Nevada Copper Announces Q1-2018 Drill Program and Open Pit Optimization and Development Plan

VANCOUVER, British Columbia, Nov. 28, 2017 (GLOBE NEWSWIRE) -- Nevada Copper Corp. (TSX:NCU) (“Nevada Copper” or the “Company”) is pleased to announce its resource extension drilling plan for Q1-2018 and provide an update on its 100% owned Pumpkin Hollow Project for 2018, including both the Underground Project and Open Pit Project development plans for 2018.

Highlights of 2018 Development Plan

• Restart of Underground Project construction: Following the previously announced Underground Project Pre-Feasibility Study for Pumpkin Hollow, Nevada Copper is moving swiftly towards the re-commencement of project construction with further project updates to follow over the coming months, including:
  • Management and project team additions;
  • Engagement of project consultants to complete basic and detailed engineering to facilitate a construction decision;
  • Procurement of long lead items and engagement of mining contractor; and
  • Project financing.
    
• Commencement of Open Pit Project resource extension drilling: A key value driver for Nevada Copper is the further delineation of previously undrilled extensions to the Open Pit Project resources (Figure 1. below):
  • Drilling to commence early Q1 2018, with an initial low-cost 10,000 meter program that will be increased on a success basis focused on specific high-potential resource extension zones in the North deposit;
  • Drilling completed subsequent to the 2015 Integrated Project Feasibility Study, contained mineralization in zones currently not included in the Open Pit project economics;
  • Additional well defined, low-risk targets were not previously drilled due to the now-completed land swap and project permitting process; and
  • Potential to convert material currently classified as waste into resources and minable inventory. A quarter of the currently defined higher-grade North pit remains untested.
    
• Open Pit Optimization: Significant scope identified to improve Open Pit Project economics, reducing pre-production capital and increasing the project’s Internal Rate of Return, in line with the Company’s focus on near-term production and a philosophy of “margin-over-tons”, including:
  • Extensional drilling with the aim to convert “stripping waste” into payable ore;
  • Re-costing of project inputs to reflect the current low point in the mining capex cycle;
  • A smaller start-up option focused on the higher-grade North deposit; and
  • Target to re-define Open Pit Project economics during 2018, with a view to near-term project development.

Restart of Underground Project Construction

As announced on November 20, 2017, the Company is proceeding to complete and SEDAR-file a Technical Report (“Technical Report”) that discloses a new 5,000 tons/day underground mine development option (“Underground Project”). The Company is moving towards a project financing package which will involve our largest shareholder, new investors and its senior lender. Completion of the project financing package will allow for a construction decision by Q2-2018 leading to first production in 2019. Nevada Copper will provide a further update as details are finalized.

In early 2018, the Company plans to execute an EPC contract for the process plant, and start assembling its construction execution, operation and mine build team.

Commencement of Open Pit Project Resource Extension Drilling
As a result of its higher grade and untested zones, the North deposit of the Open Pit Project, offers significant scope for value creation.

The Mineral Reserves¹ for the North deposit at 300 million tons has a grade of 0.445% (0.471% Cu-equiv.²), approximately 39% higher than the South deposit average. Further, the planned mill feed grades from the North deposit in the first four years of production are 0.56% Cu (0.60% Cu-equiv.). This is within a total open pit Mineral Reserve of 539 million tons grading 0.39% copper³.

Until the acquisition of the Federal land had been completed in late 2015, Nevada Copper had deferred any drilling on the lands across the northern boundary of its patented claims, land beneath which we believe are extensions of the North deposit. With this land now wholly-owned, the Company is free to test for the northern extension of the North deposit without the need for Federal permits. Nevada Copper considers that the North deposit has excellent potential for resource expansion to the north and to the west. If successful, drilling along with technical studies also has the potential to convert material classified as waste into ore in areas that have not been drilled historically.

2018 Drill Program
In order to test the North deposit extensions and support a new 2018 mineral resource for the North deposit, an initial 10,000 meter (33,000 foot) drill program is planned with an initial budget of $2.5 million. This budget will be increased on a success basis and will be followed by an updated Mineral Resource which will lead to a future feasibility study to evaluate a smaller North Deposit open pit development, as described above. Drilling is expected to start in early Q1-2018 and will be subject to completion of a financing package discussed above.

North Deposit: Northern Extension (“Northern Extension”)
The figures below demonstrate the importance of drilling the Northern Extension for both resource and pit design. Approximately a quarter of the North pit does not have any drilling. Extending and intersecting mineralization within these areas will add to mineral resources while reducing waste tonnages.

Drill results in 2015 from the center of the North pit demonstrated that additional drilling could have a considerable influence on converting waste into mineral resources in the core of the deposit. Several holes in the center of the North deposit including NC15-16, all intersected multiple zones of mineralization. The upper zones correlated well or enhanced existing mineralization. The new lower zones help fill in areas where drill density is limited and the rock is currently classified as waste or inferred. This is an area that would benefit from additional drilling.

Below is a cross section (Figure 2) that includes drill-hole NC15-16, and shows how the mineralization intersected in that hole has been expanded (red dash). In NC15-16 intersected a much larger shallow high-grade zone than the adjacent holes, 126.0 feet true thickness grading 1.29% Cu. Expanding this area will have a positive effect on the copper grades in the early years of production from the North deposit.

North Deposit: Connector Zone Drilling
The Connector Zone refers to the “saddle area” between the North and South deposits. Like the Northern Extension, parts of the Connector Zone were affected by the land acquisition process which restricted the ability to follow up very promising drill results such as NC12-03 below. With this land now wholly-owned, the Company is free to test all areas of the Connector Zone.

Connector Zone drilling in 2012 encountered substantial widths of high grade copper mineralization that was followed up with drilling in 2015. An example was drill-hole NC12-03 located along the North deposit's south border which intersected high grade mineralization on the edge of the open pit limits, NC12-03 intersected 122.7 feet (37.4 meters) true thickness grading 3.96% copper, 0.384 grams/tonne gold, and 14.2 grams/tonne silver.

In 2015, NC15-13 drilled on the bridge of the pits intersected shallow mineralization 63.9 meters (209.5 feet @ 1.39% Cu), true thickness (Figure 3). Just northwest of NC15-13, drill hole NC15-03 intersected over 42.8 meters (158.0 feet @ 0.79% Cu), true thickness. Some of these holes lie outside the ultimate pit designs.

With the holes already drilled, together with any follow-up drilling success and additional engineering studies, the configuration of the pit design on the southern edges would likely change and add mineral resources while reducing waste tonnages.

As part of the optimization of a North deposit mine development plan, the information from Connector Zone drilling would be continued and incorporated into a new mineral resource along with new information from North Extension drilling.

Open Pit Development Optimization
In 2018, parallel to the advancement of the Underground Project, Nevada Copper will continue to evaluate opportunities to significantly improve the economics of the Open Pit Project.

Phillip Day, Chief Operating Officer of Nevada Copper, commented: “We believe there is significant scope to optimize the development scale of the Open Pit Project by right-sizing production rates and focusing on lower initial capital costs, with mill feed sourced from the higher-grade North deposit. This is a further application of our “Margin-over-Tons” operating philosophy. These opportunities are further enhanced by the potential to reduce assumed waste stripping volumes as a result of the drill program targeting the Northern and Connector Extensions zone to expand and follow-up the known areas of potential high-grade mineralization.”

Investigation of these optimization opportunities commenced in 2016 and, moving into 2018, Nevada Copper will focus on demonstrating specific opportunities and defining an optimized development plan in more detail including:

• Define smaller start-up option:
  • Restricting initial operations to the higher-grade North deposit; and
  • Resize project scale appropriately to lower capital costs with a possible production rate range of 30-40,000 tpd (versus the existing 70,000 tpd assumed in the 2015 Integrated Feasibility Study).
    
• Update capital and operating costs to reflect current cost environment:
  • Initial reviews undertaken indicate opportunities to realize savings as a result of re-quoting key capital items in the current lower cost environment.
    
• Re-commence drilling on the North deposit and refine pit design:
  • Test the northern and western extensions of the North deposit;
  • Extend the area of known high-grade mineralization in the Connector zone on the southern limit of the current pit design; and
  • Combining drill results with ongoing technical studies has the potential of converting material currently classified as waste into ore. The resultant increase in tons and reduction in waste stripping requirements could significantly improve project economics.

Giulio Bonifacio, President & CEO of the Company commented: "With the Underground Project set to proceed, we are working in parallel on the optimization of a western area open pit mine development following the same philosophy applied in the recently-completed high-grade Underground Project optimization. Drilling to extend North deposit resources and a re-scaled open pit development, represents a tremendous opportunity to add further value to Pumpkin Hollow and, equally exciting, such a larger development is allowed within our current permits.

Pumpkin Hollow is a truly unique, robust base metal asset that is fully-permitted in a top-tier location with built-in growth potential and upside both by way of the underground development plan and the large open pit deposits and proposed development plan which will be further advanced in 2018.”
