2018 Technical Report on Seal Zinc Deposit
During the 2018 fiscal year, Aston Bay completed an initial mineral resource on its 100% owned Seal Zinc deposit. The deposit is a stratabound body hosted in sandy dolostone and sandstone within a thick section of Paleozoic dolostones, and was discovered by Teck in the mid-1990s. The Seal Zinc deposit is approximately 30 km to the west of the high-grade Storm Copper prospect.
The Seal Zinc deposit is estimated to contain 1.006 million tonnes (“Mt”) at a grade of 10.24% zinc and 46.5 grams per tonne (“g/t”) silver, using a cutoff of 4.0% zinc equivalent. The estimate is based on diamond drilling conducted by Teck in 1995-96 and Noranda in 2001.
Known mineralization has a thickness of up to 20 m, extends for over 400 m along strike and 50 to 100 m down-dip, and is partially fault-bound. Seal Zinc is interpreted to be a Mississippi Valley–type (“MVT”) deposit, with geological similarities to the Polaris deposit located to the north in the same Paleozoic dolostone succession. A large hydrothermal “pseudobreccia” alteration zone in the footwall of the deposit contains minor zinc mineralization and probably represents the feeder zone. MVT deposits are known to occur in clusters, and Aston Bay believes there is exploration potential along strike for discovery of additional mineralization.
