Since the 1900s, gold mining has evolved significantly due to advancements in technology and changes in regulations. Early mining relied heavily on manual labor and basic tools, whereas modern operations utilize sophisticated machinery, automation, and data analytics for exploration and extraction. Environmental considerations have also become more prominent, leading to stricter regulations and a focus on sustainable practices. Additionally, the globalization of the gold market has transformed the industry, with increased international investment and competition.
