Positive Phase 1 Drilling Results From The Imweru Gold Project

Kibo Mining plc ("Kibo" or the "Company") (AIM: KIBO; JSE AltX: KBO) the mineral exploration and development company focused on gold, nickel, coal and uranium projects in Tanzania is pleased to announce that it has now received all Phase 1 drilling results from its Imweru project, located in the Lake Victoria Goldfields of northern Tanzania.The drill programme which was completed in late November 2013, comprised 21 drill holes for a combined total of 3,265 m of reverse circulation (RC) and diamond drilling (DD).

· Gold mineralisation was intersected in 19 of the 21 holes drilled.

· Best intersections include:

ü 2.08 metres @ 11.37 g/t Au (Hole IDD001)

ü 7.00 metres @ 1.68 g/t Au (Hole IDD002)

ü 8.86 metres @ 1.70 g/t Au (Hole IDD002)

ü 4.56 metres @ 1.93 g/t Au (Hole IDD002)

ü 4.75 metres @ 3.25 g/t Au (Hole IDD003)

ü 7.00 metres @ 3.69 g/t Au (Hole IRC022)

o Including 2.00 metres @ 8.20 g/t Au

ü 3 metres @ 9.02 g/t Au (Hole IRC023)

ü 18 metres @ 1.67 g/t Au (Hole IRC023)

o Including 5.00 metres @ 4.90 g/t Au

ü 6 metres @ 2.14 g/t Au (Hole IRC026)

ü 5 metres @ 1.57 g/t Au (Hole IRC027)

ü 4 metres @ 3.09g/t Au (Hole IRC027)

· New mineralised zones were intersected which have not been incorporated in the previous resource estimate and should contribute to an increase in the updated resource estimate

· Mineralisation remains open down dip and along strike

· The Company is now awaiting completion of an independent update of the existing resource statement, prior to carrying out a Phase 2 drill programme.

Louis Coetzee, C.E.O. of Kibo commented:

"The drill results from Imweru exceed our expectations and confirm not just the continuation of the Imweru mineralised zones between previously drilled locations but new mineralised zones at depth. These results improved our confidence levels in the potential to significantly increase both the quality and quantity of the current resource on the project. We now look forward to producing an updated JORC-compliant resource estimate before proceeding to the next development phase of the project"

Table 1 below presents drill hole details and a summary of mineralised intersections.

 Drill Hole Intersection Summary Table

*Down hole interval widths have not been interpreted as true widths and further detailed modelling and interpretation of the drill results will be required to establish in more detail the geometry of the mineralised shear zone.

**A lower cut-off grade of 0.5 g/t has been used in presenting the mineralised intervals. Internal dilution within reported intervals does not exceed core lengths of 3m @ 0.1 g/t. Gold sample values exceeding 20 g/t have been cut to 20 g/t in calculating the mineralised intervals and the uncut single sample gold grades are shown in the comments column where applicable. All gold values shown are the weighted average for the respective intersections and are rounded to two decimal places.

Technical Notes 

Details of Drilling

A programme of reverse circulation ("RC") and core ("DD") drilling comprising 21 holes ( 3 DD and 18 RC) totalling 3,265 metres was undertaken to infill drill and test the depth continuation of the previously drilled Imweru Central Mineralised Zone ("ICMZ") on Kibo's Imweru project located approximately 35 km west of the town of Geita in northern Tanzania. The ICMZ forms part of a larger mineralised corridor on the project extending over 10 km along strike for which an existing NI 43-101 compliant Inferred gold resource of 629,000 gold ounces has been estimated from drilling by previous operators (refer resource statement below).

The recent drilling was completed over a strike length of 2.3 kilometres with holes angled at 55 to 60 degrees to the north or south and drilled to down hole depths of between 80 and 250 metres. The three holes (IDD001 to IDD003) were collared as RC holes within the weathered horizon but changed to DD holes from their intersection of fresh rock at depths of 98.9 metres,78 metres and 90 metres respectively to their final depths of 250 downhole metres. The drill programme was designed to provide in-fill drilling along the strike of the ICMZ as well as targeting deeper mineralisation to previously identified intersections (>150 downhole metres). Table 1 above presents final drill hole details and results. A lower cut of grade 0.3 g/t Au and a higher cut-off grade of 20 g/t Au was used in compiling the mineralised intersections shown on Table 1 and gold values are rounded to two decimal places. A map showing the drill hole locations and representative cross sections can be found on the Company's website at http://kibomining.com. The results of the exploration campaign will be used to produce an updated geological model and mineral resource estimate that is currently underway.

Discussion of Results

The drilling results exceed company expectations and demonstrated both the on-strike continuity of the ICMZ modelled from previous drilling programmes and the existence of new mineralised zones. The infill drilling has resulted in drill hole spacing of approximately 50m along the strike of the mineralisation which should provide for a more robust and improved resource estimate to be produced.

The results from holes IRC016 to 018, 020 to 021 and DD hole IDD001 in the western part of the ICMZ show mineralised intersections consistent with widths, grades and down hole locations encountered in previously drilled neighbouring holes confirming the continuity of gold mineralisation in the western part of the ICMZ. Significantly the drilling results in these holes indicate some new mineralised zones not previously intersected the best of which is the 3 metres @ 1.63 g/t Au from 142 metres to 145 metres in IRC 017. Additional narrower previously undetected gold mineralised zones are also indicated from the results both to the north and south of the currently modelled extent of the ICMZ.

The results from holes IRC019, 022-025 and DD hole IDD002 further along strike to the east confirm and extend the mineralisation encountered from previous drilling and suggest mineralised zones to be dipping to the south at both shallow angles of about 45 degrees and sub-vertically. The higher grade and width intersections in IRC023 are particularly noteworthy (3 metres @ 9.02 g/t Au and 18 metres @ 1.67 g/t Au). These intersections contain 1 m high grade samples assaying 211 g/t Au and 46.20 g/t Au which have been cut to 20 g/t Au to give the more conservative intersection grade as shown in Table 1). A comparison of holes IRC019 and IRC022 shows that IRC019 may not have been drilled sufficiently deep to intersect mineralised zones at >100 metres down hole depth subsequently drilled in IRC022. The possibility of some shallower dipping mineralised zones may have positive implications for an open-pit mine design should the company determine the project has merit to proceed to preliminary economic studies.

The results from holes IRC026 to 029 and DD hole ID003 in the central part of the ICMZ confirm that the mineralised zones dip steeply to the north along this section. The drill results taken together confirm a broad mineralised envelope between down hole depths of approximately 30 metres to150 metres containing scattered 1 to 6 metre higher grade zones of 0.5 to 3 g/t Au. Best higher grade intersections include 6 m @ 2.14 g/t in IRC026, 4 m @ 3.09 g/t in IRC027 and 4.75 m at 3.25 g/t in IDD003. The results from holes IRC030 to 033 in the eastern part of the ICMZ also confirm narrow mineralised intervals of mostly 1 m in width with grades in the range 0.5 to 2 g/t Au. similar to that encountered in previous drilling. These narrow intersections confirm continuity of the mineralised gold envelope which remains open-ended to the east.

The mineralised intersections within all the holes are within variably oxidised granododiorite and diorite which is strongly foliated and sheared with weak to moderate disseminated pyrite and trace chalcopyrite. Other alteration includes chlorite, sericite, carbonate and quartz vein stockwork and silica flooding the former becoming more intensive in association with the gold mineralised zones. Preliminary interpretation suggests that the gold mineralisation is carried in quartz veins and quartz vein stockworks while the overall geometries of the mineralised stockworks is controlled by moderate to steeply dipping shears and faults showing variable orientations to both the north and south across the mineralised zone. Work is on-going in modelling the mineralisation in 3D to better understand the detailed geometry of the mineralised zones and controls on mineralisation in order to plan the next drilling phase.

The Company is now integrating these recent results with those from previous drilling to produce an updated resource estimate to JORC standard and to determine the most appropriate next phase of development for the Imweru project planned for the first half of 2014. It should be noted that the ICMZ represents only 2.5 km of the potential 10 km strike length of gold mineralised geology on the project.

Sampling, Analyses and Quality ControlProcedures

The drilling was undertaken by Layne Drilling from Mwanzaand supervised by the Company's Tanzanian exploration staff 

under the directionof Mzuri Exploration Services Exploration Manager Graham Norton and project geologist Smith Jordan.

RC drill samples were collected at 1 metre down-hole intervals from surface. Each 1 metre RC sample was weighed, homogenised and sub-sampled on-site by riffle splitting to produce approximately a 1.5 kilogram sample for laboratory submission. DD core was removed from site under strict Company supervision to the nearby project camp site. DD core was halved by electric diamond saw with one core half submitted for analyses and the other half left in the core box for reference. DD sample intervals were a nominal 1 metre but varied in some instances at the core logging geologist's discretion. Standards, duplicates and blanks were inserted in all sampling stream in compliance with the Company's quality control procedures. Samples were dispatched to the ALS Chemex ("ALS") preparatory laboratory in Mwanza under the Company's chain of custody procedure by Company personnel. Field sample rejects (RC) and drill core are stored in a locked container at the Company's field camp under security guard protection.

The drill samples for analyses were dried, weighed, sieved/jaw crushed, riffle split and pulverised at ALS facility to produce a 50 g sub-sample for fire assay analyses and 1 gram for multi-element analyses. Sub-samples were dispatched to ALS laboratory in Johannesburg where the analyses was carried out. Laboratory standards, duplicates and blanks are analysed with each sample batch analysed in accordance with the laboratory's quality control procedures. On-going monitoring of quality control samples and a review of the final quality control report for the drilling found no discrepancies.
