According to Ground News on September 17, 2026, Berenberg Bank upgraded Antofagasta shares to a Buy rating and set a price target of 4,400 pence, sharpening the positive analyst narrative around the London-listed copper miner.

Data cited by financial portals for September 16, 2026 indicate that Antofagasta shares traded in a range between roughly 3,582.00 and 3,647.00 pence on the London Stock Exchange, leaving the close of 3,594.00 pence still around 20 percent below a 52-week high of 4,475.00 pence and comfortably above a 52-week low near 2,254.00 pence.

Sector tailwind supports Antofagasta stock

As RTTNews reported on September 16, 2026, UK mining shares including Antofagasta posted strong gains as European equities advanced and commodity-related sectors performed well, adding a broader market tailwind to the company-specific analyst upgrade.

Intraday commentary from London market wrap-ups cited by financial portals for September 16, 2026 noted that Antofagasta was up about 3.7 percent at midday before settling to a closing gain of 2.7 percent, underlining that investors used the sector strength and analyst support to add exposure to the copper producer.

Stock valuation and investor perspective

The latest closing level of 3,594.00 pence on September 16, 2026 places Antofagasta stock meaningfully below Berenberg Bank’s new 4,400 pence price target, implying potential upside of more than 20 percent from the most recent close if the analyst scenario were to be realized.

For investors, the combination of a recent 2.7 percent price gain, a 52-week high of 4,475.00 pence that still lies well above the current level, and a fresh Buy rating with a target of 4,400 pence creates a focused narrative: Antofagasta shares are benefiting from renewed confidence in mining stocks while remaining below both their recent peak and the newly stated analyst target.
