The latest results from ongoing drilling at the 300E Zone included 51.93 g/t Au uncut over 11.96m true width.
The 300 Zone is about 300m north of the main 8 Zone which has provided the bulk of Eagle River's production over the past 20 years, with a head grade of about 9g/t.
President and CEO Duncan Middlemiss said the up-plunge drilling at 300E continued to show "wide and rich intercepts" and good continuity vertically, adding that development on the 864m East level was underway with stope production expected at the end of 2017.
"We remain very excited about this new production area with well above average widths, and will continue to focus exploration efforts on this area next year," he said.
The company has produced gold for 30 years and said it was well positioned to achieve its 2017 guidance of 52,000-58,000 ounces.
The Eagle River complex, in Wawa, produced 15,493oz of gold in the September quarter, with 13,313oz coming from the underground Eagle River mine at a head grade of 9.71g/t and the remainder from the Mishi openpit.
Wesdome shares were up almost 14% yesterday to C$2.04, capitalising the company over C$273 million (US$213 million).
