About Botswana Metals
The drill rig has been operating for the past week and has completed over 450m across 8 of the planned 22-hole program. Most of the holes have intersected significant widths of visible supergene copper mineralisation at shallow depths.
HIGHLIGHTS
-
Hole DBRC123: 17m of strong malachite-azurite mineralisation from 15m.
-
Hole DBRC124: 23m of strong malachite-azurite mineralisation from 24m.
-
Hole DBRC126: 5m of strong malachite mineralisation from 22m.
-
Hole DBRC128: 6m of strong malachite mineralisation from 24m.
Botswana Metals is exploring for nickel, copper, cobalt, tantalum and lithium within its ~1,500 square kilometre exploration portfolio. These “new world” metals are becoming increasingly important as the world switches to cleaner sources of energy.
The company announced a maiden JORC Inferred Resource of 2.38Mt on 28[th] April 2015 from drilling within a small 185 square kilometre section of its exploration portfolio in which it had entered a joint venture with BCL. At the time cobalt was not included in the resource calculation.
Historical drilling outside of the joint venture ground has intercepted further nickel as well as significant intercepts of copper and cobalt.
A soil sampling program detected traces of lithium and tantalum which warrant further exploration.
Large tracts of BML’s exploration portfolio remain unexplored.
-
Hole DBRC129: 12m of strong malachite-azurite-chalcocite mineralisation from 37m.
-
Hole DBRC130: 13m of strong malachite-azurite-chalcocite mineralisation from 41m.
Samples from the first week of drilling are currently being sent to an independent laboratory in South Africa for analysis. Results will be released to the market as soon as they are received.
DRILL PROGRAM
The 1500m RC drilling program has been designed to test new mineralisation models at both the Dibete and Airstrip Copper – Silver projects. Approximately 1000m at Dibete and 500m at Airstrip will be completed. The program will comprise twin, scissor and close-spaced infill drilling to replicate a number previous intersections and to test gaps and extensions to the current mineralisation models.
The new information generated by the drilling will provide a framework for further geological interpretation that will guide future regional and deeper exploration programs.

APPENDIX 1 – JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
| 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 n o d u l e s ) may warrant disclosure of detailed information. |
For Reverse Circulation holes, samples are collected for every m drilled via a riffle splitter attached to the cyclone. Samples are labeled and set aside to await determination for assay after onsite handheld XRF analysis is undertaken Where appropriate, 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 is been undertaken at every 10cm interval across the mineralised intervals for core, and at several sites per sample bag for RC at t h e BML site office in Tshokwe using a portable XRF analyzer (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 mineralised intervals 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 |

| Drill sample recovery |
- Method of recording and assessing core and chip sample recoveries and results assessed. - Measures taken to maximise sample recovery and ensure representative nature of the samples. - Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
For RC, sample recovery is estimated based on the amount of material returned for each m within the sample bag. If recovery is lost or inadequate, the hole will be redrilled to achieve the target The core is measured after every run, and the results are compared to the actual run to calculate core recoveries. Core is handled with care to avoid breakage and crumbling. Core is washed and laid onto holding core trays. HQ core is used on friable ground, rotation speeds and water pressure are monitored to avoid destroying the core. A soft rubber mallet is used to drive out core from the barrel. No significant core loss or recovery issues have been recorded in the current drill program. |
| Logging | - Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. - Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. - The total length and percentage of the relevant intersections logged. |
A sub-sample from each RC m is collected and logged both dry and wet as the hole is being drilled. This sub-sample is then stored in appropriated m marked chip trays and stored onsite for future reference. 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 or chips 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. |

| Geology | - Deposit type, geological setting and style of mineralisation. |
The Dibete and Airstrip projects are hosted within the Magogaphate Shear Zone - a major geological structural feature, generally considered to mark the boundary between the Archaean aged (>2.5 billion year old) Zimbabwean Craton and the Limpopo Belt or Limpopo Mobile Zone (LMZ). The nickel-copper deposits of Selebi Phikwe lie within the northern part of the Central Zone of the Limpopo Mobile Belt, whilst the nickel copper deposits of Phoenix, Selkirk and Tekwane lie in the Zimbabwean Craton. The Central Zone of the LMZ comprises variably deformed banded gneisses and granitic gneisses, infolded amphibolites and ultramafic intrusions that that have the potential to host Ni-Cu sulphide mineralization. Ni-Cu-PGE mineralization at Maibele North and Airstrip copper is spatially associated with an ultramafic intrusion. |
| Drill hole Information |
- A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all material drill holes: o easting and northing of the drillhole collar o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interceptiondepth o hole length.- If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
All drilling in this release has previously been released publicly with all relevant drill hole information already in the public domain. |
| 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%Ni or Cu and internal dilution of <2m has been used in the calculation of significant intercepts. For the >900ppm Co intervals, a grade cut-off of 900ppm Co and internal dilution of <2m has been used in the calculation of significant Cobalt intercepts. No grade truncations have been applied to the data. |
