PUR's "Julimar Discovery" in Calingiri East?, page-901

I came across an article on * from a couple of years ago regarding why nearology plays mostly don't work out. The link to the article as follows:

As a shareholder of PUR, with high hopes that it will replicate the success of Chalice, this made me pretty uneasy.

Surely all these positive aerial and ground loop electromagnetic surveys are strong indicators of mineralisation. It's difficult to comprehend that they could all just be false signals. I have not done much research on the events leading to Chalice's discovery and was wondering if they just got lucky with one of their strikes or were all their EM surveys substantiated with positive drill results. Can anyone with knowledge of Chalice's history of exploration shed some light on this?
