RE:RE:RE:RE:Earl ResourcesLol!. I don't think that DME and RR are that nefarious. In reverse takeovers, companies with a product to sell will buy a Shell company listed on an exchange and then do an IPS to raise funds.
I think Earl was doing just that BUT this isn't a reverse takeover. Maybe RR knows the guys at Earl and they pitched the idea. Why leave a good, structurally viable, hole in the ground when the US could use it to store Hydrogen and other important gases.
Sounds like a solid plan. There is a company in NE Canada that found a large salt cave and they are planning to mine the salt (big demand for ancient salt, WHY?, anyone, anyone...No MICROPLASTICS i.e Why Himalayan pink salt is very popular) and use the caverns for energy storage.
Hydrogen (naturally occuring in mines) in big demand because of the space race.
