• Siguiri mine produced 165,000 ounces in H1 2025

• Output rose 28% year-on-year; Q1 alone saw +67%

• Production surge driven by higher ore throughput and plant optimization

The Siguiri mine in Guinea is one of the six African assets in AngloGold Ashanti's gold portfolio. It stood out in Q1 2025 with gold production up 67%, driven by an increase in the quantity of ore processed.

In the first half of 2025, AngloGold Ashanti achieved attributable production of 165,000 ounces of gold from its 85%-owned Siguiri mine in Guinea. This figure from its operational report published on Friday August 1 represents a 28% increase on the 128,000 ounces produced over the same period in 2024.

This performance shows a sustained improvement in production over the two quarters. Following a 67% increase from January to March 2025, Siguiri's production remained solid from April to June, up 6% year-on-year (85,000 ounces vs. 80,000 ounces in 2024). Including the 15% held by the Guinean state, the mine delivered a total of 194,000 ounces of gold during the half-year under review.

This operational momentum was driven by several key factors. First and foremost is the increase in the quantity of ore processed over the period, first by 20% in the first quarter, then by 7% in the second quarter. AngloGold also highlights “optimized plant utilization […], as well as a 3% improvement in recovery rates.”

Thanks to the contribution from Siguiri as well as strong operating results from other African mines such as Obuasi and Geita, AngloGold's overall production stood at 1.27 million ounces of gold in the first half, up by around 2% year-on-year. The group, which operates other gold mines in Australia and South America, is targeting annual production of between 2.9 and 3.2 million ounces by 2025.
