Great Boulder Resources Ltd (ASX:GBR) has completed an aerial electromagnetic (EM) survey at its Mt Carlton Project in Western Australia.
The survey generated two priority large targets known as the Eastern Zone and Western Zone, both anomalies being over three kilometres in length.
The 3.5-kilometre-long Eastern Zone anomaly is coincident with ultramafic rocks and a zone of elevated nickel.
The 3.7-kilometre-long Western Zone anomaly is coincident with a mapped banded iron unit suggesting potential gold mineralisation.
Great Boulder intends to conduct further field reconnaissance of the anomalies, followed by soil and rock chip sampling over both areas to further refine the targets before proceeding with surface geophysical surveys.
Management thinks targets could host nickel and gold
Great Boulder’s managing director Andrew Paterson said: “Finding two anomalies, both more than 3km long and coincident with known geological features is very encouraging.
"The Eastern Zone in particular is an exciting target given it sits over elevated nickel within mapped ultramafics and on the edge of a big gravity response.
“We think this has the potential to be a big disseminated nickel target.
“The Western Zone anomaly is also a strong target. The thickening of the greenstone belt in that area with juxtaposed regional faults on either side is characteristic of a dilational structural setting, which makes it highly prospective for gold.”
Mr Carlton is 60 kilometres south of the company’s Yamarna Project and was acquired from Gold Road Resources (ASX: GOR) in August 2019.
