HI there,
It would not say that it is a game changer - the new report points to indicated reserves of 795,900 an ~11% increase over the previous indicated reserves of 717,400. At the same time inferred resources dropped from 798,000 to 656,200, an ~18% decrease.
Since the report was announced before the bell, had it been material the stock price would have likely moved accordingly. Instead, it moved by a couple of percentage points. A good sign in a red day, but don't think it materially changes the investment thesis here.
