VANCOUVER — Arizona Mining (TSX: AZ; US-OTC: WLDVF) has advanced its Taylor zinc-lead-silver sulphide deposit at a rapid pace over the past 18 months, and that hard work culminated in the release of a preliminary economic assessment (PEA) on April 3. The company is targeting first production from a proposed 9,100-t/d operation by 2020.
Arizona completed 70 surface diamond drill holes in its 2016-2017 program targeting stratabound carbonate-replacement resources at Taylor. The deposit is the down-dip sulphide extension of the Hermosa Central silver-manganese oxide project, which sits in the Patagonia Mountains around 80 km due southeast of Tucson, Arizona.
The newly minted mine plan is based on an updated mineral resource that establishes 65% of total contained metals in the measured and indicated categories. Taylor now hosts 72.4 million measured and indicated tonnes grading 4.3% zinc, 4.4% lead, 88 g/t silver and 0.1% copper. The base case for the resource assumes a 4% zinc equivalent cut-off grade.
