Kootenay Zinc Corp.: Sully Project Exploration Update

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 8, 2017) - Kootenay Zinc Corp. (the "Company") (CSE:ZNK)(ZNK.CN)(KTNNF)(KYH.F) provides the following update on exploration activities at the Sully project. Field programs have commenced with the arrival of excellent weather conditions and the project team is currently undertaking a number of activities at the site, including, at the East anomalies: a drill campaign at E1, detailed gravity surveying of E2, E3 and E4, prospecting and mapping, and access reconnaissance for planned drilling at E3; and new gravity surveying at the WEST anomaly.

The project team completed three diamond drill holes at E1, two at site E1S and one at E1N. As previously described, the E1 anomaly presents as a narrow north-south trending feature that has been significantly disturbed by local faulting and folding. Until recently, the E1S and E1N drill sites were among the only available permitted drill locations suitable for testing any of the East anomalies.

The three relatively shallow 'proof of concept' test holes each confirmed the complex and dissected nature of the E1 anomaly, intersecting numerous major and local fault zones in the vicinity of the target, as well as in other sections of the holes. All holes intersected significant lengths of equivalent A1f stratigraphy, with thin beds of argillite and numerous phyrrotite laminations in a CWL (carbonaceous wacke laminite)-dominant lithology. Hole SY17-14 also intersected a distinct very pale weakly dolomitic shale, Unit A1d. The lower part of the Aldridge Formation in the Hughes Range, designated A1, is unique to the range and is divided into lithostratigraphic units a (oldest), b, c, d, f and e; distinctive quartzites that characterize sub-unit e are found within sub-units c, d and f. Equivalent Sullivan-time stratigraphy occurs within unit A1c.

Drilling did not intersect any rocks with sufficiently high specific gravity values that could account for the gravity anomaly observed at E1, which remains unexplained. It is now clear that targeting such a highly-dissected anomaly is very difficult. The latest detailed gravity survey along with the drill results have further refined its geometry; cross faulting and offsets of the E1 anomaly can now be resolved.

Due to the structural complexity now evident at E1, the project team has refocused exploration on the still-undrilled E2, E3, and E4 gravity targets with detailed gravity surveying, prior to planned drilling. It is believed these significantly larger anomalies - both in strength and footprint - will be less structurally dissected. The project team will also extend its surveying to cover the WEST anomaly to assist in defining that target's dimensions and potential. Access to the proposed new drill and survey sites is readily achieved along an existing road network.
