XRF SpectrometerOne of the tec tools that JPES used in the Mexican exploration was a hand held XRF Specrrum Anayliser. This dis[pays the elements in the rock (core) sample and I believe the %.When he said "Indications could not be better"..this was not based on wishful thhinking but hard data.So the tech team on site have a good idea what the core contains. The XRF gives spot analysis and you still need lab assays to see the big picture. If I am wrong I hope JPRES will correct my comments.GLTA CP
