Energy names dominated the small-cap news flow, with Tullow Oil's upgraded cash flow guidance setting a bullish tone against a starkly contrasting warning from Ferrexpo over its Ukrainian operations. Elsewhere, gold and rare earth explorers delivered a run of exploration progress updates, from ECR Minerals' underground development at Maddens to New Frontier's new copper-nickel target at Harts Range, while Air Astana's swing to a first-half loss underscored the pressure rising costs are putting on carriers even as revenue climbs.
Tullow Oil lifts free cash flow guidance on strong first-half output
Tullow Oil (LSE:TLW), the Ghana-focused independent oil and gas producer, upgraded its full-year free cash flow guidance to $170-250 million, up sharply from a previous range of $70-175 million, ahead of half-year results due 28 September. The shares eased 1.99% to 15.0157p even as the update pointed to stronger operational momentum, with the upgrade reflecting higher production, oil price realisations of around $93 a barrel between January and end-July, and progress recovering long-outstanding receivables owed by the Government of Ghana.
Group production averaged approximately 43.7 thousand barrels of oil equivalent per day in the first half, with gross output from Jubilee and TEN running above expectations at 70.8 and 14.8 thousand barrels of oil per day respectively. First-half sales revenue reached around $496 million, including $47 million in hedge costs, though free cash flow of just $4 million was dented by $68 million of one-off refinancing costs. Net debt stood at $1.4 billion at 30 June, with liquidity headroom exceeding $250 million, while full-year production is now expected at the high end of the 34-42 kboepd range, with 14 cargo liftings planned versus the original guidance of 12.
"We have delivered a strong operational performance in the first half of 2026, driven by our new wells performing ahead of expectations, production optimisation activities delivering tangible benefits and consistently high uptime across our assets," said Ian Perks, chief executive of Tullow Oil.
The scale of the guidance revision, lifting the midpoint by around $87.5 million, signals that Tullow's deleveraging story is gaining real traction rather than merely tracking oil prices higher. With a final well from the current campaign due onstream in September and receivables recovery from Accra now bearing fruit, the update strengthens the case that free cash flow generation, not just production growth, is becoming the dominant driver of the equity story, even if the one-off refinancing charge is a reminder that balance sheet repair remains a work in progress.
Air Astana swings to first-half loss as costs outpace revenue growth
Air Astana JSC (LSE:AIRA), the Kazakhstan-based airline group that also operates budget carrier FlyArystan, reported second-quarter revenue and other income up 18.3% to $433.0 million, against $365.8 million a year earlier, even as capacity stayed broadly flat and the group shifted flying towards higher-margin international routes. Shares traded at 5.8p. Unit costs outran unit revenue over the quarter, however, pushing EBITDAR down 3.7% to $93.6 million and the margin down 4.9 percentage points to 21.6%, tipping the group to a second-quarter net loss of $0.1 million against an $18.0 million profit a year earlier.
The first-half picture was starker: revenue rose 16.1% to $763.9 million, but the group swung to a net loss of $21.2 million from a $10.7 million profit in H1 2025, as EBITDAR fell 9.7% to $141.7 million. Cost pressure came from a near-doubling of average fuel prices at international stations year-on-year and a stronger tenge. "Our visibility on P&W has improved significantly; we currently have around 60% fewer groundings than the equivalent period last year and anticipate zero groundings in summer 2027," said Ibrahim Canliel, chief executive.
The improving outlook on Pratt & Whitney engine groundings offers a credible path back to profitability, but the scale of the swing from an $10.7 million first-half profit to a $21.2 million loss shows how exposed Air Astana remains to fuel costs and currency moves in the near term, regardless of underlying demand strength.
ECR Minerals nears gold output at Maddens project
ECR Minerals (AIM:ECR), the AIM-listed Australian gold exploration and development company, said underground development at its Maddens Underground Mine has begun generating ore, now stockpiled on the run-of-mine pad ahead of processing. Shares jumped 13.51% to 0.21p on the update. The company holds a 50% interest in the Maddens Gold Project, part of the historic Maddens Flat Group of Mines in North Queensland, which it has flagged as one of its highest-priority production opportunities.
Development has intersected an additional mineralised quartz vein containing visible gold, distinct from the main Maddens Reef, while the next phase of decline development is expected to start shortly and a Knelson gravity concentrator is due on site within weeks to improve gold recovery. At the Brothers Mining Lease, personnel and equipment redeployed from ECR's Raglan operation in July are being mobilised for trial alluvial mining. "Underground development is generating ore for future processing, preparations for the next phase of decline development are well advanced and upgrades to the processing plant continue," Mike Parker, non-executive director, while chairman Nick Tulloch, added that "our focus is now firmly on execution."
The move from exploration commentary to actual ore generation marks a tangible inflection for ECR, shifting the narrative from resource definition towards near-term cash generation, provided the processing plant upgrades and gravity concentrator installation proceed to schedule.
New Frontier identifies copper-nickel target at Harts Range
New Frontier Minerals (LSE:NFM), the London and Australia-listed explorer focused on heavy rare earths, niobium and tungsten, has identified an untested bedrock conductor within its 100%-owned Harts Range project in the Northern Territory, following independent modelling by Southern Geoscience Consultants. Shares stood at 0.375p. The conductor sits around 240 metres below surface within tenement EL 34147, modelled from Geoscience Australia's publicly available AusAEM airborne electromagnetic data, and extends 679 metres in a north-northwest direction.
Southern Geoscience concluded the target is prospective for copper-nickel mineralisation, and it lies 3.5km south of the Kings Cross magnetic anomaly, where New Frontier already has government approval to drill a discrete target at similar depth. The find also sits within 40km of the C2 conductor identified through BHP Xplor-backed research published by Litchfield Minerals in June, which interpreted deep conductive architecture in the same region. "The results reinforce our view that Harts Range has the potential to host a much broader mineral system than previously recognised," said Gerrard Hall, chairman.
The proximity to both a BHP-linked discovery and New Frontier's own approved drill target suggests Harts Range could evolve into a multi-commodity story beyond its original rare earths thesis, adding a base-metals dimension that may broaden investor interest ahead of drilling.
Angus Energy completes annual maintenance at Saltfleetby field
Angus Energy (ANGS), the AIM-listed gas producer, has restored the Saltfleetby field to full production following a planned shutdown, with shares edging up 2.7% to 0.19p on the update.
Output is now running above pre-maintenance rates, giving the company a clean run into the next reporting period after completing the scheduled works without apparent disruption to the broader production plan.
Ferrexpo halts Ukraine production over Black Sea logistics crisis
Ferrexpo (FXPO), the iron ore pellet producer, has suspended mining and pelletising in Ukraine to preserve working capital as Black Sea export routes remain disrupted, sending shares down 6.84% to 28.58p. The company warned cash could run out by mid-September if the situation is not resolved.
The suspension marks a sharp escalation from the operational disruptions Ferrexpo has navigated since the war began, with the explicit cash-runway warning signalling that logistics constraints, rather than mining capability, are now the binding threat to the business.
Strategic Minerals expands Redmoor drilling to 22,500 million
Strategic Minerals (SML) has expanded its drilling programme at the Redmoor tin-tungsten-copper project to 22,500 metres, with shares slipping 2.78% to 3.597p despite the increased commitment. Executive Director Mark Burnett said the scale of the programme "reflects the opportunity at Redmoor" and the company's push to advance the project through feasibility studies "as expeditiously as possible".
The expanded programme signals management's confidence in the resource base at Redmoor, though the muted share price reaction suggests the market is waiting for assay results and feasibility milestones before re-rating the stock.
Orosur drilling extends Pepas West gold zone
Orosur Mining (OMI) reported drilling results extending the Pepas West gold zone, with shares trading at 14.5p. Chief executive Brad George said "the grade is there which in the end is all that matters," underscoring the company's focus on grade quality over sheer strike extension.
The comment points to a deliberate strategy of prioritising economics over headline resource size, a pragmatic stance for a junior explorer aiming to de-risk the path towards a development decision at Pepas West.
