I doubt SHSH will use SFMI for smelting. Unless SFMI has or gets a permit to use added chemicals during smelting, I think they are leaving behind most of the silver in the slag, which they obviously will save for later processing. That's why SFMI's dore is 65% gold when there is probably much more silver than gold in the original ore. SHSH's Lakeview concentrates are mostly silver I think, so SFMI's smelter wouldn't help much.
