Here are how prices looked at the close of trading:

BHP has found what it claims is a potential new copper mineralized system near its existing Olympic Dam mine in Australia, the company said.

Shares in Aurubis, Europe’s largest copper smelter, dropped after the company acknowledged it has shut three of four copper smelters for unplanned maintenance.
The refined tin market, worth around $7.5 billion per year, could benefit from the electric vehicle boom, leading industry specialists who attended the 7th annual International Tin Association (ITA) investor day in London said.

Global miner Anglo American is optimistic about its copper production in Chile for the coming years, the company said, also raising or tightening upward its output guidance figures through 2020.

A lack of sufficient alumina supply has caused European aluminium producer Trimet to cut alumina input at its plants in Germany and France by 10%, the company told Fastmarkets.

Steelmakers in Colombia earlier this month requested that their government conduct a safeguarding investigation into imports of rebar from all origins.

Copper’s long-term outlook is constrained by the industry’s limited ability to bring new supply online fast enough to meet rising demand, with permitting delays, higher capital costs and policy risks slowing project development, industry executives said at the FT Commodities Global Summit on Wednesday April 22.
Capital is flowing back into junior mining, but selectively. Investment is increasingly favouring development‑stage assets with clearer paths to production, supported by government funding and strategic partnerships. While demand for critical minerals underpins the cycle, early‑stage explorers continue to struggle for capital as investors prioritise discipline, ESG alignment and near‑term cash flow.
Copper in concentrate production from Ivanhoe Mines' Kamoa-Kakula complex in the Democratic Republic of Congo (DRC) fell to 61,906 tonnes in the first quarter, down by 54% from 133,120 tonnes a year earlier, with the company now evaluating local third-party concentrate purchases to advance the ramp-up of its on-site smelter, according to an April 13 production release as the market focused its attention on the impact of global sulfuric acid shortages during CESCO Week in Chile from April 13-17.
China's planned sulfuric acid export ban from May 1, historic lows for copper concentrates treatment and refining charges (TC/RCs) and a fragmenting 2026 benchmark system dominated CESCO Week 2026 in Santiago from April 13-17.
The proposal would align the index more closely with physically traded volumes in the region, and enable it to adjust to evolving market conditions. This proposal follows an observed widening of the spread between trader and smelter purchase components of the index and is aligned with a majority of market feedback. Additionally, Fastmarkets seeks feedback […]
Until now, aluminium has been hard to move, not hard to find. Global aluminium supply had remained technically intact, even as output was curtailed in parts of the Gulf, inventory buffers were drawn down or repositioned, and shipping through the Strait of Hormuz was severely disrupted.
