Drill holes CURI-371, CURI-375, CURI-376, CURI-380 and CURI-383 were designed for collection of geomechanical data to

assist in future mine planning, as part of the ongoing feasibility study. Drill hole CURI-388 intersected a low-grade section

of footwall mineralized felsic autoclastic volcanic rocks 102.04 to 112.39 metres, grading 0.04% copper, 0. 17 g/t gold,

0.09% zinc, 4.0 g/t silver and 0.02% lead (0.21% CuEq) for an approximate true thickness of 6.73 metres.

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 El Domo (see December 2, 2020 news release). Figure 1 illustrates the drill locations for the results of the

ten 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 NI 43-101 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.

Curipamba – Regional Exploration Drilling Program Update

Upon completion of infill and geomechanical drilling required to support the ongoing Feasibility Study with a Mineral

Resource estimate update and the provision of metallurgical samples (see December 2, 2020 news release), a drill rig was

tasked to restart the regional exploration drilling program. A total of 4,000 metres is budgeted in 2021 with drilling having

re-commenced on the El Panecillo target in late April 2021, approximately 1.5 kilometres east of El Domo. El Panecillo is a

VMS target being drilled for the first time in the same favourable volcanic-sedimentary strata that hosts El Domo. The first

drill hole, CREG-004, has been completed with CREG-005 in progress. Results from the regional exploration work program

will be released after receipt from the laboratory and when results pass a rigorous internal quality assurance and quality

control (“QAQC”) processes.

The regional exploration drilling program started in October 2020 approximately 8 km southwest of El Domo (see

December 21, 2020 news release) on the La Vaquera and Sesmo Sur targets. Two drill holes were completed on the La

Vaquera target and one drill hole was completed on the Sesmo Sur target. Although propylitic alteration was observed in

all three drill holes for these intrusion -related targets, no significant mineralization was encountered. As a result, the

technical team has temporarily suspended drilling on the four remaining platforms in the La Vaquera-Sesmo Sur area while

they conduct additional work to re-evaluate and better understand the favourable geology and mineral potential to

determine the next steps.

Analytical results from the regional exp loration drill holes will be released when they pass internal QAQC procedures.

Figure 2 illustrates the drill locations for the results of the five 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 regional exploration

drilling program in Table 2 at the end of this news release.

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, silv er, copper,

lead, and zinc.
