Why a Lender Would Protect a Mining Claim
Unpatented mining claims on federal land require annual maintenance. Either the claim holder performs assessment work or pays the required fees to the Bureau of Land Management. Miss a year, and the claim can be forfeited. If a mining claim secures a mortgage, forfeiture would wipe out the lender's collateral entirely.
The mortgagee, if the mortgaged property or part thereof consists of unpatented mining claims, may perform the annual labor or improvement, or pay the maintenance fees required by law to prevent the forfeiture of the claim, and the amount expended for that purpose shall be an additional debt secured by the mortgage, and included in the judgment of foreclosure.
A.R.S. § 33-704This statute gives the lender a practical tool. If the borrower neglects the claim, the lender can step in, cover the costs, and add those expenses to the secured debt. The added amount gets included in any foreclosure judgment or, if spent after judgment but before sale, added to the execution amount.
A Narrow but Important Protection
This provision applies specifically to unpatented mining claims, not to residential or commercial real estate. Arizona's mining heritage means these situations still arise, particularly in rural parts of the state where mineral rights carry real value. For families with mining interests as part of their estate, understanding how mortgages interact with claim maintenance is important for succession planning.
