Key Highlights
- Diamond drilling has started at the Elizabeth Springs East Prospect within the 100%-owned Diamantina Copper-Gold Project in western Queensland.
- The two-hole program totals about 1,500m and follows historical hole DTD002, which returned 161m @ 0.4% Cu and 0.11g/t Au from 449m.
- The first hole, about 800m long, is partly funded by a $275,000 Queensland Government Collaborative Exploration Initiative grant.
- Historical drilling covers only an 800m x 800m area inside a 4km x 2km coincident magnetic and gravity anomaly.
Strategic Energy Resources Limited (ASX:SER) has started diamond drilling at the Elizabeth Springs East (ESE) Prospect, part of its 100%-owned Diamantina Copper-Gold Project, which sits 280km south of Cloncurry in western Queensland. The program consists of two holes totalling about 1,500m and is designed to test for extensions to copper-gold and copper-nickel mineralisation found in earlier drilling. It is the third and final leg of the company's back-to-back 2026 field season, following diamond programs at the Canobie Copper Project and the Bulimba Gold Project.
Two Holes Aimed at Known Mineralisation
The first diamond hole is planned at roughly 800m and will be drilled to the east beneath coiled tube hole DCT010. That hole returned 6.5m @ 0.52% Cu and 0.16% Ni from 423m and sits approximately 500m south-west of DTD002. Because the coiled tube rig sampled only the top of basement, the polymict sulphide breccia in DCT010 has never been tested at depth. Petrophysical testing showed the breccia to be conductive, so a down-hole electromagnetic survey will be run to look for off-hole conductors.
DCT010 is the only hole at ESE to have intersected polymict sulphide breccia with an elevated copper-nickel signature. Petrology and scanning electron microscope work identified a later, porous hydrothermal pyrite phase enriched in copper and nickel, interpreted as a variant of the known Mt Isa iron oxide copper-gold (IOCG) model.
The second hole will step out from DTD002 to test for extensions of the high-grade copper-gold zone, guided by geophysical data that was reprocessed and remodelled during the company's technical review earlier in 2026.
What DTD002 Returned at Elizabeth Springs East
DTD002 was the first hole drilled by Anglo American at ESE, targeting a high gravity feature 400m south of ES-08-02, the 2008 hole drilled by Red Metal Limited that intersected IOCG alteration with low levels of elevated copper. DTD002 recorded 161m @ 0.4% Cu and 0.11g/t Au from 449m, associated with a magnetite-rich IOCG alteration assemblage.
Within that interval sits 17.3m @ 1.76% Cu and 0.37g/t Au from 465.3m, made up of intense magnetite alteration with chalcopyrite-bearing veins. Narrower zones inside it include 0.21m @ 8.3% Cu and 8.27g/t Au from 465.89m and 0.67m @ 25.6% Cu and 1.29g/t Au from 482m.
DTD006b, drilled 80m away, intersected 87.3m @ 0.30% Cu and 0.16g/t Au from 489.7m, while DTD005b recorded 13.2m @ 0.44% Cu and 0.11g/t Au from 545.8m.
Project Footprint and Work Since Acquisition
Most drilling at ESE sits inside an 800m x 800m area, within a 4km x 2km coincident magnetic and gravity anomaly, so the larger part of the prospect has not been drill tested. The Diamantina Project comprises two granted exploration licences, EPM27134 and EPM27135, plus four adjoining applications, EPM29278 to EPM29280 and EPM29305. Together they cover more than 1,800km2 of the projected undercover southern extension of the Mt Isa Eastern Fold Belt, bounded to the west by the Pilgrim Fault.
SER announced the 100% acquisition from Anglo American in July 2025, so drilling starts 15 months after the company secured the project. Since then it has lodged the four licence applications, secured the $275,000 grant and completed a technical review of all historical datasets, which identified a new, untested magnetic anomaly in the far west of the project.
Where the Field Season Stands
With the rig now turning at Elizabeth Springs East, SER has drill programs under way or completed across three Queensland projects in 2026: Diamantina, the Canobie Project held in joint venture with FMG Resources, and the Bulimba Gold Project held in joint venture with Sumitomo Metal Mining Oceania. Managing Director Dr David DeTata said the first hole targets the never-tested copper-nickel breccia at the base of DCT010 and the second seeks to extend known high-grade copper-gold mineralisation. Assay results for all three projects are due over the coming months.
