I see the production of a separate silver rich concentrate as an optimization worth a few percent, so yes, astute enough but not something that should have much impact on the feasibility study outcomes. It should be possible to produce a DFS based on a single concentrate that would still indicate what the mine is worth. The postponement of the DFS looks like it is about timing its issue to be in a more positive market and investment environment, so it would be easier to raise the funding for the mine. There is some risk that it could be worse, if the bear market lingers beyond then.

As @WLJ indicated, the El Pilar assays results have become even more important and, for me, are a decision point as to what to do next with my investment in AAU. I don't think I would ever sell all of it, as there will come a time when La Demajagua will shine even if El Pilar doesn't, but another rebalancing might be on the cards. I'm praying (figuratively) that El Pilar assays will be great.
