There is a very simple way to verify SRGE's mining concessions. I have done it already and so have many others here. Call Tatiana and ask her. It's that simple. I don't believe all that " she is unreachable, she doesn't answer the phone, she won't give out any info" crap because I have spoken with her so I know it's possible and I know she will give out information.
It's a very simple process and nothing you can say will change the fact that it's been done many times already.
