Macarthur owns mineral rights for iron ore on two tenements located in the Pilbara region of Western Australia, Strelley Gorge – E45/4735 and Tambourah North – E45/5324. All other mineral rights on the two tenements are held by Macarthur’s spinout company, Infinity Mining Limited (ASX: IMI).
Stelley Gorge Exploration Licence E45/4735 (11.2km2) is located in the Pilbara region of Western Australia and immediately east of Atlas Iron’s Abydos iron ore mine and south of its planned Sandtrax operation which forms part of the Miralga Creek iron ore mine. Reconnaissance rock sampling completed on the ironstone returned several high iron grades (61.3% and 58.11%).
Tambourah North Exploration Licence E45/5324 is located south of Port Hedland and 7.5 km north of Infinity’s Tambourah South lithium project. In 2012, Atlas Iron drilled 26 RC holes in the northern area of the tenement returned significant iron results over the 400m of strike. That drilling recorded significant intercepts in fourteen (14) of the twenty‐six (26) drillholes within goethite and goethitic haematite, including:
- 68m @ 57.85% Fe from 12m (MWRC887)
- 38m @ 56.84% Fe from 0m (MWRC902)
- 36m @ 55.55% Fe from 2m (MWRC886)
- 24m @ 56.85% Fe from 18m (MWRC896)
