Copper Mineralisation Extends Beyond Current Resource at Zambia’s Mumbezhi Project

Published: Aug 12, 2026 18:30

According to foreign media reports, step-out drilling at the Nyungu Central deposit within Zambia’s Mumbezhi Copper Project has returned further copper intersections, extending a newly identified mineralised zone southeast beyond the boundaries of the current Mineral Resource Estimate (MRE).​

Recent drilling returned 65.8 m grading 0.42% copper from 226 m, including higher-grade intervals of 17.0 m at 0.58% copper and 13.2 m at 0.82% copper. A separate intersection returned 29.6 m grading 0.34% copper from 237 m, including 5.2 m at 0.80% copper. The results extend the known copper system outside the current resource estimate and provide additional targets for continued exploration.​

A total of 16 Phase 3 diamond drill holes covering 4,723 m have so far been completed at the southern end of Nyungu Central, while priority assay results remain pending for seven holes. In addition, a 6,200 m infill diamond drilling programme commenced at Nyungu Central in late July, supported by an additional drill rig now on site.​

Exploration is also continuing across the wider Mumbezhi Project, with four diamond drill rigs currently operating. Three are focused on Nyungu Central, while another is drilling at the regional Sharamba prospect, where exploration is targeting shallow copper mineralisation associated with a strong airborne electromagnetic anomaly. Visual copper mineralisation has been observed in five holes drilled along approximately 700 m of strike on the western side of the anomaly.​

The latest intersections further extend the known copper mineralisation beyond the existing Nyungu Central resource boundaries, while several priority assay results remain outstanding. Continued step-out and infill drilling will provide further indications of the scale and continuity of the mineralised system and its potential to support future resource expansion at Mumbezhi.

Doosan Invests $701.5M to Expand CCL Production in Korea and China Through 2028
Doosan Group said on September 17 that it will invest approximately KRW 968.4 billion (about USD 701.5 million) to expand high-end copper-clad laminate (CCL) production in South Korea and China. Roughly KRW 421 billion will expand domestic CCL lines for optical modules, while about KRW 547.4 billion will build a new plant in Changshu, China, for AI accelerators and network switches via wholly-owned Doosan Electro-Materials Changshu, with an additional KRW 182.4 billion capital injection. The three-year investment runs through 2028, with new lines scheduled to begin operations in the second half of 2028. In H1 2026, utilization at Doosan's Jeungpyeong and Gimcheon plants reached 109.8% and 102.7%, respectively, while the China plant ran at 92.2%. Q2 2026 optical-module CCL sales jumped more than tenfold year-on-year to about KRW 50 billion, and network-board CCL sales reached KRW 369.2 billion, accounting for more than half of the Electronics Business Group's revenue.
