In New South Wales lode tin occurs principally in the granite and stream tin under the basaltic country in the extreme north of the state, at Tenterfield, Emmaville, Tingha, and in other districts of New England.
As stream tin it occurs abundantly in some of the alluvial deposits derived from the crystalline area, especially on the west coast.
All tin, except a small quantity produced by the shaft furnace process from exceptionally pure stream tin ore, requires refining by liquation and "boiling" before it is ready for the market.
It occurs in lodes and as stream-tin, and is worked by Chinese in large numbers who inhabit villages of their own.
