Infini Resources has refined its geological model at the Portland Creek uranium project, identifying new high-priority targets for an August 2025 Phase 2 drilling campaign. Despite challenges in Phase 1, the company remains optimistic about unlocking a major discovery in Newfoundland.
- Phase 1 drilling completed six holes totaling 3,150 metres with primary targets untested
- Revised geological model highlights east-west faults as key uranium mineralisation hosts
- Phase 2 drilling planned for August 2025 with minimum 2,500 metres targeting up to 12 sites
- Portland Creek project located in a stable, underexplored uranium province in Newfoundland
- Infini Resources leverages strong technical leadership amid global uranium supply deficit
Phase 1 Drilling, Lessons and Limitations
Infini Resources Limited (ASX, I88) recently held an investor webinar to discuss the outcomes of its initial diamond drilling program at the Portland Creek uranium project in Newfoundland, Canada. The Phase 1 campaign, comprising six drill holes totaling 3,150 metres, faced operational challenges including adverse weather and a restricted drilling window due to local wildlife migration. These factors limited drill penetration and ultimately left the primary geological targets; north-south trending thrust faults; untested.
Despite these setbacks, the data collected has been invaluable in refining the company’s understanding of the project’s structural geology and uranium mineralisation controls.
Evolving Geological Model and New Targets
Infini Resources has significantly revised its exploration model based on structural, geochemical, and geophysical data, including assay results from Phase 1 drill cores. The company now believes that uranium mineralisation is more closely associated with east-west oriented faults, which were previously untested and are interpreted as shallow, near-vertical structures potentially extending beneath high-grade soil anomalies.
This shift in focus has led to the identification of a broader mineralised corridor, with uranium-enriched vein systems hosted within granite formations. These new insights have elevated the priority of east-west faults as targets for the upcoming Phase 2 drilling campaign.
Phase 2 Drilling, A Strategic Step Forward
Scheduled to commence in August 2025, Phase 2 drilling aims to deliver a minimum of 2,500 metres across up to 12 key targets prioritized through integrated geological, geochemical, and geophysical indicators. The program will be led by Rodren Drilling, with Mountain Coast Geological Services providing in-field geological support.
The objectives are clear, to define the geometry and controls of mineralised zones and to generate critical data that could underpin future resource delineation. This next phase is pivotal for testing the continuity, grade, and scale potential of the uranium system at Portland Creek.
Strategic Positioning Amid Global Uranium Dynamics
Portland Creek is situated in Newfoundland’s Humber Tectonic Zone, a stable, tier-1 mining jurisdiction that has historically been underexplored for uranium. The project benefits from proximity to the former Daniel’s Harbour Mine and boasts a large landholding of approximately 149 square kilometres. Early-stage soil geochemistry has revealed high-grade uranium anomalies, including a peak of nearly 7.5% uranium oxide in soils and a massive 3.2-kilometre radiometric anomaly.
Infini Resources’ management emphasizes the company’s strong technical leadership and data-driven exploration philosophy as key differentiators. The firm is positioning itself to capitalize on a tightening global uranium supply-demand balance, which underpins a positive long-term price outlook for the metal.
Looking Ahead
With a clear exploration pathway and a tightly focused strategy, Infini Resources is advancing toward what could be a significant greenfields uranium discovery. The upcoming Phase 2 drilling results will be closely watched by investors eager to see whether the revised geological model translates into tangible mineralisation success.
Bottom Line?
Phase 2 drilling at Portland Creek could be the catalyst that transforms Infini Resources from promising explorer to major uranium player.
Questions in the middle?
- Will Phase 2 drilling confirm the east-west faults as primary uranium mineralisation hosts?
- How might assay results from the upcoming campaign impact resource estimates and project valuation?
- What are the implications of the revised geological model for exploration strategies elsewhere in Newfoundland?
