GreenLight Metals (TSX-V:GRL) has intersected massive to semi-massive sulphides in two step-out holes at its Bend Copper-Gold Project in Wisconsin, US, with assays pending to establish metal grades.
Hole B26-015 intersected a 24.52m interval from 428.55m, approximately 50m east of an earlier drill section. Follow-up hole B26-016 intersected a 31.62m interval from 468.12m, testing the interpreted copper zone trend 55m further down-dip.
Both intervals contain pyrite and chalcopyrite, alongside a narrow tuff interbed in B26-015 and a quartz vein in B26-016. Estimated true thicknesses are approximately 80% and 70% of drilled lengths, respectively.
Separately, assays from B26-012 returned 55.9m @ 0.88 grams per tonne gold (Au) from 446.5m, including 14.87m @ 2.65g/t Au and, within that interval, 6.91m @ 4.38g/t Au.
True thickness is estimated at 65–70% of drilled length. Hole B26-014, which tested the copper zone’s up-dip limits, returned no significant assays.
President and CEO Matt Filgate says the results support further exploration at Bend.
“The recurrence of pyrite and chalcopyrite in these step-out holes is particularly encouraging and gives us a clear direction for follow-up drilling,” Filgate says.
“B26-012 also adds a broad gold-bearing intersection with a higher-grade interval at depth.”
October completion targeted
GreenLight is targeting approximately 6,800m within its permitted 7,000m program, with completion expected in October.
Drilling continues in B26-017, while planned hole B26-018 will test the transition between copper-zone and gold-dominant mineralisation, alongside a borehole electromagnetic target.
Results will guide winter 2026–27 drilling, subject to required authorisations. GreenLight says two of six federal environmental review and permitting processes were complete as of 20 September, with overall completion estimated for the March quarter 2027.
The Wisconsin campaign follows an agreement allowing Barrick Mining (NYSE:B), through its subsidiary, to earn up to 80% of GreenLight’s Kalium Canyon Gold Project in Nevada, US. The arrangement allows GreenLight to retain exposure to Kalium Canyon while directing its own capital towards Wisconsin.
GreenLight Metals is an explorer advancing assets in the US, including Wisconsin’s Bend and Reef projects and the Lobo and Lobo East targets, alongside Kalium Canyon in Nevada.
