The material eroded from the mine site and erodible waste dumps feeds particles of gold into the Porgera River that small scale miners none of whom are employed by PJV extract by panning. The small scale miners then add liquid mercury to amalgamate gold into a concentrate. It seems inevitable that some mercury is spilled into the river.

In many mines throughout the world, waste rock and tailings are disposed of separately to form waste dumps and tailings dams. At Waihi the situation is unusual, in that waste rock is used to form engineered embankments that are progressively raised in order to keep up with tailings production. This allows for sufficient storage capacity to ensure that the water within the tailings pond
The deposition of gold mine residues has left the country, Gold plant tailings at present amount to a little over 100 million tons per year and this figure is expected to increase in the future. The tendency is to mine lower grades, which will result in lower gold values in residues. A new development in the industry is the classification of the residue by cycloning and the use of the

The group expects gold production for this year to be revised down to about 176,000oz, only 5 lower than the previous guided production of 185,000oz. The impact from restrictions was mitigated by the group's ability to increase output from surface toll treatment and low grade surface stockpile processing initiatives, in substitution of underground production.
As gold mining is an expensive exercise, opportunities for low cost gold production need to be found, which is spurring the retreatment of tailings,
