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 guidelines[1], 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 Plan[3].

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 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 Mtpa[5];

§ 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 ZAR18.83[6] 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 previously[9], 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 Company[10]. 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:

"The Makhado Project continues to progress on schedule in preparation for first coal 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."

Table 3: Capital Expenditure Estimate

Table 4: Operating Margins Parameters

Table 5:Comparison of LOM Plan (June 2023) to Scenario 2 Plan (August 2022)

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.

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).
