The offer, in which Tomahawk is offering six of its shares and one option for every 10 shares and two options in K2, was originally meant to close in a week, on May 23.
But the two companies have now announced that the offer would now close on June 6.
They said as of yesterday, Tomahawk owns 39.26% of K2’s shares and 28.03% of its options.
Under the merger, Tomahawk plans to issue a total of 51.6 million shares and about 28 million options to K2 investors.
K2 listed on the Australian Securities Exchange in March after raising about $12 million to invest in oil and gas drilling projects in Texas, Michigan, Louisiana, Illinois and Alabama.
