Adventus Mining Corporation (TSX-V: ADZN) (OTCQX: ADVZF) and Salazar Resources Limited (TSXV: SRL) (OTCQB: SRLZF)  are pleased to announce additional 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 is completed at El Domo for 53 infill definition drill holes totaling 5,348 metres.

CURI-364 intersected mineralized grainstone with massive sulphide clasts in the immediate hanging wall of the massive sulphide from 111.00 to 115.46 metres, grading 1.61% copper, 1.19 g/t gold, 0.85% zinc, 21.7 g/t silver, and 0.13% lead (2.83% CuEq). Massive sulphide mineralization was intersected from 115.46 to 130.40 metres, grading 6.49% copper, 1.64 g/t gold, 1.52% zinc, 35.5 g/t silver, and 0.16% lead (8.34% CuEq). Two subsets of higher-grade massive sulphide mineralization were intersected from 115.46 to 118.24 metres and 124.50 to 130.40 metres.  The first intercept graded 1.63% copper, 1.40 g/t gold, 1.62% zinc, 33.2 g/t silver, and 0.12% lead (3.33% CuEq), and the second intercept graded 14.29% copper, 2.11 g/t gold, 1.95% zinc, 34.3 g/t silver, and 0.16% lead (16.54% CuEq). The drill hole was lost in a fault zone at 130.40 metres while still in mineralization and did not reach targeted completion depth.

CURI-364-A was an attempted re-drill of CURI-364, however, it was also terminated in the same fault zone. It intersected mineralized grainstone in the hanging wall of the massive sulphide mineralization from 109.90 to 113.58 metres, grading 1.71% copper, 1.45 g/t gold, 1.13% zinc, 40.2 g/t silver and 0.09% lead (3.34% CuEq). Massive sulphide mineralization was intersected from 113.58 to 114.75 metres, grading 1.62% copper, 2.78 g/t gold, 10.24% zinc, 235.0 g/t silver and 1.45% lead (9.00% CuEq), but the drill hole re-entered mineralized grainstone from 114.75 to 120.77 metres, grading 1.00% copper, 1.74 g/t gold, 1.48% zinc, 37.7 g/t silver and 0.16% lead (2.91% CuEq). The drill hole was lost in a fault zone at 121.80 metres while still in mineralization and did not reach targeted completion depth.

Drill holes CURI-363 and CURI-365 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-363 intersected a thick section of mineralization in the footwall felsic autoclastic volcanic rocks from 54.54 to 90.95 metres with two intervals providing low-grade intercepts. The first intercept was from 54.54 to 59.68 metres, grading 0.06% copper, 0.19 g/t gold, 0.81% zinc, 12.0 g/t silver, and 0.18% lead (0.57% CuEq) over 3.34 metres approximate true thickness. The second intercept was from 69.62 to 84.89 metres, grading 0.05% copper, 0.02 g/t gold, 0.53% zinc, 0.8 g/t silver and 0.02% lead (0.24% CuEq) over 9.93 metres approximate true thickness.

 

Drill hole CURI-365 also intersected mineralization in the footwall felsic autoclastic volcanic rocks from 39.72 to 51.52 metres, grading 0.03% copper, 1.06 g/t gold, 0.34% zinc, 69.0 g/t silver, and 0.15% lead (1.45% CuEq) over 8.26 metres approximate true thickness. A high-grade subset occurs from 39.72 to 45.56 metres, grading 0.03% copper, 1.61 g/t gold, 0.42% zinc, 119.8 g/t silver, and 0.17% lead (2.29% CuEq) over 4.09 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). Figure 1 illustrates the drill locations for the results of the six 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.

 

Technical Information and Quality Control & Quality Assurance

 

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 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.
