Strategic Minerals
Cassiterite (Tin Ore) — Sourcing and Buyer Requirements
Cassiterite is the primary ore of tin and occurs widely in the pegmatite and alluvial systems of the Democratic Republic of Congo and the wider Central African belt.
Overview
Cassiterite at a glance
Tin demand is driven principally by solder in electronics, alongside chemicals, tinplate and alloys. Buyers assess cassiterite on contained tin, deleterious elements and the completeness of the origin record.
Afrimet Global Resources handles cassiterite enquiries on the same basis as its other strategic minerals: counterparty verification first, written specification second, independent assay third, contract last.
Cassiterite frequently occurs alongside lithium-bearing pegmatites, including in the Manono corridor, and is assessed separately where it is present.

Questions
Frequently asked questions
How is cassiterite valued?
On contained tin established by independent assay, with penalty elements and deductions agreed in writing before contract.
Is cassiterite related to your lithium interest?
Cassiterite commonly occurs with the pegmatite systems associated with hard-rock lithium, including in the Manono corridor. Each is assessed on its own evidence.
What is the minimum parcel size?
Parcel size is discussed per enquiry against logistics and compliance requirements.
