2 Exploration Gilgunnia Project: Copper, Silver, Gold, Lead, Zinc; Western NSW (PEX 100%, CBH earning up to 50%). Targets: Cobar-style polymetallic mineralisation; Volcanogenic Massive Sulphide mineralisation. Exploration During the quarter, drilling and exploration re-commenced at the Mallee Bull copper-polymetallic discovery, 100km south of Cobar in NSW. As announced in the previous quarter, Mallee Bull is subject to an $8.3m farm-in agreement with CBH Resources Ltd, whereby CBH has the right to earn an interest of up to 50% in the project over a three-year period. Importantly, Peel remains operator during the farm-in period. Diamond Drilling Drilling at Mallee Bull was planned to comprise about 4,500m of diamond drilling targeting downdip/plunge mineralisation and commenced in mid-july. Subsequent to the end of the September quarter, drilling of the last drillhole (MBDD009) was being undertaken. Peel is highly encouraged with results returned to date with all drillholes completed returning significant mineralisation. In early September, assay results subsequently showed MBDD001, drilled at the southern extent of Mallee Bull, had returned 5m at 0.85% Cu, 9 g/t Ag, 0.62 g/t Au and 248 g/t Co from 431m and 3m at 1.07% Cu, 30 g/t Ag, 2.09 g/t Au, and 49 g/t Co from 447m. MBDD002 (80m north of MBDD001) intersected the broadest width of mineralisation encountered to date at Mallee Bull. A cumulative intercept of 72m at 3.51% CuEq* (2.11% Cu, 41 g/t Ag, 1.13 g/t Au, 384 g/t Co) comprising two broad zones of mineralisation a massive sulphide zone of 41m at 1.71% Cu, 33 g/t Ag, 1.84 g/t Au, 616 g/t Co from 363m and a stringer/breccia sulphide zone of 31m at 2.65% Cu, 51 g/t Ag, 0.18 g/t Au, 78 g/t Co from 415m was returned.

3 MBDD003 (140m north of MBDD001) returned a cumulative intercept of 58m at 3.15% CuEq* (2.36% Cu, 44 g/t Ag, 0.30 g/t Au, 97 g/t Co) comprising four zones of mineralisation 10m at 1.12% Cu, 47 g/t Ag, 0.95 g/t Au, 377 g/t Co from 367m; 12m at 1.58% Cu, 39 g/t Ag, 0.14 g/t Au, 39 g/t Co from 386m; 14m at 1.92% Cu, 56 g/t Ag, 0.30 g/t Au, 37 g/t Co from 409m; and 22m at 3.62% Cu, 38 g/t Ag, 0.09 g/t Au, 40 g/t Co from 444m. MBDD004 (40m north of MBDD001) returned a thick zone of massive and stringer sulphide mineralisation comprising 42m at 1.99% CuEq* (1.01% Cu, 23 g/t Ag, 0.91 g/t Au, 250 g/t Co) from 356m. MBDD005 (40m north of MDD001) was designed to test down dip of MBDD004 however, swung substantially off-section to the south. Several moderate zones of mineralisation were returned comprising 5m at 1.75% Cu, 31 g/t Ag, 0.21 g/t Au, 110 g/t Co from 414m and 5m at 1.44% Cu, 68 g/t Ag, 0.34 g/t Au, 46 g/t Co from 421m. Long Section MBDD006 (100m north of MBDD001) returned a cumulative intercept of 51m at 2.19% CuEq* (1.45% Cu, 26 g/t Ag, 0.54 g/t Au, 162 g/t Co) comprising three zones of mineralisation 7m at 1.09% Cu, 29 g/t Ag, 1.74 g/t Au, 520 g/t Co from 396m; 13m at 1.91% Cu, 31 g/t Ag, 0.12 g/t Au, 44 g/t Co from 405m; and 31m at 1.90% 1.61% Cu, 13 g/t Ag, 0.17 g/t Au, 52 g/t Co from 444m. MBDD007 (60m north of MBDD001) designed for downhole EM geophysics (see page 5) and as a platform for wedge drilling intersected strong alteration from ~580m below surface with moderate mineralisation returned 4 m at 26 g/t Ag, 0.11 g/t Au, 0.98% Pb, 1.58% Zn from 584m; 4m at 75 g/t Ag, 0.91 g/t Au, 1.82% Pb from 617m; and 1.55% Cu, 10 g/t Ag, 0.14 g/t Au, 132 g/t Co from 647m. Peel Mining Limited Quarterly Report September

4 MBDD008 (140m north of MBDD001), designed to test down dip from MBDD003, intersected 35m of semimassive-to-massive sulphides from 374m followed by ~60m of weak-to-moderate stringer/breccia mineralisation from 442m. Assay results for MBDD008 remain outstanding at the time of reporting. MBDD009 (drilled subsequent to end of quarter) was designed to test a very strong conductor centred at ~500m below surface as defined by a recently completed downhole EM survey (see more below), and at the time of reporting was still underway. Drill Location and Geology Plan The true width of mineralisation intersected to date in Phase 2 drilling is estimated to be about 55-65% of the downhole intervals, except for MBDD007 where the true-width is estimated to be about 40% of the downhole intervals. Drilling completed to date indicates that high-grade copper-dominant polymetallic sulphide mineralisation at Mallee Bull has a strike length of ~120m, comes to within 150m of surface, and now extends to at least 450m below surface and is open in multiple directions including at depth. The styles of mineralisation present at Mallee Bull are similar to those found elsewhere in the Cobar district including at the world-class CSA mine, one of Australia s highest grade copper mines. Cobarstyle deposits are typically short in strike length but long in the vertical plane. RAB Drilling During the quarter it was reported that several shallow RAB drillholes completed as part of the current exploration programme, had returned significant mineralisation. This RAB drilling, designed to test for oxide or supergene mineralisation, confirms that the Mallee Bull deposit comes to surface, albeit within a heavily leached regolith. Better results to date include: MBRAB g/t Au, 78 g/t Ag, 0.95% Cu, 5.20% Pb and 1.64% Zn from 42m. MBRAB004 2m at 0.1 g/t Au, 40 g/t Ag, 0.43% Cu, 1.85% Pb, 2.16% Zn from 78m; and 1m at 0.08 g/t Au, 28 g/t Ag, 0.1% Cu, 1.15% Pb, 1.32% Zn from 83m. MBRAB008 4m at 0.25 g/t Au, 4 g/t Ag, 1.80% Pb from 37m; and 4m at 0.15 g/t Au, 62 g/t Ag, 0.23% Pb, 0.38% Zn from 47m. Peel Mining Limited Quarterly Report September

5 Geophysics During the quarter, downhole EM surveying was completed in drillholes MBDD001 and MBDD007. Both holes produced extremely strong EM responses that are consistent with each other and with the known mineralised horizon at Mallee Bull. The DHEM survey was completed by Outer Rim Exploration Pty Ltd and independently reviewed and modelled by specialist geophysical consultants Newexco Services Pty Ltd and Arctan Services Pty Ltd. MBDD001 was drilled at the southern end of the Mallee Bull prospect to ~490m depth at -80 degrees towards the east. A strong inhole response was recorded at ~440m downhole depth that merged into a much stronger offhole response at later times, centred at a similar downhole depth. The time constant for the inhole part of this (these) response(s) is about 10 milliseconds while the time constant for the offhole part is about 60 milliseconds, implying that the conducting horizon becomes considerably more conductive and/or thicker away from the drillhole. MBDD007 was drilled vertically, deviating to -85 degrees at its maximum depth of ~770m. This hole was drilled at an acute angle to the prospective horizon, which dips at around 70 degrees to the west, and intersected the Shume Formation, host to mineralisation at Mallee Bull, at 570m downhole with strong alteration however only relatively minor mineralisation was returned (minor semimassive and stringer pyrrhotite with lesser galena, sphalerite, arsenopyrite and chalcopyrite). MBDD007 recorded a broad, late time offhole response centred at ~580m downhole depth. A narrower, offhole response is centred at 620 metres downhole, which is approximately the downhole location of minor mineralisation intersected in the hole. The time constant for the late time offhole response is 60 milliseconds. This is an extraordinarily high value for the Cobar region, indicating a very conducting and/or thick conducting zone. The similarity of this time constant with the very late time values calculated in MBDD001 implies that these are from the same source. Modelling of the downhole EM data for MBDD001 and MBDD007 shows an extremely strong offhole conductor response to the east of MBDD007, i.e. updip, and with a plunge to the north. The inhole part of the response in MBDD001 is likely to be sourced by a part of this zone towards its southern edge while the mineralised intersection in MBDD007 is close to but below the conducting zone. Interestingly, the northerly plunging geometry of the modelled conductor plates is consistent with 3D inversion modelling of total magnetic intensity (TMI) data collected during the VTEM survey of the 4- Mile area. 3D TMI inversion modelling shows the magnetic anomaly associated with the Mallee Bull prospect as a northerly plunging, horn-like feature extending out of the core of the very large Butcher s Dog magnetic anomaly 1km north. In February 2012, Peel completed one deep drillhole targeting Butcher s Dog. Drillhole BDRCDD001 was drilled as a vertical hole, however deviated to -78 degrees at its maximum depth of 680m. No satisfactory explanation for the magnetic anomaly was observed from geological logging or downhole geophysics. Further investigation is required. Additionally during the quarter, a fixed-loop (surface) EM geophysical survey targeting prospective stratigraphy in close proximity to Mallee Bull was undertaken. No strong conductors were identified; however it is believed that the depth of penetration of the survey was likely impeded in places by the presence of conductive overburden. Future surface geophysics will test other methods for suitability. Peel Mining Limited Quarterly Report September

The 4-Mile goldfield comprises up to 60 shafts and workings spread over an area covering about 1,000m by 500m. Initial drilling resulted in the discovery of significant silver-lead-zinc mineralisation. Follow-up drilling completed in July/August 2011 intersected massive sulphides containing strong Cu-Ag-Au-Pb-Zn-Co mineralisation within a broad zone of deformation and alteration. The Mallee Bull prospect is located less than 10 kilometres east of the May Day gold-silver-lead-zinc deposit (ML1361), where drilling in 2010 confirmed the down-dip continuation of mineralisation to more than 200m below surface. In May 2012, CBH Resources farmed-in to Mallee Bull whereby CBH has the right to earn an interest of up to 50% in the project over a three-year period through an $8.33m spend. Peel remains responsible for exploration activities through this period. CBH Resources is an Australian-based mineral resources company producing zinc, lead and silver from the Endeavour Mine north of Cobar, and the Rasp mine in Broken Hill. The company, which is 100%-owned by Tokyo Stock Exchangelisted Toho Zinc, recently opened the Rasp underground zinc, lead and silver mine at Broken Hill.

7 Cobar Superbasin Project: Copper, Silver, Gold, Lead, Zinc; Western NSW (PEX 100%). Targets: Cobar-style polymetallic mineralisation; Volcanogenic Massive Sulphide mineralisation. During the quarter, Peel continued to add to its strategic position within the Cobar Superbasin by pegging additional tenure. In total, Peel now has nine new licences covering in excess of 1,650 km 2. Peel also completed a 350 line kilometre HeliTEM airborne EM survey covering part of EL7519 Gilgunnia South. Final results remain outstanding at the time of reporting. Subsequent to the quarter, Peel reported that EL Mundoe - covering 270 km 2 of highly prospective stratigraphy within the Rast Trough region, the southern extension of the Cobar Superbasin, had been granted. Mundoe is located about 90 km west of Condoblin in NSW, or about 50 km south of Mallee Bull. EL7976 is centred on the Mundoe prospect, which is defined by a 2km long multi-element geochemical anomaly, coincident geophysical anomalies, and encouraging historic drill results. Mundoe was first identified in the 1970s as a bulls-eye magnetic anomaly. Follow-up exploration in early 1980s included geological mapping, RAB drilling, IP and gravity geophysical surveys, and a single diamond drillhole where a best result of 2.90% Zn, 0.87% Pb, 30 g/t Ag and 0.4 g/t Au from 88m was returned. Exploration in the 1990s culminated in the discovery of strong copper-silver mineralisation in three separate drillholes covering 400m strike. Better results from this drilling included: 6m at 1.66% Cu, 103 g/t Ag from 111m in MURP-2; 3m at 122 /t Ag, 0.3 g/t Au from 42m and 6m at 0.42% Cu, 14 g/t Ag from 69m in MURP-3; and 12m at 1.09% Cu, 60 g/t Ag in MURP-4. Mundoe prospect geochemistry vs drilling plan A follow-up drilling programme in 2005 failed to return mineralisation. However, a data review by Peel indicates that mineralisation is likely to be dipping to the east presenting a significant possibility that this drilling (drilled from west to east) inadequately tested the previously intersected mineralisation. Accordingly, an RC drilling programme is planned for late November, subject to receiving regulatory approvals. Peel Mining Limited Quarterly Report September

10 Information regarding drilling/assaying data 1. Drilling was completed as HQ or NQ diamond core or RAB. 2. Sample recoveries were considered adequate for all samples. 3. Drillcore/chips have been logged in detail based on lithology, mineralisation, and alteration. 4. Samples for analysis were collected by sawing core in half; or by hand-spearing for RAB. 5. Samples were submitted as 1m or 4m composite half-core intervals; or1m or 4m composite chip samples. 6. Samples were analysed at ALS Chemex utilising methods: Au AA25 for Au (fire assay); ME ICP41/61 for multi-element including Ag, Cu, Pb, Zn; Ag-OG46/62 for >100 g/t Ag; Cu-OG46/62 for >1% Cu; Pb-OG46/62 for >1% Pb; and Zn-OG46/62 for >1% Zn. 7. Drillhole collars were surveyed by DGPS (GDA94) and downhole gyroscopic surveys were run continuously in diamond drillholes. * Copper Equivalent calculation explanation: The copper equivalent (CuEq) calculation represents the total metal value for each metal, multiplied by the conversion factor, summed and expressed in equivalent copper percentage. These results are exploration results only and no allowance is made for recovery losses that may occur should mining eventually result, nor metallurgical flowsheet considerations. The copper equivalent calculation is intended as an indicative value only. No metallurgical testwork has been completed to date however it is the Company s opinion that all the elements included in the copper equivalent calculation have a reasonable potential to be recovered. Copper equivalent conversion factors and long term price assumptions used follow: Copper Equivalent Formula (CuEq) = (Cu (ppm) x Ag (ppm) x Au (ppm) x Co (ppm) x 0.025)/0.0075; Price Assumptions Cu (US$7,500/t), Ag (US$30/oz), Au (US$1,500/oz), Co (US$25,000/t). Pb and Zn have not been used in copper equivalent calculation.
