Giyani Produces First Battery-Grade Manganese at its Demo Plant

TORONTO, March 03, 2025 -- 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 that High Purity

Manganese Oxide (“HPMO”) has been produced at the Demonstration Plant (“Demo Plant ”) in Johannesburg.

Highlights:

• A key milestone was achieved during February with the production of HPMO, a precursor for the production of High

Purity Manganese Sulphate Monohydrate (“HPMSM”), and also a precursor for certain electric vehicle (“EV”) and energy

storage system (“ESS”) batteries. HPMO samples are expected to be shipped in March to prospective offtake partners.

• HPMO is becoming the preferred precursor for the rapidly growing market for Lithium-Manganese-Iron-Phosphate

(“LMFP”) and Lithium-Manganese-Nickel-Oxide (“ LMNO”) EV and ESS batteries. Whilst HPMSM is the preferred

precursor for Nickel-Manganese-Cobalt (“ NMC”) EV and ESS batteries, HPMO and HPMSM can both be used to

produce LMFP and LMNO batteries.

• Giyani has received indications of demand for HPMO from OEM groups, and intends to produce both HPMO and

HPMSM in order to give the Company technological and product optionality, enabling it to maintain pace with the

rapidly developing battery market, and be able to serve the majority of potential future battery types.

• The Demo Plant remains on track to produce HPMSM during Q1 2025. Samples of HPMSM will then be provided to

potential offtakers to begin qualification trials as part of the offtake process, which will form an integral component of

Project Financing.

• The Demo Plant’s secondary objective is to significantly derisk the Commercial Plant (to be constructed in Botswana)

design in parallel with the Definitive Feasibility Study (“DFS”) which is underway and expected to be completed in 2025.

• The Giyani team is attending the PDAC conference in Toronto this week, with a full schedule of offtaker, investor, and

strategic meetings.

Charles FitzRoy, President and CEO of the Company, commented:

“Production of HPMO from the Demo Plant is a huge milestone. It proves the flowsheet at this precommercial scale, confirms

Giyani’s technological optionality to be able to serve the rapidly evolving battery industry, and diversifies Giyani’s product risk.

A fantastic achievement from all the team and now onto the next step of producing HPMSM which is anticipated in Q1 2025.

The commercial advantages of producing multiple battery-grade manganese products cannot be overstated. The battery

market is moving exponentially quickly, and the dual capability of being able to produce both HPMO and HPMSM allows

Giyani to position itself as a preferred supplier in this fast paced industry. LMFP battery demand is increasing and will likely

take a large market share from LFP batteries, and in-turn will increase demand for battery-grade manganese in both HPMSM

and HPMO form.”

Demo Plant Commissioning and Production Update

The construction of the Demo Plant, which consists of nine Process Modules (each a self-contained process system within a

fixed frame), is complete. The Production ramp-up (C5 Commissioning) phase has advanced, and the team continues to work

determinedly towards first production of HPMSM. The Demo Plant materially advanced Hot Commissioning (C4

Commissioning) during February 2025. C4 and C5 commissioning naturally progress in parallel in the final stages of

commissioning.

Commissioning challenges have included power outages, water supply disruptions, engineering and technical challenges, the

majority of which were expected and mitigated during February 2025.

The Demo Plant also enables final optimization of the engineering design and flowsheet to reduce operating costs and carbon

profile, in parallel with the DFS which is underway and expected to be completed in 2025. The Demo Plant laboratory,

independently installed and operated by Quality Lab Services (QLS, a Minopex company), continues to operate as planned

with full analytical surveys completed during the ordinary course of operations.

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.

Alongside the engineering, commercial and research benefits of the Demo Plant, the availability of mature Standard Operating

Procedures (“SOPs”) will facilitate a smooth transition to full-scale commercial production.

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.

Botswana Developments

Giyani announced in January (see NR dated January 23, 2025) the receipt of its Special Economic Zone (“SEZ”) licence for its

Commercial Plant. The SEZ licence will positively impact the Company, as it provides fiscal and non-fiscal benefits. Important

to note is that the Company will benefit from 5% corporate tax rate for the first 10 years of production from its Commercial

Plant, increasing to 10% thereafter, a considerable benefit which was not included in the 2023 PEA.

During February, Giyani launched its first tender for site preparation works, exclusively reserved for 100% Botswanan citizen-

owned companies. The tender for perimeter fencing and beacon installation is targeting contractors from Kanye, ensuring the

local community directly benefits from Giyani’s project.

About Giyani

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

manganese for the EV and ESS industry. The Company has developed a proprietary hydrometallurgical process to produce

battery-grade manganese (HPMSM and HPMO), a lithium-ion battery cathode precursor material critical for EVs and ESS.
