There are two things that could have major impacts on improving the viability of mining projects:
1. Planning, developing and operating projects with the end-use, full closure design in mind (building it to progressively enable closure shortly following the end of operations of a mine), and
2. Flipping evaluation of a potential development on its head - evaluate the worth of the entire property - with value placed on every component of the system - including the overburden and "waste" materials being excavated and moved in order to reach that desired, valued ore. This is monetizing the waste streams that every operation generates - at the front-end planning and assessment phase.
