Bannerman Reports New Regional Exploration and Infill Drilling Results

PERTH, AUSTRALIA--(Marketwire - July 21, 2010) - Bannerman Resources Limited (TSX:BAN)(ASX:BMN)(NSX:BMN) ("Bannerman" or the "Company") announces encouraging new exploration and infill drilling results from its Etango Project in Namibia, southwestern Africa:

  • Numerous uranium intersections have been returned at the Ondjamba Prospect from follow-up RC drilling on the previously-announced Radon cup anomalies. Further drilling is scheduled to determine the potential for a satellite pit in this location, adjacent to the southern end of the Etango deposit.
  • Anomalous zones have been identified from a Radon cup survey at the Rössingberg Prospect, 8km to the north of Etango. Drilling programs to test the identified anomalies are now scheduled.
  • Additional high-grade intersections have been received from infill drilling at the Oshiveli area of the Etango deposit, with the intersected mineralisation expected to add to the confidence of the existing resource estimate in this area. 
  • The next Etango resource update is scheduled for the end of the September 2010 quarter.

Bannerman CEO Len Jubber said: "Drilling of highly anomalous Radon gas occurrences within the Ondjamba Prospect, only 2km east of the proposed Etango open pit, has confirmed the presence of concealed uranium mineralisation. A number of drillholes have intersected relatively shallow resource grade mineralisation within 100 metres of surface in this area. We are very pleased with this early drilling success." 

"The potential for a satellite pit at Ondjamba is exciting given the close proximity to the existing Etango deposit and the additional value it could bring to the Project."

"As well as the recent drilling success at Ondjamba, a Radon cup survey has now been completed at the Rössingberg Prospect and RC drilling is to commence shortly to test the identified anomalies."

RC Drilling on Etango South RadonX™ Anomalies

On 10 May 2010, Bannerman announced the results of a RadonX™ survey in areas within and surrounding the Etango deposit. The survey covered an area of approximately 50km2 and was successful in identifying a large number of potentially uraniferous areas indicated by anomalous radon gas measurements. The largest of these anomalies have been named "REA" to "REG" (Radon Etango A, etc). 

Bannerman commenced reverse circulation ("RC") drill testing of these anomalies in mid May. By 20 July 2010, a total of 42 RC drillholes had been completed on the anomalies. The best drilling results have been returned from the Ondjamba "REC" Anomaly, approximately 2km to the east of the proposed Etango open pit. 

The plan below shows the high Radon gas anomalies over the Etango deposit area, with the REC Anomaly drilling results labeled. The drilling results are tabulated in full in the Attachment to this release. The areas shown in pink and red reflect the highest Radon emissions while the green and blue areas have the lowest. The red dots show the completed RC drillholes. The assay results obtained to date, from the first 12 drillholes, confirm the discovery of broad mineralised zones within approximately 100 metres of surface.

Drilling is continuing in the Ondjamba REC area, following which preliminary mine optimisation work is planned to test the economic viability of a satellite open pit at Ondjamba. If deemed economic, the area will be infill drilled and incorporated into the Definitive Feasibility Study currently underway. 

Drilling on most of the other anomalies has returned thinner, lower grade mineralisation, close to the surface. To date, only seven of the identified anomalies have been drilled.

Rössingberg RadonX™ Survey Results

During June and July 2010, Bannerman extended its RadonX™ survey program to the Rössingberg Prospect area approximately 8km to the north of the Etango deposit. The survey area in this location covers approximately 70km2 and includes the Rössingberg, Ombuga and Gohare Prospect areas which comprise a 16km long zone of scattered radiometric anomalies. The area is variously covered with soil, sand, buried channels and weathered and depleted bedrock. The Rössingberg survey comprised approximately 2,800 cups on a 100m x 200m grid pattern.

The RadonX™ cup survey method is a cost-effective method for identifying the potential for uranium mineralisation down to a depth of up to 100 metres beneath desert sands and surface material. The presence of cover and depleted surface material has previously prevented detection of uranium mineralisation through field mapping or radiometric geophysics. 

The diagrams below show the Etango licence area on the left and the Radon survey results on the right, with the areas coloured pink and red reflecting the higher tenor Radon survey anomalies. The previously-reported Radon survey contours for the Etango area are also shown for reference.

To view the second graphic associated with this press release, visit the following link:

It is notable that the Rössingberg Radon anomalies lie in two main trend lines running northeast to southwest, roughly coincident with the previously identified radiometric anomalies. There are high tenor Radon anomalies in numerous areas which have never been drill tested.

The Rössingberg trend represents a large mineralised system up to 16km long, with the potential for an undiscovered major deposit. The best anomalism appears to lie in the centre of the Rössingberg survey area, in a location with minimal radiometric anomalism. A drilling program is scheduled to test the identified Radon anomalies at Rössingberg.

Oshiveli Diamond Drilling Results

Recent diamond drilling at Oshiveli in the northern part of the Etango deposit has targeted conversion of known Inferred Resource material to Indicated and Measured Resource categories, and has also sought to confirm interpreted extensions of the known mineralisation.

Favourable shallow and above average grade intersections from a further 12 infill diamond drillholes at Oshiveli (full results listed in the Attachment) continue to support the geological interpretation and grade assessments in the area. The addition of the intersected mineralisation is expected to enhance the confidence (i.e. classification) of the existing resource estimate in this location.

Exploration Programs

Bannerman is now actively engaged in regional exploration in Namibia and Botswana. All of Bannerman's exploration properties lie in close proximity to known uranium mines, deposits and anomalies including Rössing, Langer Heinrich and others in Namibia and Letlhakane and Foley in Botswana. 

The exploration work underway now includes ground-based geological mapping, Radon cup surveys, ground radiometric surveys and electromagnetic geophysical surveys. In the past, exploration in these areas was based on the concept of discovering uranium mineralisation by radiometric surveys, either airborne or on the ground, and the programs now underway will complement this work by better testing areas of cover and surface depleted rocks which were not amenable to radiometric surveys.

Work has also been completed on ground based geophysical surveys at Etango and Swakop River. These results will be further assessed and will be used for future drill targeting. Work is also now underway on access and planning for a RadonX™ survey on the Botswana tenements, due to commence in the near future.
