SnapshotThe Vele colliery was placed on care and maintenance in August 2013 due to the global economic downturn coupled with depressed coal prices.

The assessment of outsourcing opportunities resulted in the conclusion of a five-year Contract Mining Agreement (Mining Agreement) with Hlalethembeni Outsourcing Services (Pty) Ltd (HOS) in December 2022. As a result operations were resumed in H1 FY2023 with limited financial and human capital requirements

Ramp-up to full production is expected to occur in H2 CY2023 with HOS targeting monthly production of 60,000t of saleable thermal coal from Vele.

Summary:

The coal deposition of the Vele Colliery occurred within and intra-continental basin bounded by extensional faulting. Major faults have been interpreted, through field observations and geophysics, for the area. The faults divide the deposit in blocks with varying seam depths.

A serious of dolerite dykes trend predominantly east west across the project Colliery area, the largest is estimated to be more than 15m thick. These dykes were emplaced during the extension tectonics that formed the intra continental basin. The dykes did not have significant displacement associated with their emplacement but have resulted in minor de-volatilisation of coal in the immediate contact.

The Top, Middle and Bottom seams were all intersected through drilling and mining activities within the Vele Colliery area. Top and Bottom seams can further be differentiated into a Top Lower, Top Middle, Top Upper, Bottom Lower and Bottom Upper. The Top Middle and Top Upper are not considered economic.

Individual sub-seams can be correlated over the entire area. Correlation is assisted by a distinctly bioturbated marker between the Bottom and Middle seams. The Bottom seam lies directly over the glacial Dwyka-aged sediments or granite-gneiss basement. The coal seams generally dip with no more than 2? north, but can increase to 10? in the vicinity of faults. A series of dolerite dykes occurs in the area and does not appear to have caused any displacement but have devolatilise the coal bordering them.

The dykes did not have significant displacement associated but have resulted in minor de-volatilisation of coal in the immediate contact.

The three coal horizons are interbedded coal and mudstone units with varying coal quantities and qualities. The coal zones can be subdivided into four coal sections or composite seams, namely: Inconsistently formed Top Seam, which is 0 – 7.66m thick and contains 55% to 65% coal The Middle Seam, which is 0 – 2.19m thick and contains 20% to 45% coal The Bottom Upper Seam, which is 0 – 5.48m thick and contains 65% to 80% coal The Bottom Lower Seam, which is 0 – 7.87m thick and contains 65% to 80% coal

The deposits outcrops in the east and the southern part of the deposit. The coal seams have been removed during post Karoo erosion towards the south. The seams occur in blocks with different seam floor and roof elevations due to the prevalent faulting within the area. The faulting divided the deposit into opencast minable coal and underground exploitable coal sections. The deposit covers an area of 4 502.7ha and the floor of the Bottom Lower seam varies between 340m amsl and 480m amsl.
