IDC to sell 10.2% equity stake in Rössing uranium mine

South Africa’s Industrial Development Corporation (IDC) has formally moved to sell its 10.2% equity stake, citing the expiry of its investment horizon.

In a recent Expression of Interest (EOI), the IDC said it intends to dispose of its shareholding in Rössing Uranium Limited, noting that the investment holding period has expired. The notice does not cite operational or performance concerns, but frames the sale as part of the development financier’s normal investment cycle.

“The IDC has now reached its investment horizon and intends to dispose of its 10.2% stake,” the notice states. “IDC intends to dispose of its shareholding in the company because the holding period for investments has expired.”

The IDC was one of Rössing’s founding shareholders when the uranium mine began operations in the 1970s, at a time when Rio Tinto was the dominant shareholder and operator. Rössing has since become one of Namibia’s longest-running mining operations and a cornerstone of the country’s uranium industry.

Rössing’s ownership structure has evolved significantly over time. In 2018, Rio Tinto sold its majority stake to China National Uranium Corporation (CNUC), which currently holds 68.6% of the shares.

The Iranian government has owned 15% of Rössing since 1976, while the Namibian government holds a 3% equity stake. Despite this, Namibia retains 51% of the mine’s voting rights. Local individual shareholders hold the remaining shares.

Through the EOI process, the IDC has invited interested buyers to submit written expressions of interest to acquire the 10.2% stake. Prospective investors are required to provide a detailed company profile, including information on ownership, governance structures and current management.

The IDC has also stipulated that potential buyers must align with its development objectives and submit a strategic rationale explaining their interest in Rössing and the intended purpose of the acquisition.

Interested parties must further demonstrate their financial capacity to complete the transaction and provide proof of the necessary approvals from their supervisory boards or equivalent governing bodies.

The sale opens the door for either an existing shareholder to consolidate its position or for a new strategic or institutional investor to enter one of Namibia’s most established uranium operations, at a time when global interest in nuclear energy is strengthening.

The IDC has not disclosed a valuation or timeline for concluding the transaction, indicating that the disposal process will be guided by the quality and suitability of bids received through the EOI process.
