Ann: Pre-Feasibility Study Presentation, page-12

Might be why many sold out - the realisation we still have a long way to go:

LCK now plans to advance the LCEP by production of a Bankable Feasibility Study that will define and progress the critical path activities including funding, urea production technology selection, and site activity preparation.LCK will commence the downstream Stage Bankable Feasibility Study in early 2021, and, in parallel, progress the upstream field development plan. The Company will also be conducting 3D seismic acquisition to determine the most prospective coal seams in which to drill further ISG wells. The Company anticipates having all the data required for an EIS submission for operation in the second half of 2021. Upon the completion of the seam identification process, the Company intends to drill up to five additional gasification wells that will supply a 5MW power station.
