Satellite imagery is a very useful exploration tool, particularly in Chile where extensive areas of land are vegetation poor or free (such as the Atacama). By manipulating the visible spectra you can highlight particular rock types (based on their reflectance characteristics - though this will only tell you that they are different from their neighbours, not what the rock actually is in terms of a definitive classification). What it does particularly well is to pick out alteration zones within and around rock outcrops. This is often related to hydrothermal activity that MAY have an economic component, so as a 'first pass' tool it can highlight particular areas that warrant further investigation on the ground.

What it cannot do is 'see ore' (unless you have a Kiruna-style deposit sitting on the surface) and it certainly can't give you tonnage and grade, so those thinking you can use it to define a 'World Class' deposit as a stand-alone tool should go and sit in the corner with a pointy hat on...
