Basin Energy Limited (ASX:BSN) (‘Basin’ or the ‘Company’) is pleased to provide an update on its North Millennium Project (the ‘Project’) located in the southeastern part of the world-class Athabasca Basin (Figure 1).
Key Highlights
- 3D inversion of historical geophysical datasets completed1; results support exploration model for unconformity style uranium mineralisation.
- Five-kilometre target corridor defined at North Millennium located along interpreted fault extension, host of Cameco’s Millennium uranium deposit.
- Positive uranium market sentiment continues to build, with U3O8 SPOT price exceeding US$63/Lb.
- Work continues at the Geikie uranium project, with final assay results from maiden drilling and preliminary gravity results expected in September.
- Basin remains fully funded with 5.2 million in cash reserves as at 30 June 2023.
As part of our ongoing assessment of the Project, the Company engaged geophysical experts Computational Geosciences Inc. and Convolutions Geoscience to conduct modern 3D inversion and processing works of the historical geophysical data. Of significance, this work provides further support for the interpretation of a 5-kilometre (‘km’) structural target corridor at North Millennium continuous to the Mother Fault, host of Cameco’s Millennium deposit 7km to the south. The definition of this corridor, known to be the conduit for mineralisation at the world class Millennium Deposit is highly encouraging given that little exploration has ever been conducted on these tenements. Basin will utilise these interpretations as a basis for future exploration, in conjunction with the ongoing works at the Geikie uranium project.
Basin’s Managing Director, Pete Moorhouse, commented“Basin has continued advancing the North Millennium Project through the reprocessing of historic geophysical data. The delineation of disruptions to a basement conductor by an extension to the fault responsible for hosting the world class Millennium uranium deposit provides a tantalising target for unconformity and basement style uranium mineralisation.
Recent discoveries in the area from projects such as West McArthur2 and Moon Lake South3 demonstrate the discovery potential for high-grade uranium mineralisation in this part of the Athabasca Basin. The results from Basin’s study show the exploration prospectivity that North Millennium holds.
Whilst our short-term focus will be the follow up of shallow targets identified through phase one drilling at Geikie, we continue to position the wider portfolio of quality uranium projects to be drill tested.
The uranium sector has had multiple positive catalysts in recent weeks, which is being reflected in the U3O8 spot price. As momentum continues to build, our aim is to position Basin as the preferred ASX listed explorer for high grade uranium discoveries.”

Current Interpretation of the North Millennium Project
The North Millennium project is located in the southeastern portion of the Athabasca Basin, and is situated 7km north of Cameco’s Millennium deposit along the interpreted extension of the host Mother Fault. Basin holds a 40% interest in the project with an option agreement that allows an earn in to 80%.
Minimal historical mineral exploration at the Project occurred between 1979 to 2012, however there are no known historical exploration drill holes. Historical geophysical exploration work was limited to regional scale airborne surveys, and small scale airborne and ground-based electromagnetic surveys with complete or only partial coverage of the Project.
The depth of the unconformity is estimated to be between 700 and 900 metres (‘m’). Z‐Tipper Axis Electromagnetics (“ZTEM”) was the only geophysical method used to date that appears to accurately detect the location of graphitic basement conductors. Additional work consisted of systematic geochemical sampling of lake sediments and sandstone boulders, to measure pathfinder elements concentration and clay mineralogy.

Maiden Drilling Program at Ti-Tree Completed
- 9,086m drilled in 78 holes across six project areas
- Campaign designed to test extensive surface mineralisation identified through soil sampling and rock chip analysis
- Visual observations of copper sulphide mineralisation in quartz veining in multiple holes at depth
- Assays are due back progressively over the coming weeks.
- Exploration and drilling activities to re-commence in Q1 2024
The drilling campaign included 78 holes totalling 9,086m of Reverse Circulation (RC) drilling. The program consisted of discovery drilling only and was designed to confirm historical results and to test near surface mineralisation at depth and along strike, with drilling having been limited to approximately 70m vertical depth.
Holes in the Crawfords, Nic’s Bore and Copper Ridge areas also intersected some visible disseminated mineralisation within quartz veins in the form of pyrite, malachite and chalcopyrite and assay are awaited.
Andrew Reid, Managing Director
“Our maiden drilling campaign following the IPO in May 2023 is now completed and has been a great success. The campaign was designed to test for mineralisation both at near surface and at depth and resulted in visually identifying mineralisation/veining in the majority of drill holes at our Minnie Springs copper-molybdenum-gold project.
Minnie Springs could represent a sizeable porphyry hosted copper deposit with the next step to be the completion of drilling in the remaining 50% of the copper-in-soil anomaly yet to be tested during the next drilling campaign in Q1 2024.”

The second northern-most line at Minnie Springs (Figure 2. MSRC 010 – 012) intersected multiple zones of copper sulphide mineralisation1 co-incident with chlorite-epidote alteration in hole MSRC012, which is characteristic of propylitic alteration commonly seen in in porphyry copper-molybdenum-gold deposits.

EMU Records Gold Assays to 36.1 g/t - Georgetown, Queensland
HIGHLIGHTS*
- Camp Oven Creek area historic surface rock assay results ranging from 12.9 g/t up to 224 g/t gold and 24 g/t to 135 g/t silver from rock samples in broad rhyolite breccia hosted veins in the NW1.
- 15.4 g/t gold assay results recorded from EMU’s first reconnaissance rock samples in the NE Dagworth area, ~19km east from Camp Oven Creek, along Delany Fault extension2.
- 15 historic rock values greater than 31.1 g/t gold (> 1 Ounce) identified from zones in the Camp Oven Creek, 130 Quartz Vein and Quartz 250 Prospects (“new historic information”)3.
- Three historic rock samples in the Quartz 130 prospect returned values ranging from 51 g/t gold up to 73 g/t gold4.
- Limited historic drilling at Rhyolite Breccia/Turtle Arm returned values to 2m at 15.8 g/t Au and 3m at 2.8 g/t Au.( See table 3).
- 86 historic surface rock samples greater than 1 g/t gold with a weighted average of 17.3 g/t within Georgetown EPM 27667 - NW Camp Oven Creek/Turtle Arm quadrant5.
- 2 EMU first reconnaissance rock samples returned 36.1 g/t gold and 25.6 g/t gold respectively from the Sandy Creek prospect just south of Georgetown6.
- Limited historic drilling at Munitions Creek (EPM 27642) returned values to 4m at 2.73 g/t Au and 1m at 10.85 g/t Au. (see table 3).
- EMU’s geological teams currently in field undertaking follow up sampling from these areas.
Commenting on the high gold values historically reported in the project area coupled with EMU’s latest results, EMU’s Chairman Mr Peter Thomas commented:
“It is quite remarkable that the Georgetown tenements and surrounding areas have not been comprehensively subjected to a modern and systematic exploration effort previously. EMU’s initial “first pass” reconnaissance field survey comprised the collection of a limited number of samples from rock outcrop, termite mounds and stream sediments in multiple areas targeted for gold, base metals, lithium and critical minerals. In addition to the recently reported copper, silver and lead values, the gold assay results and historic exploration results support EMU’s view that the project has the potential to deliver world-class discoveries which underpinned its decision to farm into the project”.
Further to the recent announcement7 confirming a substantial high-grade copper and silver system at Fiery Creek and high-grade lead and silver assays results from Snake Creek, EMU reports high grade gold values from rock chip samples collected from a number of prospective areas at Georgetown.
Recently compiled historic gold and base metal drill hole and surface outcrop sampling values from the Georgetown area and from within the three tenements which comprise the project, confirm the outstanding prospectivity of the project.
EMU is currently undertaking a new, limited and targeted follow-up exploration programme with teams in the field over areas not previously sampled to investigate zones which have historically reported high-grade gold and base metal values.

Historical Gold Reported:
Fiery Creek EPM 27667 (Gold + Base Metal Targets)
Based upon significant results that have emerged from the compilation of historic data and the limited field work already completed by EMU, the significant northern portion of the Fiery Creek tenement (EPM 27667) is emerging as a high priority for both precious and base metals. The higher priority targets include structural settings for gold in the Camp Oven Creek, Quartz 130, Quartz 250 and Dagworth Prospect areas, whilst the Fiery Creek prospect within the Yataga Granodiorite demands further attention due to the high-grade outcrop sample assay values for copper and silver.

Significant Number of New LCT Pegmatite Targets Generated from Airborne Lidar at Aqua Property, James Bay – Quebec, Canada
Highlights:
- Airborne LiDAR and high-resolution photography flown across the La Grande Lithium Project.
- Assessment of data from LiDAR and high-resolution photography has generated a total of 123 LCT pegmatite targets across the Aqua Property.
- High-priority targets commence just ~200m to the east of FIN Resources’ significant spodumene showings1, which have returned assayed grades of up to 6.85% Li2O2.
- The La Grande Project is a highly prospective lithium property located along trend from Winsome Resources' (ASX: WR1) Cancet Lithium Project and Patriot Battery Metals (ASX: PMT).
LiDAR has been utilised to measure and map out the variations in slope, aspect and elevation to study landforms. The Company’s exploration team has examined all the variations in slope and elevation to identify and confirm high-priority areas which sit proud of other structures, as these are some of the key geological features expected of Lithium-Caesium-Tantalum (LCT) pegmatites in the region. Once structures have been identified utilising LiDAR, the James Bay Minerals team overlayed these onto high-resolution photos where white outcropping is visible generating key targets. This methodology will also be deployed in the assessment of JBY’s other La Grande Properties and its Troilus Project.
James Bay Executive Director, Andrew Dornan, commented:
“This is another exciting development for the Company with over 120 LCT pegmatite targets identified across our Aqua Property. Given we have the three key geological ingredients for giant LCT lithium- pegmatite deposits – along with FIN Resources’ spodumene discovery on the border of our Property – our confidence in the prospectivity at Aqua and the potential for a significant lithium discovery continues to grow.”
In conjunction with its exploration partner, Breakaway Exploration, JBY is in the process of planning a targeted field program across the Aqua Property focused on field mapping the new LCT pegmatite targets generated from LiDAR and high-resolution photography. This program is planned to commence in the first half of 2024.

LiDAR, an acronym of "light detection and ranging" or "laser imaging, detection and ranging" is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
LiDAR surveys produce a high-resolution topographical image of the surface, allowing detailed desktop exploration of outcropping pegmatites and prospective geological features. The survey will deliver a digital elevation model (DEM) on a 1x1m grid scale with an overlying image of 16cm pixel resolution.
The high-resolution nature of the survey is designed to uncover undiscovered or hidden pegmatites beneath vegetation. Pegmatite outcrops are more resistant to weathering than other lithologies present in the project area and tend to present as topographic highs which can be detected by the high-resolution LiDAR survey. Importantly, this technique has been successfully used in the James Bay region by other explorers and producers in the discovery of lithium-bearing pegmatites.
Background on James Bay Minerals
James Bay has acquired a 100% interest in one of the largest lithium exploration portfolios in the James Bay region, covering an area of 34,572Ha or 346km2. The Joule, Aero and Aqua properties are located in the La Grande sub province along trend from the Corvette deposit, where Patriot Battery Metals (ASX: PMT) recently reported a maiden Inferred Mineral Resource Estimate of 109.2Mt at 1.42% Li2O and 160ppm Ta2O5 (0.40% Li2O cut-off grade).3
The Troilus Project is located further to the south sitting only 5km to the north of Sayona’s Moblan Lithium Project and proximity to Winsome Resources’ Sirmac-Clappier Project.
