The above intercept also returned 556.5m at 1.38g/t Au-eq and averaged 2.34g/t Au-eq over the last 57m, before the drill reached its maximum limit, Tudor said.

Other highlights included 86.5m at 1.6g/t Au-eq within 786.7m at 0.76g/t Au-eq.

The Copper Belle-Goldstorm Deposit has a measured and indicated resource of 19.4 million ounces Au-eq and an inferred 7.9Moz Au-eq.

"Clearly, much more drilling is required to constrain the deposit which appears to have the greatest potential for continued expansion to the northeast and northwest," VP exploration and project development Ken Konkin said.

"This system has proven to be much larger than we previously expected and, combined with our recent discoveries at Perfect Storm, Eureka and Calm Before the Storm, gives this project unparalleled economic potential as one of the largest gold projects in the world."

The Eric Sprott-backed company confirmed the Calm Before the Storm discovery last week.

It had raised C$15 million earlier this month for more exploration.

Tudor owns 60% of Treaty Creek. American Creek Resources (TSXV: AMK) and Teuton Resources (TSXV: TUO) each hold 20% and are carried through to a production decision.

Tudor shares (TSXV: TUD) rose almost 2% yesterday to close at C$2.05, at the lower end of a one-year range, valuing it at $381 million (US$299 million).

American Creek gained 5% to 21c, while Teuton lost 1% to $1.95, capitalising the pair at $83 million (US$65 million) and $109 million (US$86 million) respectively.
