Gold is concentrated within basal conglomerates of the Miclere Basin sitting unconformably on rocks of the Anakie Metamorphic Group. |
|
The basement phyllite and schist below the unconformity commonly also contains some gold. |
|
Gold in the conglomerates ranges from fine to very coarse with the finer gold tending to be irregular and flat or flaky whilst the coarser |
|
gold is commonly rounded. Nuggets to 200g have been recorded and some 'specimen gold' occurs in quartz rich clasts. |
|
Thin flakes on fracture surfaces are developed in places, particularly in the basement schist. Pyrite and siderite are common in the |
|
cementing material within the conglomerate. |
|
The genesis of the mineralisation remains controversal with models ranging from simple deep lead to structurally controlled epigenetic or |
|
unconformity related fluid mixing being proposed. |
