Green Critical Minerals Limited announced updates for the Mcintosh Graphite Project Exploration Target. This announcement is a revision of the Company's 22 February 2023 announcement `Maiden drill program planned at ultra-high purity McIntosh graphite project'. It includes a revised exploration target and accompanying JORC Table 1 based on a complete review of all the historical McIntosh Graphite Project data and includes GCM's recent mapping and rock chip sampling data.Green Critical Minerals Pty Ltd. ("GCM" or "the Company") which holds earn-in rights for up to 80% of the advanced Ultra High Purity /High Quality McIntosh Graphite Project reported the review and definition of an Exploration Target for the company's McIntosh Graphite Project ("the Project"), situated in the East Kimberley region, approximately 90 km north- northeast of Halls Creek, Western Australia.

GCM has undertaken an update of the McIntosh Graphite Project's exploration target to incorporate the latest field observations and rock chip samples. An Exploration Target has been calculated of 67.2 million tonnes up to 100.9 million tonnes, with an average grade ranging from 2.0 to 5.0% total graphiticcarbon (TGC). The potential quantity and grade is conceptual in nature.

There has been insufficient exploration to define a mineral resource at the Project and it is uncertain in further exploration will result in the target being delineated as a mineral resource. Compared to the previous exploration targets, there have been some changes based on the recent field mapping of outcrop thickness resulting in Marlin's size being reduced and Cobia's size increasing. Moreover, Mahi and Threadfin have been reintroduced as exploration targets since their flake size is deemed appropriate for SPG potential, as per GCM's announcement 01/12/2022 regarding SPG battery anode potential at the McIntosh project.

Overall, while the target size has remained largely the same, GCM now has increased confidence regarding the potential for future growth and look forward to updating the market with results from upcoming drill program in Second Quarter 2023. The independently estimated Exploration Target was calculated using a combination of exploration data, including geological mapping and rock chip geochemistry from a recent field program conducted on behalf of GCM, as well as historical drill data and geophysical modelling of EM data collected from the Lamboo VTEM survey conducted in 2014 and the Xcite VTEM survey conducted in 2016.Notable geochemical results from the recent rock chip sampling program include: Marlin West - 5.73%, 4.96% and 4.98% TGC Threadfin - 6.76%, 5.3%, and 4.39% TGC Trevally 4.94%, 3.32% and 3.08% TGC Cobia -6.65%, 4.72% and 4.52% TGC. The data generated from the 2014 VTEM Lamboo geophysical survey and 2016 VTEM Xcite geophysical survey were processed, interpreted, and modelled by Southern Geoscience Consultants (SGC).

The EM highs delineated in the geophysical surveys are a critical exploration tool as the graphitic mineralisation is highly conductive and presents itself with this tenor of response. Anomalous areas presenting a strong EM response were modelled as EM plates and were utilized to determine the geometry of potential graphite mineralisation; this correlation is supported by rock chip geochemistry, field mapping and drill results The Exploration Target is based upon mineralisation horizons that were constructed using the results of historical drilling and modelled EM plates. Where drilling is present, section by section geological and mineralisation interpretations was conducted and grade envelopes constructed to calculate a volume and average grade of TGC.

The graphite at the McIntosh Project is hosted in graphite schist horizons of the Tickalara Metamorphics. A nominal density of 2.8 t/m3 was used to convert volumes to tonnes, this value was based on density measurement from drill samples from Emperor, Wahoo, Longtom, Barracuda (oxide density = 2.7 t/m3; fresh density = 2.9 t/m3). For the conceptual estimate, the range of elemental TGC is provided by multiplying the mean volume, nominal density, calculated tonnes and nominal graphite concentration of the Exploration Target by +/- 20%.
