Arizona Mining increases resource on Taylor Deposit to 39.4 million tonnes at 11 % ZnEq

VANCOUVER, Feb. 1, 2016 /CNW/ - Arizona Mining Inc. (TSX: AZ) ("Arizona Mining" or the "Company") is pleased to announce a resource update for the Taylor Zn-Pb-Ag sulfide deposit located on its Hermosa Project in Santa Cruz County, Arizona USA. The deposit now comprises 39.4 million tonnes in accordance with the NI 43-101 Inferred Mineral Resource category grading 11.04% zinc equivalent ("ZnEq") utilizing a 6% ZnEq cutoff grade.

CEO Jim Gowans commented, "This updated resource estimate confirms what the drill results and geology have been telling us for some time - that we have the potential makings of a significant zinc/lead/silver deposit. All drill holes completed since we initiated the drill campaign in the fall of 2014 encountered relatively high grade sulfide mineralization over significant thicknesses. The deposit remains open for expansion to the north, west and south over ground controlled by the Company and will be tested through an extensive drill campaign.  This resource estimate, combined with the expansion potential and recently released metallurgical results, clearly indicate that the Taylor Deposit could be one of the best growth stories in base metals for 2016."

Taylor Deposit Inferred Mineral Resources

The resource is based on assay results from 25 surface diamond drill holes, totaling 19,648 meters (64,461 feet) of drilling, which have all intersected stratabound carbonate replacement sulfide mineralization within the Taylor Deposit.  The updated Mineral Resource Estimate was prepared by Metal Mining Consultants Inc. of Highlands Ranch, Colorado.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of mineral resources will be converted to mineral reserves.  Inferred Mineral Resources are based on limited drilling (25 holes) which suggests the greatest uncertainty for a resource estimate and that geological continuity is only implied.  Additional drilling will be required to verify geological and mineralization continuity and there is no certainty that all of the inferred resources will be converted to measured and indicated resources.  Quantity and grades are estimates and are rounded to reflect the fact that the resource estimate is an approximation.

Discontinuous and isolated pods of mineralization were excluded from the mineral resource estimate. Excluded blocks do not represent mineable volumes of material and do not meet the reasonable prospects of eventual economic extraction for resource classification. Continuous blocks, that imply continuity of mineralization, were further evaluated to establish a breakeven ZnEq cutoff grade. It is assumed that industry standard froth flotation will be used as the mineral processing method. Assumptions used to calculate a breakeven ZnEq cut-off grade are $US45.75/tonne (mining, processing and G&A), 85% zinc recovery and $US0.85 per lb. zinc selling price. A breakeven ZnEq cut-off grade of 3% was estimated. A 6% ZnEq grade was selected as the Base Case cut-off grade for this updated resource estimate.

Mineral Resource Model
A total of three geologic domains were modeled for the Taylor Deposit (Manto, Top and Bottom), which consists of stratabound skarn and massive sulfide carbonate (limestone) replacement mineralization. The Top and Bottom domains were created to define the upper and lower limits of sulfide mineralization which typically is the boundary between the overlying Cretaceous volcanic units and lower Concha, Scherrer, Epitaph carbonate units, as well as two oxidized ore types. Within the Top and Bottom domains are horizons of sulfide and oxide mineralization. Sulfide mineralization is hosted in intervals marked as containing no iron oxide minerals but containing sulfide minerals of lead, zinc, copper and iron. Oxide mineralization, those zones in the core containing predominantly iron oxide, is mineralogically different from the sulfide mineralization and is excluded from this mineral estimate.

The mineral resource was estimated using 19,648 meters (64,461 feet) of drilling from 25 drill holes that intercepted sulfide mineralization associated with the Taylor Deposit. Composites were constructed using 20 feet (6.1 meter) down-the-hole composite lengths. A total of 2,646 x 20 ft (6.1 meter) Ag composites and 2,647 x 20 ft. (6.1 meter) Cu, Pb and Zn composites were used to estimate the mineral resource. Metal grades were interpolated using inverse distance to the fifth (ID5). Estimation parameters were determined by the trend of the mineralization, and strike and dip of the lithologic units that host the deposit.

Qualified Person
Scott Wilson, President of Metal Mining Consultants, is an independent qualified person as defined by National Instrument 43-101 and has approved and verified the information in this news release in relation to the Taylor Deposit resource estimates. Mr. Wilson is a Certified Professional Geologist and member of the American Institute of Professional Geologists (CPG #10965) and a Registered Member (#4025107) of the Society of Mining, Metallurgy and Exploration, Inc., a professional association and designation recognized by the Canadian regulatory authorities.

Assays and Quality Assurance/Quality Control
To ensure reliable sample results, the Company has a rigorous QA/QC program in place that monitors the chain-of-custody of samples and includes the insertion of blanks, duplicates, and certified reference standards at statistically derived intervals within each batch of samples. Core is photographed and split in half with one-half retained in a secured facility for verification purposes.

Post March 2014, sample preparation (crushing and pulverizing) has been performed at ALS Minerals Laboratories, an ISO/IEC accredited lab located in Tucson, Arizona. ALS Minerals Laboratories prepares a pulp of all samples and sends the pulps to their analytical laboratory in Vancouver, B.C. Canada for analysis. ALS analyzes the pulp sample by ICP following a 4-acid digestion (ME-ICP61 for 33 elements) including Cu (copper), Pb (lead), and Zn (zinc).  All samples in which Cu (copper), Pb (lead), or Zn (zinc) are greater than 10,000 ppm are rerun using four acid digestion with an ICP – AES finish (Cu-OG62;Pb-OG62; and Zn-OG62) with the elements reported in percentage (%).   Silver values are determined by ICP ((ME-ICP61) with all samples with silver values greater than 100 ppm repeated using four acid digestion with an ICP-AES finish (Ag-OG62) calibrated for higher levels of silver contained.  Any values over 1,500 ppm Ag triggers a fire assay with gravimetric finish analysis.
