 Notes:

1.     Drillholes prefixed with MXD have been drilled by MetalsEx since November
2005 and consist of diamond drill core with a minimum core diameter size of HQ3
(61mm).

2.     Collar Coordinates are the coordinates of the collar of the drillholes.
The drillholes are inclined -60degrees from horizontal, excepting MXD22,23 (-70
degrees) and MXD25 (-58degrees), and orientated towards a grid azimuth of 100
degrees (easterly). Each drillhole is planned to intercept the mineralisation at
90 thus mineralisation 'interception' widths are close to actual or 'true'
widths. In general the drillholes are drilled on a grid spacing of 100 metres
apart.

3.     Reporting of the above composited intercepts was determined by applying
an upper and lower boundary defined by a low grade cut-off of 0.7g/t Au. Some
composited intercepts include single metre, internal intercept grades of less
than 0.7g/t Au. Isolated single metre intercepts are not reported unless
considered to be significant. No high grade cut-off has been applied to the
individual gold or molybdenum assays.

4.     MXD25 is a re-drill of hole MXD24 which was abandoned after intercepting
a cavity near the surface. It is also the first drillhole results to be obtained
outside of the current resource area. The mineralisation intercepted is from the
footwall zone only.  The hangingwall zone was not intercepted as it is
interpreted as having been eroded away.

The results from drillholes MXD16 to MXD22 are located within the previously
reported JORC inferred mineral resource of 23 million tonnes at an average grade
of 2.3g/t Au and 0.07% Mo.  Drillhole MXD25 is the first drillhole to be drilled
outside of the boundary of the resource.

The Company is currently extending the resource by drilling areas uphill to the
east and to the north.  The results from the latest drillholes have confirmed
the size and grades of the recently announced JORC inferred mineral resource
estimate thus indicating the potential to upgrade the current resource from JORC
inferred to JORC indicated category.

The results of MXD25 have demonstrated the immediate potential to expand on the
size of the current resource towards the east. It is important to note that the
drillhole has been interpreted as having only intercepted the footwall zone of
the mineralisation. It is interpreted that the hangingwall mineralisation has
already been eroded away, thus was not able to be intercepted by the drillhole.

RUNRUNO - SAMPLING & ANALYSIS

Sample Preparation

The drill core is taken from the drill site to a secure compound at the
Company's field camp and is logged by the geologist. The drill core is then
split into two equal halves along its long axis, with one half being sampled at
predetermined intervals, bagged and sent for analysis. The remaining half-core
is retained in core boxes and stored on site for future reference.

The bagged half-core samples are being submitted to an independent 'ISO17025
accredited' laboratory for sample preparation and analyses for gold and
molybdenum. All of the half-core samples are crushed by the laboratory and a
900-1000 gram split is taken, pulverized and presented for analysis.

The remaining crushed sample is retained in bags and stored at the laboratory
for a period of three months before being returned to the Company for storage.
These remaining crushed samples will be used in the future for additional
analyses for gold, molybdenum, silver, sulphur and other elements as deemed
necessary, for example, for resource estimation work.

Analytical Techniques

Gold:           Gold analysis is by classical 'Screen Fire Assay' technique that
involves sieving a 900-1000 gram sample to 200 mesh (75microns). The entire
oversize and duplicate undersize fractions are fire assayed and the weighted
average gold grade calculated. This is one of the most appropriate methods for
determining gold content if there is a 'coarse gold' component to the
mineralisation.

Molybdenum:    The sample is dissolved in Aqua Regia (3:1 HCl:HNO3) and
Molybdenum analysis is carried out by Inductively Coupled Plasma - Optical
Emission Spectrometry (ICP-OES) method.
