Demonstration Plant Construction Update

TORONTO, June 20, 2024 -- 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 announce an update on

construction at the Demonstration Plant (“Demo Plant ”).

Highlights:

• Construction at the Demo Plant in Johannesburg has been accelerating following completion and drawdown on the

US$26 million funding package (see April 24, 2024 news release).

• Demo Plant construction is progressing as planned, with key contractors mobilized and over 60 engineers and

technicians now active full-time at the site.

• The first two modular process skids (“Process Modules”) have been installed which have enabled the crystallizer units

to be fitted out with pumps and other components. The reagent make-up and water system Process Modules will be

moved into position shortly.

• Work is also continuing offsite at fabricator premises with the remaining Process Modules being assembled prior to

being transported and then installed at the demonstration plant.

• Simulation test work has commenced on the Yokogawa Distributed Control System (“ DCS”) software that will be used

to operate Giyani’s Demo Plant capable of continuously operating. The ability to continuously operate at this pre-

commercial scale will allow Giyani to understand how the Commercial Plant will respond ahead of construction, pre-

emptively staying ahead of anything that could arise during ramp-up.

• The Project remains on track for commissioning and production of battery-grade manganese (HPMSM), in Q4 2024 for

offtaker testing and qualification.

Process Module Installation

The Demo Plant will consist of nine Process Modules, each a self-contained process system within an easily transportable

frame. The first two Process Modules are shown in position below.

Danny Keating, President and CEO of the Company, commented:

“Following the drawdown of funds from the IDC in April, procurement and construction activities have accelerated rapidly. The

scale of the Demo Plant is exceptional and, once constructed, it will be one of the largest battery-grade manganese testing

and optimization facilities in the world. The value of this facility as a tool to optimize our proprietary flowsheet and reduce

operating costs will be immeasurable. The most important feature will be that we will now be able to provide offtakers with

tonnes of product for testing, rather than providing samples measured in grams. This level of production is not usually

available until commercial production is achieved, further de-risking the Project for our partners and potential financiers.

Successful construction and operation of the Demo Plant is a key catalyst to demonstrate the inherent value of the Project to

the market.”

Demo Plant Construction Update

The development of the Demo Plant is progressing with the main construction agreements for the civil, mechanical, electrical

and automation works having been signed and major contractors and sub-contractors mobilized to site. The 15m (45ft)

crystallizer units have already been installed (see Figure 2) and the supporting Process Modules are now also in place as

shown in Figure 1. Internal civil works have started to prepare the floor areas for further unit installations.

The Demo Plant construction process has been designed so that all parts follow a set order to aid construction and

commissioning, and in turn a speedy ramp-up to achieve on specification product for the offtaker process, commencing in Q4

of this year.

The Demo Plant is comprised of nine Process Modules which form the anchor for the entire Demo Plant construction. The

Demo Plant is a 1:10 engineering scale of the Commercial Plant, and 100m long as shown in Figure 3.

Installation of the main steam and ventilation systems has commenced, in advance of the next Process Modules. The detailed

construction program takes advantage of sequential mechanical, piping, electrical, and instrumentation installations to allow

the cold commissioning procedures to follow the sequence in a highly efficient manner.

Figure 4: Installation of Control Room Units and Preparation for Next Process Modules

The Process Modules in Figure 1 have enabled the crystallizer units to be fitted out with pumps and components, and the

peripheral equipment Process Modules for the crystallization process have been installed inside the plant in preparation for the

next Process Modules to be connected in a systematic way from that unit moving progressively towards the mill area.

The next Process Modules in the sequence (reagent make-up and water systems) will be moved into position shortly. These

will supply reagents and water through the process to achieve the final production of HPMSM to designed offtaker

specification.

Demo Plant Operations Update

Giyani has now commenced simulation test work on the Yokogawa DCS software that will be used to operate Giyani’s fully

continuous process facility. The ability to continuously operate at this pre-commercial scale will allow Giyani to understand

how the Commercial Plant will respond ahead of construction, minimizing issues that could arise during ramp-up. Unlike a lab-

or pilot-scale operation, a full, industrial control system is required to operate this large-scale, automated, hydrometallurgical

plant.

The development of all process standard operating procedures (“SOPs”) is well underway. As the Demo Plant is a duplicate of

the anticipated Commercial Plant, the overall operating requirements and system requirements are very similar. Alongside the

engineering, commercial and research benefits of the Demo Plant, the development of SOPs will assist in a smooth transition

to full-scale production.

Finalization of the design and contract for the on-site, independent, ISO-certified, hydrometallurgical laboratory is imminent.

This laboratory, which includes ICP-OES and XRF equipment, will allow full commercial-level metal accounting and provide

rapid assay turnaround times to enable effective operation of the Demo Plant.

About Giyani

Giyani is focussed on becoming the dominant western-world producer of sustainable, low carbon high purity battery grade

manganese for the electric vehicle (“ EV”) industry. The Company has developed a proprietary hydrometallurgical process to

produce High Purity Manganese Sulphate Monohydrate (“ HPMSM”), a lithium-ion battery (“LIB”) cathode precursor material

critical for EVs.

The Company has secured US$26m in financing from two strategic partners, ARCH Sustainable Resources Fund LP and the

Industrial Development Corporation of South Africa, as it aims to progress the K.Hill battery-grade manganese project in

Botswana to construction by building and operating the Demo Plant and completing a Definitive Feasibility Study by H1 2025.
