The Eagle showing occurs in the Refuge Bay area, near the northwest corner of Porcher Island near the Surf Point Mine (103J 017), 36.9 kilometres south-southwest (209°) of Prince Rupert, B.C..
Mineralization occurs at the contact between a Cretaceous to Tertiary quartz diorite stock and Paleozoic-Mesozoic greenstones from an unnamed formation. Auriferous pyrite occurs in a north- east striking quartz vein, within a shear zone up to 0.6 metres wide. The vein occurs largely in the greenstone and is cut-off by a basic dyke. A representative sample of the mineralization assayed 120 grams per tonne gold and 31 grams per tonne silver (Minister of Mines Annual Report 1932, page 50).
Cathedral Gold's new Edye Zone appears to be coincidently located with the old Eagle (Dawson) workings, both occurring about 400 metres west-northwest of the Surf Point Mine (AT Zone, 103J 017). Drill hole 11 apparently intersected the old Eagle (Dawson) zone, cutting a quartz vein in diorite adjacent a basalt dyke (Assessment Report 16735).
The Edye Zone is reported to have similar mineralization to that of the AT Zone (Surf Point Mine). At least seven drill holes have been completed on the Edge Zone with best intersection grading 8.91 grams per tonne gold over 4.3 metres (George Cross Newsletter #92, May 12, 1988).
In 2015, Imperial Metals Corp. conducted an exploration program to locate old showings on their Porcher Island property. The program included 9 rock samples from showings, 32 soil samples and 12 stream sediment samples. A high grade rock sample #780402 assayed 13g/t Au gold and was a grab sample of quartz with 10% pyrite collected at the historic Dawson underground workings dump. (Eagle showing). The stream sediment sampling proved successful in delineating the Edye Shear, a known gold bearing area, as a gold target (Assessment Report 35801).
