The framework due by the end of June will demarcate a total area of 1,000 square kilometers (386 square miles) where companies can search for rare earths, and introduce auctions for the right to explore for the deposits, according to Balvinder Kumar, the top bureaucrat in the nation’s Ministry of Mines.

“At the moment it isn’t clear about who can explore which areas,” Kumar said in an interview Tuesday in New Delhi. “There will be clarity now.”

The South Asian nation has one of the world’s bigger reserves of rare earths, a group of obscure minerals produced mostly by mines in China. Prime Minister Narendra Modi’s government is trying to cut the complex red tape and land acquisition hurdles that have prevented the nation from fully exploiting not just rare earths, but also rich seams of resources such as coal, bauxite and gold.
