* Estimates 6.2 mln tons of gold at Phoenix Gold Project

* Shares rise to touch new 52-week high

Nov 29 (Reuters) - Rubicon Minerals Corp gave an initial inferred gold resource estimate of 6.2 million tons at its Phoenix Gold Project in Red Lake, Ontario, sending its shares up to a new 52-week high.

Shares of the Vancouver-based company were up 30 percent at C$5.94 on Monday on the Toronto Stock Exchange. They touched a high of C$6.18 earlier in the session.

"Importantly, the gold grade of 20.1 grams per ton gold is high compared to most major gold deposits around the world and is consistent with the overall Red Lake camp average grade, which is Red Lake's key advantage," Chief Executive David Adamson said in a statement.

The company also said underground development on the project has already cross-cut mineralized zones at the 305 meter level, and delineation drilling is underway. (Reporting by Isheeta Sanghi in Bangalore; Editing by Jarshad Kakkrakandy)
