Asset Fields
Global Mining Dataset standardises information from multiple underlying sources into a common set of asset fields. These fields are used throughout the platform for searchm, filtering, screening and exports. Field availability varies by asset depending on the information avaliable from the underlying sources.

Site data
Every asset is representated by a single publishable record within Global MIning Dataset. The identificaiton fields provide the basic information used to distinguish that asset and connect records that may use different names across underlying sources.
Mining assets frequently have multiple names. A project may be renamed as it develops, different sources may use local or historical names, and a mine and it's underlying deposit may be described differently. Where appropriate, Global Mining Dataset retains these alternative names while providing a consistent primary name for use throughout the platform
| Field name | Description | Format | Example |
|---|---|---|---|
| Asset name | Primary name used to identify the asset within Global Mining Dataset | Text | Escondida |
| Alternative names | Other known names, including historical names, project names, and source-specific variations | List | Minera, Escondida, Escondida mine |
| Asset ID | Unique identifier assigned to the asset within Global Mining Dataset | UID | GMD-0012345 |
Location
Location is fundamental to how Global Mining Dataset works. Each asset is assigned a published geographic location which is used both to display the asset and to calculate its surrounding geospatial context.
Coordinates are compiled from the avaliable source evidence and can vary in precision. Some sources provide precise mine or project locations, while others may identify a broader deposit prospect or approximate location. Where there are multiple locations for the same asset the highest quality source is used, and where information is conflicting the centroid location between the sources is used.
| Field name | Description | Format | Example |
|---|---|---|---|
| Country ISO | Country ISO cost used to identify which country the asset is located | Text | CHL |
| Coordinates | Unique identifier assigned to the asset within Global Mining Dataset | Decimal numbers | (-24.2667, -69.0067) |
| Estimated mine area | Estimated area of the mining operation where polygon data is available | Area (Square kilometers) | 7.34 |
Location confidence: Where available, location confidence provides additional context on the quality of the geographic evidence behind an asset. It is particularly useful when assessing result based on nearby infrastructure, settlements or other highly localised features.
Commodity information
Commodity infomation describes the minerals associated with an asset. Because underlying datasets use different terminology and levels of detail, commodity names are standardised to make filtering and comparison possible across the wider asset universe.
The primary commodity refers to the Assets can be associated with more then one commodity. A commodity association does not necessarily mean that the commodity is currently being produced or that it represents an economically recoverable resource.
| Field name | Description | Format | Example |
|---|---|---|---|
| Primary commodity | Principal commodity associated with the asset, where one can be determined name used to identify the asset within Global Mining Dataset | Text | Copper |
| Secondary commodities | All commodities associated with the asset in the available source information | List | Gold, Silver |
Asset classification
Asset classificaiton provides a broad indication of what kind of site a record represents. This is im;portant because the Asset Universe extends beyond currently operating mines to include development projects, prospects and other mineral assets.
These classifications provde a consistent way to navigate a diverse global dataset rather than attempting to impose a detailed mine-development taxononmy across every jurisdiction and source
| Field name | Description | Format | Example |
|---|---|---|---|
| Asset type | Principal commodity associated with the asset, where one can be determined name used to identify the asset within Global Mining Dataset | Text | Open pit mine |
| Status | Current known operating or development state of the asset | Text | Operating |
Asset type
| Value | Meaning |
|---|---|
| Mine | A mining operation where the available information does not support a more specific extraction type |
| Open pit mine | A surface mining operation where material is extracted from an open excavation or pit |
| Surface mine | A mining operation using surface extraction methods where a more specific survace mining classificaiton is not available |
| Placer mine | A mining operation extracting minerals from alluvial or other unconsolidated deposits, typically using gravity-based separation methods |
| Occurrance | Current known operating or development state of the asset |
| Underground mine | A mining operation where the mineral deposit is accessed and extracted primarily through underground workings |
| Smelter | A processing facility that uses high-temperature treatment to extract ior produce metal from ores, concentrates or intermediate products |
| Refinery | A facility that further processes or purifies mineral or metal products into a higher-purity form |
Asset types in the real world: Asset types are not necessarily mutually exclusive. A mining complex may, for example, contain both open pit and underground operations alongside processing facilities. The published asset type represents the classificaiton applied to the individual record within Global Mining Dataset.
Status
Status describes the current known operating or development state of an asset. It provides a consistent way to distinguish existing operaitons from projects under development and assets that are no longer activley operating.
Status can change significantly over the life of an asset and, in some fast, faster than the underlying public sources are updated. The published status therefore be interpreted as the best available classification based on the evidence available to Global Mining Dataset
| Value | Meaning |
|---|---|
| Operating | The asset is reported to be actively operating or producing |
| Devlopment | The asset is being evaluated or progressed towards potential operation but has not yet entered construction |
| Construction | The asset is reported to be under construciton or undergoing material development ahead of operation |
| Care and maintenance | Operations have been suspended, but the asset is being maintained with the potential to restart |
| Inactive | The asset is not currently operating and is not known to be in active construction or development |
| Closed | Operations at the asset are reported to have ceased or the asset has been formally closed |
| Unknown | Available evidence is insufficient to assign a reliabe current status |
Interpreting status: Different classifications answer different research questions: Operating assets can be used to understand current mining activity, while development and construction assets can provide a view of potential future projects or supply. Inactive, care and maintenance, and closed assets remain within the asset universe because they can still be relevant for historical analysis, restart opportunities, regional research and understanding existing mining footprints.
Ownership
Ownership information helps users understand the companies and organisations associated with an asset. This can support company level research, portfolio analysis, competitive mapping, and identification of assets associated with particular operators or owners.
Ownership structures can be complex and change over time. Coverage also varies significatn;y between underlying sources, partocularly for earlier-stage assets. Owenership information should therefore be considrerd alongside the source and date of the available evidence.
| Field name | Description | Format | Example |
|---|---|---|---|
| Current owner | Company or organisation identified as having primary ownership interest in the asset. | Text | BHP |
| Previous owners | All commodities associated with the asset in the available source information | List | Minera Utah de Chile |
| Operating history | Reported opening and closure dates for the mine during it's operating history, note it's common for mines to open and close multiple times during it's lifespan correlated with economic performance of the primary commodity | List of dates | 1962 to 1974, 2022 to current |
