ESG & Transparency

We don't claim to
be perfect. We claim
to be transparent.

Every metric published here is independently verified. The targets we've missed are listed alongside the ones we've hit.

Environment

Water: our biggest challenge

Tanzania is water-stressed. Mining uses water. We can't change that fundamental tension — but we account for every litre.

Process water recycled 83%

Target: 90% by 2026

30 litres per tonne of ore

Industry average: 60–80 litres. We've halved it. No freshwater extraction from rivers — only deep boreholes and rainwater harvesting.

Land

What we disturb, we restore

Underground block caving limits our surface footprint to 4.2 hectares — compared with 150+ for a comparable open pit.

12,000 native trees planted (2023) — survival rate 67%

Community

The trust account

$2.1M

2024 community payment

1.5% of revenue — not profit. The payment happens before we calculate shareholder returns.

Villages decide the projects

We don't choose where the money goes. The 11 surrounding villages elect a committee. In 2024 they chose: a secondary school science lab, three boreholes, and a mobile health clinic.

10% co-contribution

Every community project requires a 10% local contribution — labour or materials. It prevents dependency. It builds ownership. It was their idea, not ours.

Safety

Where we fail

Mining is dangerous. We do not pretend otherwise. What we commit to is learning from every incident.

Lost-time injuries (2024)

2

Both minor fractures. Down from 5 in 2023. Both led to immediate task redesign.

Near-miss reports (2024)

147

We reward near-miss reporting. A reported near-miss is a prevented injury.

One fatality (2016)

A haul truck driver died in a rollover. We changed slope design, installed roll-over protection on every vehicle. The driver's name is on the wall in our safety office.

The hard trade-offs

Cyanide

We use it. There is no viable alternative for our ore type. We destroy 99.97% before tailings leave the circuit. Published monthly.

Diesel

Haul trucks and generators burn diesel. We are trialling battery-electric loaders underground. But we're not pretending the transition is imminent — it's at least 5 years away at scale.

Expatriate specialists

40% of specialist roles are expatriates. We want that number to be zero. We have 14 Tanzanians in accelerated development programmes right now.
