Mine Life25 years (as of Jan 1, 2022)
The Magdalena bituminous mine is an underground mining operation that recommenced small-scale mining activities during 2020 after it was placed on care and maintenance on October 31, 2018. These mining activities were suspended at the end of Q3 2020 due to a lack of a reliable and economically attractive market for the Buffalo’s bituminous coal at the time. Small scale mining activities, targeting monthly production of 8,000 tonnes per month, resumed in February 2021 following renewed interest in the bituminous coal.

Black Economic Empowerment(B-BBEE Commission) 30 % Indirect
Buffalo Coal Corp. 70 % Indirect
Zinoju Coal (Pty) Ltd. (operator) 100 % Direct
Buffalo Coal Corp. owns a 100% interest in Buffalo Coal Dundee Proprietary Limited (“BC Dundee”), a South African company with an interest in two coal mines, the Aviemore East anthracite mine, an underground mining operation, and the Magdalena bituminous mine.

BC Dundee indirectly holds a 70% interest in the BC Dundee Properties through its 70% interest in Zinoju Coal Proprietary Limited (“Zinoju”), which holds all the mineral rights with respect to the BC Dundee Properties. The remaining 30% interest in Zinoju is held by South African Black Economic Empowerment ("BEE") partners.

Summary:

The Magdalena area surface geology is dominated by the coal-bearing Vryheid Formation (Pv) and Karoo aged dolerites . The Vryheid Formation is present within the northern and eastern portions of the mine properties and sub-outcrops along the boundaries of the exposed dolerite. Dolerite is exposed over the central and western parts of the study area as a plateau formed by a dolerite sill. Large portions of the farms Mount Johanna, Slieve Donald and Mourne are capped by the 30 m to 50 m thick Ingogo dolerite sill which has a transgressive undulating split from its base. The sill is broken by erosion to the northeast along a cliff-faced scarp with steep boulder strewn slopes. Dolerite dykes are masked below the plateau and have only been located where exposed along the scarp flanks and in underground workings. A widely spaced dolerite dyke network with intrusive thicknesses varying between 0.5 m to 15 m is present. Although a 6 m displacement has been encountered during mining activities, the mining environment has been fairly stable without any major displacements. The displacement was extrapolated towards the western boundary for the purpose of creating a geological model. More drilling will be required to determine the strike and length of this displacement. The current borehole spacing makes it impossible to accurately predict the existence of a fault. The main coal seams locally identified within the Magdalena Colliery project area are named the Alfred and Gus coal seams ........

Summary:

Magdalena Colliery is an underground bituminous mine supplying raw coal from the Alfred and Gus seams to the on-site Coal Handling and Preparation Plant (CHPP) washing facility. Magdalena consists of a defunct opencast mining area (ceased operations March 2015) and numerous adits that provide access to the target Alfred and Gus coal seams in the area. Mine access is currently through an adit complex (men and material, coal clearance by conveyor and intake ventilation main fans). The Alfred seam height varies between 1.5 m to 2.3 m with minimal mining dilution. The Gus seam height similarly varies between 1.5 m and 2.2 m. When the parting between the two seams is <=0.5 m the combined seam height varies from 3.5 m to >5.0 m. Depth of cover increases from north to south with the majority of the current mine plan being shallower than 140 m below surface. The mine currently employs the conventional drill and blast, bord and pillar mining method utilizing conventional mining equipment, handheld coal drills for coal production and roof support, and battery powered scoops (previously a continuous miner operation). Currently mining is in progress utilising a small mine team at Magdalena. In June 2022, the mine will start to ramp up production to a full section, increasing ROM production to 20,000 tpm from July 2022 until December 2023. In January 2024, an additional (second) conventional drill and blast section will be employed, increasing production for the next 10 years to some ........
