Excavation by P M G Jones for SCAU, Runnymede Borough Council and English Heritage to provide information for management of the monument. Mesolithic worked flints including cores were found. The postulated defences were sectioned and the site was confirmed as a univallate hillfort; a full detailed survey was carried out by RCHM(E). In a small trench in the interior 53 prehistoric features were found, mostly of early to middle Iron Age date, with post-holes indicating three or more building phases.
Report on detailed fieldwalking of 96ha (237 acres) by S P Dyer and Judie English for the SyAS Surrey Historic Landscapes Project Team. A thin scatter of worked flint was found throughout the area; mostly Neolithic with some Mesolithic and some BA. Sherds of Neolithic and BA pottery were also found. Aerial photographic evidence shows that the higher ground around Bocketts Farm is covered by a Celtic field system, perhaps to be associated with the known occupation site at Hawks Hill, but no Iron Age pottery has yet been found.
A watching brief on topsoil stripping during construction of the golf course was carried out by Rob Poulton of SCAU for BMP Building Ltd. No archaeological features and only a few pieces of worked flint of Mesolithic or Neolithic date were observed.
Observation of trenches dug to prevent occupation of the site and of foundation work by S P Dyer for SCAU and Homebase Ltd produced five struck flints of Mesolithic or early Neolithic type; no features were located but the flints are thought to indicate a nearby site (279)
Excavation by M Reynier of Nottingham University, for the British Museum, of an area adjacent to the 1977/8 excavation by Dr R M Jacobi (site 103, Kettlebury). A large collection of flints was recovered, including two hollow-based points which are characteristic of Early Mesolithic Horsham assemblages. Another characteristic of Horsham assemblages, the chamfered flake or blade, was not recovered, but two characteristic chamfer spalls were.
Excavation by D W Williams for SyAS in advance of mineral extraction revealed two concentrations of activity. One was a concentration of pits, three of which contained Late Neolithic grooved ware and, palaeo-environmental assessment revealed, hazelnut shells; one of these pits also contained over 30 flint scrapers. Other pits were packed with charcoal and cremated bone, and one contained a Bronze Age spiral ring. The surrounding areas produced a variety of flints from Late Mesolithic through to Middle Bronze Age date, and sherds of decorated Peterborough type bowls from the Neolithic.
Evaluation by J Robertson of SCAU, for TAG McLaren Holdings Ltd, of the site for the new TAG McLaren HQ, revealed a general spread of features of prehistoric (both Mesolithic/Early Neolithic and Bronze Age), Roman and medieval date. The majority of the features were gulleys and ditches. No focus of activity was identified. It seems likely that the settlement(s) lay outside the evaluated area, possibly near Mizen’s Farm itself.

Evaluation by J Robertson of SCAU, for Malcolm McD Hooker & Co, in advance of residential development adjacent to a known findspot of Palaeolithic & Mesolithic flints. A small quantity of struck flint was recovered, probably of Mesolithic date, but the pieces were dispersed in the top & sub soil. (314)
Evaluation by J Saunders of TVAS, for Bryant Country Homes Southern Ltd, was carried out in advance of residential redevelopment. The site of the Hydestile Hospital, where Roman or medieval pottery was recovered in 1943, was found to be extensively disturbed; no features or finds of archaeological interest were noted. The site of the King George V was less disturbed, but the only find recovered was a flint flake, possibly Mesolithic. (319)
Evaluation by J Robertson of SCAU, for BFI Ltd, of two areas permitted for mineral extraction, produced little of archaeological interest except for an area centred at SU 861 473. Here no features were revealed, but numerous finds of both prehistoric and Roman date were recovered. Analysis of the soils from which these finds were recovered indicates that they are essentially hillwash. This suggests occupation nearby, on higher ground, in both the prehistoric and Roman periods. Unfortunately, the area of higher ground adjacent has previously been quarried.
