This property has a documented history as a industrial and manufacturing facility going back to 1982. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Minnie Mine facility in Leecher Canyon operated as a cyanide heap leach processing operation beginning in 1982, when Fred Higby staked mining claims and established a small cyanide leach plant on the property. Cordilleran Development, Inc., as lessees of Higby's claims, subsequently operated the cyanide heap leach operation until mining ceased in 1986. Remediation beginning with an initial cleanup action in 1995 included removal of solids, liquids, and pond liners; excavation, grading, and consolidation of 5,700 cubic yards of ore piles; and capping of contaminated soil with a soil cover. The project concluded with institutional controls including land use restrictions, fence installation, and long-term monitoring through at least 2015, and the site has reached No Further Action status. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
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.
The cyanide contamination at this property originated entirely from heap leach mining operations conducted between 1982 and 1986 — a window during which occurrence-based CGL policies carried no effective pollution exclusion. Both operators with insurable interests during active mining, Fred Higby and Cordilleran Development, Inc., would plausibly have carried Commercial General Liability coverage at the time of the releases. The documented remediation expenditures — ore pile excavation and consolidation, capping, institutional controls, and years of periodic monitoring reviews — represent cleanup costs that historical carriers who issued policies to those operators during the active mining period may still be obligated to recover.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
