It normally means that another company is interested in a companies project, a intent to get involved by funding or joint venture, or a intent of a offer to buy a project.
Also can be a intent to be a board member or removal of the board or a board member.
A letter of intent can also be in regards to a legal issue over a lease or ownership.
I think that this could be good news for the company and its shareholders, more likely that someone is interested in the companies leases.
I do not hold, but my wife does due to me telling her about this company.
