Cullen Resources Advances Yardilla Drilling and Finland JV Progress

Yardilla Gold Project Drilling Ready to Launch

Cullen Resources (ASX:CUL) has secured clearance from Traditional Owners for key target areas at its Yardilla Gold Project in Western Australia, paving the way for air core drilling to start in early May. The upcoming program will focus on historical gold anomalies at the Cleanthes and Lila prospects, which have seen limited shallow drilling to date but returned multiple zones exceeding 0.1g/t Au, including several over 1g/t Au, alongside anomalous copper, silver, and tungsten. These targets lie along a 25km trend of thrust sheets and faults at the Proterozoic-Archaean boundary, a structural setting that Cullen believes holds significant upside potential.

Managing Director Chris Ringrose expressed satisfaction with the heritage survey process, highlighting the company’s ongoing collaboration with the Ngadju Traditional Owners. This relationship is expected to facilitate further exploration across the Yardilla tenure, which now comprises a substantial combined land package of approximately 325 sq. km east of Norseman. Cullen’s renewed focus on Yardilla follows a series of data compilations and field reviews that have refined target generation for gold mineralisation.

Finland JV Drilling and Geochemical Programs Progress

Meanwhile, Cullen’s 20% joint venture partner Capella Minerals Limited (TSX-V: CMIL) has completed 1,946 metres of diamond drilling across nine holes at the Killero E gold-copper project in Northern Finland’s Central Lapland Greenstone Belt. Assay results are pending, but the drilling represents a first-pass test of a historical Base of Till geochemical anomaly linked to a prominent structural corridor and mafic units. Capella has also initiated Base of Till sampling programs on the Seisunselka and Jolhikko gold targets, with further drilling planned for later in 2026.

Cullen’s involvement in this JV builds on its strategy to leverage partnerships for early-stage exploration in prospective terrains beyond Australia. The Killero E project is situated within a broader regional context where major players like Rupert Resources operate, noting that Rupert is currently being acquired by Agnico Eagle (NYSE: AEM, TSX: AEM), adding potential strategic interest to this district.

Copper Anomalies at Wongan Hills Add Base Metals Interest

Back on home soil, Cullen received encouraging assay results from reconnaissance RC drilling at the Wongan Prospect in the Wongan Hills Greenstone Belt, WA. Drill hole WHRC025 intersected strongly anomalous copper grades (5m at 1915 ppm from 80m and 5m at 1555 ppm from 95m) at an ultramafic/basalt contact, marking the highest copper values recorded by Cullen in this area beyond known laterite anomalies. The copper mineralisation remains open along strike, providing a compelling target for follow-up work.

Marymia Project Access Secured, Exploration Pending

Cullen is advancing two exploration licence applications in the Marymia Inlier, located near Catalyst Metals’ Hermes gold deposit and the Plutonic Mine. An access agreement has been signed with haul and access road owners, clearing a key hurdle for exploration to commence once the licences are granted. The planned program aims to apply a “Hermes-type ore model” through mapping and sampling, targeting gold mineralisation in this granite-greenstone terrane.

Financials and Corporate Movements

Exploration expenditure for the quarter was $243,000, covering heritage surveying, data review, and planning for Yardilla drilling. Cullen ended the quarter with $609,000 in cash, down from $984,000, reflecting ongoing investment in exploration activities. Executive and non-executive director payments totaled $81,000. Cullen also retains a 1% FOB royalty over future production from the Catho Well Channel Iron Deposit near Onslow, which could provide future cash flow if mining proceeds.

Cullen’s portfolio remains diversified across multiple joint ventures, including the Mt Eureka JV with High Tech Metals (ASX:HTM) and the Killaloe JV with Lachlan Star (ASX:LSA), although no work was reported on Killaloe during the quarter. The company continues to monitor and potentially divest non-core projects such as Bromus South and Cue, maintaining Yardilla as the primary focus.

The company’s current exploration momentum builds on its earlier announcements outlining drilling campaigns across Australia and Finland, including the planned air core drilling at Yardilla and Capella’s maiden diamond drilling in Finland, both of which are now advancing with tangible field activity.
