The occurrence is located in the Dewar Creek and White Creek area, approximately 30 kilometres northwest of Kimberley.
Sedimentary rocks of the Lower and Middle Aldridge Formation underlie the occurrence area. The sediments are Proterozoic in age and consist of quartzwackes, quartz arenites, and siltstones. The sediments in the area have been folded into a northwesterly striking anticline. Diorite sills and dikes of the Proterozoic Moyie Intrusions intrude the strata.
The Hilo 3 or Main showing occurs about 35 metres southwest of a diorite contact in thinly interbedded quartzites and siltites. Minor amounts of fine-grained galena and pyrrhotite are disseminated along 6 mililimetre thick planes which parallel bedding and occasionally transect it. This mineralization is limited to a 7.5 metre wide band of outcrop. Fine-grained chloritic material is associated with the sulphides. Most of the occurrence is hosted in quartzite with lesser amounts in the siltites.
In 1957 to 1958, Consolidated Mining and Smelting Company Ltd. conducted prospecting, mapping, trail building and a magnetometer electromagnetic survey on the property containing the occurrence. This is when the occurrences on the property were discovered.
In 1971, Texas Gulf Sulfur conducted sampling and geological mapping over the main showing on the property.
In 1976, Cominco Ltd. completed a single drill test resulting in 1.1 metres grading 0.35 percent lead, and 0.30 percent zinc (Price, B. (2012-10-15): Technical Report, Vulcan Property). The report does not specify which occurrence the drilling was conducted on.
In 1982 to 1984, Cominco conducted a geochemical sampling program, an UTEM, and HLEM survey over the property containing the occurrence.
In 1985, Cominco completed mapping, contour and grid soil geochemical programs, UTEM and HLEM surveys, and a five-drill hole program.
In 1991 to 1992, Ascot Resources conducted two drilling programs focusing on the extent of the Lower Aldridge Formation zone in the area.
In 2006, Eagle Plains Resources conducted an electromagnetic geophysical survey on the property containing the occurrence. An anomaly was identified that traces the contact between the Lower and Middle Aldridge units between the Hilo 5 and Hilo 10 mineral occurrences.
In 2011, Eagle Plains Resources Ltd. with Navy Resources Corp. conducted a large gravity gradiometry survey on the area including the occurrence.
In 2019, SJ Geophysics completed a 2.8 line-kilometre hybrid Volterra Magnetotelluric (MT)/Volterra Induced 3D Polarization (3DIP) geophysics survey focused the southern part of the Vulcan property.
In 2020, Eagle Plains completed a program of prospecting, geochemical (rock, soil and silt) sampling and two diamond drill holes, totalling 975.2 metres, with borehole electromagnetic surveys on the area as the Vulcan property.
