PAN AFRICAN SUCCESSFULLY CONCLUDES MINTAILS’ MOGALE GOLD DEFINITIVE FEASIBILITY STUDY (“DFS”)
Pan African is pleased to announce that the Company has successfully completed a DFS on the Mogale Gold Proprietary Limited (“Mogale Gold”) Tailings Storage Facilities (“TSFs”) that forms part of the Mintails Mining SA (Proprietary) Limited (“Mintails SA”) assets, situated near Krugersdorp to the west of Johannesburg, South Africa (the “Project”). The DFS was prepared by DRA Projects SA (Pty) Ltd (“DRA”), with reliance on specialist input from third parties for Mineral Resource and Mineral Reserve estimation, dump re-mining, tailings pumping and disposal and metallurgical test work. The parties have provided their consent for the release of the information contained in this announcement as far as it pertains to the results of the DFS.
HIGHLIGHTS FROM DFS
Cobus Loots, CEO of Pan African, commented: “Pan African has an excellent track record of successfully commissioning and operating surface tailings retreatment operations, as evidenced by our BTRP, ETRP and Elikhulu operations. As originally anticipated, the Mogale Gold DFS has demonstrated a compelling Project, both operationally and financially. Mintails has the potential to further improve the Group’s overall AISC, while increased annual production will move Pan African further up the ranks of mid-tier gold producers.
Additionally, our re-mining activities will assist with environmental remediation in this area. We look forward to working with all stakeholders to further progress the Project in the months ahead.”
Background to the Project
In November 2020, Pan African announced that the Company had entered into conditional sale of shares agreements to acquire the share capital and associated shareholder loans and other claims of Mogale Gold and Mintails’ SA Soweto Cluster Proprietary Limited (“MSC”) (together the “Mintails Transaction”). Both Mogale Gold and MSC are 100% owned by Mintails SA, which was placed into provisional liquidation during 2018.
The deadline for fulfilment of the conditions to conclude the Mintails Transaction was extended to August 2022 and included the completion of a fatal flaw analysis, prefeasibility study (“PFS”) and DFS. The PFS on the Mogale Gold TSFs was completed during July 2021, followed by the DFS, announced today. Both studies were led by DRA. Further technical work on the MSC TSFs is currently in progress.
Mineral Reserves and Resources
Following the initial due diligence on Mogale Gold, the following work was undertaken to improve the Mineral Resource confidence:
The combined drilling totaled 2,761m resulting in 1,877 samples and 187 control samples; and resulted in the remodeling of all available resources as reported in the Mineral Resource table below:
Indicated and Inferred
| TSF | Tonnage Mt |
Gold | ||
| g/t | kg | oz | ||
| Indicated | ||||
| Total Indicated | 121.62 | 0.29 | 35,049 | 1,126,855 |
| Inferred | ||||
| Total Inferred | 4.64 | 0.33 | 1,525 | 49,040 |
The updated three-dimensional Mineral Resource models were subjected to a hydro-mining and load-and-haul mine design and schedule according to engineering parameters as defined in the DFS. The same approach was previously used by Pan African during the design process of the Group’s Elikhulu operation (Elikhulu).
Scheduling of the available resources was built around achieving a throughput rate of 800ktpm, as detailed in the July 2021 PFS, as the optimal processing throughput. The Mineral Resources subjected to the mine design and scheduling was subsequently converted to Probable Mineral Reserves, as depicted in the table below:
Mineral Reserves
Probable Reserves |
Tonnage | Gold | ||
| Mt | g/t | kg | oz | |
| Total Mineral Reserves | 123.58 | 0.29 | 35,400 | 1,140,180 |
Conceptual MSC resource/reserve and production upside
In the SENS announcement of 6 November 2020, the Company reported that the MSC TSFs comprise nine separate facilities with resources of 119Mt with an in-situ grade of 0.31g/t, containing an estimated gold content of 1.20Moz. Although Pan African currently classifies the MSC Mineral Resources in the Inferred Mineral Resource category until further technical studies and work is completed, a conceptual production schedule for this project was applied, based on available information.
This conceptual production scheduling, entailing the processing of combined TSFs demonstrates a more robust recovered ounce profile and an extended LOM for the project, in excess of 20 years. The conceptual MSC TSF model increased production by an average of 11koz/yr from years 6 to 13 (once the Mogale Gold TSF resources are depleted), giving rise to a production profile of an average 54koz/yr from year 14 to 20.
No Mineral Reserves or financial valuation for the conceptual MSC scheduling can be reported on at this stage and the incremental production from this cluster is included for illustrative purposes only.
Re-mining and processing
The study envisages hydro-mining to be utilised for the larger dumps, using hydraulic guns of similar specification as used at Elikhulu, cutting mine widths of 15m wide and 20m deep. The North Sands and South Sands dumps are conducive to load-and-haul mining, to extract the resources from these dams.
The re-mined tailings will be processed in a CIL plant of similar design to the Elikhulu operation, with the addition of a water treatment section to limit corrosion and potentially improve recoveries. The DFS process plant is designed for an average throughput of 800ktpm, with up to 900ktpm achievable without negatively affecting performance.
All of the borehole samples were utilised to refine and test the expected gold recoveries from the processed material, under the direct supervision and management of Pan African. The modelled recoveries are presented in the table below:
| Resource material TSF | % Recovery modelled |
| 1L23-25 | 54.70% |
| 1L13-15 | 48.90% |
| 1L28 | 34.40% |
| 1L8 | 53.56% |
| 1L10 | 50.85% |
| North Sand Dump | 71.00% |
| South Sand Dump | 75.71% |

ESG/Social Impact
As part of the DFS, the Company has already conducted extensive engagements with community representatives and other interested and affected organisations based in the area, including regulatory authorities. This information and the EMPR is being utilised to compile an action plan to remediate past environmental damage and restore the surface for productive land use, while at the same time investigating impactful socio-economic development projects intended to stimulate the local economy.
The Company will also conduct feasibility studies into the merits of renewable energy for the new tailings retreatment plant’s energy requirements.
