Exploration
Mallee Bull Project: Copper, Silver, Gold, Lead, Zinc; Western NSW (PEX 70%, CBH earning up to 50%).
Targets: Cobar-style polymetallic mineralisation; Volcanogenic Massive Sulphide mineralisation.
Drilling and exploration continued at the Mallee Bull copper-polymetallic discovery, 100km south of Cobar in NSW. As previously announced, Mallee Bull is subject to an $8.3m farm-in agreement with CBH Resources Ltd.
Prior to the quarter’s commencement, CBH Resources Limited proceeded with Stage 3 of the Mallee Bull farm-in agreement, which will see CBH spend a further $3.33 million on exploration at Mallee Bull to earn an additional 20%, taking CBH’s interest in Mallee Bull to 50%. Peel remains operator throughout the farm-in process. Exploration efforts at the Mallee Bull/Gilgunnia Project during the quarter have been focused on identifying potential new sources of mineralisation, supplementary to that already recognised at Mallee Bull. Promising results have been received with drilling continuing at the time of reporting.
Recent activities at the Mallee Bull/Gilgunnia Project have comprised diamond and RAB drilling, various surface and downhole geophysical surveys, mineralogical and metallurgical studies and the purchase of part of Wirchilleba Station. See below for further information.
BDDD001 Drillhole (Butcher’s Dog) Summary
Drillhole BDDD001 was designed to test a strong DHEM offhole conductor recognised at the Butcher’s Dog prospect north of Mallee Bull. Butcher’s Dog is defined by coincident magnetic and electromagnetic anomalies and is located under the axis of a regional scale anticline; proximal to a northeasterly trending shear/structure mapped at Mallee Bull and intercepted in MBDD011. Drillhole BDDD001 (1223.4m) intercepted a broad zone of disseminated and veinlet pyrrhotite mineralisation coincident with variable chlorite alteration and minor/trace chalcopyrite/galena and sphalerite; commencing at ~800m downhole and continuing to the drillholes end.
Sampling of the intervals 768-824m (56 samples) and 1038-1094m (56 samples) confirm anomalous precious and base metal values in these zones, consistent with observed alteration. Peak values for individual metres in these zones reached up to 0.54% Cu, 25 g/t Ag, 1.32 g/t Au, 0.51% Pb, and 1.92% Zn although most values are considerably lower than these results.
Follow-up DHEM surveying of BDDD001 indicates that the original DHEM target was intersected and was associated with a zone of abundant pyrrhotite mineralisation and chlorite alteration. The DHEM survey also identified a new, very strong offhole anomaly (~170 millisecond time constant) beneath BDDD001’s drillhole position. This anomaly is the strongest identified to date at the Mallee Bull/Butcher’s Dog project and is extremely high for the Cobar district and NSW in general.
Peel is very encouraged by the broad pyrrhotite and chlorite alteration, and coincident anomalous geochemistry returned in the drillhole and the presence of a very strong offhole conductor, and notes that disseminated pyrrhotite alteration halos can be associated with Cobar-style deposits and is a characteristic of Mallee bull. Follow-up work is planned.

RFDD001 Drillhole Summary
Drillhole RFDD001 (524.9m) was designed to test a coincident geochemical and stratigraphic target located on the eastern flank of the Mallee Bull anticline at the Rabbits Foot prospect, approximately 1km east of Mallee Bull. RFDD001 intercepted a thick zone of volcaniclastic material with variable pyrrhotite alteration and minor sphalerite and galena mineralisation. No significant assay results were returned.
MBDD012 Drillhole Summary
Drillhole MBDD012 (483.3m) was designed to test a moderate offhole DHEM anomaly identified at ~250m downhole in MBDD011. This anomaly is located in close proximity to significant lead-zinc-silver mineralisation observed over a 4m zone at ~390m in MBDD011. Galena, sphalerite and pyrite are known to be poor conductors and therefore any conductor in close proximity to this zone is potentially prospective.
MBDD012 intercepted a broad zone of variable, but generally weak, sphalerite-galena-pyrrhotitepyrite mineralisation occurring as veinlets from ~350m downhole to end-of-hole. This mineralisation is coincident with an increase in chlorite alteration. Assay results remain pending.
Follow-up DHEM surveying of MBDD012 indicates that the primary DHEM target remains untested and follow-up drilling targeting this anomaly is now underway.

MBDD013 and MBDD014 Drillhole Summaries
Drillholes MBDD013 (618.5m) and MBDD014 (799.9m) were recently completed targeting a newly identified geophysical anomaly generated from a magnetotelluric (MT) survey completed recently over the Mallee Bull and Butcher’s Dog prospect areas. Preliminary 2D modelling of the data identified a new anomaly located approximately 500m north of Mallee Bull. Drillholes MBDD013 and MBDD014 targeted this anomaly.
Both drillholes intercepted minor zones of variable, narrow, chalcopyrite-pyrrhotite-pyritearsenopyrite mineralisation similar in style to Mallee Bull “stringer” mineralisation with associated chlorite and silica-alteration. Peel is encouraged by the presence of this mineralisation. Assay results remain pending however are not expected to be economically significant. 3D modelling of the MT data also remains pending at the time of reporting.

Geophysics
A substantial programme of high-powered DHEM surveying utilising the DigiAtlantis receiver sensor has been completed at Mallee Bull and Butchers Dog recently, with additional surveys now underway. At Mallee Bull, DHEM has confirmed the general geometry of mineralisation encountered to date and has identified a strong offhole anomaly off MBDD010 for follow-up drill testing. As previously mentioned, DHEM of BDDD001 identified a new, very strong offhole anomaly beneath BDDD001’s drillhole position.

As previously mentioned, a magnetotelluric (MT) geophysical survey over the Mallee Bull and Butcher’s Dog prospect areas was also completed during the quarter. MT is a deep penetrating geophysical technique and has proven successful in detecting mineralisation at other Cobar Basin deposits (CSA and Elura mines). Preliminary 2D modelling of the data indicates that it successfully identified the Mallee Bull deposit, and also identified a new anomaly located approximately 500m north of Mallee Bull. Drillholes MBDD013 and MBDD014 targeted this anomaly. 3D modelling of the MT data also remains pending at the time of reporting.
A downhole magnetometric resistivity (MMR) geophysical survey was also completed in drillhole MBDD007 at Mallee Bull recently. Interpretation of the MMR data defined several conductive sources with data correlating well with DHEM modelling and the known Mallee Bull mineralisation as defined by drilling to date.
RAB Drilling
A programme of close-spaced angled rotary air blast (RAB) drilling was designed to cross the nose of the regional anticline near Mallee Bull targeting a magnetic anomaly located in this area and also to test near historic workings of the Four Mile gold field. The concept was to test for a shallow gold deposit using the nearby May Day gold mine as an analogue. May Day was originally worked as an underground copper-lead-zinc deposit before a shallow open cut gold operation was developed in the late 1990s. Generally low gold values were returned, however elevated base metals and pathfinder elements (as shown by portable XRF) were returned from several drillholes in close proximity to Mallee Bull. Followup work is planned.
Mallee Bull Mineralogy and Metallurgy
Two sets of core intervals from MBDD009W2W1 were sent to ALS Metallurgy in Burnie, Tasmania for initial flotation and particle mineralogy assessment. These sets represented the two dominant styles of mineralisation identified at Mallee Bull to date, i.e. Stringer Sulphide (or footwall lode) and the Massive Sulphide or (hangingwall lode). It is estimated that Stringer Sulphide mineralisation accounts for approximately 80% of all mineralisation intercepted to date whilst the Massive Sulphides account for the balance (20%).
Mineralogical assessments show two very different sulphide textures:
-
The Stringer Sulphide mineralisation contains only traces of pyrite or pyrrhotite and is some 85% volume non-sulphide gangue. Chalcopyrite shows excellent liberation from nonsulphides and the minor arsenopyrite present. At a grind p80=106um the 50% liberation size for chalcopyrite is 150um.
-
The Massive Sulphide mineralisation contains some 60% volume of pyrite and pyrrhotite (9:1 ratio) with around 35% volume of non-sulphide gangue. Minor presence of sphalerite and galena with chalcopyrite at around 1% of volume. The chalcopyrite shows strong association with pyrite to fine size. At a grind of p80=106um the chalcopyrite has a 50% liberation size of some 38um. (Above 38um Cp is <50% liberated and below 38um is >50% liberated.)
The Stringer Sulphide composite yielded excellent flotation results with concentrates of ~25% copper at a recovery between 90-95% returned from testwork. Further assessments to define an overall grade and recovery after cleaning are planned.

==> picture [156 x 69] intentionally omitted <==
The Massive Sulphide composite demonstrated reduced recovery and grade from roughing floats due largely to the strong association of pyrite and chalcopyrite. It is noted that Massive Sulphide mineralisation intercepted to date has shown considerable variability; from base-metal rich to basemetal poor; and the sample sent for testwork fits the latter category. Further assessments using stronger pyrite depression routines in roughing, and a variety of Massive Sulphide mineralisation are planned.
Peel is highly encouraged by these results, as they indicate that the bulk of mineralisation at Mallee Bull as defined by drilling to date (i.e. Stringer Sulphide) is potentially recoverable via simple metallurgical processes.
Wirchilleba Station Settlement
Peel recently completed the purchase of part of Wirchilleba Station in accordance with an option agreement executed in April 2012. Consideration for Western Lands Lease 3456, comprising 7,974 hectares, was $800,000. Peel purchased the property to secure long-term access and to assist in fasttracking future development at Mallee Bull.
Cobar Superbasin Project: Copper, Silver, Gold, Lead, Zinc; Western NSW (PEX 100%).
Targets: Cobar-style polymetallic mineralisation; Volcanogenic Massive Sulphide mineralisation.
Progress of Peel’s 100%-owned Cobar Superbasin project (including Sandy Creek) continued during the quarter with recent activities comprising diamond drilling, surface and downhole geophysical surveys, surface geochemical surveys and geological mapping. See below for further information.
PSCDD001 Drillhole (Sandy Creek) Summary
Drillhole PSCDD001 (639.2m) was completed during the quarter at the newly acquired Sandy Creek project targeting the namesake Sandy Creek prospect. Drillhole PSCDD001 was designed to test a strong DHEM offhole conductor and intersected several broad zones of mineralisation/alteration including: a 25m zone of disseminated pyrrhotite-dominant sulphides from 237m; and a 19m zone of variable pyrrhotite-dominant sulphides from 493m including a 4m zone of strong galena-dominant mineralisation averaging 48 g/t Ag, 0.50% Cu, 9.63% Pb, 1.1% Zn from 493m. The true width of these intercepts is estimated to be close to the downhole intercept.
Follow-up high-powered DHEM indicates that the anomaly remains open in multiple directions. PSCDD001 confirms the potential of Sandy Creek to host economic mineralisation and Peel notes that Sandy Creek bares many similarities to Mallee Bull at an early stage of exploration.
Other Cobar Superbasin Activity
An extensive review of historical data and preliminary field work has been undertaken on Peel’s broader 100%-owned Cobar Superbasin Project. This work has resulted in the definition of many prospects that warrant closer scrutiny. More than 7,000 multi-element portable XRF samples have been collected since exploration commenced with sampling interrupted due to an extended period of wet ground conditions over winter.
Eight prospects are now deemed as “priority one”; they are Bedooba, Tara, Tara 4, Burthong “S” Grid, Mundoe, A5 (Peel-4), Wirlong and Red Shaft. A priority one target has multiple characteristics similar to the known economic deposits of the Cobar Superbasin. Exploration of Peel’s Cobar Superbasin Project is continuing.
