The proposed merger between Teck Resources and Anglo American, which aims to create a new entity called Anglo Teck, faces a significant challenge from Glencore, a co-owner of the massive Collahuasi copper mine in Chile. While the merger agreement doesn't mention Glencore, the Swiss commodities giant is a key stakeholder whose cooperation is crucial for the deal to proceed. The primary driver for the Anglo-Teck merger is the potential synergy between Teck's Quebrada Blanca (QB) and Anglo's Collahuasi copper mines, located just $11$ kilometers apart in the Andes. Combining these operations is projected to boost collective operating income by $1.4$ billion annually.
The complex ownership structure of these mines presents a major hurdle. Teck owns $60$% of QB, with Sumitomo holding $30$% and Chile's Codelco $10$%. Collahuasi, on the other hand, is $44$% owned by Anglo, $44$% by Glencore, and $12$% by Mitsui. This means Anglo and Teck must negotiate with four other shareholders. Glencore, known for its aggressive negotiation tactics, holds significant power over Collahuasi's future, comparable to Anglo's.
The strategic plan involves building a conveyor belt to transport Collahuasi's richer ore to QB's mill, maximizing efficiency and boosting copper output by an estimated $175,000$ tonnes per year. Collahuasi's ore grade is $0.96$% copper per tonne, almost double QB's $0.52$%. A logical merger structure would involve a joint venture owned by all shareholders, with Anglo Teck having the largest stake. However, valuing the individual equity stakes of all six partners, particularly given QB's significant cost overruns and lower ore grade, will be contentious. Glencore is expected to leverage QB's challenges to minimize its valuation and maximize its own equity stake in the combined entity. While Glencore has an interest in the success of the combined mines, it must avoid making demands so excessive that the entire merger falls apart.
