The Cliff (Turn) occurrence is located about 72 kilometres east of Dease Lake.

The prospect is hosted in an Alaskan-type ultramafic intrusive complex. This zoned complex consists of a dunite core and surrounding peripheral peridotites, pyroxene-rich peridotite, and olivine pyroxenite with maximum dimensions of 3 by 8.2 kilometres. It was intruded in the Early Jurassic (and earlier?) into Upper Paleozoic(?) and/or Triassic(?) metavolcanic and metasedimentary rocks of the Quesnel Terrane. It is in faulted contact on the east and north with slate and phyllite of the Ordovician to Mississippian Road River Group (Ancestral North America). The magmatic evolution of the composite intrusion extended over at least four million years in the Early Jurassic (ca. 189-185 Ma). This span of intrusive activity is a minimum as the oldest Stage 1 component of the Turnagain complex has yet to be dated (Nixon et al. (2018-2019)).

The mineralized area occurs near the eastern end of the complex. Net textured pyrrhotite, pentlandite and chalcopyrite occur in a band of poikilitic serpentinized peridotite in contact with an underlying pegmatitic pyroxenite, all hosted within a large unit of magnetite clinopyroxenite. Net-textured chalcopyrite occurs at the contact between the peridotite and the pegmatite and is also found as disseminations within shears. Mineralization occurs over an area of at least 75 by 100 metres (Assessment Report 15994, Figure 4). The showing has been extensively sheared and is fault bounded to the north.

Falconbridge Nickel Mines explored this showing and several others as the Turn property from 1966 to 1973. Four packsack holes were drilled in the showing area in 1970 but results were never published (Assessment Report 3735 - Claims and Grid Location figure M1). The Cliff showing was resampled for platinum and palladium by Equinox Resources in 1986. The highest value for platinum was 0.30 gram per tonne and for palladium, 1.45 gram per tonne (Assessment Report 15994).

WORK HISTORY

In 2007, holes 07-236 to 07-240 were drilled in the prospective Cliff Area by Hard Nickel Creek Corp. According to Hard Nickel Creek holes 07-237 to 07-240 intersected very encouraging nickel, platinum and palladium grades, expanding on known mineralization encountered in (pre-NI43-101) drill holes completed in 1997, while hole 07-236 intersected no significant intervals.

Hole 07-237 was drilled to test the central part of the Cliff Area near a mineralized wehrlite outcrop and to determine the depth to the ultramafic contact. Hole 07-237 intersected olivine clinopyroxenite and clinopyroxenite with visual sulphide estimates of up to 5 per cent to a depth of 37.80 metres. From this depth to 276.15 metres, the hole intersected variably serpentinized dunite and wehrlite with rare olivine clinopyroxenite and clinopyroxenite with visual sulphide estimates ranging 0.5 to 7 per cent. At 276.15 metres a faulted, graphitic phyllite was intersected until end of hole at 305.10 metres. Analyses yielded total nickel values of 0.25 per cent and platinum plus palladium values of 0.34 gram per tonne from 112 to 124 metres and total nickel values of 0.21 per cent and platinum plus palladium values of 629 grams per tonne from 204 to 216 metres (Assessment Report 29748).

In 2008, Hard Creek drilled holes 08-249 to 08-253 into the Cliff Zone to find new mineralization and to test for possible along strike and down dip extensions of mineralization intersected in holes 07-237 to 07-239 (Assessment Report 30367). Drilling results were mixed. Hole 08-250 intersected nearly barren dunite, despite its proximity, 100 metres northwest to the 2007 holes, and indicated a possible between holes 07-237 to 07-239 and 08-250. The lack of mineralization in hole 08-253, to the south of the 2007 holes, is thought to reflect the gently dipping nature of previously encountered mineralization and geology. Hole 08-249 intersected mineralization fairly similar to the 2007 holes and it is located approximately 100 metres to the southeast. The presence of moderate-grade PGE mineralization with sulphide nickel and copper occurs in more than one area of the Cliff Zone.
