Finalising completion of the Maiden Mineral Resource estimation on Mpama South
Mpama South Update and Forthcoming Completion of a Maiden Mineral Resource
Mpama South is the high-grade tin deposit adjoining the southern end of Alphamin’s operating
Mpama North mine. By year end 2021, 24,235 metres of drilling has been completed in 89
drillholes. Including the original sixteen 2014/15 drillholes, 23,109m and 79 drillholes will form the
basis of the Maiden Mineral Resource estimation exercise which is nearing completion, results
expected to be announced in February 2022. Subsequent Mineral Resource updates are
1 Data obtained from International Tin Association Tin Industry Review 2020
2 All intercepts are reported as apparent widths and are not true widths
expected to be announced throughout 2022 as Alphamin plans to aggressively drill the deposit
which is open in multiple directions.
Selected significant intercepts from the most recently received batch of drillhole assays, including
the best intercept to date at Mpama South in BGH079 in terms of contained metal (Sn% x metres),
are listed below as apparent widths:
BGH079: 15.6 metres @ 5.00% Sn from 290.2 metres, including 10.0 metres @ 6.1%
from 291.1 metres, and
BGH079: 9.0 metres @ 5.63% Sn from 316.9 metres
BGH077: 4.8 metres @ 4.68% Sn from 335.3 metres and 11.4 metres @ 2.23% Sn from
318.8 metres
BGH084: 26.0 metres @ 2.71% Sn from 280.3 metres
BGH086: 6.1 metres @ 2.75% Sn from 275.35 metres
The success of the Mpama South drilling is such that the zone of high-grade mineralisation has
grown substantially throughout 2021. Visual cassiterite intercepts at Mpama South are now within
85 metres of Mpama North mine and are in the export and assay pipeline already. Figure 1
demonstrates the location of received assays, awaited assays on visual cassiterite intercepts and
proximity of these to the Mpama North Mine based on drilling to date. The complete list of assayed
intercepts to date is shown in Appendix 2.

Mpama North Update
Drilling commenced on Mpama North in July 2021 on the Mpama North Deeps target. The first
drillholes showed increased structural complexity associated with a northeast-southwest cross-
cutting fault which had constrained the Deeps target to smaller extents than originally planned.
After revising the model and drilling approach, several high-grade intercepts of visual cassiterite
were intersected east of the fault subsequently as well as west of the fault in the shallower Oso
target. Drilling continues in 2022 to close out what is left of the Deeps target, the shallow Oso
target as well as the down Dip eastern side of Mpama North which still remains open (Figure 2).
A particularly significant new intercept from the first batch of drillhole assays on Mpama North is
listed below as an apparent width. The intercept is the second best drillhole at Mpama North
drilled to date in terms of contained metal (Sn% x metres):-
MND011: 19.6 metres @ 17.16% Sn from 419.3 metres, including 14.5 metres @ 23.0%
The complete list of assayed intercepts to date is shown in Appendix 2.
Bisie Ridge Exploration Drilling
The Bisie Ridge is a 13km long ridge hosting both the Mpama North and Mpama South deposits.
Only a fraction (~20%) of this ridge has been intensively drill tested to date. The full length of the
ridge has been the subject of a follow up geochemical investigation in 2021 confirming tin and
other base metal anomalies over the majority of its length. Six high priority drill areas have been

identified in 2021 in conjunction with the Company’s expert structural advisors TECT. With the
goal of making new discoveries, the Company is pleased to announce that the first of these six
targets commenced drill testing in January 2022.

Appendix 1: SAMPLE PREPARATION, ANALYSES AND QUALITY CONTROL AND QUALITY
ASSURANCE (QAQC)
After receipt of diamond drill core from the drillers at the drill rig in marked core trays, core was
transported to the Company’s core shed by the site geologist for logging and sampling. After
sample mark up, lithological and geotechnical logging and photography, the core was split
longitudinally in half using a water-cooled rotating diamond blade core saw. The cut core was
replaced into the core tray with the half to be sampled facing upward. Based on previous
experience at Bisie with high density variability and at the qualified person’s instruction (Mr J.
Witley of MSA Group), specific gravity (SG) was performed exclusively on the half core that was
to be sampled. The Archimedes method of weight in air vs weight in water was used on the whole
length of the half core that was to be sampled and then replaced in the core trays.
Air dried samples were placed in pre-numbered sample bags together with pre-printed numbered
sample tickets, which were cross-checked afterwards to prevent sample swaps. Sample bags
were sealed using a plastic cable tie and then placed into poly-weave sacks which were in turn
sealed with plastic cable ties. Each poly-weave sack was marked with a number and the sample
numbers contained within, ready for delivery to the on-site Alphamin-Bisie laboratory for sample
preparation.
At the laboratory, samples were first checked off against the submission list supplied and then
weighed and oven dried for 2 hours at 105 degrees Celsius. The dried samples were crushed by
jaw crusher to 75% passing 2mm, from which a 250g riffle split was taken. This 250g split was
pulverised in ring mills to 90% passing 75μm from which a sample for analysis was taken.
Samples were homogenised using a corner-to-corner methodology and two samples were taken
from each pulp, one of 10g for on-site laboratory assaying and another 150g sample for export
and independent accredited 3rd party laboratory assaying.
For the initial on-site laboratory assay, 10 grams of pulverised sample is mixed with 2 grams of
binder before press pellet preparation at 20t/psi for 1 minute. Press pellets are analysed in a
desktop Spectro Xepos XRF analyser, twelve at a time, for Sn, Fe, Zn, Cu, Ag, Pb and As along
with a standard, duplicate and blank. The analytical method conducted on the pressed pellet has
an expected 10% precision and an upper detection limit of 70,000ppm and lower detection limit
of 500ppm. Over-limit samples are titrated by wet chemistry with an upper limit validation of 70%
Sn. The on-site laboratory assays are merely an exploration tool and were not used for reporting
the exploration results, which are based solely on the ALS assays.
The 150g sample is packaged in sealed paper sample envelopes and packed in a box for export
in batches of approximately 500 samples and prepared for export authorisation with national
authorities. Once authorisation is received, samples are air-couriered to ALS Group in
Johannesburg South Africa, a subsidiary of ALS Limited, which is an independent commercial
analytical facility. ALS operations are ISO 9001:2015 certificated and the Johannesburg office is
ISO 17025 accredited for Chemical Analysis by SANAS (South African National Accreditation
System, facility number T087), although the accreditation does not extend to the methods used
for tin.
Received samples at ALS Johannesburg are checked off against the list of samples supplied and
logged in the system. Quality Control is performed in the way of sieve tests every 50 samples and
should a sample fail, the preceding 50 samples are ground in a ring mill pulveriser using a carbon
steel ring set to 85 % passing 75μm. Samples are analysed for tin using method code ME-XRF05
conducted on a pressed pellet with 10% precision and an upper limit of 5,000ppm. The over-limit
tin samples are analysed as fused disks according to method ME-XRF15c, which makes use of
pre-oxidation and decomposition by fusion with 12:22 lithium borate flux containing 20% Sodium
Nitrate as an oxidizing agent, with an upper detection limit of 79% Sn.
Method code ME-ICP61 (HF, HNO3, HClO4 and HCl leach with ICP-AES finish) is used for 33
elements including base metals. ME-OG62, a four-acid digestion, is used on ore grade samples
for lead, zinc, copper and silver. Both methods are accredited by SANAS.
The program is designed to include a comprehensive analytical quality assurance and control
routine comprising the systematic use of Company inserted standards, blanks and field duplicate
samples, internal laboratory standards and analysis at an accredited laboratory. The pulps were
accompanied by blind QAQC samples inserted into the sample stream by the Alphamin-Bisie
geologists. These comprised blank samples, certified reference materials and pulp duplicates
each at an insertion rate of approximately 5%.
The QAQC results demonstrate that the assay results are both accurate and precise with an
insignificant amount of contamination (in the order of 10pmm Sn on average) and negligible
sampling errors. Further verification work is in progress by additional check assays by SGS South
Africa (Pty) Ltd.
