9 Nov 2017capital raising announcement▲ GoodMajor

Comet Ridge raised $10m through a placement of about 42.6m shares at $0.235, a 14.5% discount to the 5-day VWAP, and offered a Share Purchase Plan of up to $3m at the same price. Funds go to Mahalo, the Albany appraisal and working capital. The price is well above June's $0.125 raising.

What it means for a shareholder

42.6m new shares at A$0.235 to raise about A$10.0m. That's 6.5% dilution: every existing holder's slice gets 6.5% smaller. If you held A$1,000 of shares (4,255 at the issue price), your slice goes from 0.000689% to 0.000644% of the company. To keep it you'd need 293 more shares - about A$69 at the issue price.
