Aljustrel Mine StreamI have spoken with the company about this directly, back when the Lundin deal was announced. When SST makes a deal, they own the silver in the ground. It does not matter who buys the project, the buyer has to honor the agreement with SST. SST effectively has "title" to the silver in the project.
Other wise any mine operator could sell a stream, and then go out and resell the entire project with the silver included and leave an SST or SLW with nothing. This would be ridiculous. SST owns a portion of the project, the silver portion. They are like a JV partner who does not have operating control of the project.
Best of success to all.
