Visualized Outcome: Arizona Mining - Hermosa-Taylor - PEA
Arizona Mining Inc owns 100% of the Hermosa-Taylor project in southern Arizona where a world-class scale sulphide carbonate replacement deposit was found in 2014 at the base of the Central deposit (formerly Manto Zone) on which AZ spent $40 million from 2006-2013 for an open-pit PFS that would have produced silver, electrolytic manganese and zinc from an oxide deposit. During 2016 AZ drilled 96 holes (109,189 m) which resulted in a PEA on April 3, 2017 for a 10,000 short ton per day underground mine with a resource of 60.8 million short tons at 4.4% zinc, 4.3% lead and 1.7 opt silver with an after-tax NPV of USD $1.26 billion (at 8%) and IRR of 42%. CapEx was USD $457 million, Sustaining Capital $500 million and OpEx $48 per short ton for a 19 year mine life. AZ plans to conduct further delineation drilling and initiate permitting in Q2 of 2017 with the goal of starting production in 2020. The current OV reflects LOM averages using metric tonnes converted from published short ton figures. Management is proceeding from PEA to a feasibility study.
Source Note: This OV is based on the assumptions in the 43-101 PEA published on April 3, 2017 treated as LOM averages with full production in all years. The PEA indicates that in the first four years high grade ore will be processed before dropping to avout 9% zinc equivalent. Note that the PEA is based on an optimized ore schedule whereas the OV uses LOM averages. The PEA used 8% as a discount rate. The OV uses a discount rate that arises from the risk factor ratings made by John Kaiser. The confidence rating has been set to "very sure" for any assumptions clearly articulated by the PEA. Otherwise they reflect John Kaiser's confidence of the provisional choices he has made.

MSV (Market Cycle S Curve): Market Speculative Value represents the typical market pricing pattern of a new discovery as it moves through its exploration-development cycle. The irrational pricing behavior of the yellow channel contrasts with the fair speculative value of the blue channel as defined by the rational speculation model because during the pre-economic study stages there is great uncertainty about how big the discovery will turn out.

Operating Rate (tpd):9,072VSMining Type:UndergroundVS
Mine Life (years):16.7
Tax Treatment:DDBM - double declining balanceVUTax Rate:42.0%SS
Operating Rate Note: 10,000 short ton per day shaft based underground operation. Converted to metric tonnes.The mine life is shorter than the 19 years in the PEA because full production is not achieved until year 3. Should AZ secure title to adjacent ground which allows driving of an adit to access the underground ore, the 10,000 tpd limit posted by the shaft scenario would be eliminated.
Mining Type Note: Facility will be entirely build on patented claims, half of tailings will be returned underground as cemented backfill, the rest dry stacked.
Est Startup Year Note: Management plans to start permitting in Q2 of 2017 which it believes will take 12-18 months. This implies that AZ will go directly from PEA to FS.
Tax Treatment Note: The technical report which would allow insights into the tax treatment deployed was not filed as of April 3, 2017.
Tax Rate Note: Federal 35%, state 7%.

Other Cost Note: PEA ised $2.00 per ST
Metal 1 Con Cost Note: $210/dmt smelter charge plus $13/mt penalty for manganese content. Transportation is $97/dmt. Note that the PEA is using the punitive 85% payability and high smelter treatment charge that have long prevailed for zinc concentrates. These figures do not reflect the potential arising for higher payability and lower treatment charges due to a shortage of zinc concentrates arising from surplus refining capacity and zinc supply that has plateaued in China and is headed for decline for non-Chinese sources.
Metal 2 Con Cost Note: $190/dmt smelter charge and $97/dmt transportation.

Management:Very Low0.5SSAZI has an impressive management team: CEO Jim Gowans is an accomplished mine builder, having built the Red Dog and Polaris zinc mines, Chairman Richard Warke has two buyouts worth $2 billion in his recent track record, one of them Augusta's Rosemont mine in Arizona, plus a huge equity stake in AZI, so raising $15-$20 million in 2016 is plausible at higher stock prices, Don Taylor knows Hermosa inside-out, Johnny Pappas helped get Romarco's Haile gold project permitted despite a "wetlands" obstacle course.

Disclaimer: A visualized outcome is one of many possible outcomes for an exploration project as it moves through the 9 stages of the exploration-development cycle from grassroots to a producing mine with failure as an outcome at any point along the way. The range of possible outcomes for the physical nature of a deposit shrinks after delivery of an initial 43-101 resource estimate. While the nature of the deposit constrains the range of mining scenarios, the cost assumptions will vary as the project moves through the feasibility demonstration stages of the cycle, which affects the economic value of the final outcome. This economic value will also vary according to the prices of the metals targeted for extraction which may change during the years it takes for a project to become a mine. An outcome visualization is thus a compilation of best guess assumptions for the key variables that drive the discounted cash flow model, the basis for assigning an economic value to a mine. An OV is not intended as a prediction, but rather as a framework that allows the incorporation of new information generated by the exploration-development cycle for the project into a valuation model on an ongoing, dynamic basis.
