Capsule Geology

The Kangaroo showing is situated to the east of Kangaroo Creek, approximately 11.5 kilometres northwest of Likely.

Regionally, the area is underlain by the late Proterozoic to mid-Paleozoic Barkerville and late Triassic to early Jurassic Quesnel terranes. Regional deformation is the result of intense, complex, partly isoclinal folding. The boundary between the two terranes is marked by the Eureka thrust fault. The Barkerville terrane hosts folded sill-like masses of gneissic meta-diorite.

Locally, the Kangaroo showing is hosted in sedimentary and volcanic rocks of the Upper Triassic to lower Jurassic Nicola Group and associated intrusions. An intrusive stock has been mapped out to be approximately 1.0 by 1.8 kilometres at the surface. Skarn and vein-type chalcopyrite and gold mineralization occur preferentially in calcareous basalts, and calcareous and silicified siltstones and veinlets in the dioritic porphyry.

The dominant lithology is fine-grained siltstone. The siltstone varies in colour from light- to dark-grey with fine bedding and occasional fine sandstone interbeds. Siltstones are primarily siliceous. Locally, intense fractures are weakly welded by chlorite. Siltstones are usually rusty with reddish and yellow-brown gossan. Andesitic volcaniclastics distinguished by coarser texture and a light greenish-grey colour caused by high chlorite content are often interbedded with the siltstone. In the northeast, siltstone outcrops have bedding striking northwest-southeast and dipping steeply to the southwest. To the north, bedding strikes northwest-southeast and dips eastward. Veining is predominantly calcite, with minor quartz. Pyrite and pyrrhotite occur as disseminations in all rocks types and in blebs and irregular, narrow sulphide veins in siltstones, basalts and intrusives. Blebby pyrrhotite and pyrite occur mostly at the vein selvages, as well as in narrow sulphide veins and irregularly occurring disseminations in siltstones and basalts. In general, sulphides are more abundant near intrusive contacts and are more abundant in intruded rocks than intrusive rocks. In siltstones, some fine sandy layers appear to be preferentially mineralized with small-scale stratabound sulphides. Drilling intersected dark hornfelsic rocks containing massive pyrrhotite with chalcopyrite and pyrite occurring near apparent intrusive contacts. Magnetism is associated with pyrrhotite.

Pervasive calcite is very common in basalts and also occurs in siltstones and volcaniclastics. Occasionally diorite contains fine calcite veinlets. Intruded rocks contain pervasive sericite, with intense sericite in gougy zones. Chlorite alteration is common and is usually concentrated in chloritic fractures in siltstone. Trace amounts of epidote are present, but distribution is patchy. Localized pervasive secondary silica alteration does occur and can be confused with primary silica in sandstones. In intrusive and intruded rocks, calcite veins are more predominate than quartz veins.

In 2002, Barker Minerals Ltd. collected 24 till samples from an area immediately to the north of the Kangaroo occurrence as part of their Frank Creek-Ace exploration project.

In 2003, Barker Minerals carried out a small exploration program in the Kangaroo Creek area to confirm the geological setting and compare the results with previous observations. That year, 5500 metres of induced polarization (IP) and magnetic geophysical surveying was conducted.

From 2006 to 2007, work consisted of geological mapping, geophysical surveying, diamond drilling and reconnaissance geochemical soil sampling. Nine diamond drill holes totalling, 2008 metres, were completed. The drillholes tested targets from a 2003 geophysical survey and intersected gold mineralization associated with chalcopyrite and multiple pathfinder elements in hornfelsed and altered rocks displaying silicification, sericite and epidote. In total, 915 core samples, 57 rock samples, 46 soil samples and 21 stream sediment samples were collected. An 8.0-kilometre Titan 24 survey and a 32.0-kilometre pole-dipole induced polarization (IP) survey were completed. Geological mapping, completed over an approximately 2.5 square kilometre area covering the drill locations, outlined an intrusive stock or sill estimated to be approximately 1.0 by 1.8 kilometres in size.

In 2016, Barker Minerals Ltd. collected 141 rock samples from outcrop and float. Some samples contained anomalous values for gold in quartz. High gold values were often accompanied by high zinc or copper values. One float sample, sample 437, assayed 12.61 grams per tonne gold, 0.010 per cent copper and 0.009 per cent lead (Assessment Report 36449). The highest gold value obtained from a sample collected from outcrop was sample 491, which assayed 12.81 grams per tonne gold, 0.025 per cent copper and 0.011 per cent zinc (Assessment Report 36449).
