I don't know what heavy equipment you would be working on at the SIRG mine since as far as I know the only piece of heavy equipment that SIRG owns is a fork lift that will be used to load the copper cathodes.

All the dig/haul operations are contracted with Desert Construction of Kingman, perhaps you should have applied there. They will be using their own equipment so they would have their own mechanics.
