King River taps high-grade gold while eyeing NT copper-gold riches
King River Resources has uncovered more high-grade gold in the latest round of drilling at its Kurundi project in the Northern Territory, while also firming up two iron oxide copper-gold (IOCG) targets it plans to test this month at its nearby Kuiper prospect. The company today reported results from 13 reverse circulation holes at Kurundi, with one of the standout hits coming from a newly discovered structure 300 metres northeast of the Kurundi Main prospect. One hole pulled up 4m at 1.43 grams per tonne (g/t) gold, including 2m going 2.79g/t from a shallow 9m depth. King River says the mineralisation remains open both at depth and along strike and appears spatially associated with historic alluvial gold workings in the area. The newly discovered zone adds to a string of earlier high-grade hits at Kurundi Main, including 7m at 6.35g/t gold from 25m, with 1m at a blazing 35.26g/t gold, 6m at 4.77g/t from 29m with 3m at 9.28g/t, and 3m going 8.3g/t from 35m that included 1m at 15.5g/t. Five new holes were drilled under the central Kurundi Main structure, intersecting veining and structure consistent with previous results, though grades were variable. Notably, another hole returned improved values of 7m at 0.49g/t gold, including 2m at 1.12g/t, pointing to the potential for a down-plunge northerly extension that remains open at depth. Another four holes were completed to probe the southern extent of the main mineralised zone, though structural complexity, including an offsetting fault, may be obscuring the true extent of the mineralisation in that area. The company also has its eye on the Kuiper target, where soil sampling has produced encouraging pathfinder signatures over a pair of coincident gravity and magnetic anomalies. The targets lie within Warramunga Formation-equivalent rocks under about 10m of Cambrian cover, similar to the host rocks of nearby IOCG deposits such as Emmerson Resources' Hermitage and Edna Beryl projects. At Kuiper West, soil geochemistry showed anomalism in key IOCG trace elements such as gold, copper, silver, bismuth and arsenic. The bismuth anomaly aligns with the heart of the gravity anomaly, an encouraging indicator given bismuth's association with Tennant Creek-style IOCG systems. The company believes the data supports a compelling interpretation of ironstone-hosted mineralisation beneath the geophysical targets and says drilling at Kuiper is scheduled to kick off this month.

Tennant to launch into two large-scale Top End gold targets
Tennant Minerals will launch into two large-scale gold and copper targets identified from historical exploration completed in the 1970s. The company's Babbler gold and Wedge copper-gold prospects sit near its flagship Barkly copper-gold project, about 35 kilometres east of the Top End's renowned Tennant Creek mining region. Babbler sits on a prominent positive magnetic anomaly adjacent to a gravity low. A series of percussion drill holes were hammered about 50 metres apart into its ground in the 1970s by the former mining company, Noblex. Some drill holes were followed up with diamond tails to test deeper geophysical anomalies. The drilling program identified widespread gold anomalism and significant intercepts of more than 0.15 grams per tonne (g/t) gold across a one square kilometre area. 'No significant exploration has been conducted on the project since (the 1970s), possibly because the host rocks were not typical of the Tennant Creek-style copper-gold mineralisation targets at the time.' Tennant Minerals chief executive officer Vincent Algar Historic gold results from the drill program consisted of 13m grading 0.48g/t from 90m, including 7m at 0.68g/t from 94m, 22m running 0.42g/t from 33m, including 6m at 0.61g/t from 33m, a promising 3m slice going 2.91g/t from 71m and a 14m section at 0.31g/t gold from 81m. A further hole returned anomalous copper and gold, assaying 12m at 0.57g/t gold from 6m, including 3m grading 0.51g/t gold, and 453 parts per million (ppm) copper from 86m. The hole also returned a 56m copper interval going 251ppm from 49m, with 2m at 855ppm from 72m and 2m at 1200ppm copper from 92m. The gold grades were considered too low for follow-up at the time, due to production demands in the area and a subdued gold price. Tennant believes the widespread gold anomalism outlines a potential kilometre-scale gold system target that is now worth investigating.
