GOLD AND BASE METALS
Winnecke – Sliding Rock Well Project
This project area comprises two adjacent tenements,
EL23630 and EL25469, located on the Arunta Block –
Amadeus Basin unconformity. Winnecke EL23630
encompasses the historical workings of the Winnecke
Goldfield, with a recorded production of 12,000 oz gold.
The area has been the subject of much work by previous
explorers, but this is the first time a systematic approach
using high resolution geophysics on a tenement scale
has been applied.
Sliding Rock Well EL 25469 was secured to investigate
an isolated high intensity magnetic anomaly with
possible copper-gold affinities.
During the past 12 months exploration activities
have included:
• Acquisition of high resolution magnetics and
radiometrics data on 100 metre flight lines.
• Acquisition of detailed airborne EM data
(“SkyTEM”) on 150 metre flight lines.
• Interpretation of all datasets to define priority
targets for drilling.
• Acquisition of ground magnetic data and drill-site
definition at Sliding Rock Well.
The interpretation of the EM, magnetic and radiometric
data has resulted in identification of three priority 1
and four priority 2 targets. The priority 1 targets are
conductors with time constants of 0.7 to 4.8, which is
consistent with anomalous accumulations of sulphides.
These may be sulphides of copper or lead, or possibly
iron sulphides with associated gold mineralisation.
The Sliding Rock Well aeromagnetic anomaly is an
isolated 2,500 nT response in greenschist facies schist
with some mylonite and breccia. Similar magnetic
anomalies are observed over the Johnnies Reward
copper-gold mineralisation 14 kms to the north, and
over the Molyhil molybdenum-tungsten deposit further
to the northeast.
