Understanding Strip Ratio in Surface Mining Introduction In open-pit mining, one of the most fundamental concepts determining the viability and cost-effectiveness of a project is the strip ratio. It is a vital metric that informs whether it is economically feasible to mine a specific deposit. This article explores what the strip ratio is, how it’s […] Table of Contents Toggle Understanding Strip Ratio in Surface MiningIntroduction
1. Introduction to Gossans Definition:Gossans are iron-rich, weathered outcrops formed by the oxidation and chemical weathering of sulfide-bearing mineral deposits. They appear as rusty, reddish-brown to yellow zones on the Earth’s surface and are critical indicators of potential subsurface mineralization. Formation:Gossans develop through the supergene alteration of sulfide ores (e.g., pyrite, chalcopyrite) in the near-surface […] Table of Contents Toggle 1. Introduction to Gossans2.

Porphyry copper deposits are among the most significant sources of copper globally, accounting for over 60% of the world’s copper production . 1. Geological Overview a) Geological Background Porphyry copper deposits are typically associated with magmatic arcs related to subduction zones, where an oceanic plate subducts beneath a continental or another oceanic plate. This tectonic […] Table of Contents Toggle 1. Geological Overviewa) Geological Background
Introduction Ore-bearing hydrothermal fluids are one of the most important agents in the formation of mineral deposits. These fluids, which originate from various geological processes, have the ability to dissolve, transport, and deposit metals in economic concentrations. The study of hydrothermal fluids is crucial for understanding ore genesis and guiding mineral exploration. This article provides […] Table of Contents Toggle Introduction1.

Introduction Alteration in geology refers to mineralogical, textural, and chemical changes in rocks due to interactions with fluids, temperature variations, and pressure changes. This process occurs in diverse geological settings, including hydrothermal systems, weathering environments, and metamorphic terrains. Understanding alteration is essential in mineral exploration, petrology, geotechnical engineering, and environmental studies. This article explores the […] Table of Contents Toggle IntroductionTypes and Processes of Alteration
Introduction The Induced Polarization (IP) method is one of the most effective geophysical techniques used in the exploration of sulfide ore deposits. This method is particularly useful for identifying disseminated sulfide minerals, which are commonly associated with copper (Cu), gold (Au), silver (Ag), zinc (Zn), and lead (Pb) deposits. This article provides a detailed overview […] Table of Contents Toggle Introduction1. Understanding the Induced Polarization (IP) Method
Introduction Gold exploration is a complex process that requires a combination of geological knowledge, geochemistry, and geophysical techniques. One of the most effective methods for locating gold deposits is the identification of pathfinder elements and minerals. Pathfinder elements and minerals are geochemical indicators that suggest the presence of gold nearby, even if the gold itself […] Table of Contents Toggle IntroductionWhat Are Pathfinders for Gold Deposits?
Introduction Structural control is one of the most significant factors influencing the formation and distribution of hydrothermal gold deposits. Structural geology determines the pathways for mineralizing fluids, the locations of ore deposition, and the overall geometry of gold-bearing zones. Understanding these structural controls is essential for exploration geologists seeking new gold deposits and for mining […] Table of Contents Toggle IntroductionStructural Controls in Hydrothermal Gold Deposits
Introduction to Geology Geology, derived from the Greek words geo (Earth) and logos (study), is the scientific discipline dedicated to understanding the Earth’s composition, structure, processes, and history. It seeks to answer fundamental questions: How did mountains form? Why do volcanoes erupt? What clues do rocks hold about ancient life? From the atomic structure of […] Table of Contents Toggle Introduction to GeologyThe Scope of Geology: What Do Geologists Study?
