why hasnt drilling started yet, page-4

Best answer to that appears to be the following...

Deposit "appears" unviable from available information.

High grade material for Sino Shipment apparently was sourced and blended from the "stringers" which are a very small percentage of the overall deposit.

See below for Pit diagram size and deposit grade / strike information sourced from the company presentation 31/8/12

As can be seen the main reef is 50cm thick and dips at 42º which is not economic to mine due to the high strip ratio required.

The main reef appears to be broken and fragmented as it doesn't appear to follow a clear and consistent path throughout the length of the pit.

The blue dots are existing drill holes that missed mineralisation all together.

Yellow are hits.

Very hit and miss suggesting inconsistent mineralisation with low probability of being a long term producing mine.

Would take a considerable number of holes over a larger area to identify and delineate a JORC complaint resource.

Hence my best guess would be no drilling as further drilling may not be useful in supporting the share price.
