Q2 Metals Corp. (TSX-V: QTWO) (OTCQB: QUEXF) (FSE: 458) is pleased to report the final analytical results from the winter portion of the 2026 drill program at the Company’s Cisco Lithium Project. The Cisco Project is located within the greater Nemaska traditional territory of the Eeyou Istchee in the southernmost part of James Bay, Quebec, Canada and is strategically located just 6.5 kilometres from the paved, all-season Billy Diamond Highway, which provides access to rail infrastructure in the town of Matagami, Quebec, approximately 150 km to the south, with connections to deep seaports along the St. Lawrence River.

Approximately 10,515 metres across 19 drill holes was completed during the 2026 Winter Drill Program, with the results reported herein representing 3,611.6 m of drilling over seven (7) drill holes. All analytical results from the 2026 Winter Drill Program have been announced, except for drill hole-93 which was not completed by the end of the winter program, and analytical results will be released as soon as they are available.

“These final results from our winter program continue to demonstrate the exceptional scale and consistency of the Cisco Deposit. The high-grade intercepts encountered in holes such as CS26-088 and the extension of significant mineralization beyond the limits of our Inferred Mineral Resource Estimate continue to reinforce our confidence that Cisco remains a growing system with substantial upside. With our largest drill campaign to date now underway, the 2026 summer program is focused on converting the current Inferred resources to the Indicated classification, as well as testing opportunities for high-grade and near-surface expansion both within and around the Cisco Deposit,” said Neil McCallum, Q2 Metals Vice President of Exploration.

“Announcing the Inferred Mineral Resource Estimate on the Cisco Project in April established Cisco as a globally significant spodumene lithium project in a mining-friendly jurisdiction with exceptional access to infrastructure,” said Alicia Milne, Q2 Metals President and CEO. “Importantly, the Cisco Deposit remains open in all directions, with significant potential for continued resource expansion and today’s results reinforce that opportunity. We continue to aggressively advance Cisco through robust exploration and drilling programs, environmental baseline studies and metallurgical test work, with the major milestone of our initial Preliminary Economic Assessment this fall.”

Drill Results Discussion

 Figure 1. Map of Drill Holes 83, 86-90 & 92 at Cisco Deposit

Drill hole-88, located 110 m northwest from hole-18 and 200 m northwest from hole-73 encountered 137.6 m at 1.47% Li₂O; including 40.6 m at 3.25% Li₂O. The results of this hole support the continued definition of a high-grade sub-zone within the main mineralized body at the Cisco Deposit.

Previous nearby drill results include:

• Drill hole-18: 215.6m at 1.69% Li₂O, including 64.6m at 2.29%Li₂O; and
• Drill hole-73: 170.2 m at 1.99% Li₂O, including 40.1 m at 2.89 % Li₂O

Drill hole-92 encountered a 185.7 m interval averaging 1.54% Li₂O, with over 100 metres of the interval extending beyond the conceptual open pit that was part of the MRE.

The remaining drill holes in this release are considered infill holes, and the results are consistent with expectations given their close spacing.

Summary of Analytical Data

 Table 1. Summary of Analytical Results of Drill Holes at Cisco Project

All intervals of greater than 5 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.

2026 Summer Drill Program

The summer portion of the 2026 drill program commenced on June 17, 2026 and four diamond core drill rigs are currently in operation.

The primary focus of the 2026 Summer Drill Program is on infill drilling of the Cisco Deposit to convert and advance the mineral resource from its current Inferred mineral resource classification to an Indicated mineral resource classification as well as exploratory drilling. Potential zones of high-grade and/or near surface mineralization within the Cisco Deposit have been identified as priority targets for drill testing. Expansion drilling proximate to the deposit and the CO2 outcrop are also planned.

Preliminary Economic Assessment

Preparation of a Preliminary Economic Assessment on the Cisco Project by BBA Inc. is ongoing. The PEA will establish the first economic benchmark for the Cisco Project by evaluating the existing Inferred Mineral Resource Estimate (announced on April 20, 2026) within a preliminary mine plan and processing flowsheet while also incorporating metallurgy test work and infrastructure studies that have been undertaken to date.

The MRE outlined a pit-constrained resource of 270 million tonnes grading 1.36% Li₂O at a 0.4% Li₂O cut-off grade and an additional underground-constrained resource of 24 Mt grading 1.34% Li₂O Inferred at a 0.7% Li₂O cut-off grade. Together, these support a combined inferred mineral resource of 295 Mt grading 1.36% Li₂O

The PEA will provide an initial set of project metrics, including capital intensity, operating cost, mine life, economic sensitivities and optimization opportunities. It is expected that the PEA will be published in Fall, 2026.

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 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.
