TORONTO - Adventus Mining Corporation ('Adventus Mining') (TSXV: ADZN) (OTCQX: ADVZF) and Salazar Resources Limited ('Salazar') (TSXV: SRL) (OTCQB: SRLZF) (collectively the 'Participants') are pleased to announce 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, as announced in the August 29, 2022 press release, 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 hydrogeological related drills also continue to operate to support the detailed engineering for the El Domo open pit.

Highlights - Drill Results from the El Domo Deposit at Curipamba:

CURI-394 intersected 6.91 metres of 3.00% copper, 1.55 g/t gold, 7.64% zinc, 34.0 g/t silver, and 0.11% lead for 6.17% copper 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

Drill hole CURI-392 intersected a thick section of semi-massive to massive 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 intersected from 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.

Drill hole CURI-395 was designed to test the outer margins of the Indicated category material along a fault 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 (see August 29, 2022 news release). Figure 1 illustrates the drill locations for the results of the five drill holes outlined in this news release. 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 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.

Update on Agua Santa Target

2021 regional drilling on the Agua Santa target, located 4.5 kilometres to the southwest of El Domo, successfully completed a total of 2,818 metres in 11 drill holes (CREG-008 to CREG-018) in the Agua Santa target area. VMS mineralization was identified in several of the drill holes targeting a Mobile MT ('MMT') airborne geophysical anomaly that coincided with both favourable geology and surface geochemistry results from prospecting in nearby creek beds. The Agua Santa target area remains one of the most prospective volcanic environments outside of El Domo for identifying new VMS occurrences, given that the first drill hole at Agua Santa, CREG-008, intersected three separate intervals of semi-massive sulphide to massive sulphide mineralization from 60.52 to 66.86 metres, grading 1.77% copper, 1.46 g/t gold, 7.45% zinc, 23.2 g/t silver and 0.24% lead. The mineralization is hosted within variably mineralized volcaniclastic rocks, noting the highly fragmental appearance of the mineralization suggests it has been reworked from a potential collapse of the massive sulphide lens downslope. CREG-008 also had in the footwall several broad zones of pyritic stringer stockwork in massive mafic volcanic rocks were observed with focused hydrothermal alteration halos directly around the mineralization (see October 18, 2021 news release).

Drill hole CREG-009 intersected two zones of disseminated to semi-massive sulphide from 28.86 to 32.00 metres, and from 69.47 to 75.20 metres with only the second interval having any results from 72.27 to 75.20 metres, grading 0.25% copper, 0.13 g/t gold, and 0.7 g/t silver. Further down in the footwall there were three separate intervals of low-grade pyritic stockwork. The first interval is from 133.72 to 138.00 metres, grading 0.96% copper, 0.17 g/t gold and 1.0 g/t silver. The second interval is from 152.72 to 154.81 metres, grading 0.55% copper, 0.04 g/t gold and 0.3 g/t silver. The final interval is from 170.18 to 171.26 metres, grading 1.16% copper, 0.05 g/t gold, and 1.4 g/t silver. None of the low-grade stockwork occurrences had appreciable zinc or lead mineralization.

CREG-010 intersected a wide, low-grade zone of heavily disseminated to semi-massive sulphide mineralization from 41.00 to 52.04 metres. Mineralization yielding metal values occurs from 44.50 to 50.57 metres, grading 0.15% copper, 0.31 g/t gold, 0.37% zinc, and 1.7 g/t silver. A higher-grade subset in the semi-massive sulphide mineralization was intersected from 44.50 to 45.12 metres 0.88% copper, 1.32 g/t gold, 2.26% zinc, 14.8 g/t silver and 0.01% lead.
