Significant lithium soil results at Trigg Hill Project

Jane Morgan Management


  • Soil samples in East Curlew area return strongly anomalous Li, Ta, Sn
  • Soil results up to 517ppm Li2O, 95ppm Ta2O5 and 922ppm SnO2
  • Highlights potential of pegmatites not mapped or sampled

Eastern Resources Limited (ASX:EFE) (“Eastern Resources” or the “Company”) is pleased to announce recent soil samples from Trigg Hill Lithium-Tantalum Project (“Project”) which returned elevated levels of lithium (Li), tantalum (Ta), tin (Sn), caesium (Cs), rubidium (Rb) and niobium (Nb).

The Company conducted an initial soil sampling program in April and May 2022 as a first stage assessment over the Curlew East pegmatite swarm. The soil sampling program comprised 226 samples from an area 1.6km by1.9km.

The western Li +/- Ta, Sn, Cs (LCT) soil anomaly is coincident with recent rock chip samples results (refer to the Company announcement dated 8 July 2022 and Figure 1). A second larger LCT soil anomaly is located further to the east and pegmatites in this area have essentially not been mapped or rock ship sampled.

A third large Sn, Ta, Rb anomaly occurs in the eastern part of the tenement and is related to pegmatite swarms within granite and therefore not a priority target.

There appears to be a strong east to south-easterly trend to the strongest LCT soil anomalism. The initial soil sampling program has been successful in defining areas to focus detailed mapping rock chip sampling.

Executive Director Myles Fang commented: “We are very pleased with the results from this initial soil sampling program at Trigg Hill. The East Curlew LCT pegmatite swarm appears to be much larger than originally anticipated with strong geochemistry over a large area. The proposed initial drill program will provide information on pegmatite density, orientation and mineralogy.”

Next Steps

A 2,000m RC drilling program has been planned, with additional mapping programs also planned to expand on the initial soil program in the coming months.

Key Facts:

Trigg Hill Lithium-Tantalum Project

The Trigg Hill Lithium-Tantalum Project is located in East Pilbara, Western Australia, approximately 75km SE of Pilbara Minerals Ltd’s Pilgangoora Lithium mine.

The Trigg Hill mine is an old tantalum and tin mine operated during the 1960s and early 1980s. A Significant number of pegmatite outcrops were mapped over an area of 3km strike by up to 1.2km in the Project, including the East Curlew Lithium-caesium-tantalum (“LCT”) pegmatite, which extends for at least 1,800m.

The Company executed a binding Heads of Agreement to acquire 100% interest in the Trigg Hill Project (refer ASX Announcement 4 August 2021).
