President Trump wants America to produce more of the much-needed mineral, but a 50 percent tariff could undermine his aim of a manufacturing renaissance.

President Donald Trump announced a 50% tariff on copper imports on Tueday, a move aimed at bolstering domestic production and reducing U.S. reliance on foreign supplies, particularly from Chile, which accounts for nearly 35% of U.S. copper imports.

Chilean copper mines had their best month of export revenue in more than three years in June, with the increase in value outstripping price gains in a sign of rising production.

This year, BMI estimates global copper mine output to rise 2.5% as production in Chile recovers and the giant Oyu Tolgoi mine in Mongolia ramps up. Those in Peru, Russia and Zambia will also remain among the major contributors, it adds.

U.S. President Donald Trump's 50% tariff on copper has placed a record premium on prices of the metal in the United States that is likely to ease over the coming months as a stockpile created by traders anticipating the levy works through the system.

Super Copper has agreed to acquire 100% ownership of the Castilla copper project, a 5,800-hectare exploration area in Chile's Atacama region, from Verdant Resources for $100,000 in an all-cash transaction.
