Not sure why you feel widths of 9 metres or more are necessary.The LSG Timmins results with thick widths occur in a porphyry unit which is different from the gold bearing quartz veins on the GM and vicinity. The GM veins range from 1 to 3 metres, which is within the normal range for these type of deposits. Check the following reference : http://gsc.nrcan.gc.ca/mindep/synth_dep/gold/greenstone/index_e.php

The article is entitled " Greenstone-hosted Quartz-Carbonate Vein Deposits by Benoît Dubé and Patrice Gosselin " Some key extracts from that article are :

Individual vein thickness varies from a few centimetres up to 5 metres, and their length varies from 10 up to 1000 m. The vertical extent of the orebodies is commonly greater than 1 km and reaches 2.5 km in a few cases (e.g. the Kirkland Lake deposit, Charlewood, 1964).

The average gold grade of world-class Canadian deposits is 10 g/t, which is slightly higher than the average for this type of deposit worldwide (7.6 g/t).

Clearly everyone's patience is being tested as we await the next GM results.
