Sampling Technique

Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information.

The Mankarga area has been drilled by auger techniques. The drill spacing is being in-filled to a nominal 200m x 50m grid spacing on northwest-southeast lines. Samples are taken from a 3m composite at the end of hole.  Hole depths range from 1 to 11m vertical depth.

Samples were despatched to BIGS in Ouagadougou for sample preparation, where they were crushed and dried to produce a sub sample for 0.5kg bottle roll analysis with AAS finish. 

Drilling

Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. 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.).

Auger drilling was completed for geochemical samples.  Holes were vertical and drilled between 1m and 11m, with an average of 5.5m.

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.

Sample recoveries are not applicable to auger drilling.  Samples are only used for exploration purposes and are not used in resource estimation.

Logging

Whether core and chip samples have been geologically and geotechnical 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/Trench, channel, etc.) photography.
The total length and percentage of the relevant intersections logged.

Logging of auger chips are recorded lithology, mineralogy, mineralisation, weathering, alteration, colour and other features of the samples.

Sub-Sampling Technique 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.
Whether sample sizes are appropriate to the grain size of the material being sampled.

Auger samples were collected on the rig using a scoop. All samples were dry.
The sample preparation for all samples follows industry best practice. BIGS in Ouagadougou for sample preparation, where they were crushed and dried sub sample for analysis.
Field QC procedures involve the use of certified reference material as assay standards and blanks. The insertion rate of these averaged 1:20.
 

Quality of Assay Data and Laboratory Tests

The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.

The laboratory used a bottle roll for with an AAS finish for gold analysis.
No geophysical tools were used to determine any element concentrations used in this report.
Laboratory QA/QC involves the use of internal lab standards using certified reference material, blanks, splits and duplicates as part of the in house procedures.
Certified reference materials, having a good range of values, were inserted blindly and randomly. Results highlight that sample assay values are accurate and that contamination has been contained.
Repeat or duplicate analysis for samples shows that the precision of samples is within acceptable limits.
Sample preparation conducted and fire assay performed by BIGS SARL.

Verification of Sampling and Assaying

The verification of significant intersections by either independent or alternative company personnel.
The use of twinned holes The verification of significant
intersections by either independent or alternative company personnel.
Discuss any adjustment to assay data

WAF’s QP R. Hyde has verified significant results from auger drilling.

Primary data was collected using a set of company standard   ExcelTM templates on ToughbookTM laptop computers using lookup codes.  The information was validated on-site by the Company’s database technicians and then merged and validated into a final Access TM database by the company’s database manager.

Location of Data points

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
Specification of the grid system used Quality and adequacy of topographic control

All drill holes have been located by DGPS in UTM grid WGS84 Z30N.
No dh surveys are take for auger drilling.
DGPS was used for topographic control.

Data Spacing and Distribution

Data spacing for reporting of Exploration Results
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
Whether sample compositing has been applied

The nominal drill hole spacing is 50m (northwest) by 200m (northeast) which is appropriate for exploration purposes.

Orientation of Data in Relation to Geological Structure

Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

Not relevant.

Sample Security

The measures taken to ensure sample security

Chain of custody is managed by WAF
Samples are stored on site and delivered by WAF personnel to BIGS Ouagadougou for sample preparation.
Whilst in storage, they are kept under guard in a locked yard. Tracking sheets are used track the progress of batches of samples

Audits or reviews

The results of any audits or reviews of sampling techniques and data.

WAF personnel and consultants have completed numerous site visits and data reviews since acquiring the project in 2014. No material issues were noted.  A technical reports are located on WAF's website.

Mineral Tenement and Land Tenure Status

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.

The Boulsa Project tenements covers over 3,700km2, granting the holders the right to explore for gold.
The tenements have been acquired by either direct grant to WAF or its subsidiaries or by contractual agreements with tenement holders. Apart from the Tanlouka Agreement where Tanlouka SARL holds a 90% interest, all other vendor agreements provide WAF with the right to obtain an ultimate interest of 100%.
All licences, permits and claims are granted for gold.  All fees have been paid, and the permits are valid and up to date with the Burkinabe authorities.
The payment of gross production royalties are provided for by the Mining Code and the amount of royalty to be paid for ranges from 3% (<US$1000), 4% ($1000-1300) and 5% (>$1300).

Exploration Done by Other Parties

Acknowledgment and appraisal of exploration by other parties.

Very little exploration has been carried out over greater project the tenement prior to WAF's involvement which commenced in 2008, with the exception of the Tanlouka Permit.  The area comprising the Tanlouka Permit has been held by Channel Resources Ltd since the early 1990's.  Work recommenced in earnest on the Tanlouka Permit in 2010.  WAF acquired Channel Resources Ltd on January 17th 2014.  Available historic records and data were reviewed by both WAF during Due Diligence prior to the acquisition.

Geology 

Deposit type, geological setting and style of mineralisation.

The Boulsa Project straddles some 70km strike length of the Manga-Sebba greenstone belt, which bifurcates and trends northeast and east-northeast respectively from southern-central Burkina Faso into Niger over some 450km. The south-eastern portion of the project area covers the southern extension of the Fada N’Gourma Belt.

Lithologies comprise volcano-plutonic bodies including amphibolised basalts with amphiboloschists, andesites and basalts, rhyolites and rhyodacites, brecciated tuffs, and gabbroic bodies including pyroxenite and serpentinite. Gold mineralisation in the project area is mesothermal orogenic in origin and structurally controlled. The project also contains shear hosted porphyry related copper-gold-molybdenum mineralisation on the Sartenga Permit which is believed to be unique in West Africa."

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:

• easting and northing of the drill hole collar
• elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
• dip and azimuth of the hole
• down hole length and interception depth
• 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.

Not relevant for auger drilling as holes are generally very short and give an indication of mineralisation at depth and will be followed-up with RC and diamond drilling in due course.  None of the information in this release will be used to compile a Mineral Resource.

Data aggregation methods 

In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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.

All samples represent a 3m end of hole composite, where possible.

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 (e.g. ‘down hole length, true width not known’).

The orientation of the mineralised zone has been inferred from geophysical and geological interpretation.

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.

The appropriate plans and sections have been included in the body of this document.

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.

Not applicable to reporting of auger results.

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.

Preliminary metallurgical test work has been completed, with excellent results. Gold recoveries exceed 95% from oxide bottle roll tests, exceed 92% for sulphide bottle roll tests and a significant proportion of the gold is recoverable by gravity concentration. Additional metallurgical test work is being completed.

Further work 

The nature and scale of planned further work (e.g. 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.

Follow-up drilling is planned and is ongoing, aimed at defining the source of the anomalies discussed in this report. A figure showing proposed work programs is included in the body of this report.
