Giyani Produces High Purity Manganese

Sulphate Monohydrate from Demo Plant

TORONTO

,

Oct. 6, 2025

/CNW/ - 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 it has successfully produced High Purity Manganese

Sulphate Monohydrate ("

HPMSM

") from its Demonstration Plant (

"Demo Plant"

) in

Johannesburg,

South Africa

in

September 2025

.

Highlights:

Successful production of HPMSM from the Demo Plant in

Johannesburg, South Africa

, marking

a significant milestone for the Company.

HPMSM off-taker qualification trials will now commence.

Following the successful production of High Purity Manganese Oxide ("

HPMO

") in Q1 2025,

Giyani has now proven its dual product offering capability which positions the Company to

supply its products to a broad range of potential future battery technologies and keep pace with

the rapidly evolving battery market.

Giyani's Demo Plant has provided invaluable information and has derisked the final optimized

process flowsheet which will now be carried forward into the design and operation of the full-

scale commercial plant in

Botswana

.

Outlook:

The Company's focus over the next six months will now be:

To complete the Definitive Feasibility Study ("

DFS

") to NI 43-101 standards. This remains on

track for completion by end Q1 2026.

Ongoing qualification of Giyani's HPMSM and HPMO product.

Nigel Robinson

,

Interim Executive Chair

of the Company, commented:

"Achieving first production of HPMSM in Q3 2025 represents a significant milestone for the

Company. The Demo Plant has been invaluable in informing the new optimized process flowsheet,

developed by Giyani, over the past several months.

We will now incorporate the learning points and process changes into the DFS which remains on

track for completion in Q1 2026. This significant milestone will also allow us to commence the off-

taker testing phase for HPMSM with HPMO qualification already well underway.

"With the successful production of both HPMSM and HPMO, we have demonstrated our dual

product offering capability, placing us in a strong position to supply the dynamic and evolving

chemical requirements of the battery and energy storage market. I would like to take this

opportunity to thank all the team for their dedication and hard work in achieving this milestone.

Production of HPMSM from Demo Plant

The Company has successfully produced HPMSM from its Demo Plant in

South Africa

. First product

will now be shipped to potential off-takers for initial qualification. The Demo Plant has been an

invaluable asset in developing Giyani's new innovative process flowsheet. The Demo Plant assisted

in the risk identification and mitigation of process risks and has unquestionably enhanced the

commercial viability of the K.Hill Project. The Demo Plant has provided the Company with significant

information which will be carried forward to the design and operation of the full-scale commercial

plant in

Botswana

.

Manganese Market

The demand for manganese is set to rise significantly, driven by advancements in battery

technologies that increasingly favour higher manganese content owing to its stabilizing properties.

From 2028 onwards, new battery chemistries being developed will require greater quantities of

battery-grade manganese as critical inputs. This shift in demand is largely attributed to the growing

adoption of electric vehicles and energy storage solutions, both of which rely on next-generation

batteries with enhanced performance and safety profiles. Giyani is uniquely positioned to capitalize

on this market evolution. The Company benefits from assets located in a supportive jurisdiction,

enabling it to align its project timelines with the anticipated surge in demand for battery-grade

manganese.

About Giyani

Giyani is focused on becoming the preferred western-world producer of sustainable, low-carbon

high-purity battery-grade manganese for the EV and ESS industry. The Company has developed a

bespoke hydrometallurgical process to produce battery-grade manganese products, for cathode

precursor materials, critical for EVs and ESS.
