ILC Critical Minerals Ltd. (TSXV: ILC,OTC:ILHMF) (OTCQB: ILHMF) (FSE: IAH0) (‘ILC’ or the ‘Company’) announces that it has not exercised, nor has it been able to extend, its option to buy 100% of Lepidico (Mauritius) Ltd. (‘Lepidico Mauritius’) from Lepidico (Canada) Inc. (‘Lepidico Canada’) which expired on February 27, 2026. This company controls 80% of the Karibib lithium, rubidium and cesium project in Namibia.

The ILC board had carefully considered the financial and legal risks of the transaction, and supported the exercise of the option. The board had the required funding ready. However TSX Venture Exchange (‘TSXV’) did not give the required approval in time to ILC that would have enabled ILC to complete the transaction. It might have been possible to extend the expiry date of the option further, but this would have required ILC to provide additional working capital to Lepidico Canada. The TSXV went further and also prevented ILC from lending more money for working capital to Lepidico Canada. This had the practical effect on ILC that the option could neither be exercised nor extended.

This is a setback for ILC’s plans in Southern Africa because Karibib has a large lithium resource, the biggest known rubidium resource in Africa, and enough cesium for about one year of world use, and it had already reached Definitive Feasibility Study stage under JORC in 2020. Such advanced stage development projects are hard to find, and the board believed after months of work on the transaction that it could have added considerable shareholder value albeit with some risk.

Lepidico Canada’s board felt that it was not able to continue further as a viable company without the extra funds needed for its working capital needs. While ILC’s board would have been willing for ILC to offer this, the block by TSXV made this impossible to offer. As a result Lepidico Canada has now changed ownership. There is still a possibility of ILC being offered involvement in this project, in which case the ILC board would allow an extended period for TSXV’s review processes to complete in such a manner that gives a greater chance of allowing a favourable outcome from TSXV. Obviously however such an outcome cannot be assumed.

About ILC Critical Minerals Ltd.

ILC Critical Minerals Ltd., formerly International Lithium Corp., has exploration activities in Ontario, Canada, with intentions to expand into Southern Africa. It has projects at various stages, ranging from Preliminary Economic Assessment at Raleigh Lake to Pre-Drilling at Wolf Ridge. The primary target metals in Canada are lithium, rubidium and copper. There are three projects (two in Ontario and one in Ireland) in which ILC has sold its share, but where the Company stands to receive future payments from either a resource milestone being achieved or from a Net Smelter Royalty.

While the world’s politicians remain divided on the future of the energy market’s historic dependence on oil and gas and on ‘Net Zero’, there is in any scenario an ever-increasing and significant demand for electricity driven by AI and data centres, and by a likely unstoppable momentum towards electric vehicles and grid-scale electricity storage. All of these contribute to rising demand for lithium, copper, and other metals. Rubidium is also a critical metal, strategic for high-precision clocks, space technology, and improving the performance of certain types of solar panels. ILC has seen the politically driven, increasingly urgent push by the USA, Canada, the EU, and other major economies to safeguard their supplies of critical minerals and to become more self-sufficient. The Company’s Canadian and Southern African projects, which contain lithium, rubidium, cesium and copper, are strategic in this regard.

The Company’s key mission for the next decade is to generate revenue for its shareholders from lithium, rubidium and other critical minerals while also contributing to the creation of a greener, cleaner planet and less polluted cities.

This includes optimizing the value of ILC’s existing projects in Canada as well as finding, exploring and developing projects that have the potential to become world-class deposits. The Company has announced that it regards Southern Africa as a key strategic target market and it has applied for and hopes to receive EPOs in Zimbabwe. The board hopes to make further announcements on the portfolio developments over the next few weeks and months.

The Company’s interests in various projects now consist of the following, and in addition, the Company continues to seek other opportunities:

The Company’s primary strategic focus at this point is on the Raleigh Lake Project, comprising lithium and rubidium, and the Firesteel copper project in Canada, as well as obtaining EPOs and mineral claims in Zimbabwe.

The Raleigh Lake Project now encompasses 32,900 hectares (329 square kilometres) of mineral claims in Ontario and represents ILC’s most significant project in Canada. To date, drilling has occurred on less than 1,000 hectares of the Company’s claims. A Preliminary Economic Assessment was published for ILC’s lithium at Raleigh Lake in December 2023, with a detailed economic analysis of ILC’s separate rubidium resource still pending. This showed, for the lithium only and not yet taking into account the rubidium, a Post-tax NPV of CAD$342.9 million and a Post-tax IRR of 44.3% p.a. This was based on a spodumene price of US$2,350 per tonne. As at March 3, 2026 the spot spodumene price was back up to US$ 2,220 per tonne. Raleigh Lake is 100% owned by ILC, free from any encumbrances and royalties. The Raleigh Lake Project boasts excellent access to roads, rail, and utilities.

A continuing goal has been to remain a well-funded, strategically run company that turns ILC’s aspirations into reality. Following the disposal of the Mariana project in Argentina in 2021, the Mavis Lake project in Canada in 2022, and the Avalonia project in 2025, ILC has continued to generate sufficient cash inflows to advance its exploration projects.

With increasing demand for high-tech rechargeable batteries used in electric vehicles, energy storage, and portable electronics, lithium has been dubbed ‘the new oil’. It is a key part of a green, sustainable economy. By positioning itself on projects with significant resource potential and solid strategic partners, ILC aims to become a preferred lithium and critical minerals resource developer for investors and to continue building value for its shareholders throughout the 2020s, the decade of battery metals.

Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) (‘Blackrock’ or the ‘Company’) is pleased to announce the issuance by the Nevada Department of Environmental Protection (NDEP), through the Bureau of Air Pollution Control, the Class II Air Quality and Surface Disturbance Permit (the ‘Permit’) for the Company’s Tonopah West mineral project (‘Tonopah West’) located along the Walker Lane Trend in Nye and Esmeralda Counties, Nevada, USA.

The Permit allows for the disturbance of up to 150 acres (60.7 Hectares) at Tonopah West with appropriate dust control measures and an ongoing program using the best practical methods to prevent particulate matter from becoming airborne. The term of the Permit is five (5) years, which can be extended and modified as Tonopah West moves toward permitting and construction of its proposed exploration decline, test mining and bulk sample extraction programs.

Data collection continues for the hydrogeological and geochemical programs that will form the basis for the Water Pollution Control Permit. Five humidity cells are in process to review acid generating potential of the waste and mineralized lithologies that will be encountered and transported to the surface during the tunneling and construction of the exploration decline including stockpiles for mineralized material mined as part of the bulk sample program.

The hydrogeological program is designed to understand the groundwater dynamics focused on potential flow and volumes to support required management and disposal as needed during the test mining and bulk sample phase of the program. Waste dump, stockpiles and portal entry engineering designs are on schedule and will be completed and used to calculate surface disturbance that will be the cornerstone for the Modification to the Nevada Reclamation Permit. The permitting process is on schedule with all permits anticipated by mid-2027. Once all permits are in hand, the Company will decide when to commence with the exploration decline, test mining and bulk sample extraction programs at Tonopah West.

Radisson Mining Resources Inc. (TSXV: RDS,OTC:RMRDF) (OTCQB: RMRDF) (‘Radisson’ or the ‘Company’) is pleased to report an updated Mineral Resource Estimate (‘MRE’) at its 100%-owned O’Brien Gold Project (‘O’Brien’ or the ‘Project’) located in the Abitibi region of Québec. The Company is currently undertaking a fully-funded 140,000-metre step-out drill program at the Project with the objective of determining the scope of mineralization to a depth of 2 kilometres. This program commenced in 2025 and is expected to continue through the first half of 2027. Today’s updated MRE is an interim report that demonstrates the impact of recent drilling successes completed as of December 31, 2025. Highlights include:

• 82% increase in Inferred Mineral Resources from step-out drilling intersecting new mineralization, with 1.69 million ounces (‘Moz’) in 10.37 million tonnes (‘Mt’) at 5.08 grams per tonne (‘g/t’) gold (‘Au’);

• 8% increase in Indicated Mineral Resources with 0.63 Moz in 3.49 Mt at 5.59 g/t Au;

• Estimated using US$2,500/oz Au and 2.2 g/t Au cut-off, with a refined geological model and capping strategy, establishing the go-forward basis for future, modern mine development.

Matt Manson, President and CEO: ‘Today we report the first of several planned, step-by-step updates to the MRE at the O’Brien Gold Project, quantifying the impact of our recent drilling success and establishing a clear foundation for future, modern mine development. With just 25% of our 140,000 metre step-out drill program completed, the new vein mineralization delineated beneath the historic mine workings and the previous mineral resource volume (Radisson news release dated February 12, 2026) has resulted in an 82% increase in the quantity of Inferred Mineral Resources, now 1.69 Moz (10.37 Mt at 5.08 g/t Au). At the same time, we have refined the estimate of Indicated Mineral Resources, incorporating more tonnes at a lower average grade for an 8% increase in contained ounces, now 0.63 Moz (3.49 Mt at 5.59 g/t Au). Our estimates utilize a 2.2 g/t Au cut-off at a reasonable gold price assumption of US$2,500/oz.’

‘The former O’Brien Mine was known for high-grade ore-shoots mined in small volumes. Mining ended in 1957 with the gold price at US$35/oz. Significant volumes of mineralized vein material, below what we believe to have been a 7 g/t to 8 g/t Au cut-off, were left untouched. Now, we are presenting the Project as it should be viewed for future development: not as a bespoke deposit of extreme grade and limited scale, but as an extensive Abitibi vein deposit with a substantial inventory of mineralized material amenable to modern mechanized mining at higher throughput.’

‘Our step-out drill campaign at O’Brien is ongoing with up to eight rigs. We expect to complete 72,500 metres in 2026 and 32,500 metres in the first half of 2027. This is in addition to the meterage supporting today’s updated MRE. The vein mineralization system we have been intersecting is open at depth. In fact, since our step-out drilling began in the fall of 2024, we have been seeing an impressive 84% success rate in intercepting classic O’Brien quartz-sulphide-gold veins with grades and thicknesses consistent with today’s updated MRE. Looking to a 2-kilometre exploration floor, we believe an appropriate Exploration Target at O’Brien is another 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. We expect to complete further step-by-step updates to the MRE as our drilling progresses.’

Cautionary statement: Readers are cautioned Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues including risks set forth in Radisson’s filings made with Canadian securities regulatory authorities. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Mineral Resource Estimate (effective January 31, 2026)

The MRE is based on 428,440 metres of drilling completed to the end of December 31, 2025, and has been authored by SLR Consulting (Canada) Ltd. (‘SLR‘). The estimate utilizes a 2.2 g/t Au cut-off at US$2,500/oz and makes certain assumptions on mining and processing costs, currency exchange rate, and metallurgical recovery (Table 1 and Figure 1). A wireframe vein model prepared by Radisson and reviewed by SLR constrains the estimate and applies a minimum width of 1.2 metres. Individual assays are capped at 60 g/t Au prior to compositing to full width of the veins, and the block model utilizes 5 by 2 by 5 metre blocks consistent with recent mine design studies.

Table 1: Mineral Resource Estimate, Effective January 31, 2026

An MRE for the Project was previously published in March 2023 (Radisson news release dated March 2, 2023) based on 325,509 metres of drilling completed to the end of 2022. Indicated Mineral Resources (effective March 2, 2023) were estimated at 0.50 Moz (1.52 Mt at 10.26 g/t Au) with additional Inferred Mineral Resources of 0.45 Moz (1.60 Mt at 8.66 g/t Au). The 2023 study applied a 4.5 g/t Au cut-off at US$1,600/oz Au.

In July 2025, Radisson published a Preliminary Economic Assessment (‘PEA‘) for the Project that utilized the 2023 estimate re-blocked by SLR in the Z-direction from 10 metres to 5 metres to allow for more flexible underground mine design. A cut-off of 2.2 g/t Au at US$2,000/oz Au and an updated set of economic criteria were applied in the re-blocking exercise consistent with the parameters used for the optimization of the PEA’s underground mine schedule. No other changes were made. Indicated Mineral Resources (effective May 6, 2025) were estimated at 0.58 Moz (2.20 Mt at 8.22 g/t Au) with additional Inferred Mineral Resources of 0.93 Moz (6.67 Mt at 4.35 g/t Au).

The updated MRE released today benefits from 66,387 metres of additional drilling in 122 drill holes conducted between 2023 and 2025, which is the most significant factor in the increase of Inferred Mineral Resources (Figure 2). Radisson has also validated an additional 36,544 meters of historic drilling. The updated MRE utilizes similar estimation parameters to previously, but a more restrictive approach to capping. In the March 2023 estimate, and as incorporated in the re-blocked May 2025

estimate, capping at 40 g/t Au was applied to the full-length composites. In the updated MRE, capping has been applied at 60 g/t Au to the underlying assays prior to compositing. This has the effect of reducing the average grade by approximately 12%, and in the opinion of Radisson and SLR is an appropriate approach to a narrow high-grade vein deposit such as O’Brien.

Compared to previous estimates, the aggregate impact on the Indicated Mineral Resources of the new drilling, the 2.2 g/t Au cut-off, and the updated capping strategy has been to add more tonnes at a lower average grade for an overall increase in contained ounces. The aggregate impact of these three factors on the Inferred Mineral Resources has been the addition of more tonnes at a higher average grade for an overall increase in contained ounces. Indicated Mineral Resources have increased by 8% to 0.63 Moz, based on an increase in tonnes of 58% to 3.49 Mt and a decrease in grade of 32% to 5.59 g/t Au. Inferred Mineral Resources have increased by 82% to 1.69 Moz, based on an increase in tonnage of 55% to 10.37 Mt and an increase in grade of 17% to 5.08 g/t Au.

O’Brien’s system of Quartz-Sulphide-Gold vein mineralization remains open to depth across a broad front beneath the historic mine workings and the updated MRE. The potential continuation of this mineralization to a 2 kilometres depth defines an Exploration Target of an additional 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

A New Vision for the O’Brien Gold Project

The historic O’Brien mine produced over half a million ounces of gold at an average grade exceeding 15 g/t Au. It is clear that the former mine was ‘high-graded’, with manual mining methods applied to the highest-grade veins and ore shoots at an estimated cut-off grade of 7 g/t to 8 g/t Au. Parallel but lower-grade mineralized zones, which would be well above an economic cut-off grade today, were left unmined.

The updated MRE does not incorporate any mineral resources potentially remaining in the former mine. However, in applying the lower grade cut-off of 2.2 g/t Au based on a gold-price estimate of US$2,500, the new estimate captures the overall volume attributes of the O’Brien mineralizing system, with more tonnes and more ounces at a lower average grade. This has the benefit of improving the continuity of mineralization for future mine planning, with larger stopes and more development headings supporting a higher potential mining rate. The Project has existing mining infrastructure to support such a vision, such as a shaft in the former mine extending to a 1,000 metres depth and multiple mills in the region with significant future capacity.

Table 2 illustrates sensitivities on Indicated and Inferred Mineral Resources and the MRE block model based on cut-off grade. These are:

• a) 8.0 g/t Au (US$700/oz) representing the former mine,

• b) 4.5 g/t Au (US$1,250/oz) representing the MRE effective March 2, 2023,

• c) 2.2 g/t Au (US$2,500/oz) representing the updated MRE, and

• d) 1.5 g/t Au (US$3,800/oz) representing the recent long-term consensus price of gold.

The comparison clearly indicates the relationship between volume and grade based on cut-off, the directionality of steeply-plunging grade shoots at O’Brien, and the increased continuity of mineralization achieved at progressively lower cut-offs.

Gold Mineralization at O’Brien and Step-Out Drill Program

Gold mineralization at O’Brien occurs within quartz-sulphide veins developed primarily within the interlayered mafic volcanic rocks, conglomerates, and porphyritic andesitic sills of the Piché Group occurring in contact with the regionally significant Larder Lake-Cadillac Break (‘LLCB’). Individual veins are generally narrow, ranging from several centimetres up to several metres in thickness, and are associated with mineralized alteration envelopes of up to several metres in thickness. Multiple veins occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. As mapped at the historic O’Brien mine, and now replicated in the modern drilling, individual veins have well-established lateral continuity, with steeply plunging grade shoots developed over significant lengths.

Since the end of 2024, Radisson has been pursuing a program of broad step-out drilling at O’Brien with the objective of determining the overall scope of mineralization at the Project to a depth of 2 kilometres (Figure 1). The priority is the quantity and distribution of mineral resources with step-outs rather than in-filling to upgrade the classification of the existing mineral resources.

This drilling is accomplished with pilot holes followed by wedges and directional drilling to maximize drill efficiency. In October 2025, Radisson announced the expansion of the program to 140,000 metres employing an eventual eight drill rigs (see Radisson news release dated October 16, 2025). An initial 35,000 metres of the program were completed in 2025, with 72,500 metres budgeted for 2026, and a further 32,500 metres scheduled for the first half of 2027.
