Remote sensing, in the context of mineral deposit prospecting, refers to the use of technology to acquire data (usually images) about the Earth as seen from the air or within space. This data is used to create maps, which help to describe the Earth’s surface and its properties. Satellite and aircraft take snapshots of the Earth, from which data such as electro-magnetic radiation, heat and light reflected/emitted from the surface of the Earth, can be collected. Remote sensing is an attractive prospecting method for some minerals because:

• It does not require direct contact
• It is cost effective, allows companies to get an idea of the surface around them on a larger scale
• Displays the surface of the land as well as vegetation
• Helps to determine where sites and work may be planned, as well as determine the areas which are not as favorable to be worked on. Mining companies can use this to help determine where a mine can be placed based on an outcome of favorable conditions and properties.
