Orosur Mining Inc. ("OMI" or "the Company"), today announces that further to the option agreement entered into with Gladiator Resources Limited ("Gladiator"), as announced August 4, 2010, Gladiator has earned its first 20% interest in the Isla Cristalina iron ore, manganese ore and base metals prospects in Uruguay after spending in excess of US$1 million in these prospects.

The option agreement provides for Gladiator to earn up to an 80% interest by expending US$1 million to earn 20%, a further US$4 million to earn an additional 31% taking its interest to 51% and finally an additional 29% by preparing a bankable feasibility study. OMI retains the rights to gold, silver and diamonds over the project area.

David Fowler, Chief Executive Officer of the Company, commented: "We are very pleased with the progress that Gladiator has made in the past year since committing to proceed with their option agreement and the continued aggressive program they have planned and funded for 2011 to achieve their 51% interest in the project by spending US$ 5 million. Through the interest that Orosur retains in the project, we are hopeful that Gladiator's continued investment will lead to future revenue for the Company."

Gladiator´s results can be found at www.asx.com.au under symbol GLA in their quarterly report and in investor presentations. The initial drill and test results announced to date by Gladiator have been encouraging, including drilling 60 holes for 3,395 meters yielding the following intersections of interest:

Papagayo:CPRC 008 - 53m @ 26.5%FeCPDD 020 - 39m @ 29.8%FeCPDD 018 - 30m @ 33.2%Fe

Iman:CIDD 023 - 33m @ 29.9%FeCIDD 022 - 18m @ 32.4%FeCIDD 014 - 16m @ 31.6%Fe

Initial assay results for 11 holes received are consistent with test work and confirm that a high quality magnetite concentrate can be produced.

Gladiator expects that the expenditure to earn the next 31% will be completed during the course of the current calendar year.

Gladiator recently appointed Forbes & Manhattan to provide them with strategic and corporate development services.
