Minerals 260 Limited (ASX: MI6) has identified lithium potential at the 100%-owned Aston Project in Western Australia through initial soil sampling assay results from the ongoing maiden exploration programme.
Results for 1,879 regional and infill soil samples have confirmed strong lithium (+tantalum and rubidium) anomalism (>100ppm Li2O) coincident with stream anomalism.
Two large lithium anomalies are defined, a ~5.2 x 0.2km anomaly along the Jamesons-Malinda trend, and a 3.0 x 1.9km anomaly north of the historic Nardoo Well mining centre. The anomalies average ~125ppm Li2O, roughly three times background, with a maximum value of 232ppm Li2O.
The Jamesons-Malinda lithium anomaly is coincident with the southern margin of the Leake Spring Metamorphics, the host of Delta Lithium’s Malinda and Jamesons Prospects. The Nardoo Well Mining Centre anomaly, hosted in Thirty-Three Supersuite granites, is coincident with known pegmatite occurrences previously mined for tantalum, niobium, beryl and mica.
Results from the third infill grid located in the southwest part of the Project, and additional regional soil samples, are pending and expected in the coming weeks.
As reported previously, the current field programme, which is designed to define drill targets, will take approximately six months to complete and comprises:
- Reconnaissance (500x500m) and infill (400x50m) soil sampling.
- Geological reconnaissance including rock chip sampling.
- A high-resolution airborne magnetic and radiometric survey over the ~50% of the area for which the data was not available when the Project was acquired.
“The results announced today are very positive and support the decision to acquire the significant tenement holdings earlier this year in what is looking like becoming an exciting area to be for Australia’s next wave of potential lithium companies.” Chief Executive Officer, Luke McFadyen, said.
