Future Metals Unveils Cost-Effective Panton PGM Project Development Strategy Following Comprehensive Metallurgical Review

Comprehensive Review Consolidates Over 20 Years of Panton Technical Research

Future Metals engaged ResourcesWA Pty Ltd to conduct an extensive strategic review of the metallurgical and processing data accumulated at the Panton project since 2001. This review consolidated over two decades of testwork results and development concepts, including those forming the basis of the December 2023 Scoping Study. It evaluated ore sorting performance, grinding and milling requirements, flotation recovery and residence time, integration of reef and dunite feed streams, staged grinding, flash flotation applications, chromite and precious metal recovery, and the potential use of the existing Savannah processing infrastructure.

Managing Director Keith Bowes emphasized the review's importance, stating it "has consolidated more than two decades of technical work and identified several opportunities to simplify the development approach for Panton." The review provides a unified technical foundation for the next optimization phase. The company noted that historical metallurgical data were derived from diverse samples and conditions, necessitating further representative testwork to validate these findings for the upcoming Scoping Study. This approach ensures optimization recommendations are based on validated data rather than extrapolated historical results.

Single Flotation Train Offers Simplified, Cost-Effective Processing Alternative

A major outcome of the review is the proposal of a single flotation train processing blended feedstock as a lower-capital alternative to the separate reef and dunite flotation circuits outlined in the 2023 Scoping Study. This simplified processing strategy shifts from pre-separation of ore types to post-separation optimization, reducing capital expenditure by eliminating duplicate flotation infrastructure while maintaining metallurgical performance demonstrated in prior testwork. This approach addresses a key cost factor in mineral processing projects, where flotation circuit complexity often leads to substantial fixed costs.

The review also highlights that the nearby Savannah processing infrastructure could accommodate various development scales, pending further engineering and metallurgical validation. Utilizing existing facilities may lower initial capital requirements and simplify operational ramp-up. The single flotation train concept enables ore sorting technology to focus on upgrading feed quality by rejecting low-grade material, enhancing economic efficiency while maintaining quality control.

Ore Sorting Demonstrates PGM Grade Enhancement of 1.10 to 1.16 Times

Ore sorting testwork from 2015 and 2023 revealed a strong correlation between retained mass and recovery of PGMs, gold, and chromium. The review suggests rejecting 10% to 22% of feed mass could yield a PGM grade uplift between 1.10 and 1.16 times by preferentially removing barren or low-grade ore. This improves feed quality for flotation, reducing processing load and enhancing concentrate grades and recovery efficiency.

Previously, the 2023 Scoping Study aimed to separate reef and dunite via ore sorting to facilitate distinct flotation circuits. With the shift to blended feedstock, ore sorting can better fulfill its traditional role of upgrading feed by removing low-value material rather than segregating ore types. The data indicate consistent and reliable ore sorting performance, supporting its integration into the new Scoping Study.

Grinding Optimization Targets Energy Efficiency and Cost Savings

The review identified potential to lower grinding circuit power consumption through coarser or staged grinding methods. Given Australia's relatively high energy costs, reducing grinding energy requirements can significantly decrease operating expenses over the project lifecycle. Coarser and staged grinding can maintain mineral liberation while reducing milling energy intensity.

Staged grinding involves progressive ore size reduction across multiple circuits, allowing intermediate separation and removal of fully liberated material. This minimizes over-grinding and energy waste, particularly relevant for the blended reef and dunite feedstock with differing grinding characteristics. Incorporating these optimizations into the new Scoping Study will yield a more economically efficient processing cost structure compared to the 2023 baseline.

Flash Flotation and Reagent Adjustments Enhance Cost Efficiency

Additional optimizations include flash flotation, reagent system modifications, and flowsheet simplification. Flash flotation rapidly separates coarse particles early in the flotation process, improving recovery kinetics and reducing flotation residence time. This enables smaller flotation cell volumes or increased throughput, lowering capital and operating costs. Reagent adjustments, informed by extensive testwork, may improve recovery while reducing chemical usage.

Flowsheet simplification addresses redundancies and inefficiencies across the processing circuit without compromising recovery. These combined improvements are expected to significantly reduce capital and operating costs, enhancing the project's resilience against commodity price fluctuations and competitive pressures in the PGM sector.

Metallurgical Results Indicate Superior PGM Concentrate Grades

The review confirmed consistent flotation performance across multiple test programs and laboratories, including triplicate tests by Independent Metallurgical Operations (IMO) on reef and dunite samples. Concentrate grades potentially exceed those in the 2023 Scoping Study and surpass the 20-80 g/t PGM range typical of other Australian projects. Higher concentrate grades reduce refining costs and increase product value.

The 2023 Scoping Study assumed reef PGM head grade of 6.86 g/t, dunite at 1.55 g/t, and a combined head grade of 3.78 g/t based on 42% reef and 58% dunite blend. Flotation recoveries were 79% for reef and 77% for dunite, producing concentrate grades of 153 g/t and 26 g/t respectively. Resin-in-leach recoveries reached 84% for palladium and 92% for gold, with total PGM recovery at 87%. These metrics establish a robust baseline for further optimization. Superior concentrate grades relative to peer projects offer competitive advantages in downstream marketing and refining.

Optimizing Precious Metal and Chromite Recovery

The review identified further opportunities to enhance precious metal and chromite recovery, key by-product contributors to project economics. Gold and palladium recoveries in cyanide and resin-in-leach circuits using reef flotation tailings showed rapid kinetics, suggesting alternative processing options like gravity circuits combined with intensive cyanidation could reduce capital and operating costs compared to conventional methods. Faster reaction rates enable smaller equipment and shorter leach residence times.

Chromite flotation recovery in the 2023 Scoping Study achieved 73% at 1.25 Mt/a throughput, representing significant by-product value. The review highlights potential improvements through alternative circuit designs and reagent choices. Managing tailings containing precious metals and chromite presents complex but valuable multi-stream recovery opportunities. Incorporating cost-effective recovery methods for these by-products into the new Scoping Study will boost overall project value and metallurgical sustainability.

Upcoming Scoping Study to Integrate Review Insights and Focused Testwork

Future Metals will soon initiate a new Scoping Study that incorporates findings from the strategic review, the updated Mineral Resource Estimate, and prior Savannah processing plant engineering assessments. Targeted testwork will evaluate blended flotation feed performance, ore sorting on blended material, alternative grinding strategies including coarser and staged grinding, and cost-effective precious metal and chromite recovery methods. This phase is essential to validate optimizations and ensure the new Scoping Study relies on representative sample data rather than extrapolated historical results.

Managing Director Keith Bowes stated, "The next phase will focus on targeted testwork and engineering to explore lower-capital and lower-operating-cost processing options while maintaining the strong recoveries demonstrated previously. These results will directly inform a new Scoping Study aimed at defining a practical, scalable development pathway with flexibility for future expansion." This emphasis on scalability aligns with the company’s strategy to accommodate varying operational scales and market conditions. The forthcoming Scoping Study will offer a refined, economically optimized development blueprint beyond the December 2023 baseline, incorporating technological advancements and cost reductions identified through comprehensive technical consolidation.
