Overview
In April 2004 PhotoSat signed an agreement with the Servicio Geológico Mexicano – SGM to distribute its data.
Under this agreement, copies of the SGM technical data is available in Vancouver from PhotoSat, for ready distribution to Canadian mining exploration companies looking to evaluate and acquire mineral exploration properties in Mexico.
Ownership of the data remains the exclusive property of SGM. The data is to be distributed by PhotoSat under standard SGM data licence terms.
