Arizona Mining Reports High Grade Infill and Step-Out Holes in Feasibility Drilling

Arizona Mining Inc. (TSX:AZ) (“Arizona Mining” or the “Company”) announces strong results for seven exploration holes from the current drill program focused on expansion of the Taylor Sulfide Zone (“TS”) and Taylor Deeps Zone (“TDS”) located on its 100%-owned Hermosa Project in Santa Cruz County, Arizona. The drill holes highlighted in this release are successful step-out exploration and infill drill holes highlighting the continued potential for resource growth and increased grades, as distinct from the Preliminary Economic Assessment (“PEA”) (see Press Release dated April 3, 2017).

“Our exploration drilling continues to expand both the Taylor Sulfide and Taylor Deeps Zones, while the infill drilling is demonstrating great continuity between areas,” said Chief Operating Officer Don Taylor. “Although several of the 15 active drills on site are working to acquire necessary geotechnical data for the feasibility study, the balance continue to upgrade both zones. As the resource continues to grow, one impressive aspect of the recent drill results is the continued increase in silver content of the assays, especially in the Taylor Deeps Zone.”

HDS-481 is an angle drill hole on the Hardshell claim targeting the extension of the Taylor Sulfide and Taylor Deeps Zones south from the PEA resource outline. The drill hole (which is located out-of-section on Figure 3) is located 120 feet south of the PEA Deeps resource outline and encountered six significant mineralized intervals in the Taylor Sulfide Zone with a cumulative thickness of 469.5 feet (for individual mineralized intervals see Table I). Additionally, the drill intercepted a 53-foot thick section of Taylor Deeps mineralization assaying 6.0% zinc-lead and 2.2 opt silver.  Notable intervals include:

• 233 feet assaying 12.6% combined zinc-lead; and 5.5 ounces per ton (“opt”) silver (TS)
  • Including 60 feet assaying 18.4% combined zinc-lead; and 13.0 opt silver (TS)
• 53 feet assaying 6.0% combined zinc-lead; and 2.2 opt silver (TDS)

HDS-480 and HDS-483 are vertical drill holes located on the Trench claim block (see Figures 1, 2 and 3).  Both drill holes successfully intersected mineralized veins in the overlying volcanics and significant mineralization in the Taylor Deeps Zone.  HDS-480 and HDS-483 are located 1,500 and 1,300 feet west of the PEA Deeps resource outline, respectively.

HDS-480 intersected a 256.5-foot thick interval of zinc-lead-silver mineralization in the Taylor Deeps Zone.  Notable intersections within the mineralized zone are:

• 31 feet assaying 11.5% combined zinc-lead; and 7.8 opt silver (TDS)
• 30.5 feet assaying 5.4% combined zinc-lead; and 4.4 opt silver (TDS)

HDS-483 intersected an 89-foot thick interval of zinc-lead-silver mineralization in the Taylor Deeps Zone.  A notable intersection within the mineralized zone was:

• 21.5 feet assaying 12.4% combined zinc-lead; and 2.2 opt silver (TDS)

HDS-475 is a vertical drill hole on the Trench Claim block located approximately 500 feet west of the PEA resource outline (see Figures 1, 2 and 3).  The hole targeted the extension of the Taylor Deeps Zone.  HDS-475 intersected a series of vein-hosted zinc-lead-silver mineralization in the overlying volcanics and an 84.5-foot section in the Taylor Deeps Zone grading 5.1% combined lead-zinc and 2.8 opt silver.  Notable assays include:

• 8.5 feet assaying 12.8% combined zinc-lead; and 8.6 opt silver (TVS)
• 84.5 feet assaying 5.2% combined zinc-lead; and 2.8 opt silver (TDS)

HDS-482 is an angle drill hole on the Trench claim targeting the extension of the Taylor Deeps mineralization west from the PEA resource outline.  The drill hole encountered two significant veins in the overlying volcanics before intersecting a 179-foot thick interval of continuously mineralized Taylor Deeps Zone.  HDS-482 extends the Taylor Deeps mineralization approximately 130 feet west of the previous PEA resource outline.  The interval included two notable intercepts, including:

• 18 feet assaying 5.0% combined zinc-lead; and 2.6 opt silver (TDS)
• 29.5 feet assaying 6.9% combined zinc-lead; and 1.4 opt silver (TDS)

HDS-470 is an infill angled drill hole on the northeast corner of the Hardshell claim block.  The drill was successful in extending the Taylor Sulfide Zone with a thin interval of high grade zinc-lead-silver mineralization and proved continuity for the Taylor Deeps Zone with an average interval of zinc-lead-silver mineralization.  The drill intercepts in HDS-470 are approximately 1,100 feet east from the PEA resource outline.  Notable assays include:

•  5 feet assaying 22.0% combined zinc-lead; and 5.5 opt silver (TS)
• 27 feet assaying 7.2% combined zinc-lead; and 4.8 opt silver (TDS)

HDS-455 is a 500-foot step out east of the PEA resource outline and is an angle drill hole targeting the expansion of the Taylor Deeps mineralization north of the Hardshell claim block.  The drill hole encountered two mineralized intervals in the Taylor Sulfide Zone with a cumulative thickness of 73 feet (for individual intervals and assays see Table I) and an 88.5-foot thick interval of mineralized Taylor Deeps Zone.  This drill hole will expand the resource boundaries for both zones.  Notable assays include:

• 50 feet assaying 8.4% combined zinc-lead; and 1.3 opt silver (TS)
• 88.5 feet assaying 3.9% combined zinc-lead; and 1.2 opt silver (TDS)

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

Table I.  Drill Hole Assay Summary

Drill intersections with a combined zinc and lead grade of greater than 9% are bolded. Sulfide drill intervals from the Taylor Sulfide Zone and Taylor Deeps Sulfide Zone are down-the-hole drill intervals.  Vertical drill holes are considered to be within +5% of true width based on the dip of the mineralized stratigraphy at 20-25 degrees. Angle drill holes are considered to be within +15% 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 Trench Vein System (TVS).

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 30 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 re-run 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).
