The expression "hit/strike pay dirt" means to suddenly find or discover something valuable or useful, especially after a lot of effort or searching. This phrase is often used in situations where someone has been looking for something for a long time and finally discovers it. It can be used in both literal and figurative ways. For example, a gold miner who finally finds a vein of gold deep in the ground has "hit pay dirt," but someone who has been searching for a job for a long time and finally gets an offer could also be said to have "hit pay dirt."
