The Black Pilot property is located on the east side of the Rocher Deboule Range, 10 kilometres south of New Hazelton.

Middle Jurassic to Lower Cretaceous Bowser Lake Group clastic sedimentary rocks are overlain by andesitic flows of the Upper Cretaceous Brian Boru Formation (Kasalka Group). The Rocher Deboule granodiorite stock, of the Late Cretaceous Bulkley Plutonic Suite, is located 400 metres west of the showings.

The Katherine showing is located on the south side of Porphyry Creek at 1190 metres elevation, and consists of a 2-metre wide vein containing barite and minor sphalerite cutting andesite. On the north side of Porphyry Creek, at 1550 metres elevation, pyritic beds of greywacke and argillite have been prospected by several open cuts and an inclined shaft. On the divide between Mudflat Creek and Porphyry Creek, a pyrite vein at the contact between a lamprophyre dike and argillites has been explored in an 8-metre long adit.

Work History

In 1918, the Leverett Brothers drove a 10.3-metre tunnel on the Black Pilot (Leroi group. A 3 metre wide vein was intersected.

In 1927, D. MacDonald, work continued on the Black Pilot occurrence.

In 1930, D. MacDonald, conducted work on the Black Pilot which included a 12 metre tunnel on the Summit claim on a 0.9 metre wide vein. An Open-cut exposed a 4.9 metre wide mineralization on the True Blue claim. And a 12 metre inclined shaft, a short tunnel and a 4.6 metre tunnel on the Black Pilot open-cuts.

In 1931 D. MacDonald conducted Assessment work on the Summit, True Blue and Black Pilot mineral claims.

In 2010, Dunham Gold Corp completed a 495 kilometre airborne geophysical survey on its Porphyry Creek property which covered numerous showings including the Black Pilot (Assessment Report 31728).

Refer to Sultana (093M 061) for further details of the Porphyry Creek property work history, of which the Black Pilot was part of.
