Luminex Intercepts 21 Metres of 4.26 g/t Gold and 26.3 g/t Silver and Recommences Drilling

VANCOUVER, April 28, 2020 - Luminex Resources Corp. (TSXV: LR) (US OTC: LUMIF) (the “Company” or “Luminex”) is pleased to release Condor Camp deposit drilling results for hole CC20-29 and announce that it is recommencing drilling at the Condor project. The Company has completed approximately 17,800 metres in 32 holes at the Camp deposit since the campaign began and results from CC20-30 to CC20-32 are still pending. Hole CC20-29 and subsequent holes were not included in the maiden mineral resource estimate for the Camp deposit that was released March 31, 2020.

Step-out hole CC20-29 intercepted a new high-grade area measuring 21 metres core length from 617.0 to 638.0 metres grading 4.26 g/t gold and 26.3 g/t silver. The intercept included 4.0 metres core length from 630.0 to 634.0 metres grading 10.53 g/t gold and 42.8 g/t silver. This intercept is located at approximately 530 metres vertical depth and is approximately 110 metres horizontally from the previously reported intercept in hole CC19-12 and approximately 280 metres south-southwest and approximately 50 metres below the previously reported interval in hole CC19-23 (Figure 2). More drilling is needed to determine the geological data required to calculate true widths for the intercepts.

Luminex has elected to restart drilling on a limited basis. Drilling will focus on Soledad Bajo, the immediate southeast surface extension of the Camp deposit (Figure 1 and 3), using one drill rig running a single daily 12-hour shift. The Government of Ecuador has mandated that companies in “Strategic Industries”, a denomination that includes mining, may continue operations during the COVID-19 State of Exception. Luminex continues to follow the Ecuadorian health and safety requirements as well as strict in-house safety protocols developed to minimize risk to employees and contractors from COVID-19. To date the Company has had no occurrences of COVID-19 at its Condor project. Employees and contractors are screened and tested prior to any personnel shift changes at the project.

Table 1: Drill hole results.

Intervals calculated using a lower limit of 0.5 g/t Au with a maximum inclusion of up to four continuous metres below cut-off and the highest gold and silver values used in the reported weighted averages are 24.9 g/t Au and 99.9 g/t Ag. More drilling is needed to determine the geological data required to calculate true widths for the intercepts.

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.
