I disagree. The news release clearly states that the NSR belongs to a related company of Webb. He could have held out and prevented the project from going forward. I don't know of any person or company reducing royalty payments for a company that he was released from.
He is invested in the project, but reading this section of the news release speaks for itself: "We wish to thank Dr. Webb for his two decades of service to the Company, during which he laid the foundation for our transition from being an explorer to building the next gold mine in the NWT."
