Alphamin Announces Successful Infill Drilling at Mpama South with Increase IN Both Resource Confidence and Mineral Resources
ALPHAMIN ANNOUNCES SUCCESSFUL INFILL DRILLING AT MPAMA SOUTH WITH
INCREASE IN BOTH RESOURCE CONFIDENCE AND MINERAL RESOURCES
10 February 2023 – Alphamin Resources Corp. (AFM:TSXV, APH:JSE AltX, “Alphamin” or the
“Company”), a producer of 4% of the world’s mined tin1 from its high-grade operation in the
Democratic Republic of Congo, is pleased to announce completion of the infill drilling campaign
at Mpama South and an updated Mineral Resource Estimate (MRE) for Mpama South.
HIGHLIGHTS
Substantially improved the confidence of Mineral Resources at Mpama South whilst
extending the known mineralisation boundary.
Increased Indicated Resources by 286% to 3.26Mt based on assays from 63 additional
infill and extensional drillholes.
Mpama South Mineral Resources now stand at:
3.26Mt @ 2.46% Sn for 80.2kt contained tin in the Indicated category; and
2.84Mt @ 2.42% Sn for 68.7kt contained tin in the Inferred category.
Significant additional resource growth potential at Mpama South as the deposit still
remains open down-dip.
Mpama South Mine construction works progressing according to plan – project
completion expected to increase Alphamin’s annual contained tin production from the
current 12,000tpa to ~20,000tpa, approximating 6.6% of the world’s mined tin1.
Mpama South Updated Mineral Resource Estimate
In just 24 months, Alphamin has:
delivered a top-10 globally significant CRIRSCO compliant tin deposit by contained tin 1 at
Mpama South;
grown the resources to ~2.2 times versus the Maiden Mineral Resources and PEA 2
numbers;
increased resource confidence across the deposit; and
commenced mine construction through own cashflows.
This brings forward an additional planned ~7,200tpa contained tin production, which will make
Alphamin one of the largest tin producers globally and delivers on the Company strategy of
organic growth and creating shareholder value.
The updated Mineral Resource for Mpama South follows eight months after the previous update
announced on 31 May 2022. The update is based on receipt of assays for another 63 infill and
extensional drillholes completed subsequent to the previous estimate which was based on 124

drillholes. The updated Mineral Resource is presented in Figure 1 along with the direction in which
mineralisation is still open down dip and significant high grade periphery drilling intercepts.
The updated MRE now includes results from 187 drillholes at Mpama South as well as 6 drillholes
drilled in 2015 in the area between Mpama South and the Mpama North ore body. The MRE was
estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice
Guidelines (2019) and is reported in accordance with the 2014 CIM Definition Standards.

The Mineral Resource is classified into the Indicated and Inferred categories and is reported at a
base case tin cut-off grade of 1.0%, which satisfies reasonable prospects for economic extraction.
Mpama South Indicated Resources increased by ~286% to 3.26Mt by converting Inferred
Resources, while Inferred Resources grew nominally by ~275kt (excluding those tonnes
converted to Indicated). The Mineral Resource Estimate, which is effective as of 07 February
2023, is presented in Table 1 below:

Classification Tonnes (millions) Sn % Sn Tonnes

Indicated3 3.26 2.46 80.2
Inferred4 2.84 2.42 68.7
Mineral Resources that are not Mineral Reserves do not have a demonstrated economic viability
and require advanced studies and economic analysis to prove their viability for extraction.
Extensional drilling down-dip and in the shallower northern and southern portions of Mpama South
can be conducted at the Company’s election to carry on extending known mineralisation at
Mpama South, which is still open in multiple directions. High grade drillholes around the
peripheries where mineralisation remains open are highlighted in Figure 1, showing the remaining
prospectivity for Resource expansion. However, for 2023, the focus will primarily be aimed at the
Mpama South Mine construction and commissioning efforts, while exploration drilling will be
curtailed, instead, focusing on further field work campaigns to support future programs.
The MRE has been completed by Mr. J.C. Witley (BSc Hons, MSc (Eng.)) who is a geologist with
34 years’ experience in base and precious metals exploration and mining as well as Mineral
Resource evaluation and reporting. He is a Principal Resource Consultant for The MSA Group
(an independent consulting company), is registered with the South African Council for Natural
Scientific Professions (SACNASP) and is a Fellow of the Geological Society of South Africa
(GSSA). Mr. Witley has the appropriate relevant qualifications and experience to be considered
a “Qualified Person” for the style and type of mineralisation and activity being undertaken as
defined in National Instrument 43-101 Standards of Disclosure of Mineral Projects.
Bisie Ridge Regional Exploration Update
Alphamin intensified exploration drilling on the 13km long Bisie Ridge from Q3 2022 to test highly
anomalous soil, geophysical and structural targets identified during 2021. 8,773 metres of the
10,000 metre Phase 1 diamond core programme have been completed along the Ridge, with the
remainder due for completion in Q1 2023.
Although anomalous mineralisation has been confirmed in drilling on the Ridge, it is not of the
obvious coarse visual cassiterite type frequently seen in drillcore from Mpama North and South.
Only ~25% of assays have been returned from the independent laboratory to date from the Ridge
drilling. Assay results when received will support a fuller investigation into the regional setting,
along with data from the on-going geophysical downhole surveys, structural investigations and
