Cisco lithium summer programme continues with four rigs

Q2 Metals has returned 137.6 metres at 1.47% Li2O from hole CS26-088 at the Cisco Lithium Project in Quebec. That interval included 40.6 metres at 3.25% Li2O and 93.6 metres at 1.23% Li2O.

The assays form the final analytical results from the winter portion of the 2026 drill programme at Cisco, which sits in the southernmost part of James Bay within the greater Nemaska traditional territory of the Eeyou Istchee.

Cisco is about 6.5 kilometres from the paved Billy Diamond Highway. The road links the project to rail infrastructure at Matagami, about 150 kilometres to the south, with onward access to deep seaports on the St. Lawrence River.

The 2026 winter campaign completed about 10,515 metres across 19 drill holes. Results for drill hole 93 are still pending because the hole was not completed before the winter programme ended.

Other standout assays came from hole CS26-092, which cut 185.7 metres at 1.54% Li2O and a separate 73.5 metres at 1.54% Li2O. Hole CS25-086 returned 10 separate mineralised intervals, including 50 metres at 1.58% Li2O.

Additional winter holes also delivered broad intervals. CS25-083 returned three separate intervals, including 73.5 metres at 1.34% Li2O. CS26-087 returned nine intervals, including 46.9 metres at 0.97% Li2O.

Meanwhile, hole CS26-089 reported 10 separate intervals, including 21.6 metres at 1.63% Li2O. Hole CS26-090 delivered nine intervals, including 43.1 metres at 1.46% Li2O, 42.8 metres at 1.17% Li2O and 40.7 metres at 0.87% Li2O.

Neil McCallum, Q2 Metals vice president of exploration, said the final winter assays continued to show the scale and consistency of the Cisco deposit.

According to McCallum, high-grade intercepts in CS26-088 and mineralisation beyond the limits of the April 2026 inferred mineral resource estimate support the view that Cisco is still growing. He added that the summer campaign is targeting resource conversion and testing high-grade and near-surface expansion opportunities.

The 2026 summer drill programme is now in progress with four drill rigs operating at site. Q2 Metals also has a Preliminary Economic Assessment in preparation, based on the inferred mineral resource estimate announced in April 2026.

That April 2026 estimate outlined a pit-constrained inferred resource of 270 million tonnes grading 1.36% Li2O at a 0.4% Li2O cut-off grade. It also included an underground-constrained inferred resource of 24 million tonnes grading 1.34% Li2O at a 0.7% Li2O cut-off grade, for a combined inferred resource of 295 million tonnes grading 1.36% Li2O.
