Sword of Damocles: The legal storm that threatens to level gold mine that built empires
A landmark legal case could, if successful, effectively force the mine to shutter.

On her graduation day from Tarime Teachers’ College in 2009, Lucy Ryoba walked across the stage with a diploma in her hand and a knot of dread in her stomach.
She was one of thousands of newly minted graduates about to trade their gowns for an unforgiving struggle for survival. The uncertainty of her future was not just a worry; it was palpable.
Today, the mother of three laughs at the memory.
Those graduation-day doubts were so overwhelming that she never dreamed she would become the CEO of LUMRY Company Limited, a thriving enterprise supplying one of Africa’s largest gold mines.
“Three things built my success,” she says, seated in a modern office surrounded by order forms and equipment samples. “Being born in Tarime, sheer hard work, and the grace of Almighty God.”
Three things built my success, being born in Tarime, sheer hard work, and the grace of Almighty God,” Lucy Ryoba, CEO of LUMRY Company Limited based in Tarime, Tanzania.
But that same blessing—being born in the shadow of Barrick’s North Mara Gold Mine—is now under existential threat.
A landmark legal case brought by British law firm Leigh Day against the London Bullion Market Association (LBMA) could, if successful, effectively force the mine to shutter.
For Lucy, her 30 employees, and the millions of Tanzanians who depend on the mine’s ecosystem, the verdict could be catastrophic.
The road from kiosk to c-suite
Lucy’s journey began in a tiny kiosk selling mobile money services and household sundries.
Living at Nyangoto Village, she watched as the North Mara mine transformed the dusty landscape into a corridor of commerce.
“I realised there were opportunities at the mine,” she recalls.
When she heard about entrepreneurship training programmes for local residents, she jumped at the chance.
The curriculum was rigorous, teaching her how to tender for contracts, manage supply chains, and meet the exacting standards of a multinational corporation.
Her first break was modest: Catering for mine security. But it was the foot in the door she needed.
In 2016, she registered LUMRY Company Limited. Today, her firm supplies personal protective equipment (PPE), stationery and office supplies, industrial consumables, and event decoration services (LUMRY Decorations).
“Everything I have,” she says softly, “came from the ripple effects of that mine.”
The Leigh Day Case: A sword of Damocles
The legal battle brewing in London threatens to sever those ripples at their source.
Leigh Day alleges that the LBMA’s certification of North Mara gold is flawed, citing historical claims of human rights abuses, environmental damage, and extrajudicial killings.
If the court rules against the LBMA, North Mara gold could be delisted as non-compliant.
This would effectively bar the mine’s output from the international bullion market, rendering the operation financially unviable.
Everything I have came from the ripple effects of that mine,” Lucy Ryoba, CEO of LUMRY Company Limited based in Tarime, Tanzania.
While Barrick Mining vigorously denies the allegations—pointing to improved grievance mechanisms and community partnerships—the local population sees a different danger.
“If the mine stops operations, it’s not a legal case anymore,” warns Lucy, explaining: “It’s a funeral.”
The domino effect on host communities
Nyangoto is one of several villages receiving a 1-per cent royalty from production.
This revenue has been the architect of local development, funding paved health clinics and maternal health programmes, new primary and secondary school wings, and boreholes for clean water access.
The economic impact extends far beyond the pits.
A 2022 study suggests that for every direct mining job, five indirect jobs are created in transport, retail, and construction.
If North Mara closes, those jobs—and the school fees they pay for—evaporate.
National economic repercussions
Gold is a pillar of Tanzania’s economy, accounting for roughly 30 per cent to 40 per cent of non-traditional exports.
North Mara alone produces approximately 250,000 ounces annually.
The Tanzanian government holds a 16 per cent free carried interest in the mine through Twiga Minerals – a joint venture with Barrick Mining.
This stake delivers millions in dividends used for national infrastructure and educationΩ
