Financiers around the world have expressed interest in the 500-hectare organic salmon farm to be located off Inis Oirr in the Aran Islands, though BIM said it was not at liberty to disclose who they are.
As previously reported on Afloat.ie, the proposed fish farm would be the largest of its kind in Europe, set to double the State's production of organic salmon.
BIM says it is already receiving inquiries for jobs from emigrants wishing to return home.
IFI recently issued a statement regarding its submission on the project's Environmental Impact Statement, raising concerns about the scale of the development and the impact of sea lice - infestations of which are often concentrated by aquaculture.
The public consultation that began in mid-October is scheduled to conclude next Wednesday 12 December.
