I'm not well versed in the law / precedents required - so this is just a guess of what would happen in this instance. But one would assume that there would have always been a majority shareholder, prior to works/drillings commencing (this would be, I imagine, part of the Due-diligence process).
However, if somehow in the unlikely event the majority shareholder got diluted to or sold off its interest to less than 50% and there was no individual stakeholder that had mroe than 50% - I would presume that there an entity would need to acquire interest to 'take over' the project.
This is, obviously, bound by the shareholders agreement of the Company and often it would have a first-right of refusal - as is the case for AVZ.
