Vancouver, British Columbia – Luminex Resources Corp. (TSXV: LR) (US OTC: LUMIF) (the “Company” or “Luminex”) received notice from First Quantum Minerals Ltd. (“First Quantum”) that First Quantum will be terminating its earn-in option on the Company’s Orquideas copper-molybdenum focused concession in Ecuador.

First Quantum also is currently reviewing progress and exploration data on, and whether to continue with, its earn-in option on the Company’s Cascas concessions.
