A trial excavation was conducted for the purpose of locating the eastern boundary of the Er-Rujum site (Permit No. A-2619*; map ref. NIG 1997/6296; OIG 1497/1296), prior to area development in the Nesher industrial zone. Eleven probe trenches (length 30 m), spaced 10 m apart, were dug along the eastern fringes of the site. Five trenches were aligned north–south and six were east–west. Six of the 11 trenches yielded no archaeological finds. A fieldstone surface was discerned in two of the trenches and potsherds dating to Early Bronze Age I were found in two other. The site had previously been excavated by A. Mazar and P. de Miroschedji (ESI 7–8:79).
