Key Highlights

SER began a two-hole, about 1,500m diamond program at Elizabeth Springs East, where DTD002 previously returned 161m @ 0.4% Cu and 0.11g/t Au.
TR2 completed 72 aircore holes for 3,961m at West Arunta, with 26WAAC0030 returning 5m at 894ppm Cu at Gibson West.
WCN confirmed copper over 4.75km at Danvers, including 23m @ 6.18% Cu in DAN26036.
WCN issued 515,791,601 shares at $0.017 to Hancock Prospecting for A$8.77 million, about 13.5% of the company.

Strategic Energy Resources Limited (ASX:SER), Tali Resources Ltd (ASX:TR2) and White Cliff Minerals Limited (ASX:WCN) each released copper-focused exploration updates on 28 October 2026. SER started diamond drilling at its Diamantina Project in Queensland, Tali reported aircore assays from the West Arunta Project in Western Australia, and White Cliff reported its September quarter at the Rae Copper Project, where drilling extended the Danvers system.

SER Starts Diamond Drilling at Elizabeth Springs East

SER has begun a two-hole diamond program of about 1,500m at the Elizabeth Springs East Prospect within the 100%-owned Diamantina Copper-Gold Project, 280km south of Cloncurry. The first hole, about 800m long, will be drilled beneath DCT010, which returned 6.5m @ 0.52% Cu and 0.16% Ni from 423m, and is partly funded by a $275,000 Queensland Government grant. The second hole steps out from DTD002, which recorded 161m @ 0.4% Cu and 0.11g/t Au from 449m, including 17.3m @ 1.76% Cu and 0.37g/t Au from 465.3m.

Historical drilling covers only an 800m x 800m area within a 4km x 2km coincident magnetic and gravity anomaly. The program completes SER's 2026 field season after diamond drilling at Canobie and Bulimba. The Diamantina licences, EPM27134 and EPM27135 plus four applications, cover more than 1,800km2 of the projected undercover extension of the Mt Isa Eastern Fold Belt, and SER acquired the project from Anglo American in July 2025. DTD006b, 80m from DTD002, intersected 87.3m @ 0.30% Cu and 0.16g/t Au from 489.7m.

Tali Reports Aircore Results from West Arunta

Tali drilled 72 aircore holes for 3,961m between June and August 2026. At Gibson West, hole 26WAAC0030 returned 5m at 894ppm copper from 4m, including 1m at 1,500ppm copper from 8m in sandstone, while a twin hole confirmed the anomalism in sandstone but not the underlying siltstone. At Chilka East, holes extended platinum group element anomalism over about 600m of strike, with palladium of 10-21ppb and platinum of 5-9ppb.

At Hutt, hole 26WAAC0063 returned 8m at 0.4 g/t Ag, 917ppm Pb and 1,080ppm Zn. The Caspian East and Lonar East gravity anomalies were explained by basalts and mafic intrusives, with no local signs of mineralisation. Aircore drilling has recommenced at the project. Composite 4m samples were assayed by ALS Perth, and the holes targeted geophysical anomalies near the Central Australian Suture.

White Cliff Extends Danvers and Adds Hancock

White Cliff confirmed copper mineralisation over 4.75km of the Teshierpi structural corridor at Danvers, a 480% expansion on the roughly 820m tested in 2025. DAN26026 returned 50.9m @ 2.81% Cu and 7.66g/t Ag from 39.7m, and DAN26036 returned 23m @ 6.18% Cu and 13g/t Ag from 161m. After quarter end, DAN26047 returned 76.5m @ 2.01% Cu from 49.5m.

First drilling at Bornite Hills intersected more than 32m of bornite-dominant mineralisation, with maiden assays of 15.0m @ 1.62% Cu and 11.5m @ 2.00% Cu. Cash was A$1.32 million at 30 September. Hancock Prospecting subscribed A$8.77 million for 515,791,601 shares at $0.017, approved on 19 October and issued on 22 October. At Hulk, three diamond holes intersected visible chalcopyrite at the Rae Group and Husky Creek Formation boundary, and the known sediment-hosted copper footprint now exceeds 10km2.

What the Three Releases Have in Common

All three companies reported physical drilling data on 28 October 2026. SER's results are historical intercepts that frame a newly started program, Tali's are shallow aircore assays from five prospects, and White Cliff's are diamond and reverse circulation intercepts across several Rae Project targets. Hole counts, depths and funding sources differ, but each release ties its figures to named holes and measured intervals.

FAQs

Q: What is SER drilling at Diamantina?

A: SER is drilling two diamond holes totalling about 1,500m at Elizabeth Springs East, one beneath DCT010 and one stepping out from DTD002.
