ADVENTUS AND SALAZAR SECURE KEY LANDS FOR EL DOMO DEVELOPMENT AND

ANNOUNCE RAMP-UP OF DRILLING WITH THREE RIGS AT CURIPAMBA

Toronto, March 5, 2020 – Adventus Mining Corporation (“Adventus”) (TSX -V: ADZN; OTCQX: ADVZF) and

Salazar Resources Limited ("Salazar") (TSX -V: SRL) (collectively the "Partners") are pleased to announce the

signing of multiple agreements with private individuals to acquire surface rights covering the El Domo

volcanogenic massive sulphide deposit (“El Domo”) within the 21,537-hectare Curipamba project

(“Curipamba”). The acquired surface rights cover 100% of the land overlaying the Mineral Resources and

proposed open pit and underground mines as outlined in the 2019 Preliminary Economic Assessment (the

“PEA”). The Partners have developed a surface rights acquisition plan for the remaining project layout as

outlined in the PEA, subject to the completion of the geotechnical work required to support the milling, tailings

and waste rock facilities. All surface rights required to construct El Domo and the associated facilities are

expected to be acquired by calendar year-end 2021.

One diamond drill rig is currently operating focused on exploration drilling at Curipamba. Over the next three to

four months, the rig will be focused on stepping out to the east of El Domo where the volcanic massive sulphide

mineralization and favourable strata have not been cut-off (3 to 5 holes) and approximately 3,000 metres at the

previously undrilled La Vaquera target in the southern area of Curipamba. This exploration drilling is part of the

previously announced minimum 10,000-metre 2020 diamond drilling program at Curipamba. A second drill rig

focused on regional exploration at Curipamba will mobilize later in the year. All water permits required for

drilling at Curipamba have been successfully renewed with government authorities for 10 years.

Two geotechnical drill rigs have been contracted to start work in the first half of March 2020. They will focus on

the groundwater monitoring wells required for the ongoing environmental impact assessment baseline and

engineering studies on the tailings and waste rock storage facilities as part of the upcoming feasibility study for

El Domo . This drilling is part of the previously announced 3,000- metre minimum engineering related 2020

drilling program for El Domo development.

The published NI 43 -101 Technical Report summarizing the results of the PEA is available on SEDAR with an

effective date of June 14, 2019.
