What SIMEC does

SIMEC Mining operates the Tahmoor Coal underground mining operation in the Wollondilly region of New South Wales, Australia, approximately 95km southwest of Sydney. The mine extracts premium-quality hard coking coal (metallurgical coal) from the Bulli coal seam, a critical input material for steelmaking processes. SIMEC operates as a division within GFG Alliance, a privately-held diversified industrial conglomerate whose other major brands include LIBERTY Steel, INFRABUILD, and ALVANCE. The parent-conglomerate structure provides potential for vertical integration across the steel value chain, with SIMEC supplying coking coal upstream of GFG's steelmaking operations.

The operation has regulatory approval to produce up to 4 million tonnes of Run of Mine (ROM) coal per annum and operates 24 hours a day, employing approximately 600 employees and contractors who support local and regional businesses in the Wollondilly Shire area. The extracted coal is transported via rail from the mine to Port Kembla, where it is distributed to both Australian domestic steel industry customers and international export markets. SIMEC's business model centers on the extraction and direct sale of a single commodity product — hard coking coal — to enterprise buyers in the steelmaking sector, using direct-to-consumer (B2B) sales motion rather than intermediary distribution.

With over 40 years of operational history at the Tahmoor site, SIMEC has accumulated domain specialization in the Bulli seam's geology and mining techniques. The business has received Independent Planning Commission (IPC) conditional approval for the Tahmoor South expansion, signaling intent to extend production capacity. Pricing is not publicly disclosed, consistent with negotiated bulk-commodity contracts typical of metallurgical coal markets. Customer concentration specifics are not publicly detailed beyond the dual domestic/export split.
