Yesterday Rockfire Resources plc (ROCK), the base metal, critical mineral and precious metal exploration company, focused on its 100%-owned Molaoi zinc deposit in Greece, held a well presented and received investor lunch in the City of London. The highlights here were the company’s positive funding position, the strategic value of germanium, and prospects for non-dilutive funding particularly from the EU and US.
Rift Helium plc (RIFT), focused on the exploration and development of primary helium in a proven basin in southwest Tanzania, said “It was an honour to open the London Stock Exchange yesterday and for Rift to take part in the market opening ceremony. Our recent admission to AIM is a key step forward for the Company, providing the platform to progress our funded exploration programme at the Upepo Project as we look to apply our third-mover advantage in Tanzania’s proven Rukwa Basin.”
Comment: Given the urgent need for helium, exacerbated by the Iran conflict, one hopes that RIFT will do better, produce it quicker, need to raise less money, and generally out do Helium One’s (HE1) efforts in the Rukwa Basin.
Catenai PLC (CTAI), the AIM quoted provider of digital media and technology services, announces an update relating to Klarian Ltd, a company to which Catenai provided a £450,000 unsecured convertible loan note facility (“CLN”) as per the announcement of 25 April 2024. The Company has entered into a further extension agreement with Klarian. Under the terms of the Extension Agreement, Klarian will repay Catenai £699,160 due under the CLN and related fees as at 1 April 2026, by 1 July 2026 together with an additional fee of 3% per month (or part thereof) which will accrue on the outstanding balance until repayment. There can be no certainty that Klarian will complete the Repayment in full by the Repayment Date, however; Klarian has confirmed it will endeavour to make an initial repayment on or before 1 July 2026.
To present further details and answer questions on Klarian’s latest developments, the company will hold an investor webinar with Andrew Garner, Chairman of Klarian and Gary Chandler, Klarian’s Chief Technology Officer, via the Investor Meet Company platform at 10.00 a.m. on 5 June 2026. Investors can sign up to Investor Meet Company for free and add to meet Catenai plc via: https://www.investormeetcompany.com/catenai-plc/register.
Comment: We look forward to more information on Klarian, especially on the basis that it should be the case that the more people understand the offering, the better it will be for the still relatively modest CTAI share price.
Creo Medical Group plc (CREO), the medical device company focused on the emerging field of minimally invasive surgical endoscopy for pre-cancer and cancer patients, announces its audited final results for the 12 months ended 31 December 2025, which are in-line with market expectations and within prior management guidance. CREO has entered into a non-binding agreement (“LOI”) with a company owned by Luis Collantes, the CEO of Creo Medical S.L., regarding the potential sale and purchase of the Company’s entire 49% shareholding in Creo Medical S.L. CREO also announced a proposed placing to raise, in aggregate, approximately £5.5 million. The net proceeds of the Placing and the CLNs will be used to provide the Company with additional capital to facilitate Creo’s continued growth and support its commercial momentum whilst it seeks to complete the CME Stake Disposal, whilst also mitigating completion risk.
Comment: Given that Fridays normally have rather less RNS updates from companies, we see CREO filling the void with no less than three of them. Obviously the highlight here is that the shares are up significantly, despite the chunky cash call annouhcement.
Hercules plc (HERC), a leading UK infrastructure and construction services group, announced its audited results for the year ended 30 September 2025. 19% increase in revenue to a record £121.2m, ahead of expectations (FY 2024: £101.9m). Underlying EBITDA* increased 34% to a record £6.4m (FY 2024: £4.7m). Underlying pre-tax profit of £4.0m (FY 2024: £2.6m).
Comment: HERC provides a good illustration of how not all share suspensions are for bad reasons, or have a bad aftermath. Indeed, today we are reminded of how successful the company is in its niche, something which in the era of big government / gravy trains, was rather obvious from the start of its history on the stock market.
Arkle Resources PLC (ARK), the energy metals explorer focused on uranium, announced that interpretation of its Phase 1 geophysical programme is now complete across the Company’s three northern Exclusive Prospecting Licences (“EPLs”) (8290, 8298 and 8995) at its Erongo uranium project in Namibia, with highly encouraging results. These developments combine data from the recent airborne radiometric and magnetic surveys, ground horizontal loop electromagnetic surveys and 2025 assay results.
Comment: Shares of ARK are already up much more than the 60% we were treated to last year, and it would appear that the market is successfully anticipating the good news on the discovery front that the company is delivering on a regular basis.
Zenith Energy Ltd. (ZEN), the listed international energy production and development company, is pleased to provide an update regarding the sale of its fully owned ZEN-260 onshore drilling rig. Further to the Company’s announcement of November 25, 2025, Zenith has agreed terms for the sale of the ZEN-260 for total gross consideration of approximately US$4.3 million to a company operating in the oil and gas sector in the Philippines, including payment of a non-refundable deposit. ZEN said “The transaction represents a strong outcome for Zenith and demonstrates management’s focus on unlocking value from non-core assets while supporting the continued development of our Italian solar portfolio.”
Comment: Today’s rig sale news should be quite a boost for ZEN shares given the way that only those really close to the company will have even been aware that there was a rig to sell. We are also reminded of how the company’s renewable energy efforts in Italy are very much on point in the current environment.
East Star Resources Plc (EST), the Kazakhstan-focused gold and copper exploration and development company, provide an update on recent exploration activities and future work plans in relation to its Snowy gold project. EST said “The latest mapping and rock chip geochemistry is delivering encouraging results at our Snowy gold project. Recent field work by the East Star geological team has included several mapping and sampling transects over the Snowy alteration system with an expansive hydrothermal breccia identified at surface with encouraging gold results. Our low-sulfidation epithermal geological model is based on the geology observed at surface and we are excited to progress the project which has the potential to host a large gold system.”
Comment: Shares of EST have so far in 2026 stalled below the 4p level. That said, one would think that more news like today’s regarding a potentially significant gold system could take the stock over the top well before the summer is over.
