La Mancha's 2008 Year End Resources Increase 34% to 1.8 Million Ounces
All amounts are expressed in US dollars, unless otherwise indicated.
HIGHLIGHTS:
- Measured and Indicated resources of 1,774,515 oz of gold - Proven and probable reserves of 710,507 oz of gold - 2009 exploration budget of $7.1 million - Goal of increasing Measured and Indicated resources to 4.0 million ounces by 2011
La Mancha Resources Inc. (TSX: LMA),(hereinafter "La Mancha" or the "Company") is pleased to report that at year-end 2008, the Company's Measured and Indicated resources (thereafter "M&I resources") had reached almost 1.8 million ounces of gold, up 34% compared to 2007 year-end resources of 1.3 million ounces.
Proven and Probable reserves (thereafter "P&P reserves") reached 710,507 ounces of gold at the end of 2008 compared to 688,860 ounces a year earlier. A full description on La Mancha's mineral reserves and resources is provided in the table at the end of this press release.
Michel Cuilhe, President and CEO of La Mancha noted: "The large increase in our M&I resources in the past year is the direct consequence of the intense effort devoted to exploration on our four main properties over the course of 2008. Just as exciting is the fact that last year's exploration work showed and/or confirmed that each of our main properties still has significant potential. Preliminary results of our volcanogenic massive sulphide ("VMS") program in Hassai suggest that we have just scratched the surface of what might become an important gold-copper deposit, while our Frog's Leg mine in Australia delivered another significant resource increase and yet still remains open at depth and to the North."
La Mancha intends to continue to explore its most promising properties with the mid-term goal of increasing its M&I resources to four million ounces of gold by the end of 2011. An exploration budget of $7.1 million is planned for 2009 for this purpose. The following table shows La Mancha's 2009 exploration budget on a country-by-country basis, including the main targets.

SUDAN
Exploration at the Hassai mine in 2008 yielded significant results on two fronts. First, on the gold front, the qualification of 7.1 of the 8.9 million tonnes of tailings accumulated on site during the first 15 years of mine production allowed the addition of 287,000 ounces of gold (114,000 ounces attributable to La Mancha) to M&I resources and 175,000 ounces of gold (70,000 attributable to La Mancha) to Inferred resources. Drilling activities resumed in the first quarter of 2009 to upgrade the tailings Inferred resource to the M&I category, and to qualify most of the remaining 1.8 million tonnes of tailings as resources. The Company expects to provide an update of resources contained into the tailings by the end of the second quarter of 2009.
This new resource, along with the gold contained into the Hassai quartz-type deposit that will continue to be delineated in 2009, will constitute the basis for a CIP/CIL feasibility study expected to be delivered at the end of 2009. An eventual CIP/CIL plant would considerably increase the recovery rate at Hassai, where gold is currently produced through heap leaching.
The other source of exploration success in 2008 was the Hassai VMS exploration program. Preliminary drill results for the first of five locations where VMS have been identified on the Hassai property indicate a minimum conceptual deposit of 20 million tonnes at 1.3 - 1.5 g Au/t and 1.5% - 2.0% Cu, above which an enriched supergene section was later identified. Best results for the supergene section included 33 m at 5.76 g/t Au and 7.16% Cu from 17 m(1), 12 m at 29.6 g/t Au from 6 m(1) and 29 m at 4.8 g/t Au and 3.43% Cu from 21 m(1).

More attention will be devoted to the VMS program in 2009, starting with the analysis of the second of the five VMS targets identified at Hassai, the 2-km long Hadal Awatib pit, which has been drilled both from surface and from the floor of the pit. Drill results for the recently-completed 51 reverse-circulation and diamond drill holes should be available by the end of the first quarter of 2009.
Moreover, a drilling program aimed at defining the first inferred VMS resource at the Hassai pit is currently underway. This program consists of 24 holes totalling 12,160 m of drilling. The program will also test the extension of the sulphide lens at depth (-600 m). The results of both programs will be released at the beginning of the second quarter 2009.
As previously mentioned, preliminary metallurgical testing is about to begin to estimate recovery for the sulphide ore. Results should be included in the preliminary economic assessment to be completed in the second half of 2009.
The Hassai conceptual estimate of potential tonnage and grade to date is based on insufficient exploration data to define a mineral resource compliant with National Instrument 43-101. It is uncertain whether further exploration will result in the target deposit being delineated as a mineral resource. The estimate is based on the current geological interpretation of the lens with the intersections of copper and gold mineralization from the 12 new holes and 7 previously-drilled holes. The estimate excludes copper and gold values outside the interpreted zones and all lead, zinc and silver values, and does not take into account possible enrichment from the upper part of the lenses. The estimate also excludes dilution and recovery.
COTE D'IVOIRE
Ity Mine
In 2008, more than 16,900 meters of resource development drilling were completed at the Ity mine, targeting high potential zones. Of the 310 holes completed, 84% returned favourable intercepts, generating an increase of more than 245,000 ounces of gold in Ity's M&I resources (112,459 ounces attributable to La Mancha), or more than 45% since December 2007. The project's measured and indicated resources now stand at 768,100 ounces of gold (352,558 ounces attributable to La Mancha) compared to 523,091 ounces of gold at December 31, 2007 (240,099 ounces attributable to La Mancha).
Exploration work will continue in 2009 on the grounds of the Ity mine, starting with the analysis of the recently-completed drilling. The focus this year will once again be on some targets in immediate vicinity of the current operation but will also venture onto the east side of the Cavaly river, which crosses the property. The first drill results are expected in the second quarter of 2009.
Bondoukou Prospect
Based on the conclusive results obtained in 2008 at the Bondoukou prospect (100% owned by La Mancha), a first round of drilling is planned on the property in the second half of 2009. The Bondoukou prospect is located near the western Ghanaian border, in an area where large deposits are being mined. Based on a ground survey conducted prior to 2002, two main geochemical anomalies have been prioritized out of six identified anomalous zones. The exploration work completed in 2008 includes detailed geological mapping, soil and rock geochemical sampling and a ground geophysical survey.
AUSTRALIA
La Mancha's main two Australian properties accounted for more than 50% of this year's total increase in M&I resources, with the exploration programs on both properties returning excellent results.
Frog's Leg Mine
M&I resources at the Frog's Leg gold project in Australia have increased by more than 30% compared to the June 2007 resource estimate and by more than 140% compared to the resource estimate of December 31, 2006. The project's measured and indicated resources now stand at 941,000 ounces of gold (479,910 oz attributable to La Mancha), up from the previously-stated 723,000 ounces of gold (368,700 oz attributable to La Mancha).
This year's resource increase can essentially be attributed to the conversion of Inferred resources to the M&I category due to infill drilling that has taken place since May 2007 in the northern extensions of the Frog's Leg deposit and the completion of detailed extensional drilling between the Mist/Fog lodes and the Rocket/Whistle lodes, confirming continuous mineralization between these two orebodies and bridging the 'Gap'.
Priorities for 2009 include completing the review of the mining plan to integrate this year's increase in resources. Expected at the end of the second quarter of 2009, the new mining plan is expected to allow an increase in the Frog's Leg production rate. Moreover, Frog's Leg delineation will continue with a new resource for March 2009, to include underground drilling from the southern extension and "Gap" region drilling. Future drilling underground during the 2009 period will be used to define the Lodes for stoping purposes. White Foil Advanced Project
2008 was very fruitful for White Foil as well. First, the infill drilling program completed in early 2008 prompted a 29% increase in the project's M&I resources to 531,000 ounces of gold. Then, the completion of a positive feasibility study for the first phase of the project allowed an initial reserve estimate to be published for the property. These important accomplishments set White Foil to become La Mancha's fourth producing mine. As the first phase of the project is already fully permitted and requires minimal development, White Foil is expected to start production of 76,000 ounces of gold as soon as a satisfactory milling agreement is signed.
Exploration of Other Tenements
Detailed and comprehensive mapping has been undertaken on Kalgoorlie tenement land holdings. It has indentified additional perspective drill targets around the Park Dam properties, co-owned with Barrick Gold. The Park Dam properties possibly hold the southern continuation of the Frog's Leg shear (Mungari Shear) and the Southern Cross Porphyry. Drill programs of RC will test across these tenements. Additional drilling will take place at the Firefly on the Kurranwang trend, a conceptual target that shows strong magnetic response in aerial magnetic and strong geological characteristic in multi-element and alteration data.

MINERAL RESERVES AND RESOURCES
Mineral reserves and resources have been estimated by La Mancha's technical personnel for each property in accordance with definitions and guidelines adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM "Standards on Mineral Resources and Reserves"). There are numerous uncertainties inherent in estimating proven and probable mineral reserves, including many factors beyond the Company's control. Reserve estimation is a subjective process, and the accuracy of any reserve estimate is a function of the quality of available data and engineering and of 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.

MINERAL RESERVES AND MINERAL RESOURCES
Metallurgical Recovery and Cut-off Grade
In calculating mineral reserves, cut-off grades are established using long-term gold price and foreign exchange assumptions, the average metallurgical recovery rates and estimated production costs over the life of the related operation. For an underground operation, a cut-off grade is calculated for each mining method, as production costs vary from one method to another. For a surface operation, production costs are determined for each block included in the relevant operation.
The following table indicates the cut-off grade calculations and the average metallurgical recoveries at La Mancha's gold mining operations of the proven and probable mineral reserves.
