Uis Proximal Pegmatites Exploration Drilling Results
Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF), a tin producer with a
critical raw materials portfolio of mining and exploration assets in Namibia,
is pleased to announce the initial batch of drill results for 13 proximal
(polymetallic) pegmatites located in the previously mined areas of the Uis
mining licence (ML134) ("Uis"). These pegmatites are within a 3km radius
from the existing processing plant at the Uis Tin Mine and constitute part of
a swarm comprising approximately 180 mineralised pegmatites identified to date
within the license area. The objectives of the drill programme ("Programme")
are to validate the historical data and to investigate the by-product
potential of the pegmatites within the previously mined areas. The on-going
Programme covering the 13 pegmatites, comprises 44 diamond ("DD") and 177
reverse circulation ("RC") drill holes. The results in this announcement are
for 136 holes (61%) because the Company is awaiting analysis of the remaining
85 drill holes.
Highlights
§ Confirmed mineralisation in all 13 pegmatites along a 5km strike
§ Significant intersections with notable high grades in tin ("Sn"), tantalum
("Ta") and lithium ("Li₂O") include:
− 50m at 0.16% Sn, 0.44% Li₂O and 130 ppm Ta, from 9.00m to 59.00m,
for the drill hole P5_003
· Including 5m at 0.50% Sn and 153 ppm Ta from 18.00m to 23.00m
− 59.76m at 0.14% Sn, 1.23% Li₂O and 38 ppm Ta, from 101.92m to
161.68m, for the drill hole K5_018
· Including 31m at 0.17% Sn and 1.70% Li₂O, from 128.00m to 159.00m
− 85m at 0.18% Sn, 0.33% Li₂O and 53 ppm Ta, from 99.00m to 184.00m,
for the drill hole K5_019
− 6m at 0.51% Sn, 0.07% Li₂O and 119 ppm Ta, from 48.00m to 54.00m,
for the drill hole K3_021
· Including 2m at 1.13% Sn and 281 ppm Ta from 52.00m to 54.00m
− 46m at 0.17% Sn, 0.77% Li₂O and 59 ppm Ta, from 90.00m to 136.00m,
for the drill hole V13_012
· Including 2m at 1.76% Li₂O from 133.00m to 135.00m
− 25.89m at 0.33% Sn, 0.54% Li₂O and 90 ppm Ta, from 114.93m to
140.82m, for the drill hole V13_018
· Including 4m at 0.59% Sn from 131.00m to 135.00m
§ All drilled pegmatites remain open ended at depth
Anthony Viljoen (CEO) commented:
"These strong drill results reaffirm the scale and quality of mineralisation
across Uis's extensive swarm of pegmatites. High-grade intersections such as
1.13% tin, 1.76% lithium oxide, and 281ppm tantalum, validate our strategy to
grow the resource towards 200 million tonnes and support future reserve
definition. Importantly, these results highlight the opportunity to restore
Uis Tin Mine to its historical status as a major global tin producer-now with
the added advantage of lithium and tantalum as high-value co-products. The
polymetallic nature of the deposit significantly enhances Uis's economics and
aligns with growing demand for critical metals across global markets.
Our focus is clear - unlock the full value of Uis through disciplined growth,
targeted investment, and a clear path to production scale-up. With a 5km
strike length and broad mineralised zones, we believe Uis has the potential to
become a cornerstone asset in Andrada's long-term growth strategy."
Overview of the results
The reported pegmatite intersections align with the geological model developed
from historical ISCOR drill information. The previously announced, JORC 2012
compliant inferred resource over most of these pegmatites, was focussed on
tin. (See announcement dated 23 January 2023). The inferred resource estimate
of 57 million tonnes or 74 857 tonnes of contained metal was declared in
2023, based on historical drill data for 809 holes over the pegmatites.
The main objectives of the current Programme are to further validate the
historical information for tin mineralisation and to improve the MRE
classifications. The Programme also provides an initial indication of the
potential for the other metals primarily, Li and Ta within the proximal
pegmatites. The Programme has investigated the areas where continuity
information is required, and accordingly a few deeper holes were drilled to
confirm the pegmatite extensions at depth. These deeper holes, extending below
the historical data points, confirm that the pegmatites continue down dip and
tend to thicken in a similar manner to the V1V2 pegmatite. The deepest
intersection reported over these proximal pegmatites is 238m compared with
450m recorded for the V1V2 pegmatite. The upside potential of further down dip
extensions will be investigated in future programmes.
Of the 221 holes which have been completed, six holes, namely V5_014, V8_001,
V8_008, V12_031, V13_001 and V13_003, did not intersect any pegmatite
lithologies due to deflection away from the planned intersection point, as
illustrated in Figure 6 where hole V13_019 deviates away from the target. The
dip angle of the pegmatites varies from approximately 22 degrees to 60 degrees
and appears to increase with depth. Planned inclined drill holes were aimed to
intersect the pegmatites perpendicular to strike. In instances where the
average dip angle is greater than 85 degrees, the hole is recorded as
vertical. All reported intersections should be considered to represent
apparent thickness.
Table 1: Results of the holes which intersected pegmatites. The entire
pegmatite intersection and grades are reported. Intersections described as
'including' refer to a portion of the whole pegmatite intersection with
significant metal values. The reported intersections are indicative of
apparent thickness, which is greater than true thickness.

Each DD hole was geologically and geotechnically logged before being sampled
as half core. Each RC hole was geologically logged with half of the material
produced per meter being sampled and shipped for analysis. The sample analysis
was undertaken by UIS Analytical Services, a certified independent laboratory
in South Africa, using a peroxide fusion. ICP-OES analysis was utilised for
the reporting of major and minor elements and ICP-MS
for the trace elements.

the analysis of drill hole K3_001 is pending. The historical holes drilled by
ISCOR commence above the surface, reflecting the mining that has taken place
since the holes were completed
Figure 6: Section line B-B' displaying a projection of the holes drilled in
the Southern (V) cluster reported in this announcement. Hole V13_019 deflected
away from the primary target but intercepted two mineralised pegmatites in the
hanging wall which were previously unknown

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 the shape of
the mineralised unit. 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 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.
Xenolith A foreign rock fragment (e.g., schist) within an intrusive body (e.g.,
pegmatite) that is unrelated to the igneous body.
