JORC COMPLIANT COAL RESOURCE AT FOLEY
A‐Cap Resources Limited ("A‐Cap" or the "Company") is pleased to announce a maiden JORC compliant coal resource at its Foley prospect. Recent drilling has now successfully defined a resource within a portion of this field of 148 million tonnes of coal (total tonnes in situ (TTIS)).
Highlights of the resource estimate include:
A coal resource of 148 million tonnes TTIS estimated in accordance with the JORC Code
66.6 million tonnes TTIS in the SS Seam1 at an average yield of 78.25% to meet current specifications used for power elsewhere in Southern Africa
Shallow deposit with maximum seam depth of 57m
Total Indicated TTIS Resource of 71 million tonnes of which 29.9 million tonnes is in the SS Seam
Coal suitable for feed without beneficiation for specifically designed domestic power station.
Drilling targeted a small area of the prospective area indicating the potential for resource growth in line with expanding infrastructure
Coal is within close proximity to road, rail and power with no settlements within the resource area
Further evaluation work on the resource and potential reserves and its quality and development options are progressing with Sedgman South Africa
A‐Cap's CEO Paul Thomson stated "A‐Cap's focus was to fast track this deposit to mining studies, by drilling out a small portion or the prospective area to identify at least 25 million tonnes of Indicated Resource. This recently completed drilling program has achieved the targeted tonnages and added significant value to the Foley prospect. The quantum of the Indicated coal Resource is enough to support an initial mine life for both an export scenario at one million tonnes per annum and a supply source for a coal‐fired power station. Current infrastructure constraints in Botswana will allow one to two million tonnes per annum projects to come on line in the short term, if the commodity price is right. Later as the infrastructure capacity in Botswana grows, the coal resource on our tenements still has the potential to grow with it as we still retain significant exploration potential".
1Seam nomenclature adopted from African Energy Resources' (ASX: AFR) resource announcements to avoid duplication of naming.

Resource Description
In May this year the Bolau Coal Study, which encompassed the Bolau
nd Foley pr ospects, was completed
by Sedgman South Africa. This study was commissioned to assess the potential for development of the Bolau Coal Project covering geology, engineering and marketing. The study was pos itive and highlighted the project's potential and recommended further drilling and analyses.
The recently completed drilling campaigns at Bolau followed this recommendation, focusing on defining an Indicated Resource on the basal seam of the shallow up dip extension of African Energy Resources' (AFR) Sese Coal deposit ('Sese'), known as Foley, and the down dip extension of the Sese deposit, known as Bolau (Figure 1).

The density of drilling over the entire tenement area is insufficient to calculate a gl obal resource and initial resource definition efforts have focussed on Foley (Figure 2). All of the seven ne w drill holes in this area
intersected the coal sequence hosting the Sese Main Seam, which is made up
of the basal SS Seam,
followed by the SST Seam and finally the SSU Seam, totalling a package of approxi mately 20m thick (Figure
3). The seams are almost horizontal with a gentle dip (
3).

All of the drill holes were geophysically logged and the coal seams were modelled in order to estimate resource tonnages. In Situ Coal Tonnes at Foley total 148 million tonnes (Table 1), of which 71 million tonnes is classified as Indicated (Table 3). The resource drilling covers a small percentage of the tenement area allowing for potential upside to the current declared resource tonnage.

Once beneficiated, the quality of the coal improves to a potential export product, with increased Calorific Value ('CV'), lower Total Sulphur ('TS') and a promising yield. The yields averaged in Table 3 for the SS seam from the individual drill holes range from 66.8% to 85.7% at a 1.70 float fraction.

While A‐Cap is approaching development of its coal assets within existing transport capacity, the projects have potential to scale‐up as further transport infrastructure is established. Holes drilled during uranium exploration in 2011, at a distance of approximately 6km to the east of Foley intersected a similar coal‐ bearing sequence. This area is immediately north of AFR's 'Block C' measured resource. The Botswana Government has been proactive in paving the way for future infrastructure upgrades in the short term to Richards Bay and has recently signed the Trans Kalahari Railway (TKR) agreement with Namibia to deliver a dedicated high volume rail to Walvis Bay, with feasibility studies currently underway. The government and industry are also proactively engaging the Mozambique and Republic of South Africa rail entities regarding further increases in capacity.

Summary
A‐Cap has successfully delineated an Indicated Coal Resource in order to fast track this project towards development. The resource size is now at a critical tonnage to allow a meaningful mine life to be considered. The resource is considered to be thermal coal with potential for a local power station project and export quality for consumption in the Southern Africa region and also to the seaborne coal market.
A‐Cap is progressing the studies with Sedgman South Africa to look at potential mining studies and markets within the bounds of forecast coal prices.

Geology
|
Foley is located in the east of the Kalahari Basin that stretches from south‐west to north‐east across Botswana.
|
|
Geology
|
The coal package occurs in the Tlapana Formation, made up of carbonaceous mudstone, coal and sandstone.
|
|
Geology
|
The target coal seam on Foley is referred to as the Sese Main Seam and is made up of three separate coal plies that form an approximate 20m thick package named from the bottom up as the SS, SST and SSU Seams.
|
|
Geology
|
The SS Seam is on average 6.83m thick and is the best quality of the three plies.
|
|
Geology
|
The SST Seam is on average 7.95m thick and the SSU Seam is on average 3.50m thick.
|
|
Geology
|
The seams are almost horizontal with a gentle dip (

‐ mismatch between the lithological and sampling logs
|
|
‐ duplicate records
|
|
‐ anomalous analytical data
|
|
Minor errors were found and corrected.
|
|
No boreholes were excluded from the modelling database.
|
|
Site visits
|
The Competent Person was involved with the design of the drilling programme and the logging and sampling procedures.
|
|
Site visits
|
Several site visits were conducted throughout the project.
|
|
Geological interpretation
|
Initial seam correlation was carried out by the Project geologist based on their experience.
|
|
Geological interpretation
|
The CP conducted detailed seam correlation as part of the modelling process using the downhole wireline logs, seam qualities and cross‐sections drawn across the project area.
|
|
Geological interpretation
|
An interpreted surface for the level of weathering was created.
|
|
Geological interpretation
|
The resources were cut towards the north of the project due to level of weathering. It was assumed the seams were weathered in this direction based on drillhole information, however there might be upside potential for unweathered coal in this area as the surface topography changes.
|
|
Geological interpretation
|
The extension of seams beyond drillhole intersections is based on information from neighbouring properties.
|
|
Geological interpretation
|
Basic statistics were used to check the seam correlations, including histograms and scatterplots.
|
|
Dimensions
|
The coal seams extend across the entire project area with the exception of erosion from weathering.
|
|
Dimensions
|
The extents of the seams in the project area are 6.3km strike by 1.1km.
|
|
Estimation and modelling techniques
|
Micromine modelling software was used to create the geological model and resource estimation
|
|
Estimation and modelling techniques
|
Seam roof and floor surfaces were gridded using inverse distance squared algorithm and a search radius of 2000m.
|
|
Estimation and modelling techniques
|
A grid cell size of 50 x 50 was applied and the minimum and maximum extents are as follows:
|
|
Estimation and modelling techniques
|
‐ min = X 500849.24/ Y 7618791.47
|
|
Estimation and modelling techniques
|
‐ max = X 507849.24/ Y 7624091.47
|
|
Estimation and modelling techniques
|
The roof and floor surfaces were viewed in comparison with the drillhole intersections to ensure correct correlation.
|
|
Estimation and modelling techniques
|
The roof and floor surfaces were used to create solid wireframes which were then cut according to the seam extents.
|
|
Estimation and modelling techniques
|
Volumes for the solid wireframes for each seam were used together with the average modelled RD per seam to create a tonnage for each seam.
|
|
Estimation and modelling techniques
|
No previous resource estimations have been carried out for this specific portion of the project in isolation.
|
|
Estimation and modelling techniques
|
The waste parting between the SSU and SST seams has not been modelled.

Mining factors or assumptions
|
Throughout modelling the possible mining method was considered.
|
|
Mining factors or assumptions
|
The deposit is shallow and opencast extraction was deemed appropriate.
|
|
Mining factors or assumptions
|
Due to the thickness of the seams and the waste parting, selective mining of each ply was believed to be appropriate and as such each seam is reported separately.
|
|
Mining factors or assumptions
|
A competent mining engineer converted TTIS to MTIS applying appropriate assumptions.
|
|
Mining factors or assumptions
|
As part of this process a preliminary review of the stripping ratios was also conducted. The average stripping ratio is estimated at 1:3
|
|
Metallurgical factors or assumptions
|
Based on knowledge of the neighbouring properties coal deposits (as reported in the public domain), the coal at Foley was considered for beneficiation.
|
|
Metallurgical factors or assumptions
|
Resources have been reported for both raw and washed coal
|
|
Metallurgical factors or assumptions
|
A washed coal product of >20MJ/Kg CV was targeted.
|
|
Metallurgical factors or assumptions
|
Additional work on the metallurgical factors is being conducted by Sedgman.
|
|
Environmental factors or assumptions
|
No environmental work has been carried out as part of this project.
|
|
Environmental factors or assumptions
|
The surface at Foley is dominated by stunted Mopane woodland and no major environmental issues have been noted.
|
|
Environmental factors or assumptions
|
Additional environmental work is required.
|
|
Bulk Density
|
There is no bulk density data for the Foley Project.
|
|
Bulk Density
|
The Relative Density values used for tonnage estimation were those reported by the laboratory, which were then modelled in Micromine.
|
|
Classification
|
Boreholes with quality data only have been used as Points of Observation for
Resource Classification.
|
|
Classification
|
Due to the continuous nature of the coal seams and low variability in seam quality, the use of 1000m spacing is deemed an appropriate guideline for Indicated Resources and 4000m for Inferred Resources.
|
|
Classification
|
All of the data used for the resource estimation has been drilled by A‐Cap and validated by the CP and is considered reliable.
|
|
Classification
|
The results appropriately reflect the view of the CP.
|
|
Audits or reviews
|
No independent reviews or audits have been completed on the Coal Resource estimated.
|
|
Discussion of relative accuracy/confidence
|
The estimation is a local estimation suitable for use in conversion to Coal
Reserves.
