Mining is an intensive activity. It involves roads, infrastructure, large machinery, and makes a scar on the landscape. If this mine is approved, future Canadians are going to benefit from the zircon oxides present in this deposit as well. Leaving them as tailings is a waste because it will require all of these same disruptions to the environment again when it is deemed strategically necessary or at least commercially acceptable. Canada does no mining for Zirconia.  Ytterbium oxide doped zirconium oxide is a ceramic with many existing and potential future applications. We should produce it in Canada if we are mining the rocks that contain it anyway.
