Mexico's new Mining REFORM law is actually in place now...oh, this might hinder GSVR:
Similarly, the Mining Reform may potentially impact contractual relationships entered into by investors and / or mining companies prior to its enactment, potentially triggering claims for breach of contract, early termination, force majeure events, change in law and / or material adverse effect provisions. Involved parties should review whether any contractual changes or notices are necessary, required or convenient to preserve their interests as applicable in each case.
