He said this in a response to a question on a report which alleged a "cover-up" on child deaths in mica mines in 4 states including Jharkhand.
"The mica mines are illegal due to which some deaths have happened. We are in the process of issuing tenders in a couple of months so that mica is sold through e-auction to alleviate such malpractices," Das said at a press conference here.
Referring to the issue, Barnwal said: "We will take care of that. The state government is very serious about it".
Das was here for a roadshow to invite investors to the Global Investor Summit being hosted by the state in February next year.
"There are opportunities in every sector in Jharkhand. We want investors to come to the state to explore these opportunities. I have come to invite investors to the Jharkhand Global Investor Summit to be held in February," Das said, adding that Jharkhand could play a decisive role in Make in India campaign..
