Exploration

Geomysore applied for a Mining Lease over an area of 5.97 sq km in the year 2006. The Government of Andhra Pradesh had advised Geomysore to submit an approved mining plan for considering the grant of Mining Lease. Accordingly, Geomysore submitted a Mining plan to Indian Bureau of Mines in 2008, which was approved on 04th August 2008. Geomysore also received the Environmental Clearance from Ministry of Environment and Forest in 2010 which is valid till 2043. Geomysore also received CFO and CFE for Jonnagiri Gold Project from APPCB.

Since the grant of Mining Lease, Geomysore has carried out extensive advanced exploration which includes trenching, soil sampling, IP survey, magnetic survey and drilling. About 33,000m of close spaced drilling has been done from which Geomysore could establish 5.7mt at 1.45g/t with a gold content of 8.28t in East block, 1.1mt at 2.98g/t with a gold content 3.28t in the west block and 0.05mt at 1.77g/t with a gold content 0.1t in south block. Geomysore has completed NI43-101 compliant Feasibility Study on onnagiri Gold Project, which is the first such study to be done on any gold project in India. As a part of this, Geomysore has carried out all the technical studies eg., drilling, resource estimation, ore benefication studies, Geotechnical studies, pit optimization and scheduling, tailing dam design and other infrastructure items.

Pit optimization in East Block shows that the ore can be economically mineable by open pit method up to the depth of 180m and the quantity of ore can be mined is about 4mt with a gold content of 6.5t at 0.6g/t cut-off.
