Scene 1 — The Foundation

"If you ask anyone what drives Tanzania's growth, you'll usually get two answers: the roads and buildings we construct above ground, and the rich minerals we extract from beneath it.

For a long time, people treated construction and mining as two entirely different worlds. But when I looked at them, I saw something different. I saw two industries built on the exact same fundamental principle: taking raw, unpolished earth and turning it into lasting value."

Scene 2 — The Vision & The Name

"That realization is why I founded Yellow Stone Traders & General Supplies.

People often ask me about the name, 'Yellow Stone.' To us, gold is Tanzania's most precious stone. It represents our identity, our wealth, and above all, our standard. We took that standard and built a company designed to serve both worlds under one accountable roof.

On one hand, we're in the field — designing blueprints, drafting technical plans, and constructing the roads, classrooms, and clinics that hold our communities together. On the other hand, we're deep in the mining sector — supplying heavy excavation equipment, sourcing essential ore-processing chemicals, and helping operators extract every single grain of value from every tonne of stone."

Scene 3 — The Uncompromising Standard

"We operate by a very simple rule: we treat every road, classroom, and clinic we build with the exact same care we bring to a gram of gold. Nothing leaves our hands unfinished.

Whether we're working under our Primary Mining Licence out in the Kigosi goldfields of Bukombe District, or laying the foundation for a school in a local neighborhood, the commitment doesn't change. We don't believe in shortcuts, and we don't pass the buck to third-party contractors."

Scene 4 — How We Work & The Future

"Our process is simple because it has to be: understand the site, draft it properly, source what the job needs, build to specification, and stand behind the result — from the initial blueprint all the way to breaking ground and handover.

Whether you are looking to build lasting public infrastructure, launch a private development, or optimize your mineral processing yields, Yellow Stone was built to be your partner every step of the way. Two industries. One standard. Let's build together."

Our Story

## Founded on Two Trades That Built Tanzania

Ask anyone what drives Tanzania's growth and you'll usually get two answers: the roads and buildings raised above ground, and the rich minerals drawn from beneath it. For a long time, most people treated construction and mining as two entirely separate worlds — different sites, different crews, different rulebooks. But Matemla Michael Lameck looked at them and saw something else: two industries built on the exact same fundamental principle — taking raw, unpolished earth and turning it into lasting value. That single realization is why he founded Yellow Stone Traders & General Supplies.

People often ask about the name. To us, gold is Tanzania's most precious stone — it represents our identity, our wealth, and above all, our standard. We took that standard and built a company designed to serve both worlds under one accountable roof. On one hand, we're in the field: designing blueprints, drafting technical plans, and constructing the roads, classrooms and clinics that hold our communities together. On the other, we're deep in the mining sector: supplying heavy excavation equipment, sourcing essential ore-processing chemicals, and helping operators extract every grain of value from every tonne of stone.

That standard doesn't bend depending on the job. Whether the crew is working under our Primary Mining Licence out in the Kigosi goldfields of Bukombe District, or laying the foundation for a school in a local neighborhood, the commitment stays the same. We don't believe in shortcuts, and we don't pass the buck to third-party contractors — the people who draft the plan are accountable for the build that follows it, and the people who supply the equipment stand behind how it performs on site.

The process is kept deliberately simple, because it has to be: understand the site and the brief, draft it properly, source what the job needs, build or supply to specification, and stand behind the result — from the initial blueprint all the way through to breaking ground and handover. Whether the goal is lasting public infrastructure, a private development, or better mineral-processing yields, Yellow Stone was built to be a partner every step of the way. Two industries. One standard.
