Q2 Metals Drills 457 Metres of Continuous Spodumene Pegmatite, Widest Interval to Date at the Cisco Lithium Project in Quebec, Canada

Highlights

• Drill hole CS25-044 encountered three (3) spodumene pegmatite intervals, with the widest continuous interval of 457.4 metres, along with an additional 36.9 metre interval.
  
  
• Drill hole CS25-038 encountered 22 spodumene pegmatite intervals, including a 58.9 metre wide interval, along with a further 58.3 metre and 31.8 metre interval.
  
  
• Drill hole CS25-039 encountered 13 spodumene pegmatite intervals, including a 108.5 metre wide interval, along with a further 99.7 metre, 77.7 metre and 71.0 metre interval.
  
  
• Drill hole CS25-040 encountered 12 spodumene pegmatite intervals, including a 95.1 metre wide interval, along with a further 81.9 metre and 66.5 metre interval.
  
  
• A total of 46 holes for 20,138 metres have been drilled on the Cisco Project to date, with assays pending on the eight (8) holes drilled during the summer 2025 drill campaign.
  
  
• Three (3) drill rigs are currently operating on the Cisco Project, primarily focused on infill scale spacing of the main mineralized zone, as the Company works towards an initial inferred Mineral Resource estimate.
  
  

VANCOUVER, British Columbia, Sept. 10, 2025 (GLOBE NEWSWIRE) -- Q2 Metals Corp. (TSX.V: QTWO | OTCQB: QUEXF | FSE: 458) (“Q2” or the “Company”) is pleased to announce an update from the summer 2025 infill drilling campaign (the “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.

Multiple wide intercepts of continuous spodumene pegmatite were encountered within the eight (8) holes drilled, for a total of 4,603 metres (“m”), during the Summer Drill Program that launched mid-June. All eight (8) holes intercepted pegmatite with visual indications of spodumene mineralization identified.

“Hole 44, with its 457-metre-long intercept, has far exceeded our expectations. The Mineralized Zone also remains open at depth and along strike and there remains potential for significant expansion. Our geology team has designed a robust drilling campaign for the fall & winter as we continue to define the Mineralized Zone and work towards an inferred Mineral Resource estimate,” said Neil McCallum, Q2 Metals Vice President of Exploration.

“The visual results from our Summer Drill Program are giving us a clearer picture of the Mineralized Zone at Cisco,” said Alicia Milne, President and CEO of Q2 Metals. “The scale and consistency of the spodumene-bearing pegmatite intercepted to date reinforces the long-term potential of the Cisco Project. With a strong treasury in place, we are well positioned to continue our drill campaign and advance our strategy to unlock the full value of Cisco.”

Summary of Spodumene-Bearing Pegmatite Intervals

The pegmatite intervals (greater than 2 m) of drill holes CS-25-038 to 045 are reported below in detail (Table 1):

Table 1. Summary of Spodumene-Pegmatite Intervals at the Main Zone, Cisco Project

The mineralized intervals in each of 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 CS25-038 to CS25-045 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

The summer drill program was designed to continue to drill within the main mineralized zone that spans approximately 1.5 kilometres (“km”) northeast-southwest trending mineralized strike length identified at the Cisco Project (the “Mineralized Zone”) (Figures 2, 3, 4 and 5).

An Exploration Target, prepared for the Company by independent consultant BBA Inc., encompassed the Mineralized Zone and included 40 holes completed for 16,167.8 m as at July 21, 2025 ¹. The estimated range of potential mineralization and grade at the Mineralized Zone is from 215 to 329 million tonnes (“Mt”) at a grade ranging from 1.0 to 1.38 % Li₂O (see press release of July 21, 2025).

An Exploration Target is used to provide a conceptual estimate of the potential quantity and grade of a mineral deposit, based on known and additional limited geological evidence. It is an early-stage assessment that will help to guide further exploration, but it is not a mineral resource or mineral reserve and should not be treated as such.

The potential quantity and grade of the Exploration Target on the Cisco Project 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 Project (“NI 43- 101”), and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.
