Luminex Continues to Expand Cuyes West High-Grade Underground Mineralization; 7.0 Metres of 12.2 g/t Au Eq

• CU22-06 – 7.0 metres of 12.18 g/t Au Eq
• CU22-09 – 3.0 metres of 11.80 g/t Au Eq
• CU22-12– 50 metre down dip step-out below CU22-05 (5.0 metres of 30.47 g/t Au Eq): 7.0 metre interval with visually similar characteristics

VANCOUVER, BC, Dec. 5, 2022 /PRNewswire/ - Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the "Company" or "Luminex") is pleased to announce drill results from four holes at the Cuyes West structure and from three holes at the Ruiz structure. At Cuyes West, the current drilling has confirmed the strike length of the structure is in excess of 300 metres, and it has been mapped at surface for more than 500 metres. The drill intersection in hole CU22-12, the deepest so far, indicates that it has a vertical extent of at least 250 metres. The western edge of the Cuyes West structure is approximately 300 metres from the Camp deposit.

Marshall Koval, CEO and Director commented: "We are extremely pleased with the results coming in from our step-out drilling at Cuyes West. The mineralized structure is taking shape after the positive results from the first nine holes. The six additional pending holes, including the visual core logging on hole CU22-12 has the geological team optimistic about future success at Cuyes West. Outside of Cuyes West, we also have five holes pending at Camp. The team has planned a 2023 drill program to continue expanding Cuyes West and Camp. Given that the 2021 PEA did not include the Cuyes West discovery, the team looks forward to seeing its impact."

Hole CU22-06 intersected 7.0 metres from 225 metres down hole grading 11.88 g/t gold and 25.4 g/t silver (12.18 g/t Au Eq). This hole stepped out approximately 60 metres below hole CU22-01, which intersected 8.6 metres grading 5.10 g/t gold and 24.85 g/t silver (5.39 g/t Au Eq) within a wider interval of 17.6 metres grading 2.91 g/t gold and 15.23 g/t silver (3.09 g/t Au Eq). Combined with hole CU22-01, these holes may indicate the emergence of a high-grade vertical zone or "shoot".

Hole CU22-09 stepped out approximately 60 metres to depth on hole CU22-04 and intersected 12 metres grading 3.71 g/t gold, 21.2 g/t silver (3.97 g/t Au Eq.), including an intercept of 3.0 metres grading 11.51 g/t gold, 23.7 g/t silver (11.80 g/t Au Eq). Hole CU22-04 contained 4.0 metres grading 6.38 g/t gold and 108.1 g/t silver (7.68 g/t Au Eq.).

Holes CU22-08 and CU22-09 may represent an area between higher grade and thicker "shoots", but nonetheless demonstrate the continuity of the mineralized structure. Results are detailed in Table 1.

The emerging Cuyes West structure is similar to the Camp deposit and contains multiple structures into which rhyolite dikes have been emplaced. Mineralization typically occurs in and along the contacts of these structures. Both deposits are interpreted to be hosted in large scale "ring-fractures" centred around the Los Cuyes Diatreme (See Figure 1).  

At Cuyes West and Camp, the gold-bearing mineralization style is quite recognizable, with pyrite and sphalerite breccias, veins and disseminations, often with marcasite and rhodochrosite, and rarely other sulphides. Drilling has been ongoing at Cuyes West with step-outs based on logged mineralization. Holes that have been drilled, for which results are pending, are shown in Figure 2. Geological logging of hole CU22-12, a 50 metre, near-vertical step-out on hole CU22-05 is of particular note, as it contains a seven-metre intercept resembling the five-metre intercept cut in hole CU22-05 from 277m: five metres grading 29.43 g/t gold and 86.5 g/t silver (30.47 g/t Au Eq). Intervals shown in Figure 2 represent the primary interval for the zone. Other intervals are present in parallel structures that are not presented as pierce points in Figure 2.

At the Ruiz structure, the results of a fan of three shallow holes drilled from the southwest to test the upper part of Ruiz intersected a consistent gold bearing structure, as shown in Figure 3, with results listed in Table 1.  Hole RZ22-01 also contained a 22-metre intercept grading 0.36 g/t gold and 26.8 g/t silver (0.68g/t Au Eq) as disseminated pyrite and sphalerite mineralization in a diatreme host rock, resembling the Los Cuyes deposit. This area will be the focus of future surface mapping to better define the diatreme body. The interpretation of the intersection of the Cuyes West and Ruiz structures is developing as drilling in this area continues.

All Luminex sample assay results have been independently monitored through a quality control / quality assurance ("QA/QC") protocol which includes the insertion of blind standards, blanks as well as pulp and reject duplicate samples. Logging and sampling are completed at Luminex's core handling facility located at the Condor property. Drill core is diamond sawn on site and half drill-core samples are securely transported to ALS Laboratories' ("ALS") sample preparation facility in Quito, Ecuador. Sample pulps are sent to ALS's lab in Lima, Peru for analysis where gold content is determined by fire assay of a 50-gram charge with ICP finish. 
Silver and other elements are also determined by ICP methods. Over-limit samples assaying greater than 10 g/t gold and 100 g/t silver are re-analyzed by ALS using fire assay with a gravimetric finish. Luminex is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. ALS Laboratories is independent of Luminex.
