1.0 Introduction and Summary
EPM 14798 is 100% owned by Intermin Resources Ltd. The tenement was granted on 8 August 2005 for a period of 5 years and consists of 100 blocks.
The tenement was applied for due to the presence of marine Cretaceous Toolebuc Formation within the tenement boundary. The Toolebuc Formation is prospective for vanadium and molybdenum, as well as oil shale.
This report summarises the work completed on the surrendered portions during the period of tenure which has included

2.0 Project Location and Access The Julia Creek Vanadium Project defined by EPM 14798 is located approximately 65 kilometres north east of Julia Creek in North West Queensland. The nearest major town, Julia Creek, is a regional service town of 520 people situated 655km by road to the west of Townsville and 255km east of the mining town of Mt Isa.
Access to the southern boundary of the EPM 14798 project area is provided by the east-west Flinders Highway, the main arterial road between Townsville and Mt Isa. Shire roads and pastoral station tracks head north from the highway and provide access to the tenement areas (See Fig 1).

3.0 Topography and Climate
The Project area consists of flat black soil plains typical of the Eromanga Basin in North West Queensland. Very gentle topographic rises are present and often related to outcropping zones of the Toolebuc Formation. Vertical relief in the area is generally less than one metre per kilometre in most areas, except where creeks cross the plains. The major regional surface drainage systems flow to the north west with minor local streams in the project area flowing east west. These rivers and streams flow infrequently, usually during the summer months.
The land in the region is used primarily for grazing cattle which is reliant for stock water on artesian groundwater bores established during the last hundred years.
Vegetation in the Julia Creek region is typically Mitchell grass dominated native pasture with trees and shrubs sparse or absent. Prickly acacia is common in areas of disturbance around existing road quarries and open bore drains.
The climate is described as semi-arid. It is subject to monsoonal influences from the northwest and easterly influences. The annual rainfall gradient declines strongly to the south of the Gulf of Carpentaria.
Around Julia Creek the mean annual rainfall is about 469mm. Evaporation exceeds rainfall by a factor of 5.
The majority of rainfall (about 80%) falls in the summer months between December and March.
Typically the wettest month is January (116.5mm) which accounts for nearly 30% of the rainfall. o o Mean daily maximum temperatures range from 38.7 C in December to 25.9 C in July. Daily o minima vary from 8.3 C in July to 22.8 in January and February.
4.0 Existing Infrastructure
The tenement area is located 65km north east of Julia Creek. Julia Creek, the town administrative centre for the Shire of McKinlay, in the 1998 Census, recorded a population of 1312 people within 2 an area of 40,728km . Of this total population approximately half live at Julia Creek.
The town facilities include a state primary school, a 20 bed hospital, three hotels and a caravan park. Water for the town is sourced from three artesian bores located within two kilometres of the town. The local industry is predominately beef cattle farming with tourism becoming increasingly important. Julia Creek is one of the central transport hubs of north western Queensland, located on the main east west highway and railway with secondary roads radiating outwards to service the region.
Mining is carried out at several locations west of Julia Creek in the Mt Isa Province. The Cannington Silver, Lead and Zinc Mine and Ernest Henry Copper Gold Mine are situated within 150 kilometres of Julia Creek. The Cannington Mine road freights approximately 400,000 tonnes of silver, lead and zinc concentrate to a railway siding 120 kilometres west of Julia Creek prior to being loaded into train wagons and railed to Townsville.
A sealed all weather airport is located three kilometres west of the town and there are scheduled flights from Mt Isa and Townsville three times per week.
The township of Julia Creek receives power via a 66 kV transmission line from Townsville. Advice from the power utility, NORQEB, is that the line is currently at maximum capacity. Construction is proposed for a 66 kV sub-transmission line from Cloncurry to Julia Creek (130 kilometres) and this will connect to the 220 kV Mt Isa power supply. 5.0 Exploration History
Exploration, Previous Work Exploration in the area over the last thirty years has been widespread with a significant proportion of the work focused on the search for oil and process test work of the unoxidised kerogen-rich oil shale.
Period 1968-1973 Mineral tenements were originally pegged by Aquitane in 1968 in the general area of Julia Creek. The initial exploration target was sedimentary uranium in the Cretaceous Toolebuc Formation. Low grade mineralisation in uneconomical quantities was found within a thin unit of the Toolebuc Formation.
The exploration focus shifted to oil and vanadium within the Toolebuc and a new joint venture was formed with The Oil Shale Corporation (TOSCO). Through 1969 the TOSCO – Aquitane J.V drilled 55 holes on roughly a 6km grid east and west from Julia Creek. This work outlined a remarkably consistent mineralised horizon and preliminary mining and processing studies for a proposed oil shale and vanadium project were undertaken.
Between 1970-1973 research was undertaken into vanadium extraction and marketing with a number of potential metallurgical options were explored. Analysis of the unoxidised oil shale identified that 65% of the vanadium is contained in the mixed layer clays, 10% in pyrite and 25% in kerogen. In the weathered oil shale horizon, 25% of the vanadium is typically in goethite and 75% in vanadiferous clays.
Beneficiation tests on oxidised shale suggested that it would be feasible to increase the vanadium concentration, almost twofold, by water scrubbing and separation of the fines from the calcite. The tests indicated that 90% of the vanadium could be concentrated in the minus 30 micron fraction, which represented about 50% of the oxidised shale (coquina?) feed.
Six processes were tested for the extraction of vanadium from oxidised outcropping shale containing no oil and four processes were investigated for extracting vanadium from unoxidised oil shale.
Period 1973-1982 In this period CSR (in conjunction with CSIRO) completed significant work investigating the feasibility of oil extraction from the fresh rock. Extensive drilling was completed throughout the area with a large oil shale deposit of fairly uniform grade located along the west flank of the St Elmo Structure, adjacent to the St Elmo Homestead. (See Figure 2 and Table 1)
A number of different sized projects were reviewed, with a range of processing and refining options considered. In 1979 a significant rise in the oil price prompted renewed enthusiasm for the development of a large scale oil shale project at Julia Creek. In excess of 250 exploration holes were drilled on the western flank of the St Elmo Structure in the vicinity of St Elmo Homestead and reserve estimation completed based on the detailed drilling.
In 1982 the detailed drilling defined an oil shale reserve proposed to be mined by shallow open cut means. The unoxidised oil shale reserve of 1,798 Mt was estimated to contain 63.5 litres of oil and 0.35% V2O5 per tonne of ore. (Whitcher, 1992).
Additional test work and pilot plant studies to investigate oil shale extraction technologies were instigated following advances in retorting technologies. A significant amount of research was completed by CSIRO in association with CSR Ltd.
By 1982 progressive expenditure on the Julia Creek project had reached $15M and it was concluded that the required selling price for oil was A$45/barrel for the project to be economically viable.
Period 1983-1988 Between 1983 and 1988, CSR's activities continued to advance technological research into aspects of oil shale processing before they withdrew from the oil shale project in 1988.
Period 1988-1998 (See Figure 5) Placer acquired the ground in 1988 and completed a review of the data. They withdrew in 1991.
CRA acquired the tenements in 1991 and focused attention on the extraction of oil from the oil shale. They drilled a number of drill holes and completed some metallurgical work at their own laboratory. An extensive review of previous work was completed and data compilation was carried out. CRA withdrew from the project in 1994 after concluding that the production of oil from the Julia Creek deposit was uneconomic at the oil price of the day.

Period 1998-1999 Visiomed (Fimiston) entered into an agreement to acquire a Julia Creek tenement block from Jones and Topsfield in October 1998 following a review of the data and the recognition that a project targeting oxide vanadium mineralisation (without regard to oil in the fresh rock) could be viable.
An active 18 months work followed and involved drilling, sampling, resource estimation, metallurgical sampling, extensive metallurgical test work, process flowsheet design and development.
This work outlined and defined the current vanadium resource and provided a clearer understanding of the stratigraphy, oxidation and vanadium grade distribution in the different geological units.
Inferred and Indicated resources were estimated to total 380 million tonnes at an average grade of 0.39% V2O5 located within 15 metres of the surface. (Figure 2)
A number of samples were collected from drill holes and road quarries in the Project area and submitted to OreTest Pty Ltd for metallurgical testing. A series of tests were completed and a range of potential processing options identified.
From metallurgical test work conducted a method has been devised for the beneficiation of the oxide vanadium material and a method developed for the leaching of the beneficiated concentrate. Test work confirmed that a relatively high-grade concentrate can be readily produced by simple washing and gravity techniques of the oxidised coquina. This concentrate can be leached in alkaline conditions under high temperature and pressure with recoveries of up to 85% returned.
Problems related to high sodium carbonate reagent consumptions and estimated high capital costs, coupled to a significant decline in the price of vanadium, resulted in development and test work relating to the extraction of vanadium from the oxidised coquina being put on hold, awaiting a change in market conditions.
Period 2000-2003 The focus of exploration during this period centred on the oil component of the Toolebuc Formation in addition to metallurgical test work and data compilation reporting the extraction of vanadium from the oxidised and unoxidised portions of the Toolebuc Formation. Rotary Air Drilling was completed to obtain representative samples of fresh oil shale followed by analysis of the samples to determine oil yield and quality.
In addition test work to investigate the extraction of vanadium from ashed fresh oil shale and open file and digital data compilation and review of the oil within the fresh rock of the Toolebuc Formation completed .

6.0 Geology and Mineralisation (See Figs 4,5)
The Julia Creek Oil Shale is located within marine sediments of the Early Cretaceous Toolebuc Formation, a stratigraphic unit that occurs throughout the Eromanga Basin in Central Northern Queensland.
The Toolebuc Formation is a flat lying and distinctive early Cretaceous aged (Albian approximately 120 My) sediment that consists predominantly of black carbonaceous and bituminous shale and minor siltstone with limestone lenses and coquinites (mixed fossiliferous limestone and clays). See Figure 3.
Figure 3
The Formation outcrops only at the margins of the Eromanga and Carpentaria basins or, in the case of Julia Creek, where it is possibly draped over an original basement high. Where the unit outcrops, it forms low rubbly topographic highs which have been the source of road building materials in many areas.
A buried basement ridge, the St Elmo Structure trends in a north north west direction from the Julia Creek Project Area. Outcropping Toolebuc Formation (Klo) is found over a wide area elongated in a north - north west orientation in this area.
The formation is composed of two distinct units, an upper coarse limestone unit termed coquina
Figure 4 Geology
and a lower fine grained carbonate rich unit. It is this bottom unit that contains the majority of the oil. The coquina averages 3-5 metres in thickness and the underlying fine grained oil shale averages 7 metres in thickness. Refer Figure 2. The Toolebuc Formation is overlain by silty clays of the Allaru Mudstone underlain by grey shales of the Ranmoor Member.
Work by Fimiston has established that in the vicinity of St Elmo Station within the fresh Toolebuc Formation, the oil grade of the coquina varies between 7-45 litres/tonne, averaging approximately 24 litres/tonne. In all cases the oil grade of the coquina increased down the section reflects the decrease in the relative amount of calcium carbonate and an increase in the kerogen content.

A resource estimate was based on data from a report by R.Osborne (1982) who detailed by CSR Minerals Division on A to P’s 2610M-2612M. A total of 42 holes were drilled with 1292.30m of open hole drilling and 552.10 m of core drilling. HMLC triple tube core was used to collect the core with 98% recovery. A total of 286 core samples were sent to A.L.S. in Brisbane and analysed for Mo, V and U by XRF and oil by Fischer Retort Method. Field Density measurements were carried out on small pieces of core at 0.5m intervals on fifteen boreholes prior to sampling. An average of 2.1 was calculated as the density.
The data was modelled, wireframed and subject to resource calculations. A preliminary JORC compliant drill indicated and inferred resource is:
1,725 million tonnes @0.31%V2O5 and 271ppm MoO3
The resource attributed to EPM 14798 is:
1,479 million tonnes @ 0.31%V2O5 and 271ppm MoO3
