INZINC INTERSECTS 6.8M OF 16.5% ZINC
Inzinc Mining Ltd. has released results of the phase 1 drill program at the company's 100-per-cent-owned West Desert zinc-copper project in western Utah. The company completed the first phase of drilling with five deep holes totalling 3,500 metres. The drill program focused on exploration and expansion of the large zinc resources outlined in the 2014 preliminary economic assessment.
Highlights:
-
As previously disclosed, drill hole WD18-01, drilled west of the existing deposit, intersected a thick interval of 15.4 metres of 6.3 per cent zinc, 0.1 per cent copper and 67 g/t indium at 340 m below surface and approximately 60 m west of the known boundary of the existing sulphide resources.
-
WD18-05, drilled below WD18-01, intersected shallow, high-grade sulphide mineralization over 6.8 m averaging 16.5 per cent Zn, 0.3 per cent Cu, 60 g/t In and 14 g/t silver at a downhole depth of 142 m. The hole was drilled to the west of existing sulphide resources.
-
WD18-02, drilled to the east of the existing resources and 400 m to the east of WD18-01 intersected multiple, narrow high-grade zones including 1.5 m of 11.6 per cent Zn, 0.1 per cent Cu, 4 g/t In and 53 g/t Ag, and established the eastward expansion potential of the CRD (Deep) zone by 175 m to the east.
-
WD18-03, drilled 1.27 kilometres to the east of WD18-01, intersected high-grade silver mineralization 320 m beneath the historic Utah silver mine with a narrow intercept of 0.3 m of 1,402 g/t Ag, 1.2 g/t Au and 44.5 per cent lead.
-
WD18-04, drilled 120 m to the west of WD18-01, intersected 1.8 m of 8.6 per cent Zn and 339 g/t In at 206.7 m downhole in a thick oxidized interval suggestive of deeper sulphide mineralization below.
"Our goal for the phase 1 program was to explore the wide range of target areas and styles of mineralization occurring across the property to determine a clear focus for phase 2 programs. The shallow and high-grade zones intersected to the west of the WD deposit demonstrate that the limits of this important mineralization have yet to be determined," stated Wayne Hubert, chief executive officer of Inzinc. "While the drilling to the east intersected numerous narrow high-grade zones that will require follow-up in the future, the phase 2 programs will now target the high-grade western expansion of the deposit prior to launching advanced economic studies. The next phase of drilling is being planned and permitted."
Exploration
drill holes to the
west
of the existing resources
Three holes, WD18-01, WD18-04 and WD18-05, were drilled to the west of the existing West Desert resources to assess the potential for higher-grade zinc, copper and associated indium in the shallow western portion of the Main zone of the WD deposit. Large intersections of high-grade zinc and copper in sulphide were outlined between 150 m and 350 m below surface in holes WD18-01 and WD18-05. This area of interest, also evident farther to the west in hole WD18-04, is a priority target for further drilling.

** WD18-01 released on June 6, 2018.
WD18-05 was drilled beneath WD18-01 to test the down-dip extension of several intersections, including the previously reported shallow high-grade lens with two m of 11.8 per cent Zn, 0.5 per cent Cu and 73 g/t In. At approximately 150 m below surface, the drill hole intersected high-grade sulphides over a 6.8 m interval averaging 16.5 per cent Zn, 0.3 per cent Cu, 60 g/t In and 14 g/t Ag. Phase 2 exploration will consider 50 m stepouts along strike and to depth to further delineate the high-grade lens. The steep angle of WD18-05 and downhole deviation may have prevented a complete test of the deeper intersections in WD18-01.
WD 18-04, drilled 120 m to the west of WD18-01, intersected the targeted horizon at shallow depths and encountered a thick (41 m), highly oxidized zone containing greater than 50 per cent iron. Visible copper and zinc oxides indicate oxidation and leaching of zinc and copper sulphide mineralization. Phase 2 exploration will include plans to drill beneath this oxidized zone to intersect the underlying sulphides, similar to what was accomplished with WD18-05.
Exploration drill holes to the east
of the existing resources
Exploration to the east of the existing West Desert resources was tested with two deep holes, WD18-02 and WD18-03. The holes were drilled to explore silver-rich zinc mineralization previously intersected in both the upper east portion of the resources and 650 m east, below the past-producing Utah silver mine. Both holes also tested deeper targets for extensions of copper-zinc mineralization at the CRD (Deep) zone of the WD deposit and below the Utah mine. Holes WD18-02 and WD18-03 intersected narrow high-grade zones that will require follow-up in the future.

WD18-02 explored the eastern edge of the WD deposit and intersected multiple narrow zones of mineralization. Several deeper intersections, between 701 m and 728 m downhole, represent the extension of the CRD (Deep) zone. The previous known limit of the CRD (Deep) zone is located 175 m west of these intersections and the intervening space is open for future resource expansion.
WD18-03 intersected high-grade silver mineralization 320 m below the historic Utah silver mine with a narrow 0.3 m intersection grading 1.4 kilograms per tonne silver and 44.5 per cent lead. This drill hole has been left open for possible re-entry for directional drilling of additional targets.

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 were 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 and secured on pallets. The pallets were delivered to R&L Freight Lines' Salt Lake City facility by Inzinc contract geologists 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 10th sample. Results from the QA/QC samples were within industry norms.
