A numerical study for a mining project using real options valuation under commodity price uncertainty

Sustainable Post-Mining Land Use: Are Closed Metal Mines Abandoned or Re-Used Space?

“…A notable part of new mining projects do not result from new discoveries but the re-evaluation of previously recognized mineralization or orebodies which become economic under changed technological or market conditions [3,53]. Indeed, many mines have been opened and reopened on several times.…”

“…A mine is closed when the resource is depleted or exhausted, or mining is no longer economically profitable due to a high cost of mining or low market prices [1][2][3]. Local communities in post-mining areas have traditionally faced challenges related to degraded landscapes, lowered environmental quality and socio-economic problems.…”

Eficiencia de los modelos Poisson y Logístico en la asignación de probabilidades de incumplimiento a empresas mineras mexicanas

“…Algunos autores como (Wise & Pozo, 2002), (Tetreault, 2013) para la minería o (Rodríguez -Núñez, 2015) para el petróleo aducen esta contracción del PIB a las diferentes reformas fiscales 2 como la de 2014 , mientras que otros como (Zhang, Nieto, & Kleit, 2015) o (Haque, Topal, & Lilford, 2014) hacen notar la relevancia de la baja generalizada en el precio de los metales en la contracción del PIB. Este entorno macroeconómico global provoca una disminución de la capacidad de las empresas del ramo para hacer frente a sus obligaciones crediticias, tal y como lo mencionan (Khan, Anuar, Choo, & Tahir, 2014) o (Maslyuk & Dharmaratna, 2013).…”

Integration of commodity price uncertainty in long-term open pit mine production planning by using an imperialist competitive algorithm

“…In contrast, commodity price is a variable where uncertainty arises from a number of factors and exact forecasting is not possible for future years. From an economic point of view, uncertain future commodity prices have a critical influence on mine project evaluation (Asad and Dimitrakopoulos, 2013;Haque, Topal, and Lilford, 2014). Open pit production planning under commodity price uncertainty may be effectively modelled as a stochastic integer programming (SIP) formulation with the objective of NPV maximization subject to a set of technical and operational constrains.…”
