Lyndon Southern is introducing a new pricing structure tied to a mining-focused liability endorsement as part of an update to its commercial general liability program in Maryland.

The filing centers on a Mining Operations Limited Pollution Liability Endorsement, designed specifically for risks tied to mining activities such as surface and underground operations, ore processing, and drilling. The coverage targets a defined set of general liability classifications commonly used across the mining sector.

Rather than building pricing from scratch, Lyndon Southern is aligning its rates with a prior filing from Imperium Insurance Company.

The filing was submitted on April 20, 2026, and is set to take effect upon regulatory approval.
