Intra Energy Corporation Limited (IEC), an environmentally responsible mining and energy group, has announced compelling lithium, tantalum, niobium, caesium, and tin assays from rock chip sampling at the Maggie Hays Hill (MHH) project. These results significantly enhance the project's lithium prospectivity and validate IEC's exploration strategy. The latest round of sampling, conducted over the most prospective section of outcropping pegmatites, revealed averaged lithium assays of 503 ppm, indicating the presence of lithium-rich pegmatites. Additionally, encouraging caesium and tantalum values, with average assays of 139 ppm and 107 ppm respectively, suggest the potential for multiple mineralisation targets. These findings, along with…

The recent IP survey has identified two large and highly promising chargeability targets located to the north and south of the existing mineralised zones. These findings suggest the potential for substantial extensions of the known mineralised reef at depth and along the strike to both the…
Intra Energy Corporation Limited (ASX: IEC) has announced the discovery of significant lithium anomalies at its Maggie Hays Hill (MHH) project in Western Australia's Lake Johnston Greenstone Belt. This discovery places the company at the forefront of lithium exploration, with the potential to impact the global lithium supply chain. A recent soil sampling program revealed two major lithium anomalies, with the primary anomaly stretching over 2,500 metres in length and 300 metres in width. The secondary anomaly measures 1,300 metres by 300 metres. These anomalies are notable for their high lithium values, reaching up to 248ppm Li2O, and are associated with tantalum and caesium, elements indicative of highly prospective…
Ora Gold Limited (ASX: OAU) has announced promising initial assay results from its 2024 RC drilling program at the Crown Prince Prospect within the Garden Gully Gold Project in Western Australia. The results, particularly from the Southeastern Zone (SEZ), highlight significant high-grade gold mineralisation, marking a significant step forward in the exploration of this key growth area. The drilling campaign, initiated in early February 2024, has yielded encouraging results, including an exceptional intercept from drill hole OGGRC662 — 15 metres at 9.91g/t Au from 88 metres, with a higher-grade section of two metres at 54.17g/t Au from 100 metres. Other…
Rio Tinto has announced the company will conduct a strategic review of the ISAL smelter in Iceland, to determine the operation’s ongoing viability and explore options to improve its competitive position. ISAL is expected to remain unprofitable in the short to medium term in the challenging conditions facing the aluminium industry, due to the smelter’s uncompetitive energy costs and historically low aluminium prices. Rio Tinto will continue discussions with the Government of Iceland and power provider Landsvirkjun on how the smelter can return to profitability and become competitive in the global market. Rio Tinto Aluminium chief executive Alf Barrios said…
Glencore has signed a five-year agreement for the supply of cobalt hydroxide for use in lithium-ion batteries. Under the terms of the new supply contract, Glencore will provide up to 21,000 tonnes of cobalt contained in cobalt hydroxide between 2020 and 2024 to Samsung SDI . Glencore produced 42.2 kilotonnes of cobalt in 2018, mainly as a by-product of copper mining. The cobalt will be sourced from Glencore's Katanga and Mutanda operations which are located in the Democratic Republic of the Congo (DRC). Glencore and Samsung SDI state that they are committed to ensuring the ethical and responsible production and procurement of…
