The BX occurrence is located on the east side of a small creek valley, approximately 4 kilometres northeast of the Bethlehem Copper (MINFILE 092ISE001) pit and 9 kilometres northwest of Logan Lake.
The area is underlain by quartz diorite (Guichon variety; Highland Valley phase) of the late Triassic-Middle Jurassic Guichon Creek Batholith, which is cut in places by finer dike rocks correlated with the Witches Brook phase of the batholith.
Locally, a long, north-trending, altered shear zone has been exposed by trenching on the original BX claims. The shear zone is at least 762 metres long and 122 metres wide. The altered rock is chlorite-rich and the shear zone is surrounded by partially brecciated, sheared, weathered or decomposed quartz diorite. Iron-rich calcite veinlets run through the area, giving rise to considerable rust staining. Hematite, quartz and epidote veinlets (up to 7 centimetres wide) are also present. In the BX trenches, chalcopyrite and bornite predominantly occur in fine veinlets striking north and dipping approximately 45 degrees west. Associated vein minerals include malachite, generally associated with soft chloritized zones, and azurite with minor chrysocolla, confined to more siliceous areas. Pyrite is generally associated with the chalcopyrite and is more abundant. The veins were followed for a couple of hundred metres and are continuous.
To the east, on the Eden and Ezra claims, scattered outcrops of altered granodiorite hosting disseminated chalcopyrite and malachite are reported.
In 1958, a sample (A2) from trench C yielded 0.8 per cent copper over 3.3 metres, and a sample (A1) from trench H yielded 2.60 per cent copper over 0.9 metre (Assessment Report 246).
In 1969, diamond drilling on the shear zone intersected mineralization ranging from 0.5 to 2.5 per cent copper across widths of 1.2 to 7 metres (Geology, Exploration and Mining in British Columbia 1969).
In 2012, diamond drilling yielded up to 0.375 per cent copper over 1.8 metres and 0.137 per cent copper over 4.5 metres in hole HN-12-02 (Assessment Report 33784).
Prior to 1958, the showing was trenched by B.X. Mining Company. In 1958, the Bob, Star, B.X. and Cow groups of claims were optioned by Noranda Exploration Company Limited and work consisted of a ground electromagnetic survey and geological mapping. Some bulldozer trenching was done on the showing on the B.X. claims and 8 kilometres of road was constructed; the options were dropped at the end of the summer. In 1965, an induced polarization survey (15 kilometres) was completed on the Cow claims on behalf of The Consolidated Mining and Smelting Company of Canada Limited. In 1967, Bethlehem Copper collected soil samples in the area, immediately south, as the Pay claims. In 1969, work done on behalf of Laura Mines Limited on the WJ claims, which covered the BX showing, consisted of 93 kilometres of line cutting, 1567 soil samples, 93 kilometres of ground magnetometer surveying, 43 kilometres of induced polarization surveying, geological mapping, four trenches, totalling 152 metres, and nine diamond drill holes, totalling 853 metres.
During 1964 through 1969, New Indian Mines completed programs of soil sampling and prospecting, an induced polarization survey and an unspecified amount of drilling on the area to the east as the Eden and Ezra claims. In 1968, Vananda Explorations completed a 25.0 line-kilometre induced polarization survey on the Eden area. In 1973, Azure Resources completed a program of geological mapping and a ground magnetic survey on the claims. In 1982, Cominco completed an induced polarization survey on the area immediately to the east as the For claims.
In 2012, Blue River Resources completed a program of soil sampling, a 23.1 line-kilometre induced polarization survey and five diamond drill holes, totalling 1182.5 metres, on the area as the Highland North property. In 2013, the area was prospected as the BX South property and rock samples were collected. In 2015, a photogeological lineament study and a 3.0 line-kilometre ground magnetic survey were completed. In 2016, Guy and Chris Delorme completed a structural analysis and localized magnetometer survey on the Bertha claim group designed to delineate structures related to potentially economic mineral zones.
