YERINGTON, Nev., Dec. 09, 2021 (GLOBE NEWSWIRE) -- Nevada Copper Corp. (TSX: NCU) (OTC: NEVDF)(FSE: ZYTA) (“Nevada Copper” or the “Company”) today provided an operations update and overview of the H2 2021 milestones achieved at its underground mine at the Company’s Pumpkin Hollow Project (the “Underground Mine”).
The Company has experienced a significant reset and demonstrated significant operational and corporate improvements in H2 2021. These milestones provide a foundation for an accelerating pace of operational ramp-up.
“I am very pleased with the progress the Company has made in H2 of this year,” stated Randy Buffington, President and Chief Executive Officer. “Our mining rates, a key metric for ramp-up production advancement, have been increasing month over month. We are now seeing the efficiencies generated from the advanced management systems implemented in Q3 of this year. The building blocks are in place for increased mining rates and production as we move into H1 of next year.”
Operations
Equipment availabilities materially improved: 14% improvement from 65% to 74% in total fleet availability since the beginning of Q4, 2021. Additional equipment expected to be added in Q4, 2021.
Contractor performance improved: Productivity increased by 31% from 1.75 to 2.29ft per person shift between October and November resulting in substantial improvement in operating efficiency as well as cost reductions.
Increased mining development rates: Sequential monthly increases in development rates, a key leading indicator of production ramp-up, delivered since management changes in August 2021. Rates achieved in December are currently 50% higher than August. Commissioning of additional bolters planned to deliver a further 50% increase in development rates in the coming weeks.
Consistent mill performance: Milling operations have performed well throughout 2021, with batch processing reaching 4700tpd, recoveries over 90% and concentrate quality performing in-line with design specifications.
Dike crossing completion: First crossing of the water bearing dike was completed in August 2021, and the second crossing is anticipated to occur later this year. No further crossings are required during the ramp up to 3ktpd expected in H1, 2022.
Ventilation infrastructure in place: All underground ventilation infrastructure was completed in H1 2021. Final addition of surface ventilation fans remains on schedule, with commissioning planned to be completed in January, 2022, with ventilation no longer expected to be a constraint to production rates thereafter.
Corporate
Transformational financing completed:
Closed C$125m public equity offering in November 2021, with a significant portion of the funds provided by select mining sector corporates. This was further complemented by broad participation from other new and existing institutional investors.
The upsized financing provides additional liquidity to fund exploration and expansion studies at the Company’s open pit project (the “Open Pit Project”) in addition to the ramp-up of Underground Mine.
Significantly enhanced balance sheet flexibility:
Long term debt reduced by approximately 30% during Q4, 2021.
First debt repayment under the Company’s senior credit facility with KfW-IPEX Bank deferred by 2 years to July 2024.
Hiring of key management positions:
Joining as Chief Executive Officer on October 6, 2021, Randy Buffington brings substantial operational and development experience in both underground and open pit mines in Nevada and internationally.
8 key operational management positions added in H2 2021, resulting in operational improvement and enhanced planning and execution systems.
Development
Developed program for Open Pit Project resource extension and feasibility study: The budget and execution plan have been defined and the Company expects that drilling to support the updated open pit feasibility study will commence in Q2 2022, potentially sooner depending on drill rig availability.
Open Pit Project Decarbonization Program Advanced:
Solar power studies were completed in 2021, which show:
Pumpkin Hollow benefits from ample sun and land to support a large solar project with the capacity to meet a significant portion of the Open Pit Project’s power requirements;
The solar potential at the site is up to 200MW;
The already low grid power costs in Nevada could be further reduced through an on-site solar plant; and
A third-party solar project provides an option to remove upfront power infrastructure costs from the Open Pit Project.
Electric fleet study for mobile mining equipment fleet electrification at the Open Pit Project was completed by US-based energy and sustainability consultant Sprout Energy, which concluded:
Scope 1 carbon emissions over the life of mine could be reduced by approximately 10% of total estimated emissions; and
Fuel and maintenance costs could be reduced by up to approximately US$200m over the life of mine.
Exploration
Undertook further property reconnaissance on the Copper Ridge Area, which is located to the northeast of the Open Pit.
Defined target exploration plan: Initiated further refinement and interpretation of the newer geophysics in key areas such as Tedeboy, Tedeboy porphyry and Copper Ridge.
Initial grab sampling and mapping of these areas have resulted in areas with high grade copper samples. Surface mapping and sampling are planned for Q1 of 2022, supporting the commencement of drilling in Q2 2022.
