Strategic Pumpkin Hollow Mine Restart to Boost US Copper Supply

Revitalizing Pumpkin Hollow: Strategic Copper Mine Restart Plan

The restart pumpkin hollow mine represents a pivotal development in domestic copper production, with Kinterra Capital Corp securing $80 million in strategic equity financing led by Lionhead. This Nevada-based asset, equipped with over $800 million in installed infrastructure, stands poised to address growing copper demand across critical American industries. The restart leverages existing development while implementing strategic improvements to create a sustainable, efficient production facility capable of delivering results within a compressed timeline.

Current Status and Strategic Importance

The Pumpkin Hollow underground mine presents a uniquely positioned opportunity in the domestic mining landscape. As a fully permitted operation with zero debt or stream obligations, the project offers exceptional financial flexibility compared to other mining developments. The underground resource contains approximately 1.7 billion pounds of copper, with production targeted to begin within 24 months of the October 2025 announcement.

This timeline positions Pumpkin Hollow as one of the fastest-to-market copper sources in the United States, a critical consideration as demand for domestically sourced materials intensifies across manufacturing and energy sectors. The established infrastructure significantly reduces capital requirements and accelerates the path to production.

Why is the Pumpkin Hollow Restart Significant for US Copper Supply?

The revitalization of Pumpkin Hollow arrives at a watershed moment for American industrial strategy. Copper, once considered simply another industrial metal, has transformed into a strategic resource underpinning energy transition and security, technological advancement, and national security objectives.

Strategic Copper Supply for Critical Industries

The combined production potential between the underground mine and adjacent Southwest Open Pit project could generate approximately 228 million pounds of copper annually, representing 5-6% of current US copper demand. This production capacity positions Pumpkin Hollow as a strategically important asset across multiple sectors:

• Energy Transition Infrastructure: Power grid modernization, renewable energy systems, and energy storage all require significant copper inputs
• Advanced Manufacturing: From electric vehicles to high-efficiency motors, copper remains essential for next-generation manufacturing
• AI and Computing Infrastructure: Data centers and advanced computing facilities rely heavily on copper for power delivery and thermal management
• Defense Applications: Military systems demand reliable, domestically-sourced materials for critical components

Domestic Supply Chain Resilience

American industry currently faces significant exposure to international supply disruptions. Approximately 35% of US copper demand is met through imports, creating vulnerability to geopolitical tensions, transportation disruptions, and market manipulation. The restart pumpkin hollow mine directly addresses this challenge by providing a secure domestic supply source.

Unlike greenfield mining projects that might require 7-10 years to reach production, Pumpkin Hollow's accelerated 24-month timeline delivers much-needed supply resilience on a compressed schedule. This rapid deployment capability makes the project uniquely valuable within the national critical minerals strategy.

How Will the Restart Plan Be Implemented?

The restart strategy centers on methodical planning and execution to ensure long-term operational success. Rather than rushing to production, Kinterra and Lionhead are implementing a comprehensive technical approach that addresses previous operational challenges while incorporating modern mine planning practices.

Technical Approach to Mine Revitalization

The restart methodology follows a structured process designed to optimize outcomes:

• Comprehensive Gap Analysis: Systematic evaluation of existing infrastructure, identifying areas requiring rehabilitation or upgrade
• Data-Driven Decision Making: Extensive collection of geological, metallurgical, and operational data to inform optimization decisions
• Engineering Trade-Off Studies: Systematic evaluation of alternative approaches to maximize economic returns while ensuring operational resilience
• Industry-Standard Engineering: Advanced technical work across mining, processing, and infrastructure disciplines to ensure best practices

This methodical approach reflects lessons learned from previous restart attempts at other mining operations, where rushed timelines often led to suboptimal performance. By investing in proper planning and engineering, the restart pumpkin hollow mine aims to avoid common pitfalls.

Phased Implementation Timeline

The project follows a structured timeline designed to systematically advance toward production:

1. Assessment Phase (Q4 2025): Detailed technical evaluation and planning
2. Infrastructure Rehabilitation (Q1-Q2 2026): Upgrades to critical systems including dewatering, ventilation, and power distribution
3. Underground Development (Q2-Q3 2026): Re-establishing access and preparing initial production areas
4. System Testing (Q3-Q4 2026): Commissioning of processing facilities and operational systems
5. Production Ramp-Up (Q4 2026-Q2 2027): Systematic increase to full production capacity

This phased approach allows for testing and validation at each stage, reducing operational risk and ensuring sustainable performance when full production begins.
