In 2024, China had the world’s largest reserves of natural graphite, at approximately 81 million metric tons. Graphite is a native element mineral and a semimetal, comprised of a crystalline allotrope of carbon. One of its well-known uses is as the lead in pencils. Global graphite production World graphite production has fluctuated slightly in recent years. In 2024, the total worldwide production of graphite amounted to 1.6 million metric tons, a slight decrease from the 1.68 million metric tons produced in the previous year. In the past decade, China has consistently been the leading global graphite producer. In 2024, China produced an estimated 1.27 million metric tons of graphite. Following China was Madagascar in a distant second place, with a production volume estimated at 89,000 metric tons that year. Global graphite market The global market value of graphite stood at about 23.7 billion U.S. dollars in 2022. This figure is expected to rise in the following years, reaching a market value of nearly 38 billion U.S. dollars in 2028 based on a compound annual growth rate of 8.01 percent between 2023 and 2028.

The point and polygon layers within this geodatabase present the global distribution of selected mineral resource features (deposits, mines, districts, mineral regions) for 22 minerals or mineral commodities considered critical to the economy and security of the United States as of 2017. These data complement the report by Schulz and others (2017) which provides national and global information on 23 critical minerals - antimony (Sb), barite (barium, Ba), beryllium (Be), cobalt (Co), fluorite or fluorspar (fluorine, F), gallium (Ga), germanium (Ge), graphite (carbon, C), hafnium (Hf), indium (In), lithium (Li), manganese (Mn), niobium (Nb), platinum-group elements (PGE), rare-earth elements (REE), rhenium (Re), selenium (Se), tantalum (Ta), tellurium (Te), tin (Sn), titanium (Ti), vanadium (V), and zirconium (Zr) resources. The geospatial locations for deposits containing selenium, which is recovered mainly as a byproduct of other produced mineral commodities, is not included in this geodatabase. These geospatial data and the accompanying report are an update to information published in 1973 in U.S. Geological Survey Professional Paper 820, United States Mineral Resources. For the current and full discussion of the individual critical minerals, their uses, identified resources, national and global distribution, geologic overview, resource assessment, and geoenvironmental considerations see: Schulz, K.J., DeYoung, J.H., Jr., Seal, R.R., II, and Bradley, D.C., eds., 2017, Critical mineral resources of the United States—Economic and environmental geology and prospects for future supply: U.S. Geological Survey Professional Paper 1802, 777 p., https://doi.org/10.3133/pp1802

This model is derived from geological, geophysical and other forms of geodata. Feature extraction used deep learning. Predictive modelling made use of the deep ensemble method. Displayed is a Pan-Canadian probability map of mineral potential of graphite. This map was generated using known graphite deposits and occurrences and their associated features. Higher probability values highlight areas with an increased probability of graphite mineral systems.

Critical minerals are a collection of metal and non-metal commodities considered essential for economic and industrial development, and for which there are significant concerns around future supply due to resource scarcity or geopolitical factors. The Geological Survey of South Australia's Critical Minerals South Australia (CMSA) project focuses on advancing knowledge to support critical minerals discovery and exploration in South Australia. The CMSA project, through the "Critical mineral potential of South Australia" report book series, reviews and identifies key mineralisation styles for defined critical minerals, maps existing critical mineral occurrences across the State and identifies regions with significant critical mineral potential aiming to increase industry and investor understanding of South Australia's critical mineral potential. The Report Book includes: - Overview of uses for graphite - Review of economic graphite deposit types - Graphite occurrences and prospectivity in South Australia - Maps of South Australia’s graphite occurrences and characteristic graphite forms - Excel spreadsheet combining all occurrence data for graphite available from South Australia’s Mineral Deposit (MinDep) database

Abstract This layer contains point locations of major mineral deposits, and includes the geological setting, the timing and type of mineralisation, global resource endowments, associated host and igneous rocks, alteration assemblages, and metamorphism, where known. The deposits were selected as they have substantial endowment (i.e. pre-mining mineral resource) and/or detailed geological information is available. For each deposit (or, in some cases, district) the dataset includes information on: 1. Name (including synonyms), location and GA identifying numbers; 2. Tectonic province that hosts the deposit; 3. Type(s) and age(s) of mineralising events that produced/affected the deposit (including metadata on ages); 4. The metal/mineral endowment of the deposit; 5. Host rocks to the deposit; 6. Spatially and/or temporally associated magmatic rocks; 7. Spatially and temporally associated alteration assemblages (mostly proximal, but, in some cases, regional assemblages); 8. The Fe-S-O minerals present in the deposit and relative abundances where known; 9. Sulfate minerals present; 10. Peak metamorphic grade; 11. Data sources; and 12. Comments. For many commodities, there are many hundreds or thousands of deposits and occurrences around Australia, with only a small fraction of these deposits/occurrences making a significant contribution to Australia’s mineral endowment. This dataset contains information about these deposits. In some cases, a number of small deposits have been grouped together into a district, but in other cases, small deposits have been ignored. However, where important information, such as the age of small deposits or occurrences are available, they have been included. This document presents more detailed descriptions of the metadata presented in the compilation. The dataset is presented in Appendix A. Appendix B presents a national classification of geological provinces based mostly on existing State survey classifications; Appendix C presents a deposit classification based on the classification proposed by Hofstra et al. (2021); and Appendix D presents mineral abbreviations used in the dataset. The Annexes are available here: Geological setting, age and endowment of major Australian mineral deposits - a compilation.

Metalogenetic map of the Czech Republic 1: 500,000 (V. Sattran et al., 1980) shows spatial and temporal distribution and description of individual genetic types of ore deposits and selected non-metallic raw materials (fluorite, barite, gypsum, graphite, magnesite, stone salt, etc.) on the geological and tectonic basis.

An upland area located approximately 100 km south-west of Whyalla on the eastern Eyre Peninsula, and with its eastern boundary running parallel to the coast at a distance of 15 km from Cowell and Franklin Harbour, is being explored for uranium,... An upland area located approximately 100 km south-west of Whyalla on the eastern Eyre Peninsula, and with its eastern boundary running parallel to the coast at a distance of 15 km from Cowell and Franklin Harbour, is being explored for uranium, graphite, manganese and iron ore. No field work was done during the first licence year. After UraniumSA bought the tenement, early exploration primarily addressed the potential for finding buried structurally controlled, high grade primary vein-type epigenetic uranium mineralisation in the Palaeoproterozoic basement rocks, and also possible younger, also buried unconformity style uranium mineralisation, similar in character to those deposits found in Canada's Athabasca Basin and the Alligator Rivers region of the Northern Territory in Australia. During January 2007, a reconnaissance ground IP survey using a 200 m x 100 m dipole-dipole array was acquired along three traverses located in the south-western part of the licence area, to profile the Blue Range Beds for chargeability anomalies. A number of these were detected and modelled for depth and intensity. During February 2007, part of an airborne magnetic/radiometric/digital terrain model survey was flown over the licence along NE-SW flight lines spaced 200 m apart, to generate 1352 line km of coverage. The aim of this survey was to assist in mapping probable buried faults and shear zones which could have related primary uranium mineralisation potential. Reconnaissance aircore drilling was performed in May 2007, of 113 vertical holes for a total penetration of 2063 m, both to test the causes of selected IP anomalies and to sample the underlying bedrock for lithology and geochemistry, as well as to map the thickness of the transported sedimentary cover. The aircore drilling found that the target Blue Range Beds had effectively been eroded away in the places tested, although some thin remnants of them were intersected in several holes, and there are small remnants outcropping at other localities. A shallow-sourced IP anomaly having associated bedrock copper and zinc anomalism was identified (the Boothby prospect). During licence Year 3, UraniumSA conducted further follow-up of the Boothby anomalies with soil calcrete geochemical sampling (384 samples assayed) to try to define the extent and orientation of the anomalism. A weak correlation was observed between the aircore drillhole bedrock sample geochemistry and the calcrete assay results, i.e. the trace element distribution displays a NW-SE trend, parallel to the strike of the Blue Range Beds, which also coincides to the present ground surface's general topographic drainage direction. In September 2008, during licence Year 4, UraniumSA acquired a small part of an airborne EM (RepTEM) survey over the Boothby prospect, flying 59.9 line km along eight east-west lines spaced at variable distances apart, using a 35 m mean sensor height above the ground surface. Again, the aim was to better define the extent and orientation of the anomalism prior to doing more drilling. No field work was done during the fifth licence year, while processing and interpetation of the whole 485 line km set of RepTEM survey data was effected. During 2011, under the alternate JV management of Pirie Resources, exploration on now renewed EL 4693 became focussed towards determining the manganese, iron ore and graphite potential of bedrock in the deeper, hinge zone section of the Campoona Syncline, which is buried mainly below >100 m thickness of cover. Previous company exploration results obtained from there were reviewed, and stored drillhole samples that contain graphite were sent for petrographic description. Another airborne EM (RepTEM) survey was flown during July 2011, of 156.5 line km along SE-NW orientated flight lines spaced either 100 m or 50 m apart, using a 30 m mean sensor height above the ground surface. Conductivity highs evident in the survey data were thought to correlate well with known graphite occurrences, while CDI sectional projections made of the data showed the syncline's structure well. On the basis of the subsurface geophysical mapping, 9 RAB holes for 451 m were drilled into two potential graphite-rich targets, Campoona South and Grid 2, during October 2011. Some other RAB drilling was done by Pirie Resources elsewhere on EL 4693 during February 2012, to test targets at Campoona West, Salt Creek, Emu Plain and ?Mangalo South-west [but no clear mention of these holes was provided to PIRSA by the company]. Late in 2011, two selected graphite schist samples, one a rock chip taken from weathered outcrop and the other of drill cuttings, were sent to overseas mineral processing experts for them to conduct laboratory testwork on separating the graphite grains and then determining the grain size distribution of the mineral concentrates. They reported that both the separated graphite fractions are predominantly very fine grained (less than 71 microns) and that the graphite in them is still mostly intergrown with mica. During licence Year 7, the majority of work performed by Pirie Resources consisted of a large appraisal and delineation drilling programme undertaken across the several graphite occurrences identified within the Campoona Syncline, in order to define a JORC Code-compliant estimated mineral resource. Drilling of 5 diamond holes and 37 RC holes at the Campoona Shaft and Campoona Central graphite occurrences provided data that were used as of September 2012 to estimate combined Measured, Indicated and Inferred resources, at a 5% Total Graphitic Carbon (TGC) lower cut-off grade, of 2.527 Mt containing 310,800 t of graphite. The individual resource category figures were also calculated [see main report]. Additional exploratory drilling, and a more detailed, prospect scale airborne EM survey, were also performed to define inferred strike extensions to the Campoona resource, as well as to try to identify other graphite occurrences amenable to extraction. A total of 113 inclined or vertical step-out RC holes were completed during the reporting period. Some material was identified further to the south as a part of the main occurrence trend, and some limited mineralisation was encountered to the north; both of these areas are affected by structural complexity, and follow-up drilling is necessary to understand the geology. Further metallurgical testwork on Campoona graphite mineral concentrates involving tailored grinding steps and advanced flotation methods was reported to have yielded upgraded graphite concentrates in excess of 98% TGC purity, a level of quality which Pirie Resources said is rare for an ultrafine natural graphite product. The capacity to produce such a quality product is expected to open up a wide range of market opportunities to the company for selling high grade concentrates (+95% & +99% TGC) at a generally higher market pricing. Also, Pirie Resources thinks that the economic so conferred by mining the Campoona material may allow the mining and processing of lower cut-off grades, larger reserves, and greater selectivity in mining. Consequently, many more resources may be available. In expectation of taking out a mining lease over the presently delineated resource areas, Pirie Resources commissioned consultants Golder Associates Pty Ltd to conduct baseline flora and fauna studies at Campoona during the period September to November 2012. In other important work, Pirie Resources' ground-based activities undertaken on the western side of EL 4693 have led to the discovery of a region of epithermally altered Hutchison Group basement rocks which the company has named the 'Donna Complex'. Interpretation of regional geophysical data supports a model of a deeply buried elongate intrusive igneous body underlying the region, which has overlying veined and brecciated hydrothermally altered zones formed on its north-western and south-eastern flanks. Sampling of the various altered country rocks has identified different styles of alteration related to the lithologies examined: - alunite alteration within what possibly were quartzites - silicification of dolomites - massive growth of tourmaline in pegmatites. Pictorial examples of these features are included in the 2012-2013 annual report. On the basis of this find, Pirie Resources' immediate intent was to begin exploring the region for epithermal gold via detailed geological mapping, surface geochemical sampling and other work necessary for defining deep drilling targets. Rock chip sampling was begun, and 180 samples were submitted for multielement analysis, with some significant minor gold results returned from the north-western breccias, and a general spread of elevated base metal anomalism. During licence Year 8, Pirie Resources' main activity was to perform an infill drilling campaign at the Campoona Syncline graphite occurrence to define a maiden inferred JORC-compliant resource at the Campoona Central deposit. For this, 28 angled RC holes for 1447 m plus one 60 m deep steeply inclined HQ diamond hole were completed. Using a 5% Total Graphitic Carbon (TGC) lower cut-off grade, a resource of 520,000 t of graphite was estimated. At the Campoona Shaft deposit, geotechnical drilling of 3 angled HQ diamond holes for 297 m plus 4 vertical 9 inch auger holes for 120 m was undertaken respectively to investigate ground conditions to inform mine planning studies, and to obtain a larger volume of rock material to use for future metallurgical testwork. For epithermal gold exploration, bedrock geochemical drilling of 2 angled RC holes for 139 m was performed at Bartels prospect to try to find additional vectors towards mineralisation. Further rock chip geochemical sampling was done at the

Excel spreadsheet summarising thin sectioned samples collected from the Southern Prince Charles Mountains in the 1970's by Geoscience Australia geologists. Each sample is briefly described by fields identifying primary and secondary mineral abundance. The most common primary mineral is ID by 1.1, the second most common mineral by 1.2, and so on. Similarly, secondary minerals are ID by 2.1, 2.2 etc. Secondary minerals can be those formed by either alteration or later metamorphic events.

This spreadsheet was to form the basis for an interactive GIS summarising the petrology of the Prince Charles Mountains. A similar project had been undertaken by the author for a Metallogenic Atlas of the Pine Creek Region in the Northern Territory, Australia (refer Geoscience Australia).

Thin Sections are held at Geoscience Australia.

The Geographic Information System (GIS) point layer, Abandoned Mines of New Jersey contains locations and attributes for abandoned mines. The shapefile has locations for nine types of abandoned mines which are Copper, Graphite, Iron, Lead, Mica, Manganese, Sulfide, Uranium and Zinc. There are 588 abandoned mine locations in the database and they are mapped at a scale of 1:24,000. This updated version of the data has undergone significant changes in two USGS quadrangles since the previous version of this data, dated July 29, 2005, was published. Previously, Bloomsbury, Blairstown, Easton, and High Bridge USGS quadrangles were updated. In this update, field work by geologists was conducted to improve the locational information of the mines in the Franklin and Riegelsville USGS quadrangles. Some of the mines in these quadrangles were located using the global positioning system (GPS). Certain mines in these quadrangles were mapped for the first time and appear in this data but not in the previous version of the data. Some known mine locations in the previous version of the data have been more accurately mapped and the points have been relocated.
