The Spanish East gold anomaly is located between Spanish and Flourmill creek, approximately 7 kilometres north of Mahood Lake.

The area is cut by the Eureka thrust fault, separating Mesozoic rocks of the Quesnel terrane to the west from Paleozoic and older rocks of Omineca terrane to the east. Both assemblages have been intruded by Cretaceous stocks, plugs, and dike swarms of granite to granodiorite composition.

Locally, quartz-sericite-chlorite-pyrite altered schists of the Eagle Bay Assemblage host numerous quartz-pyrite veins. These have been exposed in a former logging road aggregate pit.

The area was first prospected in 1999 by D.W. Ridley using newly constructed logging roads and as a part of Prospector’s Assistance Grant (99/00 P62). Sampling of mineralized material returned up to 300 parts per billion gold, 3137 parts per million arsenic and 25 parts per million antimony (Assessment Report 28981). In 2006, the claims were again prospected by D.W. Ridley.
