ARM Andalusite (Pty) Ltd

What ARM Andalusite (Pty) Ltd does

ARM Andalusite (Pty) Ltd is a privately held South African mining company that operates a single open-cast free-dig mine on the Maroeloesfontein deposit near Thabazimbi, Limpopo, producing andalusite — a naturally occurring alumina-silicate mineral (Al2O3 ≥57%, Fe2O3 ≤1%) used primarily as a high-temperature refractory raw material. The company's predecessor, Andalusite Resources (Pty) Ltd, was established in 2001 with first production in 2003; it entered business rescue in 2019 and the assets were acquired by ARM Andalusite in May 2022 under new directorship, followed by a rebrand and a capacity rebuild from a historical 1,600 tons/month to 6,000 tons/month. Products include raw andalusite in multiple size grades (0–1mm, 0.5–1.6mm, 1–3mm, 2–5mm), milled powders down to 2 micron flour, Marlusite and Milled Marlusite variants, and by-products (magnet rejects, andalusite dust).

The company sells B2B directly to industrial refractory manufacturers worldwide, with the iron and steel industry as the primary end-market and aluminium, cement, foundry, and glass industries as secondary segments; distribution is supported by shipping access via Durban port. Revenue is generated through one-time sales of raw, milled, and by-product mineral streams, with pricing not publicly disclosed and quotes handled via direct engagement. A key technical and commercial differentiator is that andalusite requires no calcining before use, yielding a smaller carbon footprint and lower energy cost than competing refractory aggregates. ARM Andalusite also reports compliance with South Africa's Broad-Based Socio-Economic Empowerment Charter (achieving over 26% Black ownership) and operates Social and Labour Plan community projects (Farming and Brick Manufacturing via the Aganang Cooperative), underpinning its mining right and social license to operate.
