22 May 2025 | West Perth, WA – Kali Metals (ASX:KM1) has expanded its Marble Bar Gold Project in the Pilbara by 28.8km² following the acquisition of exploration licence E45/6389, bringing the project’s total landholding to approximately 96km².

The newly acquired tenement sits directly along strike and immediately north of Kali’s existing 9.5km gold-in-soil anomaly, where previous rock chip sampling returned grades of up to 4.0g/t gold. Kali believes the mineralised trend extends into the new area and intends to begin exploration immediately, with heritage approvals already in place.

Managing Director Paul Adams commented:

“This acquisition not only consolidates our landholding but also significantly strengthens the exploration potential at Marble Bar. With gold prices recently reaching record highs, we’re maintaining a clear focus on advancing this highly prospective area.”

Kali also announced it has recently completed its most extensive surface sampling program to date, collecting 299 rock chip samples across the project. Assay results are expected in the coming weeks.

Acquisition Terms:

• $20,000 cash and scrip consideration (3.5M shares)

• Two deferred share payments tied to JORC resource milestones:

  • 100,000oz and 250,000oz gold at 0.5g/t cut-off within four years

The Marble Bar Project is strategically located near Calidus Resources’ Warrawoona/Klondyke operations and forms part of Kali’s broader gold and lithium portfolio across Australia’s key mineral belts.

22 May 2025 | South Perth, WA – Astral Resources (ASX:AAR) has delivered outstanding metallurgical results from its Feysville Gold Project, with gold recoveries of up to 98.1% confirmed from initial testwork at the Kamperman and Rogan Josh deposits. The results support the inclusion of these satellite deposits in the upcoming Mandilla Pre-Feasibility Study (PFS).

Five composite samples from Kamperman and two from Rogan Josh underwent gravity and cyanide leach testing. Three Kamperman samples returned an average recovery of 98.1%, confirming free-milling characteristics. The remaining two, which contained elevated copper, recorded 87.9% but are expected to improve with higher cyanide concentrations in follow-up tests.

Key Results:

• Kamperman: 3 samples averaged 98.1% recovery; 2 samples averaged 87.9% (high copper impact)

• Rogan Josh: 2 samples averaged 91.5% recovery at an average head grade of 0.70g/t Au

• Low reagent consumption and rapid leach kinetics across both deposits

Managing Director Marc Ducler stated:

“These results clearly demonstrate that the simple, low-cost processing route proposed for Mandilla will also suit ore from Kamperman and Rogan Josh. This is a key step toward incorporating Feysville into the broader Mandilla mine plan.”

The combined Feysville resources now total 5Mt @ 1.2g/t Au for 196koz, strengthening Astral’s consolidated Mineral Resource base of 1.76Moz.

Additional assay results from RC and aircore drilling at Feysville are due later this quarter, alongside ongoing in-fill and extensional drilling at the nearby Iris and Hestia deposits.

21 May 2025 | Alstonville, NSW – Polymetals Resources (ASX:POL) has confirmed that redevelopment of its Endeavor Silver-Zinc Mine is progressing on schedule and within budget, with commissioning well underway and first cash flow expected in June.

Following the completion of major site works and infrastructure upgrades, the site has entered full commissioning. Crushed ore is being hoisted and stockpiled, with wet commissioning of the plant in progress and ore processing scheduled to begin next week.

Key highlights:

• First ore crushed and hoisted to surface

• Over 40,000 tonnes of ore stockpiled underground

• Site targeting 65,000t/month processing rate in H2 2025

• First mining of high-grade silver ore set for July 2025

Executive Chairman Dave Sproule said:

“We’re proud of the rapid, in-house development at Endeavor — a rarely achieved feat at this scale. First processing is imminent, and our shareholders are seeing real value for money.”

In parallel, diamond drilling continues at the Carpark prospect, targeting extensions of the Main Lode. Results will be released once the current program is completed.

Polymetals is aiming to become a long-term base and precious metal producer from the Cobar Basin, with the Endeavor restart marking a critical milestone in that journey.

21 May 2025 | West Perth, WA – Yandal Resources (ASX:YRL) has confirmed broad zones of gold mineralisation at the Siona Discovery, part of its Ironstone Well-Barwidgee Project in WA’s northern Goldfields, and is now preparing to launch a major 12,500m aircore drilling program at the nearby Caladan prospect.

Diamond drilling at Siona returned:

• 16.3m @ 0.5g/t Au from 322.2m (25IWBRD0003)

• 29.1m @ 0.4g/t Au from 282.9m (25IWBRD0010)

• 6.4m @ 1.5g/t Au from 103.5m, including

  • 0.4m @ 12.7g/t Au (25IWBDD0009)

• 116m @ 1.0g/t Au from 97m (24IWBRD0039 – RC + diamond tail)

These results build on the broad, low-grade halo with internal high-grade zones identified in earlier RC drilling. Geological modelling suggests gold mineralisation is controlled by deformation along and within the New England Granite intrusion.

Managing Director Chris Oorschot said:

“We’re now armed with a much clearer understanding of the Siona system. With the full extent of the granite under Yandal’s control, we’re shifting focus to testing new structural targets that could deliver larger-scale discoveries.”

Next steps:

• Caladan aircore drilling begins late May

• Follow-up aircore at Salusa and other New England Granite (NEG) targets

• Heritage surveys scheduled for late May / early June

• RC drilling to resume post-aircore to test deeper high-grade trends at Siona

Yandal sees the NEG as a regional-scale gold system, with visible gold, strong alteration, and favourable structural controls now confirmed through diamond drilling.

21 May 2025 | West Perth, WA – Rox Resources (ASX:RXL) has achieved a major milestone in its metallurgical test work, confirming gold recoveries of 91.6% to concentrate from samples at its flagship Youanmi Gold Project in WA’s Mid West.

Conducted as part of the Definitive Feasibility Study (DFS), bulk flotation tests also returned concentrate grades of 49.9g/t Au, with up to 62.6% additional gold recoverable from tailings via cyanide leach. Test work using the Albion Process™ is now underway to optimise overall recovery.

Key Results:

• 91.6% gold and 98.3% sulphur recovery to concentrate

• Tailings leach recovery: 35.8–62.6%, with low reagent use

• Albion Process™ to improve recovery from semi-refractory ores

• Final gold recoveries expected to exceed PFS assumptions

Managing Director Phillip Wilding commented:

“It’s exciting to see recoveries exceeding our Pre-Feasibility Study expectations. The Albion Process could deliver further upside while lowering processing costs, supporting a compelling case for development.”

The metallurgical program, which began in January, will feed directly into Rox’s DFS due in November 2025. The work covers the major ore lithologies that comprise over 95% of the planned plant feed and is key to optimising the process flowsheet.

Additional dewatering, approvals, and resource updates are progressing in parallel as Rox works toward a production decision.
