Three gold explorers on the ASX finished sharply lower on 12 November 2026, with Mount Hope Mining (ASX:MHM) closing at $0.165, down 17.50%, Magmatic Resources (ASX:MAG) closing at $0.017, down 15.00%, and Sentinel Metals (ASX:SNM) closing at $0.27, down 10.00%. The S&P/ASX 200 closed at 9,146.80, lower by about 6.40 points or roughly 0.07%, so the declines were concentrated in the gold explorers rather than the wider market. Each company has released drilling news in recent days.

Mount Hope Mining (ASX:MHM): Phase 3 Gold Drilling at Mt Solitary

Mount Hope reported on 10 November 2026 that its Phase 3 reverse circulation programme at the Mt Solitary prospect in New South Wales had extended high-grade gold down dip. The best intercept was 6 metres at 6.8 grams per tonne gold from 268 metres to the end of hole 26MSRC031, including 4 metres at 9.9 grams per tonne. Gold was also intersected about 280 metres below surface on two drill sections roughly 120 metres apart.

The company said Phase 4 diamond drilling would begin shortly to test the down-dip extension of those holes and to contribute to a maiden mineral resource estimate for Mt Solitary. The project sits within Mount Hope's 100% owned Mt Hope Project.

Magmatic Resources (ASX:MAG): Otto 2 Gold Intercepts at the Weebo Project

Magmatic reported on 9 November 2026 that Reverse Circulation Drilling at Otto 2 returned 5 metres at 7.78 grams per tonne gold from 184 metres, including 2 metres at 18.2 grams per tonne. Gold mineralisation now extends 320 metres along strike and remains open to the north, south and at depth. The recent programme comprised 12 holes for 2,596 metres across Otto 2, Ockerburry 3 and Scone Stone West.

The company plans a wireline logging survey to confirm structural orientations, followed by further reverse circulation or diamond drilling. Magmatic owns 100% of the project, which it says has the potential to add significant value.

Sentinel Metals (ASX:SNM): Columbia Drilling and the Big Springs Acquisition

Sentinel's September 2026 quarterly report, dated 29 October 2026, included maiden diamond drilling at Columbia. Hole DDC026-001 returned 46.8 metres at 5.5 grams per tonne gold from 88.2 metres, including 21.4 metres at 11.1 grams per tonne. Hole DDC026-003 intersected multiple stacked gold zones, including 6.1 metres at 3.50 grams per tonne from 81.0 metres.

The company completed the Acquisition of the Big Springs Gold Project in Nevada, which carries a 1.01 million-ounce gold resource, alongside Columbia's 920,000-ounce resource. An updated Columbia mineral resource estimate is scheduled for November 2026, with assays from remaining holes still pending.

Final Word

The three gold explorers are at different stages, from Mount Hope's Phase 4 drilling to Sentinel's resource update, and each has recent results to test. Their share price moves on 12 November came without new drilling announcements that day, and the coming assays and resource figures will be the next markers for each company.

FAQs
