Key Highlights

  • Sunstone (ASX:STM) reported 126.3 metres at 0.41 g/t AuEq from trench PO-16a at Bramaderos in Ecuador.
  • High-Tech (ASX:HTM) plans up to 7,500 metres of RC drilling at its Damsel deposit in the Northern Goldfields.
  • Dundas (ASX:DUN) reported 16 metres at 0.8 g/t gold from 28 metres at Capricorn near Kalgoorlie.
  • Each company describes its results as guidance for further exploration rather than resource outcomes.

Three ASX-listed gold explorers released updates on 4 November 2026. Sunstone Metals Limited (ASX:STM) reported trenching results at Bramaderos in Ecuador, High-Tech Metals Ltd (ASX:HTM) outlined a drilling plan at Damsel in Western Australia's Northern Goldfields, and Dundas Minerals Limited (ASX:DUN) reported drilling at Capricorn and Rockland near Kalgoorlie.

Sunstone and the Bramaderos Trenches

Broad surface intervals from trench PO-16a returned 126.3 metres at 0.41 g/t AuEq, and PO-10b recorded the highest average grade in the program at 30.4 metres at 0.64 g/t AuEq. Copper-in-soil anomalism now extends south of the resource pit shell, and new reconnaissance trenching is being assessed.

The Bramaderos trenches are surface sampling, and the company uses the intervals to show continuity along strike. The results are being integrated with drilling and geological mapping to refine the interpretation of the Porotillo system.

High-Tech and the Damsel Plan

The Damsel resource holds 75,000 ounces of gold across about 700 metres of strike. High-Tech plans up to 7,500 metres of Reverse Circulation Drilling to test prospects outside that estimate, including a corridor of roughly 12 kilometres that the company has identified.

High-Tech's plan covers a 12-kilometre corridor and a second structure of about 5 kilometres. The company describes both as largely outside the current resource, so the planned drilling is aimed at defining new ground rather than upgrading existing estimates.

Dundas and the Capricorn Results

Hole 26CRC012 returned 16 metres at 0.8 g/t gold from 28 metres, and Rockland hole 26RKRC014 returned 12 metres at 1.0 g/t gold. Dundas says seven of the eight recent Rockland holes have intersected gold, and that further assays from Capricorn and the Baden Powell resource are still awaited.

Dundas's Capricorn results sit within the existing drilling, which the company describes as shallow extensional gold. The Rockland rig is scheduled to return in about 10 days for resource definition and extensional work.

Points Common to the Three Updates

Each company links its results to further exploration, whether through new trenches, planned drilling or assays that remain outstanding. None of the updates includes a new resource estimate, and each one notes that the data reflects surface, composite or early drilling intervals.

Across the three updates, each company presents early exploration data with stated limits. The grades and intervals help guide the next phase of work, but none of the announcements establishes a resource or production capacity.

Final Word

The three updates show gold mineralisation being tested through trenching, drilling and sampling across different jurisdictions. The reported intervals are informative about where work is directed, but none of them establishes a resource upgrade. Timing of future assays, drilling and resource work will determine how these early results develop. The three companies report on different project scales and stages, from a large gold-equivalent resource in Ecuador to Western Australian programs that are still producing initial intervals. Their reporting bases differ, so the figures are best read within each company's own disclosure.
