Mt Wellington Project (Victoria)

Under Mt Wellington Gold Ltd:

Location:

80 km north-east of Melbourne, Victoria
Between the Ski Fields of Mt Baw Baw and Mt Buller

Regional Geological setting:

Intermediate Cambrian volcanics and associated sediments (Licola Volcanics) beneath overthrust Silurian quartzites and meta-siltstones.

Target Metals:

Gold, Copper and Zinc

Mineralisation setting:

Initially considered to be VHMS setting, but mineralogical and isotope studies led to conclusion of a high level, magmatic related epithermal Cu-Au (± pyrrhotite) style.

Target size:

Medium to significant tonnage of low grade copper and gold deposits

Exploration History:

Rhyolite Creek (epithermal gold) discovered by BHP minerals in 1986

Exploration Tools:

Geological mapping
Airborne radar imagery (AIRSAR) data collection & interpretation
Induced Polarisation
Fixed & moving loop EM
Ground magnetic surveys
CSAMT
Soil geochemistry (4000 samples) and alteration mineralogy (soil PIMA)
Block modelling of soil & drill PIMA data
Rock geochemistry (3700 samples)
MMI and Deep Leach soil geochemistry
RC (10,200 metres in 98 holes)
Diamond drilling (2,300 metres in 9 holes)

Significant Outcomes:

Hill 800                   1994 (epithermal Cu-Au)
Long Ridge              1994 (epithermal Cu-Au)
N16                         1995 (carbonate zinc + copper)
Violet Hill                 1995 (lead-zinc in VHMS setting)

Potential:

Significant potential to develop known geochemical anomalies, and for further discoveries in these prospective volcanics.

Under Goldsearch Ltd:

Location:

80 km east of Melbourne in the Alpine region of Victoria

Regional Geological setting:

Intermediate to felsic Cambrian volcanics and associated sediments (Jamieson and Licola Volcanics) beneath overthrust Silurian quartzites and meta-siltstones.
 

Target Metals:

Gold, Copper and Zinc

Mineralisation setting:

Magmatic related, low sulphidation epithermal Zn-Cu-Au style. Permeable-impermeable lithological boundaries act as structural traps to rising hydrothermal fluids

Target size:

Medium to significant tonnage of low grade copper and gold deposits, and high grade zinc-gold deposits

Exploration History:

Rhyolite Creek (epithermal gold) discovered by BHP minerals in 1986, Hill 800, Mikes Bluff, Log Ridge Prospects discovered by Mt Wellington Gold in 1994 – 1995

Exploration Tools:

Geological mapping with 3D modelling
Diamond drilling at Rhyolite Creek, Long Ridge and Mikes Bluff

Significant Outcomes:

Rhyolite Creek – 5.6metre intersection from 220 metres returned an average gold grade of 2.19 g/t with a peak one metre interval of 8.95 g/t gold. This interval also returned individual sample intervals of up to 127 g/t silver, 17.9% zinc, 1.5% lead and 0.8% copper. A 60 metre zone from 220 to 280 metres averages 1.1% zinc – See Open File Reports on Exploration Licences 4835 and 4976 and predecessors.

Potential:

Drilling at Rhyolite Creek proved the association between magnetic anomalies and mineralisation. At least five significant aeromagnetic features remain to be tested in these prospective volcanics.

Status:

Exploration resuming:

Goldsearch Ltd surrendered all tenements by 2014.  Hill 800 and Rhyolite Creek prospects currently held by Jamieson Minerals Pty Ltd under EL5523.

Long Ridge, Whisky Knob, Mikes Bluff and Violet Hill prospects now controlled by Castalian Exploration Pty Ltd under Exploration Licence Application EL5541.
