Great Boulder Resources Ltd (ASX: GBR)

Great Boulder is a mineral exploration company looking for gold and base metals in Western Australia. With over 1,000km2 of tenements spread across its key projects at Kalgoorlie, Meekatharra and Yamarna the Company is leveraged for exploration success.

Having made two large-scale copper-nickel sulphide discoveries at Yamarna within two years of listing, GBR has a track record of exploration success backed by a strong technical team. Early-stage exploration success on the gold projects in recent months have now set the Company up for an exciting year ahead.


The Whiteheads Project 45km north of Kalgoorlie is an emerging discovery. With large, coherent gold anomalies at surface and regional-scale mineral system potential the Whiteheads gold story is only just beginning. The project is also prospective for nickel sulphides and VHMS base metals systems.

Side Well

Despite its location in the heart of a 7Moz historic gold field at Meekatharra, Side Well remains largely unexplored. High-grade intersections in historic drilling at Mulga Bill demonstrate the project’s potential. Drilling is continuing to define this 3.7km-long prospect, with early-stage work aimed at generating new targets in other areas of the project.

Winchester is located 40km north of Mt Venn. With Cu-Ni sulphides identified at the Winchester Prospect, the project has potential for higher nickel tenor with regional synergies with Yamarna.
