Cassiterite is the ore that built Jos. Nigeria was one of the world's major tin producers for most of the twentieth century, and the Plateau still holds both primary pegmatite tin and enormous volumes of reworkable alluvial ground.

Tin Oxide (SnO2)
An Old Province, Worked Properly
Much of the Jos tin field has been mined, abandoned and mined again by hand. We approach it as a resource that rewards proper survey and gravity recovery rather than guesswork.
High Density Recovery
At a specific gravity near 7, cassiterite separates cleanly by gravity, which keeps recovery simple and chemical free.
Columbite Co-recovery
Jos cassiterite is routinely associated with columbite-tantalite. Both are recovered and sold separately.
Tailings Reassessment
Historic tailings across the Plateau often still carry payable tin. We survey before we assume ground is spent.
