Its all about the market pricing in RISK of either development or non-development of the shareprice and project.
When Hanlong was about with the takeover the market had a decent amount of confidence in the project being developed and rated at valuation at 40c-ish (around $1 billion mkt cap). Then Hanlong takeover fell over and the market priced/rated the asset for failure/non-development.
Any sniff that there is a financier (with credentials, not a unknown Chinese mob) for this project with credentials will see this be re-rated back to 30c+ going forward.
