ZINC ONE DRILLING FURTHER EXTENDS HIGH-GRADE ZINC DEPOSIT DISCOVERY AT MINA CHICA ZONE, BONGARA ZINC MINE PROJECT, PERU

Zinc One Resources Inc. has further extended the recently discovered high-grade zinc deposit to the west and northwest in the Mina Chica zone of the Bongara zinc mine project, located in north-central Peru. The discovered deposit has been delineated to the northwest and is at least 150 metres long in a northwest-southeast direction (open to the southeast) and, at the northwest end, is at least 80 metres wide (open to the west). The current drill program for Mina Chica has now been completed with the final data from sampling still pending.

Jim Walchuck, president and chief executive officer of Zinc One, commented: "The results from the Mina Chica zone continue to impress, and it has become apparent that Mina Chica will be an important part of the overall growth of the Bongara project. We will have enough information from this drilling to estimate a resource even though the discovery deposit is open in several directions."

Mina Chica drill results highlights:

• Fifty-three drill holes for 2,370.9 metres have been drilled from 18 platforms:
  • Results from 26 holes were reported previously (see news releases from April 9, April 26 and May 1, 2018).
• Significant new intercepts include:
  • MCH18027: 14.8 metres of 28.4 per cent zinc, from surface;
  • MCH18035: 39.0 metres of 27.4 per cent zinc, from 23.8-metre drill depth:
    • True vertical thickness of 27.6 metres from a true vertical depth of 16.8 metres;
    • Intercept is open to the west.
• MCH18031 and MCH18032 delimit the deposit in the northwest, near which MCH18030 delimits the deposit to the northeast.
• Mineralization at Mina Chica includes zinc oxides, carbonates and silicates hosted by soils, highly weathered carbonates and fine- to coarse-grained dolomites.

Mina Chica is one of three known zones of high-grade, near-surface zinc-oxide mineralization along a 1.4-kilometre mineralized trend that is being tested by this drill program. At Bongarita, which lies approximately 200 metres west of Mina Chica, all results from the 36 holes (587.2 metres) drilled have been reported. At Mina Grande Sur, which lies approximately 1.2 kilometres southeast of Mina Chica, results from 24 of 95 holes drilled, for a total of 2,328.4 metres, have been reported. This program was recently completed, and the drill rig is now drilling at Mina Grande Centro.

Geology and discussion of results

The zinc mineralization at Bongara is hosted by carbonate rocks and is classified as a Mississippi Valley-type deposit. The mineralization is stratabound and is basically a tabular body with irregular boundaries. Hydrozincite, smithsonite, hemimorphite and a zinc-aluminum-iron silicate are the primary zinc minerals that are hosted primarily by soils, heavily weathered fractured and vuggy dolomites and fine- to coarse-grained dolomites.

Significant results, including drill hole orientation and total depths for Mina Chica, can be found below in the attached table.

Sampling and analytical protocols

Zinc One follows a systematic and rigorous quality control/quality assurance program overseen by Dr. Bill Williams, chief operating officer and director of Zinc One.

The sample from each core run is placed in a 60-centimetre-long plastic core box that has five columns. Core recovery, rock quality designation (RQD) and geologic features are logged, and sample intervals, which are generally fewer than two metres, are chosen. Each core box is photographed and then sampled with a spatula (soil and heavily weathered rock) or cut with a core saw, 50 per cent of which is placed in a sample bag and stored on site in a secure location. The company independently inserts certified control standards, blanks and duplicates, all of which comprise at least 20 per cent of the sample batch, to monitor sample preparation and analytical quality. The samples are stored in a secure area until such time as they are shipped to the ALS or Certimin laboratories in Lima, both of which are ISO 9001 certified, for preparation and assay. At the laboratory, samples are dried, crushed and pulverized, and then a four-acid digestion is applied. This is followed by the ICP-AES analytical technique for up to 37 elements, including lead. The same method is used to assay zinc for values up to 20 per cent. If zinc exceeds 20 per cent, it is then analyzed using a titration method. The laboratories also insert blanks and standards, as well as including duplicate analyses.
