How long do quarries usually last?

The lifespan of a quarry can vary significantly depending on factors such as the type of material being extracted, the size of the quarry, and market demand. Generally, quarries can operate for anywhere from a few years to several decades. Some quarries may exhaust their resources in as little as five years, while others, particularly those extracting high-demand materials, can last over 50 years. Ultimately, the duration is influenced by both the availability of resources and economic viability.
