The program is targeting the unusual anomaly at Behemoth for nickel, copper, gold and rare earths.
Rings of magnetic material buried beneath the desert have formed a 12-kilometre diameter unexplained magnetic ring feature that is only visible through airborne magnetic surveys.

First drilling in region
No previous drilling for potential sulphide mineralisation at depth has been undertaken in the region, although surface sampling for diamond exploration in the 1980s revealed anomalous gold in geochemical soil samples at surface.
Two deep diamond drill holes are each being drilled to an approximate depth of 550 metres with funding assistance from the WA Government Exploration Incentive Scheme.
The holes are targeting the results of gravity and IP geophysical surveys conducted by SOR that discovered large-scale anomalous zones.
These zones are open and well within modern drilling depths.

Both holes are vertical with about 150 metres of reverse circulation drilling and 400 metres of diamond drilling to an approximate total depth each of 550 metres.
Drilling is expected to take several weeks depending on water, logistics and sub-surface conditions.
Assays will then be sent for geochemical analysis.
Deep hole directional drill specialists
This work is being carried out by DDH1 Drilling, one of Australia’s leading mineral drilling contractors specialising in deep hole directional drilling services.
DDH1 has been involved with some of WA’s richest mineral discoveries including the recent highly successful Greatland Gold PLC (LON:GGP) Havieron project, Sandfire Resources NL (ASX:SFR) Degrussa copper-gold mine and the Nova Nickel-Copper project now owned by Independence Group NL (ASX:IGO).
This company has enhanced the Behemoth drill program team with the engagement of OMNI GEOX to manage the program.
Possible meteorite feature
Experts are divided on whether the large buried multi-ringed magnetic feature at Behemoth is caused by the impact of a meteorite from above, an intrusion of magma from below and/or an associated mineral system.
Recent IP geophysical surveys identified multiple large potential zones of buried sulphides within the magnetic rings feature.
Multi-ringed meteorite impact structures are well recognised overseas to be associated with significant mineral resources.
The Witwatersrand Basin, which has produced about 40% of all gold mined on Earth and the world-class nickel-copper-PGE sulphide deposits in mafic ultramafic intrusions of the large Sudbury impact structure are well-known examples.
However, there are numerous other deposits (Carswell uranium, Ternovka iron ore-uranium etc) that are linked with impact structures.
The Behemoth project is part of a frontier exploration effort by SOR in unexplored Western Australian deserts.
There are only a handful of mineral exploration drill holes in around 100,000 square kilometres area of desert around the planned Behemoth drill holes.
Most investors in SOR pay no tax on capital gains from selling their SOR shares as the company operates under a Federal Government program set up to encourage investment into innovation.
