 The prospect is located in 2, side-by-side gravel pits found along a lumber road, approximately 500 m north of Christie Lake. Christie Lake is approximately 30 km northeast of Halifax and is immediately west of Big Indian Lake.

 NSMOD #D13-026
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, andalusite
