Faced with fluctuating demand, cyclical pricing and a decrease in the profitability of the mining industry, operating an efficient and streamlined business is critical to any mining operation. Thus, despite its inherent complexities mining firms have been integrating the lean principles of the manufacturing industry into their own operations.

Rooted in the automotive industry and derived from the Toyota Production System, lean best practice has over the past 30 years been applied to great effect in almost every facet of the manufacturing sector. And it is now, with the ever-increasing pressure on the bottom line, that mining firms are looking to reap the rewards of lean processes.

In recent years, some of the most industries most influential executives have spoken out about the benefits of lean and similar continuous improvement strategies. In 2008, Rio Tinto’s CEO Sam Walsh gave a speech stating Six Sigma “is a very fundamental change in the way that we structure our work, actively engaging, actively involving, actively communicating with our people.

“It's not the senior management that implement the sort of significant improvement on the ground it's actually every single person working within Rio Tinto.”

It is fair to suggest that initiatives to come out of business improvement programs include minimised shutdowns, increased production and increased chances of reaching annual targets. 

Clearly, there are plenty of various opportunities for mining companies to benefit from lean best practice, however implementation will not always yield immediate results. The important fact to remember when putting these business improvement processes in place is that they do not come overnight and successful implementation requires the participation of the whole organisation.

But why should the mining industry adopt lean principles into their business process? How can they do this effectively?

A study conducted, titled ‘Implementing Lean Principles in Mining Industry Issues and Challenges’ states that lean processes can significantly help mining companies eliminate waste and improve processes because of a shared common view with the automotive sector. According to the study >>>

  • Both rely if effective business processes;
  • Both rely on efficiency within the value stream;
  • Both strive to maximise operational efficiency;
  • Both rely on an extensive supply chain;
  • Both sectors have a ruthless focus on safety.

These similarities bring an opportunity to successfully apply lean principles into the mining industry.

Why and how should mining companies incorporate lean into their business processes and what benefit will it bring to the industry?

1. Identify value

Critically, the starting point for lean thinking is value. Think of it like this: everything that doesn’t add value to the end product is waste and your customer is not willing to pay for it. Waste needs to be eliminated to make value flow. There are seven types of commonly identified waste >>>

  1. Waiting
  2. Over production
  3. Repair
  4. Motion
  5. Processing
  6. Inventory
  7. Transportation

Strive to eliminate these forms of waste from your value chain.

2. Map your value stream and update it

Your value stream is the entire business process from thought to completion; it’s the end-to-end process that ultimately delivers value to your customer. In order to make your mine lean it’s important to map every single process (no matter how small or seemingly insignificant) and streamline it. Waste can be easily identified this way and removed from the process, saving you precious time and money. Once again this needs to be a continuously reviewed process.

3. Empower your employees
Lean is the ceaseless elimination of waste and therefore effective implementation relies heavily on the engagement not only of workplace leaders, but of individual employees as well. In order to achieve success its important to ask employees to set agreed standards for their work and empower them to improve their own standards continuously.

Although it can be a tough change to make, managers need to allow personnel on the shop floor to solve problems and make operational decisions. After all those on the ground will be far better placed to make suggestions and waste elimination and process improvement. A mining manager’s role should be that of a mentor, who will provide the necessary tools and resources for continuous improvement. In order to make this a successful as possible, mining companies should consider educating its people about effective problem solving. 

As part of empowering your employees, its vital you provide a visual representation of key product performance date, which will empower employees even at the lowest level to make operational decisions based on data and key findings.

It is important for mining companies to delve deep into their operations if lean is going to be successful. For example, down time and repairs on vehicles needs to be monitored and scheduled effectively for minimal impact. Companies also need to be aware that human talent holds 70 percent of the improvement potential within the mining industry, so a large emphasis needs to be placed on training and employee empowerment.

There are some elements of a mine that cannot be controlled, making lean processes harder to implement. Take as an example a manufacturing plant – rules such as 5S and visual factory can be well executed – meaning cleanliness, organisation and accessibility of the workplace can be easily organised. This is much more of a challenge in the mining industry and will take a lot more time to organise.

Lean principles have the potential to be successfully applied in the mining industry, however there are challenges that need to be considered and overcome. Think of lean not just as a change of process but also a change in company culture. It is a slow process and one that will require total devotion. Applied correctly, lean principles could have some seriously positive impacts on your business.

“With the acquisition of GT Gold and the Tatogga project in the highly sought-after Golden Triangle district of British Columbia, Canada, Newmont continues to strengthen our world-class portfolio,” commented Newmont President and CEO Tom Palmer.

“We look forward to continuing to build a respectful and meaningful relationship with the Tahltan Nation, including the community of Iskut. The relationships we have with Indigenous communities, First Nations and host communities are critical to the way we operate. We will partner with the Tahltan Nation at all levels, and with the Government of British Columbia to ensure a shared path forward as the Company understands and acknowledges that Tahltan consent is necessary for advancing the Tatogga project.”



Newmont’s acquisition includes the Tatogga project, comprised primarily of the Saddle North deposit, which has the potential to contribute future significant gold and copper annual production. There are also further exploration opportunities beyond the known deposits at Saddle North within the land package. The Tatogga project adds to Newmont’s existing interest in the prospective Golden Triangle through the company’s 50% ownership in the Galore Creek project.

Newmont is the world’s leading gold company and a producer of copper, silver, zinc and lead. A world-class portfolio of assets, prospects and talent is anchored in favourable mining jurisdictions in North America, South America, Australia and Africa. The American miner is celebrating its 100th anniversary this month.


With gold prices on the rise, the last six months has seen gold industry M&A activity accelerating. A recent Mckinsey report, advises that the industry need to be mindful of mistakes made during the previous gold price boom, when growth was chased unidirectionally by several companies.
