RC1 boosts Redcastle gold potential
Special report: Assay results from the final phase of 2025 RC drilling at Queen Alexandra prospect within the Redcastle Resources' namesake gold project support the foundations for anticipated future mine development.
Redcastle has received final assays from the 2025 RC drilling program
Higher grade, shallow mineralisation in the Kestrel Lode have expanded its areal extent
Resource preparation is underway at Queen Alexandra and Redcastle Reef
The 19-hole program for 1853m was designed to refine the Kestrel Lode's geometry and grade, particularly within the near-surface zone.
The Kestrel Lode is considered most amenable to a positive cashflow development scenario resulting from early-stage open pit mining.
About 40 of 51 drill holes have intersected mineralisation of >2g/t including 2m at 7.80g/t gold from 66m and 6m at 2.70g/t from 36m, complementing the previous first phase results.
Redcastle Resources (ASX:RC1) says integrating the 2025 assay dataset has further defined the Kestrel Lode characterised by 24 high-grade intercepts over a minimum 2m width.
Meanwhile, deep gold mineralisation in the eastern portion of the Redcastle Reef prospect is expected to strengthen the likelihood of it becoming a satellite development to Queen Alexandra with notable results including 16m at 1.20g/t gold from 84m and 1m at 7.42 g/t from 107m.
Transformative 2025
The Redcastle Project is ~58 kilometres east-southeast of the Gwalia Gold Mine and centrally located within a regional 'golden circle', an area delineated by multi-million-ounce gold interests in the highly prospective Leonora-Laverton portion of the greenstone belt of the eastern Yilgarn.
With strong gold grades, scoping work and a MRE update underway, RC1 is well-positioned for a transformative 2025.
Resource prep in the works
RC1 non-executive chairman Raymond Shaw said the company continued to be very excited about the results of 2024/2025 drilling.
'The assay results underscore the very genuine opportunity Queen Alexandra presents to our company,' he said.
'Work is now focused on assessing the material impact of all drilling results upon the JORC compliant MRE at Queen Alexandra and preparing our maiden JORC compliant MRE at Redcastle Reef.
'These will serve as foundations for anticipated future mine development, commencing with a bulk sampling program for metallurgical and processing studies,' Shaw added.
'We envisage recovery of near surface (6-10m) high-grade gold mineralisation as an early-stage to developing a larger open pit mining operation, using less capital-intensive models including accessing third-party processing capacity available within the district.'
What's next?
Drilling results at Redcastle Reef demonstrate that the majority of mineralisation is concentrated within 60-70 metres of surface, except towards the eastern extent where, as evidenced by intercepts from RC281 and RC282, mineralisation extends to about 100 metres depth.
The Kestrel Lode is the most extensively delineated mineralised zone identified to date within the Queen Alexandra project.
Subject to the outcomes of a formal scoping study and further technical assessments, the Kestrel Lode has the potential to support a conceptual open pit development to depths of at least 70m, targeting near-surface high-grade oxide and transitional material.
An updated, independent resource for Queen Alexandra is being prepared on the basis of the extensive RC and diamond drilling assay database and is scheduled for completion in June 2025.

Award-winning journo disappeared for spruiking on HotCopper
It's hard not to marvel at schemes when they're so brazen. Former journalist Ross Dunkley hatched a fun one, using pseudonyms to post about ASX-listed gold miner Auric on the pump-and-dump website HotCopper. Dunkley was Auric's head of investor relations. He also used usernames 'LENIN' and 'GOLDATWIDGIE' to make sterling posts like 'What a sexy little beast Auric is' and 'I'm a newby here and I've just bought a sizeable package of Auric shares'. There were more than 300 posts like it.

ASX to open lower; Wall Street sinks as Trump threatens Iran
Australian shares are poised to open lower as Wall Street took fright from an escalation of the Israel-Iran conflict with Donald Trump demanding 'unconditional surrender' from Iran. The S&P was down nearly 1% and oil rose. West Texas Intermediate rose over $US74 a barrel. Weak economic data from the US also weighed on investors. Retail sales fell for a second straight month, suggesting anxiety over tariffs and their finances prompted consumers to pull back after an early-year spending rush. Industrial production also dropped as utility output declined and manufacturers struggled for traction against a backdrop of cooler demand. Confidence among US homebuilders hit the lowest since December 2022. 'Investors should still expect some volatility in economic data due to lingering effects of trade policy,' said Bret Kenwell at eToro. 'The economy and the consumer are holding up for now, but there are signs of vulnerability. That could present risks in the second half of the year — particularly if we see a further slowdown in jobs or spending.' Market highlights ASX futures are pointing down 32 points or -0.4 per cent to 8513 All US prices are as of 1.30pm New York time. Today's agenda This morning sees the release of the Westpac-MI leading index at 10.30am. There will also be New Zealand consumer confidence and trade deficit data. Overseas, the Euro zone and Britain will both issue CPI data at 7pm. The US Federal Reserve rates decision comes in the early hours of Thursday.

Closing Bell: ASX edges lower as traders wait for Israel-Iran clarity
ASX slips 0.04pc, pushed lower by utilities sector Gold index props up materials sector, adding 1.11pc Uranium stocks continue to climb The Australian market slid in the face of global headwinds today, losing 0.04%. Most of the sectors were dragging, particularly utilities which shed 0.95%. The energy sector also moved lower despite another round of outsized gains in ASX uranium stocks, up once again after making double digit moves yesterday. Bannerman (ASX:BMN) added 11%, Lotus (ASX:LOT) 10%, Deep Yellow (ASX:DYL) 5%, Paladin (ASX:PDN) 4% and Boss (ASX:BOE) just under 3%. The rally was sparked by Sprott, a Toronto-based asset management firm, signalling it intends to buy US$200 million of yellowcake through its Sprott Physical Uranium Trust. That's double what the firm originally intended to raise for the purchase, having accepted US$100 million in oversubscribed offers – a reflection of strong investor interest in uranium. Uranium's spot market is fairly illiquid, with most purchases being made through long-term contracts directly between producers and utility companies. But that means on-market purchases can have pronounced impacts on spot prices, which in turn influence prices paid under contracts. The only other spots of optimism on the market today came in resources, where gold stocks pushed the materials sector into the green after posting a 1.11% gain. Oil tanker companies feel the heat of Iran-Israel conflict A report on X from claims tanker firms are already feeling the pressure from open hostilities between Israel and Iran despite the Strait of Hormuz remaining open at present. Tanker firms are pulling back from Gulf routesâ€'even without a Hormuz closure. Freight rates +20%, war-risk insurance up $3â€'8/bbl, and VLCC bookings plummet. This isn’t just a headline scareâ€'real volatility is brewing. #oiltankers #StraitOfHormuz #shippingrisk #energysecurity … â€' (@OilandEnergy) June 17, 2025 With US President Trump cutting his G7 appearance short and taking to Truth Social to suggest civilians should evacuate Tehran, a ceasefire certainly doesn't seem forthcoming. About four hours ago the Israeli Defence Force warned missiles had been launched at Israel from Iran, cautioning citizens to seek shelter. Reuters reports Tehran has asked several Gulf states to pressure the US to intervene, ostensibly to push Israel to accept an immediate ceasefire. According to several sources, Iran has signalled its willingness to be flexible in nuclear talks with the US if a ceasefire is reached. An Iranian source claims Iran is serious in its desire for a ceasefire, fearing an escalation could spread across the volatile region and spark a wider conflict. Any increase in tensions is likely to have a big impact on oil prices, and potentially drive-up inflationary pressures just as global economies begin to ratchet down monetary policy.

While non-binding at this stage, VR8 has agreed to provide 100,000 tonnes of vanadium-rich direct shipping magnetite ore per month, subsequently unlocking early-stage revenue to support staged development of Steelpoortdrift. Metgasco (ASX:MEL) released its monthly gas production results for its assets in the Odin and Vali gas fields, notching an 8% increase on the previous month to produce 100MMscf of raw gas. Pivotal Metals (ASX:PVT) went into a trading halt today, following a price query letter from the ASX and ahead of release of a new set of exploration results, expected on Thursday.
