FIRST ASSAY RESULTS FROM PHASE 1 DRILLING CONFIRMS LITHIUM
MINERALISATION UNDER THE A$12 MILLION SQM EARN IN AGREEMENT
Dart Mining NL (ASXTM) (“Dart Mining” or “the Company”) has received the first assay batch from 3 of
the 12 holes forming part of the Phase 1 diamond drilling under the A$12 million SQM earn in agreement
(Dart ASX July 2022) with Dart Mining. Initial assay data from 3 holes in the program show peak results up
to 0.81m @ 1.2% Li2O and 0.62m @ 1.6% Li2O along with wider intervals of low grade lithium
mineralisation. These initial results come from only two dykes of the five dykes tested, and further
underpins the LCT dyke prospectivity of the Dorchap Dyke Swarm. The Phase 1 drill program has recently
been completed for a total of 3032m (3000m planned) into 5 dyke targets across 12 holes with planning
and permitting for the Phase 2 drill program already well advanced.

• Spodumene mineralisation indicated in Fergusson Dyke (MIDDH005) and Petalite &
Eucryptite mineralisation identified in Eagle Dyke (MIDDH001 & MIDDH002)
• Multiple dykes intercepted in MIDDH001 and MIDDH002 at Eagle Dyke
• Assay results from MIDDH001 include:
o 17.77m @ 0.16% Li2O (exomorphic halo)
o 12.66m @ 0.10% Li2O (pegmatite dyke)
o 5.2m @ 0.11% Li2O (exomorphic halo)
o 4.92m @ 0.10% Li2O (exomorphic halo)
o 8.76m @ 0.08% Li2O (pegmatite dyke)
o 7.9m @ 0.11% Li2O (exomorphic halo)

• Assay results from MIDDH002 include:
o 0.98m @ 0.20% Li2O (exomorphic halo)
o 16.75m @ 0.21% Li2O (pegmatite dyke), inc. 0.81m @ 1.2% LiO2
o 1.58m @ 0.36% Li2O (exomorphic halo)
o 8.77m @ 0.10% Li2O (exomorphic halo)

• Single pegmatite intercepted at Fergusson’s Dyke in MIDDH005
o 0.49m @ 0.17% Li2O (exomorphic halo)
o 3.01m @ 0.26% Li2O (pegmatite dyke), inc. 0.62m @ 1.63% LiO2
o 1.88m @ 0.11% Li2O (exomorphic halo)

Chairman, James Chirnside commented: “These results are from the first 3 holes in the 12 hole Phase 1
diamond drilling program. These initial results confirm lithium mineralisation at depth within these dykes,
and further defines the structural and mineralogical characteristics of this dyke system. The identification
of spodumene in drill core is very promising, and we look forward to further assay results as they become
available.”
