NINE MILE METALS ANNOUNCES XRF HIGH-GRADE RESULTS
UP TO 18.27% COPPER FROM THE UPCOMING DRILL AREA AT THE WEDGE PROJECT, BATHURST, NEW BRUNSWICK

TORONTO, ON. Wednesday, September 17th , 2025 – NINE MILE METALS LTD. (CSE: NINE, OTCQB: VMSXF, FSE: KQ9) (the “Company” or “Nine Mile”) is pleased to announce XRF results for volcanogenic massive sulphide (VMS) mineralization grab samples collected from the upcoming drill area on the Wedge VMS Project, in the world-famous Bathurst Mining Camp, New Brunswick, Canada (“BMC”). Discovered in 1956, Cominco operated the Wedge mine between 1962 to 1968 producing 1.5 million tonnes of predominantly copper ore. At the time of closure, (head pillar collapsed), only the upper portion of the deposit was mined. The expectation is that the lower 60% + remains untouched based upon recent drill testing and extends at depth with the 3D modeling.

As previously reported, the Cominco drill data was acquired by Nine Mile and formatted to facilitate modeling. With the addition of Mike Dufresne MSc., P.Geol., P.Geo. of APEX Geoscience Ltd. (APEX) to the Technical Advisory Committee, we provided the technical database to APEX for 3D modeling and drill hole targeting. Data provided included all historic drill holes and assays in addition to the recent successful drilling conducted by Nine Mile. To further assist in targeting, the UAV magnetics and Borehole Electro-Magnetic (BHEM) data collected by EarthEx Geophysical Solutions Inc. (EarthEX) was integrated into the modeling in addition to the initial, reprocessed MegaTEM conductivity interpretation that highlighted the Wedge and the Wedge VMS Trend.

At the Wedge Mine’s western extension, (Target 2 Figure2), modeling has focused on the unmined portions of the deposit with drill holes targeting a copper rich lens to the west and the unexplored depth extension below 150 meters where recent drilling and historical cross sections indicate mineralization occurring to a minimum depth of 300 meters. APEX is designing a sequence of drill holes to test the seven modeled TDEM conductivity plates adjacent to the Tribag VMS occurrence identified by EarthEx, (Target 3, Figure 2).

In preparation for drilling, prospecting was conducted at surface in an area proximal to the proposed drill collars along the west flank of the Wedge Mine stepping out to test the expansion westward of the Mine footprint (Figure 2). A total of 19 samples were cataloged, photographed then analyzed with a portable X-Ray Fluorescence (XRF) instrument utilizing an Olympus Vanta 50 portable 50Kv workstation and Reflex XRF software to provide instant real time geochemical information. Each sample was analyzed in 3 separate locations and the results averaged by the Reflex XRF software. The XRF process included calibrating the machine and utilizing 2 standards in the sample stream (OREAS622, CDN-BL-10) twice during analysis. The results are presented in Table 1. The samples have been forwarded to ALS Global in Moncton New Brunswick for preparation with final geochemical analysis conducted in Vancouver, British Columbia.

Highlights:

• Samples were massive VMS (Cu-Pb-Zn) mineralization collected at the upcoming Wedge drill area.
• The samples were weathered and predominantly Cu rich with minor Pb-Zn.
• Most samples consisted of 90% + sulphides and minor quartz and accessory minerals.

Samples 280370 and 280375 below (Figure 1) are examples of the massive hi grade Copper sulphide mineralization The samples were collected in the area highlighted in Figure 2, immediately to the northeast of proposed drill holes 25WG-01 and 25WD-02.

“Mike Dufresne, P.Geo., APEX’s President and an independent consultant and technical advisor commented that these high-quality conductivity targets at the Wedge Mine’s Western Extension and TriBag Target line up with the horizons that have yielded high quality VMS drill intersections at the Main Wedge Deposit and based upon the modeling to date, could provide some new exciting discoveries for Nine Mile with the planned drilling.”

Gary Lohman, P.Geo., VP Exploration, stated ”With the provincial wide fire ban lifted and APEX Geoscience’s 3D modeling complete, the team is looking forward to drilling at the Wedge Mine’s Western Extension. With the assistance of APEX, 2 main zones of mineralization have been identified, one Cu rich and another primarily Pb-Zn. Targeting has been refined by leveraging the extensive geological and geophysical data (including recent Borehole EM and plate modeling), allowing us to prioritize Cu mineralization in the upcoming program. This western extension area is the high-grade section of the deposit focused on the Copper rich Lens. These massive sulphide samples clearly demonstrate the potential of this untapped area at depth. We are building on last year’s New Eastern Extension successes with our 8 VMS drill holes with results of 136.31m of 0.68 CuEq, including 40m of 2.03% CuEq – (see News Release 03-26-2024) . A key aspect here is testing this deposit at depth and how far it extends westward resulting in additional new tonnage.

Forward-Looking Information:

This press release may include forward-looking information within the meaning of Canadian securities legislation, concerning the business of Nine Mile. Forward-looking information is based on certain key expectations and assumptions made by the management of Nine Mile. In some cases, you can identify forward-looking statements by the use of words such as “will,” “may,” “would,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue,” “likely,” “could” and variations of these terms and similar expressions, or the negative of these terms or similar expressions. Forward-looking statements in this press release include that (a) our Geophysics Program will turn its focus next to the Nine Mile Brook Project and our Eastern Portfolio, (b) both Plates A and C are large, massive, strong conductors, having both the length and depth parameters for a potentially large, mineralized body consistent with example deposits throughout the BMC, and (c) we look forward to announcing our Phase 2 Advanced Geophysics results, including full interpretations and high priority targets for our Western Portfolio. Although Nine Mile believes that the expectations and assumptions on which such forward-looking information is based are reasonable, undue reliance should not be placed on the forward-looking information because Nine Mile can give no assurance that they will prove to be correct.
