RE:SPROTT Funds ES did not directly invest in SPMT. It was one of his funds. There is an important distinction. And it's likely the interest in the company is wildcat proximity to NFG. A long shot. His fund invested not only in NFG, but many of the surrounding plays as well. ES is invested in some of the proximate NFG plays himself, but not SPMT.
I have shares in NFG. It's a great gold explorer.
