Squence number is a unique 10-digit number.

Name of deposit or operation is the primary or most common name.

The product name.

Type of operation.  Refers to the existing/proposed type of operation at this site from the table below.  It identifies the existing operation when rent status equals PRODUCER, PAST PRODUCER, TEMP SHUTDOWN or DEVEL DEPOSIT.  It identifies the proposed operation when DEPOSIT.  It identifies the proposed operation when current status equals EXP PROSPECT or RAW PROSPECT.  All processing plants will be coded 'PROC PLANT' here and further defined with the PLant Type(PLT) and Plant IDentifier (PID) fields.

Current status

LATitude is a seven-character field with four subfields.  Direction (either N or S) must be entered in field position1.  Field positions 2 and 3 are degrees (maximum value is 90).  Field position 4 and 5 are minutes (maxiumum value is 59).  Field positions 6 and 7 are seconds (maxiumu value is 59).

Latitude in decimal degrees

Longitude is an eight-character field consisting of four subfields.  Direction (either E or W) must be entered in field position 1.  Field positions 2-4 are degrees (maximum value is 180).  Field positions 5 and 6 are minutes (maximum value is 59).  Field positions 7 and 8 are seconds (maximum value is 59).

Longitude in decimal degrees.

Point Of Reference, indicates the physical determination point for the elevation, latitude and longitude data, as selected from the table that follows.

Precision Of Point gives the precision or maximum deviation from exact POR in meters.  POP is a required if POR is entered.  An entry of 99999 indicates that the precision is over 10000 meters.

UTM Zone number

In the northern hemisphere, this represents the distance in meters north of the equator; the equator is 0 meters with numbers increasing northward.  In the souther hemisphere, it represents the distance in meters north from about 80 degrees south latitude; the equator is 10 million meters, with numbers decreasing southward.

Represents the distance in meters from a central meridian in each UTM zone.  The central meridian is givien an arbitrary value of 500,000 meters.  Measurements increase to the east and decrease to the west of the central meridian, and are terminated by the respective east and west boundaries of each of the 60 zones.

Identifies the U.S. Geological Survey 1:250,000 series map on twhich the deposit can be located.

Entry of the name of the largest-scale map available for the area of the desposit.  If the name is larger than 17 characters it should be shortened to a recognizable name.

Contains the name of the Principal Meridian.

Second portion of latitude

The township number.  The first three characters are the township number with leading zeros, the fourth character is either blank or contains a plus sign (+) to indicate a fractional township, and the fifth character locates the township north (N) or south (S) of the base line (e.g., T32 N is entered as "032 N" , and T 104-1/2 S is "104+S")

Includes the range number and direction, using the same conventions outlined in TOWNSHIP.  Except that the directions use for ranges are either east (E) or west (W) of the base line.

The section number.
