In several SEC Form 6‑K reports, Harmony notes that gold remains its core business while it expands into copper to enhance its portfolio and diversify its operating footprint. The company refers to itself as a global gold and copper producer and highlights operations and projects in South Africa and Australia, including references to high-grade underground mines and open-pit developments.

According to Harmony’s filings, the company is headquartered in South Africa and maintains a growing international operational footprint. Its shares are listed on the Johannesburg Stock Exchange, and it also has a New York Stock Exchange share code HMY referenced in its operational update, indicating that it files annual reports on Form 20‑F with the SEC. Harmony confirms in a Form 6‑K dated 3 November 2025 that it filed its annual report on Form 20‑F for the year ended 30 June 2025 with the SEC.

Business focus and commodities

Harmony’s regulatory disclosures emphasise that gold is its core commodity, and that it is expanding into copper. In its operational update for the three months ended 30 September 2025, the company explains that copper expansion is a strategic move to enhance portfolio resilience, margin quality and long-term sustainability. It also notes that copper is essential to the global shift toward renewable energy infrastructure and that its growing copper portfolio reinforces its role in enabling the energy transition.

In a Form 6‑K dated 24 November 2025, Harmony announces the completion of an updated feasibility study and a final investment decision for the Eva Copper Project in Northwest Queensland, Australia. The company describes Eva Copper as a 100%-owned asset designed as a low strip ratio open-pit development that will process ore over a multi‑year mine life. Harmony states that Eva Copper, together with its MAC Copper acquisition, is expected to provide meaningful copper exposure alongside its significant gold production, contributing to a diversified mix of gold and copper.

Geographic footprint and projects

Harmony’s filings reference operations and projects in several regions. The company is incorporated and based in South Africa and refers to its South African operations, including underground mines such as Mponeng and Moab Khotsong, and other assets that contribute to its gold production. It also refers to Hidden Valley, which it describes as a long‑running operation that has operated for many years without a loss of life, and to life‑of‑mine extension projects at Mponeng, Moab Khotsong and Hidden Valley.

In Australia, Harmony’s filings describe two key copper‑related assets: the MAC Copper acquisition, which includes the high‑grade CSA copper mine in Cobar, and the Eva Copper Project in Northwest Queensland. Harmony states that these Australian copper assets are expected to provide substantial copper production once fully commissioned and that they strengthen the company’s long‑term copper exposure and growth profile in what it calls a Tier 1 mining jurisdiction.

Reporting, governance and listings

Harmony files regular reports with the SEC as a foreign private issuer. Its Form 6‑K filings indicate that it files annual reports under cover of Form 20‑F and that it maintains listings on the Johannesburg Stock Exchange (share code HAR) and references a New York Stock Exchange share code HMY in its operational update. Harmony’s 6‑K filings also describe the publication of an annual reporting suite, including an integrated report, sustainability report, operational report, financial report, mineral resources and mineral reserves report, climate action and impact report, remuneration report and notice of electronic annual general meeting.

The company’s governance disclosures in its 6‑K filings include information on its annual general meeting, voting results on ordinary and special resolutions, and the composition of board committees such as the audit and risk committee and the social and ethics committee. Harmony reports that shareholders approved all resolutions at its 2025 annual general meeting and that changes to board committee roles would take effect following that meeting.

Strategy, safety and sustainability themes

Harmony’s operational update for the quarter ended 30 September 2025 outlines several themes that the company presents as central to its strategy. It refers to “Mining with Purpose” and highlights safety, sustainability and operational excellence as non‑negotiable priorities. The company reports on safety metrics such as loss‑of‑life‑free shifts and lost‑time injury frequency rates and notes both positive safety achievements and, in a separate 6‑K, a loss‑of‑life incident at its Mponeng mine, for which it describes initiating a full investigation with the relevant authorities.

In relation to sustainability and transformation in South Africa, Harmony’s filings reference a Broad‑Based Black Economic Empowerment (B‑BBEE) annual compliance report and state that the company remains committed to the transformation agenda in South Africa. The Eva Copper feasibility study announcement also discusses embedded sustainability at that project, including environmental management, local employment and business opportunities, and collaboration with Traditional Owners and local communities in Queensland.

Capital projects and growth orientation

Harmony’s filings describe a focus on long‑life projects and growth initiatives in both gold and copper. The company refers to life‑of‑mine extension projects at key South African and international operations, investment in projects such as a solar power plant to manage energy costs and reduce its carbon footprint, and transformational copper‑gold growth projects including Eva Copper and Wafi‑Golpu. In its operational update, Harmony notes that every project competes for capital and that it applies a disciplined approach to capital allocation, weighing potential returns against associated risks.

Through these disclosures, Harmony positions itself as a mining company centred on gold, with an expanding copper portfolio and a focus on safety, sustainability, and long‑life assets.
