Australian Rare Earths Limited (ASX: AR3) is pleased to announce highly encouraging results from its ongoing exploration drilling program at the Overland Uranium Project.
Highlights:
- New shallow Uranium occurrence identified: Drill hole OV047 encountered a 6 meter interval of carbonate-cemented sediments from 27 meters, with anomalous gamma and pXRF uranium readings.
- Potential for the presence of an additional uranium model: Hole OVO47 demonstrates potential for near-surface, calcrete-hosted mineralisation (see Figure 1) - similar to uranium deposits1 mined in Namibia2 - in addition to AR3’s initial palaeochannel hosted ISR amenable uranium deposit targets.
- Accelerated follow-up drilling: Drilling program will re-commence in the week beginning 10 March 2025 to follow up the shallow uranium occurrence intersected in hole OV047.
- Rapid assay and minerology analysis: Samples generated from hole OV047 are being prioritised for assay and mineralogical determinations.
- Palaeovalley extension confirmed with multiple Uranium targets: Drilling has successfully defined the southern extension of a key palaeovalley within the southern portion of EL7001 and extending into EL6678 (See Figure 2).

AR3 Managing Director and CEO, Travis Beinke, said:
“The intersection of a shallow uranium occurrence in OV047 is a significant step forward in our exploration program at Overland. The identification of shallow mineralisation, coupled with the confirmation of the palaeovalley's southern extension, underscores and reinforces the - potential of this project.
Our systematic approach to exploration and targeted drilling, continues to deliver results. We are excited to accelerate our follow up drilling to further delineate the extent of this new uranium occurrence and test the numerous high-priority targets we have identified. We look forward to reporting further results as we continue our drilling program through to the end of April."

In relation to the disclosure of pXRF results, the Company cautions that estimates of uranium elemental abundance from pXRF results should not be considered a proxy for quantitative analysis of a laboratory assay result. Assay results are required to determine the actual widths and grade of the mineralisation. The company uses an Olympus Vanta M Series portable X-ray Fluorescence (pXRF) analyzer to screen Air Core drilling samples for mineralization prior to submitting samples to a commercial laboratory for assay. This provides an initial understanding of the mineralization distribution before sampling, ensuring submitted samples are representative of the targeted mineralization. While pXRF confirms the presence of mineralization, it does not accurately determine elemental concentrations due to limitations such as a small analysis window, uneven distribution, shallow penetration depth, and irregular surfaces. The pXRF results are indicative and the pXRF readings are subject to confirmation by chemical analysis from an independent laboratory.
The 2025 program, which began 30 January 2025, has focused on mapping the newly defined palaeovalley (refer ASX release 21 January 2025) further south within EL7001 and onto the Sheer Gold Farm-In tenure, EL66783. A total of 22 drillholes has been completed, totaling 3,010 meters, illustrated in Figure 2.
Target 1 of EL6678, drillhole OV047 has intersected a 6 meter interval containing anomalous gamma and pXRF Uranium (U) responses. Gamma responses peaked at 741 counts per second (cps), with maximum pXRF uranium response of 105ppm U. This surficial uranium occurrence is similar to uranium mineralisation found in Namibia’s surficial uranium deposits, like Paladin Energy’s Langer Heinrich Mine. Similar calcrete-hosted deposits are also found in Western Australia4 at Cameco Corporation’s Yeelirrie deposit and Toro Energy’s Wiluna project.
The identification of another potential uranium occurrence model at Overland highlights the region’s fertility, where uranium in solution enters the basin and is captured at various geochemical interfaces within the sedimentary sequences. Drillhole OV047 shows anomalous uranium responses over a 6 meter interval from 27 meters and displayed the highest gamma response yet seen at the base of oxidation interface with reduced sediments. These findings suggest potential for both deeper palaeochannel hosted, in-situ recoverable (ISR) deposits and shallow surficial deposits in this setting.

Terra Clean Energy Corp. Completes First Three Drill Holes on Fraser Lakes Uranium Deposit with Encouraging Initial Results
TERRA CLEAN ENERGY CORP. (“Terra” or the “Company”) (CSE: TCEC, OTCQB: TCEFF, FSE: 9O0), is pleased to announce the completion of the first three drill holes at the South Falcon East Uranium Project (the “Property”) which hosts the Fraser Lakes B Uranium Deposit. Drilling will continue throughout March and is expected to complete over 2000 meters (m) of drilling.
The South Falcon East Project lies 18 km outside the edge of the Athabasca Basin, approximately 50 km east of the Key Lake uranium mill and former mine (Figure 1). The Company entered into an option agreement with Skyharbour Resources Ltd. (“Skyharbour”) in October of 2022 whereby the company can earn up to a 75% interest in the Property.
The Company is currently conducting a 2000-2200 m helicopter supported drill program at the Property. Three diamond drill holes have been completed on the Fraser Lakes B Uranium Deposit, for a total of 802 m. A fourth hole in progress. (Figure 3)
“We are extremely encouraged by the results of the first three drill holes as we continue to see minerlization in each of the first three holes as well as what we believe to be an expansion of the deposit to the North. As stated below, Hole SF063 returned a continuous mineralized zone of pegmatities from 173 meters to 224 meters with some decent grades.” Based on the initial results from Hole SF063 we have decided to reorganize the remaining meters of this program to focus on further defining this new area of interest and chasing clay alteration not yet seen on the property to date, with hopes of finding a high grade unconformity uranium deposit.” said Greg Cameron CEO of the Company.
Hole SF063 was planned to examine an interpreted cross fault offsetting the mineralization and geology on the east end of the Fraser Lakes B Uranium Deposit. This hole was drilled to a depth of 393 meters and intersected multiple structures and a 51 m wide interval of mineralized granitic pegmatites and zones within altered and graphitic pelitic gneiss. Highlights include:
- 0.03% eU over 12.0 m from 173.55 to 185.55 m,
including 0.06% eU3O8 over 0.7 m from 180.35 to 181.05 m
- 0.03% eU over 3.0 m from 213.65 to 216.65 m,
including 0.07% eU3O8 over 0.5 m from 215.95 to 216.45 m
The first structure intersected from 18 m to 47.5m contained zones of intense clay alteration typically found in relation to unconformity uranium deposits. The presence of this alteration is a good indication that hydrothermal fluids suitable for deposition of higher-grade uranium deposits moved through the rocks. The second structure from 306 to 315 m is a brecciated pelitic gneiss situated between two intervals of Archean gneiss. This structure is interpreted to be responsible for the geological offset being targeted. This will assist in updating the target model in this area. The intersections of a clay altered structure and a thick sequence of mineralized pegmatites and pelitic gneiss have expanded the mineralization and improved the prospectivity on the east end of the Fraser Lakes B Uranium Deposit.
”The results from the drilling so far are very encouraging,” commented Trevor Perkins, Vice President of Exploration for Terra Clean Energy Corp. “The first two holes have shown that the deposit is still open down dip to the north and northwest. Hole SF0063 has shown that there is significant potential for upgrading the deposit on the east end. We are excited to see where this can lead”, continued Mr. Perkins.
Drilling is continuing with one hole in progress in the T-Bone lake area to examine the conductive package and alteration intersected in the area in historical drilling. Pad preparation is underway to return to the area around SF0063 and follow up on the clay alteration and pegmatites. Efforts will be made to follow the alteration and pegmatites to where they intersect, as this should be an area of fluid pooling and upgrading of mineralization within the deposit.
Hole SF061 was planned to test for a down dip extension of mineralization intersected in hole FP-15-05 and was drilled to a depth of 209 m. Drilling intersected a 35 m interval containing multiple mineralized granitic pegmatites and zones within altered and graphitic pelitic gneiss. The most notable zone returned an equivalent grade of 0.02% eU3O8 over 2.2 m from 150.25 to 152.45 m, including 0.05% eU3O8 over 0.6 m from 151.65 to 152.25 m.
Historical diamond drill hole FP-15-05 was drilled by Skyharbour in 2015 and returned multiple zones of mineralization over a 14m interval, including 6m of .10% U308 (including a 2m of 0.165% U3O8 (from 135m) and 2.5m of 0.172% U3O8 (from 145m).
Hole SF062 was planned to test for an along strike extension of mineralization intersected in holes FP-15-05 and SF0061, and was drilled to a depth of 200 m. Drilling intersected a 21 m interval containing multiple mineralized granitic pegmatites and zones within altered and graphitic pelitic gneiss. The most notable zone returned an equivalent grade of 0.03% eU3O8 over 2.2 m from 141.75 to 144.15 m, including 0.05% eU3O8 over 0.4 m from 143.15 to 143.55 m.
While both of these holes extended the mineralization down dip and along strike to the north and northwest, they did not intersect the higher grades encountered in hole FP-15-05. This is due to the potential variability within the pegmatite swarm. As long as the mineralized pegmatites are present, higher grades will be encountered within the overall mineralized zone.

Samples of the mineralized intervals within the drill core have been collected and shipped for analysis at the Geoanalytical Laboratory at the Saskatchewan Research Council in Saskatoon, Saskatchewan. The Company will provide more detailed results once geochemical analysis of the collected core samples is completed, reviewed and confirmed.
QA/QC, Radiometric Equivalent Grades and Spectrometer Readings:
All drill intervals above are downhole length and sampling procedures and QA/QC protocols for geochemical results as well as a description of downhole gamma probe grade calculations and protocols are below. All drill core samples are shipped to the Saskatchewan Research Council Geoanalytical Laboratories (“SRC”) in Saskatoon, Saskatchewan under the care of Terra personnel for preparation, processing, and multi-element analysis by ICP-MS and ICP-OES using total (HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion, and U3O8 wt% assay by ICP-OES using higher grade standards. Assay samples are chosen based on visual inspection, downhole probing radiometric equivalent uranium grades and scintillometer (Radiation Solutions RS-125) peaks. Assay sample intervals comprise 0.5 to 1.0 metre continuous half-core split samples over the mineralized interval. These samples may also be selected for density determination using the lost wax method. With all assay samples, one half of the split sample is retained and the other sent to the SRC for analysis. The SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats are inserted into the sample stream at regular intervals by Terra and the SRC in accordance with Terra’s quality assurance/quality control (QA/QC) procedures. Geochemical assay data are subject to verification procedures by qualified persons employed by Terra prior to disclosure.
During active exploration programs drillholes are radiometrically logged using calibrated downhole Mount Sopris 4OTGU or 2GHF probes of varying sensitivities which collect continuous readings along the length of the drillhole. Preliminary radiometric equivalent uranium grades (“eU3O8”) are then calculated from the downhole radiometric results. The probe is calibrated using an algorithm calculated from the calibration of the probe at the Saskatchewan Research Council facility in Saskatoon and from the comparison of probe results against geochemical analyses. In the case where core recovery within a mineralized intersection is poor or non-existent, radiometric grades are considered to be more representative of the mineralized intersection and may be reported in the place of assay grades. Radiometric equivalent probe results are subject to verification procedures by qualified persons employed by Terra prior to disclosure.
