The Telegraph Gold Mine is one pit out of seven pits which are otherwise collectively known as the Lancefield Mine. Historic and modern production at Lancefield was from the southern most pit, west of the Leonora-Laverton Road. The remaining pits form a south-west to north-east line starting 1 kilometre east of the original pit, centred on the Laverton-Warburton Road and Erlistoun Station Roads intersection. The pits were developed by Western Mining Corporation in the late 1980's.

Unlike the other pits, Telegraph produced non refractory ore based on the West Lode structure. The pit has a long vertical ramp forming a pillar around an old shaft and some shallow workings. Laverton's water supply comes from a water bore just north of the shaft.

The map gives an approximate position, based on buildings at the site, which it is assumed relate to the water extraction. Pictures seen and descriptions indicate Telegraph is the pit just north of the buildings but this needs on the ground confirmation.

The deposit is hosted in sheared and flattened pillow basalts. Gold was deposited in the first stage of an east-west contraction in a series of west directed thrusts, dipping moderately east. The strain transformed the ovoid pillow structures into cigar shaped lenses, and ultramafic to mafic schist.
