Highlights
- Mineral Resource Growth: Total mineral resources grew by 0.3 million ounces (6%) to 4.81 million ounces (Moz).
- Attributable Ore Reserve Boost: Ore reserves increased by 5%, now standing at 43 million tonnes (Mt) at 1.39 grams per tonne (g/t) for 1.92 Moz.
- Gruyere JV Contribution: The Gruyere joint venture with Gold Fields added 1.1 Moz (18%) to its mineral resource, now totaling 157 Mt at 1.42 g/t for 7.14 Moz.
Gold Road Resources Ltd (ASX:GOR) has announced a significant increase in its mineral resources and ore reserves across its Western Australian projects, marking a step forward in the company’s exploration and operational efforts.
Gruyere Joint Venture Adds Significant Resources
The Gruyere joint venture (JV) played a pivotal role in Gold Road’s resource growth, with its mineral resource increasing by 1.1 Moz (18%) to 7.14 Moz at 1.42 g/t.
- The Gruyere open pit mineral resource alone expanded by 0.83 Moz, now standing at 137 Mt at 1.37 g/t for 6.05 Moz. This was made possible through:
- A 90-meter deeper pit shell, enabled by enhancements in the geology model.
- New drilling data and updated economic assumptions, which made deeper resources economically viable.
The Golden Highway mineral resource, also part of the JV, grew by 0.30 Moz, reaching 19 Mt at 1.57 g/t for 0.96 Moz. This increase was driven by:
- A larger pit shell at the Attila deposit, achieved through extensional drilling and improved economic parameters.
Implications for Future Development
The resource and reserve upgrades underscore the potential for extended mine life and increased production capacity at Gold Road’s Western Australian assets. The enhanced pit designs, coupled with updated economic assumptions, demonstrate the JV’s ability to adapt and optimize operations as new data becomes available.
