More than 190 former employees of Lumwana Mining Company Limited have initiated a significant lawsuit against the company, seeking a staggering K2 billion in compensation. The plaintiffs allege severe negligence on the part of the mining giant, claiming they were exposed to uranium through contaminated drinking water provided at their workplace over an extended period.

The lawsuit, filed in the Lusaka High Court by Abraham Kamanga and 192 other former workers, details that these individuals were employed by Lumwana at various times between 2006 and April 17, 2025. The core of their claim revolves around water sourced from the Chimiwungo Crossing Dam, which they consumed while at work from 2012 onwards. They contend that this water contained uranium levels significantly exceeding permissible limits, posing a grave health risk.

The alleged contamination only came to light for the plaintiffs on November 8, 2023, following the mistaken circulation of an internal memo during an Incoming Pre-Shift meeting. Subsequent independent test results, dated November 16, 2023, reportedly corroborated these fears, revealing uranium concentrations up to six times higher than the maximum allowable limit of 0.03 milligrams per litre.

The consequences of this alleged exposure have been severe for the former employees. They claim to have suffered from long-term health complications, with several individuals diagnosed with various ailments. Tragically, one individual is reported to have died from complications directly linked to uranium exposure. Furthermore, 41 employees were medically discharged, 51 resigned, and four opted for voluntary separation. The psychological toll was also significant, with 69 workers undergoing trauma counselling after learning of the contamination.

Represented by their legal counsel, MSK Advocates, the plaintiffs are seeking a declaration from the court that Lumwana Mining Company Limited was negligent in its duties. They are demanding K10 million in compensation for each plaintiff, culminating in a total of K1.93 billion. Additionally, the lawsuit requests special damages to be assessed by the court, along with interest on the claimed amounts. This legal challenge emerges amidst other corporate developments for Lumwana, which has also revealed plans to significantly expand its copper production, aiming to double output and create thousands of jobs by 2028.
