These two maps (1998-9 and 1998-10), at 1:100 000 scale, display the geology and mineral occurrences of the western margin of the Kechika Trough between Gataga River and the 60th parallel.


The Kechika Trough is a Lower Paleozoic feature which connects northward to the Selwyn Basin. Together, these features represent an important metallotect within the northern Canadian Cordillera, hosting several large, world class sedex massive sulphide deposits (Cirque, Akie, Driftpile Creek, Howards Pass, Tom, Jason, Anvil).


In addition to the detailed geology of the northern Kechika Trough, these maps contain the locations and brief descriptions of numerous new mineral occurrences of sedex origin.  The number and distribution of these occurrences, together with similar showings to the south, reinforces the importance of the Kechika Trough as a sedex province and indicates its potential to host other large deposits.
