REGCHEM is a
geochemical database containing stream sediment geochemical analyses compiled
from open file mining company exploration reports. The database contains data on
over 21 000 samples that have each been analysed for several elements such as
gold, silver, arsenic, copper, lead and, zinc.

REGCHEM is supported by GEOEXPL -
a custom written computer software application which operates under Microsoft
Access. The data can be plotted as maps using a geographic information system
(GIS) package called MapInfo, which can incorporate data from other data sets
such as mineral deposit sites from the geological resource map database,
GERM.
