April 26 (Reuters) - Oil and gas producer Hess Corp (HES.N) on Wednesday topped Wall Street's first-quarter profit estimates and disclosed its consortium with Exxon Mobil Corp (XOM.N) made a new discovery off the coast of Guyana. Hess holds a 30% stake in the consortium, and said the discovery may help justify a new oil project. Production from Hess' share of output in Guyana was 12% above estimates at 112,000 boepd. The company expects current quarter production of between 105,000 boepd and 110,000 boepd due to planned maintenance at the Liza phase 2 platform. On a per share basis, the company reported a profit of $1.13 for the first quarter and an adjusted profit of $1.30.
