For all its success, 1996 was a transitional year on the Carlin Trend. Surface deposits
of the easier to process oxide ores are being depleted and, increasingly, new
production is coming from complex refractory ores that require pretreatment before the
gold can be recovered.

Newmont's Carlin operation has become as complex as its ores.

Sophisticated computer modeling, a robotics laboratory that
assays two million ore samples a year and increasing use of stockpiles to segregate ore
by grade, sulfur and carbon content are necessary to optimize operations.

five million tons were stockpiled for future processing.

The refractory ore treatment plant, or Mill No. 6, the largest facility of its type, is pivotal
to Newmont's future.

To the north of the Post deposit, drilling in the Goldbug area doubled the mineralized
material not yet in reserves to 5.7 million tons of mineralization at a grade of 0.288
ounce per ton, and increased the inferred resource base to several times that amount.
This inferred resource consists mostly of low-grade refractory material for which
economical metallurgical recovery methods are being tested.
