QUARTERLY REPORT
For the period ended 31 December 2013
Mining
A total of 2,879,791bcm of ore and waste was mined during the Quarter, nearly 12% more than in the September 2013 quarter. The ore mined included 5,614t of oxide ore at 0.6g/t gold and 1,365,183t of transitional and primary ore at 1.0g/t gold. The quarter-on-quarter increase in total material movements reflected a 25% increase in waste movements (associated with stripping of the AG Stage 3 pit) combined with a 24% decrease in the quantity of ore mined relative to the prior period.
During the Quarter, the ROM ore stockpiles that include both high and low grade ore (but not mineralised waste) plus crushed ore decreased by 550,744 tonnes to 3,921,802t grading 0.5g/t gold, and containing approximately 68,321oz of gold. The reduction in stockpile reflected the plan to process stockpiled ore to offset reduced ore production while mining focussed on stripping Stage 3 of the AG Pit. These ore stockpiles were made up of approximately 42% oxide ore and 58% transitional/primary ore. Approximately 5% of the stockpiled ore is classified as medium/high grade, containing greater than 0.6g/t gold, while 95% of the ore is classified as low grade containing 0.4 to 0.6g/t gold.
Processing
Gold production of 48,360oz during the Quarter was 6% above September 2013 quarter production, notwithstanding the fact that the head grade of ore treated (1.00g/t gold) was approximately 5% lower than in the September 2013 quarter (1.05g/t) .The reduction in head grade was in line with expectations and was a reflection of the strategy of processing a blend of ore drawn from stockpiles and the existing open pits in FY2014.
The effect on production of the decreased head grade was offset by an improvement in the gold recovery rate (84.4% compared to 83.4%) and improvements in the availability and usage of the process plant, including the primary crusher, oxide circuit and SAG mill. These parameters are summarised below.

All-In Site Costs
Total all-in site cash costs (including production, royalties, investment in pre-stripping and inventory, development and sustaining capital) for the Quarter were US$1,228/oz which was 8.5% lower than in the September 2013 quarter. This improvement in costs was the result of an 11% decrease in unit mining costs and a 7% decrease in unit processing costs.
In terms of all-in site cost for the December Half Year, the improvement in unit costs achieved during the Quarter was insufficient to offset the impact of higher than expected costs in the September 2013 Quarter and as a consequence, for the December Half Year, the total all-in site cash costs (including production, royalties, development and sustaining capital) were US$1,283/oz, slightly above the upper end of the cost guidance range for the Half Year of US$1,050 to 1,250/oz.
Details of site operating costs for the financial year to date are as follows:

*Note: Investment or (reduction) as the case may be.
Of the US$85/oz spent on sustaining capital during the Quarter, approximately 50% related to payments associated with community relations activities including crop compensation committed in prior periods for areas that will be affected by mining of the eastern pits and purchase of land for relocation housing. The remaining 50% related to an assortment of expenditure relating to plant upgrades, security and site upgrade projects. This allocation of sustaining capital was very similar to that in the prior quarter.
EGM Production and Cost Guidance

Project Development
Sissingué Gold Project – Côte d’Ivoire
Perseus has deferred commencement of development of Sissingué pending a reassessment of the mine plan in the light of lower gold prices and clarification of a number of issues, including:
-
Finalisation of the new mining code in Côte d’Ivoire;
-
The granting of a request to extend the date for first production specified in the Sissingué Exploitation Permit beyond August 2014;
-
Exploration of nearby exploration licence areas such as Mahalé with the view to delineating new gold deposits that could be processed at the proposed Sissingué gold facility;
-
Complete a review of the capital and operating cost estimates for Sissingué applying current cost and revenue expectations to revise mine planning scenarios.
Exploration
Ghana
During the Quarter, minimal amounts were spent by Perseus on exploration activities in Ghana at the EGM and on adjoining licence areas.
Exploration activities were limited to geological mapping and prospecting plus data interpretation for planning of future Resource / Reserve drilling programs at the EGM. No drilling occurred during the Quarter.

QUARTERLY REPORT For the period ended 31 December 2013
Côte d’Ivoire
During the Quarter, a total of US$1.5M was spent by Perseus on exploration activities in Côte d’Ivoire as follows:
Mahalé Licence
A total of 28,568m (16,435m September 2013 Quarter) was drilled at the Bélé anomaly on the Mahalé licence during the Quarter consisting of 12,871m (132 holes) of reverse circulation (“RC”) drilling, 11,875m (441 holes) of scout Air Core (“AC”) drilling plus 3,872m of shallow rotary air blast (“RAB”) drilling to nest for near-surface geochemical anomalies, representing 670 sample points. The Mahalé Project is located 30-40km west-southwest of the Sissingué Gold Project as shown below.
Perseus’s RAB rig was utilized to drill auger-style vertical holes into saprolite to 5.5m depths on average, on a nominal grid spacing of 100m X 100m across the Bélé soil anomaly to identify targets for follow-up drilling with AC and RC drills. Fences of wide-spaced AC drill holes were drilled in select areas of the Bélé prospect as a first pass drill test of gold in soil and/or auger anomalism (Figure 1).
Page | 14
QUARTERLY REPORT
For the period ended 31 December 2013
First pass RC drilling was conducted to test AC drilling and auger anomalism at depth at the Bélé East, West and Central prospects. Although essentially an exploratory RC drilling campaign, RC drill hole spacing was fairly tight locally, down to 40m X 40m spacing, in order to better understand the nature, geometries and continuity to the mineralisation. A number of significant RC drill intercepts were returned from the Bélé East, West, and Central prospects, which is encouraging and suggests that a fairly extensive mineralising system is present at Bélé along the margins of a granitic intrusive that is estimated to be 3 kilometers in width, east-to-west, and at least 2 kilometers in a north-south direction. A number of significant RC intercepts are open-ended to depth and to varying degrees along strike. However, further drilling will be required in order to delineate a potentially economically viable resource, if one is present (Refer to Figure 1).
Further work at Bélé will commence in early 2014 with a program of ground geophysics, gradient IP and magnetics, before commencing further drilling. Given that the gold anomalism appears to be associated with the presence of pyrite, IP chargeability should be an effective tool to search for the extensions of gold mineralized zones and possibly locate additional targets for drill testing. Most of the area shown in Figure 1 will be targeted for ground geophysics.
Significant RC and AC drill intercepts returned during the Quarter are listed in Table 1 of Attachment 1, with the highlights as below. As of December 31, 2013 assays were still pending for 43 RC, 82 AC and 180 auger drill holes.
Significant RC intercepts attained at Bélé included:

Mbengué and Napié Licenses
There were no exploration activities on the Mbengué and Napié Licenses during the Quarter.
Processing, imaging and interpretation products from the airborne magnetics and radiometrics surveys flown over Mbengué and Napié were received late in the Quarter and are under review to prioritise further exploration drilling on both projects.
Tengréla Licences
No exploration work was conducted on the Tengréla South or Sissingué license areas during the Quarter.
Burkina Faso
During the Quarter the Company entered into a farm-in agreement with West African Gold Limited (“WAG”), an Australian unlisted junior explorer, in respect of four exploration permits (Koutakou, Barga, Touya and Tangaye) in the orth of Burkina Faso. Under the terms of the agreement Perseus must spend a minimum of US$250,000 during the first year on exploration. Perseus may earn a 50% interest in the permits by spending US$2M and up to an 80% interest by spending an additional US$2M within 5 years. The map below shows the locations of WAG’s tenements that are covered by the farm-in agreement.

Corporate
Cash, Bullion
Based on the gold price on 31 December 2013 of US$1,201.50/oz and an A$:US$ exchange rate of 0.8874, the total value of cash and bullion on hand at the end of the December 2013 Quarter was $28.2M, approximately $0.9M more than at the end of the September 2013 quarter ($27.3M). In addition to the above, the Group had a further $10.6M of cash on deposit in escrow accounts providing security for various matters including future environmental commitments.
The Group’s available cash balance as at 31 December 2013 was $16.0M (30 September 2013:$23.1M). In addition, 8,984 oz of gold were held either on site, in the process of being refined or in the Company’s metal account on the 31 December 2013, (30 September 2013: 2,922oz). Based on the parameters described above, this bullion was valued at $12.2M at 31 December 2013.
Gold Sales and Price Hedging
Of the 44,617oz of gold sold during the Quarter (September 2013 Quarter: 49,069oz) at a weighted average delivered price of US$1,318/oz, (September 2013: US$1,342/oz) a total of 23,000oz were delivered into forward sales contracts at an average price of US$1,263/oz with the remaining gold sales occurring at prevailing spot prices.
As at 31 December 2013, the Company’s gold price hedging position included 124,000oz of gold deliverable in quarterly instalments up to and including 31 December 2015 at a weighted average price of US$1,463/oz. This includes a total of 70,000oz of gold deliverable in quarterly instalments during the 2015 calendar year at an average price of US$1,600/oz. The Company also held options to sell a further 9,000 oz of gold at a price of US$1,150/oz at any time up to 10 January 2014, and 9,000 oz of gold at a price of US$1,100/oz at any time up to 31 January 2014.
The total hedge position was “in the money” to the extent of US$31.6M as at 31 December 2013 (30 September 2013: US$14.4M). In the March 2014 Quarter, 8,000oz of gold is scheduled to be delivered at an average price of US$1,269/oz under the hedge programme.
VAT Receivable
Having received cash refunds totalling GHC6.2M to date, during the Quarter, the Company sought to negotiate a factoring deal with a number of financial intermediaries in relation to the outstanding GHC93M (US$39.4M) VAT receivable owed to the Company by the Ghanaian Government. These negotiations were unsuccessful in reaching agreement on terms that were acceptable to Perseus. However, as an alternative, the Company mandated a Ghanaian legal firm that specialises in revenue law to intervene directly with the Government on the Company’s behalf.
This intervention by Perseus’s legal team has resulted in:
-
The Ghana Revenue Authority has advised in writing their decision to issue GHC60M of Treasury Credit Notes to cover that part of the obligation that has been formally audited and approved.
-
Discussions with the Government to include a cash component in the final settlement mix have reached an advanced stage.
-
Negotiations are continuing to ensure that through administrative measures available to the Government, the VAT receivable does not increase in future.

For the period ended 31 December 2013
Working Capital Debt Facility
During the Quarter, discussions were conducted with the Company’s bankers on the provision of a US$25M stand by debt facility to be used as required to fund working capital. A term sheet was negotiated and Credit Committee approval for the term sheet was received and preparation of detailed loan documentation was commenced.
On close examination of the detailed terms of the debt facility, the Company formed the view that on balance, while the facility was available, it was preferable to remain unencumbered in an environment of uncertain gold prices, and therefore decided not to proceed with implementation of the debt facility at this time.

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 nodules) may warrant disclosure of detailed information. |
Reverse Circulation (RC) drill holes (MHLC and MHRC holes) were routinely sampled at 1m intervals down the hole. RC samples were collected at the drill rig by riffle splitting drill spoils to collect a nominal 1-2 kg sub sample and composited into 2m samples for assay. Air core (AC) drill holes (MHAC holes) were routinely sampled at 1m intervals down the hole. AC samples were collected at the drill rig by riffle splitting drill spoils to collect a nominal 0.75-1 kg sub sample and composited into 4m samples for assay. Auger-type sampling was conducted with a RAB rig by drilling vertical holes into the saprolite, 5.5m deep on average, with a nominal 100m X 100m grid pattern. Approximately 1.5-2kg samples were obtained from the bottom 1 meter drilled for assay. Routine standard reference material, sample blanks, and sample field duplicates were inserted/collected at every 12th sample in the sample sequence on average in order to gauge and ensure sample representivity and quality of results from the laboratory. All 2m composited RC samples were submitted to Bureau Veritas Cote d’Ivoire for preparation and analysis by 30g Fire Assay. All 4m composited AC samples were submitted to Bureau Veritas Cote d’Ivoire for preparation and analysis by 1 kg BLEG analysis with AAS finish. All 1m samples from the auger-style RAB drilling were were submitted to Bureau Veritas Cote d’Ivoire for preparation and analysis by 1 kg BLEG 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). |
All RC holes were completed by reverse circulation (RC) drilling techniques with a hole diameter of 5.5 inch and a face sampling down hole hammer. All AC holes were completed by air core (AC) drilling techniques with a hole diameter of 5.5 inch using a face sampling tungsten blade AC drill bit. All Auger-style holes were completed by RAB drilling techniques with a hole diameter of 4.5 inch using a face sampling tungsten blade RAB drill bit. |
| 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. |
A qualitative estimate of sample recovery was done for each sample metre collected from the drill rig. Riffle split samples were weighed to ensure consistency of sample size and monitor sample recoveries. Drill sample recovery and quality is considered to be adequate for the drilling technique employed. |

| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| 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. |
All drill samples were geologically logged by Company Geologists. Geological logging recorded rock types, visual estimates of the abundance of quartz veining and sulphides plus the degree of weathering using a standardized logging system. All (100%) of material drilled via RC, AC and RAB drilling methods was logged representing 12,871m of RC, 11,875m of AC and 3,872m of RAB drilling. Small samples of drill material were retained in chip trays for future reference and validation of geological logging and small samples of coarse and sieved fine drill material were affixed to “chip boards” to aid geological logging and for future reference. |
| 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. Whether sample sizes are appropriate to the grain size of the material being sampled. |
All dry samples were riffle split at the drill rig. Wet samples were sampled at the drill rig by spear sampling. The majority of samples (>90%) were obtained dry. If continuously wet drilling was encountered the hole would be stopped. Routine field sample duplicates were taken to evaluate representivity of samples with the results stored in the master drill database for reference. In the case of case of 4m composited samples from AC drilling, initial assay was by the BLEG method. If analytical results returned > 1.0g/t for a 4m composite, individual 1m subsample rejects were resampled and analyzed for Au by fire assay to confirm representivity. At the Bureau Veritas laboratory, samples were weighed, dried and crushed to -2mm in a jaw crusher. A 1.5kg split of the crushed sample was subsequently pulverised in a ring mill to achieve a nominal particle size of 85% passing 75um. Sample sizes and laboratory preparation techniques are considered to be appropriate for this stage of gold exploration. |
| 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
For RC drill samples, analysis for gold was undertaken at Bureau Veritas Cote d’Ivoire lab by 30g Fire Assay with AAS finish to a lower detection limit of 0.01ppm. Fire assay is considered a total assay technique. For AC drill samples, analysis for gold was undertaken at Bureau Veritas Cote d’Ivoire lab by “BLEG” 1 kg bottle roll analysis. The BLEG method is considered to be a partial leach procedure. For Auger-style RAB drill samples, analysis for gold was undertaken at Bureau Veritas Cote d’Ivoire lab by “BLEG” 1 kg bottle roll analysis. The BLEG method is considered to be a partial leach procedure. No geophysical tools or other non-assay instruments were used in the analyses reported. Review of standard reference material, sample blanks and duplicates suggest there are no significant analytical bias or preparation errors in the reported analyses. Internal laboratory QAQC checks are reported by the laboratory and routine review of the laboratory QAQC suggests the laboratory is performing within acceptable limits. |

|---|---|---|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Drill hole data is captured by Company geologists at the drill rig and manually entered into a digital database. The digital data is verified and validated by the Company’s database Manager before loading into a master drill hole database on a regularly backed-up server. Reported drill hole intercepts are compiled by the Company’s Group Exploration Manager. Twin holes were not drilled to verify results as it is considered unnecessary at this early stage of exploration. Should a resource be delineated on the project, future drilling programs would consider twinning some drill holes to check representivity and repeatability. There were no adjustments to assay data. |
| 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. |
Drill hole collars were set out in UTM grid WGS84_Zone29N. Drill hole collars were positioned using hand held GPS, accurate to +/- 2-3m in the horizontal and 3-6m in the vertical direction. Drill holes were not surveyed for down hole deviation in this program of scout exploration as the relatively short RC and AC drill holes were not expected to deviate significantly nor was there an expectation of resource delineation in this program where hole deviation would be of significance. Locational accuracy at collar and down the drill hole is considered appropriate for this early stage of exploration. |
| 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. |
RC holes were nominally drilled on 40m to 160m spaced east-west orientated drill sections with hole spacing on sections at 40m. AC holes were drilled on wide spaced east-west sections spaced 120m to 240m apart with hole spacing on sections dependant on the refusal depth of holes and generally ranging from 10 to 20m. Auger-style RAB holes were drilled on a 100m X 100m staggered grid pattern. The reported drilling has not been used to estimate any mineral resources or reserves. Sample compositing was performed with 2 X 1m samples composited for RC drill holes and 4 X 1m samples composited for AC holes. |
| 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. |
Exploration is at an early stage and the true orientation of mineralisation has not yet been confirmed. |
| Sample security | The measures taken to ensure sample security. | Samples were stored in a fenced compound within the Company’s accommodation camp in Sissingué prior to sample collection and road transport by Bureau Veritas to the laboratory in Abidjan. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
The Company’s sampling techniques employed in Cote d’Ivoire were last reviewed in a site visit to the Sissingué Gold Project by consultants Runge Limited (now RungePincockMinarco Limited) in August of 2010 and deemed to be of industrystandard and satisfactory. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| 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 reported results are from the Bélé Prospect, an area within the Mahalé Exploration Permit (Permis de Recherche) (e which is held 100% by Occidental Gold s.a.r.l., a wholly owned subsidiary of Perseus Mining Limited. The Mahalé Permit is in good standing, valid through to 19 December 2015. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Historical exploration work in the area presently covered by the Mahalé Permit de Researche is unknown. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Mahalé permit covers greenstone (Birimian metavolcanics and metasediments) plus granitic intrusions in an area 15-40km west of the Syama greenstone belt, likely representing a separate greenstone belt. Gold mineralisation observed in the RC holes is spatially related to a granitic intrusion, occurring along its contacts with mafic metavolcanics and within the intrusion. Gold appears to be associated with pyrite concentrations in turn associated with brittle deformation along and within the granite contact. |
| 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 drill hole colla_ro _elevation or RL (Reduced Level – elevation abovesea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho 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. |
Reported results are summarised in Table 1 within the attached announcement. The drill holes reported in this announcement have the following parameters: oOnly drill holes with combined grade X thicknesses of ≥ 10 gram X meters have been reported. oGrid co-ordinates are UTM WGS84_29N oCollar elevation is defined as height above sea level in metres (RL) and has been estimated by hand held GPS. oDip is the inclination of the hole from the horizontal. Azimuth is reported in WGS 84_29N degrees as the direction toward which the hole is drilled. oDown hole length of the hole is the distance from the surface to the end of the hole, as measured along the drill trace oIntersection depth is the distance down the hole as measured along the drill trace. oIntersection width is the down hole distance of an intersection as measured along the drill trace oHole length is the distance from the surface to the end of the hole, as measured along the drill trace. Auger-style vertical RAB drill holes are considered as geochemical point samples, like soil samples, and not as drill holes per se and are therefore not listed in Table 1. All the Auger-style RAB holes drilled are reported in Figure 2 with those holes considered anomalous indicated. Previously reported drilling results have not been repeated in this announcement. |

| 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. |
Drill hole intercepts are reported from 2m metre down hole samples for RC holes and 4m down hole samples for AC holes. A minimum cut-off grade of 0.5 g/t Au is applied to the reported intervals. Maximum internal dilution is 4m within a reported interval. No grade top cut off has been applied. No metal equivalent reporting is used or applied. |
| 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 reported results are from early stage exploration drilling; accordingly the orientation of mineralised structures is currently unknown. Results are reported as down hole length, true width is currently unknown. |
| 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. |
Drill hole plans with significant assay results are shown in Figures 1 and 2. |
| 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. |
All drill holes drilled during the Quarter and previously have been shown in Figures 1 and 2. Only those drill holes drilled during the Quarter which have returned combined assay intercepts exceeding 10 grams X meters, and are thus considered significant results in an early stage exploration program, have been reported in Table 1. |
| 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 exploration data which is considered material to the results reported in this announcement |
| 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. |
Ground geophysics (magnetics and Gradient IP) is proposed as the next phase of exploration, in order to better target follow up drilling. |
