⚡ Cost Scenarios
📊 Baseline (baseline) $680K/yr
92.5% probability / year
Normal year with no major incidents; routine security, monitoring, testing, and administrative costs only.

🚨 Minor Incident $880K/yr
5.0% probability / year +$200K vs baseline
Localized leak, minor contamination event, or small breach requiring emergency mobilization and remediation.

🚨 Exploration Authorized $1.9M/yr
2.0% probability / year +$1.2M vs baseline
Authorization to instrument or explore the interior chamber (robotics/deep-bore campaign) with large one-time equipment spend and increased research activity.

🚨 Catastrophic Remediation $58.7M/yr
0.5% probability / year +$58.0M vs baseline
Policy decision or catastrophic event forces full infill/remediation of the 1 km chamber with major engineering and environmental mitigation.

📋 Confidence Notes
Analyst notes provide detailed line-item ranges for most costs, giving reasonable precision for ongoing operations; however large optional/contingency items and wide ranges on property/legal and large-scale remediation introduce material uncertainty.
