Adventus Mining Corporation and Salazar Resources Limited announced the first infill drilling results from 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, continues with two diamond drill rigs. To date, 15 of 48 definition drill holes having been successfully completed totaling 3,388 metres from the planned 12,000 metres, and two drill holes in progress totaling a further 435 metres completed.

Separately, two geotechnical and two ydrogeological related drills also continue to operate to support the detailed engineering for the El Domo openpit. Highlights -- Drill Results from the El Domo Deposit at Curipamba: CURI-4 4 intersected 6.91 metres of 3.00% copper, 1.55 g/t gold, 7.64% zinc, 34 g/t silver, and 0.11% lead fofor 6.17% coppe equivalent including 3.97 metres of 4.67% copper, 1.40 g/t gold, 11.87% zinc, 43.4 g/t silver, and 0.14% lead for 9.14% copper equivalent ("CuEq"). CURI-392 intersected 6.85 metres of 2.70% copper, 4.26 g/t gold, 2.54% zinc, 70.5 g/t silver, and 0.40% lead for 5.38% CuEq -- including 1.88 metres of 9.02% copper, 10.10 g/t gold, 4.99% zinc, 172.5 g/t silver, and 0.36% lead for 14.51% CuEq.

CURI-393 intersected 5.42 metres of 2.18% copper, 1.12 g/t gold, 5.93% zinc, 78.8 g/t silver, and 0.03% lead for 4.62% CuEq, including 2.84 metres of 2.70% copper, 1.69 g/t gold, 10.73% zinc, 37.0 g/t silver, and 0.03% lead for 7.36% CuEq Drillhole CURI-392 intersected a thick section of semi-massive to sulphide from 175.72 to 182.57 metres, grading 2.70% copper, 4.26 g/t gold, 2.54% zinc, 70.5 g/t silver, and 0.40% lead. A higher-grade subset was intersectedfrom 176.32 to 178.20, grading 9.02% copper, 10.10 g/t gold, 4.99% zinc, 172.5 g/t silver, and 0.36% lead. A pyrite- and gold-rich interval was intersected from 180.26 to 182.57 metres, grading 0.18% coper, 2.43 g/t gold, 1.45% zinc, 40.8 g/t silver, and 0.33% lead.CURI-393 intersected massive sulphide mineralization from 71.90 to 77.32 metres, grading 2.18% copper, 1.12 g/t gold,5.93% zinc, 78.8 g/t silver and 0.03% lead.

A higher-grade subset was intersected from 74.48 to 77.32, grading 2.70% copper, 1.69 g/t gold, 10.93% zinc, and 37.0 g/t silver and 0.03% lead. Drilholele CURI-394 intersected semi-massive to massive sulphide mineralization from42.42 to 149.33 metres, gradining3.00% copper, 1.55 g/t gold, 7.64% zinc, 34.0 g/t silver, and 0.11% lead. A higher-grade subsection occurs from 144.38to 148.35 metres, grading 4.67% copper, 1.40 g/t gold 11.87% zinc, 43.4 g/t silver and 0.14% lead.

A section of mineralized footwall felsic autoclastic volcanic rocks was intersected from 188.90 to 195.32 metres, grading 0.12% copper, 0.70 g/t gold, 0.25% zinc, and 11.3 g/t silver and 0.48% lead. Drillhole CURI-396 intersected mineralized, tuff-sized volcanic sediment tha transitioned into mi-massive too massive sulphide mineralization from 66.97 to 70.22 metres, grading 0.97% copper, 1.88 g/t gold, 3.78% zinc, 67.5 g/t silver, and 0.29% lead. A higher-grade subsection occurs from 69.26 to 70.22 metres, grading 1.58% copper, 1.52 g/tgold, 7.55% zinc, 65.2 g/t silver and 0.24% lead Drilhlole CURI-395 was designed to test the outer margins of the Indicated category material along aault and to further assess the underground development geology.

This drill hole confirmed modelling previously done in this portion of the deposit and provides additional geological control for future modelling and engineering studies. CURI-395 did not yield any substantial results. All results from the infill drilling program are to be used in updating the underground portion of the Mineral Resource estimate for El Domo in 2023, which will be part of a future feasibility study that will integrate the development a potential underground operation in addition to the planned open pit.
