Zinc One Announces Positive Initial Resource Estimate at Bongará Zinc Mine Project, Peru

The estimate consists of an Indicated Mineral Resource of 812,000 tonnes averaging 18.9% Zn containing 339,000,000 lbs 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 lbs of Zn at a 10% Zn cut-off.

Greg Crowe, Director of Zinc One, stated, “This initial Mineral Resource estimate quantifies the amount of high-grade zinc in an area of known near-surface mineralization along a 1.4-kilometre trend. Further, geologic mapping and surface sampling confirms the potential of the larger Bongará Zinc Mine project to host additional significant zinc mineralization.   Overall, the area of the new mineral resource estimate occupies only a small area along the strike of eight kilometres of prospective stratigraphy.  In 2019, we plan to carry out additional drilling that includes upgrading the confidence level of the currently defined Inferred Mineral Resources and to expand the overall resource at nearby undrilled high-priority targets located between Mina Chica and Mina Grande Norte and northwest of Mina Chica at Campo Cielo.”

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.
