Southern Palladium Repositions Bengwenyama as Dual PGM-Chrome Co-Product Operation

Bengwenyama’s Strategic Location Within the Bushveld Complex Tier-1 District

Southern Palladium holds a 70 percent interest in the Bengwenyama Project, which is positioned in prime mining real estate within the Eastern Limb of the Bushveld Complex in South Africa. The project is located in the Mpumalanga province, approximately 300 kilometres east of Johannesburg, in an established platinum group metal mining region. The Eastern Limb hosts multiple operating and development-stage PGM assets operated by established producers including Implats, Northam Platinum, and Valterra Platinum, alongside advanced projects such as Two Rivers and Mototolo. This clustering of world-class assets underscores the tier-1 nature of the Bengwenyama location and the proven mineral endowment of the Eastern Limb geological setting.

The Bushveld Complex is the world’s largest platinum group metal resource base, and the Eastern Limb is increasingly recognised as a prolific centre for PGM exploration and development. Southern Palladium’s ownership of Bengwenyama within this district positions the company alongside major international and regional mining operators in a proven, infrastructure-rich mining jurisdiction. The proximity to existing mining operations, processing facilities, and skilled labour pools provides operational and cost advantages for project development. The strategic importance of the Bushveld Complex resource base to global PGM supply chains ensures that tier-1 assets in this district attract significant institutional and commercial interest from investors, off-takers, and potential development partners.

Chromite Recovery Breakthrough Transforms Chrome From Minor Credit to Major Revenue Stream

The most significant development announced in the latest company update is the dramatic improvement in chromite recovery through updated metallurgical testwork. In the prefeasibility study and optimised prefeasibility study, chromite recovery was modelled at 30 percent, treating chrome essentially as a minor by-product credit in the PGM project economics. However, definitive feasibility study testwork has demonstrated chromite recovery rates of 85.6 percent, representing a 55.6 percentage point improvement. This breakthrough recovery rate has triggered a fundamental repositioning of the project from a PGM operation with secondary chrome value into a genuine PGM-chrome co-product development with balanced revenue contributions from both commodity streams.

The improvement in chromite recovery directly translates into significantly higher chrome concentrate output. At a run-of-mine feed rate of 2.4 million tonnes per annum, the prefeasibility study assumed only 0.35 million tonnes per annum of chrome concentrate output. Definitive feasibility study testwork now projects approximately 1.054 million tonnes per annum of chrome concentrate, representing a threefold increase in absolute chrome production volume. The chrome concentrate grade remains stable at approximately 42 percent to 42.2 percent Cr₂O₃. At May 2026 benchmark pricing of US$320 per tonne for 42 percent Cr₂O₃ concentrate CIF, this scaled-up chrome production becomes a material revenue contributor alongside PGM sales. The company did not disclose the incremental revenue impact in monetary terms in the announcement, but the volumetric shift from 0.35 million tonnes per annum to 1.054 million tonnes per annum at current market prices indicates a meaningful enhancement to project cash flows and resilience.

Enhanced PGM Recovery and Concentrate Grade Improvements Drive Processing Economics

In parallel with the chromite recovery breakthrough, Southern Palladium’s latest metallurgical testwork has delivered material improvements to PGM processing outcomes. Overall PGM recovery increased from 85.3 percent in the prefeasibility study to 87.6 percent in definitive feasibility study testwork, a gain of 2.3 percentage points. More dramatically, the PGM concentrate grade improved from 100 grams per tonne (4E) in the prefeasibility study to 443.6 grams per tonne (4E) in definitive feasibility study testwork, representing approximately a 4.4 times improvement. The final primary PGM concentrate achieves 505.9 grams per tonne on a 6-element (6E) basis, comprising platinum (44.8 percent), palladium (34.4 percent), ruthenium (9.4 percent), rhodium (7.6 percent), iridium (2.5 percent), and gold (1.3 percent).

These concentrate quality improvements carry direct operational and economic significance. Higher concentrate grades reduce mass throughput requirements, lower equipment sizing and energy consumption in subsequent processing stages, and improve the commercial attractiveness of the material to smelters and refiners. The PGM concentrate mass pull of only 1.2 percent of total run-of-mine feed indicates efficient liberation and concentration of valuable metals. The prill split across six PGM elements, combined with by-product gold, provides diversification within the PGM revenue stream and reduces single-commodity price exposure. The company did not disclose the revised net revenue benefit per ounce of PGM in the announcement, but the combination of higher recovery rates, elevated concentrate grades, and reduced processing intensity suggests material improvement to stage-1 and stage-2 cash operating costs compared to the prefeasibility study baseline.

Simplified Processing Circuit With DMS Pre-Concentration Minimises Capital and Operating Intensity

The definitive feasibility study has refined the processing flowsheet to a simplified, conventional circuit that improves technical performance while reducing capital and operational demands. The core innovation is a dense media separation (DMS) pre-concentration stage upstream of the primary ball mill circuit. This stage rejects waste material before primary milling, upgrading run-of-mine feed from 5.2 grams per tonne (3E) to 7.2 grams per tonne (3E) while losing only 1.2 percent to 2.2 percent of contained PGM. The DMS circuit achieves mass rejection of 24 percent to 31 percent, effectively reversing dilution before the mill and reducing the total mass throughput in milling and flotation circuits by approximately one-half.

The flowsheet also incorporates a coarser primary grind (30 percent passing 75 micrometres versus 60 percent in the prefeasibility study), which protects chromite particles from over-grinding and supports higher chrome recovery. A secondary flotation circuit recovers the PGM deficit created by the coarser primary grind, maintaining overall recovery efficiency. An interstage chrome flotation stage exploits liberated chromite between primary and secondary flotation circuits. This tiered approach delivers dual benefits: improved chromite recovery from 30 percent to 85.6 percent, and the creation of multiple saleable product streams (coarse chrome concentrate, fine chrome concentrate, primary PGM concentrate, and secondary PGM concentrate). The economic signal of the DMS pre-concentration is clear: lower mass through milling and flotation reduces equipment sizing, energy draw, and operating intensity, directly improving unit production costs and project economics.

Staged Development Architecture Balances Capital Deployment With Revenue Generation

The optimised prefeasibility study early 2025 outlines a two-stage development approach that manages capital deployment and allows staged revenue generation. Stage 1 targets production of 200,000 ounces per annum (6E) and requires a peak funding requirement of US$279 million, representing 38 percent less capital than the original prefeasibility study. The Stage 1 development is economically viable on a standalone basis, demonstrating a 21.8 percent internal rate of return at the price assumptions used (platinum US$1,200 per ounce, palladium US$1,100 per ounce, rhodium US$6,190 per ounce, ruthenium US$450 per ounce, iridium US$4,650 per ounce, gold US$1,950 per ounce, nickel US$18,249 per tonne, copper US$8,708 per tonne, and chrome concentrate US$225 per tonne).

Stage 2 ramps production to 400,000 ounces per annum and is designed to be funded through cash generated from Stage 1 production, eliminating the need for additional external capital in the second phase. The Stage 2 development alone demonstrates a 26.4 percent internal rate of return using conservative PGM price estimates. The stage-1 all-in sustainable costs (AISC) are modelled at US$969 per 6E ounce, declining to US$821 per 6E ounce in stage-2 operations as the asset reaches steady-state production and benefits from full depreciation. The combined project net present value at 8 percent post-tax discount rate is US$857 million using the price deck assumptions. This staged development approach provides flexibility for equity and debt financing, allows proof-of-concept of mining and processing operations at reduced scale before full ramp-up, and manages execution risk through phased capital deployment.

Mineral Resource And Reserve Base Supports Long-Mine-Life Production Profile

Southern Palladium’s mineral resource base for Bengwenyama comprises 40.25 million ounces of combined measured, indicated, and inferred resources across both the UG2 and Merensky reef orebodies. This resource total was confirmed in a company update dated 23 October 2024 and included a 17 percent increase in the Merensky reef indicated resource to 2.23 million ounces (7E). The resource is hosted within large, high-quality UG2 and Merensky orebodies that are amenable to conventional underground mining methods employed across the Bushveld Complex. The company announced a maiden probable ore reserve of 6.29 million ounces at 6.17 grams per tonne (6E) comprising 31.72 million tonnes of ore, based on measured and indicated resources as confirmed in a company update dated 28 October 2024.

The reserve base is designed to support the staged production profile outlined in the development plan. At stage 1 production of 200,000 ounces per annum and stage 2 production of 400,000 ounces per annum (combined 600,000 ounces per annum at steady-state), the 6.29 million ounce reserve base provides approximately 10.5 years of operation, not accounting for mine reserve extension through systematic exploration during development. The mineral resource base of 40.25 million ounces substantially exceeds the current reserve, indicating significant conversion upside remains. This reserve and resource hierarchy is typical of early-stage development projects where measured and indicated resources are deliberately mined down through initial operations, with ongoing exploration converting inferred resources to indicated and measured categories. The scale and grade consistency of both the UG2 and Merensky orebodies support the technical feasibility of the proposed mining design and processing recovery assumptions.

Chrome As A Resilience Factor During Weak PGM Price Cycles

The strategic repositioning of Bengwenyama as a PGM-chrome co-product operation carries significant implications for project resilience during periods of PGM price weakness. Historically, PGM projects have been entirely dependent on platinum group metal pricing for economic viability. Southern Palladium’s asset, by contrast, will now generate approximately one-third of revenue from chrome concentrate sales at full production, diversifying the revenue base across two commodity price cycles. Chrome markets are driven by stainless steel demand, which is tethered to global infrastructure development, industrial capacity utilisation, and automobile production. PGM markets are driven by autocatalyst demand, jewellery, and industrial applications, responding to different macro drivers than chrome.

South Africa holds a strategically dominant position as the world’s leading chrome resource and producer, and chrome is an essential industrial mineral with no viable substitute in stainless steel production. Long-term demand for chrome is underpinned by global infrastructure development and industrialisation across emerging markets. By capturing 1.054 million tonnes per annum of chrome concentrate at 42 percent Cr₂O₃ (approximately 500,000 tonnes per annum of contained Cr₂O₃), Southern Palladium will participate in this structural growth dynamic. The announcement notes that increased chrome production can improve operating margins and strengthen overall project economics while providing greater revenue diversification. During periods when PGM prices are depressed, the co-product revenue stream from chrome sales can maintain overall project cash flows and project returns above break-even thresholds that would render a PGM-only asset uneconomical.

Outstanding Issues In Chrome Specification Will Determine Commercial Viability

While the metallurgical testwork demonstrates significant improvements in chromite recovery and PGM processing outcomes, the company has identified technical issues that must be resolved before final project development. The company notes that commercial Cr₂O₃ specification in the PGM concentrate remains an issue to be closed. Current laboratory values show Cr₂O₃ contamination in the PGM concentrate at 3.2 percent to 3.9 percent, but the company’s target is to reduce this below 2.5 percent Cr₂O₃. Elevated chrome contamination in the PGM concentrate could reduce the saleability of the final PGM product to refineries and smelters, which typically impose strict specifications on iron-group metal content in platinum group metal concentrates destined for precious metal recovery.

The technical work to reduce Cr₂O₃ levels below the 2.5 percent target threshold is expected to occur during the next phase of metallurgical testwork and mine design studies. The company did not disclose timelines for resolving this specification issue or alternative processing configurations that might achieve tighter chrome separation. The resolution of chrome specification issues is a material technical risk that will determine whether the co-product strategy can be executed as currently modelled. If chromite contamination cannot be reduced below commercially acceptable thresholds, the company may need to adjust the flotation circuit, modify grind sizes, or implement alternative chrome rejection methods, all of which could alter the recovery rates and operating costs currently projected in the definitive feasibility study.

Western Limb Opportunity Referenced But Not Detailed In Current Development Plan

The company update references exploration potential in the Western Limb of the Bushveld Complex but does not provide detailed commentary on this asset within the Bengwenyama development context. The Western Limb is noted as part of the broader exploration portfolio, but the current definitive feasibility study and staged development plan focus entirely on the Bengwenyama Project within the Eastern Limb. Southern Palladium’s announcement does not disclose whether Western Limb assets are held under exploration license, the status of any mineral resource estimation, or how these assets might be integrated into the company’s strategic development roadmap beyond Bengwenyama. Future company updates may provide greater clarity on the Western Limb opportunity and any role it plays in medium-term production or exploration growth beyond the Bengwenyama Stage 1 and Stage 2 ramp-up profile.

The focus of the Noosa Mining Investor Conference presentation on Bengwenyama repositioning suggests that Southern Palladium is concentrating capital and technical resources on bringing the Eastern Limb asset to development decision. This is a rational prioritisation for an early-stage development company, as advancing a tier-1 asset from prefeasibility through definitive feasibility and into funding and construction requires sustained technical and capital effort. The Western Limb reference indicates that the company holds additional exploration upside within its portfolio, which could provide value optionality if Bengwenyama development proceeds successfully and frees resources for regional exploration acceleration.

Next Milestones And Investor Focus Areas Following Noosa Conference Presentation

Southern Palladium has presented the Bengwenyama repositioning to the mining investor community at the Noosa Mining Investor Conference on 24 July 2026, marking a significant milestone in communicating the project’s evolved value proposition to institutional investors and development partners. The presentation of refined metallurgical testwork, staged development economics, and the PGM-chrome co-product repositioning provides potential funding partners, off-take customers, and joint venture partners with current information for investment decision-making and commercial negotiation. The conference presentation, combined with the attached slide deck covering exploration results, processing logic, and financial modelling, establishes a comprehensive information base for investor, creditor, and partner engagement.

Investors should watch for updates on the resolution of the Cr₂O₃ specification issues in the PGM concentrate and any refinements to the processing flowsheet that may result from ongoing testwork. The next key milestone is likely to be completion of the definitive feasibility study in its entirety, which would include updated capital cost estimates, construction timelines, mine design and sequencing, and final resource-to-reserve conversion studies. Following definitive feasibility study completion, Southern Palladium would typically move toward funding discussions with development partners, strategic investors, or debt providers, along with the negotiation of chrome and PGM off-take agreements with potential customers. The announcement does not provide guidance on timing for these milestones, but early-stage PGM development projects typically require 18 to 36 months from definitive feasibility study completion to construction commencement, depending on financing success and regulatory approval timelines.
