1Includes surface drilling in search of new ore deposits or extensions of known deposits and drilling at
the location of a discovery up to the time the company decides sufficient ore reserves are present to justify
commercial exploitation.
Note:    Totals may not equal sum of components due to independent rounding.
2Includes all surface drilling on an ore deposit to determine more precisely size, grade, and
configuration subsequent to the time that commercial exploitation is deemed feasible.
