V1V2 tin, lithium, and tantalum 2022 infill drill programme
final update
Andrada Mining Limited (AIM: ATM), an African technology metals
mining company with a portfolio of mining and exploration assets in
Namibia, announces the final results from the tin, lithium, and
tantalum infill drilling programme at the Company's flagship
operation, the Uis Mine ("Uis"). The 2022 drill programme was
undertaken with an aim of upgrading the existing JORC compliant
lithium and tantalum 2019 Mineral Resource (see announcement dated
16 September 2019).
The 51-hole drilling programme, comprising 22 diamond ("DD") and
29 reverse circulation ("RC") drill holes, commenced in 2022 over
the V1/V2 pegmatite. This update announces the results of the
remaining two drill holes as illustrated in Figure 1, to complete
the requisite reporting on all holes for this programme.
Highlights:
-- Pegmatite was intersected in all holes at the depths and
apparent widths predicted by the geological model.
-- Significant pegmatite intersections include:
o 113 m at 0.167% Sn, 68 ppm Ta and 1.15% Li(2) O for the drill
hole V1V2053, from 113 m to 226 m:
-- 59 m at 1.62% Li(2) O from 163 m to 222 m
o 114 m at 0.164% Sn, 85 ppm Ta and 1.15% Li(2) O for the drill
hole V1V2063, from 151 m to 265 m:
-- 48 m at 1.51% Li(2) O from 216 m to 264 m
Anthony Viljoen (CEO) commented:
"We are pleased to announce the final set of drill results for
the remaining two holes of the 2022 drill programme. These drilling
results indicate higher lithium grades and widths of the V1/V2
pegmatite at depth. The overall metal content within these
intersections highlights the potential of the Uis pegmatites and
supports ongoing exploration initiatives.
The selected lithium intersections within the pegmatite provide
valuable guidance on what we can expect as mining progresses and
provides an indication of the full potential of the V1/V2
pegmatite. The commissioning of the lithium pilot plant this year
will inform the optimisation of the lithium process flow diagram,
for the addition of a full-scale lithium production stream within
the main processing plant."
Overview of the results
The pegmatite intersections reported in this update align with
the existing geological model and continue to confirm its spatial
accuracy and interpretation. The drill holes intersected the
pegmatite where the separate V1 and V2 pegmatites have combined
into a single larger unit, with some minor offshoots into the
hanging wall. 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.
Table 1 : Exploration results of diamond drill holes V1V2053 and
V1V2063 indicating the full pegmatite intersection and grades. The
drill holes were oriented vertically, and 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
Notes to editors.
Andrada 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.
