Ann: Positive Metallurgical Results Further Defines Flowsheet, page-15

With Gold systems it doesn't matter how much gold is in the ground if you cannot easily recover it.
-There are a number of Gold systems out there that only get 80% recovery rates, and need massive amounts of processing (and thus cost or dangerous chemicals) to extract any more than that.

So this announcement is saying that they can recover 95% and 92% of the gold using either a Float or Leach system.
Both of these systems are cheap and simple.

Meaning that it will Increase the amount of physical gold recoverable, and Decrease the cost to do so.

so definitely a positive result, because it significantly increases the likelihood of NVA switching from an Explorer to a Producer!!
