Mines restarting


The process involved with restarting a mine is not one to be taken lightly, involving intricate planning, substantial investments, and a commitment to sustainable practices. As the global demand for essential minerals and resources continues to rise, the restarting of mines currently in care and administration or remission presents a compelling opportunity for mining companies. However, the journey to revitalize a mine is a complex one, requiring meticulous planning and a deep understanding of the intricacies involved. 

In this article we aim to provide mining industry professionals with the knowledge, insights, and solutions needed to navigate the challenges and seize the opportunities that come with mine restarts. This guide delves into the critical considerations and methodologies that underpin successful mine restarts. From conducting thorough due diligence, assessing the economic viability, and securing the necessary permits to embracing technological innovations and fostering a commitment to environmental stewardship, this guide will serve as your compass for charting a successful course.

The benefits of restarting a mine.


Restarting a mine offers a range of advantages, making it a strategic choice for mining operators: 

  1. Job Creation and Economic Growth: A mine restart leads to the reemployment of skilled labour, boosting local economies and providing job opportunities. New jobs mean increased income, which, in turn, stimulates consumer spending in the region. 
  1. Resource Recovery: Restarting a mine allows for the recovery of valuable resources that may have become economically viable once again due to changes in market demand, technology, or commodity prices. This resource recovery can have a significant impact on the mining operation’s profitability. 
  1. LOM Extension: Reopening a mine extends its Life of Mine (LOM), potentially adding years or even decades of production. This strategic advantage ensures a consistent supply of raw materials in the long term. 
  1. Targeting Proven Deposits in Safe Jurisdictions: Restarting a mine enables operators to focus on known, proven deposits in regions with established safety records. This minimises exploration risks and enhances the likelihood of successful extraction. 
  1. Leveraging Existing Infrastructure: Existing infrastructure, such as roads, rail, and processing facilities, can be utilised, reducing capital expenditure and accelerating the restart process. 
  1. Reuse of Approved Permits and Licenses: In some cases, previously approved permits and licenses can be reactivated, streamlining the regulatory process and saving time and resources. 
  1. Minimising Operating Expenses: Restarting a mine often involves lower initial capital expenditures compared to developing a new mine from scratch. This cost efficiency can result in reduced operating expenses. 
  1. Faster Achievement of Objectives: Restarting a mine can help operators achieve their production and financial objectives sooner than opening a new mine. With the groundwork already in place, operations can commence relatively quickly. 

These benefits collectively make mine restarts an attractive option for mining operators, offering the potential for economic growth, resource recovery, and the achievement of operational objectives in a timely and cost-effective manner. 


Care and maintenance


Steps to restart a mine. 


Due diligence and feasibility study.


Before committing to a mine restart, it is crucial to understand why the mine was initially shut down. A feasibility study should be conducted to assess the economic viability and technical feasibility of reopening the mine. 


Securing finance.


Securing the necessary capital for the restart is essential. This can involve seeking funding from various sources, including investors, banks, or government grants. 


Regulatory and permitting compliance.


Restarting a mine requires compliance with various regulatory and permitting requirements. It is important to navigate the approval process and obtain the necessary permits from relevant authorities.


Infrastructure and equipment assessment.


Assess the condition of existing infrastructure, mining equipment, and processing facilities. Upgrades or replacements may be needed to optimise operations. 


Minetek Power can help.
