Highlights:

The largest drill program to date at the Cisco Lithium Project has begun, targeting approximately 20,000 metres of drilling over the summer months:
- Priority is on infill drilling of the main Cisco deposit area, with the objective of converting the existing Inferred mineral resource to the Indicated category.
- Significant expansion drilling is also planned in and around the 2026 Exploration Target area to test potential extensions to the Cisco Deposit.
- Regional exploration drilling on additional untested high-priority targets, including the CO2 outcrop to the east of the main deposit area is planned.
Preparation of a Preliminary Economic Assessment is underway and will be based on the April 2026 Inferred Mineral Resource Estimate.
Advanced metallurgical test work is in progress, with results expected in the coming months.
Assays remain pending on nine drill holes from the 2026 winter drill program.

VANCOUVER, British Columbia, June 25, 2026 (GLOBE NEWSWIRE) -- Q2 Metals Corp. (TSX.V: QTWO | OTCQB: QUEXF | FSE: 458) (“Q2” or the “Company”) is pleased to announce the launch of the 2026 summer drill program (the “2026 Summer Drill Program”) at the Cisco Lithium Project (the “Project” or the “Cisco Project”), located within the greater Nemaska traditional territory of the Eeyou Istchee James Bay, Quebec, Canada.

Drilling commenced on June 17, 2026, with two diamond core drill rigs. Two additional rigs will start drilling over the course of the next week, and as the 2026 Summer Drill Program progresses, additional drill rigs may be mobilized to accelerate the work program. Approximately 20,000 metres (“m”) of infill and exploratory drilling is planned, focusing 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.

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.

On April 20, 2026, the Company announced an Inferred Mineral Resource Estimate on the Cisco Project (the “MRE”) which outlined a pit-constrained resource of 270 million tonnes (“Mt”) 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 “Cisco Deposit”).

Alicia Milne, President and CEO of Q2 Metals, stated, "Q2 is focused on the continued advancement of the Cisco Project through the next stages of development. With the completion of our Inferred Mineral Resource Estimate in April, we have established a globally significant lithium deposit and are now turning our attention to the next major milestone, our initial Preliminary Economic Assessment. This study will provide the first comprehensive evaluation of Cisco's development potential and economics, representing another important step toward unlocking the project's long-term value. Backed by a strong treasury of more than $70 million, we are well positioned to execute these programs and continue advancing Cisco across technical, environmental, metallurgical, engineering and permitting workstreams."

“We have a busy summer ahead as we continue advancing the Cisco Project toward development. Our primary focus is infill drilling designed to upgrade the Mineral Resource from the Inferred to the Indicated category, an important step in supporting future engineering and economic studies. In parallel, baseline environmental work commenced in May, and Phase 2 of our metallurgical program is now underway. This work is designed to confirm the positive results from Phase 1 while evaluating recovery variability across different pegmatite textures, assessing the impact of wall-rock dilution on lithium recovery and iron content, and completing flotation trade-off studies to optimize recoveries under a range of process flowsheets,” said Neil McCallum, Vice President of Exploration.

“During the 2026 Winter Drill Program, we completed approximately 10,515 metres across 19 drill holes, with the majority focused on infill drilling. Assay results for the remaining nine holes are pending and will continue to inform our understanding of the deposit as we work toward resource conversion and project advancement.”

Regional Exploration Program

Extensive regional greenfield exploration, including indicator mineral till sampling and geochemical soil sampling, expanded prospecting, and mapping is underway at the Cisco Project.

Surface channel sampling is currently being conducted across the CO1 discovery outcrop and several southern outcrop areas exhibiting extensive pegmatite exposure. The objective of the program is to collect detailed, resource-definition-quality surface data to complement the drilling program and enhance geological interpretation of the deposit.

Preliminary Economic Assessment

The preparation of a Preliminary Economic Assessment (“PEA”) is ongoing and expected to be announced in the Fall, 2026. The purpose of the PEA will be to provide an early-stage, high-level evaluation of the economic potential and financial viability of the Cisco Project. The PEA will establish the first economic benchmark for the Cisco Project by evaluating the existing MRE within a preliminary mine plan and processing flowsheet while also incorporating metallurgy test work and infrastructure studies that have been undertaken to date. The PEA will provide an initial set of project metrics, including capital intensity, operating cost, mine life, economic sensitivities and optimization opportunities.

Environmental Baseline Studies and Permitting

Baseline environmental studies were initiated in May 2026 at the Cisco Project and across the broader area, as the Company continues to advance the Cisco Project. The baseline program is designed to establish a comprehensive understanding of existing environmental conditions in and around the project and area, supporting future project planning, permitting, engineering, and stakeholder engagement.

The environmental baseline program will include studies of key environmental components such as water, wetlands, vegetation, wildlife, fish habitat, and other site-specific environmental conditions. These studies will provide the scientific foundation required to inform project design, identify potential environmental sensitivities, and support the Company’s commitment to advancing Cisco in a responsible, transparent, and collaborative manner.

Cisco Option Agreement

Under the terms of the Cisco Option Agreement dated February 28, 2024, and amended June 12, 2024 (the “Option Agreement”), the second anniversary payment consisting of the issuance of 10,000,000 common shares and the payment of $400,000 cash has been made. As well, with the filing by the Company of a National Instrument 43-101 (“NI 43-101”) compliant Inferred Mineral Resource Estimate on the Cisco Project (see news release dated April 20, 2026) which defined a total of 295 million tonnes at 1.36% Li₂O, a discovery bonus payment was also triggered. As such, 796,178 common shares were issued to the project vendor. All issued shares are subject to a hold period in accordance with applicable securities laws.

ABOUT Q2 METALS CORP.

Q2 Metals is a Canadian mineral exploration company focused on advancing the Cisco Lithium Project, located within the greater Nemaska traditional territory of the Eeyou Istchee, James Bay region of Quebec, Canada. The Cisco deposit is 6.5 km from the Billy Diamond Highway, which leads to rail facilities in the Town of Matagami, ~150 km to the south and deep seaports beyond.

The Inaugural Inferred Mineral Resource Estimate on the Cisco Lithium Project (“MRE”) defines a pit constrained 270 Mt at 1.36% Li₂O Inferred at a cut-off grade of 0.4% Li₂O with an additional underground constrained MRE of 24 Mt at 1.34 Li₂O Inferred at a cut-off grade of 0.7% Li₂O, for a total combined inferred mineral resource of 295 Mt at 1.36% Li₂O. The deposit remains open along strike, with multiple additional high potential targets identified across the broader 41,253 ha project area.

The MRE is effective April 20, 2026, and was prepared in accordance with NI 43-101 standards. For additional details regarding key assumptions, parameters, and methods used to estimate the Mineral Resources, please refer to the technical report which is available under the Company’s profile on SEDAR+. Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that Mineral Resources will be converted into Mineral Reserves.
