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…

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…
ELYSIS has selected Rio Tinto's Alma smelter, located in Quebec in Canada, for the first installation and demonstration of its inert anode technology at a commercial size of 450 kiloamperes (kA), which is a common capacity for modern, full-scale smelters. ELYSIS is a joint venture company, led by Rio Tinto and Alcoa, that is working to commercialise a new technology to make aluminium that eliminates all direct greenhouse gases (GHGs) from the traditional smelting process and instead produces oxygen. As part of its technology development and scale-up, ELYSIS will install industrial inert anode prototype cells at the end of an…
Resolute Mining Limited's Mining Lease for the Bibiani Gold Mine has been restored due to Ghana’s standing as the largest gold producer in Africa and among the top seven producers in the world, and the need to maintain investor confidence globally and in particular maintain Ghana’s reputation as the preferred destination for mining investment in Africa. The Ghanaian Honourable Minister for Lands and Natural Resources, Hon. Samuel A Jinapor, MP has restored the Mining Lease subject to the following: The Company and the holder of the Mining Lease, Mensin Gold Bibiani Limited (MGBL) (a subsidiary of the Company), acknowledge and…
Challenger Exploration Limited has announced results from a series of drillholes from the company’s flagship Hualilan Gold project in San Juan, Argentina. The results are from the first seven holes from a series of 26 completed holes designed to test for extensions to the: High-grade mineralisation in the Magnata Fault at depth and in both directions along strike; The high-grade Magnata Manto both up and down-dip and along strike; and The broad zones of intrusive hosted mineralisation north and south of the Magnata Fault. Given the results, and the visual mineralisation (skarn alteration with sulphides) logged in many of the…
South African focused gold developer, Theta Gold Mines Limited, has announced its Maiden Underground Prefeasibility Study (PFS) for the Beta, Frankfort, and CDM mines, all of which form part of the Central Northern area and now collectively referred to as TGME Underground Project. Chairman of Theta Gold, Bill Guy, said the TGME Underground PFS ‘clearly demonstrates’ that the extensive flat high-grade narrow reef systems of East Transvaal Goldfield can be mined economically, and modern mechanised mining and metallurgy can deliver strong project economics. “Now that the company has generated a PFS for the TGME Underground Project, we can optimise our…
B2Gold Corp. has commissioned the world’s largest off-grid solar-battery hybrid system for the mining industry, at the Fekola gold mine in Mali, West Africa. The solar-battery hybrid plant was integrated and commissioned successfully with the existing power plant operation, and the solar plant is on course to be 100 per cent complete by the end of June. The Fekola gold mine operates 24-hours a day. During the daytime, the new 30-megawatt solar plant allows three out of six heavy fuel oil generators to be shut down; the energy production of the residual three generators could also be significantly reduced. The…
The Cabeza de los Gatos waste rock pile, left from mining activities in the town of Tharsis (Huelva) in Spain, underwent a rehabilitation process consisting of remodelling the slope of the pile, applying liming materials and then a layer of soil. Trees and shrubs typical of the area were planted and a hydroseeding with a mixture of shrub and herbaceous seeds was applied. 12 years later, a study led by researchers from IRNAS-CSIC, in collaboration with Sabina Rossini Oliva, a researcher from the University of Seville and the Environment and Water Agency of Andalusia (AMAYA), has proven the effectiveness of…
Production of battery-grade lithium from waste rock has commenced at a lithium demonstration plant at Rio Tinto’s Boron mine in California, USA. An initial small-scale trial in 2019 successfully proved the process of roasting and leaching waste rock to recover high grades of lithium. Rio Tinto said the demonstration plant is the next step in scaling up a breakthrough lithium production process developed at Boron, to recover the critical mineral and extract additional value out of waste piles from over 90 years of mining at the operation. The demonstration plant has a design capacity of 10 tonnes per year of…
