South32’s SA manganese production decreased by 14%
South32’s South Africa Manganese saleable ore production decreased by 14 percent (or 309kwmt) to 1,878kwmt in FY20 as South32 responded to weaker market conditions during H1 FY20, reducing its use of higher cost trucking and undertaking an extended maintenance shut at its underground Wessels mine.
Both the open pit Mamatwan and underground Wessels mines were placed on temporary care and maintenance during the nationwide COVID-19 lockdown in the June 2020 quarter, before returning to full capacity when lockdown restrictions were lifted.
Manganese alloy saleable production decreased by 23 per cent (or 16kt) to 53kt in FY20 as South32 completed the strategic review of its alloy business prior to placing the Metalloys smelter on care and maintenance in July 2020.
South32’s South Africa Manganese consists of two manganese mines and the Metalloys manganese alloy smelter which was placed on care and maintenance in July 2020.
Hotazel Manganese Mines (HMM) is located in the Kalahari Basin. South32 holds a 60 per cent interest in Samancor Holdings (Pty) Ltd and Anglo American Plc holds the remaining 40 per cent. Samancor indirectly owns 74 per cent of HMM, which gives South32 its ownership interest of 44.4 per cent. The remaining 26 per cent of HMM is owned by B-BBEE entities.
South32 holds an effective 60 per cent interest in Samancor Manganese (Pty) Ltd (Metalloys manganese smelter).
FOB manganese ore Operating unit costs decreased by 16 per cent in FY20 to US$2.25/dmtu as a weaker South African rand, lower price-linked royalties and the one-off benefit from settling a historical royalty claim more than offset lower sales volumes.
Manganese alloy Operating unit costs increased by 16 per cent in FY20 to US$1,364/t in-line with the decline in sales volumes.
Underlying EBIT decreased by 71 per cent (or US$134 million) in FY20 to US$54 million as lower average realised prices (-US$130 million) and reduced sales volumes (-US$81 million), were partially offset by a weaker South African rand (+US$20 million), lower price-linked royalties (+US$16 million), and reduced activity delivering lower spend on the opportunistic trucking of ore (+US$16 million), contractors (+US$10 million) and maintenance (+US$5 million).
South32 average realised price for external sales of South African ore was a six per cent discount to the medium grade 37 per cent manganese lump ore index (FOB Port Elizabeth, South Africa) in FY20 as the contribution of its lower quality fines product increased (FY20: 13 per cent, FY19: six per cent) in response to market conditions throughout the year.
Sustaining capital expenditure decreased by US$7 million in FY20 to US$23 million with the Metalloys smelter placed on care and maintenance.
