The southern boundary of the Cowtrail property, which covers both the BM showing and Hook showing (093A 112), is located approximately 4 kilometres north of the village of Horsefly and 65 kilometres northeast of Williams Lake. 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 showings are between Hooker Lake to the north, and Lea Lake to the south.
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 three intrusive centres are known to exist on the claims including the “Middle Lake Alkalic Entity”, the “Hooker Lake syenodiorite” and the carbonate altered “BM” felsic unit. 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.
At the original BM showing, minor chalcopyrite occurs within basalt and it is not known whether this mineralization is related to the Hooker Lake intrusion. In 1997, reconnaissance drilling undertaken by Eastfield Resources Ltd. (then in a project partnership with Imperial Metals Corporation) identified the “Middle Lake Intrusive Entity” in the area that is now on the Cowtrail 1 claim south of Hooker Lake. The “Middle Lake Entity”, where drilled, included potassic altered syenodiorite (predominantly monzonite porphyry), crowded feldspar porphyry and (quartz)-microdiorite. This intrusion, which was discovered by following up reconnaissance “IP” completed in 1996 is blind and is overlain by wet, clay rich, glaciofluvial till. Holes 97-20, 21 and 22 were drilled on ± 200 metre intervals over a 400 metre extent in the target. These holes intersected a well altered alkalic intrusion over much of their full lengths. The alteration is dominantly potassic and includes abundant secondary potassium feldspar and biotite. While no economic grades of mineralization were encountered, the holes were highly anomalous. The first 59.6 metres of hole 97-B-20 averaged 402 ppm copper and 32 ppb gold with the highest 3-metre sample being 1280 ppm (0.12 per cent) copper and 82 ppb gold. The location of this hole is about 780 metres east of the originally documented BM showing (Assessment Report 27825). The first 57 metres of hole 97-B-21 averaged 355 ppm copper and 13 ppb gold with the highest 3-metre sample being 835 ppm copper and 46 ppb gold. The bottom of hole 97-B-21 (last 18.1 metres) is noteworthy in its high molybdenum content that averages 55 ppm molybdenum with 3 metre samples to 103 ppm.
The Eastfield/Imperial Metals and the competitor claims subsequently lapsed and the area was re-staked by Wildrose Resources Ltd.in 2004 as the Cowtrail property, consisting of the Cowtrail, Rat and Jim claims to cover airborne geophysical anomalies derived from surveys completed in 1967 and 2004, and also to cover the original BM showing and Hook showing (093A 112). Subsequent airborne magnetometer surveying completed by the BC Ministry of Energy, Mines and Petroleum Resources in 2003 and released in 2004, shows a well defined total field magnetic feature extending to the northwest of holes 1997-B-20, 21 and 22. The magnetic feature is 2.1 kilometres long and varies from 450 to 650 metres in width. The access road developed by Eastfield into this area in 1997 followed a cattle trail used by local ranchers and is the origin of the current name of the project. Recent logging that occurred in this area after 1997 upgraded the road, and consequently access into this area is now excellent. The release of Open File 2004-9 by the BC Ministry of Energy and Mines caused considerable staking to occur. Amarc Resources Ltd. was one of the first groups to complete staking and acquired the Rat and the Jim claim groups to cover portions of the airborne magnetic target not covered by the Cowtrail claims. In 2004, Amarc completed an extensive program of induced polarization surveying on the Rat and the Jim claims. A single diamond-drill hole followed up this work in November 2004. This drillhole is 1000 metres north of the originally documented location of the Hook showing (093A 112). The hole intersected a continuous sequence of pyroxene rich volcanic flow belonging to the Nicola Group. The hole contained abundant pyrite, averaging 5 to 6 per cent throughout the hole, but did not return any significant copper or gold values. A single sample was anomalous in molybdenum content and returned a 45 ppm value (Assessment Report 27825).
In April 2005, the Cowtrail, Rat and Jim claims were consolidated into a single property by combining the Cowtrail claims staked by Wildrose Resources Ltd. in January 2004 with the Rat and Jim claims staked by Amarc Resources Ltd. in March and April 2004 (Wildrose was subsequently reorganized into Wildrose Resources Ltd. and Cariboo Rose Resources Ltd. in 2006).
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.
In 2006, Dajin Resources Corp. established approximately 20 kilometres of cut grid line and completed induced polarization and magnetometer surveys on this grid.
In 2007, Dajin Resources Corp. completed a drill program on seven of the ten identified IP anomalies from 2006.
In 2011, Dajin Resources Corp. conducted a seven-hole drill program on the Cowtrail property.
