Background on Glencore and its Relevance

Glencore, a London-listed mining company, is considering closing its Horne smelter, Canada’s largest copper metal producer. This decision stems from environmental concerns and the substantial funds required to modernize the facilities, according to two sources familiar with the matter.

Glencore’s Copper Metal Production in Canada

While Glencore does not disclose the production figures of its Canadian copper metal operations, industry sources estimate that they exceed 300,000 tonnes annually.

Impact on Global Copper Supply

The closure of Horne would exacerbate global supply shortages, partly due to disruptions like accidents at Indonesian and Chilean mines.

Anticipated deficits in the coming years have driven up copper prices, reaching a record high of $11,200 per tonne on October 29.

Glencore’s Official Statement

“We are not currently evaluating the closure of the Horne or CCR smelters,” said a Glencore spokesperson in response to a Reuters request for comment.

Canadian Copper Operations

Glencore’s Canadian copper operations include the Horne and Canadian Copper Refinery (CCR) facilities, both located in Quebec province. These centers employ over 1,000 workers, according to industry sources.

“Smelters worldwide are currently facing significant pressures, including substantial financial, regulatory, and operational challenges,” the Glencore spokesperson stated. “Horne and CCR are not exempt from these pressures, but both play a crucial role in supplying critical raw materials for the North American and foreign markets.”

Future of Horne and CCR

Although both plants are set to close, no specific date has been determined, according to the two sources. Operations reportedly require potentially over $200 million for modernization.
