La Mancha Resources Inc. (TSX:LMA), (hereinafter "La Mancha" or "the Company") is pleased to report that the 42 short and long holes drilled from the bottom of the Hadal Awatib pits at the Hassai property have returned high-grade gold, copper and silver values. Drill results are shown in Table 1 and 2 appended to this press release. These preliminary results A) suggest the presence of an enriched supergene zone at the top of the previously-identified volcanogenic massive sulphide (VMS) lens under these pits and B) confirm the presence at depth of a feeder zone adjacent to the massive sulphide lens. Some drill holes also intersected massive sulphides with elevated zinc and silver values.

The Hadal Awatib AB and CD pits are part of the second VMS target being explored on the Hassai property. As shown in Figure I, attached to this press release, most of the holes in this phase of the program were drilled from the floor of the existing pits. This second supergene zone seems to have a lower gold content than the supergene section identified on the first VMS target (the Hassai pit), but shows indications of surprisingly high copper grades (1 meter at up to 20.5% Cu) and silver content (up to 258 g/t Ag). These high grade results coupled with the width of the Hadal Awatib AB pit suggests that a significant portion of this enriched zone would be minable by open pit methods. Moreover, the identification of the stringer zone shown in Figure 2 increases the likelihood of confirming more high-grade mineralization in the area.

Michel Cuilhe, President and CEO of La Mancha, noted: "We are delighted by these results, as some of the intersections obtained from this second enriched zone compare favourably with some of the world's richest polymetallic deposits. The fact that some of these high-grade results have been intersected near the bottom of the pit, in an area where they would be easily minable by open-pit mining methods, adds to their quality, as this suggests that the exploitation of the two supergene zones in the early stage of the project could guarantee an early payback on the investment."

To date, the 75 holes drilled, totalling 8,504 meters, have allowed La Mancha to begin delineating two of the six VMS targets identified at the bottom of previously-mined pits at its Hassai property. While some of these holes were drilled from surface to intersect the massive sulphide lenses in the primary zone at depth, other holes were drilled from the floor of the existing pits in an effort to identify an enriched zone (supergene). The results of this exploration effort have confirmed the presence of a VMS massive sulphide lens under each of the Hassai and Hadal Awatib pits, and suggest the presence of an enriched zone at the top of each of these VMS lenses. The conceptual tonnage and grade of the primary zone of these first two targets were estimated using a manual polygonal method with parallel cross-sections spaced at 100 m. This estimate suggests a total potential to date of 60 million tonnes at 1.15-1.35 g/t Au and 0.9-1.3% Cu. The two supergene zones identified should add significantly to this.

The Hassai and Hadal Awatib conceptual estimates of potential tonnes and grade to date have insufficient exploration 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 used the current geological interpretation of the lens with the intersections of copper and gold mineralization from the 12 new holes drilled to date and 7 previously-drilled holes at the Hassai pit and 8 new holes drilled to date and 7 previously-drilled holes at the Hadal Awatib pit. 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, mainly below the west pit of Hadal Awatib. The estimate also excludes dilution and recovery.

La Mancha decided to initiate an exploration program entirely devoted to the VMS potential of its 40%-owned Hassai mine in December 2007 on the basis of historical results of drilling by BRGM in the 1980s and 1990s. The objective of the first phase of the program was to test the potential of two of the six most prospective VMS lenses identified at the bottom of the previously-mined pits.

The presence of strong supergene enrichment similar to Hassai at the second target enhances the potential of this deposit, which is displaying a growing number of similarities with the Bisha deposit in neighbouring Eritrea.


Forty-two holes totalling 3,212 meters were drilled from the floors of the Hadal Awatib AB and CD pits. More information on these holes is shown in Table 1 and Figure 1, attached to this press release. The holes were drilled down dip within the lens in the CD pit and obliquely in the AB pit, as shown in the five cross-sections in the appendix.

The portion of the VMS deposit that lies below the Hadal Awatib AB pit comprises a very large massive sulphide lens with a significant copper-rich stringer zone along the stratigraphic footwall. The copper stringer zone contains 15-40% sulphides, including chalcopyrite (CuFeS2), pyrite, magnetite and sphalerite (ZnS), as well as quartz, chlorite and minor carbonate minerals. The stringer zone is gradational, with a copper-enriched basal massive sulphide. Both are present on the inside of the (probable) overturned anticline shown in Section D-D.

Like at Hassai, three main types of enrichment have been identified:

- A gold-enriched, copper-depleted zone close to the floor of the pit;

- A gold- and copper-enriched zone at depth; and

- Localized zones of silver and zinc enrichment in addition to good copper and gold values.

Some additional holes are currently in progress (see Figure 1) to allow La Mancha to complete a first 43-101 resource calculation, expected to be released in the third quarter of 2009.

It should also be noted that the area between the AB and CD pits has not yet been drilled as it is currently being mined, but the enrichment can be expected to continue in this area (see Figure 1).

"Given the high gold grades currently being mined from the oxidized zone just above, this unexplored area should return results similar to those obtained from the enriched zone below the AB pit," said Jean-Jacques Kachrillo, Vice President Exploration for La Mancha.


The VMS exploration program will continue as planned, with results disclosed as they become available. The following table outlines the expected news flow for the program, along with the expected news release dates.

Mr. Kachrillo is Vice President Exploration and a full-time employee of La Mancha Resources. He has sufficient experience in the style of mineralization and type of deposit to qualify as a Qualified Person as defined in "National Instruments 43-101, Standards of Disclosure for Mineral Projects". Based on his information, Mr. Kachrillo has consented to the content of this press release in the form and context in which it appears. Mr. Kachrillo has read National Instrument 43-101 and has ensured that this press release has been written in compliance with that instrument.

Analysis of the recent samples complied fully with the Analytical Quality Assurance Program put in place by La Mancha to control and assure the analytical quality of assays in its gold and base metal exploration. This program includes the systematic addition of blank samples, pulp duplicates and internal material references ("standards") to each batch of samples sent for analysis. Blank samples are used to check for possible contamination in laboratory, duplicates allow the overall precision to be quantified and standards determine analytical accuracy. All samples are half HQ or NQ diamond drill core or RC cuttings sampled on a one-metre basis. Samples were assayed at the ISO 17025-qualified Intertek laboratory in Indonesia using fire assays on 30g samples followed by AAS for gold and triple acidic digestion followed by AAS for base metals. The average true widths are more than 60% of the intersection length.


The Hassai mine is located in the Red Sea Hills desert of northeastern Sudan, some 450 km from Khartoum. Inaugurated in 1992, it is Sudan's first and only producing gold mine. Twelve pits have been mined over the years, generating a cumulative production of more than 2 million ounces of gold. La Mancha owns 40% of the mine through a subsidiary and is the mine manager. The Hassai mine's exploration budget is expected to total $4.9 million in 2009 ($2 million attributable to La Mancha), distributed among several gold (quartz, SBR and tailings) and VMS targets. The Hadal Awatib pit is 13 km from the Hassai camp and comprises three main pits (see schematic map in the appendix), where around 1.1 million ounces have been mined since the creation of AMC, a La Mancha subsidiary, in 1992.
