Arizona Mining Reports Continued Growth Of Taylor Deeps Zone With Significant Stepout Holes Including 27 Foot Interval Assaying 19.8% Zinc, 13.3% Lead And 41.2 Opt Silver

Vancouver, B.C., May 18, 2017 – Arizona Mining Inc. (TSX: AZ) (“Arizona Mining” or the “Company”) announces the results of five exploration holes from the current drill program targeting the expansion of the Taylor Deeps Zone and definition of the Trench Vein System located on its 100%-owned Hermosa Project in Santa Cruz County, Arizona. Three of the five holes were step out exploration holes targeting expansion of the Taylor Deeps zinc-lead-silver sulfide zone.  The fifth drill hole (HDS-438) was an angle drill hole targeting the Trench Vein System, a series of steeply dipping veins which extend across the property in a northeast/southwest direction.

This latest set of drill results continues to expand the Taylor Deeps Zone and also highlights the robust nature of the Trench Vein System.  In addition to excellent zinc and lead grades, assay results show increased silver and copper values in these two zones compared to the Taylor Sulfide Zone.  Based on the results to date, the Company believes there is significant potential to increase the size of the overall resource, positively impact the mine plan in the early years, and further improve the project’s economics from the numbers included in the recently released preliminary economic assessment, which estimate a US$1.26 billion after-tax net present value, 42% after-tax internal rate of return and 1.7-year payback (see April 3, 2017 press release and April 13, 2017 technical report filed on SEDAR). In light of this, management has decided to:

  • Increase the number of drill rigs to nine from the current six and increase the budget to enable the continued resource expansion of both the Taylor Deeps Zone and Trench Vein System;
  • Delay the Feasibility Study until H1 2018, or as dictated by drill results, to allow for the current drill program to be incorporated into an updated resource estimate for the Feasibility Study;
  • Continue permitting activities to maintain production timelines and schedules;
  • Continue all other planned activities including hydrologic assessment and modeling, environmental background studies, and metallurgical and geotechnical test work.

COO Don Taylor commented: “The current drill results, coupled with prior results, clearly indicate the enormous size potential for the Taylor Deeps Zone.  The assay results from Deeps continue to indicate substantially higher silver and copper grades compared to the Taylor Sulfide Zone.  Additionally, HDS-438 is the first drill hole specifically targeting the Trench Vein System and has returned some very encouraging intercepts. Similar to the Deeps assays, the results for the veins indicate significantly higher silver and copper grades as compared to the Taylor Sulfide Zone. The drilling success in both Taylor Deeps and the Trench Vein System warrant delaying our Feasibility Study, as both zones could have a significant beneficial impact on our development plan.”

HDS-437 is an inclined hole (-82 degrees) drilled to extend an area of the previously reported Taylor Deeps mineral resource. The drill hole encountered four intervals of Taylor Sulfide mineralization, a sulfide vein and a very significant mineralized horizon in the Taylor Deeps Sulfide Zone. Most notable among the mineralized horizons are:

  • 34 feet assaying 14.8% zinc; 13.2% lead; and 4.3 ounces per ton (“opt”) silver (Taylor Sulfide Zone – “TS”)
  • 122 feet assaying 6.4% zinc; 6.5% lead; and 10.7 opt silver (Taylor Deeps Zone – “TDS”)
    • Including a 27 foot zone which assayed 19.8% zinc; 13.3% lead; and 41.2 opt silver

HDS-436 is a vertical drill hole located approximately 1,700 feet west of the Taylor Deeps resource outline (see Figure 1 and Figure 2).  HDS-436 intersected four veins in the volcanics and very robust mineralized sulfide intervals in the Taylor Deeps Zone.  The mineralization in HDS-436 included:

  • 29 feet assaying 4.9% zinc; 7.4% lead; and 6.3 opt silver (TDS)
    • Including a 8.5 foot zone which assayed 13.2% zinc; 22.9% lead; and 20.3 opt silver
  • 100.5 feet assaying 1.7% zinc; 2.5% lead; and 2.9 opt silver (TDS)
    • Including a 12.5 foot zone which assayed 9.9% zinc; 12.3% lead; and 6.6 opt silver

HDS-438 is an inclined hole (-75 degrees) drilled to test the Trench Vein System.  The veins dip approximately 65 degrees in a northeast direction.  HDS-438 encountered seven distinct veins with the first vein intersected 967 feet down the drill hole. True widths of the veins are difficult to determine based on the current drill information therefore no inference is made in that regard. All mineralized intervals are down-the-hole intercepts. Most notable among the mineralized vein results are:

  • 54.5 feet assaying 5.4% zinc; 1.8% lead; and 1.4 opt silver (Trench Vein System – “Vein”)
    • Including a 24 foot zone which assayed 11.7% zinc; 3.7% lead; and 2.2 opt silver
  • 6 feet assaying 5.3% zinc; 28.1% lead; and 18.5 opt silver (Vein)
  • 86 feet assaying 14.5% zinc; 8.7% lead; and 7.2 opt silver (Vein)

HDS-434 is an inclined infill hole (-82 degrees) drilled to test the Taylor Deeps Zone.  The drill hole intersected three veins at various levels, a single interval of Taylor Sulfide and a very robust interval in the Taylor Deeps Zone.  Most notable among the results are:

  • 141 feet assaying 4.0% zinc; 6.4% lead; and 2.2 opt silver (TDS)
    • Including a 37 foot zone which assayed 11.4% zinc; 20.0% lead; and 6.8 opt silver

For a full list of the Trench Vein, Taylor Sulfide and Taylor Deeps Sulfide mineralized intervals from these holes and HDS-429 please refer to Table I below.

 ASSAY SUMMARIES FOR HDS-429, HDS-434, HDS-436, HDS-437 & HDS-438

Drill intersections with a combined zinc and lead grade of greater than 9% are highlighted. Sulfide drill intervals are down-the-hole drill widths but are considered to be within +5% of true width based on the dip of the mineralized stratigraphy at 20-25 degrees. The exception to this are the intervals noted as veins.  It is not possible to determine the true width of the veins based on the drill density and no representation is made here regarding true width of the veins. Zones shown include; Taylor Sulfide Zone (TS); Taylor Deeps Sulfide Zone (TDS) and Mineralized Sulfide Veins (Veins).

Qualified Person

The results of the Arizona Mining Inc. drilling have been reviewed, verified and compiled by Donald R. Taylor, MSc., PG, Chief Operating Officer for Arizona Mining Inc., a qualified person as defined by National Instrument 43-101 (NI 43-101). Mr. Taylor has more than 25 years of mineral exploration and mining experience, and is a Registered Professional Geologist through the SME (registered member #4029597).

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.

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 trigger a fire assay with gravimetric finish analysis.   Gold values are determined by a 30 gm fire assay with an ICP-AES finish (Au-ICP21).
