Cascas Discovery Highlights:

Copper Anomaly

• Expansion of the soil copper anomaly to over 7 kms in length, remaining open in multiple directions.
• Discovery of high-grade porphyry copper mineralization in outcrop in northern sector (up to 1.1% Cu).

New Gold Target (Kuru)

• Discovery of large geochemical gold footprint – largest soil anomaly 3 kms long and remains open.
• Discovery of outcropping epithermal vein system grading up to 8.80 g/t gold in rock and soils.
• Interpreted to be peripheral epithermal gold to Shakai porphyry copper-molybdenum target.

Vancouver, British Columbia – Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the "Company" or "Luminex") is pleased to provide an update on the development of exploration activities at the Shakai porphyry copper discovery as well as an exciting gold discovery. New high-grade copper sample results will assist the Company with specific drill hole targeting in the southern Shakai area. Also, the Company has discovered an epithermal gold-silver vein system located approximately 2 kilometres to the southwest of Shakai (see Figure 1). The new gold-silver zone is named Kuru and both zones are located at the Company's 100% owned Cascas copper-gold project in southern Ecuador. Exploration continues at Kuru while drill targeting advances at Shakai. Luminex plans to commence a 3,000-metre initial drill program this quarter.

Marshall Koval, CEO and Director commented: "The significant strike length expansion of the copper anomaly and the discovery of the Kuru gold zone at Cascas demonstrate the increasing potential of the project. The size of the anomalous copper footprint is impressive and may suggest two or more coalescing porphyry copper-molybdenum deposits are present. In addition, our team sees potential for a copper enrichment zone at the target. Luminex has mobilized the majority of our geologists to Cascas to prepare for drilling."

At Shakai, new grid soil sampling results have expanded the copper in soil anomaly to more than 7 kilometres long, extending it principally to the north-northwest (Figure 2). The anomaly remains open to the northwest and also under Cretaceous limestone cover rocks to the east. Geochemically, the Shakai area is defined by coincident anomalous soil copper and molybdenum anomalies with high copper/zinc ratios – all indicative of the central part of a porphyry copper-molybdenum system. Geophysically, Shakai's coincident airborne magnetic high with a ZTEM feature in the southern part may also indicate the magnetite-bearing, resistive potassic core of such a deposit. Areas of low magnetic response adjacent to such areas may be mapping later overprinting phyllic alteration, which converts magnetite to pyrite.

Recent sampling at Shakai has returned higher grade copper results and samples were frequently noted to contain covellite and chalcocite with rare native copper in addition to ubiquitous chalcopyrite and bornite, highlighting the potential for porphyry copper enrichment at Shakai (Figure 4).

At the new Kuru zone, gold and silver occurs in granodiorite-hosted quartz-carbonate-pyrite veins and stockworks with clay alteration that are interpreted to be low sulphidation epithermal in character. Contoured soil sample results delineate three anomalous zones that are shown in Figure 4. The largest measures 3 kilometres by 300 metres, is oriented north-northwest and is open to the south. Rock chip samples from veins within this anomaly have returned assays up to 8.8 g/t gold and 3.6 g/t silver. A second irregular anomaly measures approximately 1.3 kilometres by 900 metres and rock chip samples from veins within this anomaly have returned assays up to 3.17 g/t gold and 20.9 g/t silver. A third north-northwest-, south-southeast-trending anomaly measures approximately 900 by 300 metres. No rock chip samples have so far been collected from within this soil anomaly. Luminex will continue exploring Kuru to identify drill targets.
