I want to know the answer to the following question:
What kind of mines are found in Khetri and Jhunjhunu ?
All the background I'm provided with is that "It has rich salt deposits at Sambhar, copper mines at Khetri, Jhunjhunu, and zinc mines at Dariba, Zawar mines and Rampura Aghucha (opencast) near Bhilwara.". Is that enough to answer the question?
Answer: yes
