Innamincka Petroleum shares staged another massive run yesterday, leaping 46 ¢ to a peak of $1.22 after the company found oil and gas in a wildcat well in the Cooper Basin in South Australia.

The shares surged after Innamincka announced that light sweet crude had flowed at a rate of 600 barrels a day from the Flax-1 well, adding to the natural gas also produced in the well.
