2.4 Metres of 38.1% Zinc Hosted by Soils at Bongarita
Vancouver, BC - April 11, 2018 - Zinc One Resources Inc. (TSX-V: Z; OTC Markets: ZZZOF; Frankfurt: RH33 - “Zinc One” or the “Company”) announces the final drill results from the Bongarita mineralized zone subsequent to the results previously reported (see news release from March 29, 2018). The Bongarita zone is one of several high-grade mineralized areas being targeted in the ongoing drill program at the Company’s Bongará Zinc Mine project located in north-central Peru. A total of 36 holes for 582.7 metres were drilled at Bongarita. Very fine-grained zinc mineralization, mostly as silicates exclusively hosted by soils, has been delineated over an area of approximately 7,500 square metres.
Bongarita is only one of the three known zones, which includes Mina Chica and Mina Grande Sur, of high-grade, near-surface, zinc-oxide mineralization along a 1.6 kilometre mineralized trend that is being tested. Two portable rigs continue to drill at Mina Chica and Mina Grande Sur. At Mina Chica, which lies approximately 200 metres east of Bongarita, results from 6 of the 41 holes drilled have been reported. At Mina Grande Sur, which is approximately 1.2 kilometres southeast of Bongarita, results from 11 of 60 holes drilled there have been reported at this time. Results reported to date are from zinc oxides, carbonates, and silicates hosted by soils, highly-weathered carbonates, and dolomites in those areas.
Bongarita Drill Results Highlights:
- Significant intercepts include:
- BO18022 - 2.4 metres of 38.1% zinc, from 1.5 metres drill depth
- BO18033 - 2.4 metres of 42.8% zinc, from 7.9 metres drill depth
- True thickness of 1.7 metres starting at 5.6 metres true drill depth
- MCH18006 - 5.8 metres of 19.1% zinc from the surface
- True thickness of 4.1 metres to true drill depth of 4.1 metres
- MCH18006 - 5.8 metres of 19.1% zinc from the surface
- A total of 36 holes totaling 582.7 metres were drilled from 12 platforms
- Zinc mineralization, mostly in silicates, has been delineated within an area of approximately 7,500 square metres
- All zinc mineralization is hosted by soils
- The zinc mineralization is nearly delineated- it is open eastward in the NE sector where BO18033 and BO18036 had 1-2 metre intercepts of >30% zinc.
Jim Walchuck, President and CEO of Zinc One commented, “The drilling at Bongarita essentially confirmed that the amount of mineralized soils should be similar in size and grade to the historical resource. Zinc One anticipates that this drill data along with the previous pit and channel sampling data, will provide enough data to contribute to the delineation of a resource. The high-grade soils found at Bongarita would require very little stripping and blasting and could possibly be included in the operational startup depending on the outcome of the upcoming resource estimate.”

In addition, a map (see Figure 1.) shows the area of mineralization and the drill hole program at Bongarita. A link to additional maps outlining a more detailed and technical view of the area is also provided.

Geology and Discussion of Results
The zinc mineralization at Bongará 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 by soils, heavily-weathered fractured and vuggy dolomites, and fine- to coarse-grained dolomites. At Bongarita, zinc silicates dominate and they are hosted exclusively by soils.
Sampling and Analytical Protocols
Zinc One follows a systematic and rigorous Quality Control/Quality Assurance program overseen by Dr. Bill Williams, COO 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 <2 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% 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% of the sample batch, to monitor sample preparation and analytical quality. The samples are stored in a secure area until such time they are shipped to ALS laboratory in Lima (ISO 9001 Certified) for preparation and assay. At the laboratory, samples are dried, crushed, pulverized and then a four-acid digestion is applied. This is followed by the ICP-AES analytical technique for 33 elements, including lead. The same method is used to assay zinc for values up to 20%. If zinc exceeds 20%, it is then analyzed using a titration method. The laboratory also inserts blanks and standards as well as including duplicate analyses.

About Zinc One Resources Inc.
Zinc One is focused on the exploration and development of prospective and advanced zinc projects in mining-friendly jurisdictions. The Company’s key assets are the Bongará Zinc Mine Project and the Charlotte Bongará Zinc Project in north-central Peru. The Bongará Zinc Mine Project was in production from 2007 to 2008, but was closed due to the global financial crisis and concurrent decrease in the zinc price. Past production included >20% zinc grades and recoveries over 90% from surface and near-surface zinc-oxide mineralization. High-grade, zinc-oxide mineralization is known to outcrop between the mined area and the Charlotte Bongará Project, which is nearly six kilometres to the NNW and where past drilling intercepted various near-surface zones with high-grade zinc. Zinc One is managed by a proven team of geologists and engineers who have previously constructed and operated successful mining operations.
