For those that cant see The Australian article, it suggests that while some big Australian companies like BHP, Rio and South 32 may have initially declined Chalice's partnership offers, leaving it to other battery metals companies to progress, the greatly reduced share price may tempt them back in. Or, as the article suggests, the low price may enthuse them to buy in/take over at low prices instead of forming a partnership. So Blackrock could be acting as an agent in this. Although presumably that article is behind today's price drop as the retail market worries about the implications of not finding a partner, and noone is stepping in to snap up the shares on offer, so who knows?
