21 Nov 2019capital raising announcement▲ GoodMajor

Winchester raised A$6.4m via a placement of 128m shares at A$0.05, a 14% discount to the 10-day VWAP, led by Gleneagle and CPS Capital. Funds go to Mustang development, Lightning offsets and El Dorado/Spitfire drilling. Twice the August issue price of A$0.025.

What it means for a shareholder

128m new shares at A$0.050 to raise about A$6.4m. That's 19% dilution: every existing holder's slice gets 19% smaller. If you held A$1,000 of shares (20,000 at the issue price), your slice goes from 0.00358% to 0.00291% of the company. To keep it you'd need 4,577 more shares - about A$229 at the issue price.
