| History of the Tembang Project |
|
Tembang is an abandoned mine with a recent exploration history dating back to the 1980s.
The historic mine commenced production under a previous operator in late 1997 and ceased production in March 2000 due to a declining gold price. The prior operator mined only the main veins and discarded the lower grade halo mineralisation.

| Geology of the Tembang Project |
|
|
Tembang is a large low-sulphidation epithermal deposit comprising gold-silver bearing quartz sulphide veins hosted by Tertiary volcanics. Two vein styles are present a relatively wide and continuous vein set surrounded by irregular narrower veins that occur in both the footwall and hanging-wall providing a "halo" of mineralisation peripheral to the main veins.
