Infini zeros in on uranium-rich fault corridor in Canada
The company says its enhanced model stems from processing downhole acoustic and optical televiewer data collected from six drill holes at the site earlier this year. Infini believes the new datasets support the interpretation of steeply dipping structurally controlled uranium mineralisation beneath the Falls Lake prospect talus slope – the focal point of the Portland Creek campaign.
Management says all six completed diamond drill holes intercepted multiple brecciated shear zones up to 75 metres wide associated with significant hydrothermal alteration and vein-hosted uranium mineralisation. The updated targeting model incorporates pXRF readings, downhole data, UAV magnetic analysis, structural interpretation and alteration mapping to build a comprehensive exploration vector framework.
It represents the next major step in the company's quest to discover a potentially economic uranium deposit along the Trident Lake fault corridor – a 6-kilometre-long zone of anomalous uranium identified in the 1970s but never properly drill tested.
Encouraging pXRF results from the maiden campaign included standout intercepts of 9391 parts per million (ppm) uranium trioxide, including 4694ppm and 4328ppm from within a narrow 1m interval in one hole. Results of 1878ppm and 1019ppm, as well as 1220ppm were recorded in two further holes, respectively.
Portable XRF readings are considered indicative only and are pending confirmation from laboratory assays. However, they remain an important early-stage guide to uranium prospectivity in the company's frontier exploration terrain.
The company's geological team is now back on site to complete detailed surface mapping and sampling to better delineate the fault and alteration systems identified through the first round of drilling. That work is expected to further refine the company's targeting strategy ahead of a second phase of drilling, anticipated to begin about August 15, after the end of the wildlife season.
The Falls Lake area is believed to contain a shear-hosted (albitite-type) uranium system of the same geological style that produced major uranium deposits in other parts of the world. The target is interpreted to sit beneath talus material shed from an elevated scarp and is not exposed at surface, which may have contributed to its historical under-exploration.
The campaign at Portland Creek is also being bolstered by the appointment of Infini's new exploration manager Nick Mitchell, who is on site to oversee field operations. The company says Mitchell's appointment reflects the importance it places on the project as its flagship Canadian uranium asset.
Infini's initial 2025 drilling campaign was partly funded by a $3.4 million capital raising completed in February at a 27.8 per cent premium to the then market price. Importantly, the flow-through funding, secured under Canadian tax law, ensures capital raised will be directed solely to exploration activity.
In addition to Portland Creek, Infini has been steadily expanding its broader Canadian uranium portfolio with the full acquisition of the Reynolds and Boulding Lake projects in Saskatchewan's renowned Athabasca Basin, which is home to the world's highest-grade uranium deposits.
Reynolds and Boulding Lake span a combined 931 square kilometres and lie within 100km of the famous McArthur River and Eagle Point uranium mines. Initial work is targeting unconformity-style deposits, with airborne geophysics, sampling and mapping to kick off later this year.
The acquisitions are considered a natural complement to Portland Creek, with both assets giving the company significant exposure to premier uranium jurisdictions in North America.
Infini says its strategic objective is to build a portfolio of high-impact uranium projects capable of supporting the clean energy transition through the discovery and development of new supply sources. With uranium prices showing long-term strength and nuclear power regaining its global prominence, the timing could hardly be better.

Trump ramps up trade war with Canada over Palestine as deadline looms
US President Donald Trump intensified his trade war with Canada a day before his August 1 deadline for a tariff agreement, saying it will be 'very hard' to make a deal with Canada after it gave its support to Palestinian statehood. Trump is set to impose a 35 per cent tariff on all Canadian goods not covered by the US-Mexico-Canada trade agreement if the two countries do not reach an agreement by the deadline. 'Wow! Canada has just announced that it is backing statehood for Palestine. That will make it very hard for us to make a Trade Deal with them,' Trump said on Truth Social. Canadian Prime Minister Mark Carney previously said tariff negotiations with Washington had been constructive, but the talks may not conclude by the deadline. Talks between the two countries were at an intense phase, he added, but a deal that would remove all US tariffs was unlikely. Meanwhile, the global tariff regime is facing a crucial court challenge. From 2am Friday (AEST), eleven judges in Washington DC will hear arguments from the Trump administration and two small businesses who say that many of his import duties are illegal. The businesses sued the president over his enacting the International Emergency Economic Powers Act of 1977. All of the White House's tariffs on major trading partners have been enacted under that law. Canada is the second-largest US trading partner after Mexico, and the largest buyer of US exports. It bought $US350 billion ($540b) of US goods last year and exported $US413b to the US, according to US Census Bureau data. Canada is also the top supplier of steel and aluminium to the United States, and faces tariffs on both metals as well as on vehicle exports. In June, Carney's government scrapped a planned digital services tax targeting US technology firms after Trump abruptly called off trade talks saying the tax was a 'blatant attack'. Carney followed France and Britain as he said on Wednesday that his country was planning to recognise the State of Palestine at a meeting of the United Nations in September. In announcing the decision, Carney spoke of the reality on the ground, including starvation in Gaza . 'Canada condemns the fact that the Israeli government has allowed a catastrophe to unfold in Gaza,' he said. Israel and the United States, Israel's closest ally, both rejected Carney's comments. Carney's office did not immediately respond to a request for comment on Trump's post.
