Host minerals for gold have
been of great interest to exploration
geologists and metallurgists for a
variety of reasons. The depletion of
high grade ores in many parts of the
world requires that greater attention
be given to the study of host min-
erals for gold. Some host minerals
have been employed in exploration as
traces for gold. They are also
essential in the design of extraction
processes for treating gold ores.
This paper reviews the
mineralogy of important gold deposits
of Papua New Guinea (PNG), Indonesia
and New Zealand and focuses attention
on the ore minerals and rock-forming
minerals that host gold.
