Three higher-grade subsets occur in this intercept, from 103.08 to 108.13 metres, 123.80 to 153.12 metres, and then from 133.39 to 142.50 metres. The first intercept is semi-massive sulphide mineralization grading 6.01% copper, 1.59 g/t gold, 1.53% zinc, 26.1 g/t silver and 0.14% lead (7.70% CuEq). The second intercept is massive sulphide mineralization grading 6.21% copper, 1.70 g/t gold, 0.15% zinc, 22.4 g/t silver and 0.04% lead (7.51% CuEq) and the third intercept is also massive sulphide mineralization grading, 11.65% copper, 2.41 g/t gold, 0.16% zinc, 44.7 g/t silver, and 0.03% lead (13.58% CuEq). A section of mineralized footwall felsic autoclastic volcanic rocks was intersected from 169.00 to 176.40 metres, grading 0.06% copper, 0.27 g/t gold, 0.41% zinc, and 9.2 g/t silver and 0.07% lead (0.45% CuEq).

Drill hole CURI-374 intersected semi-massive sulphide from 92.54 to 98.10 metres, grading 2.32% copper, 15.37 g/t gold, 21.91% zinc, 403.0 g/t silver, and 3.09% lead (22.58% CuEq).

All results from the completed infill definition drilling program are to be used in updating the Mineral Resource estimate for El Domo in 2021. The updated Mineral Resource estimate will be part of the ongoing feasibility study for the development of the El Domo (see December 2, 2020 news release). Figure 1 illustrates the drill locations for the results of the four drill holes outlined in this news release and the holes currently in the assay lab, or in progress. Drill collar location coordinates are summarized for the infill and geomechanical drilling programs in Table 1 at the end of this news release.

For reference, the last Mineral Resource estimate completed in accordance with NI 43-101 for El Domo was published as part of the preliminary economic assessment report titled: "Technical Report on the Preliminary Economic Assessment for the Curipamba Project – El Domo Deposit, Central Ecuador", with an effective date of June 14, 2019 on SEDAR.

Technical Information and 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 or Vancouver, Canada 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, samples from the El Domo infill drilling have gold analyzed by classic fire assay techniques with an AAS finish, while silver and base metals are analyzed by a 44-element aqua regia technique with ICP-AES finish. For regional drilling, silver and base metals are analyzed by a 45-element 4 acid technique with ICP-MS finish. Overlimit protocols are in place for gold, silver, copper, lead, and zinc.
