Snapshot	The Masama Coal Mine has exceptional coal qualities, specifically low ash and sulphur, accessible through economical stripping ratios. The mine has access to a nearby rail siding, road and water infrastructure, and enjoys closer proximity to certain target markets relative to other coal producers in the region. Masama has estimated coal resources for the E and A Coal Seams in the Mining Licence and Prospecting License areas. The Masama coal mine was temporarily shutdown between October 2023 and March 2024 as Minergy transitioned to the new mining contractor. A new mining contractor was engaged in December 2023, and production resumed in February 2024, with the first feed to the plant in April 2024, after a four-month production hiatus. Coal sales have resumed, albeit with low volume and smaller customer base. However, all indications are that some old customers are returning, and the new customer pipeline is attractive.

Summary:

Masama Coal Mine is located within the Mmamabula Area of the Southern Belt of the Central Kalahari Sub-Basin of Botswana. The Mmamabula Coalfield is contiguous with and forms the western extension of the Waterberg Coalfield of South Africa.

Geologically the Masama Coal Mine area is underlain by coal, coaly mudstone and sandstone of the Mmamabula Formation of the Ecca Group of the Karoo Supergroup.

Only occasional outcrops of the Ecca Group mudstones and sandstones have been observed in the field. In the West Block of the Masama area, Kalahari Sands regionally ranges in thickness from 0 m to 15 m and in the Coal Resource area the sand cover is generally in the region of 5 m to 10 m thick.

Five major coal seams and a coal sequence are developed in the Masama Coal Mine area. These seams are named from the base upwards as, the E Seam, A Seam, A Sequence, A Upper Seam, K Seam and G Seam. The deposit types found within the project area represent strata bound coal seams of various thickness and quality.

The strata in the Masama Coal Mine area are generally flat, dipping gently at 1 to 3° away from sub outcrop areas. A few faults, trending northeast-southwest and northwest-southeast, were identified by Shell and more recently by GM Geotech. The southern boundary of the coal-bearing Ecca Group with the Waterberg Group is interpreted as a faulted-contact.

Coal resources were only estimated for the E, A Coal Seams in the Mining Licence and Prospecting License areas.

The A Seam represents the primary target for opencast mining in the Masama Coal Mine area and consists of a robust coal seam at the base of a thicker coal and carbonaceous mudstone sequence. The A Seam has been developed consistently in the project area and consists of interbedded bright and dull coal often with large (centimetre scale) pyrite nodules present.

In the Coal Resource area, the thickness of the A seam is generally greater than 1.2 m up to 5.9 m with an average thickness of 4.7 m. The A Seam is generally of good quality, with an average coal quality of 19.4% Ash (air dried) and CV of 22.7 MJ/kg.

The E Seam represents the lowermost robust coal seam in the succession and is dominated by alternating bright and dull coal layers. In some places, minor sandstone partings are present in the E Seam. The E Seam is high quality coal and represents an opencast and underground mining target. The E Seam can be mined opencast after opencast mining of the A Seam in the same area.

The E Seam in the Coal Resource area consists of a single seam ranging from 0.4 m to 2.8 m thick with an average thickness of 1.7 m. The E Seam has an average coal quality of 23% Ash (ad) and CV of 22 MJ/kg.

The A Upper Seam represents the thin layers of a bright/dull coal at the top of the Middle Mmamabula coaly mudstone unit. Where the A Upper Seam is developed within the Coal Resource area the thickness is very consistent ranging from 1.1 m to 2.3 m with an average thickness of 1.2 m. The A Upper Coal Seam has an average coal quality of 32% Ash (ad) and CV of 18.8 MJ/kg. No Coal Resources are estimated for this seam.
