Breakthrough Minerals Ltd (ASX:BTM) released an ASX announcement on 15 September 2026 detailing further high-grade copper-gold assay results from resource expansion drilling at the Turpentine Deposit, part of the North Queensland Copper-Gold Project. Three new holes returned significant copper-gold mineralisation, with hole 26TUR009 — the northernmost hole drilled at Turpentine to date — delivering the highest-grade result from the current phase at 5m at 3.75% CuEq (3.07% Cu, 0.84 g/t Au) from 252m within a broader 14m at 1.57% CuEq intersection. Drilling is set to recommence with a reverse circulation rig targeting further northern extensions, with assays expected from early October 2026.

Latest Drill Results

Hole 26TUR004 returned 9m at 1.59% CuEq (1.36% Cu, 0.29 g/t Au) from 262m, including 5m at 2.62% CuEq (2.23% Cu, 0.48 g/t Au) from 263m. Hole 26TUR008 returned 24m at 0.46% CuEq (0.41% Cu, 0.06 g/t Au) from 271m, including 3m at 0.99% CuEq (0.82% Cu, 0.20 g/t Au) from 271m. Hole 26TUR009, the northernmost hole drilled to date, returned 14m at 1.57% CuEq (1.30% Cu, 0.34 g/t Au) from 251m, including 5m at 3.75% CuEq (3.07% Cu, 0.84 g/t Au) from 252m.

Resource and Programme Context

Every hole drilled by Breakthrough Minerals at Turpentine in the current programme has intersected copper mineralisation. Turpentine is the company's largest deposit, hosting an Inferred Mineral Resource of 8.7 Mt at 1.16% CuEq for 101,000 tonnes of contained CuEq, within the broader North Queensland Copper-Gold Project resource base of 200,000 tonnes contained CuEq. Prior standout intersections from the current programme include 26TUR002 (17m at 1.24% CuEq from 180m), 26TUR003 (19m at 1.03% CuEq from 216m), and 26TUR005 (5m at 3.21% CuEq from 137m). An RC rig will recommence drilling next week targeting further northern extensions, with approximately 2,500m of RC drilling also planned across Hazel Creek targets.

About the Company

Breakthrough Minerals Ltd is an ASX-listed copper-gold explorer developing the North Queensland Copper-Gold Project, centred on the Turpentine Deposit. The company is in active resource expansion drilling mode, with results consistently extending the mineralised system north beyond the existing resource model. Managing Director Nigel Broomham noted that the results continue to strengthen confidence in the scale and continuity of the Turpentine mineralised system.

Risks

All current Turpentine resources are Inferred — the lowest JORC confidence level. Upgrading to Indicated requires infill drilling to demonstrate geological continuity.

The northern extension drilling is in areas beyond the existing resource model. While all drilled holes have returned mineralisation, grade and continuity in new areas is not yet fully defined.

North Queensland exploration involves access, weather (wet season/cyclone risk), and environmental considerations that can affect drilling schedules.

Breakthrough Minerals is a small-cap explorer. Sustained drilling requires ongoing Capital management and potential future capital raisings.

Copper-gold resource definition requires multiple drilling campaigns before a scoping or feasibility study can be supported.

What to Watch Ahead

Assay results from the RC rig commencing northern extension drilling, expected from early October 2026.

Whether the northern extension holes confirm grade and continuity implied by 26TUR009 — material confirmation would significantly expand the resource footprint.
