Outline
The Spinifex Ridge East Project covers greenstone lithologies which are host to a number of commodities including, molybdenum, copper, gold, nickel, chromium and iron.
Appreciable amounts of gold and molybdenum have been located about 1km outside and along strike of the project area. The Spinifex Ridge Molybdenum-copper deposit is considered to be one of the largest undeveloped molybdenum deposits in the world.
The project area covers about 13 km of a granodiorite/greenstone contact. It is close to this contact where, at Coppin Gap, molybdenum mineralisation has been found hosted by offshoots, or dykes of the granodiorite. For this reason, the entire contact is highly prospective for similar style of mineralization.
The identification of several gossanous copper-rich alteration zones very close to a large copper-molybdenum mineralised system is considered to be highly encouraging.
Geochemical work in the form of rock chip and soil sampling has so far identified four surface copper finds immediately east of the Spinifex Ridge Molybdenum Project: Copper Gossan, Terry’s Gossan, Copper Find and Norm’s Find (see Fig. 1 slide 12). Copper is a good pathfinder element for molybdenum and all copper occurrences were anomalous in molybdenum and several other elements such as gold and silver. Furthermore, gold anomalism within the tenement has also been identified.
Recommendations
The potential of high grade iron occurrences in the Coppin Gap area should be further investigated in view of the encouraging drilling results and current mining by Moly Mines on the same lithological contact that trends into the tenement.
Several gold enhanced areas over lithological and structurally identical geology should be further investigated for the presence of Bamboo Creek style gold mineralisation.
It is recommended that follow-up work over all geochemically anomalous areas in the northernmost area of E45/2596 should include:
- Follow-up infill soil and rock sampling and also detailed geological and structural mapping to further detail the anomalies.
- Carry out initial ground geochemistry to assess the iron ore potential at Coppin Gap.
- Conduct ground EM geophysics for better target definition over the most promising areas.
- Test RC drilling of the better targets
Other activities to be considered include the flying of detailed low level aeromagnetics, acquiring aerial photography and satellite imagery, a detailed structural analysis, detailed mapping and further sampling along the entire greenstones-granitoid contact within the licence.
