The drilling targeted multiple depositional models and styles, including porphyry/intrusive hosted vein style, banded…
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…

Gold Road Resources Limited (ASX: GOR), a gold production and exploration company, has issued a production update in response to significant rainfall affecting operations at the Gruyere gold mine — located in Western Australia's north-eastern Goldfields. The Gruyere gold mine is a joint venture (JV) between Gold Road Resources and Gold Fields (JSE: GFI), with each holding a 50 per cent interest. Gold Fields manages and operates the mine, while Gold Road Resources maintains a significant investment portfolio. Following substantial and prolonged rainfall in early March, the region experienced further significant and atypical rainfall in the second half of the…
Litchfield Minerals Limited (ASX: LMS), a critical mineral explorer, has discovered new copper-tungsten targets at its Wolfram Hill Prospect within the Mount Doreen Exploration Licence (EL 31305) in the Northern Territory. This discovery, resulting from comprehensive Induced Polarisation (IP) surveys conducted in March 2024, marks a major milestone in the exploration of this site. 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…
Chesser Resources Limited has received first assay results from a recently completed Phase 2 Reverse Circulation (RC) drilling program at the Diamba Sud project in Senegal. Covering 53.2 square kilometres over the gold-bearing Kédougou-Kéniéba Inlier, Diamba Sud is the company’s flagship project. It consists of two blocks referred to as DS1 in the north and DS2 in the south. The Phase 1 drilling program completed earlier in 2019 successfully intersected significant gold mineralisation in fresh rock at all four target areas. The Phase 2 Drilling program within DS1 was completed in mid-July, with a total of 26 RC holes drilled for…
Rio Tinto’s Resolution Copper project in the US has achieved a major permitting milestone with the release of an independently prepared Draft Environmental Impact Statement (DEIS) for the project. The rigorous review, conducted by the US Forest Service over a six year period included broad public engagement. Resolution, one of the most significant undeveloped copper deposits in the world, started the US permitting process in 2013 and the US Forest Service has conducted a comprehensive independent review under the National Environmental Policy Act (NEPA). The publication of the DEIS triggers a further public consultation process over a 90 day period,…
Lake Resources NL (Lake) has discovered multiple lithium brines over a zone of 144 metres (from 172 – 316m) at its 100 per cent owned Cauchari Lithium Brine Project in Argentina. Lithium values from 340 to 538 mg/L were returned from multiple high flow brines with low Mg/Li ratios of 2.73.0. The brine zones and target sand horizon were intersected higher in the sequence than expected. The hole was terminated at 460m due to less permeable clay horizons from 326m, although conductive brines were intersected at 356m and 386m. Detailed sampling with a packer instrument has commenced from 387m up…
Rio Tinto will reduce the annual carbon footprint at its Kennecott Utah Copper operation, located southwest of Salt Lake City in Utah, U.S. by as much as 65 per cent by purchasing renewable energy certificates and permanently shutting its coal power plant. Kennecott’s electricity needs will now be paired with 1.5 million megawatt hours of renewable energy certificates supplied by Rocky Mountain Power, primarily sourced from its Utah allocated portfolio including wind power from Wyoming. The change will reduce the annual carbon footprint associated with the operation by over one million tonnes CO2. Rio Tinto chief executive J-S Jacques said…
Western Australian based company AVZ Minerals Limited's (AVZ) 60 per cent owned Manono deposit has been confirmed as the largest measured and indicated lithium resource in the world.

A second, larger diamond drill rig operated by Foraco Argentina SA has progressed drilling to a depth of 141 metres at Lake Resources NL (Lake)’s 100 per cent owned Cauchari Lithium Brine Project in Jujuy - a province in Argentina’s remote northwest. Located adjacent to world-class brine projects either in production or under development, the new round of drilling aims to unlock further value from the emerging project. The larger diamond drill rig is targeting a sand horizon estimated between 350-450 metres deep and is set drill to 500 metres. Two rigs are now operational at Cauchari and reporting results…
Rio Tinto has approved the next stage in the development of Richards Bay Minerals (RBM) in South Africa through the construction of the Zulti South project. The $463 million (Rio Tinto share $343 million) investment will sustain RBM’s current capacity and extend mine life. RBM currently operates four mines in the Zulti North lease area, a mineral separation plant and smelting facility. The Zulti North orebody grade is declining, hence the Zulti South mine is required to maintain the output of high-margin zircon and rutile, and provide sufficient ore to support TiO2 sales. The Zulti South mine (Phase 1) will…
