Exploration and diamond drilling at Canada Zinc Metals‘ (CZX-V) Cardiac Creek Sedex zinc-lead-silver deposit on its Akie property, 260 km northwest of the town of Mackenzie in northeastern B.C., started in May – and so far the company has completed six holes and received assay results for four, including the previously reported holes 11-92 and 11-93, and new results from 11-95 and 11-96.
The holes provide infill information both up- and down-dip, and test the strike extent of the high-grade trend along the southeastern edges of the deposit. Step-out drilling was conducted to the southeast designed to expand the known limits of the deposit.
Hole 11-92 returned 6 metres of 1.83% zinc, 0.30% lead, 5.43 grams silver per tonne and 2.13% zinc plus lead, including 2 metres of 3.41% zinc, 0.58% lead, 7.72 grams silver and 3.99% zinc plus lead. Hole 11-93 cut 15 metres of 6.61% zinc, 1.45% lead, 9.84 grams silver and 8.06% zinc plus lead, including 9 metres of 8.60% zinc, 2.02% lead, 11.82 grams silver and 10.62% zinc plus lead.
Hole 11-95 represents an approximate 100-metre step-out along strike from the high-grade intercept in 11-93 to the southeast. Results from this hole demonstrate that the mineralization remains open to the southeast. The hole cut 13 metres of 3.98% zinc, 0.61% lead, 6.84 grams silver and 4.59% zinc plus lead, including 3 metres of 7.40% zinc, 1.28% lead, 10.13 grams silver and 8.68% zinc plus lead.
Hole 11-96 returned 26 metres of 4.80% zinc, 0.84% lead, 7.7 grams silver and 5.64% zinc and lead, including 13 metres of 7.15% zinc, 1.24 grams lead, 11.18 grams silver and 8.39% zinc plus lead, and 5 metres of 8.59% zinc, 1.43% lead, 12.43 grams silver and 10.01% zinc plus lead. The area remains open for further drilling and shows continued expansion of the deposit towards the surface and Cardiac Creek.
The Akie zinc-lead property is located in the southernmost Kechika Trough of the regionally extensive Paleozoic Selwyn basin, one of the most prolific sedimentary basins in the world for the occurrence of Sedex zinc-lead-silver and stratiform barite deposits, Canada Zinc says on its website.
Inmet Mining (IMN-T) drilled the Akie property from 1994 to 1996, and Canada Zinc has drilled it since 2005. The deposit is hosted by siliceous, carbonaceous, fine-grained clastic rocks of the Middle to Late Devonian Gunsteel formation.
In 2008 Canada Zinc outlined a National Instrument 43-101 compliant inferred resource for Cardiac Creek totalling 23 million tonnes grading 7.6% zinc. 1.5% lead and 13 grams silver per tonne, which amounts to 3.95 billion pounds zinc, 780 million pounds lead and 8.95 million oz. silver.
About 20 km to the northwest of Cardiac Creek, two similar deposits, Cirque and Cirque South Cirque, are being explored by a joint venture between Teck Resources (TCK-T, TCK-N) and Korea Zinc.
In addition to the Akie property, Canada Zinc controls a large, contiguous group of claims that make up the Kechika regional project. These claims are underlain by geology identical to that on the Akie property. The Kechika project includes the fully owned Mount Alcock property.
