Given no news from Cardinal - My guess is as follows:
Broadview jumped the gun on their web site.
There likley is an non binding letter of intent. (thus no need to press release) They would likely have to get three years audited financial statements on this asset to issue shares for it. This takes time.
They would need TSX approval. This requires audited statements see above.
They would need board of director approval and formal P&S agreement.
Execpt something between end of June and end of July if due dillegence passes.
If due dillegence fails, then Cardinal would never have to press release it.
My thoughts
