Minco Silver Announces Purchase of the Changkeng Gold Project - Seite 3
Changkeng Gold Project
The Changkeng Project falls into the broad category of sediment hosted epithermal deposits. Gold mineralization occurs as lenticular bodies in the brecciated Triassic classic rocks at the upper portion of the synform zone. The gold zone tends to pinch out toward the hinge of the syncline where it is replaced by silver mineralization at the Fuwan Silver Deposit.
Resource Estimate
An updated independent resource estimate was calculated by P&E Mining Consultants and released on March 25, 2009. The estimate contains indicated gold ("Au") resources of 4.0 million tonnes @ 4.89 g/t Au for a total of 623,100 oz Au and inferred resources of 4.0 million tonnes @ 3.01 g/t Au for a total of 386,800 oz Au. Minco Gold has 51% ownership of the Changkeng Project.
Diamond drill data from a total of 127 drill holes and 13 surface trenches were used for the resource calculation of which 59 are new holes completed in 2008. The drilling to date was conducted on an approximate 40 metre section spacing with holes on section between 20 metres to 80 metres apart. Drilling prior to 2007 was undertaken by the Chinese Government 757 Exploration Team. Grade interpolation was undertaken with the inverse distance squared estimation method.

- Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
- The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or
