Mining, Quarrying & Oil and Gas Extraction Industry Classification Codes (SIC & NAICS)
Mining, Quarrying & Oil and Gas Extraction Industry Codes
Updated: 2025
The Mining, Quarrying & Oil and Gas Extraction sector includes establishments engaged in exploring for, developing, and extracting minerals, fossil fuels, and other geologic materials. This sector covers metal mining, coal mining, oil and gas drilling, support activities, and the extraction of nonmetallic minerals such as stone, sand, and clay. These classifications support resource assessment, environmental permitting, commodity market analysis, energy forecasting, and regulatory oversight. Accurate SIC and NAICS codes ensure consistent rollups for production reporting, reserve estimation, and supply chain analysis across global resource industries.
SIC Range: 10–14
NAICS Range: 21
SICCODE.com assigns industries to this sector when their primary activity involves exploration, drilling, mining, quarrying, or extraction of mineral, metallic, fossil fuel, or nonmetallic geologic resources, or when they provide core support services to those activities. SIC codes are included when extraction or resource development, rather than manufacturing or distribution, is the central economic function.
SIC vs. NAICS Structure for Mining, Quarrying & Oil & Gas
| SIC Structure | NAICS Structure |
| Mining is divided into four primary groups: metal mining, coal mining, oil and gas extraction, and nonmetallic mineral extraction (stone, sand, gravel, clay, and other industrial minerals). | NAICS 21 groups all resource extraction industries into a single sector, with detailed industries for oil and gas extraction, coal mining, metal ore mining, nonmetallic mineral mining and quarrying, and support activities. |
| SIC emphasizes the resource type (metal, coal, oil and gas, nonmetallic minerals) and traditional mine, well, and quarry operations. | NAICS adds structure around contract drilling, exploration, and support services, helping isolate field services and specialized contractors from operating producers. |
| Support and contract services are often embedded within broader mining categories, making it harder to separate service providers from producers. | NAICS defines “Support Activities for Mining” as a distinct group, enabling clearer regulatory reporting, safety analysis, and vendor segmentation. |
Major SIC Subsectors (Linked to Official 2-Digit Pages)
- SIC 10 — Metal Mining
- SIC 12 — Bituminous Coal & Lignite Mining
- SIC 13 — Oil & Gas Extraction
- SIC 14 — Mining & Quarrying of Nonmetallic Minerals, Except Fuels
NAICS Structure Within Mining, Quarrying & Oil & Gas (Linked)
In SIC, mining is divided into four primary groups: metal mining, coal mining, oil and gas extraction, and nonmetallic mineral extraction. NAICS expands these categories within sector 21, separating resource types, drilling operations, mining support services, and quarrying activities. These structures support energy production forecasts, mineral commodity outlooks, geological surveys, land management decisions, and environmental compliance programs across federal, state, and private organizations.
Insights & Research for Mining, Quarrying & Oil & Gas Extraction
Classification data supports forecasting of crude oil, natural gas, and related products across drilling, extraction, and support activities, including shale and unconventional plays.
SIC & NAICS codes distinguish operations producing metals, aggregates, stone, clay, industrial minerals, and construction materials, enabling analysis of commodity demand and regional production patterns.
Support activities—including drilling, exploration, seismic surveys, blasting, and remediation—use classification for regulatory alignment, contractor management, and safety benchmarking.
Classification frameworks support permitting, environmental impact assessments, reclamation planning, conservation programs, and ESG reporting tied to specific resource types and extraction methods.
How These Classifications Are Used
Mining, Quarrying & Oil and Gas SIC and NAICS codes are used by resource companies, regulators, environmental agencies, insurers, investors, and analysts to categorize extraction activities. They underpin exploration studies, regulatory filings, capital planning, commodity forecasting, infrastructure planning, and ESG and safety reporting. Accurate classification ensures resource operations are correctly aligned with safety requirements, production metrics, reserve estimates, environmental compliance frameworks, and supply chain models.
