NCU Nevada Copper Corp

Nevada Copper (TSX: NCU) (OTC: NEVDF) (FSE: ZYTA) (“Nevada Copper” or the “Company”) is pleased to provide an update on restart and operational activities for its Pumpkin Hollow underground copper mine (the “Underground Mine”).

Randy Buffington, President & CEO of Nevada Copper, stated, “Our Pumpkin Hollow team is focused on advancing the restart project quickly and safely. We are building on the momentum of the recent achievements by the underground crews as they have progressed through the dike structure and are advancing into the EN Zone in anticipation of the underground development contractor arriving on site and commencing development. The technical and leadership teams are in place and committed to executing this restart plan. We are targeting a mill restart in the third quarter with a quick ramp up to nameplate capacity by the end of 2023.”

Production Restart Highlights

• Clear line of site to full-scale production
  • Simple and low-risk pathway to full-scale production established, comprising:
    • Phase 1 Q4 2022 to Q1 2023: Finalize dike crossings to access EN Zone initial stoping area (complete), confirm all key technical hires for restart (complete), and award capital projects contract (complete).
    • Phase 2 Q2 2023: Prioritized development of higher-grade EN Zone stope area.
    • Phase 3 Q3 to Q4 2023: Restart of proven mill, with surface and underground ore feed developed and short ramp-up to nameplate capacity.
• Phase 1 Restart Milestones Achieved
  • Development into the EN Zone has demonstrated that rock quality is consistent with our geotechnical model, which predicted competent ground within the EN Zone, and development is progressing at full round lengths and standard ground support.  
  • Definition drilling and assaying of all initial EN Zone stopes planned for extraction in 2023 is complete representing approximately 210K tons of stope ore, providing significant visibility on quality and grade of ore feed.
  • Contract awarded for completion of capital projects to debottleneck restart of development and underground operations.
  • Development mining contract award well progressed.
  • All key technical positions in place, with substantially strengthened operational leadership team on-site.
• Operations significantly de-risked
  • Completion of both critical dike headings, securing the Underground Mine with full access to the primary EN Zone stope area. The third dike crossing is progressing well and, while it is not required to meet 2023 operating objectives, is expected to be completed in the first half of 2023.
  • Building planned surface stockpile of approximately 150K tons of run-of-mine ore ahead of mill start-up provides substantial operating buffer for milling operations.
  • Debottlenecking capital projects front-ended to provide additional operating flexibility.

Further Details on Production Restart

Underground Development Proceeding as Planned

The Nevada Copper operations team continues to make rapid progress on all underground activities including mine development, hoisting, stope preparation, and underground projects.

The historically reported dike crossings that provide initial stope top and bottom access into the EN Zone were fully established and completed in December 2022, and development is progressing toward stoping areas. Both key development drives that have crossed the dike have encountered ground conditions at or better than expectation, confirming the geotechnical model that predicted higher quality rock. Definition drilling of the initial stopes to feed the restart of milling operations in Q3 2023 have been completed and assayed, and confirm rock quality, grade and geometry represented by the geologic and reserve models.  

Underground Development Contractor Update

The Company has completed the bid process for the development mining contractor and is in the final stages of negotiations for a unit rate contract with an internationally recognized major mining services contractor.

Key components of the development contract include:

• 72,000 feet of lateral capital development over a 24-month contract period;
• Delivery of full development stopes by Q3 2023 to provide sufficient faces and stopes to restart and maintain nameplate milling operations (approximately 5,000 tpd); and
• Nevada Copper’s operating team will perform all stope mining starting in Q3 2023.

Critical Construction Projects Progressing

The Company awarded Dumas Contracting USA, Inc. (“Dumas”) a $12 million construction contract to complete critical capital projects including the coarse ore bin and installation of an underground jaw crusher, permanent dewatering system, vent shaft stripping and surface fans. Dumas is a leading full-service underground mining contractor providing mine construction, development, production mining, mine services and engineering early-stage projects through well-established operating mines throughout the Americas.

Vent Shaft – Final stripping of the vent shaft commenced in January in preparation for connection of the surface fans, which are expected to be commissioned in early Q2 2023. The stripping is planned to be completed ahead of development contractor mobilization and the vent shaft is expected to provide the necessary ventilation for the life of the mine.  

Ore Handling System – The additional ore handling system allows for increased ore throughput rates to the shaft hoisting system, enabling operations to ultimately exceed nameplate production. Engineering for ore handling system has been completed, and all long-lead items are on-site including the jaw crusher. Excavation is underway and planning for the installation of the system has already commenced.  

Dewatering System – The pumps for the permanent dewatering system are on site and ready for installation. Once installed, the additional pumps are expected to provide all dewatering requirements for the life of the mine.

Regional Exploration Opportunities

The Company has completed a thorough review of regional mapping for its Pumpkin Hollow land position and several high-quality targets of interest have been identified. Surface sampling results from the Copper Ridge area have indicated the high-grade potential, highlighted by grades including 5.03% and 5.43% copper (see table below for additional assay information) that warrant additional investigation. In 2023, detailed mapping, interpretation of recent geophysical analysis and surface sampling are planned to follow-up on other identified high-potential targets on the Nevada Copper land position. The grades identified are conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the delineation of a mineral resource. Grades were determined through third-party labs, as detailed below under “Quality Assurance and Quality Control”.
