Research News and Market Data on PNPNF
TORONTO, July 15, 2026 – Power Metallic Mines Inc. (the “Company” or “Power Metallic”) (TSXV: PNPN) (OTCBB: PNPNF) (Frankfurt: IVV1) is pleased to provide final assay results from its Winter 2026 drill program and the voting results from its Annual General and Special Meeting (“AGSM“) held on June 30, 2026, in Toronto, Ontario.
Summary
These assays from Power Metallic’s winter 2026 drill program complete the drill results to be used for the initial NI-43-101 Mineral Resource Estimate (MRE) on Lion. Completion and reporting of the MRE estimates on Lion and the Nisk deposit is scheduled for the end of July. This MRE will form the basis for a Preliminary Economic Assessment (PEA) to begin immediately following the completion of the MRE.
Lion Zone MRE In-fill program
This news release includes drill holes defining the eastern side of the Lion Zone close to surface (Figure 1). All holes are in preparation for the 2026 Mineral Resource Estimate (MRE). The infill drill holes in this release were drilled to delimit the eastern side of Lion to increase the confidence of modelling the zone, particularly within the range of a potential future open pit.
In-fill drill holes in the shallow central parts of the deposit continue to report good near surface grades as evidenced by PML-26-116 which intersected high-grade copper near surface with 36.42 m @ 2.83% CuEqRec1 at 75m below surface, including semi-massive mineralization with 6.00 m @ 12.38% CuEqRec1. (Table 1 and Figure 1).
Drill holes included in Figure 1 but not in the table of Lion results (Table 1) occur on the eastern side of Lion, delimiting the eastern edge for MRE resource modelling. These holes did intersect the favourable mineralized structure, but had low grade assays, including individual assays of up to 0.49 g/t Pt and 0.62 g/t Pd, as well as anomalous Cu and Au, defining the mineralized structure’s location. Two holes also tested near surface between Lion and Tiger, again intersecting the mineralized structure with weak Cu, Pd results.

Annual General and Special Meeting Results
Power Metallic’s held its AGSM on June 30, 2026, in Toronto, Ontario.
Shareholders voted in favor of all items of business presented at the AGSM, as outlined in the proxy-related materials, including the Notice of Meeting and the Information Circular dated May 15, 2026 (the “Information Circular“). These items included the election of directors such that each of Terry Lynch, Peter Kent, Les Mallard, Greg McKenzie, Steve Beresford, and Seamus O’Regan were elected as directors, the appointment of the Company’s auditor, MNP LLP, the re- approval of the Omnibus Equity Incentive Plan, and the approval of an amendment to the Company’s Articles to increase the quorum threshold for shareholder meetings. Just over 33.42% of the Company’s issued and outstanding common shares as of the record date of the AGSM were voted. For more information on the resolutions and the Omnibus Equity Incentive Plan, shareholders are encouraged to refer to the Information Circular available at the Company’s profile on SEDAR+.
The shareholder approval of the Articles’ amendment to increase the quorum threshold for shareholder meetings to 33-1/3%, will allow the Company’s Articles to meet the quorum threshold expected for companies listed on a U.S. national stock exchange. With shareholder approval in hand, and as disclosed in the Information Circular, the Company intends to implement the Articles amendment at such time as the Board of Directors has determined to proceed with seeking a listing on a U.S. national stock exchange.
The full scrutineer’s report for the AGM votes will be posted on the company’s website by the end of the week at the following address: https://www.powermetallic.com/financial_statements/.
“We are grateful for the strong support of our shareholders at this year’s Annual General and Special Meeting. Receiving approval for the amendment to our Articles to align our quorum threshold with U.S. national exchange requirements is a meaningful step forward in our mission to bring Power Metallic’s story to a broader investor audience. With the Lion Zone delivering some of the highest-grade polymetallic intercepts in the world, exceptional metallurgical recoveries, and a pipeline of catalysts ahead — including our upcoming mineral resource estimate — we believe a U.S. national exchange listing will unlock a significant re-rating opportunity and introduce this company to a broader community of institutional and retail investors.” — Terry Lynch, CEO, Power Metallic Mines Inc

About Power Metallic Mines Inc.
Power Metallic is a Canadian exploration company focused on advancing the Nisk Project Area (Nisk–Lion–Tiger)—a high–grade Copper–PGE, Nickel, gold and silver system—toward Canada’s next polymetallic mine.
On 1 February 2021, Power Metallic (then Chilean Metals) secured an option to earn up to 80% of the Nisk project from Critical Elements Lithium Corp. (TSX–V: CRE). Following the June 2025 purchase of 313 adjoining claims (~167 km²) from Li–FT Power, the Company now controls ~330 km² and roughly 50 km of prospective basin margins.
Power Metallic is expanding mineralization at the Nisk and Lion discovery zones, evaluating the Tiger target, and exploring the enlarged land package through successive drill programs.
Beyond the Nisk Project Area, Power Metallic indirectly has an interest in significant land packages in British Columbia and Chile, by its 50% share ownership position in Chilean Metals Inc., which were spun out from Power Metallic via a plan of arrangement on February 3, 2025.
It also owns 100% of Power Metallic Arabia which owns 100% interest in the Jabul Baudan exploration license in The Kingdon of Saudi Arabia’s Jabal Said Belt. The property encompasses over 200 square kilometres in an area recognized for its high prospectivity for copper gold and zinc mineralization. The region is known for its massive volcanic sulfide (VMS) deposits, including the world-class Jabal Sayid mine and the promising Umm and Damad deposit.

QAQC and Sampling
GeoVector Management Inc (“GeoVector”) is the Consulting company retained to perform the actual drilling program, which includes core logging and sampling of the drill core.
All core in this news release is either HQ or NQ sized core. Drill core is re-fitted and measured. Geotech on core includes photographs (wet & dry), rock quality index, magnetic susceptibility, conductivity, and recovery estimates. Core is logged for lithology, mineralogy, and structural features, and sample intervals are delineated and tagged.
Sampled core is mechanically sawn, and half-core is retained for future reference. GeoVector’s QAQC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results. QAQC and data validation was performed, and no material errors were observed.
All samples were submitted to and analyzed at Activation Laboratories Ltd (“Actlabs”), a commercial laboratory independent of Power Metallic with no interest in the Project. Actlabs is an ISO 9001 and 17025 certified and accredited laboratories. Samples submitted through Actlabs are run through standard preparation methods and analysed using RX-1 (Dry, crush (< 7 kg) up to 80% passing 2 mm, riffle split (250 g) and pulverize (mild steel) to 95% passing 105 μm) preparation methods, and using 1F2 (ICP-OES) and 1C-OES – 4-Acid near total digestion + Gold-Platinum-Palladium analysis and 8-Peroxide ICP-OES, for regular and over detection limit analysis. Pegmatite samples are analyzed using UT7 – Li up to 5%, Rb up to 2% method. Actlabs also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
