A day of corporate repositioning and exploration progress across the small-cap mining sector, with deadline extensions, resource boundary breakthroughs, and a full strategic pivot to uranium all competing for attention. Vast Resources (AIM:VAST)'s one-month extension on its Gulf International Minerals reverse takeover was the headline event, while Strategic Minerals delivered the most operationally significant news with tin and tungsten hits beyond Redmoor's known resource boundary.
Vast Resources extends Gulf International Minerals acquisition deadline to end of July
Vast Resources (AIM:VAST) pushed back the long-stop date on its proposed reverse takeover of Gulf International Minerals by one month to 31 July, buying additional time to complete the transaction. The shares responded positively, adding 4.35% to trade at 0.12p.
Strategic Minerals finds tin and tungsten beyond Redmoor resource boundary
Strategic Minerals (AIM:SML) reported that additional assay work on 2025 drill core has returned mineralised intersections north of Redmoor's modelled resource boundary, extending the known footprint of the deposit. A second active drillhole was advancing toward target depth at the time of the announcement, pointing to further results ahead.
The news represents a meaningful step for the Redmoor project, suggesting the resource could be larger than currently modelled. Despite the positive exploration update, the shares slipped 7.66% to 4.1p on the day.
Tertiary Minerals outlines JORC target at Mushima North as cash nears critical low
Tertiary Minerals (AIM:TYM) published a JORC exploration target of 15 to 30 million tonnes at its Mushima North silver-copper project in Zambia, providing a formal framework for the planned drilling restart. The target adds technical credibility to the project at a moment when the company's financial position is under pressure, with its cash balance having fallen to just £78,000.
The near-critical cash position means funding will need to be secured before drilling can meaningfully advance. The shares edged up 4.76% to 0.055p, reflecting cautious optimism around the exploration target.
Arkle Resources repositions entirely around Namibian uranium licences
Arkle Resources CDi (AIM:ARK) closed 2025 with a £2 million operating loss but has since completed a full strategic pivot, repositioning the company around uranium licences in Namibia's Erongo Region following its acquisition there. The move marks a clean break from the company's prior exploration focus and aligns it with one of Africa's most established uranium-producing belts.
The repositioning was met with selling pressure on the day, with the shares falling 9.68% to 0.7p.
