Small caps delivered a busy session dominated by financing news and strategic milestones rather than tape-driven noise. Solvonis Therapeutics pulled in fresh institutional capital to fund its central nervous system drug pipeline, Tungsten West secured a landmark £71 million commitment from the UK Government's National Wealth Fund to restart Hemerdon, and Volex told shareholders its new financial year is already running ahead of expectations. Resource explorers were also active, with Eco Atlantic's Falklands partner upgrading target estimates and Galileo Resources unearthing a new porphyry system in Nevada.
Solvonis raises £1.3 million to fund pipeline milestones
Solvonis Therapeutics (LSE:SVNS) has conditionally raised gross proceeds of £1.3 million through a placing of 1.08 billion new shares at £0.0012 each, a discount of roughly 14% to the prior closing price. The London-listed developer of small-molecule therapeutics for central nervous system disorders drew in new institutional backers alongside existing shareholders, with the placing also installing Turner Pope as its new corporate broker. Shares fell 11.14% to 0.1244p on the day, reflecting the dilutive impact of the discounted raise even as the company secured near-term funding.
Net proceeds, combined with existing resources, will fund three priority programmes: assessing the addition of European Union sites to the ongoing SVN-001 Phase 3 study in severe alcohol use disorder, advancing SVN-002 toward a US Investigational New Drug submission and Phase 2b readiness following positive pharmacokinetic bridging data reported in June, and supporting programme-management work on SVN-015 as it advances through the US National Institute on Drug Abuse's Addiction Treatment Discovery Program.
"This fundraising supports clear next steps across our three priority programmes," said Anthony Tennyson, Chief Executive.
The raise buys Solvonis time to hit three distinct clinical inflection points, but the 14% discount underscores the persistent funding gap facing pre-revenue biotechs. With no revenue base and continued dependence on external capital, each milestone, particularly the SVN-002 IND submission and the SVN-001 EU expansion, now carries added weight as the next test of investor confidence before further dilution becomes necessary.
Eco Atlantic's Falklands and South Africa targets upgraded as Navitas reviews resource potential
Eco (Atlantic) Oil & Gas (AIM:ECO) said strategic partner Navitas Petroleum has released new resource estimates for licences in the Falkland Islands and South Africa, with shares edging up 0.66% to 65.14p. Navitas' quarterly report, published on 24 August, put the first drilling target on PL001 in the North Falkland Basin at 640 million barrels of oil on a 2U prospective resource basis, of which Eco's share would be approximately 225 million barrels in a drilling success case once its acquisition of JHI Associates completes.
Navitas plans a multi-target exploration well on PL001, contingent on completing its own licence acquisition, with the Sea Lion Project development campaign due to start in 2027; a success case could see the target tied back to the existing Sea Lion platform. Navitas also flagged additional prospects on PL001 not yet reflected in resource reports, and in South Africa the Block 1 CBK licence saw its own resource review advance.
The upgraded estimates reinforce the rationale behind Eco's decision to increase its exposure to PL001, giving the explorer a larger indirect stake in a basin with an established development pathway via Sea Lion. "The resource estimate released by Navitas for the first drilling target on PL001 further underline the quality and potential of the asset and reinforce our decision to increase Eco's exposure to the licence," said Gil Holzman, President.
UK Government backs Tungsten West with £71 million Hemerdon investment
Tungsten West (AIM:TUN) has agreed terms with the National Wealth Fund, a wholly owned UK Government entity, for a proposed investment of up to £71 million to complete funding for restarting production at its Hemerdon tungsten and tin mine in Devon. Shares jumped 15.57% to 49.81p as the miner works to bring Hemerdon back to full production, having already produced tungsten and tin concentrate last month with final completion testing underway ahead of a targeted production start in the third quarter.
The package splits into a £36.0 million equity investment through 100 million new shares priced at 36p each, a 7.5% discount to the 20-day volume-weighted average price, giving the NWF approximately 7.42% of the enlarged share capital, alongside a debt facility of up to £25 million plus a non-committed £10 million accordion. Proceeds will fund the restart and repay the short-term loan facility announced on 21 May, while the UK Government has also secured a window to negotiate an offtake agreement.
The backing marks a rare direct state investment into a UK critical minerals project and materially de-risks Tungsten West's path back to production. "Hemerdon is a world-class, low-cost and long-life tungsten and tin resource in the UK," said Jeff Court, Chief Executive, with government officials framing the deal as part of a wider Critical Minerals Strategy to strengthen domestic supply chains.
Volex says FY2027 profit set to beat forecasts
Volex (AIM:VLX) told shareholders ahead of its annual general meeting that trading has started strongly in the new financial year, with the Board now expecting full-year underlying operating profit to come in ahead of market expectations. Shares surged 19.48% to 638.0p on the update. The specialist manufacturer of power and data transmission products reported constant currency organic revenue growth of 28.0% year on year for the four months to 31 July, broad-based across all five end-markets.
Growth was led by Complex Industrial Technology, where data centre customer demand held at the elevated exit rate seen in the 2026 financial year, alongside stronger demand for EV and electrification products; Consumer Electricals, Off-Highway and Medical also contributed. Volex cautioned that the 28% figure is flattered by a weak prior-year comparator as new data centre programmes ramped up, pointing instead to sequential trends: average monthly revenue in the period ran 8% above the second-half FY2026 monthly average.
The upgrade signals that Volex's data centre exposure is proving more durable than a one-off comparator effect, giving the market fresh confidence in the diversification strategy across five end-markets. The near-20% share price reaction suggests investors had been pricing in a more cautious outlook before today's confirmation.
Sunrise Resources targets Carlin-type gold at Nevada's Newark project
Sunrise Resources (AIM:SRES) is seeking a joint venture partner to drill deeper at its Newark gold project in Nevada, after historical drill holes ended within mineralisation rather than passing through it. Shares rose 10.0% to 0.022p as the company positions the asset as a Carlin-type gold target warranting further investment.
The company's strategy of bringing in a partner rather than self-funding deeper drilling reflects the capital-intensive nature of proving out a Carlin-style system, where mineralisation often extends well beyond initial hole depths. Success in attracting a partner would validate the target without diluting Sunrise's own balance sheet.
Alt Resources secures gold stream deal, drops Tartana JV
Alt Resources (AIM:ALTR) has signed binding options for a gold stream and a 50% equity stake in a North Queensland gold mine, marking a pivot into a producing or near-producing asset. Shares held at 6.5p as the company confirmed that talks with Tartana Resources over copper sulphate operations have ended without agreement.
The gold stream structure gives Alt Resources exposure to production economics without the full capital burden of outright ownership, while the collapse of the Tartana discussions removes a previously flagged diversification route. The new deal narrows the company's focus toward gold in Queensland at a time when the metal's price backdrop remains supportive for junior miners seeking financing.
Pennant lands second Siemens-driven Auxilium defence sale
Pennant International (AIM:PEN) has secured a further Auxilium software sale through its partnership with Siemens, pushing annual recurring revenue to a record £2.9 million. Shares rose 5.86% to 30.7p on the news.
The repeat sale through the Siemens channel signals the partnership is generating recurring, not one-off, business for Pennant's defence training and support software, strengthening the visibility of its revenue base heading into future periods.
Innovative Eyewear lands 150-store US retail rollout
Innovative Eyewear, a portfolio company of Tekcapital (AIM:TEK), will begin selling its Lucyd Armor smart safety glasses through more than 150 stores of a major US big box retailer from October. Tekcapital shares rose 1.45% to 3.5p.
The rollout marks a significant expansion in physical retail distribution for the smart eyewear line, giving the Tekcapital-backed venture a mainstream US shelf presence ahead of the holiday shopping season.
Tialis formalises advisory pact with AI Auxesis JV
Tialis Essential IT (AIM:TIA) has signed a 12-month strategic advisory agreement with joint venture partner AI Auxesis, carrying a £192,000 annual fee and a 10% disposal incentive subject to independent board sign-off. Shares slipped 2.5% to 46.8p.
The agreement formalises Tialis's ongoing role in the joint venture, giving it a fixed fee income stream alongside a disposal incentive that aligns its interests with a future exit event for the AI Auxesis venture.
Galileo finds new porphyry system in Nevada
Galileo Resources (AIM:GLR) reported that surface analysis has revealed a multistage copper porphyry system at its Nevada project, strengthening the case for an upcoming drilling campaign. Shares jumped 28.0% to 0.8p on the discovery.
The multistage nature of the porphyry system suggests a more complex and potentially larger mineralised footprint than initially mapped, giving Galileo additional justification for the scale of drilling it is now planning to test the target.
Windar Photonics launches retail offer to raise up to £200,000
Windar Photonics (AIM:WPHO) has opened a retail share offer alongside a wider fundraising, with each new share carrying a warrant exercisable at 10p. Shares traded at 26.5p.
The warrant sweetener gives retail participants upside exposure beyond the initial subscription, a structure typically used by small caps to broaden their shareholder base while raising incremental working capital.
BSF Enterprise converts loan notes to equity
BSF Enterprise (AIM:BSFA) has converted part of its convertible loan note into new shares, chipping away at the biotech's outstanding debt. Shares fell 6.32% to 1.171p.
The conversion reduces near-term repayment pressure but adds to the share count, a trade-off common among cash-constrained small caps managing legacy debt facilities.
Synergia lifts Cambay gas output on new well tie-ins
Synergia Energy (AIM:SYN) has boosted gas production at its Cambay licence in India after completing a pipeline tie-in for three legacy wells, with further gains expected within days. Shares dipped 2.61% to 0.0112p.
Bringing previously stranded legacy wells back onto the pipeline network extends the productive life of the Cambay licence at minimal incremental capital cost, with management flagging additional output gains still to come.
Gulf Keystone restarts output, declares $10 million dividend
Gulf Keystone Petroleum returned to production after a security-driven shutdown and declared a semi-annual dividend of $10 million, cut from prior levels, as it pushes for full PSC entitlement on export sales.
The reduced payout reflects the operational disruption from the shutdown, though the resumption of production and continued dividend commitment signal management's confidence in the underlying Kurdistan asset base once entitlement issues are resolved.
Nuformix names Tim Metcalfe as new Chairman
Nuformix (AIM:NFX) confirmed a boardroom handover, naming Tim Metcalfe as new Chairman as it pushes forward with partnering talks on its lead fibrosis programme. Shares rose 1.09% to 0.1668p.
The leadership change comes at a pivotal moment for the pharmaceutical developer, with the incoming chairman set to oversee ongoing partnering discussions that could determine the commercial trajectory of its fibrosis asset.
Eco Buildings appoints two directors, Shala departs board
Eco Buildings Group has named Graham Stevens as independent Non-Executive Director and Chris Gilbert as Executive Director, as Ahmet Shala steps down after more than three years on the board. Shares ticked up 1.38% to 11.0p.

Talon Resources readies maiden drill at Eagle Lake
Talon Resources has completed site preparation for an expanded 1,375 million drilling programme at its Eagle Lake gold project in Ontario, with rig mobilisation due within two weeks. Shares gained 2.98% to 1.313p.
The expanded programme size gives Talon a broader initial test of the Eagle Lake system, with the maiden drill results set to be the key near-term catalyst for the stock.
Savannah Energy brings Uquo 13 gas well on stream in Nigeria
Savannah Energy reported first gas from its Uquo 13 well and a 29% rise in Stubb Creek oil output, alongside a 13% increase in cash collections for the seven months to 31 July. Shares nonetheless fell 9.67% to 5.51p.
The operational gains at both Uquo and Stubb Creek point to underlying production momentum, even as the share price move suggests investors are focused elsewhere, possibly on cash collection timing or broader Nigerian country risk.
Southern Energy sales rise 4% despite field shut-ins
Southern Energy lifted second-quarter sales by 4% on stronger oil prices, even as a transportation dispute kept two fields offline. Shares traded at 3.75p.
The sales growth despite the field shut-ins underscores the resilience of the Gulf Coast-focused producer's pricing realisations, though resolution of the transportation dispute remains the key swing factor for near-term volumes.
Emmerson gets Morocco arbitration hearing date for July 2028
Emmerson's $1.215 billion treaty claim against Morocco will reach a hearing nearly two years from now, after the tribunal set out the remaining procedural calendar. Shares fell 1.76% to 1.67p.
The lengthy timeline underscores how protracted international arbitration proceedings can be, leaving the AIM-listed potash developer's claim against Morocco as a multi-year overhang rather than a near-term catalyst.
80 Mile's Ferrandina plant secures dual sustainability certification
80 Mile's Greenswitch subsidiary has won Italian and EU sustainability accreditation for its Ferrandina biodiesel facility ahead of restart, unlocking access to premium-priced certificate schemes. Shares edged up 0.98% to 0.5372p.
The dual certification gives Ferrandina access to higher-value sustainability certificate markets once the plant resumes operations, improving the economics of the restart relative to selling into uncertified biodiesel channels.
