FRB SUCCESSFULLY TESTS ENERGY-EFFICIENT ROTARY KILN
70% REDUCTION IN ENERGY CONSUMPTION
HIGHLIGHTS
•
Following extensive internal trials and independent reports from Sunward, FRB’s
self-developed electrical rotary kiln has demonstrated remarkable energy savings.
The kiln, currently under patent application, showcases a groundbreaking reduction
in energy consumption
•
Compared to conventional kilns, which typically require more than 300 kWh1 per
tonne of feed, FRB’s pilot kiln operates at only 80-100 kWh per tonne — delivering an
impressive 70% energy savings. This translates to a cost reduction of USD30 per
tonne of product, or 5% of total production costs2
•
Kiln design is highly scalable, with expectations for further energy savings as it
moves from pilot to full-scale production due to economies of scale
•
FRB has initiated the process to patent this innovative kiln technology
internationally, while also laying the groundwork for commercialising the
technology in China and beyond.
•
Since its last ASX announcement with respect to the Plant on 12 September 2024, the
Company has already received inquiries from both international and Chinese firms
interested in adopting this energy-efficient solution for manganese-related
processing.
•
In addition, FRB’s technical team has begun designing an electrical kiln tailored for
higher temperature operations such as lithium spodumene processing, expanding
the potential applications of this breakthrough technology.
Firebird Managing Director, Mr Peter Allen, commented: “Our industry-leading sulphate
technical team in China are always looking to improve our proposed production processes, with a
strong focus on reducing our already impressive cost profile to produce high-purity manganese
sulphate.
“The results from testing are very impressive and has demonstrated the exciting potential of the
calcining kiln to move Firebird further down the cost curve and shows the huge competitive
advantages we continue to build by establishing operations in China. We will continue to progress this
technology, with Sunward and Firebird expecting further energy savings on industrial production scale
kiln. Both teams are also very excited by the potential use in a wide range of other industries.
“The high calibre of our development partners in China, including Sunward, reinforces our
commitment and the robust in-country support we have in becoming a near-term, highly competitive
cost producer of manganese sulphate.”

Firebird Metals Limited (ASX: FRB, Firebird or the Company) is pleased to announce the
successful completion of trials on the pilot scale calcining kiln. Results from the trials are highly
encouraging and outline the future potential of the calcining kiln to further reduce the
Company’s already impressive low-cost profile. The pilot scale calcining kiln was installed at Jinshi
High-Tech Industrial Park, located in Jinshi, Hunan Province, China (see ASX announcement dated
12 September 2024.)

The kiln has potential uses in a wide ranging of mineral processing, the Company has filed for
international patents and, since the Company’s last announcement (12 September 2024), has
already received inquiries from both China and internationally. The agreement gives Sunward the
right to market and sell in China with Firebird to receive a 5% of revenue commission, with Firebird
retaining responsibility for international sales and marketing.

Key Observations and Findings from Trial
Design Principle: A core design principle of the calcining kiln is the efficient transfer of energy
from the outer tube to the inner tube. This should be evident through a measurable
temperature differential between the inner and outer tubes at corresponding points along the
kiln.
Temperature Monitoring Setup (refer image 2): Eight temperature gauges are installed on the
outer tube of the kiln. Gauges 1-4 monitor the temperature of the inner tube, while gauges 5-8
measure the temperature of the outer tube.
There are an additional six measurement points located within the heating section, ensuring that
the temperature in the calcining zone remains consistently around 850 degrees Celsius.
As a principle of physics, temperature can decrease exponentially over a short distance.
Currently, there is insufficient insulation material for a very short distance, which presents an
opportunity for significant improvement in kiln performance by addressing this issue.
The heating system of the pilot scale kiln was equipped with 80 kWh coils with actual energy
usage averaged only 8kWh (10% of its capacity). This indicates a substantial margin for
optimisation and efficiency enhancement.
Test Results: The test data clearly demonstrates a significant temperature difference between
the inner and outer tubes, validating the effectiveness of the energy transfer design.
According to the test data, the self-developed manganese ore roasting kiln consumes 80-100
kWh of electricity per tonne of manganese powder roasted, which is 70% more energy-efficient
compared to conventional roasting kilns.
The calcining kiln also uses approximately 5 cubic meters of circulating water, achieving the
desired results. Due to the smaller size of the test kiln, the heat loss per unit of processed
material is higher and both Firebird and Sunward expect that the energy-saving performance of
the industrial-scale kiln will be even greater.
The Company’s experience with other similar industry peers indicates that other kilns typically
consume over 300 kWh per tonne of material processed. Quotes received by Hunan Chemical
Engineering Design Institute3 from reputable suppliers have confirmed these figures. The
seemingly simple innovation and design of the calcining kiln, which was created by the HFBT
team showcases the Company’s commitment to advancing technology and efficiency and the
sector leading capabilities of the team. The potential applications for this technology are
numerous, and may open new avenues for energy savings and operational improvements across
various sectors.
This announce 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
high-purity, 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 234Mt4,5, 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’s other key Project is Hill 616 which provide Firebird with compelling growth
opportunities. Hill 616 contains an Inferred Mineral Resource 2 of 57.5Mt at 12.2% Mn and shares
similar geological traits to Oakover.
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.
