Completion of Successful PFS Drilling Campaign
Highlights:
• Initial resource drilling campaign for the PFS has now been completed and all assays have been
received.
• A total of 82 drillholes were completed totalling 30,746m - including 50 reef deflections.
• Drilling results for the UG2 reef, with a weighted average 7E grade of 9.88 g/t over 67cm, have
consistently confirmed the initial Inferred Mineral Resource grades and prill split – thus confirming
the robustness of the UG2 Reef and the broader project.
• Additional samples have been collected for metallurgical test work to confirm the recovery of by-
product chromite from the UG2 Reef.
• Footwall mineralisation of the Merensky Reef (MR) has been observed, which is now being
investigated further.
• An updated Mineral Resource Estimate (MRE) will be released in Q3 CY2024 which will facilitate the
commencement of mine planning for the Pre-Feasibility Study (PFS).
Southern Palladium (ASX:SPD and JSE:SDL), 'Southern Palladium' or 'the Company') is pleased to
announce the successful completion of the initial resource drilling campaign for the PFS for the
Bengwenyama Platinum Group Metal (PGM) project, located on the Eastern Limb of the world class
Bushveld Complex, South Africa.
Managing Director Johan Odendaal, said: "We are pleased with the consistency of recent drilling results
to the initial inferred Mineral Resource grades and prill split, which underscores the robustness of the UG2
Reef and the overall project. The completion of 82 drillholes, totalling 30,746 meters, including 50 reef
deflections, marks a significant milestone in our exploration efforts. These results provide a strong
foundation for the upcoming Mineral Resource update and the ongoing PFS. The metallurgical test work
on chromite recovery and the investigation of mineralisation in the footwall of the Merensky Reef will
further enhance our understanding of the resource potential. We remain committed to advancing the
Bengwenyama project, leveraging our experienced management team and strategic positioning in the
global PGM market. The forthcoming updates and continued drilling for the Definitive Feasibility Study
(DFS) will be crucial in realising the full potential of this world-class asset."
Completion of the Initial Drilling Campaign
The initial drilling campaign aimed at declaring Indicated Mineral Resources for the PFS was completed
successfully during Q2 2024. This will provide the basis for an Indicated Mineral Resource in Q3 CY2024
of sufficient size and quality to allow the completion of a PFS for the Bengwenyama project. All samples
submitted to ALS laboratories in Johannesburg have been received back from the laboratory, allowing for
the next MRE to commence.
In total 82 drillholes have been completed, totalling 30,746m which included 50 reef deflections. These
reef deflections were drilled for metallurgical sample collection, and some will be utilised to study the
short-range variability (SRV) of the UG2 reef for resource estimation purposes.
In addition to this, two of the deflections were used for mineralogical studies that were completed by
Suntech Geomet laboratories in Johannesburg. Figure 1, below, shows the collar positions of the drillholes
completed as well as the historical drillholes that were used to construct the initial geological model and
Mineral Resource estimate. The drilling for the PFS was focused on the eastern portion of the farm
Eerstegeluk to achieve Indicated Mineral Resources in the shallower portion (between 30m and 400m
below surface with an average depth of ~ 275m) of the UG2 reef. The drill spacing here is between ~200m
and 700m with an average spacing of ~350m.
The drilling campaign continues to confirm the average grade and prill split of the UG2 Reef. The final
weighted average for the representative UG2 intersections is a reef with of 67 cm at an average grade of
8.25 g/t 3PGE + Au (4E) and 9.88 g/t 6PGE + Au (7E). The prill split of the weighted average of the
representative intersections for the 3PGE + Au is Pt:Pd:Rh:Au of 44.5% : 45% : 9.1% : 1.4% (Table 1). These
results are in line with expectations.
Drilling has also been completed in the North, Central and Southern Horst Blocks to develop the geological
understanding of the area to the west of the current core Bengwenyama resource. The drilling in the
Northern Horst Block confirmed both the MR and UG2 in the area. However, the drilling completed in the
Central and Southern horst block confirmed that there is limited potential on the UG2 and these areas are
unlikely be converted to Mineral Resources. (These zones were previously included as an Exploration
Target). This appears to have little or no impact on mine planning for the PFS.
Separately, results for the MR exhibited some potential for these areas to be converted to Mineral
Resources. The remaining exploration targets for both the MR and the UG2 on the farm Nooitverwacht
(to the west) have also been assessed to have good upside potential to be converted to Mineral Resources.
A geological structural plan is being updated with the new data and the MRE will follow in Q3 2024.

Mineralisation in the Merensky Footwall
The recent drilling has also highlighted areas of additional potential mineralisation in the footwall of the
MR. Based on this, the company is reviewing the MR intersections and footwall to better understand the
extent of this footwall mineralisation. Ongoing exploration will include additional sampling further into
the footwall to investigate this opportunity. The additional MR results will be released at a later stage
when assays are available.

This announcement has been approved for release by the Board of Southern Palladium Limited.
About Southern Palladium:
Southern Palladium Limited (ASX:SPD, JSE:SDL) is a dual-listed platinum group metal (PGM) company
developing the advanced Bengwenyama PGM project, particularly rich in palladium/rhodium, in South
Africa. The project is located on the Eastern Limb of the Bushveld Complex, which contains more than
70% of the world's known Platinum Group Metal (PGM) Resources.
The Company, holding a 70% stake in the project, will primarily concentrate on delivering a Pre-
Feasibility study. Additionally, following the completion of a geophysical survey conducted in 2022 and
the September 2023 submission of the Mining Right application, they will oversee the completion of
the diamond drill programme initiated in August 2022, along with several other concurrent technical
studies.
Bengwenyama presents a substantial opportunity in the global PGM market. Previous exploration
efforts have already yielded a JORC 2012-compliant Inferred Mineral Resource of 25.12Moz within two
ore horizons—the UG2 chromitite and Merensky Reef, achieved in 2023.
Moreover, an assessment conducted by mining industry consultants CSA Global in 2021, has identified
a significant exploration target beyond the currently explored area. The Company is led by a seasoned
on-ground management team, including some of South Africa's most distinguished mining industry
executives.
Competent Person Statement
1. Uwe Engelmann: The scientific and technical information contained in this announcement has been
