Jammu, May 12 -- The Union ministry of mines will put on sale 12 limestone blocks in the Union territory of Jammu & Kashmir on Tuesday. These blocks are located across the districts of Anantnag, Rajouri, and Poonch, and include both newly identified blocks as well as those being re-auctioned under second attempt. This will be the second tranche of limestone blocks auction of in the Union Territory. Building upon the successful initiation of mineral block auctions in the UT, this marks another significant step towards unlocking the region's mineral potential and strengthening its contribution towards the vision of Viksit Bharat and Aatmanirbhar Bharat, stated an official spokesperson here. The blocks are broadly categorised under G3 and G4 stages of exploration, indicating promising geological potential with substantial industrial-grade limestone deposits. The G4 stage is reconnaissance and the G3 stage is prospecting. G4 involves broad-based surveys like regional geological mapping and remote sensing to identify areas with mineral potential, while G3 uses closer-spaced surveys to narrow down specific target locations within those areas. The launch event will be held at Srinagar and will be attended by Piyush Goyal, secretary, ministry of mines. Ashwani Kumar, additional chief secretary, Jammu & Kashmir government, along with senior officials will also be present....
