* Simple Subject: "mines"
* Predicate: "are found in South Africa"
Let's explain why:
* Simple Subject: The simple subject is the main noun or pronoun that the sentence is about. In this case, it's the "mines."
* Predicate: The predicate tells us something about the subject. It includes the verb ("are found") and any other words that complete the thought about the subject (in this case, "in South Africa").
