Striking it rich is often termed as hitting what?

The term "paydirt" specifically refers to a layer of soil or rock that yields a profitable amount of valuable minerals or metals, particularly in mining contexts. It symbolizes success and abundance, especially when someone finds something of great value, which aligns well with the concept of "striking it rich." The phrase has been adopted in broader contexts to signify discovering something worthwhile or profitable in any endeavor.

While other options like "jackpot" also suggest wealth and sudden fortune, "paydirt" is more closely associated with the act of unearthing valuable resources directly, which ties back to the mining and prospecting origins of the phrase.
