Luiri Gold Releases Further Assay Results of the 2009 Drilling Programme at the Luiri Hill Project
TORONTO, CANADA--(Marketwire - Dec. 17, 2009) - Luiri Gold Limited (TSX VENTURE:LGL)(ASX:LGM) has released the assay results from a further 23 drill holes of its plus 9,000m RC drilling programme (61 drill holes) at the Luiri Hill Gold Project (News Release December 2, 2009).
The results continue to confirm that the Matala deposit is consistently mineralized over significant widths and strike length and show that the wider mineralization zone is possibly more continuous especially at shallower depths in the central zone (Figure 1). Drilling is in progress to better delineate this central thicker zone.
Highlights from the recently received results are included in the table below.

Drilling Results
The results of the current drilling show that there is the potential for the wider mineralization to extend further in the central area. Previous interpretations modeled two wider mineralized zones, the western and eastern, separated by the thinner mineralized zone (Figure 1). However, this was based on a single drill hole (MTL001) from previous explorers and only the gold grade information was available. There was also a significant length of the drill hole where the gold grades were either missing or not sampled. Drill hole MTLRC116 from the current programme has intersected the mineralized zone within 15 meters of drill hole MTL001 and, as reported in this new release, has returned an estimated true width of 14 meters at 4.7 g/t Au. This intersection is also well supported by MTLRC139 with similar widths and grades.
A drilling programme has started with the purpose to confirm the extent of the wider mineralized zone.
A number of the drill holes, especially in the west, which ended in mineralization have been deepened during the December drilling programme. However most have been delayed so that the drilling of the wider central zone can take priority. The deepening drill programme will be continued in January.
A total of 6,077m of RC drilling (61 drill holes) of the 9,500m drill programme was completed during October and December 2009 at the Matala deposit by Boart Longyear using two RC drilling rigs. Only those sections of the drillholes which were identified as covering the mineralized Matala zone were submitted for analysis.
The drilling programme has been focused on the shallower portion of the deposit where initial pit optimization studies have identified the most likely areas that could fall into economic pit studies.
Figure 1 shows the projected intersections of mineralization in drill holes on a longitudinal section of the Matala deposit for the previous drilling programme and the current infill drilling programme reported to date. It also shows the extent of the previous estimate of the wide mineralized resource model.

About Luiri Gold
Luiri Gold is a gold focused company with a strategy of creating shareholder value through building Luiri into a geographically diversified gold resource company in Africa with assets potentially ranging from near term production to exploration properties. The current focus is at Luiri Gold's wholly-owned Zambian subsidiary, Luiri Gold Mines Limited, which holds mineral tenements within southern-central Zambia covering approximately 1,200km2 of highly prospective exploration ground focused on the Dunrobin and Matala gold deposits. The Luiri Hill Project is situated approximately 120km west-northwest of the Zambian capital of Lusaka in Zambia's Central Province. Access to the Project area is by a newly-upgraded paved road from Lusaka.
The current Mineral Resource at the Luiri Hill Project includes 656,000 ounces gold contained in 7.1 million tonnes at 2.9g/t for the Inferred category and 144,000 ounces gold contained in 2.2 million tonnes at 2.1g/t for the Indicated category (reported in Press Release April 15, 2008).
In addition to the substantial gold resources the Luiri property also hosts the large, prominently outcropping hematitic Nambala iron deposit. A review by Coffey Mining indicated that on part of the mineralized body there exists the 'mineral potential' of between 100 and 300 million tonnes of rock at grades of 55-60% Fe. Interpretation of the regional geology indicates that the tonnages contained in this deposit could be significantly larger than this figure. It should be noted that the potential quantity and grade is conceptual in nature, and that there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Luiri Gold's mineral tenements and the resource estimate are the subject matter of two Technical Reports which are available for review under the Company's profile at [ www.sedar.com ].

Note: * The Matala deposit down hole lengths have been corrected using the down hole survey of the intersection and the local modeled dip of the mineralization. As the drill holes have been drilled perpendicular to the strike, no correction has been made for azimuth as the maximum deviation is less than 10 degrees. A cutoff grade of 0.5g/t Au has been used to define the boundary of the mineralized intersection. Gold accumulation is the weighted gold grade (g/t) multiplied by the width of the intersection (meters).
All samples were split using Jones rifflers and collected in plastic bags. The targeted depths were supplied to the geologist on each rig. The samples were submitted to Genalysis Laboratories in Johannesburg for sample preparation and analysis for gold by Fire Assay technique, followed by an atomic absorption spectrometer (AAS) reading. Sample pulp is despatched from Genalysis Johannesburg to Genalysis Perth for the multi-element analysis including copper by Aqua Regia dissolution, followed by an ICP-MS reading.
A Quality Assurance/Quality Control (QA/QC) program forms part of the drilling, sampling and assay program on the Luiri Hill Gold Project. This program includes chain of custody protocol as well as systematic submittal of certified reference materials, duplicates and blank samples into the flow of samples produced by the drilling. The approach is covered in the previous Technical Reports prepared according to the NI43-101 and lodged under the companies profile on the Sedar website.
An independent review of the sampling programme was undertaken and found that the RC sampling and quality control procedures are appropriate and conform to industry standard procedures.
