Q2 METALS INTERCEPTS 457.4 METRES OF 1.65% LI2O IN DRILL HOLE 44 AT THE CISCO LITHIUM PROJECT

Q2 Metals Corp. has released analytical results from the continuing 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.

Highlights:

• CS25-044 -- two separate intervals, including 457.4 metres at 1.65 per cent Li2O (lithium oxide) and 36.9 m at 1.65 per cent Li2O;
• Drill hole CS25-044 is the widest continuous spodumene pegmatite interval drilled by Q2 to date;
• Infill drilling for incorporation into the initial mineral resource estimate on the Cisco lithium project, expected in Q1 2026, will be completed in the coming weeks;
• The four drill rigs currently operating on the Cisco lithium project will pause mid-December and resume in early January.

"Drill hole 44 further showcases the Cisco project as a globally significant hard-rock lithium discovery. The results to date will underpin the inaugural mineral resource estimate, which we expect to announce in the first quarter of 2026, as we continue to advance Cisco," said Alicia Milne, president and chief executive officer for Q2 Metals. "I am proud and grateful for the tireless efforts of our team, which have enabled us to consistently achieve the goals and milestone targets we publicly set for the company."

"The standout result from our drilling to date has clearly been drill hole 44. Not only did hole 44 have extraordinary width and grade, but it has significant intervals occurring outside the previously defined bounds of the mineralized zone defined by the exploration target (ET)," said Neil McCallum, vice-president of exploration for Q2 Metals. "Given our success at the drill bit to date, we are very excited for subsequent assay results, particularly from holes CS25-063 and CS25-065, which also intercepted significant mineralization outside the ET boundaries and further expand and define Cisco's already-impressive footprint."

The analytical results reported herein represent 2,200.4 metres of drilling over four drill holes completed during the 2025 drill program. Pegmatite intervals and analytical results from the current program will be reported as they are received and reviewed.

All intervals of greater than two metres of core length and greater than 0.30 per cent Li2O are included in Table 1. Internal dilution of non-pegmatite material was limited to intervals of less than three metres. 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.

The primary focus of the fall and winter drilling campaign is on infill-scale drilling within the main mineralized zone defined by the ET, issued by the company in July, 2025. The exploration target estimated a range of potential lithium mineralization at the mineralized zone of 215 million to 329 million tonnes at a grade ranging from 1.0 to 1.38 per cent Li2O and was 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.

The drill campaign has been designed to support the company's objective of delivering an initial inferred mineral resource estimate in the first quarter of 2026. Drilling at the Cisco project is continuing, with four drill rigs currently operating on site.

Coming events

Members of the Q2 team are currently attending the Mines & Money Resourcing Tomorrow (booth No. D35) conference being held in London, United Kingdom from Dec. 2 to Dec. 4, 2025.

Sampling, analytical methods and quality assurance/quality control 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, Que., for standard sample preparation (code PRP92) which includes drying at 105 C, crushing to 90 per cent passing two millimetres, riffle splitting to 500 grams and pulverizing to 85 per cent passing 75 microns. The pulps are then shipped by air to SGS Canada's laboratory in Burnaby, B.C., where the samples are homogenized and subsequently analyzed for multielement (including lithium and tantalum) using sodium peroxide fusion with ICP-AES/MS finish (code GE_ICM91A50). The reported lithium 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 QA/QC 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 per cent each. Additionally, analysis of pulp-split and reject-split duplicates was completed to assess analytical precision. The qualified person has verified the QA/QC results of the analytical work.

Qualified person

Mr. McCallum has reviewed and approved the technical information in this news release. Mr. McCallum is a director and the vice-president, exploration, for Q2.

About Q2 Metals Corp.

Q2 Metals is a Canadian mineral exploration company focused on the Cisco lithium project, which is located within the greater Nemaska traditional territory of the Eeyou Istchee, James Bay region of Quebec, Canada. The known mineralized zone at Cisco is just 6.5 kilometres from the Billy Diamond Highway, which leads to the railhead in the town of Matagami, approximately 150 kilometres to the south.

The Cisco project has district-scale potential with an initial exploration target estimating a range of potential lithium mineralization of 215 million to 329 million tonnes at a grade ranging from 1.0 to 1.38 per cent Li2O, based only on the first 40 holes drilled. It is noted that the potential quantity and grade of the exploration target are conceptual in nature and there has been insufficient exploration to estimate and define a mineral resource, as defined by NI 43-101. It is uncertain if further exploration will result in the target being delineated as a mineral resource.

The 2025 exploration program is continuing, prioritizing infill drilling toward an initial mineral resource estimate expected in Q1 2026. Expansion and exploration drilling continues at the main zone, which remains open at depth and along strike, as well as at high-potential targets identified across the broader 41,253-hectare project area.
