The Eagle showing area is underlain by rocks of the Upper Triassic Suthini group and limestone of the Lower Permian Stikine Assemblage. Three holes were drilled in the Eagle zone (Bear Pass and QBS areas) and they intersected northwest dipping chert/argillite sediments, conglomerates, heterolithic tectonic breccia and chert breccia units as well as numerous dikes of felsite, diorite and dacite.
Drill hole TR 88-10 at the Bear Pass zone intersected significant tetrahedrite, galena, arsenopyrite and pyrrhotite mineralization throughout the chert breccia and wide zones of low grade precious metals were intersected, including 8.0 meters grading 0.69 gram per tonne gold and 2.0 meters grading 3.1 grams per tonne gold and 18.17 grams per tonne silver (Assessment Report 18555). Sphalerite and chalcopyrite has also been reported.
