Mid-sized copper mine — +113% NPV by changing the question
Traditional study locked in 7 Mtpa / 190 t trucks / no technology. blueprint asked again, holistically.

CHALLENGE
Linear study pre-selected a 7 Mtpa plant with a 190 t haul fleet before alternatives were tested. Value left on the table; risk inadequately quantified.

WHAT BLUEPRINT DID
Re-built the value chain in blueprint. Scenario-driven across rate, cut-off grade and process flow. Layered automation, preconcentration, electrification and mine-to-mill — all TRL 7+.

OUTCOME
113% NPV uplift
+113% NPV uplift vs the traditional base case. New design at 10 Mtpa with 100 t trucks, smaller fleet, smarter blast.
