TG Metals (ASX:TG6) said recent historical drilling at the Van Uden gold project in Western Australia is expected to add to the existing mineral resource estimate after resurveying of the drill collars by TG Metals with an accuracy sufficient for resource modelling, according to a Monday filing on the Australian bourse.

The drilling was conducted by the previous operator of the project, Montague Resources Australia, and it confirmed the continuity of the gold mineralization system down dip and along strike.

Mineralisation interpretation has been completed by TG Metals' in-house geology team at the project as part of the mineral resource estimate update, which is expected to be completed during May.

The firm also plans to conduct drill testing of existing mine stockpiles.

Its shares rose 2% on market close on Monday.
