The cause of this situation is that investors rather put money into stocks that are in good positions of financial return (PLS), or those that have been given money for its R&D (NVX), or those that are inherently undervalued (insert your pick here). This is especially true when ECT's seemingly not doing much for the past year, and other stocks have made advancement after advancement. Hence, they are selling off their holdings of ECT for those more attractive picks.

The only saving grace of ECT might remain to be government investments from Federal Budget to be released tonight, and Dan Andrew's upcoming election. However, with all this hype with green renewable energy and lithium, I don't know what kind of government incentive may be suited for what ECT is aiming to achieve with lignite. This is especially unlikely when the Greens are involved, which seems to hate coal more than anything.
