The Rubaya area, nestled in the Masisi Hills of North Kivu province, has been under the careful watch of M23 rebels since April of last year, granting limited media access to showcase the intense labor involved in extracting coltan ore, crucial for mobile technology. The mine employs a staggering 10,000 individuals daily, most of whom work tirelessly, digging, transporting, and processing ore despite perilous conditions marked by high temperatures and hazardous gases.

"My life has really changed. Mining has really helped me," shared miner Peter Osiasi, illustrating the complicated relationship between hardship and opportunity in the mines. The Rubaya site, which holds around 15% of the world’s coltan supply, remains a target for investors worldwide, drawn by the wealth generated by this precious resource.

Recently, a ceasefire agreement between the Democratic Republic of Congo (DRC) and Rwanda hinted at the possibility of lasting peace, yet the underlying tensions persist. Armed groups, including the M23 — a group largely comprised of ethnic Tutsis — continue to command significant territory, raising questions about the region's governance and the safety of miners operating under the rebels’ jurisdiction.

Patrice Musafiri, the mine supervisor, emphasized the establishment of a secure and structured environment for mining activities. Despite the rebels' claims of improved conditions, miners have voiced their concerns about low wages and the need for sustainable investments that directly benefit local communities. "Any foreign investor can come here … as long as they come with development for our people," Musafiri stated, calling for initiatives to uplift the local population.

Global attention is turning toward the DRC's vast mineral resources, with potential U.S. investments looming. However, questions remain about the stability of operations given the ongoing influence of the M23. While some miners cautiously welcome the prospects of foreign aid and investment, they simultaneously plead for an end to hostilities that have dislocated thousands and brought untold suffering.

As the world’s demand for coltan continues unabated, the stories of those working in mines like Rubaya provide a stark reminder of the human cost of technological advancement. In the face of hardship, miners like Osiasi appeal to their leaders for peace and improved working conditions, wishing for brighter prospects in their often-unforgiving world. "I also appeal to the owners of the mines to increase our pay because it's very little," he expressed, mirroring a common hope among his peers.
