Nevada Copper Hits with 19 Mineralized Holes: Enhances Potential of Open Pit Economics

 

 

 

 

 

Nevada Copper Corp. (TSX: NCU) is pleased to announce results from 19 holes in and near the open pit project which is located 4km from the Company’s underground mine, both situated at its 100% owned Pumpkin Hollow copper project.  All of the 19 holes have hit copper mineralization, with 9 holes hitting high-grade mineralization, including hole NC18-22, located outside of the current pit limits, which intercepted 6.9 meters true thickness averaging 4.12% copper between 175.7m and 187.0m. In total, 26 holes were drilled during the 2018 Open Pit Project expansion work program and the results indicate a new high-grade zone, new lenses of mineralization and the continued success of the waste-to-ore conversion program. None of these holes were included in the recent preliminary economic assessment study (see news release dated September 10, 2018). These 26 holes will be included in the upcoming pre-feasibility study anticipated Q1, 2019 and have the potential to enhance the size and economics of the Open Pit Project.

 

 

Results Highlights

 

  • A total of 26 Holes over 9,800 meters have been drilled this year, including 19 New Mineralized Drill Holes: All 26 holes encountered multiple zones of mineralization. Results include:
    • Hole NC18-06 intersected 9.2 meters true thickness averaging 1.09% copper
    • Hole NC18-14 intersected 13.0 meters true thickness averaging 2.42% copper
    • Hole NC18-23 intersected 29.4 meters true thickness averaging 0.71% copper, including 5.7 meters true thickness averaging 2.60% copper.
  • Demonstrates potential for waste to ore conversion and upgrading of inferred-category ore: The program intersected strong mineralization in the Northern Extension target area outside and within the walls of the Open Pit Project mine plan that have been classified as waste rock. It also targeted areas classified as inferred category ore with the goal of upgrading to indicated category. Converting the waste rock may reduce stripping costs and extend the ore body.
  • New High-Grade Zone discovered outside of the existing Open Pit Project1 boundaries: Three of the holes encountered high-grade mineralization outside of the walls of the existing Open Pit Project plan. Drill hole NC18-19 intersected 9.9 meters true thickness averaging 3.48% copper. NC18-09 also targeted down dip expansion and intersected 28.0 meters true thickness averaging 1.97% copper. The mineralization remains open. The Company intends to further delineate this new zone of high-grade mineralization.
  • Enhancing the Scale and Potential Economics of the Open Pit Project: As outlined in the recent PEA study, the Open Pit Project has the potential for robust economics and the option to expand in stages. Following the dissemination of the PEA technical report, the results of the 26 mineralized drill holes will be included in the resource model of the PFS study, expected Q1, 2019 with the potential to improve the grade and size of the resource estimate.         

 

 

Matt Gili, President and CEO, of Nevada Copper, commented, “We are very encouraged by this extensive set of drilling results, which includes the discovery of a new high-grade zone and new lenses of mineralization. We are also pleased to see the continued, strong progression of our waste-to-ore conversion program. Overall, the success of this program has the potential to improve the size and the economics of the open pit development at Pumpkin Hollow and we look forward to the PFS that is planned for Q1, 2019.”

The Importance of the Northern Extension Target Area: Located adjacent to and in the North Pit and covering an area of approximately 26 ha, the Northern Extension Zone was not previously drilled due to the now-completed land transfer process. As a result, the Northern Extension Zone was classified as waste rock or inferred material in the Existing Technical Report. Subsequent field work and analysis has shown the Northern Extension to be a highly-prospective area and the 2018 drilling included a waste-to-ore conversion program which has successfully intersected significant mineralization in this high priority target area.

 

 

What’s Upcoming: A new drilling program is expected in H1, 2019 as well as exploration to locate the source of the mineralization at Pumpkin Hollow In addition, a new PFS, encompassing the new drill holes and further expanding on the PEA results, is expected Q1, 2019. The underground mine is expected to commence production in Q4, 2019.

 

 

Further details on the Open Pit Project drill program, the Open Pit PEA and the underground mine can be found on the Company’s website www.nevadacopper.com.

 

 

QA/QC Information: The Company has a QA/QC program in place that monitors the chain-of-custody of samples and includes the insertion of blanks, duplicates, and certified reference standards within each batch of samples. Core is logged, photographed and split in half with one-half retained in a secured facility for verification purposes. Sample preparation (crushing and pulverizing) and analysis has been performed at American Assay Laboratories, Reno Nevada an ISO 17025 and NDEP accredited lab.

 

 

About Nevada Copper

 

Nevada Copper’s Pumpkin Hollow project is the only major, shovel-ready and fully-permitted copper project in North America. Located in Nevada, USA, Pumpkin Hollow has substantial reserves and resources including copper, gold and silver.

 

Its two fully-permitted projects include: the high-grade Pumpkin Hollow underground mine which is already under construction with a view to near-term commencement of copper production; and the Pumpkin Hollow open pit, a large-scale copper deposit which is currently undergoing an optimization program to target a reduced-capex, staged-development approach.
