Abstract:
In order to prepare mining plans, it is necessary to define assumptions, there are often uncertainties surrounding these assumptions that can have a short to long-term impact. Uncertainties related to potential future events and their consequences can lead to uncertain assumptions and thus make it difficult to guarantee that the decision taken presents an acceptable level of risk. Normally, when talking about planning assumptions, one refers to the geological model and/or performance of equipment, but here in this work the mining assumptions addressed go further, they are structuring assumptions such as: the activities necessary for pre-stripping a mine or the environmental licensing provision for the exploration of a new location. This article proposes the creation of a mine planning Project Management Office (PMO) to manage structuring assumptions for a mining business, which can cause impacts on production plans. As the quality of assumptions improves, the quality of results also improves, allowing us to make more assertive decisions and increase the value of mining resources. The implementation of a project office to manage assumptions seeks to create a planning environment where managers and technical staff, together with all stakeholders, understand the importance of management, and more than that, it provides a learning environment, with risk reduction and better result for the business.
