1. THE EXISTING CONDITIONS WITHIN AND IMMEDIATELY ADJACENT TO THE SOUTH OPEN CUT (PIT LAKE, HAULAGE WAY, DRY

CREVASSE, JEEP TRAIL) AND SOUTH MINE DEPICTED ON THE DRAWINGS ARE BASED UPON AN AERIAL SURVEY CONDUCTED

ON APRIL 9, 2012, CONDUCTED BY AERIAL SURVEY AND PHOTO, INC. OF NORRIDGEWOCK, MAINE. HORIZONTAL DATUM:

VERMONT STATE PLANE COORDINATES, NAO 83, (CORS96) US FEET. VERTICAL DATUM: NAVO 1988.

2. SIGNIFICANT SHADOWS AT ROCK FACES ALONG THE SOUTH OPEN CUT PIT LAKE AREA WILL RESULT IN INACCURACIES

WITHIN THE AERIAL TOPOGRAPHY AS MAPPED FOR THOSE AREAS.

3. GROUND CONTROL AND ADDITIONAL GROUND SURVEY TO SUPPLEMENT THE AERIAL SURVEY CONDUCTED IN APRIL AND

MAY 2013 BY AMEC ENVIRONMENT AND INFRASTRUCTURE OF PORTLAND, MAINE. HORIZONTAL AND VERTICAL CONTROL

WAS ESTABLISHED UTILIZING SURVEY GRADE GPS OBSERVATIONS (2 HOUR MIN) WITH NGS-OPUS SOLUTIONS. SEE

DRAWING C-100 FOR HORIZONTAL AND VERTICAL CONTROL POINT LOCATIONS AND DESCRIPTIONS.

4. EXISTING CONDITIONS IN THE VICINITY OF TP-1, TP-2, AND THE EAST SIDE DIVERSION CHANNEL (COPPERAS BROOK) ARE

BASED UPON VARIOUS HISTORIC SURVEYS AND AS BUil T CONDITIONS PROVIDED BY NOBIS.
