Zinc One Resources Inc. (TSX-V: Z) (OTC Markets: ZZZOF) (Frankfurt: RH33) is pleased to announce the results from 29 of the 64 holes drilled in the Mina Grande Centro zone, Bongará Zinc Mine project located in north-central Peru. Noteworthy intercepts include 31.8 metres of 28.2% zinc from MGC18012 and 18.0 metres of 26.2% zinc from MGC18023. These holes tested an area of 125 metres by 50 metres along the northeastern edge of a zone previously mined and subsequently remediated. These holes demonstrated that the near-surface zinc mineralization is open to the northeast, as was indicated by historic drilling and exploration pits.
Jim Walchuck, President and CEO of Zinc One commented, “The Mina Grande Centro drill program successfully confirmed the near-surface zinc mineralization that was left behind by previous mining activity and clearly showed that additional high-grade mineralization has yet to be delineated to the northeast. Along with the zinc-oxide deposits at Mina Chica and Mina Grande Sur, we expect Mina Grande Centro to contribute to the overall resource estimate for the project anticipated to be completed during Q4 2018.”
Mina Grande Centro Drill Results Highlights:
Mina Grande Centro is a part of the Mina Grande zone, one of the three zones of high-grade, near-surface zinc-oxide mineralization along a 1.4 kilometre mineralized trend that was tested by this drill program consisting of 264 holes for 7,930 metres. Drill results at Mina Grande Norte and the remaining drill holes at Mina Grande Centro will be released in the coming weeks.
Geology and Discussion of Results
The zinc mineralization at the Bongará Zinc Mine project is classified as a Mississippi Valley-type deposit and is mostly hosted by strongly dolomitized brecciated limestones that are stratabound. 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. Hydrozincite (zinc oxide mineral), smithsonite (zinc carbonate mineral), hemimorphite (zinc silicate mineral), and a zinc-aluminum-iron silicate are the primary zinc minerals that are hosted by soils, dolomitized breccias, heavily-weathered fractured and vuggy dolomitized limestones, and fine- to coarse-grained dolomitized limestones.
The results from drill holes MGC18001 through 029 at Mina Grande Centro can be found below in Table 1. A detailed map titled “Drilling and Pit/Surface Sampling at Mina Grande Centro” can be found on the Company website at www.zincone.com.

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, 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, if soil or 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 the CERTIMIN 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 values exceed 20%, it is then analyzed using a titration method. The laboratory also inserts blanks and standards as well as including duplicate analyses.
The technical content of this news release has been reviewed, verified and approved by Dr. Bill Williams, COO and Director of Zinc One, a qualified person as defined by NI 43-101.
About Zinc One Resources Inc.
Zinc One is focused on the exploration and development of prospective and advanced zinc projects in mining-friendly jurisdictions. 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 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.
