Appointment of joint corporate brokers
-- Appointment of Joh. Berenberg, Gossler & Co. KG
("Berenberg") and WH Ireland Limited ("WHI") as joint corporate
brokers to access a wider investor base and top-tier research
capability.
Anthony Viljoen, Chief Executive Officer, commented:
"We made significant strides in Q3 towards becoming a
multi-technology producer. Drilling confirmed notable lithium
intersections at Lithium Ridge, and post-period metallurgical
production of spodumene concentrate marked major milestones towards
entering downstream lithium markets. We also launched an
exploration programme at Brandberg West, with the potential to
expand our portfolio to include tungsten and copper.
"Operational performance improved against the same quarter in
FY2023 due to the lower comparative base. We aim to further enhance
cost efficiencies by increasing tin production through the CI2
project. The tin royalty will provide the necessary funding to
produce up to 2,000 tonnes of contained tin per annum, positioning
Andrada as a major global supplier.
"To further strengthen our investor outreach, we have appointed
Berenberg and WHI as joint corporate brokers. Together with our
current corporate brokers, Hannam & Partners, these
appointments give us extensive reach into the UK and European
capital markets."

(1) Production period includes a five - week shutdown of the
processing plant from 7 September 2022 - 13 October 2022 which was
required to complete the construction and commissioning of the
expanded crushing and tin concentrating circuits.
(2) C1 refers to operating cash cost per unit of production
excluding selling expenses and sustaining capital expenditure
associated with
Uis Mine.
(3) C2 operating cash cost is the C1 amount including selling
expenses (logistics, smelting and royalties).
All-in sustaining cost (AISC) incorporates all costs related to
sustaining production, capital expenditure associated with
developing
and maintaining the Uis operation as well as pre-stripping waste
mining costs.
*Tin recovery includes stockpiles
Tin concentrate production increased by 139% to 346 tonnes (Q3
FY2023: 145 tonnes) resulting in a 132% increase in contained tin
to 202 tonnes YoY. The plant processing rate increased by 29% YoY
reflecting the improvement in productivity resulting from the
modular plant expansion in Q3 FY2023. It is important to highlight
that the significant variances YoY are due to the low production
volumes in Q3 FY2023 arising from the planned plant outages to
implement the expansion project.
Lithium and tantalum development
Lithium Pilot Plant
Approximately 10 tonnes of saleable concentrate were produced in
October 2023. The production rate is expected to increase to 250
tonnes per month by the end of March 2024. By the end of February
2024, the Company aims to produce concentrate for initial
commercial sales into the spot market, a goal which the Directors
believe is a realistic prospect. Initial internal estimates suggest
that the petalite concentrate from the Pilot Plant could be priced
between USD1 600 and USD2 200 per tonne in the current spot market
(pricing provided for guidance purposes only). Importantly, Andrada
has commenced production of petalite concentrate for metallurgical
testwork to determine appropriate specifications for the lithium
battery refinery market.
Tantalum Circuit
Optimisation of the circuit is ongoing to improve productivity.
The Company is on track to supply tantalum to AfriMet on a
quarterly basis, commencing March 2024.
EXPLORATION
Lithium Ridge drilling results
Lithium Ridge infill channel sampling programme confirmed the
presence of continuous mineralisation at surface over a 6 km strike
length of multiple mineralised pegmatites. The initial RC drilling
programme confirmed the continuation of mineralisation at depth
within several pegmatites. The primary lithium minerals identified
through drilling were spodumene and petalite with notable lithium
contents at grades exceeding 2% Li O. (See announcement dated 29
August 2023, 6 September 2023 & 18 September 2023).
Lithium CY 2024 exploration strategy
The exploration programme plan for CY2024 was completed during
the quarter, with the aim of enhancing the understanding of
mineralisation on all the Company's mining licences. (See
announcement dated 27 November 2023).
These plans include:
-- Uis (ML134): Resource validation drilling over the Northern
and Central pegmatite clusters to enhance the current Mineral
Resource Estimate ("MRE") classification of tin, as well as to
establish the mineral potential for lithium and other technology
metals.
-- Lithium Ridge (ML133): High-density drilling campaign at the
historical TinTan mine for the development of a maiden MRE, and to
enhance understanding of the lithium mineralisation within the
identified high priority pegmatites.
-- Spodumene Hill (ML129): Drilling programme to delineate the
higher grade spodumene zones within the B1 and C1 pegmatites, as
well as on the mapped satellite bodies surrounding the main
mineralised units.
Brandberg West (EPL 5445)
Brandberg West has multiple documented mineral occurrences
including known concentrations of tin and tungsten. The potential
production of tungsten will expand the number of technology metals
within the Company's portfolio. Copper mineralisation has also been
documented within the mineralised area and will be investigated as
a potential by-product. A dual phased development plan to
investigate multiple occurrences of mineralisation through sampling
and geological mapping will be undertaken to determine potential
enrichment trends. (See announcement dated 12 November 2023).
Metallurgy
Lithium production focus
The primary lithium minerals at Andrada's three mining licences
are petalite and spodumene, although their distribution varies
across the licence areas. The explored pegmatites on Uis are
petalite-dominant but are spodumene-dominant on Lithium Ridge and
Spodumene Hill. Andrada's lithium development strategy will
incorporate the production of both petalite and spodumene
concentrates, enabling multiple off-take options for both the
industrial (glass-ceramics) and chemical (battery) concentrate
markets. The Company is implementing metallurgical testwork to
assess the possibility of producing battery grade lithium hydroxide
as well as to optimise production from Uis, Spodumene Hill and
Lithium Ridge.
Sustainability
Andrada's progress against its five-year sustainability
strategy, remains on track. During the quarter under review, the
Company increased its social engagement in line with a pledge to
fortify local communities. The Company continued implementing
safety campaigns to further instil and improve safety
performance.
There were no fatalities, but two lost time injury incidents
occurred during the quarter resulting in an increased LTIR of 2.45
at the end of the quarter under review, compared to 0.86 at the end
of Q2 FY2024. However, the performance was an improvement on the
5.47 rate at the end of Q3 FY2023. These incidents were thoroughly
investigated to ensure sufficient mitigation measures. Quarterly
independent audits continue to be conducted to address any
identified safety gaps.
The Company completed its Biodiversity Assessment and Climate
Change Scenario Analysis to provide vital insights for biodiversity
preservation and climate-related resilience planning. Concurrently,
the Andrada sustainability team has been reviewing the Global
Industry Standard on tailings management to minimise environmental
impact and mitigate risks. These combined efforts place the Company
in a good position to address any future challenges with foresight
and responsibility.
FINANCial
All costs in the quarter decreased YoY due to the economies of
scale from higher volumes and improved efficiencies. Although the
C1 and C2 costs decreased quarter-on-quarter remaining within the
management guidance, the AISC was approximately 2% higher at USD30
452. The latter is expected to decrease to within management
guidance as production volumes increase.
Andrada received the USD 25million Orion funding including a
USD12.5 million tin royalty. Furthermore, the NAD 100 million
funding from DBN was finalised during the quarter, with receipt of
50% of the funds for the CI2 project at Uis Tin Mine. The Company
is targeting contained tin production of up to 2 000 tonnes to
achieve the tin royalty tonnage.
The combined cash and cash equivalent balance on 30 November
2023 was GBP21 million (USD26 million).
CORPORATE
The strategic process to identify an appropriate partner to
participate in the lithium development is progressing well. Further
updates on the strategic process will be communicated in due course
as appropriate.
POST-PERIOD
High-grade spodumene concentrate produced through flotation
Laboratory - scale flotation test work was undertaken on two
samples selected from exploration drill chips produced during
reverse circulation drilling. The aim of these tests was to
investigate lithium mineral composition and recovery potential in
an area of the Lithium Ridge licence where significant spodumene
occurrence had been observed during exploration. The samples
yielded a weighted average feed grade of 1.69% Li O and 15.2%
spodumene, a weighted average concentrate grade of 6.8% Li O or 75%
spodumene and a weighted average recovery 76% Li O or 80%
spodumene.
Appointment of Joh. Berenberg, Gossler & Co. KG and WH
Ireland Limited as corporate brokers
The Company has appointed Berenberg and WHI as joint corporate
brokers as of 19 December 2023. Berenberg's research expertise and
global investor reach will enhance awareness of Andrada's value
proposition, while WHI provides access to a new segment of
investors. Berenberg and WHI will work alongside Hannam and
Partners Advisory Limited, the Company's existing corporate broker,
positioning us for continued growth and success
