       ALPHAMIN CONTINUES TO INTERCEPT HIGH GRADE TIN MINERALISATION AT
                                MPAMA SOUTH

June 08, 2021 – Alphamin Resources Corp. (AFM:TSXV, APH:JSE AltX, “Alphamin” or the
“Company”), a producer of 4% of the world’s mined tin from its high-grade operation in the
Democratic Republic of Congo, is pleased to provide additional assay results on its Mpama
South Exploration Drilling programme.

Chief Executive Officer, Maritz Smith comments:

“The Mpama South Prospect continues to deliver exceptional tin intercepts. Based on the first
two batches of drill results, the continued presence and orientation of high-grade samples point
to the potential for yet another high-grade deposit, some 750m south of our current operation.
With the recent commencement of the deeper drilling phase at Mpama South, we believe we
are heading into even more exciting times”.

Mpama South Exploration Drilling Update

Mpama South is a high-grade tin discovery, located 750m south of Alphamin’s operating Bisie
mine. A small diamond drilling programme of sixteen (16) drillholes completed in 2016 recorded
notable cassiterite intercepts in similar alteration styles to the Mpama North mine. Alphamin
re-commenced its Mpama South diamond drilling exploration activities in December 2020 and
completed the first two phases of drilling by the end of May for a total of 10,000 metres and
forty-six (46) drillholes. Phase 3 for 6,800 metres and twenty-four (24) holes has already
commenced for expected completion in August 2021. All three phases for ~16,800 metres are
intended to form the basis of a Mineral Resource estimation exercise, the results of which are
expected to be announced by the end of 2021. Infill drilling and further step-out drilling will
continue from August for the remainder of 2021.

Selected significant intercepts1 from the new batch of assays received in the Main Zone from
the Mpama South drilling program are listed below as apparent widths. Sample preparation is
detailed in Appendix 1 and all intercepts >0.5% Sn are detailed in Appendix 2:-
   •   BGH033: 6.4 metres @ 7.32% Sn from 259.0 metres
   •   BGH035: 13.0 metres @ 2.96% Sn (incl. 5.3 metres @ 6.4% Sn) from 152.0 metres
   •   BGH039: 21.0 metres @ 2.20% Sn (incl. 8.0 metres @ 4.26% Sn) from 145.0 metres
   •   BGH045: 6.9 metres @ 3.24% Sn from 176.7 metres
While significant new intercepts in the newly discovered footwall zone are as follows:-
   •   BGH037: 3.0 metres @ 3.81% Sn from 154.0 metres
   •   BGH038: 2.9 metres @ 5.22% Sn from 151.7 metres
   •   BGH045: 1.1 metres @ 31.55% Sn from 120.7 metres

The above intercepts together with the previously announced batch of significant intercepts
repeated below1, point to a potential high-grade deposit at Mpama South:
Main Zone:
   •   BGH030: 10.6 metres @ 4.85% Sn from 141.9 metres
   •   BGH032: 20.0 metres @ 2.07% Sn from 185.0 metres
   •   BGH025: 14.6 metres @ 2.70% Sn from 220.10 metres
Footwall Zone:
   •   BGH034 3.2 metres @ 11.99% Sn from 174.8 metres
   •   BGH022: 5.5 metres @ 3.99% Sn from 75.0 metres
   •   BGH030: 1.4 metres @ 7.24% Sn from 110.0 metres

1   All intercepts are reported as apparent widths and are not true widths

Although only shallowly drilled to date, tell-tale signs already lead management to believe that
the potential for a high grade shoot exists at Mpama South (Figure 1), possibly similar to that
at the adjacent producing Mpama North mine.

Appendix 1: SAMPLE PREPARATION, ANALYSES AND QUALITY CONTROL AND
QUALITY ASSURANCE (QAQC)

After receipt of diamond drillcore 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 75?m 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 pulverizer
using a carbon steel ring set to 85 % passing 75?m. 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 60pmm Sn on average) and negligible
sampling errors. Further verification work is in progress by additional check assays by SGS
South Africa (Pty) Ltd.

The Company’s Qualified Person (QP) for the drill programme, has verified the data disclosed,
including drill core, sampling and analytical data in the field and lab.
