Two hearths and a pit were discovered at Ballynamuddagh during archaeological monitoring in 2000, carried out ahead of the course's construction. Alongside them, the western edge of a fulacht fia was also uncovered, though only partially excavated.

A fulacht fia is a type of prehistoric cooking site, typically identified by a horseshoe-shaped mound of heat-shattered stone and charcoal built up around a trough that would have been filled with water and heated using fire-cracked rocks. They are found across Ireland in their thousands and date mainly to the Bronze Age, though some examples span a wider period. The Ballynamuddagh finds, recorded under Excavation Licence 00E0398, were fully excavated in the case of the hearths and pit, while the fulacht fia was only partially investigated, its full extent presumably continuing beyond the excavated area. The work was published by Gregory in 2002. What the hearths were used for, and how they relate to the fulacht fia nearby, remains a matter left open by the partial nature of the investigation.
