Highlights:
The 2025 Winter Program concluded with 6,997 metres (m) drilled across 14 holes.
Drill hole CS25-028 encountered eight (8) spodumene pegmatite intervals, with the widest interval of 50.9 m of continuous spodumene pegmatite, along with additional noteworthy intercepts of 21.5 m and 19.3 m.
Drill hole CS25-036 encountered 13 spodumene pegmatite intervals, with the widest interval of 64.3 m of continuous spodumene pegmatite, along with additional noteworthy intervals of 22.3 m, 18.1 m and 12.7 m. Hole 36 ended in pegmatite at a depth of 308.6 m due to time constraints.
Assays are pending on all 14 drill holes completed in the 2025 Winter Program.
The northeast-southwest strike of the main zone has increased to 1,500 m (previously 850 m at the end of 2024).
VANCOUVER, BC / ACCESS Newswire / April 28, 2025 / Q2 Metals Corp. (TSX.V:QTWO)(OTCQB:QUEXF)(FSE:458) ("Q2" or the "Company") is pleased to provide an update on the Winter 2025 expansion drill program ("2025 Winter Program") at the Company's Cisco Lithium Project (the "Project" or the "Cisco Project"), located within the greater Nemaska traditional territory of the Eeyou Istchee James Bay, Quebec, Canada.
The 2025 Winter Program at the Cisco Project concluded with a total of 14 drill holes for 6,997 m of drilling completed. Of the 14 drill holes completed, 10 intercepted spodumene-bearing pegmatite. Assays are pending on all 14 drill holes, and the Company anticipates the first results to be announced in May.
"We are very encouraged by the results to date, which continue to validate the scale and potential of the Cisco Project," said Q2 Metals President and CEO Alicia Milne. "With only 37 holes drilled for 14,644 metres to date, we've built a strong foundation for continued advancement. Cisco's strategic position in the southernmost part of the Eeyou Istchee James Bay region, just 150 kilometres from rail access, gives it a distinct development advantage and further enhances the project's long-term value. We remain well-funded, the project remains open in all directions and at depth, and we are eager to resume drilling in June."
"The 2025 Winter Program was highly successful," said Q2 Vice President of Exploration Neil McCallum. "During the program we nearly doubled the strike length of the main mineralized zone from 850 m to 1.5 kilometres and started to drill test other areas of interest that will require further work. On our return to the Project in June, we will continue to systematically define the known mineralized zone, starting with Hole 36 which ended due to the start of the traditional goose hunting season at 308.6 m and in spodumene pegmatite. Additional mapping and sampling of the Cisco Project will also be a priority this summer as we've explored less than 10 percent of our total land package, leaving a significant amount of the prospective 30-kilometre-long greenstone belt still to be tested."
Summary of Spodumene-Bearing Pegmatite Intervals
The pegmatite intervals (greater than 2 m) of drill holes CS-25-028 to 37 are reported below in detail (Table 1 & 2):
The mineralized intervals in all the holes are not necessarily representative of the true width and the modelled pegmatite zones are being refined with every additional hole.
Cautionary Statement: The presence of pegmatites does not confirm the presence of lithium (spodumene or other lithium minerals). Pegmatites are fractionated coarse grained igneous rocks commonly associated with lithium mineralization; however, many pegmatites do not contain mineralization. The presence of any mineralization can only be confirmed with assaying.
The geological team has completed the core cutting and logging of holes CS25-028 to CS25-037 and the samples have been dispatched to the SGS Canada preparation laboratory located in Val-d'Or, QC for mineral analysis to confirm the presence of lithium.
Discussion of Drilling Results
Three holes (CS25-029, 031 and 033) targeted the southern extension of the main mineralized zone. With the 200-metre spacing, and only a few holes per section line, wide (>100 metre) pegmatite intervals were not intercepted. It is expected that the wide pegmatite intervals are present, however additional testing work is required. It is noted that the pegmatite intervals are somewhat deeper in the drill holes at the south and further work will be carried out during the summer exploration season to test the potential up-dip location of the pegmatite towards the west. In summary, the main zone remains open to the south.
Hole CS25-030 targeted the deeper portions of the northern extent of the main mineralized zone and has demonstrated that the zone is open in that direction.
Hole CS25-028 tested the eastern portion of the main mineralized zone and provided additional information in that area. Combined with the other holes drilled to the east, the zone remains open in that direction as well.
Hole CS25-036 was not completed prior to the start of this year's goose-hunting season and ended before the intended completion depth. Despite this, the objective of the hole was accomplished with several wide pegmatite intervals intercepted that will assist in resolving the geometry of the pegmatite as well as providing guidance on definition-scale drilling. Drilling on this hole will re-commence as soon as possible after the goose-hunting season.
Drill holes CS25-032, 034, 035 and 037 were drilled to define the subsurface expression of the prominent mineralized CO2 outcrop. Additional work is needed to follow up this area as several potential orientations have not yet been tested.
Metallurgical Testing
During the 2025 Winter Program, representative samples were assembled and dispatched to SGS Canada for additional preliminary metallurgical test work, including heavy liquid separation (HLS), dense media separation (DMS), magnetic separation, and flotation.
The primary objective of the preliminary metallurgical program will be to evaluate the beneficiation of the currently defined mineralized zone at the Cisco Project with a traditional lithium pegmatite flowsheet. The goal of the proposed metallurgical work is to produce a spodumene concentrate of greater than 6% Li2O with low iron content, at a maximum lithium recovery.
Initial metallurgical testing on 16 drill core analytical pulp samples of pegmatite collected across seven (7) drill holes at the Cisco Project indicated that spodumene is the primary lithium-bearing mineral within all pegmatite samples (see news release from Q2 on February 12, 2025).
Optical Televiewer Survey Work
During the 2024 drill program conducted at the Cisco Project, optical televiewer survey work was conducted on 13 of the 17 holes drilled by the Company to confirm the pegmatite contact relationships at depth (see news release from the Company on February 3, 2025).
Following the compilation and review of the data points collected, it was determined that the orientation of the pegmatite aligns with the surface measurements, and that the drill azimuth is appropriate for this stage of the Company's drilling campaigns. Additionally, the dip of the pegmatite varies between 25- and 80- degrees (relative to the surface), indicating that the current drill angle of -45 degrees is the most appropriate angle.
The Company continued to collect downhole televiewer data during the 2025 Winter Program. Additional drill holes from the 2024 drill program were surveyed as well as several of the holes drilled in the 2025 Winter Program (drilling at hole CS25-036 was in process). Data collected will continue to refine the Company's most appropriate drilling approach.
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 (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% 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.
