Is Dragon's Fäboliden sustainable?

Dragon has apparently not published environmental permit applications of Fäboliden.

There is community discussion paper about environmental impact
on their pages.
This is document by a law firm trying to say that there would not be
substantial harm from 100 000 ton test mining.
However the document also indicates that there would be substantial levels
of heavy metals and arsene in waters from acid producing waste.
The plan for water purification at the end of 2015 was to filter it to ground.

This I would interpret as spoiling of land and ground water and even surface
waters. At least ground water spoling is prohibited in European Union directives.
I assume this must have been improved for any permi tapplication

possibly they are not very proud of this plan because it is not easy
to find from their web pages (in the site map)

In  dragon's operations there is tendency to overlook
environmental issues, which can be observed from
the disqualified EIA of Kuusamo:

which has lead to opposition of mining in Kuusamo:

and major permit problems in Orivesi

and Vammala enrichment plant

What is common with these:
The problems were not timely disclosed when the negative decission came,
but possibly taken up with next quaterly report, which has
given a possible benefit for traders reading Finnich news papers or following
environmental authorities.
