A U.S. prospectus and an Australian prospectus for the Rights Offering are expected to be sent to shareholders on or about 8 April 2013. The Rights Offering will be made to shareholders in both the USA and Australia. The rights to be issued in the Rights Offering will not trade on the ASX or the NYSE MKT as the issue is non-renounceable.On a fully subscribed basis, the Rights Offering would raise A$17.5 million (US$18.1 million), which together with the already completed placement, would represent a total raising of approximately A$20.2 million (US$20.1 million). Samson intends to use the proceeds of both offerings to fund a portion of the Company's 2013 calendar year capital budget, which calls for drilling six infill development wells in the North Stockyard oilfield in Williams County, North Dakota, along with the first exploratory well in its South Prairie Project in Ward County North Dakota, as well as for general corporate purposes, working capital needs and possible future acquisitions.
