Cuyes West Drilling Highlights:

• CU23-20 – 211.0 metres grading 1.18 g/t Au Eq, including 20.0 metres grading 4.78 g/t Au Eq
• CU23-22 – 211.0 metres grading 1.16 g/t Au Eq, including 15.0 metres grading 6.68 g/t Au Eq

Vancouver, British Columbia – Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the “Company” or “Luminex”) is pleased to announce drill results from four holes (CU23-19 to CU23-22) at Cuyes West. The previously announced widening hanging wall mineralization adjacent to Cuyes West has expanded into a new breccia pipe with this added drilling yielding longer than 200 metre intervals of gold mineralization over one gram per tonne. Step out drilling from this new breccia pipe and Cuyes West is ongoing, which will contribute towards updating the resource for Condor North to include all Cuyes West drilling by Q4 2023.

Marshall Koval, CEO commented: “We are extremely happy with the discovery of a coherent breccia zone containing substantial mineralization, that widens to widths of more than 200 metres. The area is completely open to depth and may have a significant positive impact on the project”.

Hole CU23-22 intersected multiple high-grade structures in the breccia pipe, notably 15.0 metres of 6.68 g/t Au Eq, which included 3.0 metres from 316.0 metres grading 23.71 g/t gold and 156.4 g/t silver (25.59 g/t Au Eq) and a wider intercept of 211.0 metres from 177 metres grading 1.01 g/t gold and 12.9 g/t silver (1.16 g/t Au Eq).

CU23-20 intersected 20.0 metres grading 4.23 g/t gold and 45.4 g/t silver (4.78 g/t Au Eq) from 264.0 metres in the breccia pipe, within a broader intercept of 211.0 metres from 134.0 metres grading 1.07 g/t gold and 9.4 g/t silver (1.18 g/t Au Eq).

Hole CU23-21 intersected multiple high-grade intercepts, including 1.0 metre of 9.50 g/t gold and 181.0 g/t silver (11.67 g/t Au Eq) from 285.0 metres, within a broader 96.0 metres of 0.95 g/t gold and 15.6 g/t silver (1.14 g/t Au Eq) from 213.0 metres. This hole stepped out approximately 100 metres vertically on Cuyes West below hole CU22-14, which hit 16.0 metres of 3.04 g/t gold and 12.5g/t silver (3.19g/t Au Eq) from 275.0 metres. Hole CU23-21 is plotting at the fringe of the newly discovered breccia body along the Cuyes West structure. More step out drilling is required to fully define the extent of the new breccia body and to determine how this will impact the resource for this area (see Figure 2).

Other intervals are present in additional structures in holes CU23-19, CU23-20, CU23-21 and CU23-22 and are detailed in Table 1.

The style of mineralization at Cuyes West is identical to that at the Camp deposit, 600 metres to the west. At a property scale, these mineralized structures are interpreted to be hosted in ring and radial fractures around the Los Cuyes caldera (See Figure 1). The new breccia pipe consists of a dacite porphyry-breccia; mineralization occurring mainly as crackle and mosaic style hydrothermal breccias with sulphide rich matrix and volcaniclastic clasts, that also contain mineralization.

Luminex is currently drilling CU23-26 and has drilled a total of 3,865 metres in 2023 at Cuyes West. Additionally, Luminex has finished five holes at Prometedor for a total of 824 metres and is awaiting assays. The second drill rig has been moved to the Esperanza gold-silver target, located approximately 500 metres south of Prometedor. One drill hole is planned, targeting gold-silver mineralization in sulphides that occurs along the contacts of rhyolite dikes, in a setting very similar to the Camp deposit.

Table 1. Drill intercepts for Cuyes West drill holes. Asterisked intervals are shallower and belong to the diatreme at Los Cuyes (see note below).

Asterisked (*) intervals are “Shallower” intervals 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 9.49 g/t Au. Remaining intervals not marked with an asterisk are for “Deeper” intervals calculated using a lower limit of 1.0 g/t Au with a maximum inclusion of up to six continuous metres below cut-off and the highest gold value used in the reported weighted averages is 55.40 g/t Au. Au Eq values assume $1,500 gold and $18.00 silver (Au Eq= Au g/t + (Ag g/t *0.012)).

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.
