The results of this new research has identified a prominent vertical low-resistivity feature (a 'spout') rising to the surface, comparable with that seen beneath the Olympic Dam orebody. HAV has named it the Jupiter MT anomaly. Notably, this feature corresponds closely with a regional aeromagnetic anomaly.
This vertical feature at Olympic Dam has been interpreted as a possible feeder zone for metalliferous fluids from a more conductive and potentially copper rich part of the deep crust in this region.
While highly speculative, the significance of the Jupiter MT anomaly needs to be understood by HAV shareholders.
MT experts are genuinely excited by the remarkable analogy to the distinctive Olympic Dam signature. See the University of Adelaide paper (below) published December 2017:
The really important part of the above, the Jupiter MT anomaly is across Havilah's mineral tenements. In addition, to the immediate east of the Jupiter MT anomaly Havilah Management was able to acquire the mineral tenements it did not already hold.
To date, HAV has executed a number of Jupiter MT confidentiality agreements with the 'majors'. The aim being to secure a JV partner to investigate (and expend exploration dollars across) the Jupiter MT anomaly during calendar year 2018.
As a result of the above, I did some research over the last few weeks re: older papers on MT over the Curnamona Province, for those that are interested.
Magnetotellurics: Curnamona Province
In its ability to retain signatures of tectonic events that enrich or deplete its fertilization state, the lithosphere holds the key to the tectonic evolution and history of Earth.
MT is a passive geophysical tool that images the physical property of electrical resistivity and is capable of penetrating the entire lithosphere.
MT is a passive geophysical tool that images the physical property of electrical resistivity and is capable of penetrating the entire lithosphere.
MT is highly sensitive to minor interconnected conducting mineralogy and fluids, and thus is ideal for distinguishing between lithosphere of different degrees of enrichment. Additionally, the sensitivity to these minor phases means that fossil fluid pathways associated with the ascent of mineralising fluids and metals are detectable with MT.
This is the cornerstone on which one of the main directions of the UNCOVER (Australian Academy of Science, 2012) initiative is based on-increasing the detectable signature of ore deposits by imaging the underlying fluid pathways and lateral dispersion of deposits.
The Curnamona Province is a large, near-circular area of Palaeoproterozoic to Mesoproterozoic rocks in the northeast of South Australia and west of New South Wales.
The Benagerie Volcanic Suite share geochronological, geochemical, and isotopic affinities with the upper Gawler Range Volcanics of the Gawler Craton indicating these two volcanics suites can be considered part of a formerly contiguous Mesoproterozoic silicic large igneous province.
A total of 74 long-period magnetotelluric (MT) stations were deployed across the Ikara-Flinders Ranges and the adjacent Curnamona Province as a part of the Australian Lithospheric Architecture Magnetotelluric Project.
The large Curnamona Conductor within the Curnamona Province occurs at depths of 5–40 km in a region that is thought to have been unaffected by tectonic events since the Olarian Orogeny (1.6 Ga), with the exception of the Delamerian Orogeny in the Cambrian which has modified only the edges of the province.
A particular objective was the imaging of the deeper crust and major structural features that may have influenced hydrothermal fluid flow and hence mineralisation. The complexity of the work requires collaboration and does not just rely on the expertise of seismic interpreters. The results show a crustal architecture for the CurnamonaProvince of eastern South Australia that provides important information on basement architecture that will enhance investment and targeting strategies for mineral explorers in the province.
One example is the observation that the Kalkaroo prospect appears to be related to second order faults associated with hanging wall anticlines above a major bounding east-dipping fault at depth, opens up the possibility for further mineral deposits associated with other hanging wall anticlines above east-dipping faults.
