A characteristic Indus subconical core from which parallel sided blades have been removed before it was discarded.
Two bullet cores from which very narrow bladelets have been removed, and which were then discarded. The blades were made by specialists.
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.
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.
Soil samples were taken for thin section analysis in various areas of the hills to try to understand the climactic variations that took place in the area before, during and after the rise of Harappan culture.
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
