Further Info:

 The type and style of mineralization is similar to that at the Millet Brook Uranium Deposit, Hants County, Nova Scotia.
Finely disseminated U-bearing phosphates (torbernite and autunite), chalcopyrite and pyrite are associated with an extensively hematized northeast-trending, shear zone. The uraniferous zone extends for approximately 100 m along the shear.
Rock types exposed in the gravel pit encompass all phases of the Big Indian Polyphase Intrusive Suite. The wall rocks exhibit intense hydrothermal alteration, including high-alumina hydrothermal alteration as reflected by the presence of andalusite, cordierite, sillimanite, spinel, garnet, muscovite, biotite and tourmaline.

Other Minerals:
 autunite, chalcopyrite, pyrite, torbernite, sillmanite
