Infini Resources (ASX: I88) believes it is now hot on the trail of a Canadian uranium deposit at its Portland Creek project in Newfoundland after an initial field program threw up samples assaying as high as 1301 parts per million.
The company says the highly-anomalous spectrometer readings at surface found during the field program supports its belief that a potentially significant uranium occurrence may be hidden beneath the talus. Its extensive recent survey also included 12 rock samples and 168 soil and bio-geochemistry samples, with the biologics being taken from black spruce in Infini’s three priority uranium target areas and 1831 spectrometer point traverse readings.
Sampling and spectroscopy measurements were taken along east-west lines, with spacings varying between 100m and 200m. Both soil and bio-geochemical samples were taken to help determine which method would prove most useful for detecting uranium mineralisation in the project.
Management says it now plans to undertake multi-element and lead isotope analyses after the bulk of its other analytical work has been completed. It hopes to emulate similar geochemical vectoring used to identify the world-class Cigar and McClean Lake uranium deposits in the Athabasca Basin in Saskatchewan.
Lead isotope and multi-element analysis has been also shown to be an effective tool for locating buried uranium deposits.
It is fantastic that we now have evidence of uranium mineralisation at our high-priority Talus Prospect indicated by anomalous spectrometer readings. Stand-out assays ranging from 311-1301ppm uranium obtained from large pink-white granite talus boulders are highly encouraging. Infini Resources chief executive officer Charles Armstrong
Armstrong said that in addition to soil and biogeochemical samples, the assays would provide the company with important vector data to overlay in the future with unmanned aerial vehicle (UAV) magnetics.
The company’s three priority target areas all lie along the same north-south trend where previous work identified anomalous uranium geochemistry in the range of 337ppm to 865ppm in rock samples. A single historical grab sample within 330m of the highest value rock sample registered an attention-grabbing 2180ppm uranium.
The main Talus prospect trend is about 1600m long, with the other two lower order targets sitting within about 700m off the southern extremity of the main trend.
The word talus implies a form of often coarse erosional detrital cover obscuring in-situ rocks. It usually means it is necessary to employ tools or methods that not only “see through” the loose transported material, but also requires sampling parts of it.
Infini now hopes an airborne magnetic survey by drone will add a further dimension to assist it to home in on potential uranium targets lurking under the talus.
Infini’s 100 per cent-owned Portland Creek project covers an area of 149 square kilometres through ancient Precambrian rocks and includes an extensive regional uranium anomaly identified in the 1970s by a Newfoundland Government stream sediment sampling program. The uranium anomalism includes the 2180 ppm uranium oxide grab sample referred to earlier.
The Newfoundland-Labrador province comprises the island of Newfoundland and the continental region of Labrador and has a combined total size of 405,212sq km. As of January, the combined population of Newfoundland and Labrador was estimated to be 540,552.
Newfoundland, along with its smaller neighbouring islands, is home to about 94 per cent of the province’s population, with more than half residing in the easternmost Avalon Peninsula.
Infini’s current run of 20 analyses exceeding 300ppm uranium obtained from the program points towards a priority target being located nearby.
