The Willow showing is located approximately 4 kilometres southwest of Sustut Peak (Geology, Exploration and Mining in British Columbia, 1973).

The regional geology is similar to the Sustut deposit (094D 063). The stratigraphy at the Willow comprises augite porphyry breccias overlain by a sequence of thinly-bedded aphanitic basalts, fossiliferous shales, chert and carbonate beds, and a thick volcaniclastic unit. The strata is locally offset by faults which are subparallel to a strong set of cross-joints, which strike 25 degrees and dip steeply to the southeast. The occurrence is hosted in the Upper Triassic Savage Mountain Formation (Takla Group) and is thought to be hosted in a lower stratigraphic horizon than the Sustut deposit.

The mineralized horizon is a thin discontinuous tuffaceous argillite bed just below the volcaniclastic unit. Mineralization consists of both chalcopyrite and chalcocite, which form discrete grains less than 1 millimetre in diameter. The copper sulphides are disseminated in varying concentrations and can constitute as much as 30 per cent by weight, in some samples (Geology, Exploration, and Mining in British Columbia, 1973).

In 1997, Cross Lake Minerals collected a grab sample from the Willow showing that consisted of disseminated bornite in shale which assayed 4.94 per cent copper and 35.4 grams per tonne silver (Assessment Report 25267).

WORK HISTORY

The first documented geological mapping in the vicinity of the Willow property was in 1948 by Lord, who documented several mineralized showings in the area during a regional geological mapping survey (GSC Memoir 251).

Wesfrob Mines Ltd., owner of the Willow prospect in 1973 was completing a major drill program on the Sustut copper deposit located to the northwest. Cross Lake Minerals reported that Westfrob drilled 945 metres in two deep holes, due to the steep topography, in order to intersect the Willow mineralization. The results of these holes are unknown.

During 1974 and 1975, N.B. Church completed regional mapping and property descriptions, including the Willow prospect, for the Department of Energy, Mines and Petroleum Resources.

In 1997, Cross Lake Minerals completed a single line of soil/talus sampling on the side of the creek draining south down the center of their Willow 1 claim where bedrock was not exposed. The samples were collected from the talus fines at the higher elevations and soil from the B and C-horizons in the lower timbered areas. The sample spacing was 50 metres and a total of 32 samples were collected. It was explained that due to extremely steep terrain only “grabs” were collected. The Willow showing area was described as a large gossan at the base of a steep cliff.
