Roper River Iron Ore Project EL 28497 South St Vidgeon, First Annual Report for period 31 August 2011 to 30 August 2012

Abstract

Exploration activity completed by Sherwin Iron for the 2011/12 period was largely limited to initial reconnaissance rock chip sampling and mapping. Helicopter reconnaissance was undertaken to sample iron oxide host rock lithologies for their further exploration potential. Reconnaissance of the Munyi Member was carried out over two days in March 2012. Sixteen rock chip samples were collected. The samples were sent to Genalysis/NTEL for analysis for an Iron Ore suite of elements by XRF. Oolitic to pisolitic ironstone was recognized in a few of the samples. In most cases the Munyi Member consisted of ferruginous sandstone which had been laterised to a greater or lesser extent. It was difficult to gain an impression of the thickness of the iron-rich horizon due to the poor outcrop, however it did not appear to be greater than two metres thick. The Munyi Member does not appear in this area to contain economic iron ore mineralization. The full width of the Munyi Member was not exposed in the areas visited and it is possible that more prospective ironstone occurs in the upper parts which did not crop out. The formation should not be written off as a future exploration target. Further low priority sampling should be carried out preferably in areas where the full width of the Munyi Member is exposed.
