TULU KAPI RESOURCE INCREASE - 1.38 MILLION OUNCES

Nyota Minerals Limited ('Nyota' or the 'Company')

 

TULU KAPI RESOURCE INCREASES TO 1.38 MILLION OUNCES OF GOLD

 

 

HIGHLIGHTS

 

·; Total Inferred JORC Resource increased from 690,000 ounces to 1.38 million ounces of gold

 

·; 1.38 million ounces of gold represents a 38% increase on Nyota's previously stated objective of a 1 million ounce resource target and a 100% increase on the maiden inferred resource announced in September 2009

 

·; Drilling programme is continuing in order to provide the data required to convert the Inferred Resource to an Indicated category and further increase the size of the resource in the Inferred category

 

 

Nyota is pleased to announce an increase in the Inferred Resource at the Company's Tulu Kapi Gold Project in Ethiopia to 1.38 million ounces, defined at a cut off grade of 0.50g/t Au.

 

Details of upgraded resource statement

 

The resource statement follows the compilation and technical interpretation of 4,579 metres of reverse circulation ("RC") drilling by independent consultants Venmyn Rand. Estimation was based on the data from the maiden inferred resource and verifiable data collated from a further 25 reverse circulation ("RC") drill holes for which assay data has been received. Assay data for the balance of 10 RC holes that make up this particular drill programme will be incorporated into future resource estimations.

 

The drilling focused on the NE extension of mineralisation which is contiguous with the area over which the 690,000 ounces of gold comprising the maiden resource was defined. In addition, Nyota completed an infill drilling programme between drill traverse lines to increase the level of confidence attributable to earlier diamond drilling.

 

 

The results of the upgraded resource calculation at differing cut-off grades are shown below:

The Company expects gold grades at different cut-offs to improve in parallel with the closely spaced infill diamond drilling programme currently underway.

 

Melissa Sturgess, Chief Executive Officer, commented:

 

"We will undertake further localised drilling to upgrade the Inferred resource to an Indicated category in order to provide the level of confidence needed to allow the Company to proceed to feasibility. We will also continue to target drilling towards an increase in the current Inferred resource. Drilling to date has focused within a small area of the Tulu Kapi Licence and the planned deeper drilling will remain within this defined block. Further work will be required to test the other extensions known to occur within the immediate environs of Tulu Kapi, and there is significant potential to encounter further mineralisation outside of the small area where drilling has focused to date."

 

Further information on drilling campaign

 

All assay results were generated by certified laboratories operated by ALS-Chemex and SGS Laboratory, South Africa. Drilling, sampling, chain of custody procedures and data collection and storage have all been independently verified.

 

The drill grid area measures approximately 650 metres by 650 metres and covers the central zone of Tulu Kapi. Drill traverse lines were spaced at 80 metre intervals and drill holes were sited at distances of either 80 or 40 metres between holes along each traverse. Drill holes were inclined at angles ranging from 60 to 75 degrees in a north-easterly direction to achieve notional intersection perpendicular to the assumed dip of mineralisation.

 

RC drilling extended to an average depth of 200m and predominantly intersected Lode 1 and 2 mineralisation. The results demonstrate the continuity of mineralisation intersected at depth as it tracks closer towards surface, returning grades and widths that the Company believes demonstrate excellent potential to support a future open pit mining operation.
