TORONTO, Dec. 20, 2024 (GLOBE NEWSWIRE) -- Giyani Metals Corp. (TSXV:EMM, GR:A2DUU8) ("Giyani" or the "Company"), developer of the K.Hill Battery-Grade Manganese Project in Botswana ("K.Hill" or “the Project”), is pleased to provide an update on the commissioning of the Demonstration Plant (“Demo Plant”) in Johannesburg.
Highlights:
The Demo Plant is nearing completion of commissioning, and the team continues to work determinedly towards first production of battery-grade high-purity manganese sulphate monohydrate (HPMSM) before year-end, but due to recent events, production may occur in early Q1 2025, due to the impact of the following:
Power outage from an isolated incident of vandalism and copper cable theft at an Eskom key point substation on December 11.
Water supply was consequently unavailable to the Demo Plant from December 12 to December 17.
Unexpectedly slow progress in commissioning the control system.
The power outage directly impacted the area of Krugersdorp, South Africa and additionally impacted the local water supply and thus the ability to run the Demo Plant. Water, which is critical for the commissioning process, was unavailable to the Demo Plant from December 12 to December 17, and this has impacted progress.
The water supply to the Demo Plant was reinstated midday on December 17, following which the operations team implemented a 24-hour recovery procedure to flush and clean the crystallisers after the extended stoppage.
One of the key objectives of the Demo Plant is to identify issues and improve the design, build and ramp-up of the Commercial Facility, which is planned for construction in Botswana adjacent to Giyani’s extensive, 100% owned manganese oxide ore sources.
Prior to commissioning and during the process, the team has implemented mitigating adjustments which have also impacted the timeline to production from the Demo Plant, including the unexpectedly slow progress in commissioning the control system, mentioned above.
The transition into full process flow hot commissioning and production remains imminent, now that full utilities, including power and water, have been restored to site. Demo Plant product samples will be provided to offtakers for qualification trials early in Q1 2025, enabling indicative terms in 2025.
Charles FitzRoy, President and CEO of the Company, commented:
“Giyani’s Demo Plant is progressing through the commissioning phase, and the team continues to work determinedly towards first production of battery-grade manganese. Whilst we are targeting first production of HPMSM this month, delivery in early Q1 2025 is likely. This is due to the recent unforeseen external impacts from power and water availability in Krugersdorp, South Africa, where the plant is located, in addition learnings identified and mitigations implemented as part of the normal commissioning process.
Whilst the disruption from power and water outage has now been resolved, the ongoing learnings will be leveraged for the construction of the main plant in Botswana; fine-tuning the process now will have demonstrable operational and cost benefits when we reach construction of the main Commercial Plant, and puts us on firmer footing for a successful and smooth ramp-up. These adjustments further endorse the strategic decision made to construct a Demo Plant at a 1:10 scale to the planned Commercial Facility, as this significantly de-risks the final Project.
The Demo Plant is an essential component in Giyani’s long-term strategy to deliver high-purity battery-grade manganese to the EV market. This production capacity establishes a strong foundation for Giyani to engage with potential offtake partners, as the continuous process flow of the Demo Plant will allow the team to target steady-state operations over extended periods, consequently proving Giyani’s ability to produce consistent battery-grade manganese and satisfy offtake requirements. This continuous operation at pre-commercial scale also provides critical information for understanding how the Commercial Plant will respond, further de-risking the Project.”

Power and Water Outage
The power outage impacted the local municipal water systems in the Krugersdorp region of South Africa where the Demo Plant is located. Whilst the power outage was rectified within 24 hours, the water outage had a more significant impact as multiple industrial and residential zones ran dry simultaneously. These events coincided with extended maintenance works on multiple water systems.
Whilst such incidents are not uncommon within the South African context, this is the first outage that has impacted the Demo Plant.
Water supply was reinstated on December 17.
Without water, commissioning work on site was restricted to areas where water could be recycled and reused. The boiler, which requires fresh water to generate steam, was temporarily shut down. This resulted in a delay of the C4 Hot Commissioning of the crystallisers which was underway at the time of the outage.
Demo Plant Construction and Commissioning Update
The construction of the Demo Plant, which consists of nine Process Modules (each a self-contained process system within a fixed frame) is largely complete. Full construction completion is due within the next week.
Since the news release (“NR”) dated November 14, 2024, commissioning continues apace. Various parts of the Demo Plant are now in the C4 phase, whilst other areas are C3 complete and waiting for first reagent delivery.
Whilst C4 commissioning is typically undertaken on a broader process level, Giyani saw an opportunity to pre-emptively work with the crystallisers in isolation and gain important information and learnings ahead of the availability of the full process flow.
The hot commissioning of the mill, leach, and impurity removal process areas is expected to commence following the delivery of first-fill reagents, which is imminent.
The filter presses used for various solid/liquid separation stages are progressing rapidly through C2 and C3 commissioning, and will be fully commissioned as soon as slurry is available from the upstream processes.

The Demo Plant laboratory, independently installed and operated by Quality Lab Services (QLS, a Minopex company) is nearing full operational capacity, with only the calcination furnaces yet to be completed. The key instrumentation of ICP-OES and XRF are both fully operational and the first sets of full analytical assays have been completed.
Stages of commissioning:
C1 – Full mechanical completion (individual Process Modules)
C2 – Dry testing, direction testing, loop testing (individual Process Modules)
C3 – Cold/Water Commissioning, software testing (individual Process Modules)
C4 – Hot Commissioning with reagents and steam (typically full Process)
C5 – Production Ramp-up (full Process)

In addition to progress at the Demo Plant, concurrent metallurgical test-work is underway to further optimize the flowsheet. Giyani is focused on further reducing reagent use and improving both the operating cost and carbon profiles for the Commercial Plant, planned for construction adjacent to Giyani’s extensive 100% owned manganese oxide ore sources in Southern Botswana.
The Demo Plant is designed at a scale factor of approximately 1:10 to the planned Commercial Plant. This provides robust and reliable scale-up from the Demo Plant data when the Commercial Plant is implemented. To illustrate, the leach tanks have a 60cm diameter in the Demo Plant and this is expected to be 8-10x larger at approximately 5m in the Commercial Plant.

Demo Plant Operational Overview
The development of all process plant standard operating procedures (“SOPs”) is complete and Minopex will continue to refine these procedures to ISO International Standards. As the Demo Plant is a direct copy of the anticipated Commercial Plant, at a 1:10 scale, the overall operating requirements and system requirements are very similar. Alongside the engineering, commercial and research benefits of the Demo Plant, the availability of mature SOPs will facilitate a smooth transition to full-scale commercial production.
The independent, fully ISO-certified laboratory will allow commercial-level metal accounting and provide rapid assay turnaround times to enable effective operation of the Demo Plant. The laboratory is near complete and is operational, with key equipment such as the ICP-OES and XRF already in active use.
The laboratory, and all the procedures and methods associated with it, can be transferred directly to the Commercial Plant, enabling a tried and tested laboratory set-up available on Day 1 of Commercial Plant commissioning.
