Adventus Zinc Corporation (TSX-V: ADZN) (OTCQX: ADVZF) and Salazar Resources Limited (TSX-V: SRL) are pleased to announce additional drill holes from the 2018 infill drilling program on the El Domo volcanogenic massive sulphide deposit; which is part of the approximately 22,000-hectare Curipamba project located near Las Naves, Ecuador.

• CURI-301 intersected 17.23 metres of 3.75% copper, 3.12 g/t gold, 3.32% zinc, 48.5 g/t silver, and 0.21% lead for 7.75% CuEq.

El Domo Infill Drilling Results

The first phase of infill drilling commenced in early March 2018 with the objective of upgrading the confidence level of the higher-grade portion of the open-pit constrained Mineral Resource by decreasing drill spacing. The Partners have now completed the first phase of infill drilling within the higher-grade portion of the open-pit constrained Mineral Resource with 8,587 metres drilled.  An optimized Phase 2 infill drilling program is now in progress for the remainder of the open-pit constrained Mineral Resource; which is anticipated to be completed in late fourth quarter of 2018.

Drill hole CURI-300 intersected a gold-rich zone of fault-entrained massive sulphide mineralization from 64.35 to 69.00 metres for an approximate true thickness of 1.48 metres grading 1.74% copper, 10.93 g/t gold, 13.60% zinc, 393.5 g/t silver, and 2.03% lead.  Massive sulphide mineralization was then intersected from 69.00 to 90.10 metres for an approximate true thickness of 17.94 metres, grading 5.49% copper, 3.94 g/t gold, 2.77% zinc, 42.3 g/t silver, and 0.19% lead. A subset interval of massive sulphide mineralization contains significantly higher-grade from 69.00 to 77.70 metres, grading 11.31% copper, 7.81 g/t gold, 6.57% zinc, 90.9 g/t silver, and 0.44% lead.

Drill hole CURI-301 intersected massive to semi-massive sulphide mineralization occurs from 47.41 to 64.64 metres for a true thickness of 15.51 metres, grading 3.75% copper, 3.12 g/t gold, 3.32% zinc, 48.5 g/t silver, and 0.21% lead.  A subset interval of massive sulphide mineralization possesses significantly higher-grade from 47.41 to 50.12 metres, grading 9.21% copper, 11.91 g/t gold, 17.69% zinc, 220.6 g/t silver, and 1.21% lead.

CURI-302 intersected a fault-entrained portion of massive sulphide from 71.47 to 74.57 metres for a true thickness of 2.95 metres, grading 0.50% copper, 3.39 g/t gold, 8.02% zinc, 82.0 g/t silver, and 0.96% lead at the at between the hanging wall lapilli resedimented volcaniclastic rocks and footwall dacite autobreccia volcaniclastic rocks.  A subset of the faulted massive sulphide had higher grades from 72.60 to 73.74 metres, grading 0.48% copper, 6.96 g/t gold, 18.65% zinc, 175.5 g/t silver, and 2.44% lead. 

In CURI-303, a section of low-grade stockwork in the footwall dacite volcaniclastic rocks was intersected from 50.42 to 101.07 metres for a true thickness of 45.59 metres, grading 0.06% copper, 0.15 g/t gold, 0.76% zinc, 6.6 g/t silver, and 0.03% lead.  A subset possessed slightly higher grades from 50.42 to 72.00 metres, grading 0.09% copper, 0.20 g/t gold, 1.16% zinc, 11.2 g/t silver, and 0.05% lead. 

Drill hole CURI-298, CURI-304, and CURI-305 intersected gold-rich grainstone above a highly pyritic, lower-grade massive sulphide unit.  CURI-306 did not intersect mineralized grainstone, however, did have massive sulphide and semi-massive sulphide units separated by a zone of intense gypsum hydrothermal alteration.  Results for these drill holes is tabulated below. 

Drill holes CURI-299 was designed to test the westerly limits of the known massive sulphide mineralization and further assess the pit wall geology, and if there was low-grade stockwork below favourable strata. These drill holes all intersected favourable strata; however, no semi-massive to massive sulphide mineralization was intersected.

The locations of all drill holes referenced in this press release are shown on the Curipamba Project drill plan map, which is available on the Adventus website.

Technical Information and Quality Control & Quality Assurance

The Curipamba project work program is being managed and reviewed by Vice President Exploration, Jason Dunning, M.Sc., P.Geo., a Qualified Person within the meaning of NI 43-101. Salazar staff collect and process samples that are securely sealed and shipped to Bureau Veritas (“BV”) in Quito for sample preparation that includes crushing and milling to prepare pulps that are then split for shipment to their facility in Lima, Peru for analysis. All assay data have undergone internal validation of QAQC; noting there is an established sampling control program with blind insertion of assay blanks, certified industry standards and sample duplicates for the Curipamba project. A QAQC program is also in place at BV and includes insertion of blanks, standards and duplicate reanalysis of selected samples.  BV’s quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. At BV, gold is analyzed by classical fire assay techniques with an ICP-AES finish, and both silver and base metals are analyzed by a 44-element aqua regia ICP-AES technique. Overlimit protocols are in place for gold, silver, copper, lead, and zinc.

Infill drilling continues to yield intercepts of high-grade, copper- and gold-rich semi-massive to massive sulphide mineralization within the open-pit constrained Mineral Resource update for the El Domo VMS deposit completed by Roscoe Postle Associates Inc. The Indicated Mineral Resource totals 8.8 million tonnes grading 1.62% copper, 2.34 g/t gold, 2.42% zinc, 48.0 g/t silver, and 0.27% lead. The Inferred Mineral Resource totals 2.6 million tonnes grading 1.29% copper, 1.09 g/t gold, 1.51% zinc, 29.0 g/t silver, and 0.14% lead (see January 31, 2018news release). The National Instrument (“NI”) 43-101 Technical Report was authored by Independent Qualified Person Dr. Lars Weiershäuser, P.Geo., of RPA (based in Toronto, Ontario, Canada) who is a Qualified Person as defined by NI 43-101.
