International Resources Holding (IRH), a subsidiary of the Emirati conglomerate International Holding Company (IHC), just sealed a deal to acquire almost 100% of Tremont Master Holdings. Valued at C$503 million–around US$367 million–the deal will give IRH indirect control of 56% of Alphamin Resources. The latter owns the Bisie tin mine, the largest tin mine in the Democratic Republic of Congo (DRC).

According to Bloomberg, an IRH delegation visited the DRC last November to conduct a due diligence mission. Although the offer is lower than Alphamin's current capitalization on the Toronto Stock Exchange, Denham Capital, Tremont's sole shareholder, stands to gain. The American fund previously held 57% of Alphamin.

Located in North Kivu, the Bisie project has developed in a difficult security environment. Alphamin has held an 80.75% stake since 2012, when the tin market was still uncertain. The remainder of the capital is divided between the South African state-owned company IDC (14.25%) and the Congolese state (5%). Between 2019 and the end of 2024, the mine generated cumulative sales of $2.3 billion for a gross margin of $689.5 million. The company paid $115 million in dividends in 2022-2023, and expects a payment of $70 million in October 2025 in respect of fiscal 2024.

The transaction is still subject to prior authorization by the Congolese authorities. Under article 178 bis of the revised Mining Code, any indirect transfer of mining rights must be approved by the State, on pain of nullity. A transfer fee, previously set at 1% of the transaction value, is also payable.

For IRH, this acquisition is part of a broader strategy to build up a portfolio of critical mining assets. According to Africa Intelligence, the group is also in discussions with Gécamines to obtain new permits in the DRC, although this information has not yet been confirmed. Alphamin is also studying other expansion projects in the country.

This operation illustrates the Emirates' growing interest in transitional minerals. Saudi Arabia has stepped up diplomatic exchanges with Kinshasa around a framework for sustainable supply chains. Dubai remains one of the major outlets for Congolese artisanal gold, as the Governor of South Kivu recently reminded us. By 2023, collaboration between the Emirati group Primera Gold and the Congolese government had led to a surge of over 12,000% in gold channeled through the Primera Gold DRC joint venture.
