Infini zeros in on uranium-rich fault corridor in Canada

Infini Resources is charging ahead with its uranium exploration ambitions in Canada after today revealing a refined targeting model for its Portland Creek project in Newfoundland that integrates multiple high-priority geophysical, geochemical and structural datasets to home in on a potential discovery.
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.
