Mining equities delivered a mixed session as operational setbacks in West Africa contrasted with strength further downstream. Resolute Mining's guidance cut on its Mali operations dominated the news flow, while Iofina's blowout half-year results and a raft of smaller exploration and corporate updates from Blencowe Resources, Mkango Resources, Guardian Metal Resources, Hamak Gold and Anglesey Mining rounded out a busy day for the sector.
Resolute Mining slashes Syama guidance on Mali disruptions
Resolute Mining (LSE:RSG), the West Africa-focused gold miner, has cut its 2026 production guidance for the Syama Gold Mine in Mali to between 150,000 and 160,000 ounces, down sharply from prior expectations, sending the shares down 6.48% to 66.4p. The downgrade follows months of disruption to underground mining, open pit operations and sulphide processing that has persisted since the second quarter, rooted in what the company describes as Mali's challenging operating environment.
The scale of the shortfall is stark: July and August output totalled just 15.5koz, well below plan, after explosive supply shortages during the wet season forced Resolute to substitute ANFO and delayed access to higher-grade ore at the A21 open pit. All-in sustaining costs at Syama are now expected to reach $2,300 to $2,400 an ounce against a $4,000 gold price assumption, while group-wide 2026 production guidance has been cut to 205,000-225,000 ounces at an AISC of $2,250-$2,350 an ounce. Resolute has switched open pit mining contractors and is building an onsite emulsion plant, targeted for commissioning in November, with September output tracking near 15koz, third-quarter output near 31koz, and a fourth-quarter recovery envisaged at 45,000 to 50,000 ounces.
"While the near-term impact at Syama is disappointing, the broader business remains supported by a strong gold price environment and disciplined cost management," said Chris Eger, chief executive of Resolute Mining.
The episode underscores the operational risk premium that continues to shadow Mali-exposed gold producers, even as bullion prices sit near record highs. With Mako in Senegal on track for 55,000-65,000 ounces and Doropo in Côte d'Ivoire progressing on schedule and budget toward first concrete next month, Resolute's diversification is cushioning the blow, but the repeated nature of Syama's disruptions, now stretching across three quarters, raises the question of how durable the company's cost discipline claims are if Mali's logistics environment does not stabilise.
Blencowe names interim CEO as Orom-Cross funding talks continue
Blencowe Resources (LSE:BRES), the AIM-listed graphite developer focused on its wholly owned Orom-Cross project in Uganda, has appointed Iain Wearing as interim chief executive with immediate effect, a move that lifted the shares 7.39% to 6.25p. Wearing, previously chief operating officer, led the technical work behind the project's Definitive Feasibility Study and will now oversee funding, technical and operational workstreams while the board searches for a permanent CEO; he has personally invested around £500,000 in the company through previous capital raisings and does not join the board in his interim role.
The updated feasibility model puts Phase 1 capital expenditure at $45m, with Blencowe weighing strategic, institutional and development-finance funding routes. The US International Development Finance Corporation has already backed the feasibility study through a technical assistance grant, and discussions with development finance institutions are running alongside commercial talks, following a recent £3m raise.
"Our priority is to convert that progress into Phase 1 funding and binding commercial agreements. Multiple discussions and due diligence processes are active, and we are pursuing a funding structure that supports development and delivers value for shareholders," said Wearing. Installing an internal technical leader as caretaker chief executive signals continuity of strategy through the funding push, but the company's ability to close a $45m financing package will be the real test of whether Orom-Cross moves from feasibility to construction.
Mkango Resources to rename itself Mkango Magnetic Materials
Mkango Resources (AIM:MKA), dual-listed on AIM and the TSX Venture Exchange, is changing its name to Mkango Magnetic Materials, with shares down 4.44% to 43.0p on the day. The rebrand, taking effect at the start of trading on 23 September, reflects the company's transition from a primary rare earth project developer to a business now centred on downstream magnet manufacturing and recycling; the ticker MKA and website remain unchanged, though new CUSIP, ISIN and SEDOL identifiers accompany the switch.
The downstream push runs through Maginito, 79.4% owned by Mkango and 20.6% by CoTec Holdings, which controls HyProMag's UK short loop magnet recycling operation, a 90% interest in HyProMag Germany, and Mkango Rare Earths UK's long loop chemical recycling business. A German subsidiary's Remloy operation adds medium loop recycling capacity in Bitterfeld, producing neodymium-iron-boron alloy powders.
The name change formalises a strategic pivot that has been under way for some time, positioning the company squarely within the magnet supply chain rather than as a rare earth exploration play, a repositioning aimed at aligning investor perception with where the group's commercial activity, and its funding relationship with CoTec, actually sits.
Guardian Metal fast-tracks Tempiute mine access after strong tungsten hits
Guardian Metal Resources (LSE:GMTL) will begin rehabilitating historical underground workings at its Tempiute tungsten project in Nevada, after drilling returned a 92-metre intersection grading 0.34% tungsten trioxide. Shares rose 2.47% to 166.0p on the update.
The decision to fast-track access to the old workings follows what the company regards as a strong result from recent drilling, and positions Guardian Metal to accelerate its understanding of the historical mine ahead of further resource work at the Nevada project.
Hamak Strategy sells 8 Bitcoin to fund Akoko gold study
Hamak Gold (LSE:HAMA), the dual-strategy miner, sold 8 Bitcoin from its treasury after a rise in the cryptocurrency's price, with shares up 2.22% to 0.69p. Proceeds will be directed toward funding work on its Akoko gold project in Ghana and toward reducing debt.
The disposal shows the company actively managing its Bitcoin holding as a funding source for its core mining ambitions rather than as a passive treasury asset, using a favourable price window to support both project advancement and balance sheet repair.
Anglesey Mining identifies four targets at Parys Mountain
Anglesey Mining (LSE:AYM), trading at 7.0p, has had satellite and geological analysis conducted by Satellite Applications Catapult and the British Geological Survey flag four areas warranting further exploration at its Parys Mountain polymetallic project in Wales.
The identification of new target areas gives Anglesey a fresh set of leads to prioritise ahead of further ground-based exploration at the historic Welsh site, adding to the project's existing resource base.
