Every mine develops at a different pace. The discovery of a major mineral deposits may create feverish excitement, but an actual mine may remain undeveloped for decades, waiting for a favourable alignment of investors, infrastructure developments, or market conditions.
Some mines develop rather suddenly, however, leading to the “rush” conditions that have been romanticized in popular culture. Mineral rushes may lead to riches for some, but they also can create impossibly difficult conditions for miners and their families, including poor housing, hunger, diseases, and high accident rates in the mines.
