Yes, traditional asset-based royalties, such as those tied to natural resource extraction (mining and oil) or specific patents and pharmaceutical drugs, do eventually run out. In the mining sector, a mineral royalty terminates once the underlying mineral reserves are fully depleted or if mining operations become permanently uneconomic and shut down. Similarly, intellectual property and pharmaceutical royalties expire when patents reach the end of their legal protection terms. To mitigate this finite lifespan, successful royalty companies continuously acquire new properties or fund early-stage exploration pipelines to replace depleting assets.
