A state that has been hiding in the shadows may turn out to be what Mexico needs to raise its levels of gold production. But the state has experienced bumps on the road as security issues scared away operators in the past and halted projects such as Campo Morado, previously owned by Nyrstar and acquired by Telson Resources. Sonora holds the number one position in Mexico’s gold production but Guerrero is slowly starting to catch up to Sonora as in 2016 it produced 15,215kg of gold, a 70 percent rise from the 8,972kg in 2015. Between 2017 and 2020, CAMIMEX predicts that companies will invest over US$2.5 billion in the state's gold projects.
