For those that like to do their homework and want to take a deeper dive into understanding the potential of what we are doing. I invite you to do some searching on Google for the exploration history of MAG Silvers' Juanicipio mine in Fresnillo.
Additionally, look for papers written by Arizona geologist Peter Megaw. He has focused most of his distinguished exploration career in Mexico. Much of it in Zacatecas state, and has written several scientific papers on the area. Including calling the region a perfect storm for big mines.
