Critica has produced a second high-grade mixed rare earth carbonate from its Jupiter project, closely matching the first product at 57.9% TREO. The latest laboratory result also carried higher magnet and heavy rare earth content, strengthening the case for further flowsheet development ahead of a scoping study.

Morella has established a maiden 5.44 million tonne Inferred resource at Mt Edon containing approximately 8,300 tonnes of rubidium oxide. The estimate gives the project scale, but commercial value still depends on recovery, purification and a viable product route.

Empire Resources has identified rare earth oxide and phosphate mineralisation across three Yuinmery prospects, with new archived-drilling results reaching 1,712.5ppm TREO+Y. The early-stage opportunity now depends on additional assays, follow-up drilling and proof that the material can be upgraded economically.

Turaco Gold has confirmed depth and strike extensions at the Begnopan deposit in Côte d’Ivoire, including several high-grade gold intersections from the first 69 holes of a 113-hole program. The results could support a resource classification upgrade and eventual inclusion of Begnopan in Afema’s ore reserve, but no revised resource or reserve has yet been published.

Terrain Minerals has recorded gold recoveries of up to 93.7% from first-pass metallurgical testing at its Lightning Gold Project, using a conventional gravity and carbon-in-leach flowsheet. The results reduce a key technical uncertainty, although the work remains preliminary and is based on only three RC chip composites.

MRG Metals says grid hand-auger drilling has outlined a visually mineralised 1.6 square kilometre footprint at its Adriano rare earths project in Mozambique. The result expands the exploration picture, but laboratory assays are still pending and no Mineral Resource has yet been established.

Gold Mountain has returned thick, shallow rare earth intersections at Capivara, including 8 metres at 1,513 ppm TREO, while several auger holes ended near mineralisation. The company now plans deeper drilling to determine whether the strongest results continue through the saprolite profile.

McLaren Minerals has reported broad, near-surface heavy mineralisation from 61 holes at its Western Australian titanium project, led by 24 metres at 7.54% HM. The results strengthen the dataset for a resource update, but do not yet establish an Ore Reserve or project economics.

EV Resources has completed its A$1.52 million rights issue as crushing and screening gets underway at the Tecomatlán antimony plant in Mexico. The company now has Vinatas ore and a 200-tonne Chinantla stockpile available for a production-capable proof-of-concept campaign, although first concentrate and binding offtake agreements remain ahead.

Critica has restated its 100%-owned Mt Lindsay project under JORC 2012, defining 19 million tonnes at 1.09% SnEQ and containing about 49,000 tonnes of tin and 28,000 tonnes of tungsten. The estimate gives the Tasmanian project a current resource base, but it remains a mix of Indicated and Inferred material rather than an Ore Reserve.

Encounter Resources has identified a shallow, high-grade niobium zone at Joyce, 6 kilometres east of its Green deposit, with drilling ending in mineralisation. Assays from surrounding holes are due in October and will determine whether the zone has meaningful lateral continuity.

Ariana Resources has re-released its Dokwe drilling update after adding JORC disclosures, leaving the underlying results unchanged. The announcement reports broad gold intercepts, eight tonnes of samples sent to China for feasibility-level metallurgical testing and further work aimed at advancing the Zimbabwe project’s DFS.
