SECTION 1.0 2020 Annual Reclamation Report

As specified by the revisions (1/3/90) to 2CCR 407-2, 2.04.13, Trapper Mine is submitting an Annual
Reclamation Report for the previous calendar year (2020).

Historically, section 3.5.3 of Trapper's mining and reclamation permit required a reclamation map be
submitted to the CDRMS annually by March 15. Subsequent to 1988 the map entitled the "Postmine
Contour Map" was changed to "Reclamation Map." The reclamation maps developed from aerial
photographs taken during the previous fall shows pit advancements, recontoured spoil areas and a
historical account of the previously regraded areas for the year.

The 2020 reclamation map is a composite of the aerial photographs taken by drone during 2020, and
shows the reclamation performed during 2020 for all areas under bond. Map(s) 1 show the aerial extent
and location of disturbed acres, graded acres, topsoiled acres and perennial seeded acres during 2020.
It also shows the location, aerial extent and reclamation year of all previously revegetated areas, as well
as the actual and projected mature shrub clump establishment areas, topsoil stripping areas and laydown
areas for 2020.
