presto72,

I think your "did" should have been a "didn't" and will answer accordingly:
I assume BOA management were probably told that a section of sulphides appeared in a drill core and they may have thought that the onsite crew could leak info to others - hence the trading halt to protect all shareholders.
It depends on how you read the release. To me it was perfectly normal and I am happy to wait and see the next release when assay results are disclosed.
The drill site was not in the main street of Kalgoorlie - it was some out in the scrub some 100kms east of Norseman. Probably hard to find a spare magnet or XRF.
