3.3Exploration

3.3.1Introduction

The Tinga Prospecting License was acquired from Semafo due to the existing Far East resource (not NI 43-101 compliant), and forms a strategic part of the neighbouring Kuri Prospecting License and Kalebu Reconnaissance Licence. It is felt that there is considerable upside potential to the licence.
Initially Birim undertook a remote sensing desktop study of the available datasets and produced a first pass regional scale geological map. This enabled the location of the Tinga gold mineralisation to be examined in context of the regional structure.
Outcrop is scarce in the project area, but some geological observations were taken in and around the galamsey areas.
Birim undertook a 63 hole drilling programme (7942.16m of RC and diamond), the aim of the drill programme was to verify selected Semafo intersections and to expand the existing resource base with the aim of bringing the deposit inline with NI43-101 requirements. Also to develop a geological understanding of the dynamics which generated the Tinga deposit and a robust exploration model for the Tinga style deposit, and most importantly to further extend the resource along strike and down-dip. The mineralized shear system remains open to the north. Both the Tinga and adjacent Kuri targets constitute a new node of mineralization, which Birim hopes will attain critical mass and warrant development work.
This programme was successful and extended the mineralisation both to depth and along strike. Lithological, structural and mineral alteration information was recorded from the drill programme. After successful completion of the 63 hole Phase One drill program and based on analysis of all assay results received, it is the Company's intention to undertake a second phase of drilling on the mineralised shear system which remains open to the north.
Due to the success of the drill programme and in conjunction with the regional interpretations Birim then undertook an extensive gradient array induced polarisation (IP) survey. This survey was planned to identify the IP signature of the Far East mineralisation, with the aim of identifying similar IP signatures in proximal prospects (defined by galamsey and soil geochemistry) and in ‘unexplored’ ground to the east of the Far East mineralisation.
IP targets and interpreted upside potential from previous Semafo exploration work were drill tested by means of a regional reverse circulation scout drilling programme. This programme consisted of drilling 33 holes for a total of 2,283m. The programme tested 17 individual targets.

3.3.2Work Completed

3.3.2.1Remote Sensing Interpretation

A number of regional datasets were examined; these included airborne magnetic and radiometric data, and landsat imagery. Relevant features from each dataset were digitised and incorporated into the companies GIS database.
The ternary map shows the presence of the central Tinga intrusive plug. While north-south trending dykes are evident on the aeromagnetics. A weak magnetic rim and coincident potassium anomaly defines the rim of the Tinga intrusive.
The landsat indicates a NE trending lineament that is located proximal to the Far East mineralisation.

On the EM5 image, a number of structural lineaments can be identified these include predominantly NE striking lineations, with subsidiary ENE and N-S striking lineaments.

The age relationships of these structures could not be determined.

3.3.2.2Drilling

3.3.2.2.1Introduction

Two phases of drilling have been undertaken on the prospect. The aim of the first programme was to verify selected Semafo intersections and to expand the existing resource base with the aim of bringing the deposit inline with NI43-101 requirements. Also to develop a geological understanding of the dynamics which generated the Tinga deposit and a robust exploration model for the Tinga style deposit, and most importantly to further extend the resource along strike and down-dip.
The first programme consisted of 63 Reverse Circulation (RC) drill holes (totalling 6,425.85 meters) with some Diamond tails on the deeper holes or in the vicinity of the expected mineralized zone and one (1) Diamond drill hole at a drill depth of 1,516.31 meters were completed. Total number of 7,975 drill samples was realized from the drill program. Quality assurance and quality control samples realised an additional 1,026 samples for a total of 9,001 samples.
The second drill programme was aimed at testing 17 geophysical targets and upside potential from the Semafo exploration programme. To this end 33 reverse circulation holes were drilled for a total of 2,283m. This programme resulted in a total of 2,475 samples being submitted, of these 2,283 were original drill samples and 192 were QC /QA samples.

3.3.2.2.2Methodology

Reverse circulation and diamond drilling was undertaken utilising Geodrill subcontractors which assigned a dual purpose UDR650 drill rig to the concession for the duration of the drill programmes. A 5 ¾ inch hammer was used for RC drilling while the HQ core was drilled. HQ3 was used to improve core recoveries through the overburden and saprolite horizons. A down hole survey log indicating magnetic azimuth and dip was recorded. Alloy rods were utilised in order to eliminate the effect of magnetism on the magnetic readings produced during the survey.
The core was orientated using the Ezymark system. The RC drilling produced lithological, alteration, assay and mineralisation logs. Diamond drilling produced lithological, structural, alteration, mineralisation and various geotechnical logs.
A basic structural analysis, including stereographic plots of poles to lithological contacts, dykes, fault planes, intersection planes, fracture planes, veins and joints was undertaken and plotted.
RC drill samples were collected at the cyclone at 1m intervals, these samples were split using a Jones Riffler, which produced a 12% sample split. This sample was marked and bagged for assay. The duplicate sample was transported to Nsawkaw base camp for storage, while the rejects were stored on a sample farm at the company’s field camp on the Kuri concession.
Diamond core was geologically logged and marked for sampling based on mineralisation and alteration boundaries; care was taken to include the contacts in the sample. In the hanging wall and footwall 1m samples were taken. Diamond core was cut onsite at Birim Goldfields’ Kuri regional camp.

3.3.2.2.3Quality Control / Quality Assurance

The drill-hole samples were submitted to SGS Laboratories (Tarkwa). The samples were analyzed by fire assay using a standard 50g charge with an AAS finish, a gravimetric finish was requested for any fire assay results which reported above 5 g/t gold. Birim and SGS have routinely inserted quality control samples into all sequences of submitted samples to ensure full compliance with NI 43-101 securities regulations.

3.3.2.2.4Results And Conclusions- Drill Programme One

Two noteworthy drill intersections were achieved in the latest round of results. Drill BFE021 cut 7.1 meters of 3.06 g/t gold at a vertical depth of 87 meters, and 125 meters laterally from this result BFE023 defined 7.8 meters at 4.89 g/t gold at a vertical depth of 91 meters. These two intercepts appear to define a high-grade, shallowly plunging (20 degrees) thickening within the deposit that can be traced northeastwards for a current minimum strike of 170 meters from Semafo's unpublished drill hole intercept in RTC030 (14m@ 7.24 g/t Au at 53m vertical depth).

A summary of the significant intersections (>5 gram meters) is presented in the table below.

Table 2: Significant drill intersections from Drill Programme One

* Drill intersections have not been corrected for width.

The drilling provided a relatively clear view on the mineralisation and alteration styles present at Tinga. The drill holes consisted mainly of hornblende gneiss’s and quartz-feldspar porphyries. There is a ferruginised (haematite?) envelope proximal to the Far East mineralisation. The mineralisation is represented by totally to partially replaced hornblende gneiss/QFP which has been silicified and sulphidised. The gold is associated with the silica-euhedral pyrite assemblage. The edges of the mineralised zone are normally chloritised possibly representing an altered mafic(?) lithology. The hornblende gneiss’s and QFP lithologies have been intruded by gabbroic dykes and sills; there is also a late brittle stage of faulting present. It seems like the mineralisation was quite late in the tectonic history as the euhedral pyrites are undeformed. There is an earlier pyrite event, which has been isoclinally folded within graphitic schists on the edges of shear zones. This phase of pyrite does not have gold mineralisation associated with it. Hydraulic breccias were noted in some of the core in the southern part of the deposit.

3.3.2.2.5Results And Conclusions- Drill Programme Two

This programme was successful in highlighting areas for follow up and eliminating barren areas. It should be noted that with the Tinga Far East type mineralisation, assays in the vicinity of 0.15 – 0.2 g/t Au can be proximal to a 7m intersection running at a few grams per tonne.
The holes intersected similar alteration styles to that surrounding the Tinga Far East deposit i.e. silicified/ferruginised deep iron red alteration of the hornblende gneiss and quartz-feldspar-porphyry units. Where this is coupled with a lift in the background of geochemical values it is recommended that detailed mapping, trenching and hopefully drilling be undertaken as follow up stages.
A summary of the significant intersections is presented in the table below:

Drill Hole	From (m)	To (m)	Width (m)	Grade (g/t Au)	Type

Table 3: Significant drill intersections from Drill Programme Two.
A brief review of the holes is documented below:

Far East Drill Prospect

BFE077 and BFE078 Drill Fence Target: The Far East mineralization is proximal to a NE trending chargeable IP axis, as one moves SW along this axis the Semafo trenches and boreholes diverge away from this axis.  The aim of the fence was to test the SW extension of the axis.  The holes were planned to intersect the strongest signature of the chargeability high.  BFE077 is only located 13m away from RTC003. BFE078 and BFE077 were drilled purely to get lateral coverage. BFE077:  this hole had 2 intersections:  5m to 11m = 6m @ 2.15g/t Au. The first meter of this is at the base of the ferricrete/laterite unit and is quartz rich.  The remainder of the intersection occurs in a silicified/ferruginised hornblende gneiss reminiscent of the Far East-style of mineralization (without visible pyrite).  This appears to be an extension of the Far East alteration zone. 32m to 34m = 2m @ 21.23g/t Au.  This seems to be a subvertical silicified ferruginised hornblende gneiss, the ferruginisation is pervasive for a few meters either side of the mineralization. BFE078: the chargeability axis is coincident with a quartz-feldspar-porphyry (QFP) unit in the hole. This QFP unit is bounded by quartz veins.  The only grade in the hole was in the first meter which is comprised of lateritic material. Interpretation: There is a possibility of a mineralized east-west subsidiary which intersects trenches TFE7440, TFE7420 and possibly RTC036, this would also intersect BFE077 intersection 1 area.  It seems like the chargeability axis is related to a quartz-feldspar porphyry unit (the reason that this is chargeable is unknown at this stage).  It is suggested that a drill fence is planned further to the SW at the confluence of the chargeability axis and the resistivity axis.  There is generally a lift in grade in close proximity to the resistivity axis, and it is possible that as these axes anastomose the widths (and grade?) could increase.  The chargeability is directly related to magnetite content i.e. towards the residual chargeable high the magnetite content increases.  The mineralisation occurs within a low chargeable zone, but on a resistive high.

BFE072 Target: Convergence of 2 resistivity axes and a chargeability axis, and the proximity of a soil gold anomaly. BFE072: no intersection achieved.  The chargeability axis appears to be related to a QFP unit.

BFE069–BFE070–BFE071 Drill Fence Target: Anastomosing chargeable/resistive axes and a fault, all in close proximity to a soil gold anomaly. BFE069: this hole was planned to intersect a chargeability axis, the hole intersected a QFP unit directly beneath the trace of the chargeable axis.  This zone was silicified and partially ferruginised BFE070: this hole intersected a resistive axis which was represented in the drill chips by a silicified zone. BFE071: the interpreted IP fault, is represented by a zone of silicification and QFP. Interpretation: No further follow up recommended – there was no hint of mineralization in this drill fence.  The soil gold anomaly is still unexplained.

BFE073-BFE074-BFE075-BFE076 Drill Fence Target: A chargeable axis flanked by parallel resistive axes, and coincident with a soil gold “outlier” anomaly, located to the SE of the Far East zone. Interpretation: The bulk of this drill fence is comprised of QFP which seems to replace the hornblende gneiss (along structures – shears?). Hole BFE074 and BFE075 are drilled within a chargeable high and are ferruginised. This ferruginised zone seems to be flanked by silicification and in the extreme east (BFE073) there is some carbonate alteration present at the top of the hole.  BFE076 has a 2m intersection, this is located at the contact of a QFP unit and the host hornblende gneiss.  There is a resistive axis present to the east of the intersection and there is a slight possibility that the mineralization may be dipping NW, should the resistive axis be a mineralized structure and is the surface trace.    In BFE075, the chargeable axis is once again coincident (if vertical) with a QFP unit at the centre of the structure.

Regional Targets on Tinga Concession (not on Far East Drill Prospect)

BTI001 and BTI002 Drill Fence Target: Soil gold anomaly and IP chargeability high. Interpretation: BTI001 intersected some sulphides towards the base of the hole. This indicated that he chargeability axis has a moderate to steep SE dip.  No significant grade was intersected in these holes (highest was 0.02ppm) and no further follow up is recommended on this IP axis.

BFE064 and BFE068 Drill Fence Target: Two (2) pole–dipole anomalies with proximal soil anomaly.  This target represented a strong, well-rooted geophysical anomaly to the geophysicists (SAGAX). Interpretation: From E (BFE064) to NW there is a lithological change from biotite gneiss to hornblende gneiss. This occurs close to a geophysically-interpreted lithological change.  The apparent dip on the contact is 36 deg towards 132 true (this may be indicative of a thrust), there are two zones of pyrite mineralisation in the biotitic hanging wall these occur at 7m and 26m above the lithological contact but there is no associated gold mineralization.  The increased level of sulphide (pyrite) does seem to explain the pole–dipole anomalies.  The entire drill fence is silicified.  BFE067 and BFE068 have some minor gold association with a thin pyrite band (BFE068 = 0.19ppm and BFE067 = 0.4ppm), the apparent dip on this mineralized unit is 23 deg towards 134 true (almost mimicking the thrusted(? ) contact between the biotitic and hornblende rich granitoids).  BFE066, BFE067 and BFE068 all have varying amounts of pyrite mineralization in them, this explains the pole–dipole anomalies in this area.  Where the geophtsicists interpreted a fault (intersected in BFE067), the gold increases (0.4ppm) and there is an increase of chloritisation.  This provides confidence in the geophysical interpretation.  It is recommended that the mineralized zone is projected to surface and trenched, it is recommended that the soils to the northwest of the borehole mineralisation are re-sampled in order to check for any parallel shallowly dipping mineralized thrusts. From the borehole chips and the IP contact resistivity map it can be interpreted that there are varying amounts of residual lateritic material present, this could have masked the soil response of any surface expression of mineralisation in this area.

BTI005 and BTI006 Drill Fence Target: Intersection of a chargeability axis and a resistivity axis, associated with the core of a soil gold anomaly. Interpretation: Both holes intersected mineralization, although BTI006 was the better of the two holes.    BTI005 has 2 narrow intersections: 2m @ 2.48g/t Au this is associated with a QFP unit which has haematite alteration.  1m @ 0.42g/t Au, occurs below a narrow quartz vein within a QFP unit and also is associated with hematisation.  BTI006 has 2 intersections although these average out at 20m @ 0.54g/t Au and the entire intersection has pyrite developed (the core of this anomaly is 5m @ 1.32 g/t Au, which occurs adjacent to a quartz vein.  The 20m zone has pyrite association, this is flanked by chlorite, which in turn is flanked by haematisation. Almost the entire hole is drilled through QFP, with narrow hornblende gneiss units.  The mineralization cannot be correlated between the holes as the mineralization assemblage is completely different, and it is therefore interpreted that the mineralisation is dipping sub-vertically, this is supported by the chargeable signature, i.e. shadow zone / contours even on both sides of the axis.  It is recommended that a detailed 15m spaced soil grid is completed over this target, this should provide some clarification as to which axis (chargeable or resistive) is mineralized and whether it is just the intersection point which is mineralised.  It is also recommended that the intersection point of a resistive and chargeable axis located to the northwest is drill tested.

BTI007 (PROSPECT ‘B’) Target: This hole was originally planned to test Semafo trench TME 7360, which had an intersection of 13.5m @ 0.48g/t Au.  It was mistakenly moved to the NW of trench TME 7410, and was drilled to the NW.  The hole did not intersect mineralization. Interpretation: Trench TME 7360 therefore still needs to be drill tested.  There is no geophysical (IP) support here.

BTI003 and BTI004 Drill Fence (PROSPECT ‘B’) Target: This drill fence was targeted at a pole-dipole anomaly which was coincident with the intersection point of 2 interpreted faults (gradient array; E-W trending and NE trending) and an interpreted lithological boundary (gradient array; NE trending).  These features are located within an area of anomalous soil mineralisation. Interpretation: No obvious lithological contact was noted in the geology logs, however the holes consist of a complicated alternating sequence of hornblende gneiss and QFP, possibly indicative of a structurally complex area.  In BTI004 there is an increase in sulphide (pyrite) towards the core of the structure. Another hole needs to be drilled to the NW.  BTI003 intersected 1m @ 2.16g/t Au and this was associated with QFP.  BTI004 intersected a 2m zone of low grade mineralization (0.21ppm and 0.35ppm) this is in close proximity to a QFP unit, the apparent dip can be measured as 23 deg towards 137 true, which is very similar to the thrusted contact and mineralisation found in the BFE064-BFE068 drill fence.  The alteration logging how that BTI003 and BTI004 show pervasive haematisation of the lithologies.  It is recommended that a further hole in the fence be drilled toe-heel from BTI004 to the north-west.

BTI008 and BTI009 Drill Fence Target: This drill fence targeted a pole-dipole anomaly and associated chargeability axis. Interpretation: The chargeability axis is associated with a QFP unit in BTI009.  There is some minor sulphide in BTI008 which may be responsible for the pole-dipole anomaly.  The holes consist of an alternating sequence of hornblende gneiss and QFP units. The hornblende gneiss is generally silicified while silicification in the QFP was not recorded.  BTI008: there are 3 narrow zones of elevated background values within this hole.  Two are located within the hornblende gneiss and the third is a possible shear and is associated with a chloritised unit and has some carbonate alteration associated with it (the values for the third zone are: 0.21ppm and 0.17ppm).  BTI009 has 4 zones of elevated background associated with a: quartz vein (2m containing 0.15ppm and 0.17ppm). hornblende gneiss unit (3m wide containing 0.22ppm, 0.06ppm and 0.16ppm). QFP unit (1m @ 0.62g/t Au). hornblende gneiss unit (1m @ 0.26g/t Au).  Although these levels of values can be significant in the Tinga Far East-style of mineralization, we do not feel that there is enough complexity in the holes or the IP to warrant further follow up work.

BTI012 Target: ENE trending lithological boundary and fault, which intersects a NE trending chargeability axis, and a pole–dipole anomaly. Interpretation: The top 13m of the hole has an elevated background with values reaching 0.20ppm (anomalous in this area).  The main chargeability axis is associated with a QFP unit, silicification and pyrite.  There is also some pyrite lower in the hole, this pyrite occurrence is associated with: silicified hornblende gneiss, and the contacts of a quartz vein – there are no elevated gold values in the lower portion of the hole.  It is recommended that a hole be drilled in a fence to the SE of BTI012, this is justified by the presence of 13m of anomalous background in BTI012.

BTI013 Target: Peridotite/amphibolite unit and a zone of artisanal workings in soil close to a dyke/granite contact containing visible gold. Interpretation: This hole did not test the target, only 2 narrow intersections of peridotite material were intersected (13-15m, 25-26m).  It is probable that the surface expression is a sill type feature and that the hole only tested narrow feeders to the sill.  This will be followed up at a later stage.

BTI014 Target: Moderate strength pole-dipole anomaly, chargeability axis. Interpretation: The chargeability axis appears to be subvertical; this observation is based on the expression of the chargeability shadow.  The chargeability axis is related to a QFP unit in the hole, the base of which has a lift in the gold background to 0.50ppm Au over 1m.  The hornblende gneiss is silicified and there are two occurrences of pyrite towards the base of the hole which could explain the pole-dipole anomaly.  There is a slight lift in the background values (from 0.01ppm to 0.03ppm) in the vicinity of the pyrite mineralization.  It is not recommended that any further follow up work be done on this target.

BTI015 Target: Intersection of chargeability and resistivity axes. The resistivity axis, has a value of 28g/t Au associated with it along strike to the NE. Interpretation: If the resistivity and chargeability axes are vertical then they are related to biotite gneiss in the hole.  The upper 25m of the hole is interesting with fluctuating gold backgrounds (up to 0.16ppm Au).  The upper portion of the hole consists of peridotite, QFP, hornblende gneiss, and has chlorite alteration, silicification and some pyrite developed.  There is also some carbonate alteration associated with the contacts of one of the silicified zones.  It is recommended that either a second hole located to the SE of BTI015 is drilled, or preferably that a detailed limited soil grid is planned around the hole, to test for anomalous gold mineralization and to test the intersection point of the chargeable, resistive axes with the interpreted trace of a fault.

BTI016 (PROSPECT ‘C’) Target: To test trench intersections in TMW7200 and TMW7220 Interpretation: The hole returned an intersection of 8m @ 2.29g/t Au, with a high of 2m @ 8.82g/t Au.  Trench TMW7220 returned a zone of 8.5m @ 0.64 g/t Au.  The apparent dip between the trench mineralised zone and that of the borehole is 31 deg towards 137 degrees true.  Trench 7200 (14m SW of the drill hole) returned an intersection of 2m @ 5.29g/t Au and a second zone of 1m @ 1.62g/t Au.  A hole was collared to the W of the 2m zone and was drilled to the NW and intersected 2m @ 17.8g/t Au which indicates that either the 1.62ppm trench intersection increases in grade substantially to depth and is SE-dipping or that the 2m trench intersection is dipping to the NW.  In all there is conflicting information in the area and it is recommended that detailed mapping and possibly some extra trenching is undertaken in order to elucidate the structure of the area before any further drilling is undertaken.  It is however a high priority area given the high grades.

BTI017 and BTI018 (PROSPECT ‘C’) Target: These holes were targeted at a pole-dipole anomaly and intersecting a NE chargeable axis and a north-south trending resistive axis.  Interpretation:  From the drill section it can be seen that there is a bit of noise in the upper portion of the holes, and that there is relatively flat lying magnetite alteration boundary.  The gold values in both holes are either within the magnetite rich alteration zone or proximal to the contact.  The pole–dipole anomaly is explained by the presence of cubic pyrite.  There may be a correlation between pyrite and gold in BTI018.  The magnetization trend has an apparent dip of 5 deg towards 139 true.  Pyrite alteration/mineralization cannot be traced between the two holes.  The chargeability axis is related to a QFP unit with a lift in gold.  The resistive axis is related to a QV with a lift in grade.  The lithological contact (interpreted by SAGAX) is represented in the hole by a pyrite zone, QFP unit and a lift in gold background.

3.3.2.3Gradient Array Induced Polarisation survey

3.3.2.3.1Introduction

SAGAX were contracted in to undertake a gradient array induced polarisation electromagnetic ground survey. A survey grid was planned such that the lines would cut the structures normal to the strike of the structures. The aim of the programme was to identify lithological boundaries, structural controls of the Far East mineralisation and to identify similar geophysical signatures for future exploratory drilling.
Two phases of IP survey were undertaken; the first was located in order to cover known mineralisation at the Far East Prospect and to extend into unexplored areas both north and south of delineated mineralisation (i.e. areas where the gold-in-soil response could have been subdued due to the presence of the clay drape). The second programme was planned to infill between the original four km² and thus provide total coverage of the Far East mineralised zone. This second programme was also extended to cover the remaining soil geochemical target i.e. Prospects ‘B’, ‘C’, ‘D’ and ‘E’, for a total of 11km² of gradient array IP and 2.59km of pole-dipole.
These prospects have had varying degrees of trenching and drilling on them, undertaken by Semafo. No coherent mineralised zone was defined, and it was hoped that the gradient array IP would provide a geophysical signature that would be traceable along strike.

3.3.2.3.2Methodology

The grid and station points were planned in ARCVIEW and the points were laid out by means of handheld GPS. Birim Goldfields employees surveyed and cut the survey grid. This was then re-surveyed using a differential gps to fix the actual measured ip points. This data was then sent to SAGAX for inclusion in the post processing. Data from two pole-dipole lines were collected.

3.3.2.3.3Results and Conclusions

IP imagery was produced for Total Conductivity, Total Chargeability, Residual Chargeability and Total, Contact Resistivity and Residual Resistivity.
Interpretation of these IP datasets confirmed the concentric nature of the pluton. With resistive axes curving as they progress along strike. A number of resistive (silicified) axes are present some of these coincide with chargeable axes. This programme has identified a number of prospective exploration targets which coincide with soil geochemical highs.
The QFP units seem to be associated with chargeable axes and the reason for this is not yet understood. There is some magnetite and pyrite in the system which accounts for most of the pole-dipole and some of the gradient array chargeability anomalies. Resistive axes are normally related to both discreet quartz veining and zones of intense silicification.
