Highlights:

• CU22-03 – 4.0 metres of 5.5 g/t Au Eq

• CU22-05 – Intercepted Cuyes West structure and a new mineralized structure; assays pending

Vancouver, British Columbia – Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the “Company” or “Luminex”) is pleased to announce that after assay results from four of five completed holes, it has drill-delineated at least 200 metres of strike length at the Company’s high-grade gold and silver discovery, that it is referring to as Cuyes West. The additional step-out holes were drilled after the initial discovery announced in the March 14, 2022 news release. In addition to the drilling, the Company has discovered a new mineralized structure, the Ruiz structure, which is parallel to the Camp deposit and has also identified other similar targets for potential future testing at Condor North.

Marshall Koval, CEO & Director commented: “The existing underground Camp deposit provides early, high grade gold mineral resources in the Condor North PEA to blend with the three open pits. Additional similar underground areas such as Cuyes West, the Ruiz structure and other newly discovered targets should continue to enhance the Condor North project.”

Cuyes West Structure

Cuyes West is located in a previously untested area immediately west of the Los Cuyes mineral resource. To date, four lateral step-out holes on hole CU21-01 have been completed to begin delineating the Cuyes West structure (see Figure 2). CU21-01 intercepted 17.6 metres (278.4 to 296.0 metres) and graded 2.91 g/t gold and 15.23 g/t silver (3.09 g/t AuEq), with an internal zone of 8.6 metres grading 5.1 g/t gold and 24.85 g/t silver (5.39 g/t AuEq.).  Luminex has received assay results for three of the four holes (see Table 1).

Table 1. Drill intercepts for Cuyes West holes.

Intervals, except those marked with an asterisk (*), are calculated using a lower limit of 1.00 g/t Au with a maximum inclusion of up to five continuous metres below cut-off and the highest gold value used in the reported weighted averages is 15.75 g/t Au. Asterisked intercepts are calculated using a lower limit of 0.20 g/t Au with a maximum inclusion of ten continuous metres below cut-off occurring within the stated intercept and the highest gold value used in the reported weighted averages is 2.03 g/t Au. Eq values assume $1,500 gold and $18.00 silver (AuEq= Au g/t + (Ag g/t *0.012).

Drill hole CU22-03 stepped out approximately 70 metres to the south of CU21-01 and intercepted 4.0 metres grading 5.04 g/t gold and 38.3 g/t silver, for 5.50 g/t AuEq., from 262 metres contained within a 22.0-metre interval grading 1.88 g/t gold and 20.5 g/t silver (2.13 g/t AuEq.) (see Figures 2 and 3). On the basis of this successful step-out hole Luminex stepped out a further 80 metres to the south with hole CU22-04, that intercepted 4.0 metres grading 6.38 g/t gold and 108.1 g/t silver (7.68 g/t AuEq.), from 214 metres.

Drill hole CU22-05 was drilled to step out on CU22-04 and intercepted the projected mineralised structure over approximately 7 metres from 186 metres. This represents a step-out of approximately 120 metres to depth and 50 metres laterally. Assays from this intercept have not been received and grades are unknown.

Drill hole CU22-02 stepped out approximately 50 metres to the north of CU21-01 and intercepted 6 metres grading 1.31 g/t gold and 17 g/t silver (1.51 g/t AuEq.), from 321 metres with 134 metres grading 0.81 g/t gold and 4.4 g/t silver (0.86 g/t AuEq.) and 40 metres grading 0.37 g/t gold and 0.9 g/t silver (0.38 g/t AuEq.) from surface higher up in the hole. Artisanal workings and surface sampling indicate that the structure also continues to the north, but hole CU22-02 represents a thinning of the structure. Further work to establish the northward extension is required.

Ruiz Structure

The Ruiz structure connects to the Cuyes West structure from the north at a high angle (see Figure 1 and Figure 4). Luminex geologists extended hole CU22-05 to intersect this structure and, at the predicted depth, the hole cut approximately 18 metres of disseminated and centimetric vein sulphides from 266 metres, including 50 centimetres of semi massive sulphides at 280 metres. Assays from this intercept have not been received and grades are unknown. Luminex is testing this structure with a second drill hole, drilled to the north-northeast having designed the hole to intersect the structure at a vertical depth of approximately 70 metres. This drill hole is shown on Figure 1 and Figure 4.

District Context

Both the Cuyes West and Ruiz structures consist of pyrite, sphalerite, marcasite disseminated along rhyolite dike contacts that is associated with illite, sericite, silica and carbonate (locally rhodocrosite) alteration. This style of mineralization is identical to the Camp deposit located approximately 700 metres to the south-southwest (see Figure 4) and is classified as intermediate sulphidation type. The Camp deposit hosts an inferred resource of 6.0 Mt with 663,000 Au Eq oz, with a gold and silver grade of 3.28 g/t and 27.8 g/t respectively. Luminex geologists have identified additional structures at Condor North that have similar characteristics and may constitute future drill targets.

Future Plans

At Condor North, Luminex plans to:

1. Continue to delineate a resource at Cuyes West;
2. Continue to drill test the Ruiz structure;
3. Continue step-out and infill drilling at the Camp deposit; and
4. Explore similar intermediate sulphidation targets and bring them to drill stage.

Quality Assurance

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.
