Significant surface radioactive anomalies, with values up to 0.177% eU3O8 (n = 9), located during 1992 along the non-conformity contact of basement granitoid with the Srisailam Formation, around Chitrial village, Nalgonda District, Andhra Pradesh, led to the establishment of a sizeable uranium deposit by recent exploration. Thus, intensive subsurface exploration resulted in delineating the persistency of the mineralization
