The Kitkat 2 showing is located near the Nitinat River, just north of the Raft showing (092F 311) and northwest of the Kitkat showing (092F 282), about 17 kilometres east of Alberni Inlet.

The area is underlain mainly by basalt, pillowed basalt, basaltic tuff and agglomerate of the Devonian Nitinat Formation and lesser pyroclastics the Upper Devonian McLaughlin Ridge Formation (Myra Formation), both of the Paleozoic Sicker Group. The volcanics have been intruded by Early to Middle Jurassic Island Plutonic Suite. The mafic volcanics contain gabbroic sills.

In this area, discontinuous shearing and fracturing tend to parallel large scale regional structures, specifically the fault zone forming the Nitinat River valley. Gossans are associated with the mineralized shears, which occur mainly in coarse-grained, hornblende-rich basalt. Pyrite occurs as a replacement of hornblende. The basalt is typically chloritized, with lesser alteration minerals consisting of pyrite, sericite and epidote. Areas of intense shearing contain quartz veins with pods of massive sulphides (mainly pyrite).

Two zones of massive sulphides, showings A and B, occur in hornblende basalt. Showing A contains massive pyrite and minor pyrrhotite and magnetite, with samples assaying over 1 per cent copper. One hundred metres to the north, Showing B contains patches and disseminations of pyrite in vuggy quartz veins and sheared basaltic rock. A sample assayed 1.7 grams per tonne gold and 0.06 per cent copper and another sample assayed 0.24 per cent molybdenite, 0.1 per cent cobalt and 0.1 per cent zinc (Assessment Report 13945).

The Kitkat showings were first explored by Gunnex Ltd. between 1963 and 1966. This work involved regional silt sampling and prospecting. In 1985 and 1986, JBL Resources completed programs of geological mapping, geochemical sampling, prospecting and VLF-EM and magnetometer surveys. This work identified the five Kit Kat occurrences: Kitkat (MINFILE 092F 282), Kitkat 2 (MINFILE 092F 284), Kitkat 3 (MINFILE 092F 149), Kitkat 4 (MINFILE 092F 218), Kit Kat 5 (MINFILE 092F 461). In 2011, Gold Ridge Explorations Inc. completed a regional program of litho-geochemical sampling, helicopter-borne versatile time domain electromagnetic (VTEM) and aeromagnetic geophysical surveys, totalling 34 square kilometres, on the area as the Columbia Shear property. In 2012 and 2013, Golden Peak Minerals Inc. completed programs of geological mapping, geochemical (soil, rock and silt) sampling and a 24.35 line-kilometre ground magnetometer survey on the area. In 2017, New Point Exploration Corp. completed a program of rock, soil, silt and moss mat sampling on the area as the Columbia Shear property.
