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.
