Luminex Hits with Cuyes West Step-out Holes: 4.0m Grading 19.35 g/t Au Eq and 2.5m Grading 18.54 g/t Au Eq

Cuyes West Drilling Highlights:

  • CU22-12 – 2.5 metres grading 18.54 g/t Au Eq
  • CU22-13 – 36.0 metres grading 2.29 g/t Au Eq
  • CU22-14 – 4.0 metres grading 19.35 g/t Au Eq; including 2.0 metres grading 36.59 g/t Au Eq
  • CU22-15 – 17.5 metres grading 3.07 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 six holes (CU22-10 to CU22-15) at Cuyes West. Drilling has confirmed a strike length of approximately 350 metres, while the anomaly has been mapped at surface for more than 500 metres. The drilled vertical extent of the Cuyes West mineralized structure now exceeds 300 metres. All holes have now been reported from the 2022 program, except for CU22-16 and CU22-17 (completed in January). Drilling at Cuyes West is continuing with one rig; a second rig is on standby to drill Prometedor as soon as trail and pad construction are complete. Drilling of Prometedor is expected to start by March.

Marshall Koval, CEO and Director commented: “The continued positive results at Cuyes West are putting Luminex on a path to having two sources of underground material at Condor North. Adding a Cuyes West underground resource in addition to the existing Camp underground resource will be crucial for Luminex’s plan to start with a smaller throughput mill, with lower initial capital than what was planned in the 2021 Preliminary Economic Assessment.”

Hole CU22-12 intersected 2.5 metres from 323 metres grading 16.28 g/t gold and 188.1 g/t silver (18.54 g/t Au Eq). This hole stepped out approximately 50 metres vertically below hole CU22-05, which intersected 5.0 metres of 29.43g/t gold and 86.5g/t silver (30.47g/t Au Eq), indicating continued high-grade mineralization at depth.

Hole CU22-14 intersected multiple high-grade structures, notably 4.0 metres from 216 metres down hole of 18.91 g/t gold and 36.6 g/t silver (19.35 g/t Au Eq), including 2.0 metres of 35.8 g/t gold and 65.7 g/t silver (36.59 g/t Au Eq). The Cuyes West structure was intersected at 275 metres over 16 metres grading 3.04 g/t gold and 12.5 g/t silver (3.19 g/t Au Eq).

Hole CU22-15, stepped out approximately 60 metres east of CU22-13 and approximately 80 metres below hole CU22-02. It intersected 17.5 metres from 240.5 metres grading 3.00 g/t gold, 6.1 g/t silver (3.07 g/t Au Eq). Other intervals are present in parallel structures that are not presented as pierce points in Figure 2 but are detailed in Table 1.

Figure 1. Plan map showing location of the Camp, Cuyes, and Cuyes West deposits.

At Cuyes West, rhyolite dike contacts and high angle faults are mineralized. The mineralization extends into wall rock, occurring as pyrite, sphalerite, marcasite and rhodochrosite veins and as disseminations. This style of mineralization is identical to that at the Camp deposit, 300m to the southwest, and these deposits may connect at depth. At a property scale, the mineralized structures and dikes are interpreted to be “ring-fractures” around the Los Cuyes Diatreme (See Figure 1).

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 14.95 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 35.80 g/t Au. Au Eq values assume $1,500 gold and $18.00 silver (Au Eq= Au g/t + (Ag g/t *0.012)). There is insufficient geological data to calculate true thickness for the intervals reported in this table.

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.
