Mining companies that are developing projects and operating today are ensuring that mining operations are not only based on forecasting and minimizing operating costs and maximizing economic benefits over the life of the mine. Companies are also looking at the impacts of mining projects beyond the minimum requirements
Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified models that ignore the variability and uncertainty of these parameters. In this paper, two main sources of uncertainty are …

That's why, before starting mining projects or investing in the mining business, you need to make a proper mining business model or a financial plan to ensure accurate financial feasibility analysis, financial projections, forecasting, valuation, and other representations that will prove that the mining operation is profitable.
Gold Mine Closure and Decommissioning: 1 - 5 years. After a mine has ceased operations, possibly because the ore body is exhausted or the remaining deposit becomes unprofitable (uneconomic) to mine, work then focuses on its decommissioning, dismantling and rehabilitation of the land in which it was situated. Gold mine closure is a complex ...
