Namibia’s mining sector slowed in September 2025, with the Mining Production Composite Index — which tracks Diamonds, Zinc Concentrate & Contained, Gold Bullion and Uranium — falling by 4.1% compared to August.
This follows a sharper decline of 9.4% recorded in August 2025.
Year-on-year, the index slipped by 0.3%, pointing to muted performance across key minerals.
The latest data shows uneven output across the sector, with precious metals and base minerals weakening while uranium continued to provide support.
The Namibia Statistics Agency (NSA) said the month-on-month contraction was driven mainly by reduced production of Diamonds, Zinc Concentrate & Contained, and Gold Bullion, although Uranium output increased during the period.
“The decline in the composite index is mainly driven by lower output from our diamond and base metal sectors, although uranium remains resilient,” the NSA reported.
Diamond production dropped by 8.0% in September, following a steeper fall of 21.6% in August. On an annual basis, diamond output fell by 1.7%.
Zinc Concentrate & Contained production declined by 7.7% month-on-month after a 1.8% decrease in August, and recorded a sharp annual fall of 33.4%.
Gold Bullion output fell by 6.1% in September, reversing the 5.8% growth recorded in August. Compared to September 2024, production was down 12.2%.
Uranium production increased by 6.2% month-on-month, following a 10.5% rise in August, and grew by 22.0% year-on-year.
The mixed performance comes as the mining industry continues to face fluctuating global demand and domestic production challenges, with uranium emerging as a key source of stability.
