Rubix Resources Limited has begun drilling at its Paperbark Project in northwest Queensland, targeting a significant geophysical anomaly at Grunter North. The drilling program, marked by the commencement of hole GN25–01 with an end-of-hole depth of 450 meters, aims to test a well-defined chargeability anomaly that measures roughly 600 meters long, 300 meters wide, and 200 meters thick. The anomaly, identified during the 2024 IP survey, is closely associated with surface copper mineralisation, offering fresh opportunities to assess the region’s sediment-hosted and structurally controlled mineralisation models. The drilling initiative is underpinned by a $275,000 grant from Queensland’s Competitive Collaborative Exploration Initiative (CEI) program, the maximum funding available under that scheme. This financial support highlights the strategic importance of exploring critical minerals in a region surrounded by major mining interests including Anglo American, Rio Tinto, and Mount Isa Mines. The planned drilling at Grunter North will assess not only a primary chargeability target but also two additional features, including a target linked to zinc and lead-sulphide at the JB Zone. Technical indicators from the announcement provide key insights for traders. A chargeability anomaly commencing at approximately 250 meters depth is linked to breaks in resistivity and overlays a conductive feature below the Barramundi and Grunter Faults. Geophysical models indicate a zone of weak induced magnetic susceptibility and possible magnetite-destructive alteration, while a northeast trending gravity feature aligns with a local fault line. Such detailed indicators are significant for understanding the potential for copper and base metal mineralisation, comparable to known deposits at Mount Isa and Walford Creek. Investor sentiment appears mixed in light of the news. On the bullish side, the start of drilling with robust government support underscores strong exploration potential in a region recognized as one of the richest mineral provinces globally. The association of the chargeability anomaly with significant surface copper mineralisation adds credibility to Rubix Resources Limited’s exploration thesis. Conversely, from a bearish perspective, the early stage of drilling means that the actual presence and economic viability of mineralisation remain unproven, with inherent risks common to exploration ventures underscored in the forward-looking statements. For those watching the market, the current developments signal an important exploratory step that could shape future prospects in the critical minerals space.
