2 Until 2015, 25 mil 315 mining concessions were granted, covering 248,306 km2; 12.74% of the total surface of the Mexican Republic SGM is promoting, for public bidding, 71 projects over a surface of 4,652 km2, that is, 0.23% of the total territory
Only in 13% of the country have been granted mining concessions to particulars and enterprises. 3 México, main producer of 16 minerals

The 1:50,000 mapping is performed preferably in those areas that geologically offer the best chances to contain mineral deposits
This activity provides invaluable information to the investors, so it is expected to be a reliable source to take decisions and so, save time and economical resources. 7 Scale: 1:2’000,000 Edition: 2007

It took 16 years to complete the aeromagnetic coverage of the country –included the territorial sea–, using its own infrastructure and knowledge.

Levels of information • Lithology • Structural arrange • Sampling • Metallic and non metallic mineral deposits • Cross sections • Stratigraphy • Abstract and final report 11 Geological, geochemistry and geophysical interpretation are used to identify new prospective areas aimed for detailed exploration. Most of the actual mines started as a single prospect. More than 700 localities were suggested between 2007 and 2015. From those, more than 80 became a government exploration target and, eventually, an allotment. 104°40' 104°20'
