Edie Creek Mine (PNG)

Niuminco Ltd:


8 km west of Wau in the Morobe Goldfield of Papua New Guinea

Regional Geological Setting:

Late Tertiary porphyry intrusives within Cretaceous metamorphic (volcaniclastics) sediments.  Regional south directed thrusting provided numerous structural preparation for the later influx of hydrothermal fluids.

Target Metals:

Gold, Silver

Mineralisation setting:

Low sulphidation carbonate epithermal gold-silver mineralisation.  Hydrothermal fluids deposited gold-silver mineralisation associated  with pyrite-clay-sericite alteration of host porphyry and metasediments.  Many structural settings associated with different phases of the thrust event give rise to different ore zones each with own characteristics

Target size:

2 to 5 million ounces contained gold

Exploration History:

Discovered in 1926, with bonanza grades worked in alluvials leading to gold rush (both on ground and Australian Stock Exchange activity).  Minor underground mining ceased in 1942 (WWII), with only small scale alluvial and primary vein mining since 1945.

Exploration Tools:

Trench mapping and sampling, face mapping and sampling, regional mapping and 3D geological modelling, structural interpretation, modelling of underground workings.

Diamond drilling

Significant Outcomes:

Recognition of major and secondary structural controls to mineralisation,

Recognition of sulphide potential,

Geological modelling & interpretations  added value to the Project, leading to successful JV negotiations


Has potential to be a major gold producer in this well endowed goldfield in eastern PNG.  Its proximity to the Hidden Valley / Hamata gold mines, and the historic Wau gold mines underscores its unlocked potential


Currently in JV with Mincor Resources NL.  EMS no longer involved.
