Exploration Highlights Resource Growth Potential
In February 2024, Ascendant Resources completed a detailed gravity survey over the Venda Nova North and South Zones. This survey was instrumental in mapping the known gravity footprint of the existing Primary Massive Sulphide (PMS) deposits and identifying previously unrecognized targets. The program identified four new high priority targets for ongoing follow up and suggests the potential for significant resource growth remains at Lagoa Salgada. Refer to Press Release dated February 28, 2024, for more details [Link to Press Release].

As announced on November 4, 2024, Ascendant initiated a precision drill program targeting the newly identified anomalies. To date, drilling has targeted the SW North Zone. A gravity anomaly west and below the North Deposit.

Recent drilling has unveiled a previously unrecognized copper-rich feeder system west of the Venda Nova North Deposit. This discovery, characterized by high-grade stringer sulphide mineralization opens new resource potential for ongoing drilling. The mineralization exhibits distinct geological characteristics:

• Fault Zone Transition: Drilling intersected a fault zone transitioning into acid volcanic formations, marked by intense sericitization and sulphide dissemination.

• Chalcopyrite bearing Zones: Based upon visual review Stringer mineralization intersected between 449.50m and 454.30m depth showcased significant chalcopyrite, accompanied by traces of galena, confirming the presence of robust copper mineralization.

• Expansive Potential: The observed sulphide dissemination from 400m depth strongly suggests proximity to a massive sulphide lens, with potential to significantly expand the resource base.

Assays are currently pending and expected to be released before year end. The discovery of this potential feeder zone warrants further follow-up drilling to determine if a proximal massive sulphide lens can be located. While the current drill plan is limited in scale, initial results appear highly encouraging to have outlined a new, separate zone to grow the overall resource base at Lagao Salgada.

Metallurgy
Metallurgical test work programs have continued subsequent to the successful Phase I metallurgical test works and have demonstrated the ability to produce high-grade concentrates with competitive recovery rates across multiple domains:

• Zinc Recovery and Grade: Achieved recoveries of approximately 79% with grades exceeding 45% zinc.

• Lead Concentrates: Delivered recoveries of 53% with grades up to 45% in the Stockwork domain.

• Copper Recovery: Recoveries range from 48% to 60%, with concentrate grades surpassing 20%.

The above results establish Lagoa Salgada's concentrates as highly competitive. Notably, mercury-reduction techniques have improved concentrate marketability, with mercury levels reduced to below 500 ppm in zinc concentrates after thermal treatment.

Phase II: Breakthroughs and Ongoing Optimization
The Phase II metallurgical test work at Lagoa Salgada is focused on unlocking additional value across multiple mineralized domains, building on the progress achieved during Phase I.

Gossan Domain Optimization in Final Stages
The metallurgical optimization of the Gossan domain is nearing completion, with significant advancements in lead and vanadium recoveries. Initial rougher tests have already demonstrated:

• Lead Recoveries of 45% and Vanadium Recovery of 35%, with ongoing efforts to refine recovery efficiency by adjusting depressant dosages.

• Precious metal recoveries have also ranged within 50-60% suggesting the potential to remove the requirement for leaching to recover this value.

• Strong reporting of Tin to the tailings suggesting the potential to also improve concentrate and recoveries for the Tin concentrate.

These optimizations ensure higher-grade concentrates suitable for cleaner stages while targeting additional improvements in recovery rates to maximize economic returns​​.

Following the success in the Gossan domain, Phase II test work will now expand to the other key mineralized zones at Lagoa Salgada. Fresh core samples from these domains from the current drill program have been meticulously prepared and stored in a freezer container to prevent oxidation. These samples are now being transported to Wardell Armstrong and Petrolab, where advanced metallurgical testing will commence. The enhancement in recoveries seen in the various domains and the reduction in deleterious elements are expected to further enhance overall project economics.
