Ann: VIKING DEFINES HIGH-GRADE GOLD RESOURCE AT FIRST HIT MINE, page-26

Short of requesting a copy of the share register from the company Market Index gives you a top 20 list but note the date of the last update as it can be somewhat behind as it is Annual Report derived.

For most investors this is adequate information, traders might prefer share price and volume movement and look to charts. Everyone else is either just voyeurisitc or have a material intent of some sort.
