Highlights

  • G11 Resources released an exploration presentation outlining its spring and summer 2026/27 drill program in western Tasmania.
  • Drilling at Zig Zag confirmed a phyllic alteration zone of about 90m, with the CSAMT anomaly remaining open.
  • The company's tenements straddle the Great Lyell Fault, north and south of the Mt Lyell copper mine.
  • Planned programs cover Zig Zag, Northeast Pyrite, Beatrice, Little Owen–Great Lyell and Sunrise.

G11 Resources Limited (ASX:G11) has released its 2026 exploration presentation, setting out its spring and summer drill program for 2026/27 across its copper-gold projects in western Tasmania. The presentation focuses on the Sedgwick Bluff project and Zig Zag Hill drilling, along with a pipeline of targets along the Great Lyell Fault and in the Mt Read Volcanics.

Strategic Position Along the Great Lyell Fault

G11's Tasmanian tenements straddle the Great Lyell Fault, to the north and south of Sibanye-Stillwater's Mt Lyell copper mine, with the Henty mine located on the same trend. The company notes that the fault strikes for about 4km on EL11/2025 and describes it as a strike extension of Mt Lyell. Sibanye-Stillwater approved the restart of Mt Lyell in September 2026, with first ore expected in 2029.

G11's first Tasmanian exploration licence was granted in January 2026. The company has since acquired the Linda and MRV tenements, adding 119km², and secured EL10/2026, which sits immediately south of the Hellyer and Que River polymetallic deposits. The company states its ground is 100% owned and free of royalties.

Zig Zag Drilling and Priority Targets

Between February and August 2026, G11 completed 2,453m of diamond drilling across two holes at Zig Zag. The drilling confirmed a phyllic alteration zone of about 90m with silver, arsenic, antimony and molybdenum pathfinders. Hole SD2602 intersected silica-sericite-pyrite alteration from about 1,089m downhole and returned 15m at 1.4ppm silver from 1,115m. The CSAMT anomaly remains open up-dip and down-dip, and three follow-up holes have been designed from a new pad to the north.

At Northeast Pyrite, located about 4.0km north of Mt Lyell's northernmost deposits, strong IP chargeability coincides with altered felsic volcanics. Three holes have been designed, with up to $120,000 in Tasmanian Government co-funding available. At Beatrice, a Rosebery-style target undrilled since 2000, five diamond holes are planned to test 1km of the Itat Creek Fault, with drilling expected to begin in late November 2026, subject to approval.

Further Tasmanian Targets and NSW Projects

At Little Owen–Great Lyell, a southern extension of the fault, up to six diamond holes are planned to test Henty-style gold targets. At the Sunrise target on the Linda tenement, a diamond hole testing an untested airborne EM conductor was paused due to poor ground conditions, with drilling expected to resume by mid-November using a new contractor and rig.

In New South Wales, work continues at Packsaddle to define a maiden drill target at Kings Hill, where a gravity anomaly coincides with a magnetic feature under shallow cover. At Koonenberry, the company holds a conceptual Exploration Target at Wilandra, where drilling confirmed 4km of copper mineralisation that remains open. The company notes this is an Exploration Target and not a Mineral Resource. G11 held $4.9 million in cash at 30 June 2026.

Key Takeaways

  • G11 holds a strategic land position along the Great Lyell Fault close to the Mt Lyell copper mine.
  • Zig Zag drilling confirmed a large alteration system that remains open for follow-up testing.
  • A multi-target drill program is planned across Tasmania for the 2026/27 season, subject to approvals.
  • The company also continues work at its 100%-owned NSW copper projects.
