  • Camimex (Cámara Minera de México) informed that during the first half of 2021 the mining industry generated 40,895 new direct jobs and more than 2 million new indirect jobs, boasting salaries 36% higher than the national average.  Also, during 2020 the industry invested US$3,532 M (US$3.5 billion, in American notation) and is posed to invest further US$5,034 M (US$5 billion in American notation) in 2021 and a total of more than US$24,000 M (US$24 billion in American notation) in the next six years.  
  • Mexico was the top producer of silver in the world in 2020, with 5,541 tonnes, China and Peru stand in the second and third place producing 3,443 tonnes and 2,991 tonnes respectively.
  • There are 1,190 mining projects funded by foreign capital in Mexico, but 6 of each 10 are idle, regardless of the increase in metal prices. Of the 1,190 projects, 754 are idle, 307 in exploration, 78 in production, 43 in development and 8 have closed. One of the issues affecting the mining industry in Mexico is the fiscal load, with taxes on profit of 52.7%, same tax burden that in other countries is lower: USA 30.2%, Canada 34.6%, Chile 35.7%, Peru 39.9%.
