RE:Malcolm's Nuclear/Uranium laundry list...I believe we can be surprised by just how fast a mine development can proceed. From NXE's presentation, in the first half of 2016, metallurgical, geotechnical and hydrogeological testing was begun. In the second half of 2016, continued envronmental and other test work in preparation for permit applications. For 2017, ongoing test work for economic future studies, with an economic study completed by the end of 2017 as the basis for permit application. See page 18 here:
