Eureka Energy is advising shareholders not to accept the US$110 million offer that was made for the company by Aurora Oil & Gas on Monday.

Eureka asserts the offer is lower than their valuation of the company's flagship asset in the Sugarloaf Field and does not attribute any value to its Pan De Azucar/Black Jack Springs, or Bioche assets.

Eureka owns a 6.25% working interest in 24,743 gross (1,521 net) acres operated by Marathon Oil in Karnes County. In U.S. dollars, the offer is for $0.46 per share and Eureka believes the Sugarloaf field alone is worth US$0.56 per share or US$132.7 million.

If I'm doing the math correctly, that's $132,700,000/1,521 net acres = a valuation of $87,245.23/acre.
