Well worth reading this article---Is what got me down the road to finding a ASX that was exploring for silver in Mexico---GRM is that micro cap---soon to be a jnr cap

-Mexico does have byproduct silver from some of its gold mines, but the majority is produced from primary silver mines. This country is blessed with several geological structures that contain numerous high-grade silver systems. And some of the world?s purest silver mines can be found within Mexico?s robust silver belts.
This geology supports Mexico?s modern-day silver rush, and this country?s fairly-accurate historical compass is guiding the way. The old mining-industry adage of ?the best place to find [silver] is where it is already known to exist? is all too true in Mexico?s case. And today?s geologists know full well that many of Mexico?s historic mining operations may have only scratched the surface of their silver deposits.
