NINE MILE METALS MOBILIZES SECOND DRILL RIG TO THE TRIBAG-WEST WEDGE TARGET AREA TO TEST HIGH-PRIORITY TDEM VMS TARGETS

Nine Mile Metals Ltd.'s second drill rig has mobilized and is now on site at the Tribag-West Wedge target area of its Wedge VMS project in the Bathurst mining camp, New Brunswick. The rig will test the high-priority time-domain electromagnetic (TDEM) VMS (volcanogenic massive sulphide) targets first announced by the company on Jan. 6, 2025, with drilling expected to commence at Tribag in the coming days. Drilling at the Wedge mine continues in parallel as part of the company's 10,000-metre 2026 drill program.

Highlights:

• Second rig on site: The company's second drill rig, previously announced on June 24, 2026, has mobilized and is now on site at the Tribag-West Wedge target area, with drilling expected to commence at Tribag in the coming days.
• High-priority targets: Seven modelled TDEM conductor plates (A1, B1, C1, C2, C3, C4 and D1) associated with the Tribag (Pb-Zn) (lead-zinc) and West Wedge (Cu-Pb-Zn) (copper-lead-zinc) VMS occurrences, on the same magnetic trend as the historic Wedge mine.
• Program progress: As of Sept. 21, 2026, the company had completed 18 drill holes and 4,934.50 metres of its 10,000-metre program at the Wedge mine.
• What is next: Eight borehole electromagnetic (BHEM) surveys are commencing on perimeter holes at the Wedge mine to guide a second round of drilling on the depth and lateral extent of the Wedge lenses, while drilling gets under way at Tribag.

Moving from targets to drilling

The Tribag-West Wedge targets have been part of the company's 10,000-metre 2026 drill program since it was announced in May, with drilling planned to follow phase 3 work at the Wedge mine. The second drill rig, first announced on June 24, 2026, now allows the company to begin testing the target area, starting at Tribag, while drilling continues at the Wedge mine.

"We are pleased to finally have our second drill rig on site at the Tribag-West Wedge targets. The rig was contracted for this season, but with the demand for drill rigs right now, it took longer to arrive than we had planned. It's here now, and having a second rig means we can keep drilling at the Wedge mine while we start testing the exploration potential along the Wedge VMS trend, beginning at Tribag. These targets have been a priority since the TDEM survey was completed, and this is the kind of exploration drilling we have been waiting for. The whole team is excited to finally put a drill into them. We look forward to updates from the drill site," said Patrick J. Cruickshank, MBA, chief executive officer and director.

The Tribag-West Wedge TDEM targets

EarthEx Geophysical Solutions Inc. reprocessed legacy MegaTEM and Aerodat airborne data across the company's Western portfolio and, using late-time conductance analysis, defined 11 priority VMS trends. Priority targets 3 and 4 lie approximately 3.0 kilometres northwest of the Wedge mine and correspond directly to the West Wedge and Tribag VMS occurrences. Target 7 lies approximately six kilometres northwest of the Wedge mine along the same Wedge VMS trend, which extends for approximately 6.5 kilometres.

Maxwell plate modelling of the strong conductors defined seven individual target plates associated with the two VMS occurrences, all lying along the same magnetic trend as the historic Wedge mine.

The plates were modelled from 17.4 line kilometres of TDEM surveying completed by EarthEx over the Tribag and West Wedge areas.

All plates other than A1 sit at modelled depths of 300 to 450 metres. Plate A1 is large and at depth, suggesting a regional, stratigraphic or structural feature that has yet to be determined.

At Tribag (Target 4), mineralization has been identified at surface and in previous shallow drill holes, with a grab sample from trench LF17-11 returning 12.6 per cent Zn, 7.22 per cent Pb and 0.53 per cent Cu. At West Wedge (Target 3), historical drilling completed in the 1980s returned assays of up to 0.78 per cent Cu, 5.35 per cent Pb, 12.9 per cent Zn, 70.62 g/t Ag and 1.37 g/t Au over a 3.75-metre drill width.

"The Tribag conductors sit on the same magnetic trend as the Wedge mine, and six of the seven modelled plates sit at 300 to 450 metres. Strong conductors at depth, on trend with the Wedge, with known mineralization at surface and in the shallow historic holes. That is exactly the setup you look for in the Bathurst camp. Results from the first holes at Tribag will guide how we continue to test the target area, and we look forward to seeing what the core tells us," said Gary Lohman, BSc, PGeo, vice-president, exploration and director.

Wedge mine drilling continues

Phase 3 drilling at the Wedge mine is continuing. As reported on Sept. 24, 2026, eight BHEM surveys are commencing on perimeter holes to guide a second round of drilling on the depth and lateral extent of the Wedge lenses. Drill core is logged, photographed and sampled at the company's warehouse in Bathurst, N.B., with samples submitted to ALS Global in Moncton for analysis.
