US invests $2 billion in critical mineral and material supply chains

The US government has signed nearly $2 billion in deals looking to strengthen the US’s supply chain security for critical minerals and technologies. The capital takes multiple forms from equity loans to direct investments. The largest is a $1.4 billion conditional loan to Sila Nanotechnologies, a US-based silicon anode company. The company currently operates a facility in Moses Lake, Washington with plans for a second phase of production towards the end of the decade. This latest round of funding builds on the plethora of investments the US has made in the battery and critical mineral space over the course of Donald Trump’s second presidency such as investing in MP Materials’ rare earths project and Ivanhoe Electric’s Santa Cruz copper project. “While the Trump Administration continues to invest in critical minerals, know-how, and strategic technologies to build a mine-to-magnet supply chain, these recent investment announcements also reflect the US ambition to build a next-generation mine-to-battery supply chain to reduce its dependence on China,” said Bryan Bille, Benchmark’s policy and geopolitics principal.

Winter storm disruption at Argentina’s Hombre Muerto lithium brine site may mean changes to permitting regime

The worst winter storm in Argentina’s Puna region for years has cut land access to one of the country’s largest brine lithium salars, Hombre Muerto, from 19–27 July, where the road opened only for 4x4 vehicles. While the disruption in raw lithium tonnage is likely to be negligible, the situation is likely to encourage changes to permit conditions and greater requirements for operators to contribute to road maintenance. Satellite imagery shows up to two metres of snow on the roads into Hombre Muerto. Several Rio Tinto and Zijin employees and contractors were brought out after being stranded, four of them isolated for more than three days. Galan's camp, wellfield roads and evaporation ponds at Hombre Muerto West under a metre of snow. Rio Tinto suspended operations at both Fenix and Sal de Vida preventively.

Record low copper treatment charges supported by alternative smelter revenues

Copper smelter treatment charges (TCs), the charge levied by smelters to process copper concentrates, have hit record lows in recent weeks as a result of years of smelter overcapacity, particularly in China. As of 7th August, copper TCs were at -$173/tonne.  Concentrate supply has not grown quickly enough in recent years to make use of all the additional capacity among smelters, but strong byproduct prices, high premiums, and high copper prices have supported smelters despite dwindling TC proceeds.
