(TSXV: LR) (US OTC: LUMIF) (the “Company” or “Luminex”) is pleased to announce a maiden mineral resource estimate at the Camp deposit and updated mineral resource estimates for the other deposits at the Company’s Condor project, located in Zamora-Chinchipe Province, southeast Ecuador. The Camp deposit mineral resource estimate is the culmination of 2019 and 2020 drilling totaling 28 holes. Luminex is continuing work to expand this exciting new area of the Condor project. The mineral resource updates on the four other deposits at the Condor project are based on previous drilling, but with updated metal price assumptions.The Camp deposit comprises a planar, sub-vertical and relatively high-grade mineralized zone, with thickness and continuity that exhibit reasonable prospects for eventual economic extraction using underground extraction methods. The estimate of mineral resources is presented in Table 1. The sensitivity of mineral resources to the cut-off grade is shown in Table 2.The reported Camp deposit resource is open to depth, where the deepest hole in the zone, previously reported hole CC19-12, intercepted 3.8 metres true width grading 6.09 g/t gold and 36.3 g/t silver at approximately 600 meters vertical depth, cut over 19.3 meters core length from 646.0 to 665.3 metres down the hole. In addition, the Camp deposit resource remains open laterally to the southwest where it is thought the Soledad Bajo zone may connect it to the resources reported herein for the Soledad deposit. The Camp deposit resource also remains open to the northwest where surface mapping and sampling indicates the Camp NW target may represent its northwestern extension, displaced approximately 100 metres to the north by a fault (see Figure 1). At a project scale, the Camp deposit lies at the northwest end of a more than four kilometre gold and silver mineralized trend extending towards Luminex’s Prometedor target.Camp Deposit Work PlanDrill test the Soledad Bajo targetExpand deep high-grade area with further drillingContinue surface exploration to advance the NW Camp area to drill stageContinue sampling and mapping at Prometedor and build access for drill padsComplete metallurgical work that is currently underway (see details below)Table 1: Estimate of Inferred Mineral Resources for the Camp Deposit (1.50 g/t AuEq Cut-off Grade)Mineral resources exhibit reasonable prospects of eventual economic extraction using underground extraction methods. The base case cut-off grade is 1.50 g/t gold equivalent (AuEq) where: AuEq = Au g/t + (Ag g/t × 0.012) + (Cu% × 1.371) + (Pb% × 0.457) + (Zn% × 0.571).

Table 3: Summary of the Mineral Resource Estimates for All Deposits Located at the Condor ProjectThe contained gold resource increased by 0.2 million ounces in the indicated mineral resource category and 0.2 million ounces in the inferred mineral resource category across the Los Cuyes, Soledad, Enma and Santa Barbara deposits collectively. For consistency across the deposits, it was necessary to update gold price in the mineral resource estimate assumptions from US$1,400/oz to US$1,500/oz, which was the main driver in the increase in contained gold ounces.Notes:
(1) The mineral resource estimate has an effective date of March 4, 2020. (2) There are no known issues related to legal, political or environmental issues that could materially affect the potential development of the mineral resources. (3) The quantity and grade of reported inferred mineral resources is based on limited geological evidence and sampling which is sufficient to imply but not verify geological and grade or quality continuity and there has been insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource. It is reasonable to expect that the majority of inferred mineral resources could be upgraded to indicated or measured mineral resources with continued exploration. (4) Gold equivalent (AuEq) values were calculated using the following prices: a gold price of US$1,500 per ounce, a copper price of US$3.00 per pound, a zinc price of $1.25/lb, a lead price of $1.00/lb and for a silver price of US$18 per ounce. Gold equivalent values at the Camp deposit are calculated using the following formula: AuEq = Au g/t + (Ag g/t x 0.012) + (Cu% x 1.371) + (Pb% x 0.457) + (Zn% x 0.571). Gold equivalent grades at the other deposits are calculated using the formula  AuEq = Au g/t + (Ag g/t x 0.012) + (Cu% x 1.371)   (5) The base case cut-off grade is 0.35 g/t AuEq for pit constrained mineral resources at the Soledad, Los Cuyes, Santa Barbara and Enma deposits limited inside $1,500/oz Au pit shells. The cut-off grade for mineral resources considered amenable to underground extraction methods at the Camp deposit is 1.50 g/t AuEq.
Camp Deposit GeologyThe Camp deposit is classified as an intermediate sulphidation epithermal gold-silver deposit. The deposit currently comprises a steeply northeast dipping coherent panel of mineralization of variable thickness that extends from surface to approximately 600 metres vertical depth and 400 metres along strike. There are also a number of smaller parallel zones in the footwall and hanging wall. Mineralization is controlled by high angle feeder structures and high angle rhyolite dikes emplaced into granodiorite. These acted as impermeable barriers against which mineralizing fluids were focused. Mineralization consists of veins, breccias and dissemination and occurs as pyrite, marcasite, sphalerite and galena, often with chalcopyrite, within an envelope of sericite, clay and carbonate alteration, often occurring as rhodochrosite.Camp Deposit Metallurgy Work PlanAn initial screening metallurgical testing program for the Camp deposit is underway at C. H. Plenge & CIA S.A. (“Plenge”), an independent metallurgical testing laboratory based in Lima, Peru. The program is designed to test gravity concentration, cyanidation as well as the polymetallic (Au, Ag, Cu, Pb, Zn) flotation response. A total of 341kgs of ¼ drill core from 19 drill holes were sent to Plenge for testing. This includes high, medium and low-grade samples. Results for the program are expected by end of Q2 2020.Figure 1: Plan Map of Northern Condor Epithermal Deposits
Mineral Resource Estimate for the Camp Deposit
This mineral resource estimate for the Camp deposit was prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and was based on a total of 14,801 m of diamond drilling in 28 holes. The mineral resource estimate was generated using drill hole sample assay results and the interpretation of a geological model which relates to the spatial distribution of gold, copper, silver, lead and zinc. Sample data was collected following accepted industry procedures and analyzed by accredited commercial assayers and tracked by quality assurance and quality control programs that meet industry standards. Interpolation characteristics were defined based on the geology, drill hole spacing, and geostatistical analysis of the data. The effects of potentially anomalous high-grade sample data, composited to 2 metre intervals, are controlled by limiting the distance of influence during block grade interpolation. For example, composited samples greater than 15 g/t gold are limited to a maximum distance of influence of 35m during block grade estimation. Individual blocks in the resource block model measure 5 x 5 x 5 metres in size. Block grades are estimated using ordinary kriging and have been validated using a combination of visual and statistical methods. Inferred mineral resources include model blocks that are within a maximum distance of 75 metres from a drill hole. Using projected technical and economic parameters, the Camp deposit forms a planar, sub-vertical zone of mineralization with thickness and continuity of grade, at a base case cut-off threshold of 1.50 g/t AuEq, that is considered to exhibit reasonable prospects for eventual economic extraction using bulk underground extraction methods. Note that these assumptions are used for reporting mineral resources and should not be interpreted to represent a mineral reserve. There are no mineral reserves at the Camp deposit.The approaches used to estimate the mineral resources for the other deposits located on the Condor project are described in a technical report dated July 10, 2018 and filed on Luminex’s profile on SEDAR ( updated NI 43-101 technical report detailing the mineral resource estimate for the Condor Project will be completed and filed on SEDAR ( and Luminex’s website ( within 45 days.Quality Assurance for the Camp DepositAll 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 project. 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 is independent of Luminex.Qualified PersonsRobert Sim, P.Geo., a Qualified Person as defined by NI 43-101, is responsible for the estimate of mineral resources presented in this news release and has reviewed, verified and approved the contents of this news release as they relate to the mineral resource estimate and the data underlying the mineral resource estimate.
