It’s a legacy of the backdoor listing/reverse takeover. Big Un limited was already listed and previously called something else and owned the (worthless) mine assets. So that BRTV could get a listing, the listed company changed its name to Big Un limited and acquired BRTV. It still owns the mine assets.

It’s a fairly common transaction, not the most worrying issue for shareholders.
