Global economic and population growth, preference of consumers, policy and so forth are the several factors that are influencing the growing demand of metals and other minerals (Langkau & Tercero Espinoza, 2018) (Hodgkinson & Smith, 2018). For example, to achieve the target (zero carbon emissions (Hodgkinson & Smith, 2018)) for manufacturing renewable energy or technologies that are energy efficient by 2050, the global production of aluminium and copper should have a 5-18% cumulative annual increase (Deng, Chang, Yeh, Cheng, & Kuo, 2011). Similarly, the increasing popularity and demand for electric vehicles will also require an increase in the production of various types of metals (Ni, Li and so on). To keep up with this growing demand, extraction of mineral deposits in beyond norm conditions is becoming an emerging reality. However, depth and location (e.g. remote and/or underwater) of these deposits associated with the stringent, restrictive obligation on carbon emissions and other pollutants are the biggest challenges towards this quest. The remoteness of the locations does not make it feasible for these mines to be connected with the grid.In most cases, this makes these mines utterly dependent on their own for their colossal power demand. To deal with this issue, mining, as an energy-intensive industry, feels the necessity to come up with a sustainable roadmap of powering these remote mines. Offering the status quo of the mining sectors energy portfolio, this study discusses the implementation of various technologies that can make the entire strategy of powering up the remote mines more sustainable. Categorizing three different mine energy roadmaps based on the utilization of conventional, contemporary and futuristic technologies, the required pace and momentum for transitioning from one road to another has been canvassed.
