Mobilisation of Drill Rig and Geological Team to Portland Creek Uranium Project

Infini’s geological team on site conducting mapping and sampling to refine drillhole placement and support agile decision-making.

Drill rig mobilisation to the Portland Creek Uranium Project underway, with drilling scheduled to commence in the coming weeks.

Rodren Drilling engaged for Phase 2 drilling, supported by Coast Mountain Geological for program supervision, core logging, and geological reporting.

Program to test 12 priority targets within a >6km corridor of uranium-in-soil anomalies (up to 74,997 ppm U ₃ O ₈ ), associated with untested East-West faults.

Minimum 2,500m summer drill program developed to efficiently and effectively test the exploration areas, with ability to scale the program based on drilling results.

Infini Resources Ltd (ASX: I88, “Infini” or the “Company”) is pleased to advise that its inhouse geological team has mobilised to the Portland Creek Uranium Project in Newfoundland, Canada.

In addition to drill preparation, Infini’s geological team is undertaking detailed field activities including geological mapping, rock chip sampling and final drill collar siting. These efforts are designed to validate surface anomalies, refine structural interpretations, and ensure optimal drillhole placement and alignment ahead of the upcoming Phase 2 drill program.

Mobilisation of the drill rig to the Portland Creek Uranium Project is also now underway, with transport and logistical arrangements progressing to ensure timely arrival at site. The rig will be prepared to commence drilling shortly after arrival, marking the transition from planning and targeting into active exploration at Portland Creek.

Infini’s Chief Executive Officer, Rohan Bone, said: “The mobilisation of our geological team and drill rig represents a major milestone for Infini. Phase 2 drilling will test the most compelling uranium targets defined to date at Portland Creek, with the potential to deliver a significant uranium discovery in tier-1 uranium jurisdiction. We are entering an exciting phase where each metre drilled has the potential to unlock immense value for shareholders.”

Portland Creek Uranium Project Phase 2 Drill Program Design

The Phase 2 drill program is designed to test multiple priority uranium anomalies, as shown in Figure 1, interpreted to be associated with primary uranium mineralisation hosted in hydrothermal vein systems and structurally controlled fault zones. Targets have been prioritised based on the integration of highresolution soil geochemistry, structural geology interpretation, and reconnaissance fieldwork.

The program has been designed with agility and flexibility in mind, allowing drilling intensity and scope to be scaled in response to results. An initial minimum 2,500m campaign will focus on high-priority targets, with early success guiding deeper and more targeted follow-up drilling. Drilling will focus on intersecting East-West oriented fault zones interpreted to host shear-related uranium mineralisation as a potential source for the project’s exceptionally high uranium-in-soil values, including peak assays of up to 74,997 ppm (~7.5%) U ₃ O ₈ . Indicative hole locations and orientations have been included in Figure 1, subject to further geological mapping, early exploration results and final sighting for suitable drill sites.

About Portland Creek Uranium Project

The Portland Creek Uranium Project spans 149 km² and lies within the Precambrian Long-Range Complex of the Humber Tectonic-Stratigraphic Zone. The geology consists of metaquartzite and a suite of paragneisses, intruded by leucocratic granite, which are believed to have been thrust westward over Paleozoic carbonate-dominant sediments.

The project area covers a large regional uranium anomaly, first identified in the 1970’s through a Newfoundland government lake sediment sampling program. Originally, one uranium showing was recorded in the Newfoundland Mineral Deposit Index, reporting 2,180 ppm U ₃ O ₈ . A compilation of historic and recent exploration data has since delineated a 6 km zone of anomalous uranium and radon gas in lake sediments, soils and in an airborne radiometric survey. This anomaly closely follows a prominent fault scarp, marking the edge of a granitic plateau interpreted as a deep-seated fault.

Since listing, the Company has verified historical uranium anomalies and completed a soil sampling grid over the Falls Lake Prospect (formerly the Talus Prospect). This work defined a ~800 m x 100 m highgrade uranium anomaly, with a peak result of 74,997 ppm U ₃ O ₈ . This anomaly is located down-ice and west of a 1.5 km radiometric anomaly. Additionally, Infini has identified a southern 500 m-wide cluster of high-grade soil samples, which includes a peak of 1,500 ppm U ₃ O ₈ and lies 1.5 km from the recently completed Phase 1 drill program.
