The optimized Phase 2 infill drilling program at El Domo was successfully completed in late December 2018 on the open-pit constrained Mineral Resource, for a full year total of 12,608 metres of infill drilling between both phases of the work program. The final 2018 drilling results are detailed in this news release.

Adventus has engaged Roscoe Postle and Associates Inc. ("RPA") to produce a Preliminary Economic Assessment ("PEA") for the Curipamba project that will include a Mineral Resource update with all 2018 drilling results. RPA has also been retained to conduct additional engineering work including but not limited to overseeing the ongoing metallurgical work at Base Metallurgical Laboratories Ltd. ("BML") announced in the September 19, 2018 news release.

The Partners are also planning additional exploration drill holes in 2019 at the Curipamba, Pijili and Santiago projects in Ecuador after completion of a MobileMT airborne geophysical survey. The survey contractors have recently completed work at the Pijili project and are currently working at the Santiago project. When the survey is completed at the Santiago project, the airborne geophysical equipment will be moved to Curipamba for immediate use. Following the processing of acquired geophysical data, a detailed target generation initiative will commence, and diamond drills will be deployed to test newly developed exploration targets.

CURI-337 intersected a faulted, gold-rich grainstone unit from 107.00 to 119.88 metres, grading 0.23% copper, 2.41 g/t gold, 0.97% zinc, 49.3 g/t silver, and 0.22% lead.

Drill holes CURI-325, CURI-327, CURI-329 and CURI-331 were designed to test the limits of the known massive sulphide mineralization and further assess the pit wall geology. These drill holes all intersected favourable strata; however, no semi-massive to massive sulphide mineralization was intersected, but rather narrow, sporadic low-grade hydrothermal breccia units in footwall dacite volcaniclastic rocks. CURI-335, which was also designed for the same purpose, did intersect 4.87 metres of low-grade hydrothermal breccia mineralization from 48.80 to 53.67 metres grading 0.58% copper, 0.15 g/t gold, 3.80% zinc, 12.1 g/t silver and 0.01% lead.

Other Results

In the Sesmo area, technical staff conducted a thorough assessment of 2018 drill holes due to the subtle nature of mineralization in order to relate their observations back to study positive assay results from CURI-254, CURI-254A, and CURI-274 (see April 30, 2018 and September 6, 2018 news releases). Several drill holes were selected for resampling including CURI-258, CURI-263, CURI- 267 and CURI-271, but except for some geochemically anomalous narrow intervals, no significant results have been returned. Subsequent drill holes CURI-307, CURI-308, CURI-313, and CURI-321 at the main showing similarly returned geochemically anomalous narrow intervals, and no significant results. Technical staff are continuing their assessment of this interesting target area through prospecting, geological mapping, and 2019 airborne geophysical survey results to further enhance future targeting.

Technical Information and Quality Control & Quality Assurance ("QAQC")

The Curipamba project work program is being managed and reviewed by Vice President Exploration, Jason Dunning, M.Sc., P.Geo., a Qualified Person within the meaning of NI 43-101. Salazar staff collect and process samples that are securely sealed and shipped to Bureau Veritas ("BV") in Quito for sample preparation that includes crushing and milling to prepare pulps that are then split for shipment to their facility in Lima, Peru for analysis. All assay data have undergone internal validation of QAQC; noting there is an established sampling control program with blind insertion of assay blanks, certified industry standards and sample duplicates for the Curipamba project. A QAQC program is also in place at BV and includes insertion of blanks, standards and duplicate reanalysis of selected samples. BV's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. At BV, gold is analyzed by classical fire assay techniques with an ICP-AES finish, and both silver and base metals are analyzed by a 44-element aqua regia ICP-AES technique. Overlimit protocols are in place for gold, silver, copper, lead, and zinc. 

Infill drilling continues to yield intercepts of high-grade, copper- and gold-rich semi-massive to massive sulphide mineralization within the open-pit constrained Mineral Resource update for the El Domo VMS deposit completed by RPA. The Indicated Mineral Resource totals 8.8 million tonnes grading 1.62% copper, 2.34 g/t gold, 2.42% zinc, 48.0 g/t silver, and 0.27% lead. The Inferred Mineral Resource totals 2.6 million tonnes grading 1.29% copper, 1.09 g/t gold, 1.51% zinc, 29.0 g/t silver, and 0.14% lead (see January 31, 2018 news release). The National Instrument ("NI") 43-101 Technical Report was authored by Independent Qualified Person Dr. Lars Weiershäuser, P.Geo., of RPA (based in Toronto, Ontario, Canada) who is a Qualified Person as defined by NI 43-101.
