Adventus Mining Corporation ('Adventus') (TSX-V: ADZN, OTCQX: ADVZF) and Salazar Resources Limited ('Salazar') (TSX-V: SRL, OTCQB: SRLZF) (collectively the 'Participants') are pleased to announce 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.

Highlights - Drill Results from the El Domo Deposit at Curipamba: CURI-412 intersected a 14-metre interval of massive sulphide from a depth of 200.27 to 214.46 metres, grading 3.13% copper, 0.79 g/t gold, 4.02% zinc, 27.9 g/t silver for a 4.44% copper equivalent ('CuEq') - including a 1.18 metre interval between 200.27 to 201.45 metres, grading 5.25% copper, 1.3 g/t gold, 2.74% zinc, and 147.2 g/t silver for a 6.69% CuEq

CURI-415 intersected a 5.3-metre interval of massive sulphide from 201.78 to 207.1 metres, grading 3.37% Cu, 1.87 g/t Au, 1.32% Zn, 10.2 g/t silver and 0.01%Pb for a 4.09% CuEq

Drill hole CURI-412 intersected a thick section of massive sulphide from 200.27 to 214.46 metres, grading 3.13% copper, 0.79 g/t gold, 4.02% zinc, 27.9 g/t silver - including a 1.18 metre subset from 200.27 to 201.45 metres with 5.25% copper, 1.31 g/t gold, 2.74% zinc, and 147.2 g/t silver. The highest gold and zinc values are on the upper part of the massive sulphide but the copper values continue down to 214.46 metres.

CURI-416 was designed to test an area with low density of drill holes towards the east of the underground resources. It intersected a low-grade mineralized interval in the footwall but did not yield any substantial results.

CURI-417 tested the eastern boundaries of the inferred resource defined on the El Domo resource DRA 2021. It intercepted the footwall with a hydrothermal breccia with no significant mineralization.

All results from the infill drilling program are to be used in updating the underground portion of the Mineral Resource estimate for El Domo, 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 .

For reference, the last Mineral Resource estimate completed in accordance with NI 43-101 for El Domo was published as part of the Feasibility Study report titled: 'NI 43-101 Technical Report, Feasibility Study, Curipamba El Domo Project, Central Ecuador', with an effective date of October 26, 2021 on SEDAR.
