PB/MG have covered the following characteristics . . . investors can formulate decisions on what is known:
"Cassiterite (SnO2) is the principal ore of tin, and forms the basis of one of the global commodity chains for electronic consumer goods. Cassiterite is translucent when pure, but brown or black when impurities are present. It is found either in primary or alluvial (placer) deposits. Primary deposits are formed by deep-seated geological processes, such as the intrusion of granite in which the cassiterite is embedded in hard rocks, such as pegmatite or quartz. Alluvial deposits are formed by the mechanical concentration of heavy cassiterite in riverbeds, in which the tin ore is contained in gravel and sand. Since cassiterite is resistant
to weathering, it also often concentrates in alluvial deposits derived from cassiterite-bearing rocks. Tin is obtained by reducing the ore using bituminous coal in a reverberatory furnace".
