Ann: Bryah Responds to Market Volatility, page-21

Get it from ASX announcements. The CEO/ Chairman has been buying too, now has 68 million shares ie 10.7%, Marc Chan owns 100 million shares or 13.57% and Huang Gang 103 million shares or 14.03% . The CEO's wife owns another 66 million shares or 8.93%
Top 20 previously owned 96%. Now it must be 98%.
I would be in the top 20, but I deliberately have my holdings in two separate SMSF accounts.
There are only 50 people who own more than 100,000 shares outside the top 20. Thats partly why its only small trades and its not widely traded.

Substantial shareholder announcements in the last few weeks.

Very few investors understand alloy smelting and also unaware that OM Sarawak has the lowest power prices in the industry. Half their competitors in Europe have gone broke, South African smelters on their last breath of air. S32 Temco smelter in Tasmania is on the verge of closing. All due to high power prices.
