Verification Statement

TECHNOLOGY TYPE: X-ray Fluorescence (XRF) Analyzer
APPLICATION: MEASUREMENT OF TRACE ELEMENTS IN SOIL AND SEDIMENT
TECHNOLOGY NAME: XLt 700 Series XRF Analyzer


Relative Accuracy: High
Median RPD : 0% - 10% (RPD - relative percent difference)
Target Elements Copper and Selenium


what ever readings you get, its going to be no more that 10% out from the actual from what i understand in the reading of Cu

Its always best to have samples and cores properly assayed and to use them as a means of giving out results..


but sbr is indicating in the last report exactly what your pointing out..


Spot sampling using a handheld XRF has confirmed elevated copper, lead and zinc values in these rocks


i still see the release as extremely positive and imho its saying as much as it should before getting the readings on the mineralisation and making it public
