President Hakainde Hichilema’s re-election provides greater policy continuity for Zambia’s mining sector, but the focus is now shifting from investment commitments and macroeconomic stabilisation toward whether the country can translate its expanding copper project pipeline into sustained production growth.​ Official results confirmed Hichilema’s second-term victory on August 18, with around 60% of the vote. For mining investors, the result reduces uncertainty around the policy direction that has underpinned Zambia’s recent push to attract capital into copper and other strategic minerals.​ Zambia is targeting annual copper production of 3 million tonnes by 2031, nearly triple current output levels. The strategy depends on a combination of brownfield expansions, new mine developments and continued exploration, making execution over the next several years critical to determining whether the target can be achieved.​ The main constraint is increasingly infrastructure rather than geological potential. Mining companies have highlighted electricity availability as one of the most important risks to future production growth, with industry estimates indicating that roughly 2,000 MW of additional power capacity will be required to support the planned expansion of the mining sector.​ Climate risk adds further complexity. Zambia’s heavy dependence on hydropower leaves the system exposed to weak rainfall and reservoir inflows, while the developing 2026–27 El Niño raises the possibility of renewed pressure on electricity supply. Reuters notes that previous drought-related shortages constrained mining activity and remain an important risk to the country’s copper-growth outlook.​ From a copper-market perspective, Hichilema’s second term therefore represents a transition from policy continuity to delivery. Zambia has attracted renewed mining investment and built a substantial project pipeline, but reaching the 3 million-tonne target will depend on whether new mines and expansions can be brought online alongside sufficient power, infrastructure and financing.​The next phase of Zambia’s copper story will therefore be measured less by announced investment and more by actual tonnes produced.

LME copper inventories increased for two consecutive trading sessions. On August 14, LME copper inventories increased by 2,850 mt to 207,800 mt, and on August 17, inventories further increased by 15,700 mt to 223,600 mt. The cumulative increase over the two trading sessions was 18,600 mt, representing a growth rate of about 9.1%. In particular, warehouse inflows reached 17,500 mt on August 17, driving a sharp rebound in inventories that day. In terms of warrant structure, as of August 17, LME copper registered warrants increased to 123,100 mt, up by 20,000 mt from August 14. Registered warrants increased significantly and the ratio of cancelled warrants declined; as inventories increased, intraday copper prices touched a low of around $14,000/mt.
