Financing and drilling news dominated the mining sector today, with copper development at the centre of the biggest story as Unicorn Mineral Resources drew down a chairman-backed loan to advance its Namibian acquisition. Explorers across the AIM board reported drilling progress, from Botswana's Kalahari Copper Belt to Zambia's Mushima North, while Anglesey Mining posted a maiden profit after a debt-clearing restructuring and ACG Metals saw its flagship Turkish asset revalued sharply higher.
Unicorn draws down £1.25m chairman loan for Klein Aub copper deal
Unicorn Mineral Resources (LSE:UMR) has completed full drawdown of a £1.25m unsecured loan facility from Electro Automation (Group), a company controlled by its chairman Paddy Doherty, as the miner pushes ahead with its acquisition of the Klein Aub Copper Mine in Namibia. Shares in Unicorn edged up to 8.25p, a gain of 3.125%, as the market digested confirmation that the facility first flagged on 17 August is now fully in place. The funding underscores a strategic pivot: Unicorn is moving from pure exploration towards becoming an operating copper producer in Southern Africa.
Proceeds will cover completion of the Klein Aub acquisition, initial site development and preparatory works, the establishment of an operational presence in Namibia, and technical and metallurgical studies, alongside general working capital needs across the company's Namibian and Irish operations. The facility carries no security over Unicorn's assets, a 10% annual interest rate and a maturity one year from first drawdown. It follows the recent signing of formal acquisition documentation for the historical mine, which comprises old workings, mineralised material and tailings that Unicorn intends to evaluate for redevelopment.
"We are increasingly focused on transitioning Unicorn towards becoming an operating mining company, and Klein Aub represents a significant opportunity to establish a substantial revenue producing copper project in Namibia," said John O'Connor, chief financial officer of Unicorn Mineral Resources.
The related-party structure of the loan, funded personally by the chairman's own company rather than external lenders, signals continued insider confidence but also concentrates financial exposure to Klein Aub within a tight circle of backers. With acquisition paperwork now signed and capital drawn, Klein Aub has moved from an announced ambition to a funded, active development programme, putting pressure on Unicorn to demonstrate technical and metallurgical viability before the loan matures in a year's time.
Sunrise Resources secures fundraise for new drilling
Sunrise Resources (AIM:SRES) has conditionally raised £320,000 before expenses through a placing of 2.13bn new shares at 0.015p each, emerging from a Capital Access Window trading halt that began on 9 September. Shares resumed trading at 7:30am on 17 September and fell to 0.0165p, down 17.5%, as the placing price sat below the pre-halt level. Each placing share comes with a warrant exercisable at 0.0175p within 12 months, with Sunrise able to force early exercise if the stock closes above 0.0225p for five consecutive sessions.
Executive chairman Patrick Cheetham subscribed £15,000 for 100m shares, while non-executive director Adam Hainsworth committed £20,000 for 133.33m shares, both signalling insider support for the raise. Broker AlbR Capital, which arranged the placing, will take 106.67m warrants at the placing price as part of its engagement terms.
Net proceeds will fund general working capital and preparatory work for drill testing across Sunrise's gold and base metal projects in Nevada and Australia, including geophysical groundwork ahead of planned campaigns. The dilutive scale of the raise relative to the company's existing share count explains the sharp share price reaction, even as the cash injection gives Sunrise the runway to advance drill-ready targets on two continents.
Serval completes geophysics surveys at Kalahari copper prospects
Serval Resources (AIM:SRVL) has completed geophysical surveys at its Somelo prospect in Botswana's Kalahari Copper Belt, with similar work nearing completion at the neighbouring Sweet Thorn Pan prospect. Shares fell to 30.0p, down 14.286%, even as the explorer advanced a program aimed at building an independent copper and future-metals business along strike from MMG's Khoemacau mine, which holds a resource of 450m tonnes at 1.4% copper and 18 grammes per tonne silver.
At Somelo, the work combined audio-frequency magnetotellurics, induced polarisation and high-resolution drone magnetic surveys across 51, 4.45 and 170 line-kilometres respectively, targeting the mineralised contact between the Ngwako Pan and D'kar Formations beneath Kalahari sand cover. At Sweet Thorn Pan, a project previously drilled under prior ownership, a 630 line-kilometre drone magnetic survey at 50-metre line spacing is under way, concentrating on anticlinal structures and historically identified targets.
"We will now focus on processing and interpreting the new data... and defining the most compelling targets for follow-up exploration, including drilling, subject to receipt of additional funding in due course," said Robin Birchall, chief executive of Serval Resources. The funding caveat is notable: Serval has generated a fresh target pipeline but still needs fresh capital to convert that data into drill results, leaving the next catalyst contingent on a financing decision rather than geology alone.
Tertiary Minerals hits record-grade silver-copper intersection at Mushima North
Tertiary Minerals (LSE:TYM) reported its highest-grade silver-copper intersection to date at the Discovery Zone within its Mushima North Project in Zambia, sending shares up 3.571% to 0.0725p. Drill hole 26TMNRC-066 returned 82 metres at 107 grammes per tonne silver equivalent from just 8 metres downhole, a result that ended in mineralisation rather than closing it off. The Discovery Zone sits within Target A1, where Tertiary has already outlined a near-surface exploration target of 15 to 30m tonnes at 40 to 60 grammes per tonne silver equivalent.
The latest results, from four further holes drilled under the Phase 4 programme, follow analytical updates issued on 1, 7 and 15 September. Two of the four holes ended in mineralisation, extending known depth beyond the current exploration target boundary and indicating the system remains open. The batch also delivered the highest individual silver assay recorded on the project to date, at 659 grammes per tonne.
"These results released today, along with the results over the last few weeks, are incredibly compelling for the potential to expand the current known extent of mineralisation at the Discovery Zone," said Richard Belcher, managing director of Tertiary Minerals. With mineralisation still open at depth and further laboratory results pending, the project's resource footprint looks set to grow beyond current boundaries, strengthening the case for an upgraded exploration target once assays for the remaining holes are in hand.
ACG Metals lifts Gediktepe valuation to $1.2bn
ACG Metals (ACG) has published an updated technical report valuing its Gediktepe copper-gold mine in Turkey at approximately $1.2bn, a near-fivefold increase from the $265m valuation two years ago. Shares eased to 1900.0p, down 3.797%, despite the sharply higher figure, suggesting the market had already priced in much of the asset's re-rating potential.
The scale of the upward revision points to substantial resource growth or improved economics at Gediktepe since the earlier assessment, reinforcing the mine's status as ACG's flagship producing asset. The disconnect between the bullish valuation and the day's share price move leaves room for the market to catch up once further operational detail underpins the headline number.
Anglesey Mining swings to profit after debt wipeout
Anglesey Mining (AYM) posted a £2.08m profit for the year to March 2026, a turnaround driven by a balance sheet restructuring that eliminated its debt entirely. Shares held at 7.0p as the developer refocused the business squarely on its sole mineral asset, the Parys Mountain project in Wales.
Clearing the debt overhang removes a long-standing constraint on Anglesey's ability to fund development at Parys Mountain, and the maiden profit gives the company a cleaner financial footing from which to pursue the project without the drag of legacy liabilities weighing on future capital-raising efforts.
Strategic Minerals passes milestone in Redmoor drill programme
Strategic Minerals (SML) said its joint venture Cornwall Resources has completed nine drillholes at the Redmoor tin-tungsten project on time and on budget, with shares rising 5.319% to 4.95p. The milestone comes as tungsten prices trade well above the upside case used in Redmoor's March economic study, improving the project's implied economics without any change to the underlying resource.
Delivering the drilling phase on schedule and within budget strengthens confidence in Cornwall Resources' execution, while the tungsten price backdrop gives Strategic Minerals a stronger platform from which to argue for an updated, more favourable economic assessment of Redmoor in due course.
Tees Valley Lithium secures £18.3m UK grant offer
Tees Valley Lithium, the refinery subsidiary of Alkemy Capital Investments (ALK), has received an Offer in Principle for £18.3m of non-dilutive government funding under the DRIVE35 automotive transformation programme. Alkemy shares climbed 4.17% to 250.0p on the news.
Non-dilutive grant funding at this scale reduces the equity capital Alkemy would otherwise need to raise to bring the lithium refinery to production, easing dilution pressure on existing shareholders while signalling government backing for the UK's domestic battery-materials supply chain.
GreenRoc's graphite project shows low-carbon footprint in initial study
Greenroc Strategic Materials (GROC) said an independent assessment places its planned Amitsoq graphite anode material at the lower end of industry benchmarks for carbon emissions. Shares slipped 3.1% to 4.1668p despite the favourable environmental positioning.
A low-carbon profile could prove commercially valuable as battery makers and their automotive customers face tightening scrutiny of supply-chain emissions, giving GreenRoc a potential marketing edge with Amitsoq graphite as it seeks offtake and financing partners.
Savannah nears completion of Barroso field programme
Savannah Resources (SAV) has largely completed geotechnical and hydrogeological drilling at its Barroso lithium project in Portugal, with the final phase of work due within weeks. Shares rose 1.79% to 5.955p as the company progressed toward wrapping up this stage of site investigation.
Completing the geotechnical and hydrogeological work clears a key technical dependency ahead of further permitting and engineering milestones at Barroso, keeping Savannah on track as one of Europe's more advanced lithium hard-rock development projects.
