Iron ore focused investor Red Rock Resources said its 25.2% owned associate Jupiter Mines has set an exploration target of 1.1 billion to 1.3 billion tones for magnetite at the Mt Ida prospect at the Yilgarn Iron project in Western Australia grading from 30% to 40% iron.

The target which was calculated by independent geological consultants Geological Services using 3D modeling, excludes the magnetite potential at the Mt Mason prospect.

However, the exploration target is still conceptual as not enough drilling has been carried out to define a mineral resource and it remains uncertain whether further exploration will result in the determination of a mineral resource.

Under the 2006 agreement with Jupiter, Red Rock is entitled to a 1.5% gross production royalty on all ore production from Mt Ida.

The update follows Red Rock’s subscription to 10 million shares in Canada’s Kansai Mining Corporation to take a 35.2% interest in the company, from which it had previously bought a 15% interest in the Mid Migori Mining Company in Kenya which effectively increased to 44.92% following the transaction and could be upped further to 74.08% if Red Rock completes a bankable feasibility study at the Mid Migori gold project and exercises its option to take a 60% interest in the company.

Jupiter reported high-grade intersections at Mt Ida late last month from a reverse circulation drilling programme, which totalled 2101 metres and returned results including 210m @ 35.0% Fe from surface, 94m @ 29.1% Fe from 124 metres, 72m @ 37.0% Fe from 92 metres, 68m @ 34.1% Fe from 4 metres and 60m @ 32.3% Fe from 22 metres.
