I would think that it is quite proper to refer to SIRG as a mining company. It's "certainley" not a dairy farm or grocery store. Even you called it a mine. If you can do it I don't see why it's so bad for all of us to call it a mine.
Please note that this is a mine that this company has never mined anything out of, so again, please provide proof that sirg ever mined anything. Of course if no proof can be provided that sirg has ever done any mining then the claim that they are a mining company will be nothing more than a bogus claim.
