The tenement is owned 100% by Auzex Resources Limited (Auzex) and was granted on the 23 January 2008 for a two year tenure. This permit covers part of one of the target areas in Queensland that has all the geological variables required for granite-gold systems, including known mineral occurrences in granite, evidence of granite fractionation, granite composition associated with granite gold systems and a geological association that is most conducive for producing granite-gold mineralisation. Mineral occurrences associated with these intrusions contain a wide range of metals that include Au, Mo, Sn, W, Cu and Bi. Tin has been mined in the Herberton-Mt Garnet district since the 1880s and has in recent years with improvement in price become more prospective. Two days in November 2008 were spent prospecting the tenement for indications of mineralisation, in particular greisen alteration as seen in the nearby Khartoum permit. Prospecting covered E-W traverses (totalling 17 line-km) across the central southern portion of the permit. There were no indications of greisen alteration and mapping revealed only a single 100m long 2 m wide quartz breccia with no visible mineralisation. Compliance with proposed Year 1 program of data compilation, prospectivity analysis and ground-checking has been fulfilled and the area deemed unprospective. Therefore the Petford EPM has been surrendered in full after the first year. 1.1 Introduction The Petford EPM 16021 tenement is located 40 km northwest of Mount Garnet Township in North Queensland. The project area contains a few recorded historical workings most of which have targeted hard-rock fluorspar, molybdenum, tin or tungsten. Alluvial tin were exploited mainly by small syndicates or individuals for more than 100 years from initial discovery in the late 1880s through to the mid-1980s. Declining economics for tin then brought mining to a standstill in 1983. Modern exploration from the 1990s focused on the gold potential of the region and it has been only recently with better tin prices that the focus has returned to tin. 1.2 Tenure Information The Petford EPM application was lodged with the Queensland Department of Mines and Energy on the 1 December 2006 and subsequently granted as Exploration Permit for Minerals Number EPM 16021 on 23 January 2008 for a period of two years. Annual expenditure commitments and sub-blocks reductions were set by the Department at: Years 1-2 - $ 30,000 full retention 11 sub-blocks 1.3 Blocks and Sub-blocks Petford EPM 16021 consists of 11 sub-blocks within the Townsville 1:1,000,000 Block Identification Map as shown in Figure 1.

Mount Garnet is about 105 kilometres south-west of Cairns and 350 kilometres north- west of Townsville (see Figure 2). Access from Mt Garnet is via well maintained gravel roads to Petford and then rough station and former mining access tracks. Alternative access to the tenement is via the formed gravel Herberton-Petford road which passes through Irvinebank and Emuford or the sealed Mareeba- Dimbulah-Chillagoe road which passes Petford. Page 3 Annual Report Petford Project FIGURE 2: PETFORD EPM LOCATION MAP 1.5 Exploration Rationale Carboniferous to Permian (330-300Ma) I-type and A-type volcanic and plutonic rocks are extensively distributed throughout the project area and are part of the Kennedy Igneous Province. These granites are one of the best worldwide examples of highly evolved I-type granites developed on a large scale and contain several prospective supersuites. Current digital data only has been used for this study. No digitizing of historic data or collection of new data has been done. The data discovery and acquisition for this phase of the targeting project has identified significant gaps in digital geological information, especially petrography, geology and geochemistry, in the prospective granite plutons. The data are appropriate for use at a regional scale, but are too broadly spaced for detailed prospect-scale targeting work. This permit covers part of one of the target areas in Queensland that has all the geological variables required for granite-gold systems, including known mineral occurrences in granite, evidence of granite fractionation, granite composition associated with granite gold systems and a geological association that is most conducive for producing granite-gold mineralisation. Mineral occurrences associated with these intrusions contain a wide range of metals that include Au, Mo, Sn, W, Cu and Bi. Tin has been mined in the Herberton-Mt Garnet district since the 1880s and has in recent years with improvement in price become more prospective. 2 REGIONAL SETTING Page 4 Annual Report Petford Project The early-middle Paleozoic Hodgkinson Province succession forms the northern part of the Tasman Fold Belt. The province is the most extensive element in the Cairns Region, where it forms a belt about 500km long and up to ~150km wide. It is separated from the coeval Broken River Province to the south by Carboniferous-Permian igneous rocks of the Kennedy Province and the northwest-trending part of the Palmerville Fault. Lithologies consist dominantly of sandstone, greywacke and siltstone with limestones occurring along the western margin. To the west, the Palmerville Fault defines the boundary with the Proterozoic high-grade metamorphic and associated intrusive rocks of the Dargalong and Yambo Inliers. The Dargalong Inlier is intruded by numerous Early Silurian leucogranitoid bodies grouped together as the Blackman Gap Complex.
