1. INTRODUCTION

Exploration Permit for Minerals 14778 surrounds the town of Mingela, approximately 70 kilometres SSW of Townsville, North Queensland. The tenement was granted to Carpentaria Gold Pty Ltd on the 21st November 2005 by the Queensland Department of Minerals and Energy. EPM14778 includes the area previously covered by the following conditionally surrendered tenements:

EPM8936 “Birthday Hills”EPM8190 “Bluff”

Exploration activities for EPM8936 and EPM8190 were reported in their respective final reports (Green 2005a, 2005b).

Carpentaria Gold has been exploring the Ravenswood district since 1968 with mining beginning in Ravenswood in 1987 and at Mt Wright in 2006. Carpentaria Gold Pty Ltd was acquired by Resolute Mining Ltd in March 2004.

The Ravenswood area contains breccia style and stockwork vein targets within several prospective “corridors”. Targets include Mt Wright-style breccia pipes, high-grade, low tonnage Sunset-style veins, and low-grade, high tonnage Nolans-Sarsfield stockwork style vein deposits.

2. LOCATION AND ACCESS

EPM14778 lies within the Townsville SE55-14 and Charters Towers SF55-2 1:250000 sheet areas, and the Mingela (8258) and Ravenswood (8257) 1:100,000 sheet areas.

The tenement is located over the town of Mingela approximately 75 kilometres south- southeast of Townsville (Figure 1). Access to the relinquished area is via the sealed Flinders Highway from Townsville to Mingela, the sealed Burdekin Falls Dam Road or the unsealed Mingela-Dotswood Road. These roads and station tracks provide good access throughout the area except along the eastern edge where the rugged topography of the Leichhardt Range limits vehicle access.

4. REGIONAL GEOLOGY

EPM14778 is located within the Ravenswood Batholith, a major element of the Charters Towers Province of north east Queensland (Figure 3). The batholith is bounded to the south and south-east by the Cambrian-Ordovician Seventy Mile Range Group, to the north by the Devonian Burdekin Basin, to the east by the Carboniferous-Permian Coastal Range Igneous Complex and Quaternary sediments, and to the west by Tertiary cover sequences.

Figure 3: Regional geology of the eastern part of the Charters Towers Province, showing location of EPM14478 (shaded portion represent relinquished sub-blocks).

The Batholith is predominately comprised of early-mid Ordovician (490-463 Ma) hornblende and/or biotite bearing I-type granitoids of the Macrossan Igneous Association, commonly with a weakly developed fabric. This assemblage was intruded by I-type and lesser S-type granitoids of the Pama Igneous Association during the late Silurian to early Devonian (418-382 Ma). These intrusives show little strain, and are associated with mineralisation at Charters Towers and Hadleigh’s Castle (Kreuzer, 2005). Granitoids of the late Carboniferous to early Permian Kennedy Igneous Association are also represented within the batholith and are associated with mineralisation at Mt Leyshon, Ravenswood and Mt Wright (Perkins and Kennedy, 1998). Locally, “basement rocks” of the Neoproterozoic to Cambrian aged Charters Towers Metamorphics and Cambrian to Ordovician Kirk River Beds are exposed, and basal units of the overlying Burdekin Basin sediments are also preserved in some areas.


Figure 4: Regional surface geology map (1:100,000), coloured for major geological provinces and sub-provinces. EPM14778 tenement outline is marked in black (shaded portions represent relinquished sub-blocks), with major roads (red), and drainage (blue) marked.

Within EPM14778 Ordovician granites and granodiorites are dominant, with lesser Silurian to Devonian granodiorites, tonalites and diorites. The Tuckers Igneous Complex (in the group of seven south western sub-blocks) is the only major occurrence of Carboniferous to Permian rocks in the EPM. The Charters Towers Metamorphics are exposed along the east-west Alex Hill Shear Zone (see below), and the Kirk River Beds outcrop in a small area on the eastern edge of the tenement. Sitting unconformably on both Charters Towers Metamorphics and Ordovician granitoids in the eastern-most part of the EPM are conglomerates and sandstones of the Collopy formation, which represent the last remnants of the Devonian Burdekin Basin cover sequence within the EPM. Several small Tertiary olivine basalt pipes outcrop around the township of Mingela and probably correlate with the large basalt flows found north-west of Charters Towers. Tertiary to Quaternary unconsolidated alluvial-colluvial cover sediments can also be found in the northern parts of the EPM.

The Alex Hill Shear Zone (AHSZ) is the major structural element within the EPM and is interpreted to be a crustal-scale, sinistral, transcurrent fault, with a possible early reverse fault (south block up) history (Standing, 2006). The shear zone is characterised by an approximately 1km wide zone of strongly to intensely foliated Charters Towers Metamorphics and mylonitic Ordovician granite. The foliation within the surrounding granite is more widely distributed on the southern side of the shear zone, with localised mylonite zones observable up to 1km away from the interpreted core of the structure. The ~60koz Christian Kruck gold deposit to the immediate west of the EPM sits on the sediment- granodiorite margin on the edge of the shear zone, and is intricately linked to movement


along this structure. The AHSZ and other related east-west orientated structures appear to be cross-cut / truncated by later NNW-trending structures. These may be related to the Burdekin Lineament further west, where a strong locally mylonitic NW striking fabric has been observed within the Charters Towers Metamorphics (Hutton et al., 1994). Within the project area, these major structures have only been identified in aeromagnetic images, and not in the field.

5. PREVIOUS COMPANY EXPLORATION

Previous company exploration activity in the region has predominantly focussed on locating gold mineralisation associated with mesothermal veins as well as magmatic breccia pipes.

Previous company exploration has included:

A to P 360 Anaconda Australia Inc 1966-1968Area 1 of the three separate areas comprising the authority to prospect overlapped EPM14778. Anaconda targeted copper mineralisation associated with the adamellite differentiate of granite phases and gold-copper mineralisation during a search of the region for porphyry copper style mineralisation. Work carried out within Area 1 of the tenement included stream sediment sampling, costeaning and inspection of workings on auriferous quartz veins at Mountain Maid, Commotion and Oaky Creek. Eleven areas of copper mineralisation were located within Area 1.

It was concluded that the copper anomalies were associated with only narrow zones of disseminated sulphides and copper carbonates within granites, and were of low order. As such, the potential for economic mineralisation was discounted. Similarly, the areas of gold mineralisation were considered to have little economic potential and the area was recommended for relinquishment.

A to P 648M Planet Metals 1969-1973Planet Metals completed stream sediment sampling, soil sampling and diamond drilling at the Titov and Keans prospects. Exploration activities targeted porphyry copper and molybdenum deposits. No significant results were obtained.

A to P 2642M Camira Mines NL 1981-1983Camira completed a regional panned concentrate sampling program and reviewed known areas of mineralisation. Work concentrated on the Himalaya and Margaret prospects outside the current tenement in the Silver Valley area. Results from within the current tenement were discouraging.

A to P 4210 Gold Mines of Kalgoorlie 1986-1993Exploration was carried out on A to P’s 5150, 5738, 5739, 5740 and 5075 in conjunction with A to P 4210. The aim of the work was to locate economic open pittable gold resources.

The exploration programs completed included geological mapping, stream sediment sampling, rock and soil auger sampling, ground magnetic surveys, airborne magnetic / radiometric surveys, induced polarisation surveys, rotary air blast, reverse circulation and diamond drilling.

In addition to the resource outlined at Althea – Christian Kruck, located near the western boundary of EPM14778, five other prospect areas were drill tested. King Solomon, Grass Hut, Rose of Allandale, Kitty Cummings and Milnes Reward – Chas Madge. Continuation


of work on these areas was interrupted due to changes in the company ownership.


A to P 4789 Newmont Australia Limited 1986-1987Newmont undertook a regional stream sediment sampling program and follow up sampling programs in A to P 4789 and adjoining tenements A to P’s 4788 and 4781 testing for gold mineralisation. Initial anomalous values from stream sediment sampling could not be repeated, and it was concluded that the majority of drainage anomalies were due to reworking of Mesozoic sediments. The probability of economic concentrations of gold mineralisation in the area was therefore considered remote, and it was recommended that the area be relinquished.

A to P 5097 Dalrymple Resources NL 1986-1990The area was tested for gold mineralisation by undertaking stream sediment sampling, rock chip sampling and geological prospecting and traversing. Five previously unidentified prospect areas were located Cicada/Hanging Valley, Four Mile, Hill Top, Kings Cross and Horse Camp.

It was concluded that none of the areas warranted drill testing and that the Collopy Formation was the source of anomalous drainage samples at the Cicada/Hanging Valley, Four Mile and Kings Cross prospects. The narrow quartz sulphide veins at Oaky Hill North, Hill Top, West Haughton, Bluff Creek and Horse Camp prospects were considered to have no significant tonnage potential to warrant further work.

A to P 5075M Australian Overseas Mining Limited 1987-1990Exploration consisted of an appraisal of previous exploration in and around the area, aerial photography analysis and a photogeological study. Work completed under a joint venture agreement with Gold Mines of Kalgoorlie (GMK) consisted of a detailed stream sediment sampling program followed by reconnaissance mapping and sampling. Results were generally negative and no significant zones of mineralisation were identified.

EPM10488 SMC Gold Limited 1995-2004Exploration included regional mapping, rock chip sampling, acquisition of aeromagnetic data and soil sampling programs in the railway cutting and Springview prospect areas. The EPM was originally granted to Aurora Gold Ltd (and others) prior to SMC Gold ownership, with the majority of the work completed prior to 2001. Results were generally poor and no drill targets were defined.


6. WORK COMPLETED BY CARPENTARIA GOLD

6.1 Regional Exploration

6.1.1 Aeromagnetic / Radiometric Survey

Fugro Airborne Surveys Pty. Ltd. (FAS) flew a regional 3-sensor system airborne magnetic and radiometric survey between the 30 th of July 2006 and the 9th of August 2006. Total coverage of the survey was 10,365 line kilometres (953 sq. km), including 179.4 sq. km over the relinquished portion of EPM14778. The survey was flown north-south at 100m line spacing (35 to 50m flight height) using an Aerocommander Shrike 500-S aircraft. The final raw data set was forwarded to the department on the 22nd January 2007. Images of the aeromagnetic and radiometric data have been produced (see Drawings 70137-70139).

6.1.2 Regional Geological Traverses

Structural geology consultant Jon Standing and the Ravenswood exploration team conducted a series of regional geological traverses in order to increase our understanding of the structural framework of EPM14778. Three traverses covered portions of the relinquished sub-blocks:

Traverse 7: Burdekin Lineament / Hadleigh’s Castle Trend: examined NW fault structures such as the Burdekin Lineament, mineralisation in the Hadleigh’s Castle trend and fault structures possibly associated with the AHSZ.

Traverse 8: Alex Hill Shear Zone (AHSZ) hinterland: examined the southern margin of the AHSZ.

Traverse 9: Alex Hill Shear Zone East: examined the AHSZ and the unconformity with the Collopy Formation.


Figure 5: Geological traverses covering relinquished portion of EPM14778, with major roads (red), major drainage (blue) marked for reference.

During the campaign, all publically available Charters Towers region geochronology was complied, and a report titled the “Tectonic Setting and Evolution of the Eastern Half of the Ravenswood Batholith” was produced. The following is a history for the Batholith from Neoproterozoic time through to the Early Carboniferous as described by Standing (2006) who summarized and modified the work of Hutton et al (1994), Switzer (1998), Kreuzer (2004) and Fergusson et al. (2005).

D1: Penetrative foliation developed within the Neoproterozoic Cape Range Metamorphics (including the Charters Towers Metamorphics).

D2: Refolding of S1 during extension associated with the deposition of the Seventy Mile Range Group during the Delamarian Orogeny.

D3: Intrusion of Middle Ordovician – Early Silurian granitoids with development of major E- W shear zones with steep pitching stretching lineation in the foliation (S-blockup / N-block- down) in the northern half of the batholith (Alex Hill, Mosgardies, Hellhole Gorge and Tomato Springs Shear Zones).

D4: Sinistral transcurrent movement along the Alex Hill Shear Zone as well as other E-W shear zones under the influence of NE-SW shortening during the Early Silurian.

D5: Intrusion of Middle Silurian to Middle Devonian plutons (Carse-O-Gowrie, Millchester, Broughton River and Rishton granitoids) into active transcurrent faults such as the NE-SW Plumwood-Connolly Fault. Onset of hydrothermal alteration and gold mineralisation at


Charters Towers and Hadleigh’s Castle during Middle Devonian and under the influence of NE-SW shortening and rapid uplift (Kreuzer, 2004, 2005). Deposition of Collopy Formation during the Late Devonian – Early Carboniferous.

D6: Ongoing NE-SW directed shortening caused rupture of the sinistral Jessop’s Creek Fault and dextral reactivation of the Plumwood-Connolly Fault,

D7: E-W to WSW-ENE directed shortening, reactivation of all faults and rupture of N-S thrusts and hydraulic extension veins during high temperature (300-400°C) lode-gold and magmatic breccia gold events at Ravenswood and Mt Wright during Late Carboniferous – Early Permian.

6.1.3 Stream Sediment Sampling

Fifty two combined –4mm BCL (CG109876, CG109892-898 (even numbers only), CG109904-906 (even numbers only), plus CG110101-145) and –80# (CG109877, CG109893-899 (odd numbers only), CG109905-907 (odd numbers only), plus CG110101-145) stream sediment samples were collected from the relinquished area in the vicinity of the Alex Hill Shear Zone. Note: the majority of –4mm and –80# sub-samples were allocated the same sample number, although some were allocated individual numbers. Samples were generally collected approximately 500 to1000 metres apart as infill to previous wide spaced stream sediment sampling. All 52 samples from the program were submitted to ALS for Au, Ag, Cu, and Pd (BCL) and –80# Ag, As, Cd, Cu, Pb, Sb, W, and Zn (ICPAES) analysis.

With the exception of one sample (8.1ppb), all Au results were < 1ppb (see Drawing 70140). No significant base metal anomalies were identified, although samples collected around Sulphide Mountain returned generally higher Cu values (averaging around 20ppm). Another four samples collected at about 463350mE, 7800565mN (approximately 2km SE of Mingela) also returned slightly elevated Cu values around 35ppm. Limited follow-up work was completed around both areas (see below).

6.1.4 Regional Soil Sampling

A regional –80# soil traverse consisting of 36 samples (CG110318-353) was conducted across the Alex Hill Shear Zone to the south of Mingela. Samples were collected at 100m centres along a line ~3km in length. Only 24 samples were submitted for analysis as the samples collected in the northern part of the traverse were believed to be “contaminated” by Tertiary/Recent colluvium/eluvium (possibly associated with the weathering of the Devonian Collopy Formation). Samples were sent to ALS Townsville for Au assay by method TL43 (aqua regia digestion + ICP spectrometry) plus 50 element ME-MS41 (aqua regia + combined ICPMS/ICPAES) analysis. Results for all samples were ≤1ppb Au (see Drawing 70141), but values of >100ppm for Cu and Pb were obtained from a single sample (CG110332) collected in the vicinity of several small prospecting pits. No further work was completed.

A larger campaign of regional soil sampling was conducted across the tenement. Initially, a program of 500x500m spaced soil sampling was completed over an area immediately west of Mingela. A total of 49 -80# samples (selected samples between CG112205-405) were collected from the relinquished sub-blocks. These samples were submitted to ALS for Au assay by method TL43 plus 50 element ME-MS41 analysis (see Drawing 70141). A mixed 1x1km and 2x2km spaced soil sampling program was subsequently undertaken, with 82 soil samples (selected samples between CG107123-379, CG10711-114, CG113085, CG113474, CG113485) collected from the relinquished portion of the EPM. These samples were submitted to ALS for analysis by ST43 (aqua regia digestion with Zeeman Graphite


furnace spectrometry) and also the suite of 50 elements by MS41 (Note that samples CG107123-339 were also initially analysed by method TL43). To ensure that the Au results from both programs were consistent, 14 of the 54 samples from the initial 500x500m grid (samples between CG112205-405) were re-assayed for Au by method ST-43.

Results (ST43) were generally disappointing, with only 3 samples returning Au values greater than 2ppb, up to a maximum of 4.5ppb (see Drawing 70142). Maximum values for other elements included 0.12ppm Ag, 8.1ppm As, 1.9ppm Bi, 84.8ppm Cu, 2.25ppm Mo, 138ppm Pb, 1.42ppm Sb, 0.15ppm Te, 1.07ppm W, and 121ppm Zn. No areas worthy of follow-up were identified.

6.1.5 Regional Rock Chip Sampling

During regional traverses and soil sampling, 25 rock chip samples (CG118459-460, plus selected samples between CG118723-880, and CG119110) were collected. Twelve of the samples were submitted to ALS Townsville for fire assay by method AA-25, with six also analysed for 48 other elements by method ME-MS61 (four-acid (HF-HNO3-HClO4-HCl) digest with ICPAES/ICPMS analysis). The remaining 13 samples were submitted to the Ravenswood Mine lab for Au analysis (only) by the PAL1000 (Pulverise and Leach) method. Two samples returned Au assays greater than 1 g/t, up to a maximum of 7.24 g/t (see Drawing 70143).

6.2 Mingela Region

6.2.1 Soil Sampling

Eighteen –80# soil samples (CG110479-496) were collected as follow-up to two single- point BCL soil anomalies (209ppb and 132ppb Au) which were collected by MIM in 1992, approximately 2-3km south east of Mingela. As well as re-sampling near the original locations, additional soils were also collected along short, 50m spaced east-west lines. The original 209ppb Au anomaly was found to correspond to subvertical (?) northeast trending quartz (+ minor sulphide) veins hosted by the Mingela Granodiorite, near where slightly anomalous Cu values were obtained in stream sediment samples (see above). The other anomaly (132ppb Au) corresponds to quartz (+ minor pyrite) veining in Charters Towers Metamorphics within the core of the Alex Hill Shear Zone, in an area previously disturbed by earthmoving equipment (possibly for road building material). The samples were submitted to ALS for Au analysis by method TL43 (aqua regia digestion with ICP spectrometry analysis). Best results included 22ppb and 16ppb Au from 50m and 150m east of the original MIM soil line, with most of the other samples either at or below the detection limit (see Drawing 70144). No further work was conducted.

6.2.1 Rock Chip Sampling

Eleven rock chip samples (CG118551-557, CG118560-563) were collected near the MIM soil anomalies to the south east of Mingela. Samples were submitted to ALS Townsville for Au analysis by method AA25 (30g fire assay). Results returned a maximum value of 0.31g/t Au from CG118563, with all other results ≤0.1g/t (see Drawing 70144).


6.3 Sulphide Mountain

6.3.1 Reconnaissance Mapping

The Sulphide Mountain workings (1934-40) are centered on a 1-2m wide quartz-sulphide vein with a strike length of ~300m. Records indicate that 62oz of Au and 707 oz of Ag were extracted from 64 tonnes of ore, with the deepest shaft reaching 10 metres. The dominant rock type in the prospect area is the Ordovician Mingela Granodiorite, which has a moderate to strong sub-vertical foliation, trending roughly east-west. The granodiorite is intruded by more intermediate to mafic, fine-grained units, with up to 2cm hornblende phenocrysts. These units have a weak mineral alignment along their margins, but are generally not foliated. Five major quartz + sulphide veins with strike lengths >100m were identified with the majority of quartz veins dipping between 50-80 degrees to the north- west. Where present, sulphide minerals include pyrite, chalcopyrite, galena and sphalerite, and many of the veins are associated with malachite (and minor azurite), particularly within the wall rock.

6.3.1 Rock Chip Sampling

Thirty nine rock-chip samples (CG118461-463, CG118512-547) were collected from the Sulphide Mtn area, most of which were quartz +/- carbonate veins with varying amounts of sulphide minerals (dominantly pyrite). All samples were submitted to ALS Townsville for Au (fire assay) and Ag, As, Cd, Cu, Pb, Sb, W and Zn analysis by method ICP41 (aqua regia digestion with ICP spectrometry). The best Au value was 174 g/t from mullock near the main workings, with seven other samples returning assays > 1 g/t (see Drawing 70145). Gold grade appears to broadly correspond with elevated levels of Ag, Cu and Pb + Zn, with no correlation to As or W. Two samples (CG118461 and CG118527) contained 1.5 and 1.2% Cu respectively, both of which corresponded to Au assays < 0.4 g/t. In addition, five samples returned Ag assays > 100 g/t, all of which correlated to high Pb (>1000ppm). Despite several high grade results, the lack of grade continuity along strike and the generally poor number of mineralised veins indicates that the possibility for an economic (stand-alone) orebody in the area is low and no further work was warranted.

6.4 Sampling Quality Assurance and Quality Control

QAQC sampling was conducted for all sampling programs. All surface geochemistry QAQC is included with the associated samples in the corresponding geochemistry .txt files submitted with this report.
