Australia’s latest uranium player on the ASX block, Infini Resources, has identified eight radiometric targets in a 1970s-defined anomaly at its Portland Creek uranium project in Newfoundland, Canada.
The company says the targets within its 100 per cent-owned tenure have been distinguished based on desktop studies, geophysical reprocessing of previous survey data and ASTER satellite remote sensing data, combined with an interpretation of previous lake sediment sampling.
Infini’s project embraces 108 square kilometres of Canada’s Precambrian Long Range geological complex and is centred right on top of regional-scale uranium anomalism identified during a Newfoundland government stream sediment sampling program in the 1970s. The company says one geochemical sampling uranium “spike” stands out in government records at an eyebrow-raising 2180 parts per million uranium oxide.
The single grab sample result sits squarely in the centre of the bigger of the company’s two licence areas that strategically covers the zone with the highest uranium values picked up by the more than 40 year-old program. The result was recorded from an extensively exposed, dark porphyritic granite in fault contact with a suite of gneissic rocks intruded by pink granite.
The identification of uranium mineralisation in government samples is exceptional. The data has enabled us to improve our exploration model for the region at a very low cost to the Company. We now have numerous exploration targets supported by radiometric anomalism and mineralised rock samples that allow us to reclassify the Talus area as a prospect and progress the remaining targets. Infini Resources chief executive officer Charles Armstrong
Lake sediment anomalism in the area around the sample site is extensive and extends well beyond the company’s tenure, seemingly along a north-easterly trend measuring about 4km long by 10km wide.
Management says its eight target areas defined to date have been derived from historical radiometric surveying and rock chip sample results and it is now planning new geological programs to include mapping, rock and soil geochemical surveys and desktop geophysics to follow up historical anomalies and other indications.
One key target zone has been identified and it has already been elevated to prospect status and named “Talus”. Perhaps unsurprisingly, it is a well-defined north-south trending zone of intense uranium geochemistry centred around the original high-grade uranium oxide result.
The anomalous “Talus” trend measures about 1500m long and up to 250m wide and contains other rock chip sample values ranging from 37ppm to 865ppm uranium oxide. The trend extends almost the same distance again to the south to include the designated Target 2 and Target 3 and about 300m further north to the weaker Target 5.
The remaining targets are scattered further afield and south of Talus, although while Target 4 and Target 7 are about 1600m south of the trend, they are also directly along strike from it.
Bearing in mind the major advances in geochemistry, analytical sensitivities and reduced detection limits, geophysics including radiometric detection methods, remote sensing and other geological tools available to modern exploration, the company could now reasonably expect to home in on some of its targets with much greater precision.
Infini is an Australian energy metals company focused on mineral exploration in Canada and Western Australia for uranium and lithium and has acquired, or is in the process of acquiring, a total of eight exploration licences. They include 100 per cent interests in the Des Herbiers uranium project in Quebec, the Tinco South Claim uranium-niobium project in Saskatchewan, the Paterson Lake lithium project in Ontario and the Portland uranium project in Newfoundland – all in Canada.
Additionally, it holds a 50 per cent interest in the Tinco North claim with the option of securing the remaining 50 per cent and 50 per cent of the Valor lithium-tantalum-caesium project in Quebec.
In WA, its 100 per cent interests also include the Pegasus lithium-gold project near Ravensthorpe, the Parna lithium project near Norseman and Yeelirrie uranium project near Wiluna.
Management says its identification of a big radiometric anomaly, in combination with widespread uranium geochemical anomalies from a review of historical data, is highly encouraging. It believes it significantly enhances the company’s prospectivity for the discovery of economic deposits of uranium at Portland Creek.
