The TL-11 occurrence area is underlain by granodiorite to quartz diorite of the Early Jurassic Topley Plutonic Suite. Contact with rocks of the Lower Jurassic Telkwa Formation (Hazelton Group) occurs to the immediate south where rocks consist of basalt and andesite with lesser amounts of rhyolite, rhyodacite and dacite.
In 2006, Telkwa Gold Corporation located mineralization on their Limonite Creek property consisting of tenures 535231 and 535233). Copper mineralization (malachite) was detected in sheared quartz diorite outcrop and assayed 1.2 per cent copper (Sample TL-11, Assessment Report 29213). A quartz vein adjacent to the mineralized fracture did not contain visible mineralization other than red iron staining and specular hematite. The sample site was reported as not being well-mineralized.
The mineralized fracture trends 055 and dips 90 degrees. It is crosscut by another fracture striking at 170 degrees and dipping 84 degrees west. Just to the east of this sample site and north of the cirque lake, is a prominent topographic break in the slope that trends east-northeast and trends toward the outcrop of sample TL-11. Several quartz veins mineralized with specular hematite were observed along this break. This 055-degree trend is parallel or sub parallel to the east-northeast trend of the alteration zones previously mapped in the 1992-94 grid to the south. This data in conjunction with the trend of the alteration zones mapped to the south indicates a regional structural pattern that appears to be associated with mineralization at Limonite Creek.
