KOOTENAY ZINC CORP. ANNOUNCES UPDATES ON SULLY PROJECT
Kootenay Zinc Corp.'s Sully project team has recently completed drill hole SY17-11, which tested a portion of the E1 zone of the East anomaly. The hole did not intersect an extensive high-density mass, but did intersect a number of geologically significant features with similarities to the Sullivan sedimentary environment. The project team continues to review and evaluate the new core and downhole geophysics.
At a hole depth corresponding to the projected gravity anomaly, an increase in thickness of intervals of carbonaceous wacke laminate (CWL), as well as an increase in proportion of CWL to argillite, was noted. A 20-metre-thick CWL marks the top of the lower Aldridge formation at Sullivan, 30 kilometres west of Sully. That interval splits and interfingers over 200 metres with ore and associated unique sedimentary rocks that comprise the Sullivan subbasin. The thicker-than-normal intervals of CWL interfingering with argillite in SY17-11 suggest a subbasin setting is present at Sully. The gravity anomaly suggests proximity to a mass in rocks deposited at an equivalent time in what appears to be a subbasin that is entirely consistent with the Sullivan sedex model.
Rare lead and zinc sulphides are also observed at a hole depth of 283 and at 298.8 metres: one associated with laminated iron sulphides and the other in a quartz veinlet. Iron sulphides, predominantly pyrrhotite that commonly is accompanied by a minor amount of pyrite, are present throughout much of the hole. These sulphides are primarily in bedding parallel laminations; however, disseminations and veinlets are also present. The laminations are one to five millimetres thick and where most abundant are spaced at 10-centimetre to one-metre intervals. These observations may indicate fringe mineralization of a sedex-style gravity mass.
Drill hole SY17-11 drilled the upper portion of unit A1c of the Hughes Range facies of the Aldridge formation. Two small (up to five metres) gabbro bodies, likely dikes, were intersected. Specific gravity measurements of these rock types are in a fairly narrow range, and there is little to no contrast with the gabbro intersected, indicating that gabbro is unlikely to account for the anomaly. Strata in the hole are highly strained, and they display a steeply overturned west dip, consistent with the lower limb of the Hughes Range anticline described in previous news releases.
The project Team also completed new downhole electromagnetic (EM) and magnetic (MAG) survey on holes SY16-10 and SY17-11 to expand geophysical definition of the targets. The EM results did not identify conductive targets nearby, which may not be conclusive for targeting purposes at Sully; however, a modest MAG anomaly was noted and final results will be reported shortly. MAG anomalies have also been recorded in other drill holes at Sully, and the company has recently initiated a ground MAG survey over the extent of the gravity anomalies. The results of that work will be reported once the data have been collected and interpreted.
The company will await the results and interpretation of all of the recently collected data before drilling next planned holes, expected to start immediately following spring breakup conditions. The company also anticipates permitting of new drill sites to be completed during this time.
About Kootenay Zinc Corp.
Kootenay Zinc is a mineral exploration and development company based in Vancouver, B.C., that is presently targeting the Sully property.
The Sully property comprises 1,375 hectares located approximately 30 kilometres east of Kimberley, B.C., and overlies rocks of similar age and origin as those which host the world-class Sullivan deposit, owned by Teck Resources Ltd. Sullivan was discovered in 1892, and is known to be one of the largest sedex deposits in the world. Over its 100-year lifetime, Sullivan produced approximately 150 million tonnes of ore, including approximately 300 million ounces of silver, eight million tonnes of zinc and eight million tonnes of lead.
