These sites, found in their thousands across Ireland, are generally interpreted as Bronze Age cooking places, where stones were heated in fire and then dropped into a water-filled trough to bring it to the boil. They almost always appear near water, and the one at Drummin is no exception, positioned with a stream running approximately forty metres to the west.

The site came to light not through any targeted excavation but during fieldwalking along the planned route of the N52 Nenagh Bypass link road, a survey carried out by Hughes and O'Brien in 1999. This kind of pre-construction archaeological prospection has been responsible for uncovering a considerable number of Irish sites that might otherwise have remained unknown beneath farmland. What the team found at Drummin was a spread of blackened, fire-cracked stone, the characteristic signature of repeated heating and cooling that gives fulachta fia their distinctive burnt and fractured appearance. A small metal fragment was recovered from the top of the spread, though its nature and significance are not elaborated upon. Notably, the site does not stand alone; a second burnt spread of the same type lies roughly ninety metres to the south-west, suggesting that this particular stretch of low-lying ground saw repeated or prolonged use over time.
