We will soon be offering Satellite Images & Remote Sensing services.


Satellite remote sensing images have been widely and successfully used for mineral exploration
since the launch of Landsat in 1972. This application relies mostly on the capability of the sensor
to register spectral signatures and other geological features related to mineral deposits. Gold is
one of the most important mineral commodities that have been searched with the use of satellite
remote sensing images over the last 30 years.

Although gold cannot be “seen” directly by any remote sensor, the presence of minerals which
form in association with this precious metal can be detected based on their spectral signatures. A
group of minerals which occur in the alteration zones associated with gold deposits, generically
referred as “clay minerals,” have diagnostic spectral signatures mostly in the shortwave infrared
portion of the electromagnetic spectrum. These signatures can be used to locate sites most
favorable to the occurrence of deposits, saving the mineral industry a great deal of time and costs
in their exploration programs.

An example of this is work being done by E. A. Guinness of Washington University in St. Louis. He has been studying Landsat photos of southern Missouri and has found that the canopy of oak and hickory growing over granite areas look brighter in the infrared than it does when the trees are growing in softer, sedimentary rock areas.

Historic Gold Maps of Victoria And New South Wales


These maps and documents have been scanned at various resolutions, and can be downloded.

These maps can provide valuable insights into new areas.

We are geo-referencing the maps  where possible. If you would like a certain map done, please email propack@goldmaps.com.au
