The NORTH LOBE occurrence is located approximately 44 kilometres north-northeast of Williams Lake, and approximately 60 kilometres southeast of Quesnel, British Columbia. In the southeast part of the Ben (now Beaver) property, the North Lobe occurrence is situated between the Mount Polley Mine and the Gibraltar Mine. The Beeaver property lies on the Fraser Plateau, a flat and gently rolling area mostly covered by glacial drift. The property covers a northwest trending height of land between the Beedy Creek and Beaver Creek Valleys, two prominent topographic lineaments considered to mark significant faults (Assessment Report 35173).
Situated within the Cache Creek Terrane, the North Lobe occurrence is underlain by rock units of the Permian to Triassic-aged Cache Creek Complex. Noted rock units include marine sedimentary and volcanic rocks including phyllite, siliceous phyllite, ribbon and massive chert, argillite, mudstone, sandstone, limestone, tuff, mafic volcanic rocks, and serpentinite. The area is bounded to the east and to the west by rocks of the Quesnel Terrane. The structural geology of the Ben property is not well understood or documented. The fabric of the underlying sedimentary and volcanic rocks trends north-northwest (Assessment Report 35173).
Although not formally mapped, drilling across the Ben (now Beaver) property intersected several zones containing shallow-dipping, variably serpentinized dunites, with lesser peridotites and gabbros. The serpentinite is mostly composed of antigorite and lizardite. Accessory magnetite (up to 10 per cent) and chlorite are dispersed within serpentine-rich pseudomorphs and within vein-like domains. The ultramafic rocks occur within interbedded marine sedimentary rocks of the Cache Creek Complex (mudstone, greywacke, sandstone, conglomerate), and volcanic rocks (tuff, dacite, basalt). Alteration styles include serpentinization and silicification. Nickel and cobalt mineralization are hosted in variably magnetic serpentinized ultramafic rocks, mostly contained within the nickel-sulphides heazlewoodite and pentlandite, with possible millerite (Assessment Report 35173).
Targeting magnetic anomalies, 2014 drilling encountered variably serpentinized dunite, shale, mudstone, and silicified volcanic rocks. Nickel mineralization in drill holes BN14-22 and BN14-23 appears to be associated with a 100 metre wide serpentinite body at the top of an ultramafic sequence dipping approximately 45 degrees to the southwest. Results from drilling include 57.7 metres grading 0.21 per cent total nickel (0.17 per cent sulphide nickel), and 0.011 per cent cobalt (in BN14-22 from 63.1 to 120.8 metres down hole depth) (Assessment Report 35173).
In 2021, a diamond drill hole, collared a few hundred metres north of the North Lobe prospect, returned the following values: DDH B21-04 averaged 0.19 per cent nickel, 0.01 per cent cobalt, 0.29 per cent chromium and 23.6 per cent magnesium over an 18.5 metre interval.
WORK HISTORY
Very limited work was recorded on the North Lobe occurrence until Westhaven Ventures optioned the property from claim owner B.H. Kahlert in 2012. Rock geochemical samples were taken, and one induced polarization line (2 kilometres) was completed (approximately 1 kilometre south) in 2012 (Assessment Report 33544).
In 2014, Westhaven Ventures completed a property wide airborne magnetic survey, consisting of 851 line kilometres, with flight lines oriented east-west and spaced at 200 metre intervals. The North Lobe occurrence was defined by the airborne magnetic survey, and occurs as a 200 to 1000 metre wide, strong, elongated linear anomaly, trending 4.5 kilometres in a northwest direction and extends off the property to the southeast. Follow up work at North Lobe included prospecting and soil sampling (Grid D – with the Ring Zone), identifying multiple parallel, northwest-striking zones of anomalous nickel values. Throughout 2014, 3 drill holes (412.03 metres) were completed over two campaigns.
In 2021, Inomin Mines Inc. conducted eight line-kilometres of VLF-EM and 291 line-kilometres of ground magnetometer over their Beaver property, including the North Lobe prospect. Follow-up drilling focusing on magnetic anomalies was done in 2021 and 2023 in an area extending from approximately 3 kilometres north of the North Lobe occurrence to 3 kilometres south. Drilling intersected uniform concentrations of sulphide nickel, cobalt and magnesium mineralization in shallow, south to southwest-dipping serpentinites in most areas (Assessment Reports 40133, 41401). Two further airborne (helicopter and drone) magnetic surveys were completed over Inomin's Beaver-Lynx project in 2024 and 2025 (Press Release inominmines.com Feb. 6, 2025).
