So using your own figures the reclamation of devastated tar sands regions is still only about 4% of what has been mined. Given the fact that is all that has been done in several decades of mining I will stand by my previously post that it is going to be a very long time if ever before the region is returned to its original state. In fact I am guessing that just leaving the area to nature would be almost as fast.
The figures I provided were for one company only - Suncor. There are approx. 48 companies working a multitude of extraction and mining projects in the Athabasca sands. Here's a list of the main companies in case you are interested:

It is also important to realize that many of the projects are active, they're obviously not going to begin reclamation before work has been completed.
You would likely be able to figure this out if you weren't so intent on disingenuously supporting the false-narrative that nothing is being done. Unfortunately, you apparently have no intention of educating yourself, only repeating anti-oil sands dogma. With that in mind, I could care less what you stand by. You likely still think there is a million and a half hectares of land and boreal forest ripped to pieces, I suppose you still stand by that little gem as well.
I can't help you with your self delusion. It's your choice...bask in ignorance, or put forth a bit of effort to understand what is actually going on.
