The Telegraph Range occurrence is located in the northern portion of the Telegraph Range, east of Holman Lake.

The region is underlain to the west by the Mississippian to Triassic Cache Creek terrane and to the east by the Quesnel terrane and the Omineca Belt. The boundary between the Quesnel and Cache Creek terranes is probably the southern extension of the Pinchi fault system. Ultramafic rocks of ophiolitic affinity, now variably deformed and metamorphosed, were tectonically emplaced within the Cache Creek Group.

The Telegraph Range occurrence consists of chrysotile asbestos within serpentinized peridotite.

Work History

In 2005, Louis E. Doyle completed a program of prospecting and geochemical (rock, soil and stream sediment) sampling on the area as the Legra 1-17 claims of the Telegraph property. A rock sample (TELRO533) assayed greater than 1.00 per cent copper (Assessment Report 28244). No sample descriptions were provided.

In 2016, Barkerville Gold Mines Ltd. completed a 548.7 line-kilometre airborne magnetic and electromagnetic survey on the area as the Zippermouth property. In 2019, Barkerville Gold Mines Ltd. completed a program of rock and silt sampling on the property.
