1. National Standard of China – Spherical Graphite (GB/T 38887-2020)
The micronisation and spheronisation of Kasiya graphite concentrates achieved excellent yields to spherical graphite for the coarse concentrate and typical yields to spherical graphite for the fines concentrate, with room for further optimisation. The spherical graphite from the fine graphite concentrate in particular exhibited a narrow particle size distribution (D90/D10) ratio and both spherical graphite have reasonable Tap Density and typical BET for uncoated graphite. Coating of the graphite is expected to improve (increase) the tap density and improve (lower) the BET specific surface area.

The spherical graphite products were purified with commercially proven acids purification and achieved excellent results with an exceptionally high LOI purity of 99.99%. Assays on key trace elements (Fe, Na, Cr, Cu, Al, Mo) show very low levels.
Further, the low Si and Ca results highlight that high quality Kasiya graphite is well-suited to single stage acids purification. Aggressive dosing in acids purification can result in elevated Ca levels due to precipitation of CaF2, necessitating multiple stages of purification to reduce both Si and Ca impurities. These initial purification results indicate that a single purification stage is sufficient for Kasiya graphite concentrate.
The SPG samples will undergo coating and electrochemical tests to provide baseline data for offtake discussions. The results of these tests are expected in the coming weeks.
Managing Director Frank Eagar commented: “These results clearly demonstrate that Kasiya has the potential to disrupt the China dominated graphite supply chain as a long term, secure source of high quality graphite ex-China. We believe Kasiya graphite will have industry low operating costs and is also one of the largest graphite resources globally holding a significant advantage over its graphite peers. We are very pleased to achieve these outstanding results at this stage of the program and will continue fast tracking our graphite product development and qualification campaign.”

Anglesey Mining #AYM – Following assay results for hole NCZ003, WH Ireland maintains fair value at 5.4p per share
The Northern Copper Zone is shaping up to underpin enhanced mine plans and project economics for Parys Mountain Anglesey recently reported the assay results for the third drill hole completed at its’ Parys Mountain project. Drilling has confirmed the continuity and scale of the Northern Copper Zone (NCZ) which we believe is likely to contribute significant volumes of high-grade ore to mine plans in on-going feasibility studies. Surging metal prices and increased volumes will, we believe, contribute to significantly enhanced project economics once feasibility studies are reported.
The Parys Mountain drill programme has successfully demonstrated the continuity of mineralisation at the NCZ, and it has improved confidence in the Garth Daniel and Central zones. Drilled intervals from the NCZ extend over at least 700m of strike and 400m down-dip, mineralisation is recorded in intervals over 10’s of meters. It is our belief that the drilled intervals lend themselves to low-cost bulk-mining methods and that this will significantly enhance the economic projections for Parys Mountain once feasibility studies are reported. We expect Anglesey will report an updated resource for Parys Mountain that we anticipate will include higher confidence resource categories as well as boosting contained metal. We maintain our fair value at 5.4p per share.

Anglesey Mining #AYM – Further drilling results confirm scale of Northern Copper Zone at Parys Mountain
Anglesey Mining plc (AIM:AYM), is pleased to announce that assay results have been received for the recently completed drill hole NCZ003. Drill hole NCZ003 was the third hole to be completed from the infill drilling program of the Northern Copper Zone (NCZ) and Garth Daniel Zone (GDZ) at the Company’s Parys Mountain Cu-Zn-Pb-Ag-Au VMS project on the Isle of Anglesey in North West Wales.
Consistent both with historical drilling and the recently completed NCZ001 and NCZ002 holes, the assays confirm NCZ003 intersected a significant zone of mineralisation across the NCZ with 90m @ 0.57% CuEq (including internal dilution). Drill hole NCZ003 was terminated prematurely at a depth of 535m due to a large, potentially fault-related void. The last 6 metres of core prior to the 4m void assayed 1.16% CuEq and coincides with previous high-grade assays from historic drilling.
As with the previous two holes in the program, NCZ003 intersected both broad zones of mineralisation and multiple higher-grade zones. Importantly, the drilling is demonstrating good continuity and further supports the integrity of the geological model and drill targeting, with indications of greater mineralised volumes overall.
Key intersections within the broad zone of mineralisation are detailed below:
Northern Copper Zone – Hole NCZ003
- 0m @ 0.51% Cu, 0.06% Zn, 0.03% Pb, 2.16g/t Ag and 0.14g/t Au (0.57% CuEq) from a depth of 389m, including:
- 0m @ 0.80% Cu, 2.19g/t Ag and 0.16g/t Au (0.82% CuEq) from 427.0m
- 0m @ 0.99% Cu, 4.33g/t Ag and 0.15g/t Au (1.08% CuEq) from 449.0m
- 0m @ 0.47% Cu, 1.53g/t Ag and 0.07g/t Au (0.49% CuEq) from 490.0m, including 4.0m @ 0.48% Cu, 2.48g/t Ag and 0.13g/t Au (0.53% CuEq)
- 0m @ 1.20% Cu, 1.10g/t Ag and 0.01g/t Au (1.16% CuEq) from 529m (hole stopped in mineralisation)
***CuEq grades are based on recovery factors and commodity prices as detailed after the tabulated reported assays of this release***
The third drill hole, NCZ003, concludes the on-site portion of the current exploration and infill drilling program and we are expecting litho-geochemical analysis results, from each of the three holes, to be back from the laboratory in Canada in the coming weeks. Subsequently, on the strength of all the data collected and the interpretation thereof, the Company is targeting a resource update on the NCZ, with the aim of converting a significant portion of the Inferred Resource into the higher confidence Indicated category. Based on the Joint Ore Reserve Committee (JORC) guidelines, only Indicated and Measured category Mineral Resources can be converted into Ore Reserves.
Andrew King, Interim Chairman of Anglesey Mining, commented: “Once again, we are very pleased to see the Parys Mountain project delivering some very strong drilling results. It is worth reminding investors that Parys Mountain is demonstrably the largest and most advanced copper project in the UK with substantial resource upside still evident. In addition, the project is favourably located on a previously permitted, brownfield development site with significant existing infrastructure already in place.“
“All three holes in the current program; NCZ001 NCZ002 and NCZ003 have delivered some exceptional high-grade copper intersections within broad thicknesses of mineralisation up to 100m wide. The results continue to support our view that the NCZ provides significant upside for the Parys Mountain project, over and above the 5 million tonne contribution included within the 2021 Preliminary Economic Assessment.”
NCZ – Cross Section 4600mE
Section 4600mE below highlights the position of the recently completed drill hole NCZ002 and NCZ003.
The interpreted outline of the NCZ in the cross-section does not imply an economic outcome, it simply highlights where sulphides have been identified within the Northern Shales with a 0.5% CuEq cut-off. A significant number of the drill holes within this zone have returned consistent zones of higher-grade material, which was a key target of the program. The recognition of a shear zone along the hanging wall of the NCZ could imply a structural emplacement, or thickening of the sequence within the mine environment and will greatly assist with future targeting and drilling.
Importantly, every hole drilled into the interpreted position of the NCZ has intersected broad zones of sulphides; the drilling has demonstrated the predictability of the mineralised zone from the detailed geological model that has been constructed and refined over several years.
The most recent drill hole, NCZ003, targeted the up-dip area above historical hole H17A and has provided important additional information relating to the key lithology Rhyolite B – the emplacement of this unit is closely associated to the mineralising event. This additional information will now be incorporated into the geological model and the resource block model of the NCZ.
Drill hole NCZ003 ended prematurely at a depth of 535m due to faulted ground conditions and the intersection of a 4m void. The last metre of core prior to the void assayed 1.3% Cu and 1.22% CuEq. The location of the void correlates to the contact position of Rhyolite B and the host northern shale unit, which has traditionally been a zone related to higher grade intersections – drill hole A15 intersected 1.6m @ 3.7% CuEq approximately 100m up-dip from NCZ003 and NCZ001 intersected 22.0m @ 3.2% CuEq on section 4800mE (200m along strike).
NCZ – Cross Section 4800mE
Section 4800mE below highlights the position of drill hole NCZ001.
As per section 4600mE, this section also highlights the continuity of sulphide mineralisation across the NCZ. With the completion of NCZ003, the Company has gained a greater understanding of the influence from Rhyolite B on the higher-grade zones of mineralisation.
Section 4800mE also highlights the potential related to the Central Zone with significant intersections from historical 1970’s drilling, including 3.8m @ 8,6% Cu and 6.7m @ 2.4% Cu. The Company believes potential exists for these intersections to link to the 22m @ 3.2 % CuEq (including 4.0m @ 5.2% Cu) in NCZ001.

Cu Equivalent calculated using following commodity prices: Zn – US$3350/t, Cu – US$9523/t, Pb – US$2292/t, Ag – US$25.50/oz and
Au – US$1850/oz
Cu Equivalent calculated using following recovery assumptions for Northern Copper Zone: Zn – 82%, Cu – 93%, Pb – 78%, Ag – 72% and Au – 65%
Sample analysis and QA/QC
All samples generated from the drilling were dispatched to ALS Loughrea, Ireland.
Samples were assayed for multi-element data analysis using their ME-ICP61 package, which includes Ag, Cu, Pb and Zn. The samples were also assayed for gold using their Au-AA23 analysis package. Overlimit assays were then analysed using their Ag-OG62, Cu-OG62, Pb-OG62, Zn-OG62 and ME-OG62 analysis packages.
For QA/QC purposes, Anglesey Mining used the industry standard of inserting 5% Certified Reference Material (CRM) samples, 2.5% Certified Blank Samples (Blanks) and 5% duplicate samples at source. The CRMs were sourced from OREAS Australia.

Quoted Micro 10 May 2024
AQUIS STOCK EXCHANGE
Time to ACT is planning to join the Aquis Stock Exchange later this month and it has launched a fundraising ahead of the flotation. The flotation will take place even if there is no money raised. Time to ACT plans to develop a group of engineering-based energy transition businesses. Middlesborough-based Time to ACT has two subsidiaries. Diffusion Alloys is a long-established diffusion coating business. The technology provides an intermetallic layer that protects metal components at high temperatures. GreenSpur is a much newer business that is developing direct drive generator technology for use in wind power that does not require rare earths for magnets. The Winterflood Retail Access Platform is being used to raise up to £1m. The issue price and closing date have yet to be announced. Investors have to apply for shares via a broker. The minimum subscription is £100.
Cykel AI (CYK) has agreed a bid from standard listed Mustang Energy (MUST). The offer is 1.911 Mustang Energy shares for each Cykel AI share. Both companies’ shares have been suspended since 17 January. The Mustang Energy suspension price was 30.6p, but the bid is based on a much lower share price valuing the company, which has net liabilities, at £1m. That values the bid at 9.37p/share and Cykel AI is valued at £19.2m. Cykel AI is developing artificial intelligence products.
Newbury Racecourse (NYR) increased 2023 revenues by 9% to £19m and reported pre-tax profit improved from £130,000 to £720,000. However, there was a £700,000 exceptional gain relating to the release of a provision included. Cost increases reduced underlying profit. Raceday attendances fell from 141,000 to 130,000. The nursery has increased capacity by 18%. Shaun Hinds will become chief executive on 3 June.
Silverwood Brands (SLWD) executive director acquired 100,000 shares at 20p following the restoration of trading at the beginning of May. The share price recovered by 48.5% to 24.5p, but it is still not back to its suspension price.
Marula Mining (MARU) has appointed a new mine manager at the Larisoro manganese mine in Kenya. Bernard Kiprotich has five years of mining experience in Kenya. Marula Mining is investing in the established Larisoro manganese mining operation by securing a 60% commercial interest with an option to increase it to 70%. There are three shallow open pits. The purchase price is £300,000 satisfied by the issue of 2.4 million shares. Marula Mining will provide investment of $1.5m for equipment to enable production to be increased.
Essentially Group (ESSN) has completed the acquisition of Best Latin Foodstuff Trading for £1.945m in shares at 52.5p each. Catalina Onate, who founded the food importer, has been appointed as an executive director.
Shareholders passed resolutions at the AGM of Supernova Digital Assets (SOL), including a cancelation of the share premium account and authority to buy back shares.
TruSpine Technologies (LON: TSP) chief executive Laurence Strauss has resigned. He was appointed in April 2023.
RentGuarantor Holdings (RGG) raised £35,000 at 274p/share.
AIM
Metallurgical coal company Bens Creek (BEN) says a further court hearing related to the three US operations that are in Chapter 11 bankruptcy protection will be held on 6 June. The court has accepted the proposed Avanti debtor in possession financing and $2m has been drawn down. This provides enough cash until the end of May. The final terms of the facility are being negotiated.
Genedrive (GDR) has raised £2.1m in a placing at 1.5p. This follow’s yesterday evening’s announcement of a fundraising, where the point of care pharmacogenetic testing company wanted to raise £2.5m via a placing. There is also a REX retail offer for up to £3.5m, which closes on 17 May, and a one-for-one open offer that could raise up to £2.1m. If the total amount raised is not at least £6m the fundraising will not go ahead, so a further £3.9m is required. The company’s tests are being commercialised and a direct to consumer strategy pursued in the UK, while there will be distributors in other countries. There will also be investment to improve manufacturing efficiency and to fund regulatory approvals.
Plant Health Care (PHC) generated a 72% increase in revenues to $4.3m in the first four months of 2024. There is cash of $2.3m. The loss could be reduced from $3m to less than $1m this year. A profit is possible in 2025.
Third quarter driver management systems units produced by Seeing Machines (SEE) have gone into 313,662 vehicles, which is 51% higher than the previous quarter. This is more than treble the number in the same period two years and 80% higher than one year previously with more contracts set to contribute. Monitored connections of the Guardian fleet units were 5% higher on the quarter at 59,706.
Push-to-talk and workplace management technology developer Mobile Tornado (MBT) has won a contract through its regional partner to supply technology for a mobile network in the Middle East and Africa, which has more than 50 million customers. Management believes that there should be increasing sales momentum following the deal.
Healthcare services provider Totally (TLY) reassured the market with its latest trading statement. Full year EBITDA was £2.3m, down from £6.9m, and net debt was £800,000 at the end of March 2024. Revenues fell 22% to £106m because of the loss of a contract. Cost reductions and efficiency improvements have offset the tough market. Annualised cost savings of £3.5m are expected.
Bushveld Minerals (BMN) has agreed the conditional disposal of Vanchem to Southern Point Resources Fund 1 for up to $40.6m. The initial consideration is $20.6m. This requires shareholder approval. Southern Point Resources is increasing the interim working capital facility it is providing that is secured on production at Vanchem. This, and a $9m working capital facility, will be offset against the initial consideration and be used to pay creditors. This will leave a cash payment to Bushveld Minerals of $3.5m when the disposal happens. The deferred consideration is based on 25% of distributable free cash flow with a minimum of $1.25m paid for each quarter of the three-year period.
Mothercare (MTC) reported a 13% decline in global system sales last year due to poor trading in the Middle East. Destocking is a problem. There was better trading in the UK and Indonesia. The retailer will improve EBITDA, but Cavendish reduced its forecast EBIDA by 9% to £7m, compared to £6.7m in 2022-23. Refinancing talks continue and a conclusion should reduce the interest bill.
Battery technology developer Ilika (IKA) is raising up to £3.4m at 28p/share to spend on the Goliath solid-state battery. This cash should last at least 12 months. A placing and subscription raised £1.7m and a one-for-26 open offer could raise up to £1.7m more. The open offer closes on 28 May. There will be £750,000 earmarked for the development of the Goliath battery and this supplements the grant assistance obtained. A further £750,000 will be used to increase testing capacity to 0.75MWh/a and for upgrading dry room facilities. Additional cash raised will support further capital expenditure and working capital for Goliath and the Stereax miniature battery.
MAIN MARKET
Packaging manufacturer and distributor Macfarlane Group (MACF) disappointed with its AGM trading statement and lost the majority of the share price gain this year. Prices are falling, but this reflects lower costs, so margins are being maintained. First quarter sales were 9.5% lower, which does reflect a reduction in volumes. There should be improvement in the second half.
Oxford Cannabinoid Technologies (LON: OCTP) plans to cancel the standard listing. Management believes that stockmarket uncertainty is making it difficult to raise cash at an acceptable share price. The development of the drug pipeline will continue. The cancelation date is 6 June.

#SVML Sovereign Metals Ltd – Testwork Delivers Superior Quality Graphite
Graphite circuit feed prepared at Sovereign’s existing Lilongwe laboratory facility has produced high quality concentrates in benchtop and pilot-scale flotation and cleaning
· Four independent laboratories all successfully produced high-grade graphite concentrate averaging over 97% Total Graphite Content (TGC) with flotation recoveries exceeding 90%
· Flotation results demonstrated 1.44% TGC run-of-mine Kasiya ore upgrades to more than 55% TGC rougher concentrate without crushing or milling, process steps typically required for producing graphite concentrates from hard-rock deposits; contributing to the unique low cost characteristics of Kasiya’s saprolite hosted graphite
· Graphite concentrates indicate exceptionally low levels of sulphur compared to typical hard-rock graphite peers – a key metric to qualify as active anode material for lithium-ion batteries
· Results are part of ongoing testwork being undertaken as part of the Company’s graphite marketing and active anode qualification strategy, supervised by Dr Surinder Ghag
· Downstream testwork to produce and characterise Coated Spherical Purified Graphite (CSPG) active anode material continues at German graphite consultancy ProGraphite GmbH
Sovereign Metals Limited (ASX:SVM; AIM:SVML) (the Company or Sovereign) is pleased to announce the results of graphite testwork completed at multiple independent laboratories in Australia, Canada and South Africa.
Graphite flotation and cleaning testwork was conducted on graphite circuit feed from Sovereign’s Kasiya Rutile-Graphite Project (Kasiya or Project) at four different laboratories, which all successfully produced high-grade graphite concentrate (94.9%-97.8% TGC) at high flotation recoveries (91.2%-97.2%).
The testwork demonstrated excellent results using a conventional flowsheet that was consistent across all laboratories, thus confirming Sovereign’s ability to produce a high quality graphite concentrate.
Managing Director Frank Eagar commented: “Our ability to upgrade Kasiya ore at 1.4% graphite to a 55% rougher concentrate without any crushing or milling, highlights more of the unique qualities of Kasiya. There are very limited other graphite projects with these characteristics. The pilot-scale results also confirm that Kasiya produces high-grade concentrates with very low sulphur levels at high recoveries. Simply put, Kasiya will be a standout producer of high-quality graphite concentrate at industry low operating costs.”

The graphite circuit feed provided to the various laboratories was produced at the Company’s existing laboratory facility in Lilongwe, Malawi, where it was screened and separated over a wet shaking table.

The graphite feed grades of 3.5%-4.0% TGC to the graphite circuit are significantly higher than the Mineral Resource Grade of 1.44%, highlighting the ~2.4-2.8-fold upgrading of graphite grades when ROM ore passes through the front-end rutile gravity separation circuit.
This demonstrates the ease of separating the rutile heavy mineral and graphite streams from the front end of the Kasiya Pre-feasibility Study process flowsheet. Subsequently, the two product streams pass into distinct, industry-standard, final product flowsheets. This further highlights the commercial benefits of having both rutile and graphite mineralisation co-existent in the same soft saprolite-hosted orebody.
The first stage of upgrading the graphite feed, rougher flotation, achieved very high rejection (>90%) of waste materials to rougher tails, producing a rougher concentrate with more than 55% TGC and very high recoveries (94%-98%) in laboratory scale testing consistently across all four laboratories. Upgrading the graphite feed at very high recoveries and rejection of non-graphitic minerals without run-of-mine milling is another of Kasiya’s significant advantages, supporting the lowest cost graphite production.
The rougher concentrate was further upgraded through laboratory scale flotation, cleaning and polishing stages, producing high-grade concentrates at high graphite circuit recoveries.

Pilot-scale testwork confirmed the laboratory-scale results with >90% TGC recovery to high-grade graphite concentrates (<180-micron concentrate at 96.9% TGC and >180-micron concentrate at 97.2% TGC).

HIGHLY FAVOURABLE IMPURITY PROFILE
Kasiya concentrates have very low levels of sulphur. Sulphur can be difficult to remove in the purification processes required to produce anode materials. Other major impurities important for anode material purification processes are iron (Fe), silicon (Si) and aluminium (Al). The Kasiya material has exceptionally low levels of all of these impurities. Benchmarked against the Chinese Standard (China dominates the supply of graphite for battery anodes) this could potentially lead to significant commercial advantages during purification and Kasiya’s potential as a long term secure source of graphite ex-China.
