Prefeasibility Study advancing with +30,000m drilling completed


• To date over 30,000m of diamond drilling has been completed, consisting of 79 mother holes and 48

• Recent drilling has targeted the North Horst Block to get a better understanding of that area for the
  forthcoming PFS and potentially convert more of the Inferred resource to Indicated status.

• Results for the final drill holes will be incorporated into an updated Mineral Resource estimate, which
  is scheduled for completion in early Q3 CY2024.

• Updated Mineral Resource estimate and maiden reserve will form part of the Prefeasibility Study (PFS)
  which is scheduled for completion early Q4 CY2024.

• SRK Consulting has been commissioned to review ongoing PFS work to ensure the highest standards of
  due diligence and quality assurance.

• Environmental Impact Assessment (EIA) remains underway and is advancing on schedule, with
  submission slated for mid-2024.

• SPD remains well funded to complete the PFS from existing cash reserves, with a cash position of
  $8.34m as at December 31, 2023.

Southern Palladium (ASX:SPD and JSE:SDL), 'Southern Palladium' or 'the Company') is pleased to provide
an update on development works that will be incorporated into the forthcoming Pre-Feasibility Study (PFS)
for the Company's Bengwenyama Platinum Group Metal (PGM) project, on the Eastern Limb of the world
class Bushveld Complex, South Africa. Notably, it is strategically positioned in the heart of a significant
underground mining region, leveraging existing infrastructure and knowledge for operations. An extensive
Scoping Study for Bengwenyama by Johannesburg-based mining consultancy Minxcon (Pty) Ltd earlier this
year (refer ASX Announcement 1 February 2024) confirmed the continuation of the PFS.

A summary of key results from the Scoping Study are set out below:

• Life of Mine (LOM) on the UG2 reef only is estimated at 36 years for an average annual production rate
  of 330 Koz PGM (6E basis) with cash costs firmly at the low end of the global cost curve.

• Development of a shallow underground mining operation targeting the ~2 Mtpa UG2 reef via decline
  systems, employing a hybrid mining method commonly utilised in neighbouring mines.

• The mill feed is characterized by a head grade of 6.55g/t (7E). Processing will involve conventional
  flotation and spiral plant techniques to produce a marketable PGM concentrate with an anticipated
  recovery rate of approximately 85% for the major metals. Additionally, a chrome concentrate will be
  produced for sale in export markets.

• Initial capital spend of ~US$408m.

• Post-tax NPV of ~USD700 million based on conservative commodity price assumptions (Pt US$1200/oz,
  Pd US$1100/oz, Rh US$5000/oz).                                                                                                   

• Post-tax IRR of ~21% with post-tax capital payback of ~4.5 years from first concentrate production.

• Life of mine EBITDA totalling ~US$5.2 billion.

Managing Director Johan Odendaal, said: 'With over 30,000m of drilling completed, we are now
transitioning towards the completion of a PFS. Notably, the initial target area in Eerstegeluk has been
successfully converted to Indicated Mineral Resources by the end of 2023, marking significant progress. With
assay results for the North Horst Block still pending, the project already boasts an existing Indicated and
Inferred Mineral Resource Estimate of 26.22Moz (6PGE+Au). To ensure the utmost standards of due diligence,
the Company enlisted SRK Consulting to conduct a comprehensive review of our ongoing work, fostering
transparency and independence in the project development process. SPD remains well-funded to see the PFS
through to completion early in the fourth quarter of 2024. The Environmental Impact Assessment, a core
component of the forthcoming Mining Right application, is also progressing well and remains on schedule to
be submitted for review by mid-2024.'

PFS Update

Drill programme

To date over 30,000m of diamond drilling has been completed, consisting of 79 mother holes and 48
deflections, 12 boreholes and 19 deflection more since the resource was updated in December. As the PFS
exploration phase comes to an end, the main activities at the Bengwenyama project have now moved to the
completion of the PFS and the Environmental Impact Assessment as part of the Company's forthcoming
Environmental Impact Report (EIR) submission for the granting of the Mining Right.

The initial target area in the shallow portion of Eerstegeluk has been successfully converted to Indicated
Mineral Resources by the end of CY2023. The recent drilling has targeted the North Horst Block to get a better
understanding of that area for the forthcoming PFS and potentially convert more of the Inferred resource to
Indicated status.

The final assays will be submitted in April, with the receipt of all assays then expected by the end of May. The
resource already contains an Indicated and Inferred Mineral Resource Estimate of 26.22Moz (6PGE+Au) (refer
ASX Announcement 7 December 2023).

Following receipt of all assays, an updated Mineral Resource estimate – integrating the findings from the final
holes drilled for the PFS phase – is scheduled for completion early in the September quarter.


Concurrent with the completion of the PFS drill program, comprehensive metallurgical and geotechnical test
work remains ongoing. Additional test work has been designed to increase confidence in the metallurgy
process flowsheet and make improvements to both recovery and grade of the 7E PGM content from the UG2

Preliminary testing indicated that the Bengwenyama UG2 Reef can be treated using conventional methods,
and initial test works showed outstanding metallurgical recoveries of between 85% and 80% with
concentrate grades of 130 to 250g/t (4E) can be obtained (refer ASX Announcement 6 December 2023).


The Scoping Study identified that there is a well-established downstream smelting and refining process for
PGM concentrates within South Africa. Well-established precedents exist for commercial terms that would
be applicable for UG2 and Merensky concentrates. Most smelters processing the concentrate from the
Eastern and Western Limbs are situated in Rustenburg, with almost all the concentrator product in the area
being transported by truck to Rustenburg. The Project PGM concentrates are believed to be suitable for these
facilities. The recently completed Scoping Study enables the company to initiate discussions with potential
offtake parties.

Community engagement

Southern Palladium continues to maintain strong engagement with the Bengwenyama community through
direct consultation and inclusion initiatives.

Alongside ongoing drill works and project development, weekly exploration meetings are held with
representatives of the Community along with Minxcon Pty Ltd, the environmental and exploration
management consulting firm contracted to the project. Quarterly meetings are also held with extended
representation from the greater Royal Family, Traditional Council and community representatives.

Environmental Impact Assessment

The acceptance letter for the Mining Right Application, received on 17 October 2023 marked the
commencement of the Environmental Authorisation process comprising the Scoping and Environmental
Impact Assessment (EIA) reporting phases. The scoping phase was concluded with the receipt of the
acceptance letter on 15 February 2024, initiating the subsequent EIA phase.

This process entails ongoing consultation with local authorities and engagement with interested and affected
parties. It also involves conducting specialist studies by independent experts and the eventual compilation of
the comprehensive Environmental Impact Report (EIR) by the independent environmental consultancy, OMI
Solutions (Pty) Ltd. This report will delineate all biophysical and socio-economic impacts, along with proposed
mitigation measures and the Environmental Management Programme (EMPR). The final EIR, encompassing
all findings and the EMPR, is anticipated to be submitted to the Department of Mineral Resources and Energy
(DMRE) for review by mid-2024.

SRK Review of the PFS
To ensure the highest standards of due diligence and quality assurance throughout the project lifecycle, SPD
has enlisted SRK Consulting (South Africa) (Pty) Ltd (SRK) to conduct a comprehensive assessment and review
of the ongoing work pertaining to the Mineral Resource estimation and Pre-Feasibility Study (PFS).

The review process entails interactive sessions between various SRK discipline consultants and
representatives of Minxcon Pty Ltd, which is conducting the PFS, to ensure the early identification of potential
challenges that may impact the final PFS outcome.

Funding of the PFS

Southern Palladium remains well funded to complete the PFS, with A$8.34 million in cash as at 31 December
2023 (refer ASX Announcement 29 February 2024). Consistent with previous guidance, the PFS is expected to
be completed early in the December quarter.

This announcement has been approved for release by the Board of Southern Palladium Limited.
