Why no per-state rates here? Colorado is an NCCI state where loss-cost data is published only to NCCI subscribers, not in public state insurance department filings. The class codes above use the same NCCI nomenclature, but your binding rate comes from your carrier's filed loss cost multiplier (LCM) applied to those base loss costs.

Filing checklist for Mining & Extraction businesses in Colorado

  1. Step 1, Confirm coverage threshold

    All businesses with employees, regardless of number of employees, part-time status, or family relation. For Mining & Extraction operations, this typically applies once you make a first W-2 hire, even part-time.

  2. Step 2, Pick the right class code

    Mining & Extraction businesses typically use codes like 1624, 1164, 1165. The wrong code can cost 4 to 10x more or get reclassified at audit. Across reporting states, Mining & Extraction median rates run $1.66 per $100 with a range of $0.190 to $43.34.

  3. Step 3, Get a quote

    Pinnacol Assurance is one option in Colorado; private carriers (Travelers, Hartford, Liberty Mutual, AmTrust) also write coverage. Schedule credits up to 25% are typical for low-loss accounts.

  4. Step 4, Document subcontractors

    A principal contractor is generally liable for injuries to employees of uninsured subcontractors. Mining & Extraction operators with crews of 1099s should keep certificates of insurance for every sub, otherwise the GC absorbs the sub liability at audit.

  5. Step 5, Annual audit

    Carriers audit payroll within 90 days of policy expiration. Have payroll segregated by class code, job descriptions on file, and overtime properly excluded from rated payroll. Mining & Extraction class allocation can shift if any worker spends more than 50% of time on a different code.

Penalty for non-coverage in Colorado: Failure to carry workers' compensation insurance can result in fines, stop-work orders, and personal liability for employee injuries.
