1. INTRODUCTION
Exploration Permit for Minerals (EPM10652) is located about 40 kms east of Charters Towers and 10 kms west of Ravenswood, in North Queensland (Drawing No. 70011).
The permit is one of a group of 14 tenements in the Ravenswood district over which exploration was managed and conducted by MIM Exploration Pty Ltd (MIMEX) for the MIM Holdings Ltd group of companies until December 2001, when MIMEX transferred management of the Ravenswood EPM’s to Carpentaria Gold Pty Ltd. Carpentaria Gold Pty Ltd which operates and manages the Ravenswood Goldmines.
The project area is being explored for sub-volcanic breccia deposits (Mount Wright and Mount Leyshon types) and mesothermal style gold mineralisation (Ravenswood, Sarsfield type). Mineralisation is known to occur at a number of locations within the tenements, within and adjacent to alteration zones and regional structural features.
Under the previous management of MIMEX, a range of exploration works have been carried out over a period of over 20 years. This area of exploration lies mainly within a radius of 30kms from the Ravenswood Goldmine. This wider area has been scrutinised mainly by using stream sediment BCL gold geochemistry together with aeromagnetic survey data to search for possible signatures of significant gold mineralisation. Within a 5km radius of Ravenswood and Mt Wright 200m x 200m BCL soil geochemistry has been used together with ground magnetics and electrical geophysics (MIMDAS & CSAMT). Intensive RC and diamond drilling programs have been carried out in and around Ravenswood and Mt Wright with minor drilling on a number of prospects in the surrounding areas.
Carpentaria Gold operating on a tight exploration budget and with limited manpower and logistical resources has been relatively restricted to drilling of advanced prospects, with a view to providing mill-feed and upgrading existing resources.
Exploration over the 17sub-blocks relinquished from this EPM includes an RC drilling program at Spider Gully Prospect.
2. LOCATION AND ACCESS
EPM10652 “Natalie” consists of 5 separate groups of tenements to the west, northwest and southwest of Ravenswood. Access to the Northern groups of the permit area is via the Flinders Highway between Townsville and Mingela then via the sealed Burdekin Falls dam road to Ravenswood. The southern groups of the permit are accessed from the graded Broughton Road via Charters Towers. Station tracks provide general access throughout the area. The Burdekin River separates the northern and southern blocks of the tenement.

Natalie Rock-Chip GeochemistryIn checking the 13 geophysical targets rock chip sampling was conducted where appropriate. Brief descriptions of the targets and their field character are presented the table above. Results of the ground checks and rock chip sampling were encouraging, with three of the targets (J03, J04 and J09) considered prospective.
A total of 6 rock-chip samples (TA85901-906) were taken whilst field-checking these targets. Four samples (TA85901, TA85902, TA85903 and TA85905) were at or below detection Au (0.001ppm). However 2 samples taken of at Target J09 were anomalous in Au and several other pathfinder elements. Sample TA85904 of Fe- ox-Mn-Ox stained low temperature silica vein with boxwork textures and moderate sericite selvedge alteration returned the highest Au assay of 0.442ppm, 185ppm Cu and 9ppm Mo. Sample TA85905 of buck-quartz with cross-cutting micro-shears featuring Fe-ox staining and malachite-azurite veins assayed 0.168ppm Au, 9260ppm Cu, 966ppm Zn, 24ppm Bi, 874ppm As and 24 ppm Mo. Both TA85905 and TA85906 were sampled from veins within a regional structure striking 045AMG. Target J03 has been further investigated, and named the Spider Gully Prospect.

Spider Gully Prospect
GeologyGeology and regolith mapping were conducted at 1:5,000 scale over the area comprising the Spider Gully Prospect .
The main area of outcrop comprises a variably light pink to brick-red, m-grained, biotite granodiorite with multiple quartz veins. Minor aplite dykes crop out in the immediate prospect area, which appear to strike approximately NW. Relatively thick quartz vein float occurs over much of the subcropping area.
July EPM 10652
Prospect-scale mapping suggests two different styles of quartz vein mineralisation as well as weak, patchy disseminated mineralisation occor within the host granodiorite. Abundant thin 1-3cm wide massive quartz veins crop out over at least 400m x 800m, which invariably have weak to intense secondary Cu mineralisation (mostly as malachite) adjacent to the veins within the host rock. Minor chalcopyrite and pyrite is present in a number of the veins at the surface. The second style of quartz vein that crops out in the area are typically 10-30cm wide, which have vuggy median cavities partially filled with Fe-oxide, sulphide boxworks molybdenite ferrimolybdite malachite chalcocite. Alteration appears to comprise primarily weak to intense vein-selvage sericitisation, with less-well developed pink-red staining (hematite dusting). Both vein styles are flat lying (10-30 degrees) and exhibit an overall south-dip. Although vein orientations are centred on or about an E-W axis, there are two distinct orientations with veins striking both NW and NE (parallel to structures evident in the magnetics). Veins, in most cases, are several metres apart.
Residual soil persists for only a short distance away from the outcropping area, which then grades into colluvium that forms low rolling ridges and spurs. Two large creeks drain the surrounding area, which typically have alluvial flats bordering them. Numerous 1st order streams drain the immediate prospect area with only small catchment areas.
Spider Gully Prospect Stream Seds
A total of 19 stream sediment samples were collected from creeks draining the Spider Gully Prospect (TB5618-TB5636). Samples were assayed by ALS Townsville using methods PM226 for Au, and IC581 for Cu, Pb, Zn, Ag, As, Mo, Bi, Sb and Fe. AMG co-ordinates and assays are given in the appendices. The sample locations are shown on Drawing No. 55240.
Data collected from open file suggests that there have previously been a number of stream sediment samples collected from the larger streams in the area surrounding Spider Gully. These assay values do not indicate any anomalism (in either Au, Cu or Ag), therefore MIM Exploration conducted a small stream sediment survey to assess whether the drainage was carrying metals from the prospect. Several of the previously sampled sites were re-sampled, as well as a number of smaller creeks draining into these. Most of the re-sampled sites in the larger streams repeated quite well and did not indicate any anomalism, however 1st order streams within 500m of the main outcropping zone are strongly anomalous in Cu (maximum 279ppm).
Spider Gully Prospect Soils
As follow up to the positive mapping and rock chip sampling at Spider Gully Prospect, a broadly spaced soil sampling survey was conducted over an area approximately 3.8 x 2.6km, centred on the outcropping portion of the prospect. A total of 317 samples were collected (TB5301-TB5617) using –80# and BCL
July EPM 10652
sampling methods. Samples were analysed at ALS Brisbane and Townsville for Au, Cu, Pb, Zn, Ag, As, Mo, Bi, Sb, Te, Tl, Hg, Fe, and Mn using methods PM229, IC581 and ICMS200. Co-ordinates and assay values are given in the appendices . The sample locations are shown in Drawing No. 55241.
A significant Cu, Mo, Ag and Au anomaly has been defined over the central portion of the survey area. Cu and Ag values in particular, are highly elevated, with Cu values up to 1330ppm (background 16ppm) and Ag up to 420ppb (background 20ppb). Au (maximum 17ppb) and Mo (maximum 9ppm) values are only weakly elevated, however they exhibit a very strong correlation with Cu and Ag. Mo doesn’t appear to be stable in the current regolith environment, despite the fact that there is abundant Mo in many of the outcropping quartz veins. The regolith over the survey area ranges from residual soils in the outcropping areas, transitional into colluvium and recent alluvial sands adjacent to the dominant drainage.
A +220ppm Cu anomaly covers an area approximately 1200m x 600m (centred around 456500mE, 7761600mN), which has a pronounced NW-SE trend. An area of +600ppm Cu occurs over 400m x 200m in the central portion of the anomaly.Strongly elevated Cu-Ag and weakly elevated Mo-Au occurs over approximately 2300m x 1000m, including areas with cover up to 3-4m thick, which has a very tight spatial association with a pronounced NW-trending magnetic-low (the original regional geophysical target, J03).
Spider Gully Prospect rock Chips
A total of 24 rock chip samples (TB01732-TB01738, TB01742-TB01751, TB01754- TB01760) were taken. Samples were assayed by ALS Townsville, by method PM209 for Au and IC581 for Cu, Pb, Zn, Ag, As, Bi, Mo, S, Sb. Twenty of the rock chip samples were collected from Spider Gully Prospect, which mainly comprised samples of quartz vein material and/or altered granodiorite. The majority of the samples contained visible Cu and/or Mo mineralisation. Most of these samples exhibit highly elevated geochemistry, with Cu to a maximum of 19.3% and Mo to 1.9% in samples with obvious mineralisation. Au values are generally low, with a maximum of 0.26 g/t recorded, and Ag values reached a maximum of 48 g/t.
Samples TB01754 (quartz vein) and TB01755 (sericite-altered granodiorite breccia) from target J09 both exhibit anomalous Cu (0.42% and 2.53% respectively), with TB01754 also recording elevated Mo (839ppm). Sample TB01738 (galena-bearing Fe oxide stained quartz vein) from target J04 shows strongly anomalous Pb (4.25%), and elevated Cu and Mo. Locations, assays, and descriptions for the regional rock chip samples are given in the appendices, and the sample locations are shown on Drawing No. 55242.
Spider Gully Drilling
Four RC percussion drillholes (SGP1-4) were completed at Spider Gully Prospect, for a total of 982m. Details of the holes are included in the table below .
July EPM 10652
Samples from drill hole SGP1 were analysed for the standard suite of elements as above, with the addition of Sb, Ca, Mg, Na, K, Al, Ni, and Co by method IC587.
Drill holes SGP1-3 all targeted a zone of flat southerly dipping quartz veins with anomalous Cu-Mo-AgAu hosted by m-grained, equigranular, biotite granodiorite . SGP4 was targeted at a discrete NW-trending magnetic low, thought to be one of the main controlling structures to mineralisation. A brief summary of the geology intersected in each of the drill holes is given below.

SGP10-95m Consists of zones of moderate-strong sericite alteration associated with widely spaced Qz veins (10-15m apart). These zones typically have weak (up to 0.5%) chalcopyrite and molybdenite mineralisation. Away from the zones of Qz veining the host granodiorite typically exhibits weak-strong pervasive hematite dusting with weak disseminated chalcopyrite and molybdenite mineralisation throughout.95-116m Zone of intense Qz veining in first 6m with associated very intense, texturally destructive yellow sericite alteration with accompanying chalcopyrite (up to 2%) and molybdenite (up to 5%) mineralisation. Minor Qz veins from 101-116m with strong-intense sericite and disseminated chalcopyrite and molybdenite.116-250m Distinct change to homogeneous m-grained, biotite granodiorite with patches of moderate-intense pervasive hematite dusting. The entire interval exhibits weakly disseminated chalcopyrite and molybdenite mineralisation with no apparent Qz veining.
SGP20-70m Consists of minor zones of Qz veining with weak-strong sericite alteration and weak (<0.5%) chalcopyrite and minor molybdenite. Host granodiorite exhibits pervasive moderate-strong hematite dusting away from the zones of sericite alteration.70-99m Moderate-intense, texturally destructive yellow sericite alteration adjacent to central 10m interval of f-m-grained aplitic? dyke. Entire 29m interval contains weak to very strong (0.2-5%) molybdenite with accompanying variably weak- moderate (0.2-3%) chalcopyrite mineralisation. Minor Qz veining occurs within the best mineralised zones.99-195m Patchy fracture-controlled, sericite alteration, host granodiorite exhibits variable pervasive weak-intense hematite dusting with weak disseminated chalcopyrite and molybdenite mineralisation.195-196m 0.5m wide Qz vein with 15-20% chalcopyrite196-219m Zone of weak sericite alteration with associated weak chalcopyrite and molybdenite (0.2-0.5%).219-250m Granodiorite with no visible sulphides, moderate-strong pervasive hematite dusting occurs throughout.
July EPM 10652
SGP3Patchy sericite + chlorite alteration throughout, mostly associated with calcite veins. Away from the sericite + chlorite altered zones, the granodiorite typically exhibits variably weak-intense pervasive hematite dusting. Mineralisation is patchy and typically very weak, comprising minor disseminated chalcopyrite + molybdenite pyrite. Up to 2% chalcopyrite was intersected over a single metre @ 36-37m.
SGP4Very weak to weak, patchy disseminated chalcopyrite molybdenite mineralisation occurs throughout most of the hole, typically within moderate-strongly hematite dusted granodiorite. Patchy sericite + chlorite alteration between 40-185m appears to be associated with calcite veining, as it does at 185-205m where increased calcite veining has produced moderate-intense sericite + chlorite alteration, with a distinct lack of sulphides. The calcite veins and attendant sericite + chlorite alteration are clearly late (postdate mineralisation), and have been magnetite destructive.
Based on the information gained from the drill cuttings, it appears there are three main styles of alteration and two distinct mineralisation phases/styles. Early, possibly orthomagmatic, sulphides occur throughout the host granodiorite, manifest as weakly disseminated chalcopyrite and molybdenite pyrite. The only early alteration? spatially associated with these sulphides is pervasive hematite dusting. Overprinting this phase are widely-spaced, moderate-high grade molybdenite and chalcopyrite-bearing Qz veins (plus aplite dyke) with associated moderate-intense sericite alteration (mostly observed in holes SGP1 & 2). Late stage sericite + chlorite alteration appears to be associated with the emplacement of a phase of structurally controlled carbonate veins. It is likely that the zone of low magnetic intensity, along the NW trending structure through the prospect area, is related to this late phase of carbonate veining.
Assays have been received, which confirms the system comprises individual veins (2cm to >0.5m) that host moderate-grade Cu-Mo mineralisation, with weak disseminated Cu-Mo mineralisation in the host rock in the zones between veins.Vein density appears to be insufficient to ‘upgrade’ Cu-Mo values required for a bulk-tonnage low-moderate grade deposit. Details of drillhole intersections are given below.

SUMMARY GEOLOGY LOG
From To Geology Assay0m 1m Residual soil cover1m 95m M-grained, biotite granodiorite: Consists of zones of moderate-
strong sericite alteration associated with widely spaced Qz veins (10-15m apart). Qz veins typically have weak (up to 0.5%) chalcopyrite mineralisation and stronger molybdenite mineralisation (up to 5% reported). Minor malachite is associated with Qz veins in the oxidised zone. Away from the zones of Qz veining the host granodiorite typically exhibits weak-strong pervasive hematite dusting with weaklydisseminated chalcopyrite and molybdenite mineralisation throughout.
95m 116m M-grained, biotite granodiorite: Zone of intense Qz veining in first 6m with associated very intense, texturally destructive yellow sericite alteration with accompanying chalcopyrite (up to 2%) and molybdenite (up to 5%) mineralisation. Minor Qz veins from 101-116m with strong- intense sericite alteration and disseminated chalcopyrite andmolybdenite. Possible aplite dyke from 110-116m.
116m 250m Homogeneous m-grained, biotite granodiorite with patches of moderate-intense pervasive hematite dusting. The entire interval exhibits weakly disseminated chalcopyrite and molybdenitemineralisation with no apparent Qz veining.

SUMMARY GEOLOGY LOG
From To Geology Assay0m 2m Soil, proximal colluvium2m 70m M-grained, biotite granodiorite: Consists of minor zones of Qz
veining with weak-strong sericite alteration and weak (<0.5%) chalcopyrite and minor molybdenite mineralisation. Host granodiorite exhibits pervasive moderate-strong hematite dusting away from the zones of sericite alteration.
70m 99m Moderate-intense, texturally destructive yellow sericite alteration of host granodiorite adjacent to central 10m interval of f-m-grained aplitic? dyke. Entire 29m interval contains weak to very strong (0.2- 5%) molybdenite with accompanying variably weak-moderate (0.2-3%) chalcopyrite mineralisation. Qz veining occurs within the best mineralised zones.
99m 195m M-grained, biotite granodiorite: Patchy fracture-controlled, sericite alteration, variable pervasive weak-intense hematite dusting throughout granodiorite with weak disseminated chalcopyrite and molybdenite mineralisation.
195m 196m 0.5m wide Qz vein with 15-20% chalcopyrite.196m 219m M-grained, biotite granodiorite: Zone of weak sericite alteration
withassociated weak chalcopyrite and molybdenite (0.2-0.5%).
219m 232m M-grained, biotite grandiorite: zone of intense chlorite + sericite alteration asociated with calcite veining. Veining and alteration isclearly late and postdates mineralisation.
232m 250m M-grained, biotite granodiorite: no visible sulphides, moderate-strongpervasive hematite dusting occurs throughout.

Drill Site Rehabilitation Report
JAN 2002
Spider Gully Prospect
EPM 10652 “Natalie”
July EPM 10652
Drilling
A four hole RC percussion drilling programme (SGP1-4) was undertaken by MIM Exploration Pty Ltd in April-May 2001 by Drilltorque drilling using a Schramm drill rig. The drilling was undertaken at the Spider Gully prospect, which is on EPM 10652 “Natalie”.
Rehabilitation
These drill sites had PVC collars cut off below ground and plugged, and were rehabilitated by MIM Exploration Pty Ltd. An inspection carried out in January 2002 found the grass vegetation re-establishing itself and no erosion (sites flat). Further seeding was carried out prior to the wet season, and the sites will not require any further monitoring. The table below shows the drill holes and collar positions. Attached is a photographic record of the rehabilitated sites.
