El Domo Infill Drilling Results
The infill drilling program commenced in early March 2018 with the objective of upgrading the confidence level of the higher-grade portion of the open-pit constrained Mineral Resource by decreasing drill spacing; which will also generate material for a planned metallurgical program in the second half of 2018. To date, drilling within higher-grade portion of the open-pit constrained Mineral Resource has successfully completed 34 out of 52 drill holes with two drill holes in progress. Approximately 6,060 metres from a planned 7,500 metre work program has been successfully completed, and this phase of infill drilling is expected to be completed by mid-third quarter 2018.
Drill hole CURI-270 intersected massive sulphide mineralization from 55.60 to 59.72 metres for an approximate true thickness of 3.91 metres, grading 2.27% copper, 14.31 g/t gold, 33.36% zinc, 526.8 g/t silver, and 3.78% lead. A subset interval of massive sulphide mineralization possesses significantly higher-grade zinc from 57.85 to 59.72 metres, grading 3.07% copper, 6.32g/t gold, 49.73% zinc, 255.4 g/t silver, and 1.69% lead.

Drill hole CURI-275 also intersected low-grade stockwork directly underneath the massive sulphide mineralization from 62.00 to 67.43 metres for an approximate true thickness of 4.89 metres grading 0.25% copper, 0.35 g/t gold, 1.23% zinc, 10.2 g/t silver, and 0.07% lead.
Massive sulphide mineralization in drill hole CURI-277 has been caught up in a fault zone from 66.25 to 68.80 metres, so a representation of the true thickness may not be accurate. However, the mineralization has an apparent true thickness of 2.42 metres, grading 2.99% copper, 7.52 g/t gold, 9.51% zinc, 177.3 g/t silver, and 0.94% lead.

Drill hole CURI-277 also intersected a wide section of low-grade stockwork below the massive sulphide mineralization from 85.36 to 96.30 metres for an approximate true thickness of 10.39 metres grading 0.62% copper, 0.14 g/t gold, 1.71% zinc, 5.5 g/t silver, and 0.04% lead. A subset interval of higher-grade gold content occurs from 94.42 to 96.30 metres grading 1.61% copper, 0.06 g/t gold, 7.50% zinc, 8.0 g/t silver, and 0.03% lead.
Drill hole CURI-255 was designed to test the southerly limits of the known massive sulphide mineralization and further assess the pit wall geology. This drill hole intersected favourable strata including both the grainstone, which is a resedimented volcaniclastic unit containing pebbles and cobbles of massive sulphide mineralization, and a fine-grained felsic volcaniclastic tuff-sized material known to occur directly above the massive sulphide mineralization; however, no semi-massive to massive sulphide minerals were intersected. CURI-269 also did not intersect massive sulphide mineralization; however, it did intersect a low-grade stockwork zone within dacite volcaniclastic rocks from 86.50 to 98.37 metres that corresponds to other similar low-grade stockwork zones stratigraphically below El Domo. These drill holes confirmed modelling done by RPA along the margins of the deposit and provide excellent geological control for future modelling studies.
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 Roscoe Postle Associates Inc. ("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.
