For decades, the flow-through share has been as Canadian as the bush plane — a tax incentive that helped funnel money into junior explorers scratching at the Precambrian Shield from Red Lake to the Ring of Fire. But not everyone sees it as a lifeline. Crescat Capital, one of the most influential hedge funds in the junior mining space, is calling the system a “blight” — and when a major player talks, the industry listens, whether it wants to or not.

Crescat’s argument cuts to something real: that flow-through structures can distort capital allocation, propping up exploration spending that isn’t driven by genuine geological conviction but by tax efficiency. For communities across Northern Ontario that depend on junior companies to do the early, risky work of finding the next major deposit, this debate is anything but abstract. If the flow-through model is funneling money into the wrong projects, then the right projects — the ones that could anchor the next generation of northern mines — may be getting crowded out or overlooked.

This isn’t the first time someone has questioned the sacred cows of Canadian mining finance, and it won’t be the last. But with Ottawa’s critical minerals strategy leaning hard on junior exploration to deliver the deposits that could power the energy transition, the timing of this critique matters. The flow-through share debate is really a debate about what kind of mining future Canada — and Northern Ontario in particular — is building toward. Click here to read the full story.
