Q2 METALS INCREASES DRILL ACTIVITY AND PROVIDES EXPLORATION UPDATE ON THE CISCO LITHIUM PROJECT IN QUEBEC, CANADA

Q2 Metals Corp. has provided an update on exploration and drilling activities at the Cisco lithium project, located within the greater Nemaska traditional territory of the Eeyou Istchee James Bay region of Quebec, Canada.

Following the completion of a $26-million flow-through private placement financing on Aug. 14, 2025, the company has expanded its exploration program at the Cisco project.

Highlights:

• $26-million flow-through financing completed in August, 2025;
• Drilling at the Cisco project has been continuing since June, 2025, and a total of 46 holes for 20,138 metres has been drilled to date; assays are pending on all drill holes completed this summer;
• Three drill rigs are currently operating at Cisco, with a fourth expected to commence operations in November;
• Current drilling is focused on infill scale spacing of the main mineralized zone as the company works toward an initial inferred mineral resource estimate at Cisco;
• Additional metallurgical test work is continuing;
• Regional geological sampling and mapping work continues.

"Strong institutional support enabled us to complete the $26-million financing in August, which has allowed us to significantly ramp up activities at Cisco," said Alicia Milne, president and chief executive officer of Q2 Metals. "These funds have enabled Q2 to greatly accelerate our drill program, continue regional mapping and sampling programs, and expand on metallurgical test work. With three drill rigs now operating, our immediate focus is to advance the Cisco project towards an initial inferred mineral resource estimate."

Drilling

The primary objective of the 2025 summer drill program has been infill drilling of the 1.5-kilometre northeast-southwest-trending mineralized strike length identified at the Cisco project utilizing one drill rig. The drill program commenced in June, 2025, and has now been expanded, with three drill rigs currently operating, with a fourth drill rig anticipated to commence operations in November, 2025.

BBA Inc., an independent consultant to the company, prepared an exploration target on the mineralized zone (see news release of July 21, 2025). The exploration target estimated a range of lithium mineralization at the Cisco project of 215 million to 329 million tonnes at a grade ranging from 1.0 per cent to 1.38 per cent Li2O (lithium oxide). The potential quantity and grade of the company's exploration target are conceptual in nature. There has been insufficient exploration to estimate and define a mineral resource, as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

The expanded drill program has been designed to tighten the drill spacing within the mineralized zone as the company works toward an initial inferred mineral resource estimate at the Cisco project. A portion of the expanded drill program will also test additional outcrop zones with the aid of the geophysical targeting.

Metallurgy

Preliminary metallurgical test work was performed by SGS Canada Inc. on drill core samples collected during the company's 2024 drill program (see news release of Aug. 20, 2025). The results of the first phase of metallurgical test work confirmed that strong recoveries could be achieved with a DMS (dense media separation) circuit.

A second phase of metallurgy test work to expand upon the first-phase results is currently being designed and is expected to commence in September, 2025.

Regional mapping and sampling

The Q2 geology team is continuing a regional mapping and sampling program across the Cisco project. The regional program assessed additional areas of interest across the broader 41,253-hectare claim package, with the objective of identifying and refining targets for further exploration. Rock samples have been submitted to the laboratory and are pending.

Orientation-style geophysical surveys were conducted over a portion of the mineralized zone and additional drill validation will be conducted to determine if they are a suitable method of guiding exploration. If these prove successful, additional geophysical surveys will be conducted near the currently known mineralized areas.

Coming events

Q2 Metals is hosting a site tour at the Cisco project mid-month and attending the following conferences and events.

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.

The Cisco project comprises 801 claims, totalling 41,253 hectares, with the main mineralized zone just 6.5 kilometres from the Billy Diamond Highway, which transects the project. The town of Matagami, railhead of the Canadian National Railway, is 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 and grade of 215 million to 329 million tonnes at a grade ranging from 1.0 per cent 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. There has been insufficient exploration to estimate and define a mineral resource, as defined by NI 43-101, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

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 continuing, with rolling assay results anticipated in the coming weeks and months as the company works toward an initial mineral resource estimate.

Sampling, analytical methods and quality assurance/quality control protocols

All drilling is conducted using a 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 500 grams and pulverizing 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 has been 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.
