Vancouver, B.C., March 20, 2019 – Zinc One Resources Inc. (TSX-V: Z; OTC Markets: ZZZOF; Frankfurt: RH33 – “Zinc One” or the “Company”) announces that it has filed on SEDAR the National Instrument (“NI”) 43-101-compliant Technical Report for the Resource Estimate at the Bongará Zinc Mine project in north-central Peru. The estimate was prepared for the Company by Watts Griffis and McOuat Limited (“WGM”).

On February 5, 2019, the Company reported an Indicated Mineral Resource of 812,000 tonnes averaging 18.9% Zn containing 339,000,000 pounds of Zn at a 10% Zn cut-off and an Inferred Mineral Resource of 1,339,000 tonnes averaging 16.8% Zn containing 496,000,000 pounds of Zn at a 10% Zn cut-off. Since then, modeling on the Bongarita zinc-oxide deposit, which is hosted by soils, has added 10,000 tonnes of 13.8% containing 3,000,000 pounds of Zn as Indicated Mineral Resource and 700 tonnes of 12.7% Zn for 200,000 pounds of contained Zn as Inferred Mineral resource.

Notes for Table 1 & 2

1. The Mineral Resource Estimates in this disclosure were completed by Watts, Griffis and McOuat Limited (“WGM”), an independent firm of geological and mining consultants.
2. The effective date of this mineral resource estimate is February 28 2019 and includes all sampling results from drilling and test pitting to the end of 2018.
3. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability but are required to have reasonable prospects for eventual economic extraction. The quantity and grade of reported Inferred Mineral Resources in this estimation are less certain in nature because the amount of exploration has been insufficient to provide the level of confidence necessary to classify them as an Indicated or Measured Mineral Resource. It is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.
4. The Mineral Resource estimates in this news release were estimated using current Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) standards, definitions and guidelines in accordance with Industry Best Practices.
5. Mineral Resources were estimated using a cut-off grade of 10% Zn.
6. Numbers may not add due to rounding. The Mineral Resource estimate was calculated using ordinary kriging methodology. A block model was constructed with block dimensions of 5 x 5 x 5 meters. Zn assays were capped at 40% Zn.
7. A total of 748 drillholes and pits totalling 10,498 m were in the database used for estimation. Only diamond drill holes were used for estimating Indicated Resources; diamond drill holes and pits were used for estimating Inferred Resources. The drill holes were drilled at various orientations. Drillhole spacing is approximately 25 to 30m in areas where resources are estimated. Details of the drill campaign are set out in various news releases from March 29, 2018 to November 15, 2018.
8. A bulk density of 1.90 was applied using the geological block model density field.

The Bongará Zinc Mine project contains an 8-kilometre trend with known near-surface, high grade zinc mineralization. Very little systematic exploration has been completed along this trend, except for drilling at the Cristal Project (northwest end of the trend) that identified a body of high-grade zinc mineralization. This provides an exciting opportunity to discover zinc-rich deposits in future exploration campaigns.

The zinc mineralization at the Bongará Zinc Mine project is classified as a Mississippi Valley-type (“MVT”) deposit and is mostly hosted by strongly dolomitized brecciated limestones beds. The mineralization can also occur as tabular bodies with irregular boundaries, which is a characteristic of that mineralization encountered along the periphery of breccias, especially at Mina Chica. The original MVT sulphide mineralization has been oxidized and now occurs as hydrozincite (zinc-oxide mineral), smithsonite (zinc-carbonate mineral), hemimorphite (zinc-silicate mineral), and zinc-aluminum-iron silicates.

The former Bongará Mine operated during 2007-08, successfully producing zinc from this type of mineralization using a Waelz kiln for processing. The kiln does not require copious amounts of water and an electrical grid, and the waste product is slag that can be used as road material, among other things, thus precluding a permanent tailings storage facility and minimizing initial and sustaining capital outlays.

About Zinc One Resources Inc.

Zinc One’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 the 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 and Cristal Project areas, which are over six kilometres to the north-northwest and where past drilling also intercepted various near-surface zones with high-grade zinc as well.
