Imagine a big flat steel plate 1" thick positioned horizontally.

 

Apply a small blowtorch to the bottom of one spot on the plate.

 

Keep doing this at different spots.

 

Eventually even the spots without blowtorch contact begin to heat up.

 

Watch for blowtorches being applied to the plate in the region of SE Arizona.

 

Hay Mountain could begin to heat up even without direct contact.

 

I grew up in the oil business. One day there would be little active interest in a region, and the next, after an unexpectedly successful wildcat well, every motel room would be taken by oil scouts, landsmen,  geologists, aspiring investors, etc. A cold region was made hot by a single discovery. This happens in mining too. It may happen in SE Arizona, possibly in Santa Cruz, Pima, and Cochise counties.

 

Other countries seem to be encouraging this by making it ever more costly and risky to invest in mines subject to kleptocratic seizure and hostage taking.
