Approximately 75% of the World's platinum supply comes from the large (65,000 km2) Bushveld Igneous Complex in South Africa. Platinum and associated metals, the platinum group elements (PGEs), are mined on the eastern and western limbs of the intrusion.  This mining is at an advanced stage with deep mines on narrow reefs. The methods used are labour intensive and expensive which, when combined with the current volatile price of platinum, are impacting on the mines profitabilitiy and is forcing companies to search for more viable options elsewhere.

My research focuses on PGE-mineralisation on the northern limb, known as the Platreef, which is amenable to low cost open-pit and mechanised underground mining methods due to the greater thickness of the mineralised interval. From detailed petrological and geochemical studies I hope to characterise this different style of PGE-mineralisation and attempt to understand its genesis and relationship to the eastern and western limbs.
