The department shall require as a prerequisite to the issuing of any lease a rental as set by the board but not less than one dollar and twenty-five cents per acre or such prorated share of the rental per acre as the state's mineral rights ownership for the first year of such lease, payable in advance to the department at the time the lease is awarded and a like rental annually in advance thereafter so long as such lease remains in force. However, the rental shall cease at such time as royalty accrues to the state from production from such lease. Commencing with the lease year beginning on or after oil, gas, or other hydrocarbon substances are first produced in quantities deemed paying quantities by lessee on the land subject to such lease, lessee shall pay a minimum royalty as set by the board but not less than five dollars per acre or fraction thereof or such prorated share of the rental per acre as the state's mineral rights ownership at the expiration of each year. Royalties payable by the lessee shall be the royalties from production as provided for in RCW
79.14.070 or the minimum royalty provided herein, whichever is greater. However, if such a lease is unitized, the minimum royalty shall be payable only on the leased acreage after production is obtained in such paying quantities from such lease.
