La Mancha Resources Inc. (TSX: LMA) (hereinafter 'La Mancha' or 'the Company') is pleased to report the trench results from the Tumluk prospect at its 70%-owned Nuba Mountains project in Sudan. Surface samples contain up to 4.96 g Au/t, 24.7% Pb and 26.3% Zn, confirming the high prospectivity of the project area. Detailed results are reported in Table 1 at the end of this press release.
Dominique Delorme, President and CEO of La Mancha, noted: 'The results announced today are significant because they suggest that the Nuba Mountains project shares several similarities with the Hassai mine. The Tumluk prospect, the source of today's results, is just one of many ironstone gossan prospects in the project area. The Nuba Mountains are interpreted as being part of the Arabian-Nubian Shield, a region that is gaining increasing recognition as one of the world's most promising exploration and mining districts. La Mancha has a major foothold in this very prolific area, with a total land package of over 25,000 square kilometres in the heart of the shield. La Mancha has over 20 years of mining experience in the area, and is ideally positioned to continue responsible development of this region.'
As shown on Figure 1, the Nuba Mountains property is located in central Sudan in the state of South Kordofan, approximately 400km south-southeast of Khartoum. The property covers an area of approximately 5,960 square kilometres at the northeastern edge of the Nuba Mountains. The main prospect identified to date on the property has been named Tumluk (see Figure 2). This area is interpreted to be the southwestern extension of the highly-prospective Nubian Shield, host of La Mancha's 40%-owned Hassai mine in Sudan and Nevsun Resources' Bisha mine in Eritrea.
The first phase of exploration was conducted during the dry season between November 2009 and May 2010. Exploration targeted prominent ridges of gossan and ironstone within a geological sequence that contains felsic volcanic rocks and shows many similarities to the geological setting of the deposits at Hassai. Geological mapping, soil sampling and gravity surveys were conducted over eight of the best prospects, including Tumluk, one of the most promising.
GEOLOGICAL BACKGROUND
As shown in Figures 3 and 4, nine trenches were sampled at the Tumluk prospect along a 500m zone showing artisanal mine workings, surface geochemical anomalism and outcropping ironstone 'gossan'. The trenches revealed shallowly northwest dipping, strongly weathered and deformed schist with zones of alteration. Zinc anomalism is associated with the outcropping ironstone gossan formation, with gold and base metal anomalism associated with the alteration zones in the strongly oxidized schist. The projected extensions of the mineralised zones are covered by thin alluvial sediment deposits concealing the possible continuations of the mineralisation. The picture in Figure 4 shows the terrain of the Tumluk prospect area and several of the anomalous trenches. The ironstone gossans are similar to those at Hassai, which formed over weathered volcanic massive sulphide deposits and contain economic levels of copper and gold.
NEXT STEPS
A ground electromagnetic (EM) geophysical survey is planned for Tumluk during the next field season to supplement results from the gravity and soil surveys, because coincident EM and gravity anomalies commonly indicate the presence of conductive massive sulphide bodies at depth. This exploration technique has been used with success at Hassai and Bisha and is effective even in areas where recent alluvial sediments conceal the basement geology. An initial drilling campaign is scheduled for 2011 once results from the geophysical survey have been analysed. Drilling is required to fully evaluate the initial promising results obtained from surface sampling. Detailed geophysical surveys will also be carried out on several other prospects.
TECHNICAL NOTE
The technical information in this news release was prepared under the supervision of Jean-Jacques Kachrillo and Martin Bennett, both Qualified Persons under NI 43-101. Mr. Kachrillo is Vice President Exploration and a full time employee of La Mancha Resources. Mr. Bennett is Exploration Manager and a full time employee of La Mancha Resources. They have 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 their information, Mr. Kachrillo and Mr. Bennett have consented to the content of this press release in the form and context in which it appears. Mr. Kachrillo and Mr. Bennett have read National Instrument 43-101 and have ensured that this press release has been written in compliance with that instrument.
The recent samples were analysed in accordance with La Mancha's established Analytical Quality Assurance Program, put in place to control and assure the analytical quality of assays performed for the purposes of the Company's gold 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 the laboratory, duplicates allow the overall precision to be quantified and standards determine analytical accuracy. All samples are rock chip samples collected systematically along either 1 or 5m-long intervals from a trench approximately 1m deep, where a bulldozer has scraped the surface scree and soil material away. Samples were crushed and pulverised in Sudan and sent to the Intertek laboratory in Indonesia for routine analysis using fire assays on a 30g sample followed by AAS for gold and acid digestion with ICP for base metals, with samples exceeding the upper detection limit re-assayed by triple acid digestion and AAS finish.
