What Metal Concentrators does

Metal Concentrators (MetCon) is a South African precious-metals company headquartered in Centurion, founded in 1989 as Metal Concentrators SA (Pty) Ltd. It operates one of the country's most advanced refineries, with primary facilities in Centurion and Cape Town, and is constructing a third, sustainability-focused site (MetCon SEZ) within the Jewellery Manufacturing Precinct of the OR Tambo Special Economic Zone. The company refines secondary precious metals and jewellers' waste into gold, silver, platinum, and palladium products, and competes across the full precious-metals value chain.

MetCon's product portfolio spans refined bullion (400oz gold and 1kg bars for international markets), patented minted investment bars (Spiral Series, Nguni Gold and Silver, Money Cowries, Ubuntu Gold, Bullion Bear), bespoke jewellery manufacturing services (design through engraving), alloy and findings supply (carated and master alloys, with Legor products added post-Lipman acquisition), and a state-of-the-art laboratory providing certified metal analysis across PGMs and 24+ additional elements. The business serves three primary segments: South African manufacturing jewellers (via a national representative network), individual precious-metals investors (via the wealth.metcon.co.za e-commerce storefront with live LBMA-linked pricing and a guaranteed buy-back at 0-5% margin), and international bullion buyers (via direct sales). Patented heritage lines such as Nguni Gold carry a 0% buy-back margin and function as both investment and gifting products.

Revenue is generated through four mechanics: refining transaction fees, retail spreads on minted bars, professional-services fees for jewellers (casting, finishing, alloys, findings), and bid-ask spreads on guaranteed buy-back trading. The company is privately held and family-owned (Bernard Stern as founder; Grant Crosse as Managing Director as of 2024), with no disclosed institutional investors, funding rounds, or public listing. Competitive positioning is anchored by two regulatory milestones that few SA rivals match: in 2009, MetCon was the first company granted SADPMR and South African Reserve Bank permission to produce and sell minted gold, silver, and platinum bars; in 2013 it became the first South African (and ninth worldwide) member of the Responsible Jewellery Council with dual Code of Practice and Chain of Custody certification. A long-standing platinum supply partnership with Anglo American Platinum (now Valterra Platinum), extended via a 2018 Platinum Partnership Agreement, secures preferential access to a scarce input for the SA jewellery industry. In October 2023, MetCon acquired Lipman & Son, broadening its technical consumables offering to manufacturing jewellers.
