Freeport – McMoRan Inc is developing new technology

ByVictoria

After 154 years of digging at Morenci, all the easily recoverable copper has been mined. Left behind are towering piles of waste rock that hold nearly 10 million tons of the metal seen as critical to global electrification. It’s a cache that could prove key to President Donald Trump’s ambition to boost US production of critical minerals.

Freeport-McMoRan Inc., which owns Morenci, is trying to develop technology that can burrow within those gigantic waste piles and extract low-grade copper that miners previously saw as too expensive and difficult to process.

“For a long time, we just didn’t think it was possible to recover any of this stuff,” said Robert Pollock, Morenci’s site manager, gazing up at a waste pile the size of a Manhattan office building. “But now, all this historical copper – we’re going after it.”

    A contested mine in Central Idaho that will produce gold and antimony earned the U.S. Forest Service’s final approval following a lengthy environmental review and objections from the Nez Perce Tribe, which will lose access for decades to federal lands guaranteed by a U.S. treaty.

    “This approval elevates the Stibnite Gold Project to an elite class of projects in America that have cleared NEPA,” Jon Cherry, Pepetua’s president and CEO, said in a statement.

    “The tribe’s treaties with the United States are the supreme law of the land and remain binding,”

    Northern Superior Resources Inc is pleased to announce that it has completed the acquisition of the Hazeur, Monster Lake East, and Monster Lake West Properties originally announced on June 16, 2025 (the “ Transaction “), expanding its total land position in the Chibougamau Gold Camp from 60,016 hectares to 68,522 hectares.

    The Company sees potential to expand the Philibert deposit along strike to the west, particularly within multiple shear zones such as the Red Fox Zone, which historically has seen the most drilling.

    “This acquisition is a major step forward in unlocking the broader potential of the Chibougamau Gold Camp. Not only do these new properties host known gold mineralization and compelling exploration upside, but they also extend key geological structures directly linked to the Philibert deposit. Combined with recent drilling success and a growing resource base, Philibert is rapidly emerging as a cornerstone asset in a camp now coming into prominence on the global stage,” said Simon Marcotte, President and Chief Executive Officer.

    Gold prices rose to a record high on Wednesday on safe-haven demand following U.S. President Donald Trump’s latest tariff threats, while investors awaited minutes of the Federal Reserve’s January policy meeting.

    Spot gold surged to an all-time high of $2,946.85/oz earlier in the session and was last down 0.2% at $2,928.88 as the dollar crept higher as of 12:17 pm ET (1714 GMT).

    “We are in a state of unusual-heightened uncertainty… the catalyst is the tariffs and trade talks or threats that are going on around the world,” which is supporting the prices, said Paul Wong, market strategist at Sprott Asset Management.

    Among other metals, spot silver, used in electrical components, shed 0.7% to $32.64 an ounce, which aims to challenge a 10-year high.

    Platinum declined 2.1% to $966.65 and palladium eased 1.9% to $968.43.
