FIREBIRD’S ENERGY SAVING ROTARY KILN SUCCESSFULLY TESTS
LOW GRADE MANGANESE ORE FOR EUROPEAN SULPHATE
PRODUCER, REDUCING ENERGY USE BY >50%
HIGHLIGHTS
•
Firebird has successfully completed calcining and leaching trials, for Taza Metal
Technologies (Taza), an established manganese chemical business based in
Kazakhstan, who supplies the European market
•
Taza, seeking to utilize stockpiles of lower-grade manganese ore (18–20% Mn) for
high-purity manganese sulfate (HPMSM) production, engaged the Firebird technical
team for support
•
Taza is seeking to procure manganese chemical processing equipment, including a
calcining kiln, from China. Trial work with Firebird forms a critical component of
their due diligence in assessing potential supply partners
•
Trial work was based on 3.3 tonne manganese ore sample received from Taza and
Taza has covered all costs associated with completing the test work
•
Results demonstrated a significant energy reduction, with average consumption of
230 kWh per tonne of ore feed (which includes drying and kiln pre-heating),
compared to greater than 400 kWh/t quoted for conventional rotary kilns by thirdparty suppliers. On a commercial-scale kiln, a further 25% reduction is expected—
bringing total consumption to less than half
•
Energy saving results complement previous tests on high grade ore where 70%
energy saving was achieved, technology works on all ore types
•
Firebird’s calcining technology has broad industrial applications, as many chemical
processes containing a calcining kiln, such as lithium spodumene processing
•
Firebird is currently handling several kiln inquiries from both within China and
internationally
Firebird Managing Director, Mr Peter Allen, commented:
“This trial work further demonstrates and validates clear industry demand for our innovative calcining
kiln. Our kiln delivers energy savings that are crucial to the minerals processing industry – making this
product potentially transformative for the market, and for our Company.
“Our technical team is continuing to deliver consistent innovation that makes our own processes more
efficient, supporting our low-cost LMFP battery cathode strategy, and affords us the opportunity to
commercialise revolutionary new technology. Our commitment to efficiency, alongside our highquality in-country partners, gives us the opportunity to become one of the lowest-cost battery-grade
MnSO4 producers, placing us in an incredibly competitive market position going forward.”

Australian-owned Firebird Metals Limited (ASX:FRB, Firebird or the Company) is pleased to
announce it has successfully completed calcining and leaching test work for Taza Metal
Technologies (Taza) which is a part of ongoing technical due diligence of Firebird’s energyefficient calcining kiln for Taza’s manganese chemical production.
Firebird’s Chinese subsidiary, Hunan Firebird Battery Technology (HFBT), has processed 3.3
tonnes of 18-20% manganese ore from lower-grade stockpiles from Taza’s mine in Kazakhstan
using the Company’s pilot scale calcining kiln, reducing the manganese ore to manganese
monoxide (MnO). Taza has covered all costs associated with completing the test work.
This is another significant step in the Company’s strategy to commercialise its innovative, efficient
technology globally, and validates the quality of Firebird’s calcining kiln.
The trial demonstrated significant energy reduction, 230 kW/t (including energy consumption
during startup and preheating) achieved against quoted 400 + kW/t for conventional rotary kilns
from third party suppliers. On a commercial-scale kiln, a further 25% reduction is expected—
bringing total consumption to less than half.

The average manganese leaching rate was around 95%, indicating high leaching efficiency and
low manganese residue. The average residual manganese content in the acid leaching residue
was approximately 1.5%.

Taza Metal Technologies, a Kazakhstan-based manganese mining and chemical processing
company, is seeking to utilize stockpiles of lower-grade manganese ore (18–20% Mn) for highpurity manganese sulfate (HPMSM) production.
Taza is actively pursuing the procurement of manganese chemical processing equipment from
China, including a calcining kiln, as part of its strategy to expand high-purity manganese sulphate
(HPMSM) production. As a key component of its due diligence process, Taza has re-engaged
Firebird’s technical team, following previous successful collaboration, to undertake test work.
These trials are designed to evaluate the performance, efficiency, and operational suitability of the
proposed equipment under real-world conditions, providing critical technical validation to support
Taza’s procurement decisions.

Firebird’s Energy Efficient Calcining Kiln
Firebird’s calcining kiln, currently under international patent application, provides significantly
greater energy efficiency than existing alternatives. Firebird has successfully completed trials of
the pilot scale calcining kiln, with remarkable results generated – indicating that the calcining kiln
has the potential to reduce energy usage by 70%1 when processing 44% manganese content ore.
Compared to conventional kilns, which typically require more than 300kWh per tonne of 44%
Manganese ore feed, FRB’s pilot kiln operates at only 80-100kWh per tonne – translating to a
significant cost reduction of USD30 per tonne of product, or approximately 5% of total production
costs2.
The calcining kiln technology is highly scalable, works on all ore types and, in addition to
applications in manganese-related mineral processing, will also be assessed for use across
industries such as iron ore beneficiation and lithium sulphate production.
The Company is currently managing multiple kiln inquiries from both within China and
international potential clients.
This announcement has been approved for release by the Board.

About Firebird Metals Limited
Firebird Metals is an advanced manganese developer focused on combining mining and
downstream processing with a dedication to the advancement of the EV battery sector.
The Company is currently progressing its unique China-focused lithium manganese iron
phosphate (LMFP) battery strategy, which will develop Firebird into a near-term producer of highpurity, battery-grade manganese sulphate, a key cathode material in LMFP batteries for electric
vehicles.
Execution of this strategy will place Firebird at the forefront of manganese sulphate production,
at a time when the use and demand for manganese in batteries continues to rapidly grow. Due to
the low number of ASX-manganese developers and increasing use of LMFP by car manufacturers,
Firebird considers that it is in a strong position to benefit from this growing market and deliver
significant value to its shareholder base.
The Company also owns 100% of its project portfolio, located in the renowned East Pilbara
manganese province of Western Australia, which boasts a total Resource of 234Mt3,4, with exciting
exploration and development growth upside. The portfolio is led by the flagship Oakover Project,
which holds a Mineral Resource Estimate 1 of 176.7 Mt at 9.9% Mn, with 105.8 Mt at 10.1% Mn in
an Indicated category.
The Company is committed to generating sustainable long-term value and growth for
stakeholders, through the implementation of best practice exploration methods while prioritising
the well-being, health and environmental protection of its employees and communities it operates
in.
