ASX Announcement ASX Code: MMX, MMXO 11 May 2007 JACK HILLS IRON ORE PROJECT * DRILLING RESULTS
Murchison Metals Ltd is progressing with a drilling programme to define the extent of mineralisation for Stage 2 of the Jack Hills Project. The drilling programme is designed to target extensions to mineralisation below and along strike of the Stage 1 Reserve. The drilling programme continues to intersect wide, high grade lenses of massive iron ore.
The results reported are predominantly strike extension and depth extension drilling. Zones of high grade iron ore mineralisation have been intersected below areas of little or no iron ore outcrop and adjacent to known ore lenses. Drill holes MHRC272 & 273 fall into this category. After all of the data has been received and analysed, it is expected that follow up holes will be required to identify the full extent of this new zone. The intersections reported confirm the continuity of mineralisation and the potential of the project to host large tonnages of high grade mineralisation. Drilling has commenced on the Brindal lens and a second special purpose RC rig will be mobilised to site this week to assist with the drilling programme. The results from drill holes 170 to 289 (120 holes) have been finalised and are tabulated below. These results represent a further 24,565m of drilling. The results of eight drill holes (2,288m indicated in the table) are currently unavailable. As reported on 10 April 2007, within the deeper zones of the H4 lens, carbonate veining and cavity filling associated with the iron mineralisation has been identified. Murchison is completing a metallurgical testwork
programme designed to remove this material.
