Murtoa Project

Aircore Drilling – Murtoa


Rimfire Australia Pty Ltd

A subsidiary of Kiska Metals Corporation (TSX.V code: KSK)


North of Horsham in west Victoria


Leviathan Pty Ltd

(Wholly owned subsidiary of Crocodile Gold Corp)

In joint venture with Kiska Metals Corp., operated by Rimfire Australia

Regional Geological Setting:

The Project area stratigraphy consists of accumulations of basaltic rock draped in ferruginous (iron-rich) volcanogenic sediments overlain by pelitic schists (shales).  This stratigraphic arrangement is considered to represent a failed VMS type setting developed at isolated basalt centres.  Subsequent deformation along crustal scale structures resulted in orogenic mineralisation.

Target Metals:


Mineralisation setting:

Similar to that being mined at Stawell.

Orogenic gold mineralisation at the Stawell mine is dated at 440 Ma and consists of gold bearing quartz vein systems that occur largely within the volcanogenic sediments that wrap around the western flank of the large, doubly plunging Magdala basalt antiform.  Gold accumulation is thought to be developed where these dilational zones and fluids interact with the ferruginous sediments.

Target size:

+100,000 oz. gold in altered, sulphidic meta-sediments

Exploration History:

Extensive database of deep AirCore, RC and diamond drilling near Wallup.

Gravity, CSAMT, AMT and soil geochemistry surveys

Exploration Tools:

AirCore drilling

Significant Outcomes:

AirCore drilling in May 2012 successfully sampled basement lithologies.

Results still in interpretation phase.


Similar in size to that at the Stawell Gold Mine


Rimfire (Kiska) withdrew from the JV, tenement relinquished by Leviathan in 2014.
