The supply of antimony is increasingly becoming a strategic issue for North America and Europe. All the more striking is the fact that Beaver Brook, Canada’s only primary antimony mine, remains idle. The mine in Newfoundland and Labrador, located approximately 45 kilometers southwest of Glenwood, is owned by Chinese state-owned enterprise China Minmetals and is currently not in production. In an environment of rising demand for strategic metals, this raises new questions about supply security, geopolitical vulnerability, and the influence of foreign-controlled supply chains.
This debate is particularly charged when it comes to antimony. The metal is used in flame retardants, lead-acid batteries, and semiconductors, but also plays a role in a range of military applications, including ammunition, infrared sensors, and night vision technology. This makes antimony a raw material at the intersection of industry, defense, and security policy. Against this backdrop, the fact that Canada’s only primary project in this area has been on care and maintenance for some time appears symbolic of a larger structural problem.
Beaver Brook Reveals the Strategic Gap in Antimony
The history of Beaver Brook illustrates how closely commodity markets and geopolitical interests are now intertwined. The mine first began producing antimony concentrate in 2012, but ceased operations the following year due to weak market conditions. In 2019, operations were briefly reactivated before shutting down again in 2023. Since then, Beaver Brook has remained in maintenance mode, even though the importance of antimony for Western industrial and security interests has increased significantly – as has the antimony price.
At full capacity, the project has considerable potential. According to available data, the facility could produce approximately 6,000 tonnes of antimony concentrate per year. According to analysts, this would represent about 5% of global supply. For a market characterized by few players and increasingly under geopolitical scrutiny, this would be a significant volume.
The fact that Beaver Brook remains idle precisely at a time when the USA, Canada, and Europe are discussing the establishment of secure and diversified supply chains for critical minerals adds additional urgency to the case. With antimony, it is no longer just about industrial supply, but also about how resilient Western supply chains actually are in a more conflict-prone global environment.
China’s Influence on Antimony Shapes the Market
The strategic importance of Beaver Brook is directly linked to China’s dominance in the antimony market. China controls the majority of global mining, refining, and processing capacity. This gives the country not only large production volumes, but also decisive leverage along the entire value chain. When Beijing began restricting exports of the mineral in 2024, global antimony prices rose significantly. At the same time, it became clear how heavily the market relies on a single source.
Against this backdrop, it is significant that Beaver Brook has been under Chinese control for 15 years. The mine was originally acquired by Hunan Nonferrous Metals in 2009 for $29.5 million. Since then, the project has been under the control of China Minmetals. While Canada has already responded to national security concerns in other areas of its resource sector and in 2022 ordered Chinese companies to withdraw from several lithium exploration firms, the ownership structure at Beaver Brook has remained unchanged.
This very circumstance is attracting attention in political and industry circles. Investigative research and statements from the mining industry have raised the question of what role the idle mine could play in a strained commodity market. This is less about established facts than about the strategic influence such an asset can exert.
Antimony Also Becomes a Politically Sensitive Raw Material
The debate gains additional edge through statements from the Canadian mining community. Anthony Vaccaro, President of The Northern Miner, referred in 2025 to discussions in mining and political circles suggesting speculation about possible strategic intentions by Beijing regarding Beaver Brook. At its core is the consideration that an owner in a strained market could theoretically ramp up production again to bring additional volumes to market and thereby influence price movements. The text provides no concrete evidence of such action, but the mere existence of such speculation shows how sensitive the antimony issue has become.
This presents Western governments with a multi-layered problem. On one hand, they want to create more resilient supply chains for critical minerals. On the other hand, they are operating in a market where ownership structures, capital flows, and geopolitical interests are closely intertwined. The Beaver Brook case is thus exemplary of the difficulties in building supply security without simultaneously intensifying existing international dependencies.
North America Seeks Alternatives in the Antimony Market
While Canada currently has no active antimony production of its own, the USA and its allies are attempting to build new structures. Demand for antimony is likely to continue growing with rising expenditures on defense, electronics, and energy infrastructure. Accordingly, funding has already been directed in the USA to projects and companies that could supply antimony and other strategic metals.
For this very reason, Beaver Brook could regain importance in the future. However, as long as the mine remains on care and maintenance, Canada lacks its own active source of antimony. This increases dependence on foreign-controlled supply chains in a market that is becoming increasingly relevant for both industry and defense. Beaver Brook is thus not just an idle mining project, but a visible indication of how large the gap in strategic raw materials in the West still is.
One company that could help reduce this gap, at least partially, is Canadian Rua Gold (WKN A40QYC / TSX RUA). The company primarily searches for gold on its mining projects in New Zealand, but has deposits that are naturally endowed with antimony as well. In our view, investors who want to benefit from the Western pursuit of greater independence from China should examine companies like these. More on this exciting story:
