/t Ag (0.40% Cueq). The potassic, SCC and minor phyllic alterations are the typical for hydrothermal alterations (Figure 4).

Drillhole CB-218 is an infill hole targeting the constraint of the high-grade zone generated by drillhole CB-128 previously executed and intersecting high grade mineralization 100m below CB-218. The drillhole intersected 343.0m of hypogene copper mineralization grading 0.18% Cu, 0.07g/t Au, 0.94g/t Ag (0.25% Cueq), including 90.0m averaging 0.34% Cueq. The mineralization is related to a group of five porphyry dikes intruding the diorite host rock. The intersections of CB-218 represent the upper zone of a porphyry stock cupula of almost 600m width that hosts several intervals of copper and gold high grades with potassic and SCC alterations (Figure 5).

Drillhole CB-219 is an infill hole located in the north extreme of the North Pit targeting the copper mineralization supergene profile, intersected previously by drillholes CB-27 and CB-134. This hole intersected 30.1m averaging 0.16%Cu, 0.05g/t Au, 4.75g/t Ag (0.24% Cueq) (Figure 6).

Drillhole CB-220 was located near the west side of the North Pit, intersecting two intervals of copper oxide mineralization with 33.4m in length averaging 0.50% Cu, 0.12g/t Au, 1.52g/t Ag (0.61% Cueq) and 12.8m grading 0.22% Cu, 0.24g/t Au and 5.54g/t Ag (0.46% Cueq). The bottom of the hole intersected two intervals of hypogene copper sulfides of 26.0m and 46.0m lengths averaging grades of 0.30% Cueq and 0.26% Cueq, respectively. This hole limits the margin of the mineralization in this sector of the North Pit (Figure 7).

Drillhole CB-221 this hole is a step out located in the north side of the North Pit, intersecting 125.8m of copper mineralization averaging 0.39% Cu, 0.08g/t Au, 1.34g/t Ag (0.47% Cueq). This intersection includes 34.3m of copper oxide mineralization grading 0.67% Cu, 0.09g/t Au, 1.73g/t Ag (0.76% Cueq) underlain by 91.5m of hypogene copper mineralization averaging 0.29% Cu, 0.07g/t Au and 1.20g/t Ag (0.36% Cueq), including 12.10m averaging 0.89% Cueq. This hole is aligned in the same cross section with the drillholes CB-222 and CB-219, into an area where the porphyry stock is displaced between 200m to 400m to the northeast by an almost east-west striking fault. Nevertheless, this hole intersected copper mineralization across this structural control and near the surface (Figure 6).

Drillhole CB-222 this is a step out drillhole located 100m to the northwest of the CB-221. CB-222 intersected 95.7m of copper oxide mineralization averaging 0.19% Cu, 0.04g/t Au, 0.82g/t Ag (0.23% Cueq) underlain by 47.3m of hypogene copper mineralization averaging 0.15% Cueq (Figure 6).

Drillhole CB-224 is an infill drillhole targeted to upgrade inferred to indicated resources 100m to the southeast of the previously completed drillhole CB-212. CB-224 intersected 316.9m of copper and gold mineralization averaging 0.72% Cu, 0.50g/t Au and 4.01g/t Ag (1.16% Cueq.). This includes a supergene profile of 13.7m of copper oxides plus 13.1m of enriched sulfides averaging 1.31% Cueq and 1.56%Cueq, respectively. Underlying the supergene zone is 168.1m of primary sulfides grading 1.00% Cu, 0.73g/t Au, 5.91g/t Ag (1.64% Cueq), including 94.7m averaging 1.27% Cu, 1.04g/t Au, 7.15g/t Ag (2.17% Cueq), and a second interval of 91.8m grading 0.34% Cu, 0.27g/t Au, 2.23g/t Ag (0.58% Cueq) including 25.9m averaging 0.71% Cu, 0.70 g/t Au, 4.36g/t Ag (1.31% Cueq).The mineralization intersected in CB-224 is hosted within a 371m wide porphyry stock where the high grade zone is structurally controlled to the east and follows a high grade corridor of approximately 800m along strike and is open at depth and along strike in northeast direction (see Figure 8) 

Panoro has commenced an update on the mineral resource estimate, contracting AGP Mining Consultants Inc., an independent engineering firm based on Toronto, Canada. The study is led by the Paul Daigle, P.Geo. (Principal Resources Geologist) and Gordon Zurowski (Mining Lead/Mine Costing) who will complete the NI 43-101 technical report. Work on the study commenced the first week of July 2023 and results are expected in approximately 2 months. The report will include the potential generated in the Maria Jose, Petra-David and Chaupec Skarn exploration targets identified during the 2017-2018 drilling campaign and also the potential in the Guaclle skarn target during the 2022-2023 drilling Campaign.

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.

Summary of Cotabambas Project Resources ¹

A PEA has been completed for the Cotabambas Project; the key results are summarized below:

Summary of Cotabambas Project PEA Results 

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.
