Horizon launches a 1-for-8 underwritten rights issue at A$0.30, raising A$23.4m after expenses (82.1m shares), with a free option per two new shares (A$0.35, expiring 28 Feb 2008). Funds replace cash spent on Wei 6-12S appraisal and fund early development work.

What it means for a shareholder

82.1m new shares at about A$0.285 to raise about A$23.4m. That's 11% dilution: every existing holder's slice gets 11% smaller. If you held A$1,000 of shares (3,509 at the issue price), your slice goes from 0.000544% to 0.000483% of the company. To keep it you'd need 447 more shares - about A$127 at the issue price.
