Development Requirement

The operations contemplated in each lease shall be carried on with due diligence and in a workmanlike manner. Lessees will conduct such examinations, explorations, testing, and samplings as may, in competent judgment, be necessary to determine the extent, quality, feasibility, and economic potential of the mineral resource in, upon, and under the leased premises, together with such other studies as may be necessary for it to reach a determination as to development methods, preparations, equipment, and mining of the leased premises. The lessee shall expend for approved development work within the times and in the amounts as follows:

(1)

According to the total number of acres covered by advance rental payment each year under this lease, prior to the end of the first year of each mineral lease — an amount equal to the total number of acres leased in each lease multiplied by $1; and

(2)

Prior to the end of second year of each mineral lease — an additional amount equal to the total number of acres in possession under each lease at the beginning of the second year multiplied by $2; and

(3)

Prior to the end of each subsequent year of each mineral lease — an additional amount annually equal to the total number of acres in possession under each lease at the year’s beginning multiplied by $3.

(4)

Development work or improvements, to be acceptable, must contribute directly to the mining or mineral potential of the property.
