COMMENTS

This was an aerial inspection of the New Horizon North Mine conducted by Harry Ranney and Brock Bowles of
the Colorado Division of Reclamation, Mining and Safety. Aerial photos were taken on December 1, 2016 at
approximately 12:00 pm. Brock Bowles reviewed the aerial photos. The weather conditions appear to be clear in
the photos as objects on the ground projected shadows. There was a light dusting of snow on the ground.
AIR RESOURCE PROTECTION – Rule 4.17:
The coal stockpile is in place by the east haul road entrance (photo 1). With white snow on the ground,
there does not appear to be fugitive coal dust on surrounding areas at the time of the photos.

The water truck was parked under the water tank, presumably being filled for dust control.

HYDROLOGIC BALANCE - Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, 4.05.10;
Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13;
Drainage – Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
Pond 001 contained water. The east and west ditches appear to be in good condition.

Pond 002 contained a small amount of water in the north end of the pond. It does not appear the pond was
discharging due to the small amount of water. The north and south ditches appear to be in good condition.

GENERAL MINE PLAN COMPLIANCE:
Overburden is being transported by haul trucks from the lower west part of the pit to the upper east side
and is being spread with a bulldozer.

The highwall has been reduced in length. The ends of the highwall have moved further away from the 2600 Road
on the west end and the 2650 Road on the east end(photo 3). The drill rig is drilling holes in the middle of the
mining area.

ROADS – Rule 4.03
Construction 4.03.1(3)/4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance 4.03.1(5) and
(6)/4.03.2(5) and (6); Reclamation 4.03.1(7)/4.03.2(7):
The haul road and access road appear to be clear and well maintained.
