China Owns Canada's Only Antimony Mine And Shuttered It In Critical Minerals Power Play

Core Insights - The Beaver Brook mine in Newfoundland, potentially the largest antimony producer in North America, is currently dormant and owned by China, raising concerns about national security and supply chain dependencies for critical minerals [1][3][6] Industry Overview - Antimony is essential for military hardware, with its price skyrocketing from approximately US$5,900 per tonne to over US$50,000 following China's export controls [3][4] - China dominates the global antimony supply, producing about 48% of the world's mined antimony and controlling the majority of refined output [28] Geopolitical Implications - The closure of Beaver Brook by China is seen as a strategic move to limit global supply and hinder Western military capabilities, particularly for the U.S. [8][41] - The Canadian government's response to China's control over critical mineral assets, including Beaver Brook, has been criticized as inadequate, especially in light of rising geopolitical tensions [14][41] Strategic Importance of Beaver Brook - At full production, Beaver Brook could supply about 5% of the world's antimony, making it a significant asset for North American defense supply chains [9][10] - The mine's current status raises questions about Canada's sovereignty and its ability to reclaim control over strategic resources [41][41] Market Dynamics - The U.S. is actively seeking to secure non-China-dependent supply chains for critical minerals, with significant investments in domestic projects like Perpetua Resources in Idaho [10][34] - The potential for China to manipulate antimony prices by controlling Beaver Brook adds complexity to the market dynamics and investment strategies in the sector [36][37]
