                      MAKHADO PROJECT – SIGNIFICANT INCREASES IN MINE LIFE AND COAL RESERVES

                 MC Mining Limited (MC Mining or the Company) is pleased to announce the results of the
                 updated Life of Mine (LOM) plan and Coal Reserve estimate for its fully-licensed and shovel-
                 ready Makhado steelmaking hard coking coal project (Makhado Project, Makhado or the
                 Project).

                 Highlights:
                 • the updated LOM plan2 demonstrates a significantly increased mine life (+27%), at a
                     higher annual mine production rate (+25%) and results in robust project financial
                     returns, whilst using updated conservative cost, macro-economic and coal price
                     assumptions;

                  •    Proved and Probable Coal Reserves estimates, reported in accordance to JORC Code
                       guidelines1, have substantially increased (+53%, from 69 to 106 million tonnes (Mt)2)
                       as a result of the detailed mine designs completed for the East Pit deposit in
                       preparation for mine start; and
                  •    steady progress has been made with critical early works activities in line with the
                       Project’s Implementation Plan3.

                 The LOM plan builds on the recently completed five-year Implementation Plan that envisaged
                 initially mining the East Pit. The plan incorporates the exploitation of all portions of the East,
                 Central and West coal deposits that are mineable by surface mining methods. The Coal
                 Reserve estimate is derived from this updated LOM plan that applies updated costs, macro-
                 economic and coal price assumptions.

                 The updated LOM plan and Coal Reserve estimate are required to conclude funding

1
    In accordance with ASX Listing Rule 5.21 and Appendix 5A (the JORC Code) under the supervision of a Competent Person.
2
    Conpared to the 30 August 2022 announcement, Coal Reserves increased 53%, saleable steelmaking HCC increased 64% and saleable TC
increased by 57%.
3
    Refer to Company announcement of 26 April 2023 Makhado Project Update.
                 discussions that are part of the ongoing implementation of the Makhado Project mine-build.
                 The Project is 67.3%-owned by MCM through a local subsidiary, Baobab Mining & Exploration
                 Pty Ltd (BM&E). All figures are reported for the full project in US$ and ZAR.

                 •      The updated LOM plan is a significant improvement on the Scenario 2 plan completed
                        in August 2022 to a pre-feasibility level of confidence (Scenario 2)4, as is demonstrated
                        by:

                            o     improved production metrics:
                                     ▪ a 25% increase in the targeted rate of mining from 3.2 to 4.0 million (M)
                                         tonnes per annum (Mtpa) run-of-mine (ROM) coal; and
                                     ▪ a 100% increase in coal handling and processing plant capacity, from 2.0
                                         to 4.0 Mtpa; resulting in
                                     ▪ a 30% increase in planned annual sales of 64 Mid Volatile (Vol)
                                         steelmaking hard coking coal (HCC) to 0.81 Mtpa and a 15% increase in
                                         planned annual sales of 5,500 kcal thermal coal (TC) to 0.62 Mtpa5;
                                     ▪ a 60% increase of total salable coal products from 26 to 41 million tonnes
                                         (Mt) over the mine life;
                                     ▪ a 27% increase in the LOM from 22 to 28 years; and
                                     ▪ the time to first production increasing from 12 to 18 months due to the
                                         new plant build whilst keeping the payback period materially unchanged
                                         at 3.5 years from the start of construction.

                            o     using updated and conservative cost and macro-economic assumptions that
                                  account for recent inflationary and market cost escalations in key production
                                  inputs, these being:
                                      ▪ a 6% increase in estimated fully-allocated costs (C3) to average US$83
                                           (ZAR1,563) per tonne of saleable coal over the LOM;
                                      ▪ an 11% increase in the estimated project peak funding requirements to
                                           US$96 M (ZAR1.8 billion (Bn));
                                      ▪ a 22% increase in the forecast ZAR:US$ foreign currency exchange
                                           (Forex) rate from ZAR15.47 to average ZAR18.836 over the LOM;
                                      ▪ a marginally higher indexed premium HCC price forecast from US$212 to
                                           US$215 per tonne sold on a free on board basis (FOB)7 over the LOM,
                                           sourced from independent advisors Afriforesight; and
                                      ▪ a marginally higher indexed API4 thermal coal price (6,000 kcal) forecast

                                           from US$106 to US$108 per tonne (FOB)8 over the LOM.

                           o    resulting in the following planned financial returns for the Project:
                                    ▪ a 20% improvement in free cashflows to US$936 M (ZAR17.6 Bn);
                                    ▪ a 17% increase in the post tax Net Present Value (NPV) from ZAR5.8 Bn
                                        (real, post-tax, at a 6% discount rate) to ZAR6.8Bn (due to exchange rate
                                        movements, a 4% reduction in US$ terms to US$361 M); and
                                    ▪ an internal rate of return (IRR) (real, post-tax) of 37% and EBITDA margin
                                        of 30%.

                •      Proved and Probable Coal Reserves estimates, reported in accordance to JORC Code
                       guidelines, have substantially increased compared to the estimates reported
                       previously9, to result in:
                          o a 53% increase in total Coal Reserves from 69 to 106 Mt due to the revision in the
                              East Pit optimisation and mine design;
                          o a 64% increase in salable steelmaking HCC from 13.7 to 22.5 Mt achieved at an
                              overall yield of 21.2%; and
                          o a 57% increase in salable TC from 11.9 to 18.7 Mt achieved at an overall yield of
                              17.6%.

                       The Coal Resource estimate on which this Coal Reserve estimate is based remains
                       unchanged at 296 Mt of mineable tonnes in situ (MTIS) in the Measured and Indicated
                       categories as previously announced by the Company10. The reported Coal Resource is
                       inclusive of the Coal Reserve.

                •      Steady progress has been made with critical early works activities in line with the
                       Implementation Plan, to advance the Project towards commencement of production,
                       including:
                          o commencement with works relating to the power supply overhead transmission
                              line;
                          o construction of a bridge across the Mutamba river to provide access to the
                              project site;
                          o order placement for key long-lead items; and
                          o progressing with the selection of mine-operating contractors.

                Chief Executive Officer, Mr. Godfrey Gomwe, commented:

production to no later than 18 months after construction starts. We are pleased to see a
substantial increase in our Coal Reserves and consequently mine life at a much-improved
annual production rate for saleable coal products. This bodes well for moving operations down
the cost curve whilst aiming to take advantage of the near-term steelmaking HCC coal price
boons. We continue to focus on advancing early works activities whilst funding activities are
concluded in H2 CY2023, so that mine commissioning meets scheduled [production?]
timelines. We are also excited to have strong contenders to be our partner mining contractors
and partner coal beneficiation plant operating contractors in the managed tender processes
currently under way and due for completion during the third quarter of 2023.”

The NPV is most sensitive to variances in the USD:ZAR Forex rate, HCC price and HCC yields.
The NPV increases by 45%, 35% and 25%, respectively, when the USD:ZAR Forex rate, HCC
price and HCC yields are each increased by 10%. Conversely, the NPV is less sensitive to
changes in mining operating costs and product trucking costs. The NPV decreases by 12%
and 9% when mining costs and product trucking costs are increased by 10% respectively.

The break-even indexed premium HCC and API4 TC (6,000 kcal) prices, where the NPV is zero,
were calculated to be US$171/t and US$86/t, respectively at the production ratios presented
in the LOM Plan.

The LOM Plan is an improvement, in many aspects, on the project development scenario
selected in August 2022 (Scenario 2) as the preferred plan to be taken forward. Whilst the
Scenario 2 plan was compiled at a pre-feasibility level of confidence (±30%), the LOM plan
has been prepared with capital cost estimates within a ±10% accuracy level for the first five
years of the project and thereafter within ± 30%. The capex for the first five years, exluding
any sustaining capex, is ZAR1.7Bn to construct the Makhado Project (±10% accuracy) while
LOM plan includes a further ZAR0.5Bn (±30% accuracy) to develop the Central and West pits.
The reference date for the cost estimates is April 2023.

CRITICAL EARLY WORKS IMPLEMENTATION PROGRESS
The Company continues with critical early works being:
     •     commencement with detailed design, procurement and construction of the power
           supply overhead transmission line, with construction team now mobilised onsite - a
           critical path activity;
     •     refurbishment of onsite accommodation to house project construction crews;
     •     placement of orders for key long-lead time items;
     •     progress with the managed tender processes for selecting contractors to partner as
           the lead mining and coal beneficiation plant operating contractors;
     •     mobilisation of construction contractors for the construction of the main access road,
           main bridge and civil works for bulk water reticulation; and
     •     progress with erection of fencing to secure the project site.

  Notes
  1.      GTIS based on a 1.4 washability
  2.      MTIS excludes the Fripps Farm and is limited to the 200 m depth cut-off.
  3.      MTIS includes geological losses of 5% on Measured, 8% on Indicated and 10% on Inferred Coal Resources.
  4.      Quality parameters applied to GTIS to obtain MTIS.
  5.      Minimum coal seam thickness of 0.5 m applied.
  6.      HCC Ash content ≤ 10%, TC Ash content ≤ 25.9% and Volatile material > 20%.
  7.      The Coal Reserve estimation includes diluted Measured and Indicated Coal Resources only.
  8.      No Inferred Coal Resources have been included in the Coal Reserve estimation.
  9.      The Coal Reserve estimate was completed using a realised coal price of US$193t for 64 Mid Vol HCC (export) and US$29/t
          for TC 5,000 kcal after product quality discounts and offtake-related deductions were applied.


  Key Assumptions and JORC Code Requirements
  Coal Resources are reported inclusive of Coal Reserves.

  The coal price assumptions used to estimate Coal Reserves were indexed values of US$215/t
  for steelmaking premium HCC and US$108/t for API4 Thermal Coal (6,000 kcal), on a real
  basis. The corresponding realised coal prices for two salable products after making quality
  and sales price adjustments were US$193/t for the 64 Mid Vol HCC for export and US$29/t
  for the TC 5,500 kcal at an assumed ZAR:US$ Forex rate of ZAR18.83. The long-term indexed
  coal price forecasts were sourced from Afriforesight and the Forex rate assumptions were
  sourced from ABSA Bank Ltd as of June 2023.

  The Coal Resources and Coal Reserves have been classified in accordance with the guidelines
  set out in the Australasian Code for Reporting Exploration Results, Mineral Resources and Ore
  Reserves, published by the Joint Ore Reserves Committee (JORC), of the Australasian Institute
  of Mining and Metallurgy, the Australian Institute of Geoscientists and the Minerals Council
  of Australia, December 2012 (the JORC Code or JORC 2012).

  Material Information for the Makhado Project coal deposit, including a summary of material
information pursuant to ASX Listing Rule 5.9 and the Assessment and Reporting Criteria in
accordance with JORC 2012 requirements in the body of this anouncement, may be found on
the Company’s website:

Coal Resources and Coal Reserves Governance Statement
In accordance with ASX Listing Rule 5.21.5, governance of the Company’s Coal Resources and
Coal Reserves development and management activities are through the management and
owner’s team for MCM.

Senior geological and mining engineering staff contracted by MCM oversee reviews and
technical evaluations of the estimates and evaluate these with reference to industry
standards and empirical estimates for physical, cost and performance measures. The
evaluation process also draws upon internal skill sets in operational and project management,
coal processing and commercial/financial areas of the business.
The MCM Safety, Health, Environment and Technical Committee (SHETech Committee) is
responsible for monitoring the planning, prioritisation and progress of the estimation and
reporting of Coal Resources. These definition activities are conducted within a framework of
quality assurance and quality control protocols covering aspects including drill hole siting,
sample collection, sample preparation and analysis as well as sample and data security. The
SHETech Committee is responsible for the reporting of Coal Reserves.

A four-level compliance process guides the control and assurance activities by the SHETech
Committee, being:
•    provision of Company policies, standards, procedures and guidelines;
• Coal Resources and Coal Reserves reporting based on well-founded geological and
     mining assumptions and compliance with external standards such as the JORC Code;
•    internal and third-party reviews of process conformance and compliance; and
•    internal and third-party assessment of compliance and data veracity.

The Company reports its Coal Resources and Coal Reserves, as a minimum, on an annual basis
and in accordance with ASX Listing Rule 5.21 and clause 14 of Appendix 5A (the JORC Code).
Competent Persons named by the Company are either members of the South African Institute
of Mining and Metallurgy or the South African Council for Natural Scientific Professions, which
are ‘Recognised Professional Organisations’ (RPOs), included in a list promulgated by the ASX
from time to time, hence qualify as Competent Persons as defined in the JORC Code.

Comparison of Coal Reserves Estimates
Tables 6 to 9 compare the 2022 Coal Reserves estimate with the updated Coal Reserve
estimate as at 28 June 2023. Changes in the Coal Reserves are due to the revision of pit
optimisations and detailed mine designs of the East Pit. MCM’s equity share is 67.3% of the
  Coal Reserves estimate shown below. Coal Reserves are included in the Coal Resource
  estimate.
