Consider the following statements: 1. In Rajasthan, the mines of manganese ores are found at Banswara and Udaipur. 2. In Andhra Pradesh, manganese ores are found at Visakhapatnam. Which of the statements given above is/ are correct ?

Both statements are correct regarding the distribution of manganese in India. In Rajasthan, manganese ore deposits are primarily concentrated in the Banswara and Udaipur districts [c3][t1]. Banswara is particularly significant, contributing over 90% of the state's manganese resources [t1]. In Andhra Pradesh, manganese ores are found in the Visakhapatnam and Srikakulam districts, which are the leading producers in the state [c1][c2]. Other districts in Andhra Pradesh with manganese occurrences include Vizianagaram, Guntur, and Cuddapah [c1][c2]. The ores in Andhra Pradesh are often associated with the 'Kodurite' rock type [t5]. Nationally, while Odisha and Madhya Pradesh are the leading producers, Rajasthan and Andhra Pradesh remain important contributors to India's mineral inventory, with Andhra Pradesh accounting for approximately 6% to 11% of the country's manganese production [c1][t9].
