The correct answer is: Only 1 and 3.
The first statement is true because hilly terrain makes mining difficult. The second statement is false because there is a problem of unauthorized mining in the state. The third statement is true because the Himachal Pradesh Minor Mineral Policy is revised.
The hilly terrain of Himachal Pradesh makes mining difficult because it is difficult to access and transport the minerals. This makes mining more expensive and less profitable. As a result, there is less incentive for companies to mine in Himachal Pradesh.
The problem of unauthorized mining in Himachal Pradesh is due to the lack of law enforcement in the state. The government does not have the resources to monitor all of the mining activity that takes place in the state. As a result, some people mine minerals without a license or without following the proper safety procedures. This can lead to environmental damage and accidents.
The Himachal Pradesh Minor Mineral Policy was revised in 2016. The revision was intended to address the problem of unauthorized mining. The new policy requires all miners to obtain a license and to follow the proper safety procedures. The government also increased the penalties for unauthorized mining.
The revision of the Himachal Pradesh Minor Mineral Policy is a positive step towards addressing the problem of unauthorized mining in the state. However, it is important to note that the government will need to enforce the new policy in order to be effective.
