Ann: Andover Ni-Cu Project Drilling Update, page-20

don't panic.......CHN and BSX are both examples of stocks that retraced after their recent cp raises only to get it all back. Admittedly 50% is a bigger slide. SVY hasn't but that story is far from over
As far as your question to earlier is.....no. the mineralisation in an orebody can pinch and fold and be quite complex so don't expect economic mineralisation each and every hole. a lot of people made this mistake at Chalice on its early holes and cashed out and it has now gone up another 350%. and remember it took them over 100 holes before they hit the discovery hole at Nova.
