The Burr Prospect occurs in the southeast corner of district Lot 292, on the west bank of the Similkameen River and 5.5 kilometres southwest of Princeton.

This coal deposit is situated in the south-central part of the Princeton Basin, a northerly trending fault-bounded trough filled by Eocene volcanic rocks of mainly intermediate composition, comprising the Lower Volcanic Formation, and an overlying Eocene sedimentary sequence of sandstone, shale, waterlain rhyolite tephra (tuff) and coal, up to 2000 metres thick, comprising the Allenby Formation.

The deposit may correlate with the Pleasant Valley-Jackson coal zone, one of four significant coal-bearing zones in a 530-metre section in the Allenby Formation (Princeton Group) (Geological Survey of Canada Paper 52-12, page 22).

An adit exposes a seam of coal, 2.0 metres thick, with seven partings of shale, clay and bentonite up to 6 centimetres thick, and one band of dirty coal, 48 centimetres thick. The seam contains 86 centimetres of clean coal (Geological Survey of Canada Paper 52-12, Figure 2, prospect 2). It strikes 170 degrees and dips about 20 degrees west. Underground workings have followed the seam downdip for about 30 metres.

The deposit was explored by E. Burr in 1945.
