Results of Ground Geophysical Survey in Australia

Toronto, Ontario July 25, 2007:  Simberi Mining Corporation (“Simberi”) (TSXV: SAU) announced today that it has received an initial report on the ground magnetic and gravity surveys of its Lambina project in Australia. The 100% owned property of 1134 sq km consists of two Exploration Licenses (ELA 301/07 and EL 3566) located approximately 65 km northeast of Marla, South Australia.

A ground gravity survey was completed to identify potential anomalies associated with regional airborne magnetic features. Three coincident magnetic and gravity anomalies were defined. The analysis is:

Anomaly LB-02

This is an elongate anomaly with a peak reading of some 4 mGal. The host for the anomaly is estimated to be polygonal in cross section to fit the observed data. The depth to the top is interpreted to be less than 200 metres.

The model uses a density contrast of 0.2 gm/cc which is close to the contrast yielding the best computer fit. The body deepens somewhat if a larger density contrast is assumed and the fit also deteriorates slightly but is probably still acceptable. The main body is quite large – some 6 km long and about 1km wide and it is interpreted to be more than 2.5 km thick with the assumed density contrast.

The anomaly peaks along Profile 2 and the sharpness of this peak suggests that there is possibly a shallower body in this vicinity that appears to come virtually to surface.

Anomaly LB-03

This anomaly is also elongate and was also modeled with a polygonal body. However the Bouguer Anomaly is more intense having a maximum of 6 mGal. The fit to the observed data is reasonable and the interpreted size of the body is some 5 x 1.5 km with a thickness of about 5.5 km assuming a density contrast of 0.2 gm/cc. The body is fairly shallow with an interpreted depth of less than 200 metres. Some portions of the anomaly have fairly sharp gradients which could not be simulated with a polygonal body of constant depth and it is likely that some portions of the body are shallower than given in the model.

Anomaly LB-01

This anomaly was only partially covered by the gravity survey and was not adequate to complete any modeling. The company is reviewing other data to assess the potential of the anomaly.

In addition the data shows a number of lineaments on the property; one in particular strikes in a NW direction along the western edges of anomalies LB-02 and LB-03.  Another, strikes in the same direction some 6 km further to the east.  These lineaments are quite robust and and appear to be supported by both the gravity and magnetic data.  On interpretation is that they are faults that may be defining a NW - trending structural corridor which contains the two anomalies.

In summary a total of four drill holes are recommended, two on each of LB-03 and LB-02. These anomalies exhibit coincident gravity and magnetic anomalies that show similar geophysical characteristics to the Olympic Dam deposit that is the classic model for large mineralized zones in the G-2 corridor.

The LB-02 and LB-03 gravity anomalies of 6 and 4 mGal respectively, combined with the amplitudes of their coincident magnetic anomalies (800 and 1000 nT) suggests geophysical similarities with Olympic Dam.  The latter has a gravity anomaly of 14 mGal and an associated magnetic anomaly of 1000 nT.  The magnetic susceptibility combined with the significant density contrast along with the structural conditions surrounding the anomalies indicate a geological formation that has similar geophysical features as Teck Corporation’s Carrapetenna project and the Prominent Hill deposit, all of which are located in South Australia.

The above geophysical surveys were conducted by Haines Surveys using a Scintrex CG-3M Autograv Gravity Meter which can read to better than 0.01 milligals. All gravity surveys are read in closed loops as regularly as possible. All downloading and processing of the gravity data is highly automated and fully integrated with the GPS solutions. All observations are reduced to Bouguer Anomalies at 2.67 density and connected to the Australian National Gravity Grid. The results were analysed by Barrett Geophysical Exploration Consultants Pty Ltd., Frenchman Bay, West Australia. Doug Barrett is a Qualified Person under the Australian Code who was responsible for the review and analysis of the geophysical data.
