The Rubaya mine in the eastern Democratic Republic of Congo is a bustling hub of activity, with over 10,000 miners extracting coltan, an essential component in mobile phones. Recently, M23 rebels permitted a BBC team to explore this vital mining site, revealing the harsh reality of life underground amid a complex backdrop of conflict and instability.

Miners work tirelessly in grueling conditions, digging deep into the earth to extract ore while navigating extreme heat and potential hazards. Yet, for many, such labor is a lifeline, providing much-needed income—enabling workers like Peter Osiasi to support their families and build better lives.

The mine is located in North Kivu province, where the region boasts 15% of the world's coltan supply, attracting interest from various factions over the years, including the military. Following a recent ceasefire between DR Congo and Rwanda, the M23 rebels maintain control, ensuring that daily operations proceed without armed conflict on site.

M23 has established a semblance of order, claiming to provide security and systems for conflict resolution among miners. However, the environment is fraught with allegations of exploitation, with reports suggesting the M23 profits significantly from taxing coltan resources.

While local miners expressed gratitude for improvements in safety and some level of peace, they also lamented their low wages. With foreign investments on the horizon, local leaders hope any funds will bring about better living conditions, infrastructure, and fairer pay for the miner community. Though uncertainty looms, miners like Osiasi call for sustained peace and better compensation as they strive for a brighter future.
