There were no 'poor-man's fields' in the North Island because almost no alluvial gold existed there. The first gold discovery was made by a Tasmanian, Charles Ring, near the future town of Coromandel in the North Island in 1852, but this field did not flourish.

Alluvial gold ore are mainly mined from land surface or river or underground. There are various types of gold raw material: alluvial gold, placer gold, sand gold, river gold, gold tailing, etc. The main gold beneficiation process includes feeding, washing, sieving, rough separation, final concentration and refining.

An alluvial fan is a triangle-shaped deposit of gravel, sand, and even smaller pieces of sediment, such as silt.This sediment is called alluvium. Alluvial fans are usually created as flowing water interacts with mountains, hills, or the steep walls of canyons. Streams carrying alluvium can be trickles of rainwater, a fast-moving creek, a powerful river, or even runoff from agriculture or industry.
