Adventus Mining Corporation announced the additional infill drilling results from the underground portion of the El Domo volcanogenic massive sulphide deposit (‘El Domo') located within the 21,537-hectare Curipamba project in central Ecuador. The infill drilling program for the underground portion of the Mineral Resource at El Domo, as announced in the August 29, 2022 news release, continues with two diamond drill rigs. Drill hole CURI-401 intersected a thick section of lower-grade semi-massive sulphide intercalated with gypsum alteration from 171.54 to 187.82 metres with a narrower section from 171.54 to 173.90 metres, grading 1.17% copper, 0.62 g/t gold, 0.39% zinc, 21.5 g/t silver, and 0.11% lead.

A higher-grade subset was intersected from 171.54 to 172.20, grading 3.39% copper, 0.69 g/t gold, 1.27% zinc, 65.1 g/t silver, and 0.37% lead. CURI-402 intersected semi-massive to massive sulphide mineralization from 201.57 to 206.31 metres, grading 2.84% copper, 0.75 g/t gold, 0.06% zinc, 7.8 g/t silver and 0.01% lead. A higher-grade subset was intersected from 203.11 to 204.24 metres, grading 10.25% copper, 1.47 g/t gold, 0.14% zinc, and 24.8 g/t silver and 0.01% lead.

Drill hole CURI-403 intersected semi-massive to massive sulphide mineralization with intercalated felsic autobreccia at the base of the intercept, from 237.10 to 244.73 metres, grading 0.87% copper, 3.91 g/t gold, 3.09% zinc, 40.7 g/t silver, and 0.50% lead. A higher-grade subsection occurs from 237.10 to 240.10 metres, grading 0.83% copper, 9.18 g/t gold, 5.67% zinc, 76.0 g/t silver and 1.13% lead. Drill hole CURI-404 intersected semi-massive sulphide mineralization from 245.15 to 250.03 metres, grading 2.29% copper, 0.88 g/t gold, 0.99% zinc, 50.4 g/t silver, and 0.09% lead.

A higher-grade subsection occurs from 249.13 to 250.03 metres, grading 3.93% copper, 2.25 g/t gold, 1.24% zinc, 103.9 g/t silver and 0.23% lead. Drill hole CURI-405 intersected semi-massive sulphide mineralization with intercalated felsic autobreccia from 205.42 to 208.33 metres, grading 1.85% copper, 2.03 g/t gold, 0.51% zinc, 10.1 g/t silver, and 0.01% lead. A thick section of semi-massive to massive sulphide mineralization occurs from 214.06 to 223.52 metres, grading 7.49% copper, 2.37 g/t gold, 2.93% zinc, 75.4 g/t silver and 0.01% lead.

A higher-grade section occurs from 214.06 to 219.33 metres, grading 12.08% copper, 4.00 g/t gold, 5.24% zinc, 131.1 g/t silver, and 0.02% lead.
