TULU KAPI PROJECT

Mining Licence Application

On 13 May 2011 an application for a Large‐Scale Mining Licence was lodged with the Ethiopian Government in relation to the Company's flagship Tulu Kapi gold project in Western Ethiopia. The application included technical, social, environmental, legal and financial components drawn together by Nyota and its consultants, including the outcomes of the Preliminary Economic Assessment announced on 3 March 2011.

The new resource estimate announced on 29 July 2011 led to the proposed mine plan and financial model being updated. These were submitted to the Government at the start of October.

Nyota's application is believed to be the first application for a Large‐Scale Mining Licence under the new Mining Proclamation, which was promulgated in August 2010, and Tulu Kapi will be the first new gold mine to be developed by way of private foreign investment in recent times. Whilst beneficial to the region as a whole, this inevitably introduces challenges for all parties concerned. Notwithstanding this, the application is being processed and assessed in a timely fashion and meetings with Government officials in Addis Ababa after the end of the reporting period, following submission of the new mine plan, have led to good progress.

Tulu Kapi Resource

A new JORC‐compliant Mineral Resource for the Tulu Kapi ore body was announced on 29 July.

Undertaken by independent consultant Wardell Armstrong International, this comprised a total of 15.96 million tonnes @ 2.84g/t gold containing 1,460,000 ounces of gold; of which 1,003,000 ounces are in the Inferred Resource category at an average grade of 2.76g/t.

The diluted resource, taking account of potential mining selectivity, contains 1.25 million ounces of gold at an average grade of 1.98g/t.

Modelling of the Tulu Kapi ore body identified a number of areas within the current boundary and proximal to it where there is an obvious need for further drilling and where the possibility exists to add gold ounces and further improve the economics of the project.

This drilling is on-going and a further resource update is provisionally scheduled for January 2012.

In addition, the rainy season has been utilized to re-assess the very large amount of geological information gathered over the previous nine months. This work is ongoing but indicates that a new structural model may explain the previous difficulties in linking geological sections together. Testing of the this model is-ongoing, but if successful is likely to significantly reduce the additional drilling required to increase the confidence level of the Resource (i.e. upgrade Inferred resources to Indicated) and make it more likely that additional ounces will be added to the overall Mineral Resource.

Definitive Feasibility Study

In September, Nyota appointed of the lead engineer and other key consultants for the Definitive Feasibility Study for the Tulu Kapi Gold Project.

SENET (Pty) Limited ("SENET") has been appointed as Lead Engineer, Golder Associates ("Golder") has been appointed to undertake the Environmental & Social Impact Assessment ("ESIA") and to design the tailings storage facility, and Wardell Armstrong International ("WAI") has been appointed to manage resource estimation and mine design/planning.

The DFS is provisionally scheduled for completion by Q3 2012 and is targeting an accuracy within +/-10%. Mine and processing plant design will be based on a standard 2 million tonne per annum ("mtpa") gold plant, a format frequently built in Africa and ideally suited to the environment anticipated in Ethiopia.

Drilling Activities

During the quarter, diamond drilling totalled 7,440 meters for the purpose of infill as well as extension of the existing ore-body. 

This was below the budgeted metreage for the period as the drilling rate and site access were negatively impacted by heavy rain. The opportunity was therefore taken to carry out maintenance, for staff to take annual leave and for the geologists to re-appraise, and where appropriate, to catch up with the large amount of data collected in the previous nine months.

Reverse circulation drilling for the hydro-geology program totalled 2,816 meters. Sampling of these dual purpose holes added additional grade intersections to the Tulu Kapi resource. Reverse circulation drilling of the deposit was not possible due to the heavy rains during the wet season.

The drilling programme during the quarter continued to focus on extending the high-grade Feeder Zone resource, testing the S.E. and N. Extensions to Tulu Kapi, and extending preliminary drilling of the UNDP Target.

The first set of results was announced on 23 August:

Tulu Kapi Feeder Zone

·; New Feeder Zone high-grade gold intersections over notable widths including peak intersections of 23.30g/t Au over 1.20m, 14.50g/t Au over 8.00m, 7.30g/t Au over 14.40m and 5.42g/t Au over 26.55m;

·; Intercepts provide valuable additional infill data for the Feeder Zone geological model;

·; Updated geological model being used to refine preliminary underground mine design.

 

Tulu Kapi Infill Drilling

·; Drill results for infill holes within the main Tulu Kapi body aimed at upgrading the resource including peak assays of 26.02g/t Au over 2.85m, 25.01g/t Au over 3.0m, 15.63g/t Au over 3.0m, 13.81g/t Au over 15.67m and 13.66g/t Au over 8.35m;

·; Completion of a number of geotechnical holes drilled to provide data for future detailed pit slope design also intersected further mineralisation.

N. Extension

·; High grades and substantial widths achieved from drilling of the Northern Extension to Tulu Kapi with peak grades including 22.50g/t Au over 2.0m, 21.81g/t Au over 5.45m and 3.50g/t Au over 10.8m.

S.E. Extension

·; Notable shallow high-grade intersections achieved over the S.E. Extension with peaks grades including 4.71g/t Au over 4.0m, 4.32g/t Au over 18.0m, 4.14g/t Au over 6.0m and 2.02g/t Au over 27.0m.

UNDP Target

·; Further evidence of the extent of mineralisation on the periphery of the UNDP Target with peak grades including 5.75g/t Au over 1.0m, 2.69g/t Au over 7.0m and 0.47g/t Au over 20.0m.

 

PROXIMAL AND SATELLITE TARGETS

A substantial number of Proximal and Satellite targets exist in the Tulu Kapi region. Not all of these will be converted to resources and at present there is a variable combination of drilling, trenching and soil geochemistry; geophysics are variously being conducted over all of the proposed targets.

During the quarter very limited fieldwork was undertaken and almost no drilling was possible due to the rainy season. 

Exploratory drilling at Chalti was halted due to poor ground conditions during the wet season. The initial three diamond holes show gold associated with base metal sulphide as reported in the last quarterly report. Following analysis of the geological dataset it has been decided that prior to further drilling Nyota will undertake a ground-based geophysical survey (magnetometer/Induced Polarization methods). 

On the Guji Prospect a total of 19 diamond drillholes have been completed since 2007. Holes have been drilled over both gold in soil geochemical anomalies and geophysical targets, with two styles of gold mineralisation being identified. Firstly, near-surface saprolite mineralisation, which Nyota will prioritise, and secondly, gold associated with both sulphides and quartz veins in fresh rock.

Of the two, the saprolite target warrants earlier further investigation, with peak grades intersected of 21.1g/t Au over 1.0m, 9.85g/t Au over 0.90m, 6.38g/t Au over 0.70m and 3.07g/t Au over 1.10m and a trench assays of 9.60g/t Au over 68.5m.

The drilling planned for Guji requires the use of the reverse circulation rig to drill a grid of close spaced, vertical short holes only as deep as the bottom of the saprolite (approximately 30 meters). This work will be undertaken during the next two quarters with a view to including the results in the evaluation of the Tulu Kapi project envelope. (Note: The target falls outside of the Tulu Kapi Mining License application and will therefore require a standalone DFS).

 

REGIONAL ETHIOPIAN GOLD EXPLORATION

The initial interpretation of the airborne magnetic survey completed over the Northern Blocks as announced on 18 May 2011, and identified a total of 47 targets of merit. Prior to the commencement of the rainy season, seven initial targets were followed‐up on the ground by mapping and sampling, including the Boka Sirba, Tsole Mole and Bendokoro targets.

All of the results from this follow up work have now been received and analysed and Nyota considers the above named three targets to be "drill ready". A multi‐purpose drill rig has been allocated to them and will be delivered to site when the new field camp is opened and access has been improved.

From these three targets the following results were announced shortly after the end of the quarter (12th October, 2011):

 

 Two new discoveries at the Bendokoro North Prospect

·; The East anomaly comprises an 800m long, 100m wide target and has returned gossan grab samples with peak grades of 10.6g/t Au, 8.89g/t Au, 8.81g/t Au, 5.67g/t Au, 4.29g/t Au and 3.18g/t Au and coincidental base metal anomalism;

·; The West anomaly extends over a 1km strike length, is 100 to 200m wide and includes continuous gold in soil geochemical results peaking at 1.39g/t Au; and

·; Both East and West anomalies are open‐ended to the north, south, east and west.

 

New discovery within the Boka Sirba Prospect

·; Total number of Boka targets now 3 with a total combined strike length exceeding 15km;

·; Additional rock chip sample results for the original Boka Sirba Target include peaks of 5.92g/t Au and 5.85g/t Au complementing an earlier peak sample grade of 10.85g/t Au; and

·; Boka‐Sirba West, the latest target, shows high Cu, Zn and Ag values associated with grab samples returning peak Au grades of 16.06g/t and 8.84g/t.

Reconnaissance exploration will continue through to June, 2012 (the approximate start of the next rainy season) on the balance of 40 targets. This work will include stream sediment, rock chip, heavy mineral concentrate sampling and trenching; the same techniques that have successfully delineated the current suite of targets being evaluated.

MUREMERA NICKEL PROJECT

During the reporting period Nyota applied for the renewal of the Muremera license based on expenditure and work completed to date. At the reporting date Ministerial confirmation is pending.

CORPORATE

Environmental and Social studies

In addition to the Environmental and Social Impact Assessment that was submitted as part of the Mining Licence Application, on-going environmental baseline studies and detailed environmental and permitting work will continue in parallel with exploration programs and in support of the definitive feasibility study. Discussions with Government and a series of community briefings and consultations with local stakeholders are also continuing.

Golder Associates was selected to lead these studies and Synergy Global Consulting was selected to lead the preparation of the resettlement action plan. Both groups are required to deliver their studies consistent with international best practice including the International Finance Corporation's Performance Standards.

Health and Safety

Nyota recognizes that the health and safety of its personnel is fundamental to the success of its operations. During the last quarter, no lost time injuries were recorded on the Tulu Kapi Project.
