Adventus Mining Corporation and Salazar Resources Limited announced 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 continues at El Domo with two diamond drill rigs with 19 infill definition drill holes having been successfully completed totaling 1,999 metres from the planned 4,960 metres, and two drill holes in progress totaling a further 21.2 metres completed. In addition, the Partners are pleased to provide an update on 2021 exploration and development plans at their three copper-gold projects in Ecuador – Curipamba (containing El Domo), Pijili and Santiago.

Drill hole CURI-345 intersected well mineralized grainstone with massive sulphide clasts in the hanging wall of the massive sulphide mineralization from 53.52 to 57.40 metres, grading 2.78% copper, 9.65 g/t gold, 3.11% zinc, 110.8 g/t silver, and 0.33% lead (12.48% CuEq). A higher-grade subset was intersected from 54.65 to 56.20 metres, grading 5.92% copper, 21.90 g/t gold, 6.78% zinc, 250.0 g/t silver, and 0.74% lead (27.81% CuEq). Beneath the well mineralized grainstone, two mineralized fine-grained felsic tuffaceous or sediment units were intersected from 66.10 to 68.04 metres and 80.18 to 84.62 metres.

These units graded respectively 2.97% copper, 6.43 g/t gold, 2.07% zinc, 73.5 g/t silver, and 0.40% lead (9.47% CuEq) and 0.32% copper, 1.41 g/t gold, 2.28% zinc, 55.4 g/t silver, and 0.56% lead (2.93% CuEq). Massive sulphide mineralization was intersected from 84.62 to 87.76 metres, grading 2.30% copper, 1.33 g/t gold, 0.72% zinc, 31.8 g/t silver and 0.02% lead (3.91% CuEq). CURI-347 intersected massive sulphide mineralization from 52.90 to 91.00 metres, grading 0.58% copper, 1.04 g/t gold, 0.64% zinc, 25.8 g/t silver, and 0.13% lead (1.90% CuEq).

This interval includes a wide section of syn-mineralization basaltic dyke from 54.00 to 80.54 metres that intruded into the massive sulphide mineralization resulting in mineralized margins from 54.00 to 56.00 metres, grading 2.64% copper, 3.90 g/t gold, 2.57% zinc, 101.1 g/t silver and 0.26% lead (7.65% CuEq). The massive sulphide mineralization was intersected from 52.90 to 54.00 metres, grading 6.13% copper, 4.01 g/t gold, 1.14% zinc, 39.0 g/t silver, and 0.09% lead (10.02% CuEq) and from 80.54 to 91.00 metres, grading 0.94% copper, 2.60 g/t gold, 1.71% zinc, 70.1 g/t silver, and 0.41% lead (4.37% CuEq). A subset of higher-grade massive sulphide occurs near the base of the intercept from 88.50 to 89.60 metres, grading 0.23% copper, 9.30 g/t gold, 6.20% zinc, 363.0 g/t silver and 2.18% lead (13.88% CuEq).

CURI-348 intersected a single mineralized, fine-grained felsic tuffaceous or sediment unit in the hanging wall of the massive sulphide mineralization from 123.96 to 125.58 metres, grading 0.13% copper, 0.98 g/t gold, 0.65% zinc, 27.3 g/t silver, and 0.23% lead (1.45% CuEq). Gold- and silver-rich massive sulphide mineralization was intersected from 125.58 to 128.30 metres, grading 0.95% copper, 8.93 g/t gold, 12.32% zinc, 673.4 g/t silver and 6.64% lead (20.88% CuEq). Stratigraphically beneath the massive sulphide in CURI-348 is a well mineralized felsic autobreccia in the footwall rocks intersected from 128.30 to 135.10 metres, grading 0.66% copper, 0.22 g/t gold, 5.31% zinc, 20.4 g/t silver and 0.19% lead (2.99% CuEq).
