Latest Portable Xrf News

Hawk Resources has acknowledged that historical portable XRF readings underpinning its Olympus scandium story lacked calibration, quality-control and detection-limit records, and were not reliable indicators of scandium grades. The company maintains its original disclosure complied with ASX rules and the JORC Code, but says it will no longer use the historical results.

Alvo Minerals has expanded its Bluebush heavy rare earth project in Brazil, with new ground, encouraging clay intercepts and Florence drilling advancing toward a maiden resource. But quarter-end cash of A$227,000 covered only 0.28 quarters of reported outgoings before a subsequent A$1 million placement and option exercises.

RareX has reported stronger Cummins Range recoveries, a preliminary 74-metre copper sulphide zone at Khaleesi and a submitted proposal for Kenya’s Mrima Hill project. The gains come with two important qualifications: Khaleesi assays remain outstanding and the company reported only 2.13 quarters of estimated funding at September-end.

Alice Queen’s first 20 Horn Island RC holes all intersected mineralised geological features, with assays returning grades as high as 68.0g/t gold and extensions beyond the existing resource boundary. Nine assays remain pending as the company prepares to assess whether the results can support a larger resource and advance its development case.

El Dorado Goldfields has begun testing a 180km² Guyana land package after securing an option to acquire a 90% interest in the Oko North and Oko South projects. Early rock-chip assays reached 2.32 g/t gold, but the greenfields projects remain undrilled and have no defined resources or reserves.

Green & Gold Minerals has identified follow-up targets across Copper Hills, Elizabeth Bluffs and Mt Wandoo after a quarter of strong polymetallic and gold exploration results. The company held $2.268 million in cash at quarter-end, with assays from the latest 3,000-metre Mt Wandoo program expected from late November.

Pinnacle Minerals is seeking shareholder approval for a securities-funded acquisition of five early-stage tungsten projects in Utah, alongside a proposed A$1.3 million placement. The transaction would bring new management, substantial exploration commitments and a sharply larger pool of performance securities.

Raptor Metals has completed its first Chester drilling campaign, with broad copper intersections and electromagnetic conductors pointing to follow-up targets across the Canadian project. The company is now preparing 2,800 metres of maiden drilling at Silverjack and Turgeon while holding $1.325 million in cash.

Australian Rare Earths has produced its first Mixed Rare Earth Hydroxide at the Koppamurra pilot plant while extending an interpreted carbonatite system at Overland by roughly 5km. The operating progress comes with two important qualifiers: Koppamurra still needs further product refinement and Overland assays remain pending.

Infini Resources has launched its largest exploration campaign at Portland Creek, while maiden Saskatchewan drilling awaits assays and the company reports only 0.43 quarters of funding at current outgoings. The ASX-listed explorer ended September with A$1.897 million in cash after spending A$3.7 million on exploration during the quarter.

Critical Resources has expanded its Suriname gold strategy to three projects covering about 228 km² under exclusivity, while advancing exploration in New Zealand and Canada and laboratory-stage battery technology. The company ended September with A$1.58 million in cash and an estimated 1.87 quarters of funding based on reported outgoings.

Nex Metals has assembled a potential 3,021 km² Western Australian exploration portfolio through its WTAC joint venture, while preliminary Kookynie test work lifted laboratory gold recovery to 71%. The expansion comes with important conditions: most tenure remains pending, and the processing case still requires further technical and economic work.
