The region of the Bor occurrence is underlain by two phases of the Hogem batholith that intrude sedimentary rocks of the Upper Triassic Inzana Lake Formation, Takla Group. One phase consists of Late Triassic to Early Jurassic gabbroic to dioritic rocks. The second phase consists of Early Jurassic quartz monzonitic to monzogranitic intrusive rocks.

A new copper occurrence was discovered in 1999 by prospectors Lorne and Chris Warren. A road side rock pit 10 metres by 75 metres exposes a sheeted breccia zone in monzonite-diorite-syenite intrusives. The open fractures on the margins of the breccia fragments have been filled with chalcopyrite, magnetite and iron pyrite masses up to half a metre in diameter. Very little alteration minerals occur with the mineralization. No significant chalcopyrite occurs in the top two metres in the pit exposure. This may explain why no copper mineralization was found during surface prospecting of the Bor pit area. Poor copper soil results were also reported over this copper showing.

One grab sample yielded 1.3 per cent and 0.09 gram per tonne gold (Assessment Report 26451, page 23).

Earlier work in the vicinity is described in the JP 1 (Tbor) occurrence description (MINFILE 093N new) to the west and the Falcon (093N 068) to the southwest. It appears that none of the historical claims covered the Bor gound, except for that of the vast claim holdings worked by Geoinformatics Exploration in 2007.

In 2010, a subsequent AeroTEM survey by Redton Resources identified 65 EM anomalies on its large Redton property; a total of 646 line-kilometres were flown and included coverage over the Bor area (Assessment Report 31933). In 2012, Kiska Metals (previously Rimfire Minerals Corporation) conducted a field program, consisting of the collection of soil samples and prospecting (Assessment Report 34050). A total of 568 soil samples were collected in 2012. Grid E was located north of the Falcon prospect, consisting of 4 lines spaced at 250 metres in an east-west direction. A total of 83 soil samples were collected from this grid most of it over the Bor and to its immediate north. For rock samples were also collected, apparently from the locality of the original 1999 sampling, however the only gold assays were reported and these were all low. All the samples were reported to have been taken in diorite to gabbro-diorite rocks with chalcopyrite, pyrite plus or minus magnetite.

See Falcon (093N 068) for related geological details and information on the Redton property which the Bor was also part of in the 2000s and 2010s.
