Dorchap Lithium Update

Formation of the Technical Advisory Committee (TAC), containing representatives from Dart Mining and Sociedad Química y Minera de Chile S.A (SQM) is an essential first step in reviewing the project and the work programs for the development of exploration targets. The TAC has jointly outlined an initial six-month exploration work program. This exploration program will comprise surface rock chip sampling from prospective pegmatites identified in LiDAR data ( DTM ASX October 2021 ), run in tandem with an initial diamond drill program to assess previously identified, roadside and near-road side lithium-bearing pegmatite dykes. Rock chip sampling has commenced, and we are currently undergoing the permitting and approvals process to begin a low impact exploration diamond drilling assessment of accessible lithium-bearing targets, scheduled to begin in 2023.

Additionally, Dart Mining has received notification from Earth Resources Regulation Victoria that exploration licences EL5315 (Mitta), EL006277 (Empress), and EL006300 (Eskdale) have each been renewed for a period of five years, providing assurance of tenure across the Dorchap Lithium Project.

Chairman, James Chirnside commented: “The formation of the technical advisory committee marks the first step in our relationship with our fully funded earn-in joint venture partners, SQM. The TAC is critical for the establishment of a systematic and deliberate exploration approach and will help in the acceleration of further exploration of the Dorchap Lithium Project. Extended tenure of the critical Exploration Licences is very constructive, and we are eager to progress surface sampling and drill testing of this highly prospective Lithium project.”
