("Andrada" or the "Company")
Lithium And Tantalum Infill Drill Programme Update
Andrada Mining Limited, formerly Afritin Mining Limited (AIM:
ATM), an African technology metals mining company with a portfolio
of mining and exploration assets in Namibia, announces further
results from the lithium and tantalum infill drilling programme at
the Company's flagship operation, the Uis Mine ("Uis"). The
programme aims to upgrade the existing lithium and tantalum 2019
Mineral Resource, stated in accordance with JORC (2012).
This update announces the results of 14 drill holes as
illustrated on Figure 1. These results increase the total number of
holes reported on to 49 of the 50-hole drilling programme,
comprising 29 diamond and 21 reverse circulation ("RC") drill
holes. The aim of the programme is to increase the confidence of
the existing lithium and tantalum Mineral Resource estimates in the
V1/V2 pegmatite.
Highlights:
-- Pegmatite was intersected in all holes at the depths and
apparent widths, as predicted by the geological model;
-- Significant pegmatite intersections include:
o 94 m at 0.152% Sn, 66 ppm Ta and 1.18% Li(2) O for the drill
hole V1V2051, from 139 m to 233 m;
o 43 m at 0.147% Sn, 92 ppm Ta and 1.08% Li(2) O, from 57 m to
100 m; and 27 m at 0.25% Sn, 60 ppm Ta and 1.09% Li(2) O from 117 m
to 144 m, for the drill hole V1V2048;
o 63 m at 0.151% Sn, 79 ppm Ta and 1.43% Li(2) O for drill hole
V1V2043 from 59 m to 122 m;
o 30 m at 0.141% Sn, 117 ppm Ta and 1.34% Li(2) O for drill hole
V1V2035 from 82 m to 117 m.
o 35 m at 0.140% Sn, 108ppm Ta and 1.23% Li(2) O for drill hole
V1V2038 from 71m to 106 m.
-- Notable intersections of lithium mineralisation within the
pegmatite intersections include:
o 63 m at 1.43% Li(2) O for drill hole V1V2043 from 59 m to 122
m;
o 30 m at 1.34% Li(2) O for drill hole V1V2035 from 82m to 112
m;
o 35 m at 1.23% Li(2) O for drill hole V1V2038 from 71m to 106
m.
Anthony Viljoen (CEO) commented:
"As we continue to report on the drilling programme results, I
am pleased that they further highlight the mineralisation potential
of the V1/V2 pegmatite ore body. The additional 14 holes being
reported on in this announcement are located in the centre of the
pegmatite and show that the potential lithium, tin, and tantalum
mineralisation continuing at depth. The higher lithium grades of up
to 1.43% lithium oxide are particularly exciting because they
further demonstrate the unrealised potential of the V1/V2 orebody
and support the early development of a lithium processing plant. We
look forward to providing additional information on the lithium
resource through an updated Mineral Resource Estimate in the near
future."
Overview of the results
The pegmatite intersections reported in this update align with
the current geological model, confirming its spatial accuracy. The
drill holes intersected the pegmatite at shallow depths where the
V1 and V2 bodies have bifurcated into individual units, as well as
at greater depths where the units coalesce into a single pegmatite,
drill holes V1V2058 and V1V2080 were stopped within the pegmatite
and do not represent the full intersection. The dip angle of the
pegmatites varies from 24 degrees to 48 degrees and the majority of
reported drill holes are orientated vertically such that the
reported intersections represent apparent thickness. Holes
V1V12050, V1V12051 and V1V12034 are inclined and intersected the
pegmatite at approximately right angles.

V1V2050, V1V2051, V1V2052, V1V2054, V1V2037, V1V2048, V1V2058,
V1V2080, V1V2043, V1V2035, V1V2040, V1V2038, and V1V2034 indicating
the pegmatite intersection and pegmatite grades. Intersections are
indicative of apparent thickness and not true thickness. Drill hole
V1V2058 and V1V2080 ended within the pegmatite. Note that apparent
thickness is greater than true thickness.

Each drill hole was geologically logged before being sampled.
The sample analysis was undertaken by UIS Analytical Services, a
certified independent laboratory, using a peroxide fusion. ICP-OES
analysis was utilised for major and minor elements and ICP-MS
utilised for the trace elements.

Glossary of technical terminology
Apparent thickness The relationship between apparent width and true thickness is based on the formula by Addie
(1968 Economic Geology, vol 63, pp 188-189).
Dip angle The angle of inclination measured downward from horizontal.
-------------------------------------------------------------------------------------------------
Geological model The interpretation of mineralisation and geology that controls mineralisation. This is usually
generated in a three-dimensional computer environment.
-------------------------------------------------------------------------------------------------
Mineral resources Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred,
Indicated and Measured categories. An Inferred Mineral Resource has a lower level of confidence
than that applied to an Indicated Mineral Resource. An Indicated Mineral Resource has a higher
level of confidence than an Inferred Mineral Resource but has a lower level of confidence
than a Measured Mineral Resource.
-------------------------------------------------------------------------------------------------
Pegmatite An igneous rock typically of granitic composition, which is distinguished from other igneous
rocks by the extremely coarse and systematically variable size of its crystals, or by an
abundance
of crystals with skeletal, graphic, or other strongly directional growth habits, or by a
prominent
spatial zonation of mineral assemblages, including monomineralic zones.
-------------------------------------------------------------------------------------------------
Xenolith A foreign rock fragment (e.g., schist) within an intrusive body (e.g. pegmatite) that is
unrelated
to the igneous body.

About Andrada Mining Limited
Andrada Mining Limited, formerly Afritin Mining Limited, is a
London-listed technology metals mining company with a vision to
create a portfolio of globally significant, conflict-free,
production and exploration assets. The Company's flagship asset is
the Uis Mine in Namibia, formerly the world's largest hard-rock
open cast tin mine.
Lithium laboratory test work completed during the 2022 calendar
year indicated a high-grade, ultra-low iron lithium petalite
concentrate. The test work to convert lithium petalite concentrate
to battery-grade lithium hydroxide was initiated with Nagrom, a
leading Australian processing company, and commercial engagements
with lithium petalite concentrate off - takers are on-going.
An exploration drilling programme is currently underway with the
aim of expanding the tin resource over the fourteen additional,
historically mined pegmatites, all of which occur within a 5 km
radius of the current processing plant. The Company has set a
mineral resource target of 200 Mt to be delineated within the next
5 years. The substantial mineral resource potential allows the
Company to consider economies of scale.
Andrada is managed by a board of directors with extensive
industry knowledge and management team with deep commercial and
technical skills. Furthermore, the Company is committed to the
sustainable development of its operations and the growth of its
business. This is demonstrated by how the leadership team places
significant emphasis on creating value for the wider community,
investors, and other key stakeholders. Andrada has established an
environmental, social and governance system which has been
implemented at all levels of the Company and aligns with
international standards.
