Gerteisen has provided an explanation for the large reduction in ounces and grade at RPM North.
No diagrams were provided in the recent ann, and the explanation now is based on a bit of handwaving. It seems to me that the initial inferred resource included a large extension that was not supported by any drills. Then it was found not to exist.
In my experience inferred resource estimates have usually held up well with further drilling. This is a definite outlier, and reduces my confidence in inferred resources.
