I can answer some of those for you Chainsaw as you are so interested in the company.
rehabilitation costs - not sure but against $150 million of contained gold not an issue.
there is no town water and power to the site. Water not required as it will be dry crushing and sorting. Power will be diesel generator. The previous mining contractor will basically move back in.
environmental impact study - not sure when complete, but are probably working on it now but is dependent on sorter trials I would imaging.
