Ann: Aircore Drill Assays Received at Rockford Project, page-12

Trading halt was based on ASX sending them a speeding ticket asking why had the priced increased over the last week of trading with a noticeable increase in volume traded. Read https://hotcopper.com.au/threads/ann-response-to-asx-price-query.3109976/#post-21296903
it explains everything in pretty much plain english as to why the halt was required!
As anyone who knows this company and what it is doing these results were expected this side of Xmas. Traders/Speculators have simply gotten into this stock hoping for a quick profit on the back of some positive news coming from the drill results. Anyone with a background in exploration would understand that the results that would have been reported wouldn't have been that high as the minerals that make up the Ni, Cu weren't visible in large enough quantities, gold is a little harder to define and visualise (unless you have nuggets or veining along bands - mainly obtained when diamond drilling) so getting assay results is the best way forward.
