Catalina Resources rock chip sampling at Santy reveals high-grade tungsten-molybdenum-bismuth mineralization, shifting geological model and setting up drill testing of untested IP anomaly.
Alpha Score of 68 reflects moderate overall profile with strong momentum, strong value, weak quality, moderate sentiment.
Catalina Resources (ASX: CTN) reported high-grade tungsten and polymetallic results from rock chip sampling at the Santy prospect, part of the Tallering project in Western Australia. The findings shift the geological interpretation away from the gold and base-metal targets pursued by earlier explorers.
Executive director Ross Cotton said the results build evidence for an intrusion-related tungsten-polymetallic system. "Our recent work at Santy, including rock-chip sampling and geological mapping, combined with historical drilling and geophysics, is significantly advancing our understanding of the prospect," Cotton said.
Strong tungsten-molybdenum-bismuth mineralisation coincides with a largely untested eastern IP anomaly, Cotton noted. Historical drilling predated the IP survey, leaving the target undrilled under the current model. "This provides a clear focus for our next phase of drilling," he said.
Past exploration at Santy targeted a VMS-style system for gold and base metals. BPM Minerals in 2021 defined a 2.2 km gold anomaly there. Catalina's review of historical records, combined with recent field work, led to the revised interpretation. The company collected 25 rock-chip samples across Santy, Santy South and Nightjar.
Catalina is moving quickly, Cotton said, targeting drilling, broader soil sampling and further fieldwork before the end of 2026, subject to heritage clearances. The next phase includes drill testing of the IP anomaly and a blue quartz zone.
CTN shares closed unchanged at 5.5 cents ahead of the announcement, giving a market capitalisation of roughly A$10 million.
