VANCOUVER, British Columbia, May 27, 2026 (GLOBE NEWSWIRE) -- Q2 Metals Corp. (TSX.V: QTWO | OTCQB: QUEXF | FSE: 458) (“Q2” or the “Company”) is pleased to announce the commencement of the 2026 Summer Exploration 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 region of Quebec, Canada. The Cisco Project is strategically located just 6.5 kilometres (“km”) 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 sea ports beyond.

The current Inferred Mineral Resource Estimate on the Cisco Project (the “MRE”) outlines 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”), making the Cisco Deposit the largest hard rock lithium deposit in the western hemisphere and currently fourth largest, globally. The MRE is effective April 20, 2026 and was prepared in accordance with NI 43-101 standards*. 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.

The Cisco Deposit remains open along strike, with several additional high-priority targets in the immediate area, and high exploration potential across the broader 41,253 hectare (“ha”) project area.

Alicia Milne, Q2 President and CEO, stated: “2026 has already been a transformational year for Q2 Metals and one that will see us achieve two key benchmarks in our continuing evolution. Just last month, we moved from early exploration to resource-stage, with our inaugural Inferred MRE positioning Cisco among the world’s leading spodumene lithium projects. Now, with the successful completion of a $70 million dollar bought deal financing backed by strong institutional support validating our vision for Cisco, we are embarking on our next phase of growth with significant momentum against the backdrop of a strong lithium market. We are launching our most ambitious exploration program to date, accompanied by advanced metallurgy, environmental baseline studies and road permitting, and with an inaugural PEA expected this fall.

“The Cisco Project is increasingly being recognized as a premier lithium asset, distinguished by its exceptional scale and grade, strategic location, favourable jurisdiction and outstanding access to transportation and infrastructure. We expect an extremely busy and productive year ahead as we advance the Cisco Project.”

Neil McCallum, Q2 VP Exploration and Director, said: “We have now transitioned our focus toward expansion and infill drilling aimed at upgrading portions of the current Mineral Resource Estimate from the Inferred category to Indicated. The MRE established the Cisco Project as a leading spodumene pegmatite asset while also highlighting the substantial exploration upside and discovery potential that exists across the broader project area. Importantly, the Cisco Deposit remains open in all directions and several known spodumene pegmatite outcrops in and around the Cisco Deposit have yet to be drill tested, reinforcing the potential for continued resource growth.

“In parallel, we have commenced our baseline environmental studies and advanced metallurgical test work as part of our ongoing efforts to support the continued advancement and development of the Cisco Project.”

2026 Summer Exploration Program

Infill and Exploration Drill Program

A program of approximately 20,000 metres (“m”) of infill and exploratory drilling is planned for the 2026 Summer Drill Program. The focus for June through September will be on infill drilling of the Cisco Deposit to convert and advance the resource towards an Indicated classification.

Priority targets of potential zones of high-grade and/or near surface mineralization within the Cisco Deposit as well as near-deposit expansion drilling is planned. Drill testing prospective targets around the CO2 outcrop as well as the southern portion of the deposit area are also planned.

Drilling will commence mid-June 2026 with the four diamond core drill rigs that are currently at site. Two additional rigs will be mobilized mid-summer to enhance the work program. The drilling is intended to inform an update to the MRE as the Company advances the Inferred resource toward an Indicated classification.

A successful 2026 winter drill program was completed in April with a total of 19 holes being drilled across 10,159 m. Assays remain pending on all drill holes from the Winter Drill Program.

To date, a total of 93 holes for 42,119 m have been drilled at the Cisco Project.

Regional Exploration Program

The Cisco Project comprises a large mineral claim package covering 41,253 ha within a greenstone belt that extends approximately 30 km in strike length. Spodumene-bearing LCT-type pegmatites, such as those at the Cisco Deposit, are commonly associated with greenstone belts, including the Frotet–Evans Greenstone Belt in this case. Observations from analogous greenstone belts worldwide demonstrate that these pegmatite systems frequently occur in clusters along favourable stratigraphic and structural corridors, rather than as isolated occurrences. This geological context supports the Company’s continued focus on regional exploration across the broader Cisco claim package (Figure 2).

Since acquiring the Cisco Project in 2024, exploration activities have been primarily focused on the immediate area surrounding the current Cisco Deposit, with only limited preliminary work completed across the broader regional Project area. Extensive regional greenfield exploration, including indicator mineral till sampling and geochemical soil sampling, expanded prospecting, and mapping is now underway.

Preliminary Economic Assessment

The preparation of a Preliminary Economic Assessment (“PEA”) has commenced. 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 be based on the current MRE as well as metallurgy test work that was completed in 2025 and additional infrastructure studies that the Company has undertaken to date. It is expected that the PEA will be published in the Fall, 2026.

2026 Metallurgy Program

Phase 1 of the metallurgical test work was completed on three composite samples using Heavy Liquid Separation (“HLS”) to confirm the suitability of a Dense Media Separation (“DMS”) process.

Phase 2 of the metallurgical test work is underway. An expanded sampling and testing program has been designed to confirm the results of Phase 1 and test the variability of the recoveries across all pegmatite textures. The test work will include wall-rock dilution to understand to what extent its introduction affects recovery and iron content.

Flotation test work will be added to complete the necessary trade-off studies to understand the extent to which recoveries can be improved and utilizing different flowsheets.

Environmental Baseline Studies and Permitting

Baseline environmental studies have been initiated at the Cisco Project and across the broader area, marking an important step in the Company’s transition from exploration success toward responsible project advancement. 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.

Permit applications for a new camp and an access road from the Billy Diamond Highway to the Cisco Deposit area were submitted in January.
