I’m posting this for people who are new like my good self with a lot to learn. This is alien to me but starting to understand from some very good posters on here who in the main aren’t derogatory to newbies like myself.
All three—Mineral Resource Estimates (MRE), Pre-Feasibility Studies (PFS), and Definitive Feasibility Studies (DFS)—can significantly push up share prices if they are positive, as they represent de-risking milestones and increasing value.
However, the magnitude of the push depends on the stage of the project:
MRE (Mineral Resource Estimate): Primarily drives share price jumps for junior explorers by revealing the potential scale of a deposit, often causing sharp increases upon positive results.
PFS (Pre-Feasibility Study): Acts as a major catalyst by outlining project economics, reducing risk, and demonstrating viability, which helps shift companies from explorers to developers.
DFS (Definitive Feasibility Study): Offers the highest certainty (bankable level). A positive DFS often results in the most significant, sustained share price appreciation because it confirms the project's viability to financiers.
Conclusion: A positive DFS is generally considered the most powerful catalyst for a sustained, material share price increase, as it signifies the final, "bankable" step before a development decision.
