On the surface (and underground, LOL), this doesn't seem like a significant news release.
Wrong. This is realy good news.
As a former environmental consultant, I can say that not having the environmental permits in place can shut a business down (at least in Ontario), as well as court, lawyers (aka money) fines, and possibly jail for the principals.
It means that the Company is doing things right, and the right way.
Now the Company no longer has this permit to worry about, and they can get on with the business of exploring, extracting and milling our mountain of silver and gold.
