- Harmony Gold Mining Company Limited is a leading gold producer primarily engaged in underground and surface gold mining, processing, and exploration; it also produces silver, uranium, and copper as by-products. Founded in 1995 through the unbundling of assets from Randgold & Exploration Company Limited and headquartered in Johannesburg, South Africa, the company operates nine underground mines, one open-pit mine, and several surface retreatment operations in South Africa, including high-grade assets such as Moab Khotsong, Mponeng (the world's deepest gold mine), Tshepong North, Tshepong South, Doornkop, Joel, Target 1, Kusasalethu, and Masimong; surface operations at Mine Waste Solutions, Phoenix, Central Plant Reclamation, Savuka, and Kalgold; the Hidden Valley open-pit gold and silver mine in Papua New Guinea through a 50% interest in the Morobe Mining Joint Venture; and the Wafi-Golpu copper-gold development project in Papua New Guinea. In Australia, Harmony holds the Eva Copper project in Queensland, acquired in 2022 for copper diversification, along with Rosby exploration tenements; the company markets its primary output of gold doré bars to global refiners, central banks, and commodities markets, targeting sustained production of approximately 1.4 million ounces annually from its South African and Papua New Guinea operations. Harmony's geographic footprint spans South Africa (Witwatersrand Basin and Kraaipan Greenstone Belt), Papua New Guinea (New Guinea Mobile Belt in Morobe Province), and Australia (Mt Isa Inlier, Queensland), serving international markets with a workforce exceeding 45,000 across its segments. Recent major developments include the completion in October 2025 of its R18 billion (US$1.01 billion) acquisition of MAC Copper, securing the high-grade CSA copper mine in Australia to accelerate diversification into copper and support energy transition metals; ongoing advancement of the Eva Copper project with updated feasibility studies and drilling; extension projects at Moab Khotsong's Zaaiplaats and Mine Waste Solutions' Kareerand tailings; renewable energy rollouts for low-carbon operations; record FY25 adjusted free cash flows and 10th consecutive year meeting production guidance; and its 75th anniversary milestone as it transitions into a globally competitive gold-copper producer.
