FOR IMMEDIATE RELEASE
__________ MAIBELE KEEPS GROWING
DEEPEST INTERSECTION YET – OPENS UP MAIBELE
-
New zone-Hole 94 hits 12m of sulphide stringers including ~3m of massive and disseminated suphides at 400m depth testing downhole EM conductor.
-
Potential zone extends for 16km strike length and at depth
STEP OUT HOLE 94 (MADD0094) IS THE FIRST DEEP HOLE AND OPENS UP THE MAIBELE NICKEL DEPOSIT WITH AN INTERSECTION OF ~12m OF SULPHIDE STRINGERS INCLUDING ~3m OF MASSIVE & DISSEMINATED SULPHIDES. THE MINERALISATION STILL NEEDS TO BE ASSAYED TO CONFIRM THAT THE SULPHIDES CONTAIN NICKEL HOWEVER MINOR CHALCOPYRITE (Cu) IS VISIBLE IN THE CORE.
-
MAIBELE NORTH MINERALISED ZONE NOW EXTENDED TO ~900m. HOLE 94 IS 250m TO THE EAST OF THE LAST MINERALISED HOLE IN CURRENT DRILL PROGRAM.
-
MAIBELE IS OPEN AT DEPTH AND ALONG STRIKE TO THE EAST AND WEST.
-
MAIBELE POTENTIAL NOW OPEN TO REINTERPRETATION AS HOLE 94 WAS TARGETTED ON A DOWNHOLE ELECTROMAGNETIC (EM) CONDUCTOR WITH NO SURFACE EXPRESSION (NOT A VTEM ANOMALY).
-
DOWN HOLE EM NOW PLANNED TO TARGET OTHER CONDUCTORS WITH 5 HOLES SELECTED.
Botswana Metals Limited (“BML”) is pleased to advise that drilling continues to expand its Maibele North Ni, Cu & PGEs deposit with Hole MADD0094 intersecting sulphides at a true depth of 400m successfully confirming mineralisation at depth after testing a down hole EM conductor. The tenor of Ni, Cu and PGEs mineralisation in the sulphide zone will

be determined by independent laboratory analysis and released accordingly, though onsite scanning of the core using a handheld XRF analyser has indicated that elevated levels of Ni and Copper are present in the sulphide mineralised intervals.
Details are:
0.40m of disseminated sulphides from 344.0m encountered with minor chalcopyrite (copper sulphide indicator)
and
12.5m of sulphide stringers, disseminated and massive sulphides intersected from 457.18m including:
From 462.75 @ 1.25m of massive sulphides with minor chalcopyrite From 463.65 @ 0.21m of massive sulphides From 466.63 @ 0.19m of massive sulphides From 468.48 @ 0.05m of massive sulphides From 468.53 @ 1.12m of disseminated sulphides From 469.65 @ 0.08m of massive sulphides
(all widths are down hole lengths and hole 94 drill core is being prepared for laboratory assaying).
Down hole EM on Hole 94 will be used to reassess these conductors for further drilling.
Hole MADD0094 intersected the ~200m long conductor at vertical depth of 400m (~450m down hole). The target was indicated from down hole EM surveying in hole MADD0025 that showed an off hole conductor at approximately 350m vertical depth with a dip extent of ~200m. MADD0094 appears to have intersected the conductor approximately 50m below the modelled top and a further 150m remains untested below MADD0094. Above MARD0094 and MADD0025 a moderate strength TDEM conductor that models with a 200m dip extent from ~100m to ~300m vertical depth remains untested. This target has been modelled for a further 600m east of MADD0025 / MARD0094.
The Maibele North nickel-mineralised trend has now been defined over a strike length at least 2km that includes AIRSTRIP, MAIBELE NORTH & MAIBELE NEW ZONE and remains open to the east,west and at depth.
Figure 1 indicates the potential 16km anomalous zone where nickel has been intersected at Airstrip Copper, Maibele North, Maibele new intercept (hole 84) and VTEM anomaly 10830a. Within this zone several VTEM conductors (10780a, 10830a, Maibele Extension and Mashambe) require further testing.

Regional Potential
Examination of regional geological and geophysical images shows linear features that correlate strongly with the zone of mineralisation and extend a considerable distance to the east towards the Maibele North Extension prospect and further still towards the Mashambe Prospect (see Figure 1). Both of these prospects are marked by prominent VTEM anomalism and the presence of ultramafic lithology and geochemical anomalies. PL 59/2008 “Maibele Extension and Mashambe lie some 5km and 6km respectively east of the Maibele “new zone” and exhibit similar surface geological indicators to those at Maibele North that mark the presence of significant Ni + Cu + PGEs mineralisation. PL59/2008 is 100% owned by BML and not currently subject to the JV with BCL.
The same linear trend can be traced 5km to the west of Maibele North and Airstrip Copper to VTEM Anomaly 10380a, where a single historic drill hole into a conductor plate returned 0.3%Ni in sulphides down hole.
Evidence is mounting that Maibele North – Airstrip Copper lie on a regional geological horizon of at least 16km in length prospective for Ni-Cu sulphide mineralisation and containing a number of prominent conductive anomalies associated with ultramafic lithology. BML believes this trend is grossly under explored.

Botswana Chairman Mr Patrick Volpe said: “We have a significant deposit at Maibele and these are very exciting times for BML.
It is our first real deep hole and it was drilled outside a VTEM anomaly. It opens up the entire potential of Maibele which is stll open along strike to the east and to the west and at depth.
We will continue to use down hole EM as a pathfinder to locate additional deeper conductors which should save the JV a lot of expense on drilling as it will focus our deep drilling targets.
Step out Hole MADD0094 will result in the JV committing to infill drilling in 2015 to determine the extent of the mineralisation between hole 84 and to the west. The potential to the east of hole 84 is still open and we also need to explore at depth given this recent result. So many opportunities have opened up with this “MAIBELE NEW” discovery hole.
The deposit is growing as we gather more information regarding the Maibele Prospect which is shaping up to become a very significant nickel deposit. Both JV partners (BCL and BML) are very excited by this new intersection.” He said.

About BCL Limited
BCL Limited is a mining and smelting company owned by the Botswana Government. The company commenced operations in 1959 and is now one of the largest private sector employers in Botswana.
BCL Limited produces two types of finished matte containing nickel, copper and cobalt, and platinum group and precious metals to a smaller extent. The Selebi Phikwe ore deposits are owned and operated by BCL Limited.
The Selebi copper and nickel ore body was discovered in 1963, and higher grade ore was discovered at Phikwe in 1966. Mining of nickel-copper ore commenced in 1973 and since

1980, BCL’s smelter has operated at an annual production rate of approximately 50,000 tonnes of nickel-copper matte.
BCL Investments (Pty) Limited is a wholly owned subsidiary of BCL Limited.
About the BCL Limited Farm-In Joint Venture on PL 110/94, PL 111/94 and PL 54/98
BCL Investments (Pty) Limited (“BCL”), under the joint venture agreement, can spend an initial AUD$4 million on a drilling program to earn 40% of the projects over these areas. BCL has the option to continue to fund the projects to the completion of a Bankable Feasibility Study (“BFS”) to earn a 70% interest.
At that point BCL will have the off-take rights at commercial prices, to any ore mined. It is planned to truck ore to the BCL smelter operations at Selebi Phikwe for processing, which is situated 55 km to the southwest of our projects. BCL also has a first right of refusal to participate in exploration on the Company’s other prospecting licences in Botswana. The Company will retain a 30% interest after the BFS is completed, at which time the management of the projects will be transferred to BCL.
BCL Investments (Pty) Limited - Farm-in Joint Venture Agreement
BCL executed the revised Farm-In Joint Venture Agreement on 22 January 2014 with the only condition precedent being that the DOM grants extensions to PL 110/94, PL 111/94 and PL 54/98 (“the three PLs”). The DOM subsequently granted the extensions to the three PLs. The Company has made base metal discoveries within the three PLs: Maibele North (nickel, copper and platinum group elements), Airstrip Copper (copper and silver) and Dibete (copper and silver). A total of 23 VTEM base and precious metal anomalies have been identified to the east of the discoveries.
The Company believes that the agreement with BCL could substantially benefit the Company and its shareholders. The BCL group has been operating a nickel, copper and platinum group elements mine and smelter facility at Selebi Phikwe since the 1970s. Both operations are only 55 km to the southwest of the PLs. BCL has put in place a policy to find business opportunities that can extend the longevity of the mining and smelting operations located at Selebi Phikwe. BCL employs 5,000 people and the township of Selebi Phikwe has a population of 50,000.
The Joint Venture partnership can potentially fast track BML’s efforts towards commencing an operation within the three PLs. The economics of bringing these potential projects to production will be significantly enhanced by the fact that the BCL group mining and smelting facilities are already in existence and logistically close enough for ore to be trucked to the Selebi Phikwe site.
Of the three BML projects, Maibele North nickel prospect has been given priority for drilling as previous diamond drilling intercepted nickel mineralisation at around a depth of 50 m. If the economics permit, the capital and operating costs of developing a mine would be

significantly reduced due to the availability of BCL’s processing plant situated 55 km away from the joint venture exploration areas.
BCL and the Company have recently been working together to prepare an exploration plan.
APPENDIX 1 – JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| CRITERIA | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques |
- Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. - Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. - Aspects of the determination of mineralisation that are Material to the Public Report. - In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• Drill core is arranged neatly in 1m core trays for HQ (typically weathered rocks above the limit of oxidation) and 1.5m core trays for NQ core from competent rock. Core is marked at every metre along an orientation line. • Samples for independent laboratory analysis are collected at appropriate geological and or mineralization boundaries and are generally 1m or less in width. • Spot analysis using an XRF analyser has been undertaken at every 10cm interval across the sulphide mineralised intervals at the BML site office in Tshokwe using a portable XRF analyser (INNOV-X Delta Premium). Industry standards and blanks are used to monitor the calibration of the instrument. • This information is used as a guide to the potential Ni tenor of the sulphides and primarily used to determine appropriate sampling intervals for independent Laboratory analysis. |
| Drilling techniques |
- Drill type (eg core, reverse circulation ,open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face sampling bit or other type, whether core is oriented and if so, by what method, etc). |
• The holes referred to in this release have been drilled by Reverse Circulation or HQ Diamond core through the weathered rock and NQ Diamond Core through unweathered rock and the mineralized zones. • All core drilling is standard tube method. • All competent core from the current program is oriented using a spear orientation method. • Historic holes have been either NQ core, HQ core or Reverse Circulation percussion methods. |

Core (or costean, channel, etc) photography. - The total length and percentage of the relevant intersections logged. |
• All core will be photographed with beginning, ending and intermediate intervals clearly marked on each box. Core will be photographed prior to sampling or any other procedures that may disturb the initial orientation of the core. • The core will be logged in appropriate detail including identification of lithology, structure, alteration, mineralization and other notable characteristics. • Percentages of core recovery and Rock Quality Descriptor (RQD) will be included in the log. The core recovery will be calculated based on each drill run (interval). The RQD calculation will be based on the total length of core sections recovered that are greater than 2.0 times the core diameter for each drill run or interval. |
| Sub- sampling techniques and sample preparation |
- If core, whether cut or sawn and whether quarter, half or all core taken. - If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. - For all sample types, the nature, quality and appropriateness of the sample preparation technique. - Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. - Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. |
• Core is cut along the marked orientation line, half core is sampled for metallurgical test work. The remaining half core is cut for quarter core for lab assaying and storage. • No field duplicates were taken. • For lab dispatch, blanks and certified reference material are inserted at every 5th sample for QAQC. |

| Data aggregation methods |
- In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. - Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. - The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Where uneven sampling intervals have contributed to an averaged result, the result has been calculated by a weighted average technique that incorporates the interval width of each contributing sample. • A grade cut off of 0.3% and internal dilution of <2m has been used in the calculation of significant intercepts. • No grade truncations have been applied to the data. • The Maibele North ore is interpreted to be genetically and mineralogically similar to the ore treated at the nearby Selebi Phikwe smelter where current recovery grades in the flotation plant average 84% for Ni and 95% for Cu. Where Ni Eqv calculations have been undertaken on historic assay results it has been assumed that similar high recoveries will be achievable. The current drill program has been designed to assess the metallurgical properties of the Maibele North mineralisation and the indicative recoveries will be published in due course. • Given that that the Maibele North project is currently the subject of a Joint Venture with the nearby Mine and Smelter operator, BCL, BML assumes that no impediments in recovering and selling the metals contained in the deposit would exist provided an viable economic resource can be defined. |
| Relationship between mineralisation widths and intercept lengths |
- These relationships are particularly important in the reporting of Exploration Results. - If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. - If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• The precise geometry of the mineralization with respect to the drill hole angle is not known and thus, all drill hole results are reported as down hole length. • The drill holes in the current program are inclined reconnaissance holes based on the average dip of exposed units. The orientation of the mineralization is unknown and true width is unknown. • Geotechnical logging is under way to address the geometry of mineralisation. |

| CRITERIA | JORC Code Explanation | Commentary |
|---|---|---|
| Diagrams | - Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Plan view and/or cross section maps of the reported drill holes are included in this announcement. |
| Balanced reporting |
- Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• The results in this announcement are interpreted to lie within the plane of a mineralized trend that is coincident with an ultramafic intrusion and encompasses the Maibele North and Airstrip Copper Prospects. |
| Other substantive exploration data |
- Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• There is no other material exploration data that have not been previously reported. |
| Further work | - The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). - Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• The Maibele North Prospect is currently the subject of a 6000m drill program of 30 holes designed to verify previous results, obtain metallurgical samples and ultimately to facilitate the calculation of an initial JORC compliant resource for the project. • If a potentially economic resource is defined, then it is envisioned that he project will proceed to Pre-Feasibility Studies. |
