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 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.

Update on 2021 Copper-Gold Exploration & Development Plans in Ecuador

As Adventus and Salazar continue its close and successful partnership now in its fourth year, the Partners are excited and expect 2021 to include significant milestones for the development of the El Domo copper-gold deposit into a future mine as well as the potential for major new discovery through greenfield exploration at the Partners’ three projects in Ecuador. The Partners are in a strong financial position and expect 2021 development and exploration spending to total approximately US$20 million – highlighted by the completion of the El Domo copper-gold feasibility study, as well as exploration related activities at the greater Curipamba project and the Pijili and Santiago projects. Below is a summary of key 2021 activities expected for each project:

  • At El Domo, infill and step-out drilling program to continue and be completed during the first quarter, with continuous drill assay results into the second quarter
  • Greenfield exploration of the 15 regional targets identified by the Partners’ detailed target generation initiative (see December 21, 2020 news release) is expected to continue throughout 2021. One drill rig is currently drilling at the La Vaquera target, approximately 8 km southwest of El Domo, and is expected to relocate to other targets this year
  • The draft environmental and social impact assessment on El Domo is underway and expected to be submitted to the government of Ecuador in the third quarter. This will involve community consultation sessions and the results of the ongoing environmental monitoring and testing which are being conducted by the Partners and experienced consultants to international best practice standards
  • The El Domo feasibility study underway is expected to be completed in the second half of 2021 and published in the fourth quarter (see December 2, 2020 news release)
  • During 2021, the Partners will be negotiating an investment and exploitation agreement with the government of Ecuador to provide the framework for the construction of El Domo from 2022 to 2023. This is an established and transparent process that facilitated the recent financing and construction of both the Mirador and Fruta del Norte mines in Ecuador
  • Adventus has already begun discussions with multiple interested parties with project financing options to fund the development of El Domo
  • One drill rig is currently completing the maiden drill program at the Mercy concession – one of three concessions that constitute the Pijili project. Drilling for this current program is expected to be completed during the first quarter, with drill assay results to be released when confirmed
  • Regional prospecting continues on several targets within the Mercy concession as well as the other two concessions located approximately 10 km west of Mercy
  • Community support, including public health initiatives related to the current pandemic, and socialization of the Partners’ exploration plans for the project are continuing at site
  • The Partners expect to mobilize and commence drilling during the second or third quarter for a minimum 2,500 metre initial drill program
Over 2021, the Partners will provide an update on exploration progress at their three projects on a timely basis. In addition to the three projects, the Partners are currently evaluating several other early-stage porphyry projects in Ecuador to potentially acquire into their country-wide exploration alliance.

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.
