InZinc Extends West Desert High-Grade Mineralization to the West

Vancouver, BC – InZinc Mining Ltd. (TSX-V: IZN) (the “Company”) is pleased to report assay results from the first

drill hole, WD18-01, of the ongoing drill program at the 100% owned West Desert project in western Utah. WD18 -01

was drilled to explore an untested area on the western edge of the Main Zone of the WD deposit.

Highlights

• Thick interval of 50.6 ft of 6.28% Zn , 0.4% Cu, 66.8 g/tonne (g/t) Indium ( In) at significantly higher grade

than 2014 resource average in a previously un-drilled area

• Significant copper interval with 15.0 ft of 2.1% Cu, also in a previously un-drilled area

• Shallow high-grade intercept of 6.6 ft of 11.77% Zn, 0.5% Cu, 72.6 g/t In

• Improved potential for shallow zinc-copper-indium tonnage immediately west of WD18-01

• Significant widths of indium mineralization at higher grades 50.6 ft of 66.8 g/t In, 30 ft of 183.9 g/t In and 10ft

of 272.7 g/t In — higher than the 2014 resource of about 30 g/t In

• Earlier this year, Indium was declared one of the 23 critical elements by the US government

“With an aggregate of over 100 feet of mineralization int ersected in our first hole, we are very pleased with these

results. Our goal was to assess the potential for higher grade zinc and the presence of indium in the shallower western

portion of the deposit. In both cases the objective was met with success leaving us with significant room for expansion

further to the west,” commented Wayne Hubert, CEO of InZinc.

Next Steps

Drilling continues at the site with holes to the east and proximal to the past -producing Utah silver mine. InZinc is

exploring for both silver -rich and copper -rich zinc mineralization that was intersected in historical drill hole CC -43,

located below the U tah mine. Currently, the Company is drilling a deep hole 650 met res to the east of the existing

resource and is currently at approximately at 2400 f eet downhole of a planned 3300 foot hole. InZinc will release the

results of this hole when assays become available.

About InZinc

InZinc is focused on growth in zinc through exploration and expansion of the advanced stage West Desert project

(100%) in Utah and exploration of the early stage Indy project (100% option) in British Columbia. West Desert has a

large underground resource open for expansion and has district scale exploration potential. A West Desert preliminary

economic assessment completed in 2014 forecasted 1.6 billion pounds of zinc production over 15 years.

Indy comprises both near surface exploration targets and regio nal discovery potential. Both zinc projects are well

located with easy access and existing infrastructure.

for the accuracy or the content of the historical reports.

Quality Assurance/Quality Control

Drill core was collected from the drill site and delivered to the InZinc West Desert camp by the drill contractor or InZinc geologic

contract staff. The core was photographed, logged, and intervals selected for sampling. Core samples were split using a

diamond saw on site with one-half of the core submitted for assay and the other half stored in wooden core boxes on site.

Bagged, sawn core was placed in plastic burlap bags (“rice bags”) and secured on pallets. The pallets for this hole were delivered

to an expeditor in Delta, Utah where they were collected by a shipping company for shipment to MS Analytical Services in

Langley, B.C., Canada for analysis. Samples were prepared by MS Analytical and analyzed by ICP-OES, ICP-MS, and fire assay

methods. In addition to the in-house QA/QC procedures, InZinc inserted a standard, blank, or preparation duplicate every tenth

sample. Results from the QA/QC samples were within industry norms.

The PEA is considered preliminary in nature. It includes Inferred mineral resources that are considered too speculative to have the

economic considerations applied that would enable classification as mineral reserves. There is no certainty that the conclusi ons

within the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Long-

term metal prices used in the study included zinc at $1/lb, copper at $3/lb, iron ore at $105/t (62% Fe, CFR-Tianjin), gold at $1,300/oz

and silver at $21/oz. The technical report is entitled “Technical Report on the West Desert Zinc -Copper-Indium-Magnetite Project -
