Antofagasta plc (ISIN GB0000456144, London: ANTO) saw its shares advance as mining stocks rallied alongside firmer metal prices and a stronger FTSE 100 on September 16, 2026. As Morningstar reported in its London market close wrap, mining names including Antofagasta gained around 2.7% as metal prices climbed and broader UK equities rallied. Intraday commentary from Interactive Investor noted that Antofagasta was up about 3.7% at midday as miners rallied ahead of a key Federal Reserve decision, underlining the sector tailwind during the session.
Data from market portals for September 16, 2026 indicate that Antofagasta shares closed at 3,594.00 pence with a previous close of 3,501.00 pence, implying a daily gain of roughly 2.7% on the London Stock Exchange.

Today’s drivers and events
Today, September 17, 2026, attention around Antofagasta is shaped mainly by macro and sector factors rather than a scheduled company-specific event. As Proactive Investors highlighted in its coverage of the September 16, 2026 London session, miners such as Antofagasta moved higher as investors positioned ahead of a Federal Reserve decision, linking the shares to global interest rate expectations and commodity price trends. That backdrop continues to frame sentiment today as markets look for signals on future US monetary policy and implications for growth-sensitive assets like copper producers.
Earnings calendars and recent company updates in the available period around September 17, 2026 do not indicate a confirmed Antofagasta quarterly or annual results release within the next few trading days, so trading today is likely to remain guided by sector news, macro data and moves in metal prices rather than a specific corporate event. Broader UK market developments, including any fresh moves in the FTSE 100 and in peer mining stocks, are therefore key reference points for Antofagasta as investors head into the open.
