Hempalta Corp. (TSXV: HEMP) (‘Hempalta’ or the ‘Company’), a Canadian-based innovator in nature-based carbon credits, today provided an update on its ongoing corporate transformation and operational milestones.

As part of its previously announced strategic shift to focus exclusively on its high-growth carbon credit business, Hempalta has completed the wind down and closure of its processing facility in Calgary. The facility has now been vacated and decommissioned.

FCC Loan Update

In connection with the plant closure, the Company’s wholly owned subsidiary, Hempalta Processing Inc. (‘HPI‘) has received a notice of default from Farm Credit Canada (‘FCC‘) in respect of the Company’s obligations under its existing loan agreement and related security (the ‘Default‘). The notice cites technical defaults arising from the cessation of operations and FCC’s determination that there is a material adverse change. No monetary payment default has occurred to date.

Equipment Sales

In connection with the Default, and further to the previously announced marketing of the Company’s turn-key industrial hemp processing line, including biochar processing equipment (the ‘Equipment‘), the Company is pleased to announce that HPI has entered into a binding asset purchase agreement (the ‘Purchase Agreement‘) with an arm’s length third party for sale of the Equipment for cash consideration of USD$1,150,000 (the ‘Purchase Price‘) (the ‘Transaction‘). The Purchase Agreement includes the payment of a fifty percent deposit of USD$575,000 upon signing, and remains subject to standard closing conditions including but not limited to the receipt of necessary regulatory and shareholder approvals (the ‘Approvals‘), and receipt of the balance of the Purchase Price. In connection with the Purchase Agreement, certain insiders have signed voting support agreements in respect of shareholder approval of the Transaction.

Proceeds from the Transaction will be used to satisfy the outstanding amounts owed to FCC to satisfy the Default, and are also expected to be used to reduce outstanding corporate liabilities and strengthen the Company’s balance sheet. The Company expects to call its annual and special shareholders meeting to approve the Transaction and annual items in due course.

Carbon Credit Update

Hempalta is pleased to report continued growth and progress in its carbon credit business:

• For the 2024 crop year, approximately 29,000 tonnes of CO₂ sequestration have been calculated using the Company’s AI-powered MRV (Measurement, Reporting and Verification) platform. These credits are currently in final verification with Control Union, and once issued, will bring the Company’s total verified credits to over 44,000 tonnes when combined with the previously announced 15,325 credits issued for 2023.

Upcoming Industry Event Participation

Hempalta also announced its participation in Carbon Unbound East Coast, taking place May 21-22, 2025, in New York City. The Company will be showcasing its innovative hemp-based carbon credit methodology and actively engaging with global carbon buyers and partners.

‘We continue to execute on our focused carbon-first strategy while responsibly managing the wind down of legacy operations,’ said Darren Bondar, CEO of Hempalta. ‘We are continuing to advance our carbon credit platform, and seeing clear momentum in both our sequestration volumes and industry engagement.’

Radisson Mining Resources Inc. (TSXV: RDS) (OTCQB: RMRDF) (‘Radisson’ or the ‘Company’) is pleased to announce an expansion and extension of its current drill exploration program at its 100%-owned O’Brien Gold Project (‘O’Brien’ or the ‘Project’) located in the Abitibi region of Québec. This program expansion follows the recent completion of Radisson’s successful C$12 million financing and ongoing drilling that is demonstrating significant gold mineralization below the historic mine workings and the Project’s current Mineral Resources.

Exploration priorities will be as follows:

• An additional 30,000 to 40,000 metres of drilling. Approximately 18,000 metres of the new drilling will be completed in 2025 on top of the already budgeted 22,000-metre 2025 program. The balance of the new drilling will be completed in 2026. A fourth rig will be added to the Project in June;

• Expansion of the successful strategy of drilling beneath the historic O’Brien mine and the East O’Brien area of new Mineral Resources, to a depth of up to 2 kilometres (Figure 1);

• Continuance of the successful strategy of pilot holes and multiple wedges to give clusters of intercepts within the favourable Piché formation with an objective of achieving a drill-hole density appropriate, at a minimum, for a future Inferred Mineral Resource;

• Stepping back and looking at broader exploration opportunities, including separate deep exploratory holes beneath the historic Thompson-Cadillac mine located west of the O’Brien mine. This will be the first drilling conducted at Thompson-Cadillac since 2020 and its first deep drilling ever.

Matt Manson, President & CEO, commented: ‘Since late last year, we have been achieving consistent success with our ‘proof-of-concept’ strategy of drilling below the existing Mineral Resources at the O’Brien Gold Project with large step-outs. In particular, we are excited by what is developing with our drilling below the historic O’Brien mine workings, where multiple drill-holes have intersected high-grade gold within a large zone of multiple veins with good continuity. In Figure 2 we highlight the amount of coarse visible gold currently being logged in this drilling, both within holes with published assay results and those for which assay results are still pending. At this moment, we are in the process of greatly increasing the known scope of gold mineralization at O’Brien with each new hole. We believe an exploration target of between 3 and 4 million ounces is a reasonable objective for the Project should the style of mineralization we are seeing continue to our exploration horizon of 2,000 metres depth.’

Matt Manson continued: ‘Consequently, we are announcing today a considerably expanded effort to target these new areas of mineralization with additional deep drilling. In this news release we provide a discussion of the techniques we are using: pilot holes, wedges and directional drilling; and we provide a discussion of the context of our exploration: that O’Brien should not be considered a bespoke curiosity with impressive but localised high-grade gold, but is instead a broader system of mineralization with significant scale potential.’

Drilling Context: O’Brien Mineral Resources, Cut-offs and Future Mineral Resources

The 2023 NI 43-101 compliant Mineral Resource Estimate (‘MRE‘) for the O’Brien Gold Project (‘Technical Report on the O’Brien Project, Northwestern Québec, Canada’ effective March 2, 2023) comprises 0.50 million ounces of Indicated Mineral Resources (1.52 million tonnes at 10.26 g/t Au), and 0.45 million ounces of Inferred Mineral Resources (1.60 million tonnes at 8.66 g/t Au). This estimate utilizes a 4.5 g/t Au bottom cut-off, at US$1,600 per oz Au with a C$:US$ exchange of 1.25, and 85% metallurgical recovery, amongst other assumptions. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Historic production at the O’Brien Mine between 1926 and 1957 is estimated at 0.59 million ounces from 1.2 million tonnes at 15.25 g/t Au.

In Radisson’s view, both the 2023 MRE and the historic mining represent ‘high-graded’ estimates of actual gold content in their respective volumes. In the March 2023 Technical Report for the MRE, sensitivity estimates based on alternate cut-off grades were presented. Using a 3.0 g/t Au cut-off, the Indicated Mineral Resources sensitivity was 0.58 million ounces (2.12 million tonnes at 8.46 g/t Au) and the Inferred Mineral Resource sensitivity was 0.68 million ounces (3.67 million tonnes at 5.79 g/t Au), increases of 15% and 53% respectively in contained ounces over the MRE at a 4.5 g/t Au cut-off grade.

Radisson believes that the O’Brien Project should be evaluated on the basis of a lower cut-off grade, yielding more ounces in more tonnes with greater continuity at lower average grades. Radisson’s disclosure of drill results since 2024 has been based on an assumed cut-off grade of 3 g/t Au for intercepts with mineral resource potential, and Figures 1 and 2 graphically illustrate the MRE at multiple cut-offs including 3 g/t Au. With this view, and given the recent successful drilling below the current MRE and the historic mine, Radisson believes the exploration potential of the Project is between 3 and 4 million ounces should the current density of gold mineralization, in ounces per vertical metre, continue to a nominal exploration horizon of 2,000 metres depth.

By the end of the current program, Radisson will have completed an additional 80,000-90,000 metres of new drilling since the publication of the 2023 MRE. At this time the Company will assess the completion of an updated Mineral Resource estimate. To this end, current and future drilling will be designed to attain a drill-hole density appropriate, at a minimum, to an Inferred Mineral Resource.

Drilling Approach: Deep Pilot Hole + Wedge Drilling in O’Brien’s Core Area

Radisson’s deep drilling program employs a cost-effective and time-efficient strategy that leverages both wedge and directional drilling to generate multiple branches intersecting the prospective Piché Group formation. A full-time directional drilling team is integrated with contract drillers, enhancing precision in targeting and increasing operational flexibility. Drill-hole trajectories are monitored daily to ensure accurate deviation and allow for real-time adjustments. This system provides significant optionality for subsequent branches, enabling Radisson to adapt targets without compromising the integrity of the pilot hole for future exploration.

The O’Brien project has long been known for its occurrence of coarse gold. To address the challenges this presents in sample representativity, where for example, conventional fire assay may under-report grade by missing so-called ‘nuggets’, Radisson has implemented a screen metallics assay method in intervals containing or proximal to visible gold. As part of ongoing efforts to improve assay reliability and scalability, the Company will soon begin testing PhotonAssay technology. This next-generation technique offers a more advanced and comprehensive solution to the coarse gold challenge by enabling rapid, non-destructive analysis of larger sample volumes.

Anteros Metals Inc. (CSE: ANT) (‘Anteros’ or the ‘Company’) is pleased to report results from recent assessment work at its 100% owned Strickland VMS Property (‘Strickland’ or the ‘Property’) in southwestern Newfoundland. The work focused on the digitization and interpretation of multi-element geochemical data from historic trenching, advancing drill targeting efforts on this underexplored polymetallic volcanogenic massive sulphide (‘VMS’) system.

Prior to its public listing, Anteros commissioned the compilation, digitization, and 3D geological modelling of the Strickland VMS system in 2023 and 2024. This foundational work established a strong understanding of Property’s geology, alteration, and structure, and enhanced the understanding of multiple mineralized zones along a 1.4 kilometre trend (Figure 1). Since going public, Anteros has advanced the project through targeted follow-up, focusing on geochemical vectoring and priority zone refinement. The 2025 program confirmed compelling indicators of feeder-style alteration and mineralization in underexplored zones and highlighted several new high-priority exploration targets.

Mineralization Highlights:

• Feeder-style alteration and mineralization confirmed: Compilation of 95 multi-element assays from 2012 trenching, integrated with historical drill data in 3D models, is helping to vector toward the potential VMS core and optimize future drill targeting.
• Copper Zone: Now a high-priority target, with historical trench sampling returning up to 3.7% Cu and 3.25 g/t Au over 1 metre (Cu-C1, Table 1), alongside elevated cobalt and intense alteration – features consistent with VMS feeder conduits.
• Gold Zone: Historical trenching returned 1-metre intervals up to 3.2% Cu and 1.32 g/t Au (Au-C1, Table 1), with alteration and elemental ratios indicating proximity to a hydrothermal center. This zone has never been drill-tested.
• Main Zone and Main Extension: Historical trench samples demonstrate elevated Pb-Zn-Ag over extended strike lengths, consistent with stratiform VMS-style mineralization.

‘The presence of multiple, mineralized zones along an over 1 kilometre trend indicates a significant VMS system,’ said Trumbull Fisher, Anteros CEO. ‘Specifically, the underexplored feeder-style alteration and high-grade gold-copper intervals of the Copper and Gold Zones have emerged as immediate exploration priorities.’

Next Steps

Building on the promising results to date, Anteros is planning a focused exploration program that includes:

• Field verification of historical trench and drill collar locations to validate spatial accuracy
• Integration of additional multi-element geochemistry into 3D models to refine and prioritize drill targets
• Hyperspectral and induced polarization (‘IP’) surveying to image alteration halos and sulphide concentrations at depth
• Diamond drilling of the Copper and Gold Zones, which remain largely untested despite returning high-grade trench results

About The Property

Strickland is held 100% by Anteros and is located approximately 85 kilometres south of Stephenville, within the Exploits Subzone of the prolific Dunnage Zone in central Newfoundland – an area renowned for hosting world-class VMS deposits. The Property hosts seven documented zones of copper (‘Cu’), lead (‘Pb’), zinc (‘Zn’), silver (‘Ag’), gold (‘Au’) mineralization along a 1.4 kilometre trend.

Mineralization at Strickland is interpreted to represent a bimodal-felsic (Kuroko-type) VMS system. Documented sulphide mineralization includes sphalerite, chalcopyrite, galena, and pyrite in high-grade polymetallic horizons-positioning the Property within the scope of Canada’s Critical Minerals Strategy.

In 1981, D.R. Prince of Falconbridge Nickel Mines Ltd. reported the following historical mineral inventories:

• 260,000 tonnes at 195 g/t Ag and 5.25% combined Pb and Zn at the Main Zone,
• 15,000 tonnes at 480 g/t Ag and 2% combined Pb+Zn at the Silver Hill Zone, and
• 750,000 tonnes at 2% combined Pb+Zn at the Main Extension Zone

(Source: Falconbridge Nickel Mines Ltd., Internal Report, Geofile #011O/16/0139)

These estimates are considered historical in nature and were not prepared using current Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’) Definition Standards. A Qualified Person has not completed sufficient work to classify the historical estimates as current mineral resources, and Anteros is not treating them as current mineral resources. The Company considers these estimates relevant to the extent that they indicate the presence of significant mineralization and support continued exploration.

The reliability of the estimates is uncertain due to the age of the data, incomplete documentation of estimation methods, and the lack of modern QA/QC protocols. The original report does not provide specific cut-off grades, metal price assumptions, or a description of the estimation methodology. To verify or upgrade these estimates to current standards, Anteros would need to complete field validation of historic trench and drill collar locations, resample archived or in situ material using modern analytical methods, apply current QA/QC protocols, and complete a compliant geological model that supports estimation in accordance with CIM Definition Standards.

Since acquiring the Property in March 2022, Anteros has completed comprehensive digital compilation and geological modelling of historical data including airborne and ground geophysics, geological mapping, geochemistry, and over 7,000 metres of historical drilling and trenching.
