Luminex Provides Tarqui Update and Drill Results

Drilling Highlights:

• TARQ4D – 0.32% copper equivalent over 218 metres from surface
• TARQ10D – 0.18% copper equivalent over 72 metres from 72 metres down hole

VANCOUVER, BC, July 11, 2022 /PRNewswire/ - Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the "Company" or "Luminex") would like to provide an update on its Tarqui project, where BHP Group Limited ("BHP") has completed its Phase 2 drill program that commenced in late 2021, pursuant to a July 2019 earn-in and joint venture agreement. BHP completed the current drill program in June 2022 and has received assays from seven of ten holes. Drilling at the project has now totaled 6,862 metres, over thirteen drill holes between the Phase 1 and Phase 2 programs.

BHP has formally notified Luminex that it will not be continuing with the earn-in at Tarqui and will begin the process of transitioning the operatorship back to Luminex, with expected completion in Q4 2022. Luminex will review all of the project data and work completed to date and evaluate next steps for the Tarqui project.

Prior to drilling, BHP conducted surface geological mapping and rock chip and soil sampling comprised of 1,015 samples and 2,815 samples respectively. Additionally, the company contracted Geotech to conduct a helicopter borne survey with a VTEM (Versatile Time Domain Electromagnetic) system comprising 349 line kilometres over the property.

Drilling targeted two large (>2 square kilometre) copper-molybdenum anomalies (illustrated in Figure 1) with coincident conductive and magnetic response. At these two target areas, mineralization is related to diorite and granodiorite porphyry stocks hosted within the Jurassic Zamora batholith, which in turn intrudes Cretaceous Sedimentary rocks. At both, mineralization is associated with potassic alteration and outboard propylitic alteration that is overprinted by intermediate sulphidation zinc-lead-silver veins. Drilling within the two copper soil anomalies consistently intersected reportable copper-molybdenum intervals, that are provided in Table 1, with drill hole locations illustrated in Figure 1.

Note: Intervals in the reported holes are calculated using a cut-off of 0.10% Cu with maximum internal dilution of eight continuous metres. Sampling is done in consistent, continuous 2-metre intervals. Equivalent values were calculated using copper equivalent values were calculated using the following prices: a gold price of US$1,600 per ounce, a copper price of US$3.00 per pound, a molybdenum price of US$8.00 per pound and a silver price of US$20.00 per ounce. No allowances have been made for recovery losses that may occur should mining eventually result.
