The Tom Thumb Mine operated as a gold and silver mine in Republic, Ferry County, from 1908 to 1938, with ore shipments documented in 1908–1910, 1915, 1916, 1934, and 1938. The site includes multiple mine shafts and waste rock piles; closure activities have included the filling of Shaft 3 by Hecla Mining Co. and the closure of Shafts 1, 2, and 4. The mine is inactive, and the site is currently awaiting cleanup under the Standard Cleanup program. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
Mining operations at this site began nearly eight decades before 1986, placing the entire operational history squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Metals contamination associated with decades of waste rock accumulation is the type of gradual, operations-linked release those policies were written to cover. The cleanup costs the property now faces — investigation, design, and remediation of legacy mine workings and waste rock — could plausibly be funded by historical carriers whose policies were in effect during the mine's active years.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
