VANCOUVER, British Columbia, Jan. 24, 2018 (GLOBE NEWSWIRE) -- Arizona Mining Inc. (TSX:AZ) (“Arizona Mining” or the “Company”) announces high grade results for four drill holes from the current 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 Updated Preliminary Economic Assessment (“PEA”) (see Press Release dated January 16, 2018).
“Our exploration drilling continues to expand both the Taylor Sulfide and Taylor Deeps Zones, while the infill drilling is demonstrating excellent continuity between areas,” said Chief Operating Officer Don Taylor. “As we continue to grow the resource it is amazing how many new areas of high grade mineralization have been added, especially in the Taylor Deeps Zone. These results are part of an additional 55,000 metres of infill and step-out drilling that will be included in the feasibility study, which follow the September 2017 drilling cut-off date for the just-released Preliminary Economic Assessment update.”
Of particular importance, HDS-497, collared on the northeast part of Hardshell, is an angled step-out drill hole targeting the northwest extension of the previously reported Taylor Deeps Zone intersected in HDS-477 (reported October 24, 2017). The drill hole encountered two Taylor Sulfide intervals hosted in the Epitaph Formation and a very strongly mineralized interval in the Taylor Deeps Zone. The Taylor Deeps intercept extends the mineralization 290 feet northwest of HDS-477. Significant mineralization in the Taylor Deeps includes:
- 31 feet assaying 40.9% combined zinc-lead; and 11.7 ounces per ton (“opt”) silver (TDS)
o within an 81-foot thick interval assaying 27.1% combined zinc-lead; and 6.8 opt silver (TDS)
HDS-498 and HDS-493 are vertical infill drill holes targeting Taylor Sulfide (TS) mineralization hosted in the Concha (TS), Scherrer (TS) and Taylor Deeps (TDS) domains encountered in HDS-338 and HDS-425 (previously reported on May 5, 2016 and April 20, 2017, respectively). The targeted Concha and Scherrer domains continue to expand with the addition of these holes and will have a positive impact on the grade and tons of the Taylor Sulfide resource. In addition to improving the Taylor Sulfide Zone, these intercepts in the Taylor Deeps confirm the continuity and robustness of the Deeps mineralization in this area.
HDS-498, located 200 feet west of HDS-425, intersected three veins, three Taylor Sulfide intervals and a well mineralized Taylor Deeps intersection. Notable mineralization in HDS-498 includes:
- 81 feet assaying 30.0% combined zinc-lead; and 8.3 opt silver (TS)
- 137 feet assaying 14.5% combined zinc-lead; and 3.0 opt silver (TDS)
HDS-493, located 600 feet west of HDS-425, encountered three veins, three Taylor Sulfide intervals and two Taylor Deeps intervals. Most notable among the mineralized intervals:
- 17 feet assaying 22.8% combined zinc-lead; and 4.1 opt silver (TDS)
o within an 89-foot thick interval assaying 6.6% combined zinc-lead; and 1.3 opt silver (TDS)
HDS-484 is an infill angled drill hole targeting Taylor Sulfide mineralization. The drill hole encountered mineralization in all three stratigraphic domains within the Taylor Sulfide Zone (Concha, Scherrer and Epitaph). The hole will expand the Taylor Sulfide resource boundary to the southwest and extend the boundary along strike to the southeast. Most notable among the mineralized intervals are:
- 22.5 feet assaying 15.1% combined zinc-lead; and 6.7 opt silver (TS)
o within a 151-foot thick interval assaying 6.5% combined zinc-lead; and 1.9 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.

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).

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).
