Mantle Minerals (MTL) has restarted gold exploration at the Roberts Hill zone within its Mallina project in Western Australia.
Following a geochemical review of aircore drilling carried out in 2021, the company confirmed it intersected ‘Hemi-style’ mineralisation at Roberts Hill.
The company said it would now complete follow-up exploration activities in the area, including a soil geochemical survey to uncover the best ways to define drilling targets across the tenement.
Mantle will collect more than 750 soil samples from two separate areas on a
100-metre-by-100-metre grid spacing to uncover possible soil anomalies above mineralisation.
It said it would also incorporate geophysics, regional structural geology and detailed studies of previous drilling to help identify targets.
Mantle Minerals Executive Chairman Nick Poll said the surveying could help shape broader exploration efforts in the future.
“If it [the soil geochemical survey] works, then we can scale the method up and explore larger areas,” Mr Poll said.
“This is important because we know that gold deposits in this area can be difficult to find with shallow drilling, so if we’re going to persevere and drill deep, then it better be in the right place.”
Results from the survey are expected during May 2023, with potential drilling to be carried out later in the year.
The Mallina project is located directly north of De Grey Mining’s (DEG) 10.6 million ounce Hemi gold project.
