Bidgood Kirkland Mine

"The Bidgood is a small gold mine about 5 miles east of the main Kirkland Lake camp. Since the beginning of production in 1934, gold having a value of $5,000,000 has been produced from the property. Practically all of this production has come from seven veins in a diorite stock that intrudes the Timiskaming sediments and lavas of the area. The veins consist of quartz, pyrite, and molybdenite with minor amounts of chalcopyrite, calcite, and tellurides, and occupy northeast striking and northwest dipping thrust fault fractures. They have no apparent direct structural association with the faults of the main Kirkland Lake camp or the Larder Lake 'break' to the south; however, the veins closely resemble the former in their mineralogical composition and in their close association with syenite intrusives.ROCK TYPES AND THEIR STRUCTURAL CHARACTERISTICSThe dominant and, from an economic standpoint, most important rocks in the ore area consist of two separate families of Algoman intrusivesa diorite and a later syenite group."
