$5,000 is very little, for a publicly reporting company- they have transfer agent fees as one example, don't know their office expenses but their must be expenses related to the mill even during the winter.Heck I don't know exactly how they operate , but I do know if they are trying to comply with permit conditions and projecting production in the fall, it is difficult to believe $5,000 is all the expenses for a quarter. Press releases cost money, 8k filings incur a cost. Quarterly 10q alone will cost more than $5,000.
Yes the sources you mention might provide a convertible credit line of some sort, but as a public company they would need to file an 8k on any such arrangement.
