Those properties have been explored alreadyWangoTardo: Know this: MXR is exploring properties that have already been explored. Why do you think those other companies decided not to mine those properties?
Could it be that those properies have some good assay results that impresses amateurs like you but not enough for a profitable mining operation? I have seen this scenario a hundred times and they all end the same and it's not pretty.
Did you read DrStoxxman's blog about MXR?
