Adventus and Salazar Announce Drilling Results at The El Domo Deposit Highlighted by 5.06% Copper Equivalent Over 44.19 Metres

TORONTO, March 16, 2021 /CNW/ - Adventus Mining Corporation ("Adventus") (TSXV: ADZN) (OTCQX: ADVZF) and Salazar Resources Limited ("Salazar") (TSXV: SRL) (OTCQB: SRLZF) (collectively the "Partners") are pleased to announce continued infill drilling results from the El Domo volcanogenic massive sulphide deposit located within the 21,537-hectare Curipamba project in central Ecuador. Infill drilling for the ongoing feasibility study continues at El Domo with two diamond drill rigs having completed 42 infill definition drill holes totaling 4,725 metres from the planned 4,960 metres, and two drill holes in progress totaling a further 77 metres completed. The Partners anticipate that all infill, geomechanical, geotechnical, and hydrogeological drilling required to support the completion of the El Domo feasibility study and submittal of the environmental and social impact assessment will be completed by the end of March 2021.

• CURI-356 intersected 10.92 metres of 5.81% copper, 1.58 g/t gold, 3.16% zinc, 34.3 g/t silver and 0.04% lead for 8.09% CuEq – including 3.79 metres of 12.05% copper, 3.67 g/t gold, 8.90% zinc, 67.9 g/t silver, and 0.09% lead for 17.73% CuEq

Drill hole CURI-356 intersected mineralized fine-grained sediments in the immediate hanging wall of the massive sulphide from 65.10 to 69.12 metres, grading 0.37% copper, 0.85 g/t gold, 2.87% zinc, 15.9 g/t silver, and 0.06% lead (1.94% CuEq). Massive sulphide mineralization was intersected from 69.12 to 80.04 metres, grading 5.81% copper, 1.58 g/t gold, 3.16% zinc, 34.3 g/t silver and 0.04% lead (8.09% CuEq). A higher-grade subset occurs from 69.12 to 72.91 metres, grading 12.05% copper, 3.67 g/t gold, 8.90% zinc, 67.9 g/t silver, and 0.09% lead (17.73% CuEq). In the footwall, a section of mineralized dacite autobreccia was intersected from 80.04 to 89.26 metres, grading 0.84% copper, 0.12 g/t gold, 0.16% zinc, 3.4 g/t silver and 0.02% lead (1.00% CuEq). A higher-grade subset was from 85.30 to 89.26 metres, grading 1.81% copper, 0.07 g/t gold, 0.03% zinc, 3.4 g/t silver and 0.01% lead (1.89% CuEq).

CURI-357 intersected a narrow section of well-mineralized grainstone with massive sulphide clasts in the immediate hanging wall of the massive sulphide from 51.26 to 52.34 metres, grading 0.50% copper, 1.74 g/t gold, 2.51% zinc, 71.1 g/t silver, and 0.72% lead (3.16% CuEq). The thick section of massive sulphide mineralization was from 52.34 to 96.53 metres, grading 3.39% copper, 2.30 g/t gold, 0.42% zinc, 13.4 g/t silver, and 0.03% lead (5.06% CuEq). A higher-grade subset of the massive sulphide mineralization was from 69.09 to 92.92 metres, grading 5.96% copper, 2.79 g/t gold, 0.42% zinc, 19.6 g/t silver, and 0.04% lead (7.99% CuEq).

CURI-359 intersected massive sulphide mineralization from 61.70 to 75.60 metres, grading 1.13% copper, 1.50 g/t gold, 2.75% zinc, 43.1 g/t silver, and 0.20% lead (3.35% CuEq). Three narrower subsets of higher-grade massive sulphide mineralization were intersected from 61.70 to 63.50 metres, grading 0.61% copper, 4.27 g/t gold, 13.89% zinc, 256.1 g/t silver, and 1.34% lead (10.22% CuEq); from 67.28 to 73.06 metres, grading 2.41% copper, 1.80 g/t gold, 1.00% zinc, 16.9 g/t silver, and 0.06% lead (3.51% CuEq); and from 69.79 to 71.60 metres, grading 5.97% copper, 3.03 g/t gold, 2.14% zinc, 19.3 g/t silver, and 0.03% lead (8.67% CuEq).

Drill holes CURI-358 and CURI-360 were designed to test the outer margins of the Indicated category material and to further assess the pit wall geology. These drill holes confirmed modelling previously done along the margins of the deposit and provide excellent geological control for future modelling studies. Drill hole CURI-358 intersected mineralization in the footwall felsic autoclastic volcanic rocks from 96.13 to 109.00 metres, grading 0.03% copper, 0.15 g/t gold, 0.52% zinc, 6.7 g/t silver, and 0.02% lead (0.36% CuEq) over 8.37 metres approximate true thickness.  Drill hole CURI-360 intersected mineralized fine-grained sediments from 50.08 to 51.96 metres, grading 0.03% copper, 2.05 g/t gold, 0.41% zinc, 91.5 g/t silver, and 0.19% lead (2.30% CuEq) over 1.50 metres approximate true thickness.

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).

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.

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.
