Aura Energy Limited (ASX:AEE, AIM:AURA) is pleased to announce that the Resource Upgrade program undertaken in 2022 has increased the Measured and Indicated (M&I) Resources at the Tiris Project (“Tiris or the “Project”) from 19.5 Mlbs to 29.6 Mlbs, 62.2Mt at 216ppm U3O8 at a 100ppm cut-off.
KEY POINTS:
- 52% increase in Measured and Indicated Resources to 29.6 Mlbs U3O8, 62.1Mt at 216 ppm U3O8 at a 100ppm grade cut-off.
- Global Mineral Resource Estimate (MRE) of 58.9 Mlbs U3O8, 113Mt at 236 ppm U3O8 at a 100ppm grade cut-off.
- Near-term exploration targets identified to further grow the Tiris resource.
- Tiris Reserves estimate with the updated expanded Feasibility imminent
The significance of the Resource upgrade is that it enables Aura to update the 2019 Tiris Definitive Feasibility Study (DFS)1project work, assessing the potential to increase the production rate based on the increased M&I resource. This work is expected to be released before the end of Q1 2023.
Aura’s Tiris Project differs from other near-term projects in that the carnotite is mostly ultrafine, micron scale in grain size enabling the separation of the uranium without crushing and grinding as demonstrated in the 2019 DFS1. In the DFS1 production averaged 800,000 lbs U3O8 per year with a capital cost of USD 74.8 million and C1 costs of USD 25.43/lb U3O8. Aura is confident that our existing fast-to-market development strategy will be accentuated in the updated DFS as a result of the economies of scale on the capital and operating costs using a modular expansion of the Tiris Project.
Commenting on the increased MRE, Aura Energy Managing Director Dave Woodall said:
“The significant increase of our M&I resources confirms our confidence that the Tiris province which we believe has great expansion potential. Our immediate focus is now to work with our Mauritanian stakeholders, offtake providers, investors and financing partners to progress towards a decision to Mine in Q3 CY2023, a target construction timeline of Q4 CY2023, and first production expected in late 2024 or early 2025.
“Our exploration success is creating a strong platform for growth for Aura’s shareholders and our Mauritanian partners, and an exciting new zero-carbon energy source for an increasingly energy-hungry world.”

Major technology companies including Amazon, Google and Meta have committed to supporting the goal of tripling global nuclear capacity by 2050, further validating the sector's growth trajectory.Greenvale's portfolio includes the promising Oasis uranium project with high-grade intercepts up to 0.72 percent U3O8, four uranium projects across the Northern Territory, the Alpha Torbanite project, and the Millungera geothermal project in Queensland.
Key Projects
Uranium Projects
Oasis Project (Queensland)
The Oasis project is an advanced-exploration Project, featuring exceptional high-grade intercepts up to 0.72 percent U3O8 (15.8 lbs/ton). Originally discovered in 1973, the deposit has seen sporadic exploration including significant work by Esso in 1978/79. The project area contains extensive radiometric anomalies with multiple faults and fractures controlling the distribution of uranium mineralization.
Greenvale has developed a comprehensive work program for Oasis, beginning with regional geological field prospecting and reconnaissance, followed geophysical and geochemical surveys across the Oasis prospect and regional areas. These preliminary works are key to develop and refine targets for Greenvale’s planned maiden drill program at Oasis.
Northern Territory Uranium Projects
Greenvale has four strategic uranium projects in the Northern Territory: Jindare project in Douglas River, Henbury, Elkedra and Tobermorey. These projects target sandstone hosted and unconformity style uranium mineralization, with particular focus on areas where uranium-bearing waters may interact with hydrocarbons, creating optimal conditions for uranium deposition. The geology of these assets is similar to uranium deposits in Kazakhstan, the world’s leading producer of uranium.
The Henbury project is particularly noteworthy, located on the edge of the Amadeus Basin, a major hydrocarbon basin in the Northern Territory. Following research from Geoscience Australia, Greenvale is targeting areas at the margins of hydrocarbon cap-rocks near active structures, which represent prime locations for uranium mineralization.
Alpha Torbanite Project
The Alpha Torbanite Project represents a unique opportunity to supply Australia's infrastructure sector with domestically-produced bitumen. The project features a substantial 28 Mt inferred resource of torbanite and cannel coal, positioning Greenvale to potentially capture a significant share of Australia's annual bitumen consumption (currently assessed as approximately 1 Mt all serviced through material imported from overseas).
Torbanite is a rare type of oil shale containing exceptionally high concentrations of algal-derived hydrocarbons that can be processed to produce high-quality bitumen products. This natural conversion capability makes torbanite deposits like Alpha particularly valuable for infrastructure applications as they can yield bitumen substitutes with properties comparable to petroleum-derived products.
To date, the company has been able to secure over $3 million in non-dilutive R&D grant funding to support project development.. The Company's test program continues to show improved results, with test program 7 planned to produce a bulk sample for certification. Certification will underpin the progression of feasibility studies that will define the full economic potential of the project.
Queensland Geothermal Project
Greenvale's Millungera Basin geothermal project targets one of Australia's most prospective areas for geothermal energy. The basin contains the hottest rock formations in Queensland, with a total identified stored thermal energy potential exceeding 611,000 PJ (at 90 percent probability). Technical reports indicate the potential for an estimated annual electricity generation of 29,621 GWh from inferred resource areas, with capacity to produce 3.4 GW continuously.

Blue Sky Uranium
Investor Insight
Blue Sky Uranium offers investors an entry into the uranium market via its strategic position in Argentina's uranium sector, significant resource base, favorable project economics, and strong joint venture partnership providing a clear path to potential production without dilutive financing requirements.
Company Overview
Blue Sky Uranium (TSV:BSK,OTC:BKUCF) is emerging as a frontrunner in uranium exploration and development in Argentina. As a member of the Grosso Group, which has pioneered resource exploration in Argentina since 1993 and been involved in four major mineral discoveries, Blue Sky benefits from deep regional expertise and established relationships.
The company's flagship Amarillo Grande Project represents an in-house discovery of Argentina's newest uranium-vanadium district. This district-scale project spans 145 kilometers and encompasses more than 300,000 hectares of mineral rights in Rio Negro Province. With the largest NI 43-101 compliant uranium resource in Argentina at its Ivana deposit, Blue Sky is strategically positioned to potentially become the first domestic supplier to Argentina's growing nuclear industry, which currently imports all its uranium fuel.
As global uranium markets experience their strongest fundamentals in over a decade, Blue Sky is positioned to leverage this growing trend. Global demand for uranium is projected to outpace supply, with a significant supply deficit forecast in the coming years. This supply-demand imbalance is being driven by the re-emergence of nuclear energy as a critical component in the global transition to cleaner energy sources. Concerns about energy security, particularly in Europe, combined with nuclear energy's ability to provide reliable baseload power with zero carbon emissions, have led to policy shifts favoring nuclear energy expansion in many countries. This renaissance is reflected in uranium prices, which have surged from lows of around $20/lb in recent years to more than $80/lb in 2024, with contracts and spot prices showing sustained strength.
Beyond Amarillo Grande, Blue Sky is expanding its portfolio with projects in the Neuquen Basin targeting uranium deposits amenable to in-situ recovery (ISR) methods, further diversifying its growth potential in line with these positive market trends.

Key Projects
Amarillo Grande Project (Flagship)
The Amarillo Grande project, located in Rio Negro Province, represents Blue Sky's cornerstone asset and a district-scale opportunity in Argentina's uranium sector. Spanning 145 kilometers and covering approximately 300,000 hectares, this project encompasses three main property areas: Ivana, Anit and Santa Barbara. Each area contributes to the project's significant potential as an emerging uranium-vanadium district.
Ivana
The Ivana property hosts the project's flagship Ivana deposit, the crown jewel of Blue Sky's portfolio and the largest NI 43-101-compliant uranium resource in Argentina. Located in the southern portion of the Amarillo Grande project, the deposit features a 5-kilometer-long arcuate mineralized corridor with a high-grade core that ranges from 200 to over 500 meters in width and reaches up to 23 meters in thickness.
The deposit's resource estimate, updated in February 2024, includes 19.7 million tons (Mt) of indicated resources grading 333 parts per million (ppm) uranium and 105 ppm vanadium, containing approximately 17 million pounds (Mlbs) of U3O8 and 8.1 Mlbs of V2O5. Additionally, the deposit hosts 5.6 Mt of inferred resources grading 262 ppm uranium and 109 ppm vanadium, containing approximately 3.8 Mlbs of U3O8 and 2.4 Mlbs of V2O5. Importantly, about 80 percent of the current resource is classified in the higher-confidence indicated category, providing a solid foundation for economic studies and development planning.
The Ivana deposit’s near-surface mineralization makes it ideal for low-cost mining, as no drilling, blasting or crushing would be required for resource extraction. The deposit's location in a semi-desert region with low population density, minimal environmental risks, and good accessibility further enhances its development potential.
The 2024 preliminary economic assessment (PEA) for the Ivana deposit demonstrates compelling returns, with an after-tax NPV (8 percent discount) of US$227.7 million and an IRR of 38.9 percent at a base case uranium price of US$75/lb. At a spot case price of US$105/lb, these figures improve dramatically to an NPV of US$418.3 million and an IRR of 57 percent. The initial capital cost of US$159.7 million (including contingency) is modest relative to the project's scale, with a payback period of just 1.9 years at the base case price. Operating costs are also favorable, with average life-of-mine all-in sustaining costs of US$24.95/lb U3O8 (net of vanadium credits), positioning Ivana in the lower half of the global cost curve.
Advancement of the Ivana deposit has accelerated through a strategic joint venture. Strategic partner Abatare Spain SLU (COAM) is part of the Corporación América Group which has major stakes in the energy, airport, agribusiness, services, infrastructure, transportation, and technology sectors, with assets and operations in Argentina and 10 other countries. The partners have established a new operating company, Ivana Minerales S.A. (JVCO). Under the agreement COAM will spend up to US$35 million within 36 months to earn up to 49.9 percent indirect interest in Ivana. Furthermore, following the completion of a feasibility study, COAM can earn up to 80 percent by funding the costs and expenditures to develop and construct the project to commercial production. In addition, JVCO has the option to explore and acquire several exploration targets neighbouring Ivana.
Anit
The Anit property located north of Ivana, features a remarkable 15-kilometer airborne radiometric anomaly with extensive surface uranium and vanadium mineralization. Historical drilling along a 5.5-kilometer stretch averaged 2.6 meters at 0.03 percent U3O8 and 0.075 percent V2O5, indicating significant mineralization potential throughout the property. Blue Sky retains 100 percent control of this area, providing substantial upside beyond the Ivana deposit that is currently the focus of the COAM joint venture.
Santa Barbara
The Santa Barbara property represents the company's initial uranium discovery in the Rio Negro basin, made in 2006. This property exhibits widespread uranium and vanadium mineralization along an 11-kilometer surface trend. While exploration here is less advanced than at Ivana, the geological similarities and surface indicators suggest potential for both near-surface mineralization and deeper blind deposits that could be identified through future exploration campaigns.
ISR Projects
Blue Sky has strategically expanded its uranium project portfolio beyond Amarillo Grande with two new projects in the Neuquen Basin that target uranium deposits potentially amenable to in-situ recovery (ISR) methods. This approach to uranium extraction involves dissolving minerals in place using fluids that are then pumped to surface for processing, resulting in minimal surface disturbance and no tailings or waste rock generation. Globally, ISR methods account for approximately 57 percent of world uranium production.
Chihuidos Project
The 100 percent-controlled Chihuidos project encompasses 60,000 hectares with geological characteristics similar to productive ISR uranium operations elsewhere in the world. Blue Sky benefits from access to historical borehole and seismic data collected during previous oil and gas exploration in the region, allowing for more efficient target identification.
Corcovo Project
The Corcovo project adds another 20,000 hectares of prospective ground under option to Blue Sky. Like Chihuidos, the company is leveraging existing geological data to identify high-priority targets while advancing the permitting process for field exploration. These ISR projects represent significant growth opportunities for Blue Sky beyond its flagship Amarillo Grande Project.
San Jorge Basin Projects
Blue Sky has also secured strategic positions in the San Jorge Basin: the Sierra Colonia and Tierras Coloradas projects. While less advanced than the Amarillo Grande project, these properties have been selected based on favorable geological characteristics and historical indicators of uranium mineralization. The company is applying the exploration model and expertise developed at Amarillo Grande to efficiently evaluate and advance these new prospects. These projects represent Blue Sky's commitment to building a diverse portfolio of uranium assets across Argentina while maintaining focus on near-term development priorities at Ivana.
