Is geological sophistication silently killing practical mine planning? Over the last two decades, geological modeling has undergone a revolution, albeit not a flashy one. What once required painstaking work using cross-sections and block models is now possible using implicit modeling engines, stochastic simulations, and machine learning-based lithological interpretation tools. As the capabilities of these programs increase, the question we must pose is: are we building models for the mine, or models for conferences?

What are the differences between greenfield and brownfield exploration? In the context of mineral and energy resource exploration, greenfield and brownfield represent two fundamentally different search environments that offer different opportunities and risks and require different methodologies. Greenfield exploration is focused on areas of the Earth’s surface where no known deposits of minerals or previous commercial development have occurred.

Types of backfill in underground mining Backfilling is an essential engineering practice in underground mining with the objective of stabilizing mined-out voids, also known as stopes, with the ultimate goal of improving ground control and environmental sustainability (Feng et al., 2023). The contemporary methods of backfilling can be grouped into three main types based on the composition and application approach, which include rock backfill, hydraulic backfill, and paste backfill (Oke & Hashemi, 2021).

What is the real value of responsible mining? The question of whether "responsible mining" represents a paradigm shift or merely a sophisticated form of branding remains a key issue in current research on the extractive industries. While the extractive industries themselves claim such initiatives to be indispensable to the energy transition to green energy, observable phenomena in the immediate surroundings reveal a disconnect between the rhetoric and the reality of their operation.

What are the key differences between kinematic, limit equilibrium, and numerical slope stability analyses in mining? Methods of slope stability evaluation have varying complexities and data requirements. Kinematic methods are screening techniques that provide information on the structural feasibility of certain failure modes based solely on geometric data. Although it does not provide factors of safety, it is a highly useful technique for the initial evaluation of potential planar, wedge, or toppling failures.

What maximum longitudinal gradients are acceptable for different classes of haul trucks? In the complex environment of open-pit mining and heavy industrial transport, the design of haul roads is a critical determinant of operational efficiency, safety, and cost-effectiveness. Among the various design parameters, the longitudinal gradient, the slope along the direction of travel, stands as one of the most influential.

Flexibility drives long-term plant profitability. For years, fixed plant design in mining, including crushers, mills, and processing systems, was all about one thing: maximizing capacity. Increasing capacity meant increasing production, lowering unit costs, and hence better economics. But the rules of the game are rapidly changing. The question is no longer about maximizing capacity in fixed plant design in mining. The question is, should flexibility be prioritized in fixed plant design in mining?

What is the difference between GPS and GNSS in mining? The key difference between GPS and GNSS in mining is that GPS refers to a single satellite system, while GNSS includes all global satellite constellations. GPS is the U.S. navigation system with about 24 satellites, whereas GNSS combines GPS, GLONASS, Galileo, BeiDou, and others. Because GNSS receivers use signals from multiple systems, they offer better accuracy, reliability, and coverage especially in challenging mining environments or areas with limited GPS visibility.

Chile, US eye collaboration on rare earths and other critical minerals Chile and the U.S. have signed a joint statement to begin discussions on rare earths and other types of critical minerals, Chile's foreign ministry said on Thursday. The first meeting will take place within the next two weeks, it added. Areas of potential coordination include public and private financing for mining projects, the management of scrap for minerals recycling, and exploration for new projects that could help boost minerals supplies in both countries.

India's Jindal Stainless flags operations disruption due to fuel shortage. India's Jindal Stainless on Friday said that its plants were operating at a reduced capacity because ​of fuel shortages in the wake of ‌disruptions from the Middle East war. “Due to the heavy dependence of stainless steel manufacturing on industrial gases such as ​propane/ LPG and natural gas, several processes across ​our plants have been adversely impacted," the company ⁠said in an exchange filing. India's crude oil, LPG, and ​liquefied natural gas (LNG) supplies have been disrupted due ​to shipping constraints after the U.S. and Israel's war with Iran halted traffic through the Strait of Hormuz, compelling India to ​scramble for alternatives such as buying more from Russia. Authorities have ​also diverted gas supplies from industry to prioritize household consumption.
