("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 current
exploration programme aims to upgrade the existing Mineral Resource
classification for lithium and tantalum over the areas where tin is
currently classified within the Measured and Indicated categories
for the 2019 Mineral Resource estimate (MRE), stated in accordance
with JORC (2012).
The 50-hole drilling programme, comprising 29 diamond and 21
reverse circulation ("RC") drill holes commenced in 2022 with the
aim of increasing the confidence of the existing lithium and
tantalum Mineral Resource estimates in the V1/V2 pegmatite. The
assay results for 30 holes (60%) have been progressively released
since 2022, this update announces results of an additional five
drill holes as illustrated on Figure 1. The results of the
remaining 15 drill holes will be announced as they become
available.
Highlights:
-- Pegmatite was intersected in all holes at the depths and
apparent widths predicted by the geological model;
-- Significant pegmatite intersections include:
o 28 m at 0.147% Sn, 127 ppm Ta and 0.77% Li(2) O for the drill
hole V1V2033, from 15 m to 43 m;
o 21 m at 0.144% Sn, 107 ppm Ta and 1.03% Li(2) O for the drill
hole V1V2030, from 65 m to 86 m;
o 22 m at 0.150% Sn, 98 ppm Ta and 1.34% Li(2) O for drill hole
V1V2041 from 85 m to 107 m; and
o 19 m at 0.188% Sn, 72 ppm Ta and 0.72% Li(2) O for drill hole
V1V2041 from 111 m to 130 m.
-- Notable intersections of lithium mineralisation within the
pegmatite intersections include:
o 22 m at 1.34% Li(2) O for drill hole V1V2041 from 85 m to 107
m; and
o 21 m at 1.03% Li(2) O for drill hole V1V2030 from 65 m to 86
m.
Anthony Viljoen (CEO) commented:
"We are pleased to announce these exploration drill results
which are once again in line with our high expectations for the
V1/V2 pegmatite ore body. The drill holes reported in this
announcement are distributed over the strike of the pegmatite and
are proof of the consistency of lithium, tin, and tantalum
mineralisation. We are particularly encouraged by the lithium
grades intersected in drill holes V1V2041 and V1V2056, up to 1.34%
lithium oxide, which further demonstrate the unrealised potential
of the V1/V2 orebody. We look forward to updating the Mineral
Resource Estimate in support of our by-product development projects
for tantalum and lithium."
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.
The dip angle of the pegmatites varies from 24 degrees to 48
degrees and the reported drill holes are orientated vertically such
that the reported intersections represent apparent thickness.

V1V2027, V1V2033, V1V2030, and V1V2041 indicating the full
pegmatite intersection and pegmatite grades. Intersections are
indicative of apparent thickness and not true thickness. Note that
apparent thickness is greater than true thickness.

Each drill hole was geologically and geotechnically 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.
