23 June 2008 HIGH-GRADE COPPER INTERCEPTS – KAPULO JV Highlights: • Katanga intercepts – 64.4m @ 5.9% Cu, incl. 40m @ 8.6% Cu, 62m @ 4.0% Cu, incl. 27m @ 8.3% Cu, 100.5m @ 1.0% Cu, incl. 10m @ 5.8% Cu • Safari North intercepts – 27m @ 5.2% Cu, 12m @ 2.7% Australian diversified minerals exploration company Mawson West (ASX: MWE) (“Mawson West” or “the company”) is currently drilling at the Katanga and Safari North copper prospects within the Kapulo Joint venture area with Anvil Mining. The high-grade Kapulo copper deposits are located 130km north-east of Anvil Mining’s operating high-grade copper/silver Dikulushi mine. MWE is the operator and will have earned 65% of the project by August 2008. Drilling Update – Kapulo Project Katanga Drilling has continued to return exceptional results at this prospect with 31 holes completed to date (Figure 1). Latest intercepts are detailed in the table below and can be seen in Figures 2 to 4. Copper grades up to 42.6% over one metre (within a zone of [email protected]% Cu) have been returned from hole 023, which contained massive chalcopyrite and bornite mineralisation similar to several holes yet to be assayed. Hole 023 was terminated in mineralisation due to adverse drilling conditions; hole 023W is a wedge off the parent hole which did penetrate the entire mineralised envelope. Results from the wedge (twin) hole compare very favourably with the parent hole. CORPORATE DETAILS ASX Code: MWE CONTACT DETAILS [email protected] www.mawsonwest.com.au ASX RELEASE Mineralisation remains open along strike and at depth. Results for seven completed holes are still outstanding, and two holes are currently being drilled. Both diamond rigs are currently drilling at the Katanga prospect to speed up drill information which is to be used in the maiden JORC/43-101 resource due in August 2008. Once enough drilling information is available for this interim resource one of the drill rigs will return to Safari North. The maiden JORC/43-101 resource will only include material from the Katanga prospect.
