The rescission of the coal policy means that Category 2 lands are now available for coal leasing, and only that - leasing.
There are a great number of coal leases in this province that have been in effect for decades, that have seen absolutely no development activity on them at all. Coal rights leasing is different in AB from O&G in that regard, in that in O&G, you have to undertake certain activities (e.g., drilling) to continue to hold licenses/leases. With coal, as long as you pay your annual rental fees, you can sit on a coal lease indefinitely.
Should this company wish to actually advance this development, they still have to go through the Alberta Environment approval process, and, for a mine of this size, now the new Federal Impact Assessment Act (yes, the infamous "Bill C-69" that has ruffled so many Alberta feathers on other fronts of late). Thus, likely a joint review panel process. The first step in this review process is stakeholder consultation to define the terms of reference for the impact assessment.
To my mind, the angling/outdoors community is much more likely to have a meaningful say/effect by providing input into that review process, when/if the time comes, rather than try to get the current government to do anything with respect to this coal policy rescission.
This looks like an Australian penny stock mining company, whose value trades on news with respect to their "projects" - that sword cuts both ways, i.e., negative news (e.g., tough going on environmental approvals, due to credible stakeholder opposition) has a way of causing these sorts of things to go away...
