43 CFR 3251.14 - Do I need a bond for conducting exploration operations?
(a) You must not start any exploration operations on BLM-managed lands until we approve your bond. You may meet the requirement for an exploration bond in two ways:
(1) If you have an existing nationwide or statewide oil and gas exploration bond, provide a rider in an amount we have specified to include geothermal resources exploration operations; or
(2) If you must file a new bond for geothermal exploration, the minimum amounts are:
(i) $5,000 for a single operation;
(ii) $25,000 for all of your operations within a state; and
(iii) $50,000 for all of your operations on public lands nationwide.
(b) See subparts 3214 and 3215 for additional details on bonding procedures.
