Acting on a tip off, a raid was carried out during which 2,160 gelatin rods and 3,000 detonators were seized, police said.
Two persons have been arrested and were being interrogated in connection with the seizure.
A jeep was also recovered from the spot and it is suspected that the vehicle was used to transport the explosives, it said.
There have been several instances of recovery of explosives over the last several months in Mirzapur, which is a Naxal affected area.
