# Own-account mineral exploration and evaluation information

## 1. Scope and Applicability

This PCR covers creation on own account of identifiable mineral exploration and evaluation information assets for solid minerals, petroleum and natural gas, including initial exploration and distinct subsequent re-evaluation. The owner may retain, sell or license the information. The reference object is original knowledge about a declared deposit/prospect and evaluation stage, not a generic consulting hour, a discovered deposit or a mining licence (un-cpc3-exploration). Include all actual investigation routes, including unsuccessful work, contributing to that original.

Exclude standalone commissioned geological consulting, geophysical or drilling services as reference products; these may be inputs. Exclude routine mining/production drilling, commercial extraction and beneficiation, the natural resource stock, licence/right transactions, generic R&D originals, software originals, generic databases, branding, broadcasts and downloads. Geographical evidence and an interpretation model integrated in the exploration asset are components; independent software/data assets retain distinct inventories. No requirement that the original discovers an economic reserve. A one-item inventory is meaningful only with its scope and quality; unrelated projects are not equivalent.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_count | reference product | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | item | Record exactly one complete version using cp_original; item is Item(s) with factor 1. Do not invent a physical mass or infer output count from revenue, reserves or bytes. |
| same_basis | all inventory rows | Original package count | item | Use per declared reference flow for every row and protocol; keep each exchange numerator in its physical unit. |
| electricity_conversion | all electricity rows | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Preserve the public reference property. Convert measured kWh to MJ with 1 kWh = 3.6 MJ. Match the meter boundary; do not convert storage GB, network GB or CPU hours directly into kWh. |
| physical_state | drilling_fluid, tap_water, diesel | Volume or Mass as the specific identity declares | m3 or kg | Retain primary property: drilling fluid Volume/m3, tap water and diesel Mass/kg. A measured volume-to-mass conversion requires actual composition, temperature and measured density; no generic density. |

Mass `93a60a56-a3c8-11da-a746-0800200b9a66` references Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` (kg); Volume `93a60a56-a3c8-22da-a746-0800200c9a66` references Units of volume `93a60a57-a3c8-12da-a746-0800200c9a66` (m3); Net calorific value references Units of energy `93a60a57-a3c8-11da-a746-0800200c9a66` (MJ). These properties concern exchanges, not information mass.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Identified project inception or re-evaluation start, existing evidence and actual ownership/supplied state |
| starting_condition_role | Foreground original-asset creation, not resource extraction |
| product_classification_scope | Own-account exploration and evaluation information; geographical/method scope declared |
| recursive_input_rule | Reused prior exploration original is a distinct input with provenance and carried allocated upstream burden. Do not recursively reconstruct or duplicate its original creation in the new version. |
| upstream_dataset_requirement | Require compatible utility/material/equipment/service datasets with supplier, region, year, configuration and boundary. Missing layers remain disclosed cutoffs. |
| disclosure | Full project route, unsuccessful work, make/buy ledger, historical inputs, transport, facilities, closure, initial storage/transfer and exclusions. Foreground-only is not complete cradle-to-gate. |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| boundary_project | all processes | Include attributable planning, investigation, analysis, interpretation and documentation through original completion, including failed holes and inconclusive tests. Physical transport, camps, heating/cooling and initial delivery actually used require individually measured exchanges, not salaries or financial licence fees. | un-cpc3-exploration; un-sna2008-exploration |
| boundary_route | survey, drilling, analysis | Record the actual route register before using conditional cards. Include geological mapping, geochemical/geophysical work, aerial or marine surveys, drilling and appraisal tests only when performed. Extend cards for every actual fuel, reagent, sample container, well material, waste and supported release; absent required route evidence blocks completeness. | un-sna2008-exploration; jorc2012-reporting |
| boundary_make_buy | all processes | Subdivide direct operation from purchased complete service. Supplier reports are technical inputs, not a second exploration original. Do not add embedded provider fuel/electricity/equipment; lacking supplier inventories remain unknown. Own laboratories require actual assay-specific physical inventories. | jorc2012-reporting |
| boundary_reuse | completion | Separate original creation from later copying, download, licence administration, hosting/network operation and mine development/use. Initial measured packaging/storage/transfer may be included with an explicit cutoff; no presumed lifetime, data centre or GB-to-energy factor. | un-cpc3-exploration |
| boundary_disturbance | infrastructure | Include actual exploration disturbance, restoration and residual obligations attributable to this project; specify area, duration, prior/after land state, hole sealing and water handling. Do not classify exploration pads automatically as commercial mineral extraction land. No mine-closure burden or generic land/emission factor is assumed. | un-sna2008-exploration |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| planning | Project definition and existing-evidence appraisal | required | All originals | foreground creation or allocated support | per declared reference flow |
| survey | Field surveying and sampling | conditional | Actual geological, geochemical, geophysical, aerial or marine survey | foreground creation or allocated support | per declared reference flow |
| drilling | Exploratory drilling and test work | conditional | Actual test drilling, boring, trenching or appraisal tests | foreground creation or allocated support | per declared reference flow |
| analysis | Sample analysis and quality control | conditional | Actual sample preparation and analytical testing | foreground creation or allocated support | per declared reference flow |
| evaluation | Interpretation and evaluation | required | All originals; evaluation depth declared | foreground creation or allocated support | per declared reference flow |
| completion | Original information completion and initial handover | required | All originals | foreground creation or allocated support | per declared reference flow |
| infrastructure | Allocated equipment manufacture and exploration closure | conditional | Attributable equipment and disturbed sites | foreground creation or allocated support | per declared reference flow |

Conditional cards describe specific exchanges, not a universal drilling or assay recipe. Project maps must cover every actual method including petroleum/natural gas geophysics and appraisal, not merely the water-based solid-mineral example. Missing route rows or supplier inventories prevent a complete dataset claim. Internal sample and draft transfers cancel in the consolidated original inventory; retained samples are not market co-products.

| allocation_project | all processes | Directly attribute identifiable site, hole, assay, computing and documentation records to the original. Subdivide unrelated mining production and other originals first. For shared work use measured causal utilisation with a documented beneficiary ledger; disclose residuals and test sensitivity when causation is uncertain. No allocation by mineral value, revenue, licence price or presumed discovery success. | un-sna2008-exploration |
| allocation_original | reference_product | An original is created once. Reuse in a new evaluation carries an explicitly documented share of the prior asset inventory; copies and licences do not recreate it. Failed or negative investigations contributing to the defined information belong to that package; abandoned separate projects retain their own burdens, not a zero-success disposal to future mining. | un-cpc3-exploration; un-sna2008-exploration |
| allocation_equipment | infrastructure | Use actual configuration and traceable whole-life utilisation for owned equipment manufacture/end-of-life. Meter shared facility/compute electricity or use a validated site workload allocation, including idle and overhead shares. Do not assume all equipment is new or infer electricity from job duration alone. Treat waste as waste unless a real market product and consistent allocation are demonstrated. | un-sna2008-exploration |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| project_aggregation | all inventory rows | Sum nonduplicated measured exchange amounts attributable to this one original and express per declared reference flow. Shared measured shares precede consolidation; reference output is 1 item. Preserve each numerator unit. | cp_original; cp_energy; cp_material; cp_services; cp_waste; cp_emission; cp_water; cp_equipment | per declared reference flow | un-cpc3-exploration |
| energy_conversion | all electricity rows | Multiply recorded attributable kWh by 3.6 to express MJ at the same interface. No additional conversion of original count. | cp_energy | MJ |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_scope | reference_product | Original identity and version, own-account nature, geospatial/depth/commodity scope and acceptance must be verifiable. Report unavailable data and uncertainty. | cp_original; un-cpc3-exploration |
| quality_geology | survey; drilling; analysis; evaluation | For solid-mineral routes retain sample representativity/recovery, drill method, assay precision/bias, coordinates, compositing and interpretation confidence; JORC Table 1 is scoped reporting guidance, not LCA approval. Oil/gas needs its actual reservoir/seismic/well evaluation evidence and applicable regime; do not label it JORC certified. | cp_services; jorc2012-reporting |
| quality_inventory | all inventory rows | No default fuel use, composition, assay recipe, lifetime, emission factor, water return or net output. Require actual records, missing layer disclosure and cut-off sensitivity. Historic evidence defines concepts only unless demonstrated representative of the current project. | all collection protocols |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_identity | reference_product | Require exact one-item output link/name, declared version and qualifiers, provenance and ownership. Candidate unresolved identities are disclosed; they are not verified product providers or methodology approval. | un-cpc3-exploration |
| validate_scope | all processes | Reconcile every actual survey, borehole, test, failed branch, assay, transport, computation, delivery and closure with process coverage and make/buy ledger. Unknown provider/route inventories make lifecycle completeness inconclusive. | un-sna2008-exploration |
| validate_measurement | all inventory rows | Require consistent per declared reference flow, complete protocols, numerator units, energy/density conversions, shared shares and stock balances in both languages. Do not normalize information by kg or money. |  |
| validate_release | all elementary and waste rows | Require demonstrated occurrence and species/physical identity for every elementary or waste exchange. For direct elementary emissions, require medium/submedium and immediate/long-term distinction; require fossil/biogenic origin for carbon emissions. For river-water withdrawal, retain river/basin, intake date and volume, and separate return location, volume and quality. For technosphere waste transfers, retain composition/state, amount, destination and transfer records. Waste fluid is not environmental water. Never silently set unavailable emissions to zero or use total NOx as molecular NO2. Use `cp_emission`, `cp_water` and `cp_waste` for the respective emission, water-withdrawal and waste-transfer evidence. |  |

## 10. Published Dataset Profile

| --- | --- |
| dataset_role | foreground_dataset |

| allowed_use | Original information creation inventory for declared scope; use as an allocated input to a later evaluation or mining study with explicit reuse ledger |
| excluded_use | Reserve valuation/certification; universal per-tonne mining factor; service-hour benchmark; per-copy/download burden without reuse accounting; complete lifecycle claim with unresolved layers |
| required_metadata | All reference qualifiers; geography/year; actual routes; meter/supplier boundaries; stock and allocation ledgers; units; original evidence; provider compatibility |
| required_quality_disclosure | Accepted input; checks performed/skipped; completeness; findings; geology uncertainty; failed work; missing UUID/providers; historical evidence limitations; cutoff sensitivity |
| update_trigger | New version, area/depth/commodity or evaluation stage; changed evidence, route, provider, method, rights or allocation |
