Kurundi Main Assay Results Tennant Creek
- TTRC098: 9m @ 1.62g/t Au from 49m including 1m @ 12.75g/t Au from 53m.
Other high-grade results include:
- TTRC103: 3m @ 8.3g/t Au from 35m including 1m @ 16.25/t Au from 36m at the central main zone.
- TTRC092: 5m @ 2.14g/t Au from 38m including 1m @ 6.39g/t Au from 40m at the central main zone.
- TTRC110: 2m @ 5.11g/t Au from 44m including 1m @ 6.33g/t Au from 45m at the northern workings
Also, a possible new style of mineralisation on a porphyry-basalt contact, footwall to the central main mineralized zone has been identified (requires further investigation - see Central Target Area section below) with an intersection of:
- TTRC103: 2m @ 10.93g/t Au from 51m including 1m @ 20.75g/t Au from 51m.
All intersections are stated as down hole widths which are close to true width for the Kurundi Main structure. A second phase of drilling has commenced to test the new southern high-grade zone and continue exploring the other Kurundi Main targets.
Figure 1: Kurundi Main Prospect 2024 drilling (blue dots) with best new results (yellow labels). 2022 drilling shown as black dots.
A total of 28 RC holes for 1,986m have been completed (results listed in Table 2) testing 3 main targets: (1) northern and southern extensions of the Kurundi structure up to 1km from the central main workings, (2) testing the plunge of the central high-grade shoot intersected in 2022 drilling, (3) testing mineralisation deeper under the central main workings.
Central Target Area:
Drilling has confirmed a southerly plunge to the central main high grade gold mineralisation identified in 2022 drilling with TTRC0103 and TTRC092 intersecting high grade gold mineralisation (Figure 2). Also, TTRC103 intersected an unexpected high grade gold zone of mineralisation footwall to the central main zone, on the contact between the basalt host rock and a porphyry intrusive unit (cross section in Figure 3). Due to the lack of structure and alteration being visible in the drill chips the result was initially perceived as a sampling error (2 composite samples from this interval returned anomalous results). However, re-assaying of the pulps followed by resampling at 1m intervals confirmed the presence of gold mineralization and eliminated possible sampling and laboratory errors. This possible new style of mineralisation will be investigated thoroughly with reinterpretation, drill hole relogging, multi element analysis, petrography and drilling to understand possible orientations, further targeting and to eliminate the possibility of down hole contamination of samples during the drilling of TTRC103.
In the Central Target Area KRR’s previous 2022 drilling only tested to a vertical depth of 40m. Four new holes have now been drilled to test a vertical depth of 65m. All holes intersected strong structure, alteration and veining confirming the continuation of the central target zone at depth. TTRC105 intersected a broad zone of veining and alteration and returned 10m @ 0.32g/t Au including 1m @ 0.98g/t Au from 68m with mineralisation open at depth and to the south, shown in the long projection below (Figure 2). The presence of strong veining and shearing at depth across the strike of the central zone is very encouraging for further, deeper drilling.

New results shown in yellow boxes, 2022 results shown in grey boxes, light purple box is for the footwall intersection.
TTRC112 was drilled to test a resistivity anomaly identified by 2023 DDIP survey (KRR ASX: 28 June 2024) however no cause for the resistivity anomaly was identified.

Exploration Program Commences at Virka
Key Highlights
- Historic data review identifies three areas for immediate field investigation
- Initial mapping and reconnaissance sampling underway
- Historic drill core located for relogging, and where possible, sampling:
- Evidence for both significant width and grade mineralisation at the Virka project from drilling which included 1,2
- 9 m at 1,087 ppm U3O8 from 24.5 m in drill hole 81-003
- within 17 m at 707ppm U3O8 from 23 metres depth
- Evidence for both significant width and grade mineralisation at the Virka project from drilling which included 1,2
- No modern systematic exploration undertaken with last significant exploration in 1980’s highlighting district scale potential
Initial work will focus on the assessment of three areas identified through reviewing historic reports. Limited exploration work was documented, but recorded anomalous base metals, silver and uranium. Exploration work at Virka focussed on North-NorthEast orientated structural features, which were interpreted to be a suitable structural conduit for potential mineralisation.
Basin’s Managing Director, Pete Moorhouse, commented:
“The team at Basin are extremely excited to commence work on the recently announced Scandinavian uranium and green energy metals portfolio. Initial review of the available historical data on the Virka project has provided areas for immediate groundwork. We know that the system is prospective for a variety of metals, with the historical drilling indicating favourable thickness of uranium mineralisation.
The team has commenced work immediately at Virka, conscious of the upcoming winter season. Initial work will focus on getting boots on the ground to assess rock outcrops and trace boulder trains. We will move to historic drill core review and additional literature compilation once the weather prohibits further ground activities.”
Virka Project Background 3
The Virka project is strategically positioned in the heart of the Arjeplog-Arvidsjaur shear-hosted uranium district in Sweden, and approximately 37 km southeast of Boliden’s (STO:BOL) Laisvall Pb-Zn-Ag former mine.
Figure 1: Virka initial work locations
Previous drilling activities conducted in the 1980’s across all licenses targeted uranium mineralisation, with diamond drillholes gamma probed and in rare occasions sampled for geochemical analysis3. Additionally, historical regional geological mapping and boulder tracing records unveiled several surface anomalisms in lead, zinc, silver and gold associated with fault structures. Research indicates that these anomalies have not been adequately followed up with results not verified to JORC Code (2012), however using this data and Basin’s interpretations, three areas have been prioritised for immediate field reconnaissance (Figure 1). This program has commenced with the review of these anomalous features that were historically reported in the project area.

Basin Energy
Overview
Basin Energy (ASX:BSN) completed an IPO in October 2022 and is well-positioned as a uranium exploration and development company to take full advantage of the current political and economic environment for the global supply of uranium. The company operates three projects in the world-class Athabasca Basin in Saskatchewan, Canada, known as the world’s leading source of high-grade uranium, currently accounting for approximately 10 percent of global uranium production. The company’s projects are in close proximity to high-grade uranium discoveries and mining operations within the Athabasca Basin.
Interest in uranium has skyrocketed in recent months, driven by the need for lower emissions and stable power generation. Nuclear reactors provide significant power for 32 countries globally, including the US, Canada, China, France, Hungary, Japan and Finland.
Demand has become a key driver of uranium prices, with Sprott Asset Management further enhancing demand by launching two investment vehicles that have already found rapid success: Physical Uranium Trust (TSX:UUN) and Uranium Miners ETF (ARCA:URNM). Combined, existing demand and investment interest create a compelling opportunity for uranium miners and their investors.
In an interview with INN, founding director Peter Bird said, "It's hard to look past the Athabasca Basin as the premium mining jurisdictions for large, high-grade uranium deposits. The region also ranks highly as one of the most stable mining jurisdictions worldwide, which is an increasingly important factor given the current scrutiny on the source of uranium.”
Basin Energy has expanded its portfolio of potential world-class discoveries with the acquisition of projects in Sweden and Finland prospective for multiple commodities including uranium, copper, gold, silver, niobium and rare earth elements. The Scandinavian assets include the Virka project, along with its highly prospective satellite prospects Björkberget and Rävaberget. Exploration activities within the project include drilling across all licenses targeted uranium mineralisation, with diamond drillholes gamma probed and limited geochemical core sampling being completed.
Company Highlights
- Basin Energy is a uranium exploration and development company with three highly prospective projects in the world-renowned Athabasca Basin in Canada, known for being a consistent top three global uranium producer.
- Basin Energy’s board, management team and joint venture partner have direct extensive experience in uranium exploration and development along with comprehensive expertise in corporate financing, investment banking and geology. The company’s highly prospective uranium exploration portfolio comprises:
- The Geikie Project - located on the eastern margin of the Athabasca Basin occupying an extensive land position of 351 square kilometers, showing multiple uranium and uranium pathfinder occurrences, and is prospective for shallow, high-grade mineralization with maiden drilling identifying uranium up to 0.27 percent;
- The North Millennium Project - an interpreted extension of the Mother Fault that hosts Cameco’s Millennium Deposit (104.8 Mlb U3O8 3.76 percent), located just 7 kilometers to the south; and
- The Marshall Project - located only 7 kilometers west of Cameco’s Millennium deposit centered on a strong magnetic and conductive anomaly interpreted as a significant unconformity-type uranium target.
- Basin Energy is committed to sustainable development throughout its operations, aiming to minimize environmental impact from all stages of the exploration and development cycle.
Key Projects
Basin has interest in and is actively exploring three highly prospective properties positioned in the southeast corner and margins of the Athabasca Basin, an area well known for its uranium endowment and pedigree. These are the Geikie (60 percent, North Millenium (40 percent) and Marshall (100 percent) projects.
The project portfolio provides exposure to traditional “unconformity style” exploration, targeting the same mineralisation model as Cameco’s (TSE:CCO) prolific McArthur River mine which hosts 674.9Mlb uranium at 16.9 percent at its North Millenium and Marshall projects, as well as exposure to potentially shallower “basement style” exploration targeting deposits similar to NexGen Energy’s (TSE:NXE) Arrow deposit which hosts 30.61Mlb uranium at 4.6 percent.
Geikie Project
The Geikie Project covers a significant area of 351 square kilometers on the eastern fringe of the Athabasca Basin and is easily accessible from Highway 905, which is located just 10 kilometers to the east. This portion of the Athabasca Basin is deemed perspective for shallow “basement style” mineralisation, but has traditionally been overlooked from much of the previous campaigns of uranium exploration. The discovery of multiple basement-hosted uranium ore bodies in recent years elsewhere in the district has driven a focus on the area.
The project was initially prioritized following a targeting review utilizing historical geophysics. Historical geochemistry confirmed the presence of uranium and suitable host lithologies. Recent nearby high-grade, shallow uranium discoveries by 92 Energy (ASX:92E) and Baselode Energy (TSXV:FIND), further enhance the overall prospectivity of the asset.
Project Highlights:
- Exploration underway: Basin Energy has completed mapping, geochemical sampling, airborne geophysics and maiden drilling. Further drilling is planned for 2024-.
- Shallow targets amenable to rapid exploration: Target horizon sits directly beneath glacial cover, in what was historically an overlooked part of the district.
- Nearby high-grade discoveries: The proximity of recent discoveries creates further confidence in the prospectivity of the project geology, being located adjacent to two recent discoveries:
- 92 Energy’s Gemini discovery 43 meters at 0.6 percent eU3O8 including 6 meters at 2.2 percent U308.
- Baseload Energy’s AKIO discovery was 13.2 meters at 0.55 percent U3O8 including 6.3 meters @ 0.99 percent U3O8.
- Presence of uranium: The maiden drilling program intersected anomalous uranium in four of the eight holes drilled, with assays returning up to 0.27 percent U3O8.
- Extensive scale: Geophysical data, combined with drilling data demonstrates significant scale opportunity with over 30 metres of intense alteration and brecciation intersected in drilling, that can be correlated to regional structural features identified in magnetics. This provides immediate follow up targets.
Since its IPO, the company has completed an extensive campaign of high resolution modern airborne geophysics including magnetics, radiometrics, electromagnetics and gravity gradiometry, as well as initial ground prospecting. These surveys have confirmed the pre-IPO geological interpretation and successfully identified a series of uranium targets.
Basin Energy completed its maiden 2,217-meter drilling program at Geikie in the summer of 2023, the first drilling to occur within the Project area in over 50 years. Drilling successfully identified uranium mineralisation with assays up to 0.27 percent U3O8. Uranium mineralisation is located proximal to two regionally significant structures at Aero Lake and Preston Creek with associated extensive hydrothermal alteration indicative of large uranium mineralising systems. Furthermore, an extensive geochemical pathfinder halo has been identified at Preston Creek, characteristic of uranium mineralising systems seen elsewhere in the district.
The company further expanded the Geikie Project with two additional claims consisting of 11.87 square kilometers, bringing the total Geikie project area to 350.87 square kilometers. The newly staked claims are adjacent to the Preston Creek and Hourglass Lake prospects, where Basin’s maiden exploration drilling is underway.
The company currently owns 60 percent of the Geikie Uranium Project following the fulfillment of expenditure requirements to meet the option payment. Basin has elected to proceed with the option agreement to increase its ownership to up to 80 percent through earn-in stages.
North Millennium Project
North Millennium is located just 7 kilometers north of Cameco’s (NYSE:CCJ) Millennium Deposit, which contains 104.8 million pounds (Mlb) U3O8 at 3.76 percent, and 40 kilometers southwest of their flagship McArthur River Mine hosting 674.9 Mlbs U3O8 at 16.9 percent. Within the property, Basin Energy has identified two high-priority targets along a 5-kilometer corridor for initial priority exploration. The initial target is where an interpreted extension of the Millennium Mother Fault intersects a strong basement conductor.
Project Highlights:
- Favorable geology: The interpreted structural and stratigraphic geology has strong similarities with some of the major uranium deposits within the Athabasca, such as a basement conductor trend disrupted by an interpreted extension of the Millennium Deposit Mother Fault.
- Proximity to known mineralization and recent discoveries:
- Located 7 kilometers north of Cameco’s Millennium deposit
- Drilling to the south of the project, proximal to the Millennium Deposit Mother Fault intersected uranium and uranium pathfinder elements.
- A drill hole on a nearby property completed by joint venture partner CanAlaska (TSXV:CVV) identified high-grade mineralization of 9 meters at 2.4 percent U3O8, further enhancing confidence in the project.
- Thoroughly defined exploration strategy: The company is currently compiling historical data, including completing a 3D inversion of results from an existing historic airborne ZTEM campaign. Exploration work will subsequently consist of:
- Targeted ground geophysics
- Stepwise moving loop time domain electromagnetics
- Potentially DCIP resistivity
- Exploration diamond drilling
- Targeted ground geophysics
Marshall Project
Located in the southeast corner of the Athabasca Basin, the Marshall Project has received limited historic exploration between 1979 and 2009, which included surface geochemistry, electromagnetic surveys and ground geophysics.
The Marshall Project contains a strong magnetic and conductive structure indicative of an unconformity-type uranium target, the asset’s primary target. Recently completed modern 3D inversion and processing works of historical geophysical data identified multiple geophysical anomalies above and below the Athabasca unconformity within the sandstone and basement stratigraphy at the Marshall Project.
Project Highlights:
- Significant geophysical anomalies: Interpretation of historical geophysical data suggests a metasedimentary basin with a graphitic basal unit, cross-cut by a magnetic and conductive NE/SW structure – indicative of a geological setting suitable for high-grade uranium mineralization.
- Proximity to known mineralization and recent discoveries:
- Located 10 kilometers west of Cameco’s Millennium deposit
- A drill hole along strike at the McArthur West project, completed by joint venture partner CanAlaska (TSXV:CVV) identified high-grade mineralization of 9 meters at 2.4 percent U3O8, further enhancing confidence in the project.
- Thoroughly defined exploration strategy: The company is currently compiling historical data, including completing a 3D inversion of results from an existing historic airborne ZTEM campaign.
- Exploration work will subsequently consist of:
- Targeted ground geophysics
- Stepwise moving loop time domain electromagnetics
- Potentially DCIP resistivity
- Exploration diamond drilling as merited
