Carbon speciation data include total carbon, total inorganic carbon, total organic carbon and total graphitic carbon data. Graphitic carbon content is a key parameter for assessing graphite quality and potential economic value. The report also presents Rock-Eval pyrolysis data with their associated pyrolysis and oxidation thermograms, which are complementary to the carbon speciation data. These data form part of a drill core analytical program undertaken as part of the Birrindudu Deep Dive project. This project is delivered under the Resourcing Australia's Prosperity initiative, the Australian Government's 35 year (2024-2059), precompetitive geoscience initiative led by Geoscience Australia. Its purpose is to accelerate the discovery and responsible development of Australia's critical minerals, strategic materials, hydrogen, carbon dioxide storage, offshore renewable energy and groundwater resources.

These data form part of of a broader drill core analytical program undertaken within the Birrindudu Deep Dive region, including drill holes from the McArthur Basin. The Birrindudu Deep Dive covers multiple geological provinces of varying age and assesses their potential to support economically sustainable resources, agriculture, and social outcomes for regional and remote communities. This project is delivered under the Resourcing Australia's Prosperity initiative, which supports Australia's long-term resource security and transition to net zero by 2050 by providing enhanced pre-competitive geoscience data, scientific analysis and decision-support tools to underpin resource exploration and the responsible management of Australia's resources.

The samples were from various project areas in the Northern Territory, which from an email heading appeared to be Maryfield, Broadmere and Dunmarra.; The samples comprised small pieces of drill core (few centimetres of generally less than half core), with some stated to contain small amounts of sulphide minerals and some containing anomalous metal values. Samples were labelled Marmbulligan 1 @409.76 m, NDW12-01 @307.1 m, NDW12-01 @307.15 m, VDD2 @203.85 m, VDD2 @205.1 m, 12LE001 @131.9 m and DDH08 @183.1 m.; The purpose of the petrographic work was to identify the primary rock types and imposed processes that included diagenetic alteration and local sulphide mineralisation.
