Aldoro Resources Ltd (ASX:ARN) is preparing for a sampling program over high-interest lithium-rubidium pegmatites within its Wyemandoo Project in Western Australia.
The ASX-lister is readying to investigate the nature of pegmatite mineralisation within Wyemandoo’s central Fairway Corridor after a sampling program in October.
During the program, Aldoro will hone in on the 'Loop Pegmatite' structure and its surrounds, where previous rock samples averaged 1.06% lithium oxide and 0.94% rubidium and up to 2.6% lithium oxide and 1.7% rubidium.
Ultimately, the target zone represents the epicentre of Wyemandoo’s lucrative Fairway Corridor, which contains highly anomalous lithium and rubidium rock chip samples.
In the past, satellite imagery has identified more than 1,000 dyke-like features within the corridor, firming up a key exploration target for the months to come.
Exploring Wyemandoo’s Fairway Corridor
Aldoro’s exploration campaign will sample the Wyemandoo Pegmatite Field at 30- and 40-metre intervals, providing valuable data to inform future drilling programs.
The company will also use a pXRF tool to pinpoint rubidium mineralisation at the property and expects to collect between 500 and 600 rock chip samples in the process.
An earlier review into the Wyemandoo Project’s pegmatites uncovered highly anomalous assays over nearly 9 kilometres of strike, paving the way for future exploration.
All up, the 52 pegmatite samples returned an average of 5,439 parts per million (ppm) rubidium, with one sampling reading 17,123 ppm.
In addition, the rock chip sampling program averaged 0.63% lithium oxide, with the highest result generating as much as 2.59%.
Wyemandoo’s pegmatite swarm appears to cover a large area — a northeast corridor over 10 kilometres long and up to six kilometres wide, where the full extent is masked by young alluvium and colluvium cover.
The project’s pegmatites generally trend northeast and can strike over 1,000 metres in length, varying from 1 metre to 20 metres in outcrop width with shallow to moderate dips.
Wyemandoo’s wider potential
Aldoro’s broader rare metals project sits just 80 kilometres south of Mount Magnet, covering 9 square kilometres.
It’s contiguous with another exploration tenement on the Narndee-Windimurra Igneous Complex.
So far, more than 20 pegmatite dykes have been mapped at Wyemandoo, of which 10 have been sampled.
Many more pegmatites cover the property, yet to be mapped or sampled.
