MONTREAL, QUEBEC -- July 20, 2009 - La Mancha Resources Inc. (TSX: LMA)

HIGHLIGHTS:

• Frog's Leg Proven and Probable reserves grow 45% to 789,504 ounces of gold
• New upgraded mine plan converts 86% of M&I resources to reserves
• Average gold output per annum expected to increase 29% to 113,388 oz (57,828 oz attributable to La Mancha) from 2010 onwards

La Mancha Resources Inc. (TSX:LMA) (hereinafter "La Mancha" or the "Company") is pleased to announce that the Frog's Leg Proven and Probable reserves (thereafter "P&P reserves") are up by 37% from the 2007 definitive Feasibility study in light of an upgraded mine design incorporating the significant resource increase of May 2008. With the upgraded mine plan, gold output for the mine is expected to average 113,388 ounces of gold per annum (57,828 ounces attributable to La Mancha), from 2010 onwards, representing a 29% increase over the December 2007 feasibility study average annual gold production estimate, and the mine life is extended by 1.2 years.

The project's P&P reserves now stand at 789,504 ounces of gold (402,647 oz attributable to La Mancha), up 45% from the December 31st, 2008, estimate of 582,918 ounces of gold (297,288 oz attributable to La Mancha).

The following table highlights the changes in the mine's operational and economic profile from 2010 onward:

Michel Cuilhe, President and CEO of La Mancha, stated "Having surpassed the ore production and profitability targets set in the original feasibility study, Frog's Leg continues to exceed expectations with an increased mine life and production profile that should now average 113,388 ounces of gold per year starting in 2010, 29% more than originally expected. The mine continues to show strong growth opportunities for the future, as it remains open to the south and at depth. Moreover, the solidity of the Frog's Leg mine should now enable La Mancha to accelerate the growth of its Australian presence through the development of the nearby White Foil and Park Dam projects."

MINERAL RESERVES AND RESOURCES

La Mancha began updating the Frog's Leg mining plan after completing its ambitious 2007-2008 exploration program that led to a 37% increase in its measured and indicated resource.

"The goal for the mining team was to develop a mine plan that would capture the maximum of this additional value for our shareholders. Dozens of scenarios were considered. We found that extending the "Rocket" decline was the only scenario that allowed both an increase in early production and maximized conversion of resources into reserves," stated Bill Plyley, La Mancha's Chief Operating Officer.

Figures 1 in Appendix A, show the evolution of the mine plan relative to the one in the 2007 feasibility study. The extension of the decline below the pit will provide access to the newly-expanded Rocket ore zone at depth and to the new "Gap" area, where mineralization was identified in early 2008, while the relocation of the second decline to the north will provide more efficient access to the Mist/Fog ore body. This upgraded mine design allows for an 86% conversion rate for the latest Frog's Leg measured and indicated resource, and adds 243,723 ounces of gold to its P & P reserves, which are up 45% at 789,504 ounces (402,647 ounces attributable to La Mancha) as at April 1, 2009 compared to 2008 year end reserves.

Based on the new mine design, the Frog's Leg mineral reserves and resources are as follows:

Table 2

The mineral reserves were estimated in accordance with definitions and guidelines adopted by the Canadian Institute of Mining, Metallurgy and Petroleum. They were calculated using a mining cut-off grade of 3.0 g/t, standard dilution parameters applied to the resource based upon empirical knowledge of the Frog's Leg rock conditions and industry standards, mining methods, pillar and panel recoveries, standard assumptions on mine design made to suit operating equipment parameters and AMC Consultants Pty Ltd benchmarks. An updated technical report will be filed on SEDAR within the next 45 days in accordance with National Instrument 43-101 for mining projects.

As shown in the table below, this proven and probable reserve estimate represents an 86% conversion from the Measured and Indicated resource reported in May 2008.

Table 3

The new Frog's Leg mine design is expected to boost average gold output to 113,388 ounces per annum (57,828 ounces attributable to La Mancha) from 2010 until the beginning of 2016, representing a 29% increase over the previous mine plan, while extending the mine life by 1.2 years. The new mine plan provides for the extraction of 4.89 million tonnes of ore at a fully diluted grade of 5.0 g/t Au for 789,504 oz recovered over a remaining mine life of 7.1 years, thus increasing the total gold output over the life of the mine by 37% .

As seen in the table below, an increase in the production rate is anticipated from 2010 onwards. This will be achieved through an expansion of the mining fleet and workforce. Allowances for this equipment and manpower have been made in the financial evaluation of the project. The Rocket decline has already progressed beyond the original feasibility design and is currently producing ore from both development and stoping.

The mining method is longhole open stoping. Mining will continue progressing in a top down manner to allow for earlier stoping cash flows under shallow, favourable geotechnical conditions. Stopes are currently left open using sill and island pillars to provide stability, but a paste fill plant is scheduled to be built and operational by mid-2010, which will eliminate the need for pillars and improve mining recovery. The Frog's Leg underground mine design was based on resource estimate block modelling information provided by La Mancha and CSA Australia Pty Ltd.

Based on the above-mentioned mineral reserves, the Frog's Leg revised production profile is as follows:

ABOUT THE FROG'S LEG MINE

The Frog's Leg mining project is a joint venture between La Mancha Resources Australia (51%) and Dioro Exploration NL (49%). The project is situated 25 km west of Kalgoorlie-Boulder in the Eastern Goldfields of Western Australia. The Frog's Leg deposit was discovered in late 1999, put to production by the previous operator in April 2004 via open pit mining, and shut down in 2005. The property remained on care and maintenance until 2006, when La Mancha began a significant Diamond drilling program aimed at outlining sufficient resources for an underground mining operation. Following successful drilling programs and resource increases, a positive feasibility study was issued in December 2007. Frog's Leg was successfully converted into an underground mine, with the first gold pour occurring on May 13, 2008, less than 12 months after construction began. Since then, the mine has steadily increased its performance, and was considered to have met commercial productio n criteria on January 1, 2009.

The mine is currently producing ore from development drives and stopes. The following table outlines the mine's activity since underground activities began in 2007:

Joe McDiarmid, BSC, BEng(Mining), AusIMM, Underground Mining Manager, Frog's Leg, La Mancha Resources Australia, supervised the study and all of the information contained in this release.

Frog's Leg mineral reserve estimates were evaluated in accordance with definitions and guidelines adopted by the Canadian Institute of Mining, Metallurgy and Petroleum. They were calculated using a mining reserve cut-off grade of 3.0 g/t, standard dilution parameters applied to the resource based upon empirical knowledge of the existing Frog's Leg Underground mine conditions and industry standards, mining methods, standard assumptions on pit design made to suit operating equipment parameters and consulting benchmarks.

There are numerous uncertainties inherent in estimating mineral reserves, including many factors beyond the Company's control. Resource estimation is a subjective process, and the accuracy of any resource estimate is a function of the quality of available data and engineering and geological interpretation and judgment. Results from drilling, testing and production, as well as material changes in metal prices subsequent to the date of an estimate, may justify revision of such estimates. To the best of La Mancha's knowledge, at the time of estimation there were no known environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant issues that would materially impact on the eventual extraction of the mineral resources. An updated Technical Report will be filed with SEDAR within the next 45 days in accordance with National Instrument 43-101 for mining projects.

The effective date of the mineral reserve estimate is April 1, 2009. To La Mancha's knowledge, the reserve estimates are not materially affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

The updated resource review and estimation conforms to the requirements of NI43-101 and the CIM Best Practices for Estimation of Mineral Resources.
