The HOOK showing, is located approximately 1.7 kilometres northeast of Lea Lake and 11.7 kilometres north-northeast of the village of Horsefly. It is within the Cowtrail property as are the Cowtrail (093A 266), BM (093A 116) and Middle Lake (093A 362) showings. Access to the area is provided by a paved road from 150 Mile House to Horsefly, and then several bush roads from ranches occupying the Horsefly River valley.

The oldest rocks on the property belong to the Upper Triassic-Lower Jurassic Nicola Group and consist of a submarine sequence of augite basalt flows and wackes that are overlain by massive felsic tuff breccias (probably volcanic equivalents of crosscutting alkalic intrusions) which in turn are overlain by a dark grey siltstone. The youngest unit are maroon analcite-bearing basalt flows and breccias of probable subaqueous origin. At least four intrusive centres are known to exist on the Cowtrail property including the the “Hooker Lake syenodiorite”, the “Middle Lake Alkalic Entity”, the carbonate altered “BM” felsic unit and the Lea Lake (Cowtrail) zone. Two of the known intrusive centres, the Middle Lake Entity and the Hooker Lake syenodiorite, may be coeval with the younger volcanic lithologies and are probably subvolcanic in origin. They occur as virtual windows in a till-covered terrain and may coalesce under this cover.

The Hook showing occurs in one of these alkalic plutons, the “Hooker Lake syenodiorite”, where its composition is fine to medium-grained monzonite and syenodiorite with weak propylitic alteration. The first recorded work over the current Cowtrail property area was by Hudson’s Bay Oil and Gas in 1974 who conducted surface work including geological mapping, soil sampling and ground geophysics (IP and magnetometer) surveys on their Hook claims. This was followed up with three 91.4 metre deep percussion drill holes over a weak to moderately strong IP anomaly. Theses holes, 74 H-1, 2 and 3, are located in the northeastern part of the current Cowtrail property, 0.5 to 1 kilometre south of Hooker Lake. The holes encountered monzonite and monzonite porphyry with 5 per cent sulphides, mainly pyrite, but only minor copper sulphides. Copper results were low (Assessment Reports 5087, 5088, 5089).

From 1987 through 1991, R.M. Durfeld conducted geological mapping, soil, rock and stream sediment sampling over the Cowtrail property, mostly to the west of the Hook showing anomaly (Assessment Report 17647). Eastfield Resources staked part of the Cowtrail property area in 1991 and optioned it to Cogema Canada who later that year contracted an airborne geophysical survey to Aerodat which was followed up with a soil geochemical program (Assessment Report 22086). The airborne survey data was not recorded for assessment.

The area was re-staked by Wildrose Resources Ltd. in 2004 as the Cowtrail property, to cover airborne geophysical anomalies derived from surveys completed in 1967 and 2004 and also to cover the original BM (MINFILE 093A 116) and Hook showings. Subsequent airborne magnetometer surveying, completed by the BC Ministry of Energy, Mines and Petroleum Resources in 2003 and released in 2004 (Open File 2004-9), shows a well-defined total field magnetic feature extending to the northwest of the Middle Lake Stock. The magnetic feature is 2.1 kilometres long and varies from 450 to 650 metres in width.

In 2005, Wildrose Resources Ltd. (now Cariboo Rose Resources Ltd.) granted an option to Dajin Resources Corp. to earn a 65 per cent interest in Cowtrail. From 2005 to 2011 Dajin Resources Corp. conducted rock and soil geochemical surveys and ground IP and magnetometer surveys resulting in target areas for 2007 and 2011 drill programs.

The 2011 drilling comprised 3 holes on the Lea Lake zone, 2 holes at the northwest end of the Middle Lake Stock, 1 hole on the Hook showing and 1 hole approximately 500 metres west of the Hook showing. Neither CT-2011-14, collared near 1974 drill hole 74H-2 nor drill hole CT-2011-15, collared 500 metres west of the Hook showing, contained values of either gold or copper that were significantly above background levels.

In 2021, Cariboo Rose Resources conducted grid soil sampling southwest of Lea Lake, west of Jim Lowry Lake and in the northeast between the Hook showing and Murdock Lake (Assessment Report 39712).
