I’m sorry, but I’m not sure what you are asking. Could you please provide more information or clarify your question? If you are looking for information on mine value chain analysis, I found an article by McKinsey that provides a comprehensive overview of the mining value chain. The article explains how companies that manage their value chain well can establish a significant source of competitive advantage and value creation. It also highlights the bottlenecks and constraints that companies may encounter if they neglect their value chain. The article further discusses how recent shifts in commodity markets, environmental concerns, and new regulatory policies have put pressure on mining companies to increase resilience, flexibility, and productivity to remain competitive. The article concludes by illustrating how creating transparency to improve decision making and keeping the right tools at hand can help mining companies prepare for an increasingly volatile future.
