TORONTO, Feb. 15, 2017 (GLOBE NEWSWIRE) -- Nevada Zinc Corporation (“Nevada Zinc” or the “Company”) (TSX-V: NZN ) is pleased to report drill hole assay results for additional holes from its Phase 5 drill program at the Company’s Lone Mountain zinc project (the “Project”).
The Company’s recently completed Phase 5 exploration program included 24 reverse circulation drill holes, surface geological mapping and prospecting, limited geophysical test work and specific gravity testing of mineralized material.
Nevada Zinc President and CEO, Bruce Durham commented, “The Phase 5 assay results reported today and on January 11, 2017 expand the limits of both the Discovery zone area mineralization and the mineralization near the historic Mountain View Mine. The drill holes were designed to test the limits of the known areas of mineralization. We are very encouraged by the results from the Phase 5 drill holes and we are currently planning our next phase of exploration work on the Project. As an exhibitor at the upcoming Prospectors and Developers annual conference in Toronto we look forward to discussing the continuing progress of the Company at booth #2215 on Tuesday March 7, 2017 and Wednesday March 8, 2017.”
Highlights
- Drill hole LM 16-77 intersected significant near surface zinc mineralization over a 36.58 metre interval from 21.34 metres grading 4.39% zinc and 0.04% lead (4.43% zinc+lead) southwest of the historic mine workings on the Mountain View Mine property.
- Drill hole LM-16-78 intersected a 10.67 metre interval of zinc mineralization grading 6.42% zinc starting at a downhole depth of only 21.34 metres.
- The Discovery zone zinc mineralization remains untested at depth to the northeast beyond holes LM-16-63, 64 and 65 that were reported January 11, 2017. Drill hole LM-16-64 in that release intersected a broad zone of zinc mineralization from 184.4 metres downhole that averaged 3.99% zinc and 0.21% lead over 53.34 metres, including a 30.48 metre interval that averaged 5.99% zinc.
All zinc and lead mineralization intersected to-date on the Project is non-sulphide type mineralization (importantly, the mineralization outlined to-date is not a mixture of sulphide and non-sulphide which can complicate the extractive metallurgy process).
No drilling has yet been completed to test for deeper sulfide mineralization beyond the depths of the drilling completed by the Company. Drill Hole Summary Information

Sample Preparation and Quality Control
Supervision and organization of reverse circulation drilling chip samples was undertaken by Company personnel. Samples were collected at 5 foot intervals from a rotating wet splitter assembly attached to the drill rig. Chip tray samples were collected from the reject side of the wet splitter. The splitter was adjusted to produce 10 lbs. to 20 lbs. of sample. Samples were collected from the drill in cloth bags by employees of New Frontier Drilling under the supervision of Company personnel. Samples were catalogued by Nevada Zinc geologists and stored in a secure location. Certified reference standards were placed in the sample stream of each drill hole at random intervals. Blank material was also inserted at random intervals.
Assay Techniques
Preparation of the samples was done at the ALS Chemex Elko, NV facility. A 250 gram master pulp was taken, then splits were sent to ALS’s North Vancouver, BC facility or their Reno, NV facility. A 48 element package using a 4 acid digestion with ICP-AES and ICP-MS was completed on all samples. For zinc and lead values exceeding the limits of the 48 element package (1% zinc or lead), the procedure was to use a 4 acid digestion with ICP-AES or AAS finish (ore grade analysis). In the case of values exceeding the limits of the ore grade analysis (30% zinc, 20% lead), the procedure was to use specialized titration methods.
Laboratory QA/QC
Quality control samples from the lab include numerous control blanks, duplicates and standards. Reference standards used include OREAS-133b, OREAS-134b, OGGeo08, and CZN-4. No issues were noted with analytical accuracy or precision.
ALS Chemex’s Reno, Elko, and North Vancouver locations have ISO/IEC 17025:2005 accreditation.
