The COWTRAIL (DDH01) showing is located approximately 400 metres east of the north end of Lea Lake and 10.5 kilometres north-northeast of the community of Horsefly. It is within the Cowtrail property as are the BM (093A 112), Hook (093A 116) and Middle Lake (093A 360) showings.

The oldest rocks on the Cowtrail 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 units are maroon-coloured analcite-bearing basalt flows and breccias of probable subaqueous origin. Four intrusive centres are known to exist on the Cowtrail property including the "Lea Lake" intrusive, ‘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.

Drillhole 07-DDH-01 defines the Cowtrail occurrence within the Lea Lake intrusive body. Observed mineralization is in a potassium-altered micro-diorite in contact with a pyritic metavolcanic unit, and a dark-green to grey aphanitic basalt, with moderate to intense alteration to chlorite, epidote, calcite and pyrite as well as silicic and potassic alteration. Pyrite occurs in blebs and stringers and is disseminated throughout the basalt. The highlight of drillhole 07-DDH-01 was a 18.3 metre interval assaying 1.16 grams per tonne gold and 0.043 per cent copper (Assessment Report 30539).

Highlights of the 2011 drill program include drillhole CT-2011-12, collared 55 metres south of 07-DDH-01, which assayed 0.11 gram per tonne gold and 0.17 per cent copper over 40 metres, from the top of bedrock at 32.2 metres to 72.2 metres downhole (Assessment Report 33196).

Drill hole CT23-16 was the highlight of the 2023 drill program on the Lea Lake zone returning 0.15 per cent copper over 105 metres, including 15.0 metres of 0.23 per cent copper and 0.1 gram per tonne gold. In 2025, drill hole CT25-23 returned assays of 0.2 per cent copper and 0.1 gram per tonne gold over 70 metres starting at 86 metres downhole, including a 20 metre intercept of 0.26 per cent copper and 0.14 gram per tonne gold; hole CT25-24 assayed 0.11 copper and 0.08 gram per tonne gold over 108 metres starting at 29 metres downhole with deeper intercept of 0.134 gold over 99 metres (PR REL Cariboo Rose Resources, Nov. 27, 2025).

WORK HISTORY

The Cowtrail property area has been explored since the 1970’s for porphyry copper-gold deposits with most of the work conducted on the northern half of the property. In 1974 the BM Showing; a zone of strongly carbonate-argillic altered intrusive, was discovered by Domes Mines. Also in that year, Hudson’s Bay Oil and Gas conducted surface work including geological mapping, soil sampling and ground geophysics (IP and magnetometer) surveys on their Hook claims. Subsequently, 3 percussion holes totalling 274.2 metres were drilled on the property, discovering the Hooker Lake syenodiorite and encountering sulphide mineralization (Assessment Reports 5087, 5088 and 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.

In 1996, Eastfield Resources teamed up with Imperial Metals Corp. targeting results from the 1991 Aerodat survey. An IP survey was completed in 1996 east of Jim Lowry Lake, which was followed up with diamond drilling later that year and again in 1997. The three northernmost holes, 97-B-20, 21 and 22, over the strongest part of the anomaly, encountered a pyritic and strongly potassic altered monzonite intrusion that was named the “Middle Lake Stock” (see Middle Lake Minfile 093A 360) (Assessment Report 25491).

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 (MINFILE 093A 116) 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, the Cowtrail property was consolidated with the addition of the Rat and Jim claims belonging to Amarc Resources Ltd. 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. Wildrose Resources Ltd. (now Cariboo Rose Resources Ltd.) subsequently 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.

In 2007, Dajin Resources Corp. completed 7 HQ diamond drill holes totalling 1420 metres on seven of the ten identified IP anomalies (Assessment Report 30539) and in 2011 conducted a 7-hole NQ diamond drill program totalling 2740.5 metres on the Cowtrail property (Assessment Report 33196). The highlight of the 2007 drill program was the discovery of the Lea Lake zone (Cowtrail (DDH01) prospect. In addition two drill holes investigated the BM showing anomaly. 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.

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) and in 2022, a soil survey was conducted over the BM area in the northwest region of the Cowtrail property (Assessment Report 40594).

In 2023, 5 NQ diamond drill holes totalling 690.68 metres were drilled by optionee BRS Resources Ltd. on the Cowtrail property. Two holes were drilled on the Lea Lake zone, 1 in the BM zone and 2 south of the BM known intrusive area (Assessment Report 41403). In 2025, BRS Resources conducted a 4 hole diamond drill program totalling 1138 metres, targeting the Lea Lake zone, a southeast-trending mineralized corridor associated with historic induced polarization anomalies and coincident magnetic features extending beyond the original 2007 discovery intercept.
