Endako has a daily production of 26,500 t/d of 0.06% Mo and supports its own smelter. Sisson Brook's planned daily mining rate is comparable but the Mo grade is about half that of Endako (Sisson has W as a coproduct) so Sisson, by comparison, would need to double it's Mo grade or daily tonnage to support a Mo smelter (roaster) comparable to that of Endako's.

The new East flank zone could be the sweet spot for Mo and could increase the overall Mo grade substantially. Drill results for this zone should be released in the near future.

I also noticed that Endako was advertising only a 7 year mine life left at 0.04% Mo cutoff grade. Reducing the cutoff to 0.03% Mo last month will prolong the life of this mine.
