ASX ANNOUNCEMENT 28 April 2014
Details of results from the drilling program are summarised in Table 1 (Appendix A).
Outcomes of Prestwood Drill Program
Prospect is delighted with the results of the drill program at the Prestwood Mine, which have helped validate its development plan to bring the project into production as a high grade gold mine in the near term. The Company now plans to proceed quickly with shaft rehabilitation and then underground drilling.
Significant points of note from the drill program are;
-
The program confirms that the mineralised reef continues below the historic gold workings, and five of six holes drilled intersected intact Main Reef down dip of the existing workings, to 195 metres below surface.
-
The Main Reef extends down dip to at least 6 Level (195m vertically), but is seemingly open ended. The Bucks Mine situated some 600m to the west is known to have been worked to at least 9 Level (300m).
-
The Main Reef extends NE of the known workings, with a total strike length of > 75m, open ended to the NE.
-
The Main Reef is highly variable in nature, being largely a shear zone of quartz veinlets and varying amounts of pyrite, arsenopyrite, pyrrhotite, galena and magnetite.
-
The evidence of parallel mineralised zones, particularly the very subtle sheared monzonite contact is very encouraging. This is the same setting as the mineralisation at the producing Farvic Mine 4km to east.
-
The presence of high grade intercepts (12.3g/t over 1m) within the shallower shear zone (that also hosts the Prestwood A mine) is also considered highly significant. They present an ideal target for potential larger disseminated deposits, amenable to open-cast extraction.
Schematic images of cross section of all drill holes are appended to this announcement (Appendix B).
About the Prestwood Gold Mine
The historic Prestwood Gold Mine is located approximately 112km south east of Bulawayo in Zimbabwe, and historically produced approximately 499kg of gold (approx. 16,000oz) at 33.1g/t. It is situated within an almost contiguous block of claims covering approximately 25km[2] of the gold bearing Gwanda Greenstone Belt. These claims cover more than nine historic gold mines.
The mine consists of multiple veins in greenstones at or close to the monzonite contact. The Company is of the view that it is particularly prospective as it lies in the same geological setting as the nearby Farvic Gold Mine, located 4km to the east. The significance of minerlisation being intersected at the contact of the greenstones and monzonites cannot be overstated. This minerlisation style is very subtle, supported by the fact there is no surface expression at all at the Farvic Mine. The known monzonite extends for over 5km of strike, within ground held by Prospect.

Figure 1: Prestwood Grid Plan projected over Quick Bird Satellite .
Boreholes BPC001 proved the continuity of the reef, beyond the existing 4 Level workings to the northeast, and BPC003 to BPC006 inclusive demonstrated the down dip continuity of the reef to at least 6 Level (195m vertical depth). BPC002 intersected shear hosted mineralisation, which is likely to have been affected by the geophysically interpreted SE-NW trending shears zone. The monzonite sub-outcrop is shown in blue crosses in Figure 1.

Figure 2: Geological Interpretation Projected over Magnetic Image (Analytical Signal).
The magnetic high areas represent monzonite at, or just under the surface (dark red /purple in Figure 2). The northern third of the area is also thought to be underlain by monzonite, covered with thicker residual soils. The SW-NE shearing which hosts the Bucks, Prestwood and Prestwood B deposits is readily apparent. The more subtle SE-NW direction is also thought to have significance for deposit location.
Prestwood Gold Mine Update
-
Exploration head gear has been erected at the Prestwood shaft and dewatering has been completed to 2 Level.
-
A recently completed ground magnetic survey has identified multiple parallel structures adjacent to the Prestwood Mine. A number of these are being mined artisanally.
-
Shaft rehabilitation is underway and once complete, underground drilling for parallel reefs is planned. Evidence of parallel reefs is supported by the ground magnetic survey completed in January and the existing artisanal surface mining.
Future Plans
The results of the maiden drilling programme have provided Prospect confidence to proceed quickly with shaft rehabilitation at the Prestwood Mine, including re-establishment of mains power. Once rehabilitation is well advanced, in Q2, all lower levels of the mine will be mapped and sampled, and underground drilling to test the extent of the parallel and cross-cutting structures will commence.

ASX ANNOUNCEMENT 28 April 2014
The Company is confident it will subsequently be possible to quickly bring Prestwood into production as its first high-grade gold mine. There are toll treating possibilities within 25km, which may facilitate near term production, without having to commit capital to building a reduction facility.
The evidence of mineralised parallels, cross shears and the monzonite contact is very exciting, particularly when considered with the geological model that has been refined by ground magentics. Future surface work will consist of Induced Polarisation surveys to define sub-outcropping disseminated halos, followed by a short hole RAB drilling program to identify broader disseminated targets. Tenders are currently being considered for this work.

Figure 3: Positions of Current and Former Producers in the Gwanda Greenstone Belt .
A number of the mines lie at the contact zone of the monzonite intrusions and greenstones, which forms a highly prospective rheological contrast. The known strike extent of the monzonites is almost 6km.

JORC TABLE 1 Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques |
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 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. |
• The samples were percussion chips generated from a Super Rock 5000 rig, using a double tube reverse circulation technique. • 3kg Samples were collected every metre in triplicate, in addition to a smaller sample retained for reference and logging. |

| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| 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). |
• A Superrock 5000 double tube RC rig was used with a 700cfm Doosan (Ingersoll Rand) 2013 compressor. 6m rods were used, and the hole air blasted to allow sample recovery via a cyclone every 1m. |
| 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. |
• Chip samples were bagged directly from the cyclone, and immediately weighed, then riffle split. • Material seems largely homogenous, and no relationship has been detected between grain size and assayed grade. |
| 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. |
• Chip samples have been geologically logged at 1m intervals, with data recorded in spreadsheet format using standardized codes. Sample weight, moisture content, lithologies, texture, structure, induration, alteration, oxidation and mineralisation were recorded. • The work is undertaken according to Prospect Resources’ standard procedures and practices, overseen by the CP. Prospect Resources believes that the level of detail and quality of the work is appropriate to support the current and any future 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. |
• Initial screening of samples was undertaken at the Farvic Laboratory, using Atomic Absorption, after DIBK dissolution, with a lower limit of detection of 0.03ppm. All samples were however subsequently also assayed by fire assay, at accredited laboratory, Antech in KweKwe, Zimbabwe. • Standards and duplicates as described above were inserted blind into the batch within the same numbered sequence, prior to their submission to Antech. • Umpire checking is then undertaken at ALS Johannesburg, another accredited laboratory. |

The drilling grid lies specifically within claim numbers ; GA36972 and GA33269 • These claims have recently been inspected by the local Department of Mines (Gwanda), and copies of these inspection certificates are available from Prospect Resources or the Department on request. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties |
• No known previous exploration has been undertaken. Channel chip sampling was however undertaken at the old underground workings in the late‘40s. The results are recorded on surviving mine plans. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Steeply dipping shear and vein hosted lode gold deposits, associated with pyrite, pyrrhotite and arsenopyrite. These structures lie at the contact between meta- basalts and monzonite intrusions of the Gwanda Greenstone Belt, in a similar fashion to the neighbouring producing Farvic Mine. |
| 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 collaro 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 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. |

| Dataaggregation 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. |
• A statistically determined cut-off grade will be applied once a resource is declared on completion of the programme. |
|---|---|---|
| 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 widths specified are down hole widths, though the holes were angled to intersect the main reef approximately perpendicularly. The dip of the reef was fairly confidently estimated due to the proximity of the accessible Prestwood Main Shaft, and old underground plans. |
| 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. |

| 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, all results have been reported. |
| 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. |
• The drilling grid lies within an approximately 1.2km x 700m grid that was mapped in detail, and surveyed by ground magnetics. This survey was undertaken by independent consultant 3D Exploration of Gaborone, Botswana. • The results correlated well with the 4 year old airborne data, and geological observations. Areas underlain by greenstones and monzonites were well delineated In addition the pervasive SW-NE shearing, with a more subtle SE-NW trends were identified. • The geological setting is very similar to that at the adjacent Farvic mine, where Prospect Resource geologists have been providing technical input for a number of years. |
| 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 |
• The company intends to complete the pumping out of the old Main Shaft, and then based on these positive results to begin extending the old 2 – 4 levels. In addition the shaft will be deepened to the now-drilled 5 level. • Further geophysics; IP and ground penetrating radar is planned in the vicinity, to target parallel structures, prior to a shirt hole drilling programme in Q3. |

Section 3 Estimation and Reporting of Mineral Resources (Criteria listed in section 1, and where relevant in section 2, also apply to this section.)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Database integrity |
Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used |
• All data had been input by Prospect Resources Database Manager, and verified by the CP. _• _ |
| Site visits | Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. |
• The CP visited the drill numerous times daily during the programme. _• _ |
| Geological interpretation |
Confidence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit. Nature of the data used and of any assumptions made. The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology |
• The geological setting is very similar to the nearby Farvic Mine, where all the Prospect Resources Geologists, including the CP have worked. • The reefs are formed in shears at the contact between the greenstones (metabasalts) and monzonites, due to rheological contrasts. • Airborne radiometrics and magnetics, coupled with the recently completed ground magnetic survey has seemingly delineated sub-outcropping areas of monzonite (magnetic, with high background radiation) against the non-magnetic greenstones. • The best developed ore deposits appear to be formed at this lithological contact, where cut by SW- NE shears, and occasional conjugate fractures. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• The drilling has increased the known strike length of the Prestwood Main Reef to over 75m and equally has shown that down dip, it is open ended below 195m depth (theoretical 6 level). |
