Some of the narrow bladelets discarded by Harappan flint-knappers are only 2-3 millimeters wide. Bladelets were later retouched into insturments in the Indus Valley cities. They were often shaped into microdrills for piercing stone and shell beads.
Flint related objects and activities related to the ancient Indus Civilization.
Four Harappan workshops were excavated, including site 480 from which more than 35,000 artefacts were collected. Most of them were debitage flakes, but also included narrow blades, bladelets and accurately made bullet cores.
Excavation of site 862 revealed that the pit had been used by Harappan miners down to a depth of 1.30 meters where the flint vein was encountered.
From this pit, a radiocarbon reading of a small charcoal fragment indicated that the mine was exploited

The excavation of one of these quarry pits was carried out in February 1995. The excavation took place over a small 2 by 3 meter area facing the Indus Valley.
One of the main minig areas from an altitide of 80 metres. The quarry pits are lighter, semi-circular spots which show areas where sand blown from the neighbouring Thar Desert has been trapped in the quarry depressions.
The cores are of a type typical for Harappan culture, both conical and elongated. The blades have been struck off with the pressure technique. This involves pressing the surface of a flint or flake with a soft-pointed instrument.
