Just found AR3s metallurgical program, looks like they can extract on average 44% whilst HRE can extract 78.5%. HRE uses 3.8Kg/T of acid, AR3 does not list how much they used whilst testing. I also should've mentioned that AR3 raised $11.1 million @ $0.45c and as of 28/07/23 they have $15.1 million in the bank whilst HRE has $2.1 million from their latest quarterly announcements.
