Grid in gray is Alaska Coordinate System, zone 1

North-south grid in black is a local surface grid of northings and eastings, in feet,

with origin located at lat 58.0234985°N., long 134.7311267°W.

Northwest-southeast grid is a local grid of cross section (XS) and long section (LS)

coordinates that are used for Greens Creek mine workings. The grid is

rotated 26.5651 degrees counterclockwise from due north

100-foot contours are from 1997 AreoMap computer-drawn map,

with modifications from field surveys

Contour elevations are relative to sea level

Drill hole and underground elevations are relative to Mine system; 

60 feet must be subtracted from these to give elevations 

relative to sea level.

MAP ERRORS

During the 1997 field season, mapping was carried out north of 15000N using a 1 in. = 200 ft 

topographic base provided by Noranda Inc., to which mine coordinates had been added. Many of 

the mapped outcrops were tied to new survey points in 1998. All mapping north of 16950N and 

west of 22100E, including mapping carried out in 1998 and 1999, is plotted relative to survey 

points, claim corners, and drill holes. This information should be accurately located to within a few 

feet. Most mapping between 15500N and 16600N and between 22100E and 24500E was plotted 

relative to topographic features and streams as they appeared on the 1 in. = 200 ft topographic base. 

The topographic features appear to be accurately positioned on the map relative to the mine grid, 

but some claim corners and drill holes were found to be misplotted by up to 90 to 100 ft. It is hoped 

that the geology in this area is plotted reasonably accurately, but outcrop locations should be 

verified relative to new survey points in this area. The area in Big Sore Creek between 16950N and 

16700N, which includes two outcrops, has been stretched about 90 feet in a north-south direction to 

accommodate the difference between the two areas. Areas in Big Sore Basin that were mapped in 

1999 (14300 to 15500N, 21400 to 23000E) were located by reference to the grid that was surveyed 

in this area by David Wilson in 1998 using GPS (not shown on this map). Outcrops in this section 

of the map should be accurately positioned to within a few feet. Most of the area was mapped using 

claim corners as reference points. The coordinates that are available for some claim corners 

disagree with other data, such as drill site locations, suggesting discrepancies of up to 35 ft.

Outcrops mapped in the High Sore area during the 1997 field season were located by reference 

to the High Sore grid. These were plotted on the map using the mine coordinates assigned to the 

brass cap located at High Sore. If future surveying leads to revision of the brass cap coordinates, 

then the High Sore outcrops will merit replotting.

Outcrops mapped in 1997 south of 15000N were located on color air photos at a nominal scale 

of 1 in. = 1,000 ft. The positions of these outcrops are subject to considerable uncertainty. Outcrops 

located east of 21200E and between 13800N and 14200N were plotted using reference points 

surveyed by compass and tape in 1998 by Paul Lindberg. Outcrops in Upper Meadow of Gallagher 

Creek were relocated in 2000 by reference to the GPS-located Upper Gallagher grid. All other 

outcrops in the Upper Gallagher Creek area were mapped by reference to this same grid.
