The Woof showing is located 1.5 kilometres northwest of the Finn zone (MINFILE 094E 171), approximately 5.25 kilometres north-northeast of the Kadah Lake and 3.75 kilometres south of Oxide Peak. It lies within the Omineca-Cassiar mountains at the southern end of the Toodoggone gold camp.

The Woof showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation, Hazelton Group.

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The Woof showing is underlain by a thick succession of Lower Jurassic volcanics assigned to the McClair and Metsantan members of the Toodoggone Formation, separated by a low angle thrust (?) fault. The Metsantan Member consists of latite flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The McClair Member consists of heterogeneous, lapilli to block tuff, andesitic flows and numerous cogenetic dikes and subvolcanic plugs; minor mudstone and conglomerate (Bulletin 86). Both members are dominated by flows and flow breccias around the Woof showing (Assessment Report 18015). This sequence is cut by a series of steeply dipping diabasic and rhyolitic dikes.

Alteration on the Woof showing is structurally controlled and ranges from weak propylitic to intense silicic, argillic and sericitic. Propylitic alteration is the most widespread and important alteration type of the prospect, either hosting mineralized veins or forming haloes around more intensely altered and mineralized systems. Propylitic alteration consists of replacement of plagioclase phenocrysts by epidote or hematite and mafic phenocrysts by chlorite, epidote, actinolite, talc and disseminated calcite (Assessment Report 18015).

The Woof zone itself consists of two distinct brecciated vein systems and outcrops, approximately 150 metres apart and are characterized by breccia zones and related mineralization adjacent to northwest and north-northeast trending cross faults, at or near their intersections with a low angle thrust (?) fault. The southern zone consists of a 1 to 2-metre wide breccia zone of hematitic and argillic altered, and brecciated andesite cemented by milky white quartz with visible gold. The north zone consists of a 1-metre wide calcite, sphalerite, acanthite (?) vein. Both vein systems strike northwest and have sub-vertical dips.

The zone(s) consists of andesites with local mineralized veins, shear/gouge zones and brecciated zones. A 1-metre wide, northwest-trending (vertical) zone of brecciation on top of the ridge consists of argillically altered and hematized andesite fragments supported in a leached, vuggy quartz matrix. The shear zones trend steeply east-west (90 to 105 degrees) and range in width from 0.2 to 1.0 metre. These zones contain angular, blue-grey, very siliceous fragments in a tan to orange-grey clay gouge. The quartz veins are subparallel to the shear zones and range in width from several centimetres to 1 metre. These veins are milky white to blue-grey (similar to the fragments included in the shear zones). Visible sulphides in these veins and shears are 1 to 15 per cent disseminated pyrite, with trace chalcopyrite and sphalerite. A small zone of siliceous andesite with a stockwork of 10 per cent quartz stringers (in subcrop) contains trace of chalcopyrite and malachite. One vein, 1 metre in width and trending steeply northwest, is mineralized with minor sphalerite.

In 1981, two samples (1543 and 18456) of siliceous hematitic breccia near the contact of green and maroon volcanics were collected from the area of the Woof occurrence and yielded 0.99 and 32.57 grams per tonne gold with 21.26 and 30.86 grams per tonne silver, respectively (Assessment Report 9372). Later that year, two samples (61455 and 61457) from the Woof zone area yielded 17.0 and 15.0 grams per tonne silver with 15.05 and 14.02 grams per tonne gold, respectively, and 1.16 grams per tonne gold with greater than 50 grams per tonne silver from samples (61458-61467) of quartz hematite float located approximately 850 west-southwest of the Woof zone (Assessment Report 9833).

In 1983, a grab sample (26070) from the southern zone returned 79.2 grams per tonne gold and 30.5 grams per tonne silver (Assessment Report 11843).

In 1988, grab samples from the southern and northern zones returned 34.0 and 5.3 grams per tonne gold with 23.1 and 3650 grams per tonne silver, respectively (Assessment Report 18015).

In 1994, two grab samples (145615 and 145616) from the Woof zone yielded values of 26.58 and 96.36 grams per tonne gold with 25.0 and 69.4 grams per tonne silver, respectively, whereas a grab sample (145622) of argillic altered feldspar porphyry with disseminated pyrite over a 10-metre wide zone, located approximately 500 metres to the north, yielded 0.72 gram per tonne gold. (Assessment Report 23663).

In 1995, three chip samples (957, 976 and 987) from the Woof zone yielded 18.0, 18.5 and 8.2 grams per tonne gold with 28.8, 26.2 and 334.0 grams per tonne silver over 1.0 metre each, respectively, whereas a grab sample (958) of mineralized calcite veining assayed 63.3 grams per tonne gold, 34.3 grams per tonne silver, 0.154 per cent copper, 0.400 per cent lead and 1.43 per cent zinc (Assessment Report 24284). Drilling, also performed at this time, yielded no significant intercepts.

In 2015, samples from the Woof zone yielded up to 35.4 grams per tonne gold and 44.8 grams per tonne silver (Assessment Report 33556).

In 2018, a select grab sample (100364) of epithermal quartz veinlets in weakly silica-chlorite–altered andesite(?) assayed 3.45 grams per tonne gold and 9.5 grams per tonne silver (Assessment Report 38203).

Work History

Recent work History in the Woof area included rock and soil sampling in 2012 by Tower Resources and aeromagnetic surveying by Duran Ventures in 2008. The 2008 airborne magnetic survey in the area referred to as Grid 1 extends from the area of the Creek zone (and generally associated Schmidt and Woof high grade vein targets) northward into a cluster of magnetic responses suggesting a high level intrusive system Duran's 2008 program reported gossans of interest in this sector.
