Gorilla Gold Mines (ASX:GG8) found high-grade gold mineralization during diamond drilling at its Mulwarrie project in Western Australia, according to a Thursday Australian bourse filing.

The results include 8.2 meters at 23.5 grams per tonne grade of gold from 217.6 meters.

The company plans to give a resource update at Mulwarrie in the third quarter and aims to discover significant new mineralisation at the project.

The maiden drilling program will draw to a close in three to four weeks, after which a resource will be re-estimated while further drilling is planned, the filing added.
