My view of the Grupo situation is simple.
1. Clearly the MDP deposit crosses the Western border
2. Grupo will never mine it, it is too small for them, but big for AZS
3. So, Grupo might as well negotiate with AZS a percentage of net smelter royalties on their portion of the deposit (such as they already have with the existing AZS bit) rather than have nothing. A small percentage of something is worth more than 100% of nothing.
4. There will be an agreement
