Mexico's Mining Law gives ultimate right to the host Nation, not to a bunch of ex Bre-Ex crooks. No silver besides the stuff you hold in your hand is owned by you. Remember that!!
Mineral exploration and mining in Mexico are regulated by the Mining Law of 1992 (as amended in 2005), which establishes that all minerals found in Mexican territory are owned by the Mexican nation, and that private parties may exploit such minerals (except oil and nuclear fuel minerals) through mining licenses, or concessions, granted by the Federal Government.
