Diamond Drill Core in Box


Inzinc Mining Ltd. (IZN.V)  has provided assay results from the first drill hole, WD18-01, of the continuing drill program at the 100-per-cent-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.


  • Thick interval of 50.6 feet of 6.28 per cent zinc, 0.4 per cent copper, 66.8 grams per tonne indium (In) at significantly higher grade than 2014 resource average in a previously undrilled area;
  • Significant copper interval with 15.0 ft of 2.1 per cent Cu, also in a previously undrilled area;
  • Shallow high-grade intercept of 6.6 ft of 11.77 per cent Zn, 0.5 per cent Cu and 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 10 ft 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 U.S. government.

"With an aggregate of over 100 feet of mineralization intersected 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, chief 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 Utah mine. Currently, the company is drilling a deep hole 650 metres to the east of the existing resource and is currently at approximately at 2,400 feet down hole of a planned 3,300-foot hole. Inzinc will release the results of this hole when assays become available.

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 quality assurance/quality control procedures, Inzinc inserted a standard, blank or preparation duplicate every 10th sample. Results from the QA/QC samples were within industry norms.
