Uranium Grades exceeding 4245ppm  U₃O₈ in South West Corner Trench Assays

Gladiator Resources Ltd (ASX: GLA) (Gladiator or the Company) is pleased to announce assay results for trenches at the SWC Target within its 724km2 Mkuju Uranium Project. The trenches have high-grade uranium mineralisation and support GLA’s model of gently dipping uraniferous sandstone layers with considerable strike extent. The next step is to drill-test the potential depth extension of these layers. No drilling, other than shallow auger holes, has been previously completed at the two identified zones which have a combined ‘strike-length’ of ~3km. The results affirm the Company’s view that there is potential for a significant sandstone-hosted uranium deposit at SWC, which is within the same geological basin as the Mantra/Uranium One’s world class “Nyota” deposit which has a Measured and Indicated MRE of 187 Mt at 306ppm U₃O₈ containing 124.6 Mlbs U₃O₈.

  • Assay results for SWC target trenches received and confirm high-grade uranium in 4 of the 5 trenches and one of the mineralised layers is interpreted to be at least 6 m thick.
  • Results include intervals above the upper detection limit of analytical method (4245ppm U₃O₈). These samples are being re-analysed by another method that has higher detection limits.
  • Results indicate gently dipping layers of mineralised sandstone. The exposed part of the layer in Trench 4 layer has an average grade of 1727 ppm U₃O₈ and includes one sample above the upper detection limit of analytical method (4245ppm U₃O₈). This is the only trench on the north side of the target.
  • The recentradiometric data and the trench and auger data define a combined ‘strikelength’ of the north and south zones of approximately 3 km.
  • The excellent work by the geology team means that SWC is now drill-ready. No drilling other than shallow auger holes (in 2008) has been carried out at Gladiator’s targets.
  • The trenches support the 2008 augerresults which included 8m @ 1,273ppm U₃O₈ from surface, including 2m@ 3,825ppm.

Trenching Program and results

Gladiator completed 5 trenches at the SWC target in October 2023; four at the ‘South Limb’ zone and a single trench at the ‘Nouth Limb’ zone (Figure 1). A total of 454 metres of trenching was completed and the trenches were between 3.0 and 3.9 metres deep. Sampling was taken from vertical channels at 4.0 metre intervals along one sidewall of each trench. Table 1 provides the highest-grade vertical intervals from each trench and Figures 2 and 3 illustrate the results more comprehensively. Where average grades are reported these were calculated by length-weight averaging of the sample grades within each layer.

Of particular interest is trench 4 at the ‘North Limb’ zone:

  • Gently northward dipping coarse-grained arkose sandstone layer with visible high-grade uranium (Figure 4).
  • In the trench the upper part of the layer (~2 m true thickness) has an average grade of 1935ppm U3O8. The material lower in the trench has an average grade of 676ppm U3O8.
  • A 1.4 m sample from this layer has over 4245 ppm which is the upper detection limit for the pressed powder analytical method and will be re-analysed using the fusion method to obtain the actual value.
  • Based on a nearby 2008 auger hole (MRSA6, 30 m to the east) the layer in the trench may be the upper part of a layer at least 6 m in thickness - the auger hole ended in mineralisation (510 ppm U3O8) at 7 metres depth.
  • This trench is the only one at the ‘North Limb’ zone of SWC. It would have been ideal to have more trenching completed but the onset of the wet season prevented further work. It is clear that drilling is needed to follow the layer ‘down-dip’.

Trench 2 and 5 at the ‘South Limb’ zone:

  • These trenches are 650 m apart and both intersect what may be two southward dipping mineralised layers approximately 4m apart, hosted in coarse-grained sandstone.
  • In Trench 5 the first (southernmost) layer has an average grade of 2042ppm U3O8 and has an approximate (true) thickness of 3m. Within this are 2 samples with over 4245 ppm, the upper detection limit for the analytical method. In Trench 2 the same layer has an average grade of 708ppm U3O8 and a similar average (true) thickness.
  • The second and northernmost mineralised layer in Trench 5 has average grade of 1518ppm U3O8 and has an approximate (true) thickness of 3m. The same layer in Trench 2 has an average grade of 2163ppm U3O8 and is approximately 1.0 m thick

The word uranium with a green arrow pointing up.

Uranium Stocks Surge as Kazakhstan Raises Mineral Extraction Tax

Kazakhstan's announcement of a significant increase in the Mineral Extraction Tax (MET) for uranium sent uranium stocks trending higher on July 10 as concerns of a potential supply disruption grew due to Kazakhstan's position as the world’s largest uranium-producing country.

The new tax rate changes will come in two waves. The first, effective January 1, 2025, will impose an initial hike from the current 6 percent to 9 percent.

Starting in 2026, they will take on a more complex and differentiated rate structure, structured to vary based on production volumes and the price of natural uranium concentrate (U3O8).

For production volumes up to 500 metric tons, the rate will be 4 percent, increasing incrementally to a maximum of 18 percent for volumes exceeding 4,000 metric tons.

Wyoming pinned with a red tack on a map.

Indigo Acquires Hot Uranium Property in Wyoming

Indigo Exploration (TSXV:IXI) has announced the acquisition of a 100 percent interest in the Hot property, a uranium project located in the Shirley Basin of Wyoming, US.

“Gaining 100 percent interest in a project of this calibre, located in a key uranium district next to past production and some of the preeminent US-focused uranium producers and developers, and with extensive historical drill results, is an exciting new development for the Company,” Indigo’s President and CEO Paul Cowley commented in the company's press release.

The Hot property covers 71 unpatented mineral claims over a 5.75 square kilometer area and has been the site of extensive historical exploration since the 1960s.

Wyoming is historically the largest uranium-producing state in the US and has the greatest uranium ore reserves. The Shirley Basin produced over 51 million pounds of U3O8 from 1960 to 1992 at an average grade of 0.22 percent U3O8. However, depressed uranium prices in the late 1900s led to many mines in the region shuttering. The resurgence in uranium prices in recent years has brought interest back to the region as companies look to restart operations, develop uranium deposits or make new discoveries.

Global Uranium Mining Market Expected to Reach $11.38 Billion By 2030 as Dependency on Nuclear Power Increases

FinancialNewsMedia.com News Commentary - In line with the rise of nuclear energy since the 1950's, uranium has become a pivotal commodity. This is especially true for countries that are highly dependent on nuclear energy to fulfill their domestic energy needs. According to a report from Statista, that the leading consumers of uranium worldwide are the countries with the highest share of nuclear energy: the United States, China, and France. The U.S. used nearly 18,300 metric tons of uranium in 2020. That was more than twice as much as France, which ranked third. Although there are global tendencies towards alternative energies, the worldwide nuclear energy consumption has remained consistent over the past decade. This suggests that uranium will likely continue to be an important commodity for decades to come. A report from GlobalData added that Uranium production is expected to grow marginally at a CAGR of more than 4% from 2024 to 2030 and that the countries holding significant uranium reserves are Australia, Kazakhstan, Canada, Russia, and Namibia among others. In 2023, Australia had the largest share followed by Kazakhstan. In terms of uranium production, Kazakhstan led the market followed by Canada. Active Mining Companies in the news includes: Indigo Exploration Inc. (OTCQB: IXIXF) (TSX-V: IXI), Ur-Energy Inc. (NYSE American: URG) (TSX: URE), Cameco Corporation (NYSE: CCJ) (TSX: CCO), Denison Mines Corp. (NYSE American: DNN), Uranium Energy Corp (NYSE American: UEC).
