The MJ (Bacon Lake) occurrence is located approximately 850 metres east of Bacon Lake at an elevation of approximately 560 metres.

The area is underlain by Karmutsen Formation volcanics that are overlain by Quatsino Formation limestone, both of the Upper Triassic Vancouver Group. These in turn are overlain by volcanics of the Lower Jurassic Bonanza Group. Plutonic rocks of the Early to Middle Jurassic Island Plutonic Suite intrude these rocks and vary in composition from gabbro to quartz monzonite but are mainly granodiorite and quartz diorite.

Locally, andesite interbedded with limestone and calcareous sediments, is intruded by granodiorite. The volcanics have been silicified and in part altered to skarn along the contact, with disseminated and vein magnetite occurring in several places. In two locations the limestone has been completely turned to skarn and contains semi-massive to patchy magnetite with associated pyrite and lesser chalcopyrite and malachite.

In 1989, a sample (B-89-5B) of granodiorite assayed 0.255 per cent copper, 5.252 per cent zinc and 0.023 gram per tonne gold, as well as containing hematite, pyrrhotite and actinolite (Assessment Report 18946).

In 1987, R. Tessolini prospected the area as the Bacon claims. In 1989 and 1991, M. Sawiuk completed programs of geological mapping, rock sampling and ground magnetometer surveys on the area. In 1997, IMA Resources Corporation completed a program of geochemical sampling and geological mapping on the area as the Bacon 1-4 claims. During 2009 through 2013, Western GateWay Minerals explored the area as part of the Bacon Lake property.
