The two distinct REE (rare earth element) anomalies were discovered in the northern and southern sections of the tenement, with the former identified during lithium exploration and the latter through a review of historic auger surveying from AngloGold Ashanti.
A peak value of 1693ppm (parts per million) TREO (total rare earth oxides) was determined within a 1.8km long, >400ppm TREO anomaly from AngloGold auger samples.
AngloGold’s auger geochemistry program was primarily targeting gold and was undertaken in several phases over a wide area between Norseman and Esperance between 2009 and 2013.
Larvotto managing director Ron Heeks said the Eyre project continues to surprise.
“These results again highlight the amazing range of mineralisation that is evident at our Eyre project,” he said.
“In addition to the nickel, copper, PGE (platinum group elements) and lithium anomalies we have previously reported, we have now identified two very interesting REE anomalies generated from different sources.”
The Albany Fraser terrain, in which the southern anomaly is located, is becoming more and more active for REE exploration.
Heeks said the AngloGold data has proven an effective targeting tool, with Larvotto not the only company to benefit from the historical results.
The northern anomaly closely tracks the western boundary of a high magnetic unit, thought to be comprised of ultramafic rocks. Values of up to 171ppm TREO have been recorded within a 1.8km long, >120ppm TREO anomaly.
Larvotto said it plans to complete an infill auger program to further delineate the anomalies prior to RAB (rotary air blast) drilling.
