RB.CN — LONG The author argues the real gains in mining come from early re-rating rather than production, and that small Canadian explorers like Rumble Resources trade at low valuations because uncertainty is high, which is the entire opportunity. The mechanism is asymmetric upside from re-rating, with the discipline being to size explorers smaller than blue chips. The stated risk is high uncertainty and the mistake of sizing them like blue chips.
Companies like Rumble Resources trade at low valuations because uncertainty is high. That uncertainty is the entire opportunity.
