  58.9 m at 1.09% Li₂O.
  • CS25-039: 12 separate intervals, including:
    • 108.5 m at 1.62% Li₂O,
    • 71.0 m at 1.84% Li₂O,
    • 77.7 m at 1.48% Li₂O, and
    • 107.4 m at 1.87% Li₂O

• Three (3) drill rigs continue to operate on the Cisco Project, with a fourth scheduled to start at the end of October 2025.

• The upcoming drilling programs will be primarily focused on infill-scale drilling within the main mineralized zone, supporting the Company’s efforts to deliver an initial inferred Mineral Resource Estimate in the first half of 2026.

Q2 Metals Corp. (TSX-V: QTWO) (OTCQB: QUEXF) (FSE: 458) is pleased to report assay results from the ongoing 2025 drill program at the Company’s Cisco Lithium Project, located within the greater Nemaska traditional territory of the Eeyou Istchee James Bay region of Quebec, Canada.

“Hole 36, with its 272.5 metres of continuous spodumene pegmatite grading 1.61% Li₂O is a significant confirmation of the substantial width of the Mineralized Zone, especially when considered alongside intervals such as the 347 metres of continuous spodumene pegmatite in Hole 21,” said Neil McCallum, Vice President of Exploration for Q2 Metals. “Importantly, the Mineralized Zone remains open at depth and along strike, indicating strong potential for further expansion. Our geology team has designed a robust drilling program for the upcoming drilling program as we continue to define the extent of the Mineralized Zone and advance toward an inferred Mineral Resource estimate.”

The analytical results reported herein represent the first three (3) drill holes completed during the summer 2025 drill campaign.

As previously reported (see news release of June 10, 2025), hole CS25-036 was paused prior to the start of this year’s goose-hunting season break and ended before the intended completion depth. Several wide pegmatite intervals were intercepted, and assays were reported on the first 302 metres (“m”) of drilling completed during the winter 2025 drill campaign. The entirety of the assays on drill hole CS25-036 are now reported herein. The analytical results continue to confirm the robust width of the mineralized zone at this location.

Drill holes CS25-038 and 039 confirmed the mineralization at the southern portion of the mineralized zone with many intervals reporting greater than 1.5% Li2O. Drilling at the Cisco Project is ongoing, with three (3) drill rigs currently operating on site. A fourth drill rig has been mobilized to site and is scheduled to start at the end of October 2025, further accelerating the pace of the exploration program.

The primary focus of the fall and winter drilling campaign with be on infill-scale drilling within the main mineralized zone. The work is designed to support the Company’s objective of delivering an initial inferred Mineral Resource Estimate in the first half of 2026.

Pegmatite intervals and analytical results from the current program will be reported as they are received and reviewed.

All intervals of greater than 2 m of core-length and greater than 0.30% Li2O are included in Table 1. Internal dilution of non-pegmatite material was limited to intervals of less than 5 m. No specific grade cap or lower cut-offs were used during grade and width calculations. All intervals are reported as core widths and mineralized intervals in all the holes drilled thus far are not representative of the true width as the modelled pegmatite zones are being refined with every additional hole.

Sampling, Analytical Methods and QA/QC Protocols

All drilling was conducted using diamond drill rig with NQ sized core and all drill core samples are shipped to SGS Canada’s preparation facility in Val D’Or, Quebec, for standard sample preparation (code PRP92) which includes drying at 105°C, crushing to 90% passing 2 mm, riffle split 500 g, and pulverize 85% passing 75 microns. The pulps are then shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples are homogenized and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (code GE_ICM91A50). The reported Li grade will be multiplied by the standard conversion factor of 2.153 which results in an equivalent Li₂O grade. Drill core was saw-cut with half-core sent for geochemical analysis and half-core remaining in the box for reference. The same side of the core was sampled to maintain representativeness.

A Quality Assurance / Quality Control protocol following industry best practices was incorporated into the sampling program. Measures include the systematic insertion of quartz blanks and certified reference materials (CRMs) into sample batches at a rate of approximately 5% each. Additionally, analysis of pulp-split and reject-split duplicates was completed to assess analytical precision. The QP has verified the QA/QC results of the analytical work.

ABOUT Q2 METALS CORP.

Q2 Metals is a Canadian mineral exploration company focused on the Cisco Lithium Project located within the greater Nemaska traditional territory of the Eeyou Istchee, James Bay, Quebec, Canada.

Cisco is comprised of 801 claims, totaling 41,253 hectares, with the main mineralized zone just 6.5 km from the Billy Diamond Highway, which transects the Project and leads to the Town of Matagami, rail head of the Canadian National Railway, approximately 150 km to the south.

The Cisco Project has district-scale potential with an initial Exploration Target estimating a range of potential lithium mineralization of 215 to 329 million tonnes at a grade ranging from 1.0 to 1.38% Li₂O, based only on the first 40 holes drilled. An Exploration Target is used to provide a conceptual estimate of the potential quantity and grade of a mineral deposit, based on known and additional limited geological evidence. It is an early-stage assessment that will help to guide further exploration, but it is not a mineral resource or mineral reserve and should not be treated as such.

Drill testing continues with mineralization open at depth and along strike with potential for expansion at the Cisco Mineralized Zone. The 2025 Exploration Program is ongoing, with rolling assay results anticipated in the coming weeks and months as the Company works towards an initial mineral resource estimate.
