Arizona Mining’s Expanded Drill Program Hits More High-Grade Mineralization Outside PEA Resource Outline
- 62 FEET ASSAYING 32.5% ZINC-LEAD AND 5.8 OPT SILVER
- 35 FEET ASSAYING 24.0% ZINC-LEAD AND 21.0 OPT SILVER
- 36.5 FEET ASSAYING 17.1% ZINC-LEAD AND 3.1 OPT SILVER
- 17.5 FEET ASSAYING 14.5% ZINC-LEAD AND 2.2 OPT SILVER
Vancouver, B.C., August 8, 2017 – Arizona Mining Inc. (TSX: AZ) (“Arizona Mining” or the “Company”) announces the results of three exploration holes from the current nine rig 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 indicating the potential for resource growth and increased grades from the Preliminary Economic Assessment (“PEA”) (see Press Release dated April 3, 2017).
“The drill results continue to significantly expand the Taylor Sulfide and Taylor Deeps Zones and show higher zinc-lead-silver grades. It is clear that the expanded drill program continues to not only add tons to the ultimate size of the deposit, but more importantly, they are higher grade tons that should benefit the economics of the project,” said Chief Operating Officer Don Taylor.
HDS-459 is a vertical hole located on the northwest corner of the Hardshell claim block, 150 feet east of the PEA resource outline (see Figure 2). The hole was drilled from the HDS-330 pad (original hole directed at the sulfide deposit) and targeted the Taylor Deeps Zone and extensions of the Taylor Sulfide Zone outside the resource grade shell used for the PEA. HDS-459 intersected robust sulfide intercepts in all three carbonate units in the Taylor Sulfide Zone and also in the Taylor Deeps Zone. The mineralization in this drill hole will extend both zones for the next resource calculation. Notable assays include:
- 36.5 feet assaying 10.2% zinc; 6.9% lead; and 3.1 ounces per ton (“opt”) silver (TS)
- 35 feet assaying 10.8% zinc; 13.3% lead; 21.0 opt silver; and 1.2% copper (TDS)
HDS-449 is a vertical hole located approximately 175 feet northwest of the Taylor sulfide PEA resource outline in the southeast portion of the Trench claim block (see Figure 1). The drill hole targeted the extension of the Taylor Sulfide Zone and infilling of the Taylor Deeps Zone between the resource outline and previously released drill hole HDS-453 (for results see Press Release dated July 13, 2017). The drill hole intersected a 138-foot-thick interval of Taylor Sulfide mineralization. The mineralization in HDS-449 will expand both the Taylor Sulfide and Taylor Deeps Zones beyond the PEA resource. Significant assays from HDS-449 include:
- 138 feet assaying 7.4% zinc; 9.3% lead; and 3.3 opt silver (TS)
- Including 62 feet assaying 14.1% zinc; 18.4% lead; and 5.8 opt silver
HDS-448 is a vertical infill drill hole located within the PEA resource outline to infill a gap of approximately 400 feet in the drilling (see Figure 1). HDS-448 intersected five significant mineralized horizons in the Taylor Sulfide Zone with a cumulative thickness of 213 feet (for individual intervals see Table I). Most notable of the results from HDS-448 are:
- 25 feet assaying 6.7% zinc; 5.2% lead; and 1.6 opt silver (TS)
- 17.5 feet assaying 7.4% zinc; 7.1% lead; and 2.2 opt silver (TS)
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 highlighted. Sulfide drill intervals from the Taylor Sulfide Zone and Taylor Deeps Sulfide Zone are down-the-hole drill intervals 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 Trench Vein System (TVS).

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).
