The gravity anomaly measures at least 3 milliGal amplitude, over approximately 3 square kilometres, with the anomaly centre coincident with a local circular magnetic anomaly, within a broad zone of elevated gold geochemistry.
The gravity has the physical dimension of acceleration and is often expressed in a CGS unit milligal (1 mGa1= [10.sup.-5] m [s.sup.-2]).
A milligal is a convenient unit for describing variations in gravity over the surface of the Earth.
