All results from the infill drilling program are to be used in updating the underground portion of the Mineral Resource estimate for El Domo in 2023, which will be part of a future feasibility study that will integrate the development of a potential underground operation in addition to the planned open pit (see August 29, 2022 news release). Figure 1 illustrates the drill locations for the results of the five drill holes outlined in this news release. Drill collar location coordinates are summarized for the infill drilling program 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 Feasibility Study report titled: “NI 43-101 Technical Report, Feasibility Study, Curipamba El Domo Project, Central Ecuador“, with an effective date of October 26, 2021 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 in Quito for sample preparation that includes crushing and milling to prepare pulps that are then split for shipment to their facility in 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 regional drilling have silver and base metals analyzed by a modified ore grade 24-element aqua regia technique with ICP-ES finish. Gold is analyzed by fire assay fusion with AAS finish. Overlimit protocols are in place for gold, silver, copper, lead, and zinc.
