Adventus Zinc Corporation and Salazar Resources Limited announced 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-311 intersected 8.74 metres of 2.78% copper, 1.93 g/t gold, 3.49% zinc, 54.9 g/t silver, and 0.42% lead for 6.18% CuEq; CURI-312 intersected 12.55 metres of 4.00% copper, 2.04 g/t gold, 0.96% zinc, 25.8 g/t silver, and 0.07% lead for 6.04% CuEq; including 3.60 metres of 10.40% copper, 3.77 g/t gold, 2.97% zinc, 72.9 g/t silver and 0.20% lead for 14.95% CuEq, and; CURI-320 intersected 10.86 metres of 1.50% copper, 2.95 g/t gold, 2.49% zinc, 79.2 g/t silver, and 0.30% lead for 5.40% CuEq; including 2.72 metres of 2.51% copper, 8.50 g/t gold, 8.16% zinc, 250.6 g/t silver and 0.93% lead for 14.40% CuEq. The optimized Phase 2 infill drilling program was completed in late December 2018 on the open-pit constrained Mineral Resource.

A total of 12,608 metres of infill drilling was successfully completed at El Domo in 2018 between both phases of infill drilling on the open-pit constrained Mineral Resource. Additional drilling results will be released once assay results have passed through internal QAQC validation. The Partners will also provide an update to the market with regards to the 2019 Curipamba work plan in the near future.

A subset interval of the grainstone was significantly higher grade from 130.83 to 133.45 metres grading 0.31% copper, 3.06 g/t gold, 3.46% zinc, 509.2 g/t silver, and 1.60% lead. Under the grainstone is copper-rich massive sulphide mineralization from 145.65 to 158.20 metres for a true thickness of 11.92 metres, grading 4.00% copper, 2.04 g/t gold, 0.96% zinc, 25.8 g/t silver, and 0.07% lead.

A subset interval of massive sulphide mineralization possesses significantly higher-grade from 145.65 to 149.25 metres, grading 10.40% copper, 3.77 g/t gold, 2.97% zinc, 72.9 g/t silver, and 0.20% lead CURI-315 intersected massive sulphide from 101.38 to 117.13 metres for a true thickness of 13.39 metres, grading 1.73% copper, 0.76 g/t gold, 0.38% zinc, 12.6 g/t silver, and 0.03% lead. A subset of massive sulphide had higher grades from 101.38 to 103.33 metres, grading 10.37% copper, 2.00 g/t gold, 1.53% zinc, 58.1 g/t silver, and 0.06% lead. Drill hole CURI-316 intersected a narrow section of well mineralized grainstone from 104.20 to 110.48 metres for an apparent true thickness of 5.34 metres grading 2.18% copper, 1.33 g/t gold, 2.42% zinc, 40.1 g/t silver and 0.20% lead.

Under the grainstone is copper-rich semi-massive sulphide mineralization cut by several fault zones from 110.48 to 130.62 metres for a true thickness of 17.12 metres, grading 2.10% copper, 0.68 g/t gold, 0.77% zinc, 13.9 g/t silver, and 0.06% lead. A subset interval of massive sulphide mineralization possesses significantly higher-grade from 110.48 to 112.64 metres, grading 3.51% copper, 1.05 g/t gold, 2.53% zinc, 40.5 g/t silver, and 0.22% lead. Drill hole CURI-318 intersected a narrow section of well mineralized grainstone from 93.11 to 98.90 metres for an apparent true thickness of 4.87 metres grading 3.21% copper, 2.14 g/t gold, 0.49% zinc, 26.3 g/t silver and 0.05% lead.

A subset interval within the grainstone was logged as semi-massive sulphide and it possessed higher grade from 93.91 to 96.14 metres, grading 7.19% copper, 3.37 g/t gold, 0.89% zinc, 32.6 g/t silver and 0.08% lead. The drill hole then intersected pyrite-rich massive sulphide mineralization from 106.23 to 116.06 metres for a true thickness of 9.33 metres, grading 0.19% copper, 0.68 g/t gold, 0.05% zinc, 6.0 g/t silver, and 0.01% lead. CURI-320 intersected a massive to semi-massive sulphide unit from 101.00 to 111.86 metres for a true thickness of 9.34 metres, grading 1.50% copper, 2.95 g/t gold, 2.49% zinc, 79.2 g/t silver, and 0.30% lead.

A subset of the interval had higher grades from 106.18 to 108.90 metres, grading 2.51% copper, 8.50 g/t gold, 8.16% zinc, 250.6 g/t silver, and 0.93% lead Drill hole CURI-309, CURI-314, and CURI-319 intersected gold-rich, highly pyritic, lower-grade massive sulphide unit. In CURI-310, a basalt intrusion appears to have locally digested the VMS mineralization. Results for these drill holes are tabulated below.

Drill holes CURI-322 and CURI-323 were designed to test the westerly limits of the known massive sulphide mineralization and further assess the pit wall geology. These drill holes all intersected favourable strata; however, no semi-massive to massive sulphide mineralization was intersected.
