President and CEO Duncan Middlemiss said the resource update would lead into a preliminary economic assessment expected in early 2020 "and next steps will be determined at that juncture".
The company celebrated 30 years on the Toronto Stock Exchange last month and reported stronger-than-expected June quarter production results.
Wesdome shares have been on an upward trajectory over the past 18 months, from about C$2 at the start of 2018 to touch $7.02 intraday yesterday, the highest point since March 2003, according to Bloomberg.
They closed down 2.47% to $6.72, on a day Toronto's gold equities collectively closed down 4%, capitalising Wesdome at $917 million (US$694 million).
