. Major Mumbwa exploration programme starting with target verification and over 5,500m of diamond drilling planned to start in May 2006.
. In depth 3D Geophysical Interpretation of FalconTM data highlights high priority drilling targets including a strong uranium anomaly associated with a major north-south structure.
. Drilling will focus initially on the Kitumba region. 8 of 9 holes drilled by BHP Billiton in the mid-late 1990s encountered significant mineralisation (including 60m @ 0.6% copper and 0.11 g/t gold) over a strike length of approximately 6 km, but this tested areas peripheral to the targets indicated by the recently acquired FalconTM data (see Table 1)
. The Mumbwa Project lies within a known mineralised iron oxide copper-gold (IOCG) terrain in west central Zambia covering nearly 5,200 km2 and containing numerous prospects.
. AIM is earning a 70% interest from BHP Billiton and is budgeting to spend US$1.2 million over the next 6 months.
In Depth 3D Geophysical Interpretation of FalconTM Data
AIM Resources (AIM / ASX: AIMR/AIM) has been able to draw on the expertise of BHP Billiton and their proprietary SolidEarthTM software to undertake direct 3D inversion of FalconTM Airborne Gravity Gradiometer data. The result is improved 3D inversion models, which are then analysed using neural network techniques to highlight zones of anomalism in the target earth volume.
It has been demonstrated from BHP Billiton's internal interpretation work carried out on Olympic Dam (South Australia) that it may be possible to discriminate the major fertile hydrothermal systems in an IOCG province using 3D inversion of regional gravity and magnetic data.
The Mumbwa FalconTM survey, covering an area of roughly 50km x 40km, offers a high resolution dataset for which it is appropriate to undertake detailed analysis. The data was inverted on a 100m lateral and 25m vertical resolution, with models extending to approximately 2km below surface. With this approach dense bodies that lie adjacent to or even proximal to magnetic zones, and at similar depths, are also considered to be valid IOCG targets.
Figure 1 provides a plan view of the location of the targets at Mumbwa overlain on a digital terrain image. This is a revised set of targets arising from the 3D inversion of the FalconTM gravity gradient and magnetic data and the neural analysis of these data together with the FalconTM radiometric data carried out in March 2006.
Proposed Drilling Programme:
Table 1 contains the High Priority targets rated for drill testing that the combination of the initial results from the FalconTM survey and the further more detailed 3D geophysical interpretation outlined.
From the nature of the IOCG target geology and the detail of the FalconTM dataset, it is considered feasible to site very accurate drilling locations based on the results of the SolidEarthTM Interpretation.
The initial planning is for all holes to extend to a vertical depth of 500m to ensure that the targets are tested beneath weathering and leaching levels. Most of the targets were identified at this depth but many extend up to much shallower depths and some may even outcrop. The planned primary holes amount to a drilling programme exceeding 5,500m. All holes are vertical except the one designed to test the inferred sub-vertical structure at Kitumba.
High Priority Targets for Drilling - Table 1
Of note is one of the anomalies identified as MUM_S36, is present in the Kitumba Prospect. Striking 2.4km long, 800m wide north-south, the feature corresponds with a strong uranium anomaly on an exposed ridge and is probably related to a major north-south structure. This structure is also mapped as a discrete conductor in the deeper levels of the CSAMT survey. The surface SolidEarthTM feature has not been tested by the historical boreholes, except for KD3 in the extreme north. Borehole KD3/D offered the best copper-gold intersection on the Project to date.
