Segue resources own the tenement in the strike south of bmy
pardoo area.it has now been farmed to mithril(mth),however
for followers of brumby its the surveys that indicate the
extension that geoff jones spoke of,this area that brumby
have has not been explored..
Highway and Supply Well Project Summary
Segue through its wholly owned subsidiary, Westralian Nickel Ltd, is the owner of the Highway & Supply Well Project which comprises two adjoining exploration licenses covering 174 km2 located on the Great Northern Highway, approximately 100km east-northeast of Port Hedland in the Pilbara region of Western Australia.
The Project, being 15km from the coast, is ideally positioned to benefit from Port Hedland’s significant infrastructure of roads, power, rail and a deep sea port.
Previous drilling of the Project has defined a low-grade JORC compliant inferred resource of 37MT @ 0.3% Ni and 0.12% Cu using a 0.1% Ni lower cut-off.
However, recent reviews and re-sampling of diamond drill core has returned assays as high as 5.85% Ni over 0.32m at Supply Well and 2.11% Ni over 1m at Highway, which indicates higher grade nickel sulphides are present within the Project area.
The principal exploration target for Segue is nickel/copper sulphide mineralisation associated with the regional east-northeasterly trending De Grey Structural Zone (also known as the Pardoo Fault) of which the Project contains 25km of effective strike.
Recent work has included airborne magnetic and radiometric surveys in addition to ground electromagnetic surveys along the historically identified nickel/copper sulphide zones to supplement previous, but less effective surveys. This has resulted in new anomalies, and better definition of earlier anomalies that have only sparsely drilled.
Specifically, fourteen individual conductor anomalies have been delineated of which four have similar characteristics in size and intensity to the Highway mineralised zone with no previous drill testing at all. These anomalies present immediate drilling targets for massive and disseminated sulphides.
In addition to this work, a helicopter VTEM (versatile time-domain electromagnetic) survey has also recently been completed over 174km2 to identify further conductors for ground follow-up.
An outcome of the recently completed aeromagnetic survey is the identification of a circular feature in the northern part of the Highway tenement. Further investigation of open file data reveals that this feature is coincident with a significant gravity anomaly.
Numerous explanations have been proposed to explain this gravity anomaly, however, independent consultants believe the most likely explanation is a layered mafic-ultramafic intrusion. Curiously, the De Grey Structural Zone appears to intersect this feature. Mineralisation associated with the Highway deposit although structurally controlled, appears to be quite an unusual style and does not fit neatly into any conventional model of nickel sulphide occurrence.
Segue intends to test whether this circular gravity anomaly is the source of primary nickel and copper mineralisation and that the structural dislocation has then been responsible for remobilising this mineralisation into the De Grey Structural Zone.
Layered mafic-ultramafic intrusions are not uncommon in Australia and contribute to a small, but significant amount of nickel, copper and platinuim group element (PGE) resources/production. Local examples include Radio Hill (Ni, Cu) and the Munni Munni intrusion (PGE), both near Karratha and Sally Malay (Ni, Cu, Co) in the East Kimberley.
Segue are confident this under-explored region, hidden under sedimentary cover has the potential to host significant resources of nickel, copper and platinum group elements. Segue intends to embark on ground geophysical work to generate more ground EM targets along the De Grey Structural Zone, and ground gravity surveys to highlight potential targets of basal ultramafic accumulations within what is believed to be a layered mafic-ultramafic intrusion. This will be followed by a significant round of drilling after the northern wet season to test the generated targets.
The tenement is also highly prospective for iron ore, undercover containing the northern limb of the Goldsworthy syncline. The Goldsworthy Mine, only 8km from the tenement, last operated in 1982 and produced 157Mt of iron ore over 15 years.

brumby is going through the approvals for these pardoo
tenements & with an extra $2.5m are looking to prove up the
iron ore at pardoo to go with goldsworthy,the tenement that
backs onto one of bhps area in the nimingarra formation i
believe md geoff jones considers just that project alone to
be a very large deposit,the biggest favour is these are
part of a large formation being mined by bhp at yarri &
extend further south to pardoo & have had no exploration as
i could find no previous tenement history on brumbys pardoo
projects as they are all new areas right on the coast,i
watch with interest the MTH drilling at the southern tip of
brumbys pardoo strike.
