Drill hole CURI-342 intersected a narrow section of high-grade copper and gold-rich massive sulphide mineralization from 95.60 to 97.50 metres, grading 3.04% copper, 16.41 g/t gold, 17.94% zinc, 181.2 g/t silver and 2.23% lead (24.41% CuEq). Stratigraphically beneath the massive sulphide is a well mineralized felsic autobreccia in the footwall rocks intersected from 97.50 to 107.50 metres, grading 0.49% copper, 0.26 gpt gold, 0.41% zinc, 9.6 gpt silver and 0.05% lead (0.95% CuEq). This includes a higher-grade subset from 97.50 to 99.50 metres, grading 1.26% copper, 0.61 gpt gold, 1.18% zinc, 24.1 gpt silver and 0.17% lead (2.44% CuEq).

CURI-343 intersected a well-mineralized fine-grained tuffaceous volcaniclastic in the hanging wall of the massive sulphide mineralization from 99.38 to 101.90 metres, grading 0.84% copper, 1.92 g/t gold, 2.67% zinc, 37.0 g/t silver, and 0.10% lead (3.67% CuEq). The massive sulphide mineralization was intersected from 101.90 to 103.40 metres, grading 2.45% copper, 9.09 g/t gold, 12.01% zinc, 211.7 g/t silver, and 1.96% lead (16.38% CuEq). A higher-grade subset was intersected from 101.90 to 102.50 metres, grading 4.68% copper, 21.30 g/t gold, 28.11% zinc, 491.0 g/t silver, and 4.79% lead (37.30% CuEq).

CURI-344 intersected a well-mineralized grainstone in the hanging wall of the massive sulphide mineralization from 57.32 to 62.26 metres, grading 5.60% copper, 8.99 g/t gold, 4.02% zinc, 151.0 g/t silver, and 0.56% lead (15.60% CuEq). The high-grade massive sulphide mineralization was intersected from 62.26 to 68.40 metres, grading 14.91% copper, 21.02 g/t gold, 10.39% zinc, 255.3 g/t silver, and 0.75% lead (37.48% CuEq). A higher-grade subset was intersected from 62.26 to 66.48 metres, grading 19.11% copper, 24.36 g/t gold, 10.93% zinc, 309.5 g/t silver, and 0.83% lead (45.00% CuEq). At the base of the high-grade massive sulphide is a narrow intercept of semi-massive sulphide mineralization from 68.40 to 70.12 metres, grading 0.31% copper, 0.81 gpt gold, 3.11% zinc, 9.0 gpt silver and 0.01% lead (2.14% CuEq). Stratigraphically beneath the massive sulphide in CURI-344 is a well mineralized felsic autobreccia in the footwall rocks intersected from 70.12 to 80.13 metres, grading 0.61% copper, 0.74 gpt gold, 0.27% zinc, 4.1 gpt silver and 0.01% lead (1.31% CuEq). This includes a higher-grade subset from 72.93 to 75.89 metres, grading 1.81% copper, 1.53 gpt gold, 0.83% zinc, 7.9 gpt silver and 0.01% lead (3.36% CuEq).

All results from the current infill definition drilling program will be used to update the Mineral Resource estimate for the El Domo deposit in 2021. The updated Mineral Resource estimate will be part of the ongoing feasibility study for the development of the El Domo deposit (see December 2, 2020 news release).

For reference, the last Mineral Resource estimate 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 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 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. Overlimit protocols are in place for gold, silver, copper, lead, and zinc.
