Infini Resources reveals outstanding uranium results from Portland Creek re-assays

Infini Resources (ASX: I88) has confirmed that re-assaying of 17 soil samples above the laboratory limits of detection has revealed outstanding surface geochemistry at the Portland Creek uranium project in Canada.

The company had reported last week that soil samples from a maiden field campaign exceeded the upper limits of detection and would be subject to re-assay at a different laboratory.

Assay validation

The re-analysis work has revealed that seven of the samples returned grades of more than 3% uranium oxide.

Best among them were 74,997 parts per million, 53,182ppm, 43,512ppm, 39,975ppm, 39,621ppm, 33,961ppm, and 30,777ppm.

They are believed to validate initial soil assays, with all values exceeding the previous detection limit of 11,792ppm uranium oxide.

‘World-class grades’

Infini chief executive officer Charles Armstrong said the soil geochemistry results are among the highest globally recorded on a uranium project.

“These follow-up assays confirm we have encountered world-class grades of uranium in soil samples at Portland Creek,” he said.

“I am not aware of any other explorers that have returned results close to what we are seeing here in our maiden field work program.”

Geochemical studies

Infini has commenced geochemical pathfinder studies to identify any vectors that might point to a primary uranium source proximal to a historic radon gas anomaly.

Around 23 identified anomalies are yet to undergo geochemical testing and are considered to be high-priority targets for urgent follow-up.

Numerous anomaly contours have already indicated the potential for multiple areas of undercover mineralisation to exist within a 3.2-kilometre radiometric corridor.

The company is also awaiting results from processing of an unmanned aerial vehicle drone magnetic survey, which was flown over the Talus prospect in the hope of identifying potential structural controls linked to the anomaly.

Project history

The Portland Creek project covers an area of 149 sq km over a large regional uranium anomaly in Newfoundland.

The anomaly was identified in the 1970s by a government stream sediment sampling program and contains a grab sample that assayed more than 2,180ppm uranium oxide.

The area is believed to have been subject to very limited exploration in recent years.
