About the NSR Considering the current lack of investor interest in the gold sector, this NSR of 1% / $5,000,000 is a good choice. The amount is not very high, they will have to invest it wisely, but Roscan will not have to wait for market conditions to improve to continue the work. To obtain an equivalent amount by issuing shares at 20 cents, Roscan would have diluted the shareholders by ~6%. In short, an NSR of 1% is a better solution. If the POG and the market for gold explorers recovers in 1 year, Roscan will always have the opportunity to finance itself otherwise, depending on the context.
Finally, we can understand that Osisko necessarily studied the file carefully before concluding this agreement. We can therefore assume that Osisko is confident that it will eventually be able to recover its investment, as well as a capital gain. It is therefore a sign of confidence in the potential of this project.
Regarding the SP, the market capitalization is still high, considering the level of progress of the project. Therefore, be careful because there is still a lot of money to invest before this project is really interesting for a potential buyer.
Also, remember that an NSR is not free money. If it does not dilute the shareholders on the spot, it still dilutes the income at the time of operation, or the value added during the sale of the project, depending on the agreement.
Good luck
