May 28, 2009 (TheNewswire.ca) --
May 28, 2009, Benton Resources Corp (TSXV:BTC) (BTC: V) is pleased to inform its shareholders of the following news from Coro Mining Corp (OOTC:CROJF) (TSX:COP) ("Coro") announced this morning. Benton has a 34% interest in Coro and a 45% interest if warrants held by Benton are exercised. Benton's Management believes the investment in Coro is a tremendous asset to Benton's shareholders given Coro's advanced San Jorge Copper Gold project in Argentina and other assets such as the Llancahue property joint ventured with Freeport McMoRan Exploration (NYSE:MMR) Corporation in Chile.
Coro Mining Corp. ("Coro" or the "Company")(TSX Symbol: COP) is pleased to announce that Freeport-McMoRan Exploration Corporation ("Freeport") has completed a 7 hole, 1300m reverse circulation drill program at Coro's Llancahue prospect, located 38km south west of the city of Talca in central Chile, as required under the terms of the Talca Belt exploration agreement, announced in the Company's news release dated August 11th 2008. One of these holes, LLA-07, designed to test copper mineralization exposed in a small shaft at the edge of a covered area, intersected 100m at 1.375% CuT + 0.015% Mo+ 3.8g/t Ag from 10m to 110m. The hole was drilled at an inclination of -65 degrees, terminated at a depth of 220m and intersected thin zones of oxide and mixed oxide/chalcocite mineralization before entering primary mineralization at 24m depth. Details of the individual mineralized zones are shown on the table below.

Alan Stephens, President and CEO commented, "We are very pleased to see that drilling at Llancahue has intersected a significant zone of good grade copper mineralization and look forward to receiving the results of the ongoing surface exploration from our partners, shortly."

Mineralization intersected in LLA-07 is hosted by a porphyritic diorite, brecciated in part, with moderate to strong phyllic (silica - sericite - tourmaline - biotite) alteration and quartz-chalcopyrite veinlets. From 110-220m, the hole intersected a porphyritic diorite with propylitic (magnetite - silica - epidote - chlorite) alteration, disseminated pyrite and copper grades averaging less than 0.10%CuT.
