Introduction

Our firm was engaged in conducting a comprehensive logistics study for a North American mining operation planning to transport raw nickel ore and pre-concentrate it from Minnesota to Michigan. The client needed to understand the most cost-effective and reliable transportation options to move approximately 800,000 tons annually beginning in 2025. With multiple potential modal combinations—including rail, truck, vessel, and various transloading scenarios—the consulting team was tasked with analyzing transportation costs and infrastructure requirements to determine the optimal logistics solution. This complex multi-modal assessment required deep expertise in mining supply chains and transportation economics to develop a 20-25% cost estimate accuracy for long-term planning.

At A Glance

Our team of supply chain experts delivered a comprehensive modal analysis that identified the most cost-effective and logistically viable solutions for transporting critical mining materials across a complex supply chain network. The analysis provided the client with actionable intelligence to support their long-term investment decisions.

Requirements:

  • Analyze cost and feasibility of multiple transport modes (rail, truck, vessel) and combinations for moving nickel ore and pre-concentrate between mining and processing sites
  • Provide high-level transportation cost analysis at ±20-25% accuracy for projected 2025 operations
  • Evaluate trade-offs between railroad-controlled equipment versus private equipment options

The Challenge

The client faced significant logistical challenges in developing a reliable and cost-effective supply chain for their new mining operation. With approximately 800,000 tons of material to transport annually between distant sites, they needed to evaluate multiple transportation options across different modes. Each option presented unique considerations:

  • The most direct route required 582 miles of circuitous rail transport, doubling the actual geographic distance and increasing costs.
  • Vessel transportation options offered potential cost savings, but they presented seasonal limitations, with winter ice closures requiring inventory buildup.
  • All options required varying levels of infrastructure investment at both the origin and destination.
  • Railroad carriers declined to provide equipment, necessitating the evaluation of private leasing options.
  • Terminal locations and handling capabilities were limited, with key stakeholders unwilling to provide services.
  • Multiple transportation providers needed to be coordinated across the supply chain.
  • Long-term inflation and cost escalation factors must be accounted for in the 2025 planning horizon.

These challenges required sophisticated modeling of 22 different routing options to determine which would provide the optimal balance of cost, reliability, and operational flexibility.

PraxiChain Solution

Our team’s comprehensive modal analysis solution included:

  • Detailed assessment of 22 distinct transportation routing options, with complete cost modeling for 19 viable scenarios
  • Engagement with 17+ transportation service providers, including Class I railroads, short line carriers, vessel operators, terminal operators, and trucking companies
  • Development of a sophisticated methodology to calculate unit transportation costs for direct rail and multimodal alternatives
  • Side-by-side comparison of equipment options, including private vs. railroad-controlled equipment scenarios
  • Evaluation of infrastructure requirements for each modal option
  • Analysis of rail cost adjustment factors to forecast 2025 transportation costs
  • Identification of potential funding programs to offset infrastructure investment requirements

Results

The analysis revealed that six of the lowest-cost options involved rail transportation, with the optimal solution offering a 30% cost reduction compared to the median scenario. The study provided crucial insights into modal trade-offs:

  • While rail-vessel-truck offered the lowest absolute transportation cost at $32.37 per ton, this option required multiple handling touchpoints and faced seasonal constraints.
  • Direct rail transport ($35.88 per ton) provided greater operational flexibility, minimized handling points, and reduced inventory carrying costs.
  • Infrastructure investment requirements varied significantly by modal option, with some requiring minimal origin investment but higher ongoing operational complexity.

The client gained a clear understanding of the cost-benefit analysis for each option, including capital investment requirements, operational considerations, and long-term cost projections. Our expert’s recommendations allowed the client to confidently pursue service provider negotiations, leveraging the comprehensive data to secure favorable rates. Most significantly, the analysis revealed several alternatives offered similar economics, providing the client strategic flexibility in their infrastructure investments and partner selection. This flexible approach strengthened their negotiating position and reduced long-term supply chain risk.
