Abstract: The Burnside group of tenements are located approximately 150 km SSE of Darwin along the Stuart Highway. The Burnside mining group covers Bridge Creek, Bridge Creek North, Brocks Creek UG and Rising Tide, Davies Prospect, Fountain Head, Cosmo/Howley Group, Howley Ridge, Iron Blow, Mt Bonnie, Woolwonga and Yam Creek. The tenements were acquired by Crocodile Gold in November 2009 from previous owners GBS Gold Australia. The stratigraphy of the Burnside project area is dominated by the Wildman Siltstone of the Mt Partridge Group and units of the South Alligator Group and the overlying Finniss River Group. This volcano-sedimentary sequence has been moderately to tightly folded along several northwest trending axes within the project area, the most prominent of which are the Howley, Brocks Creek/Zapopan and the Fountain Head Anticlines and the Margaret Syncline. The axial plane of these folds is characterized by intense bedding-parallel faulting and shearing along predominantly northwest trends. The Wildman Siltstone consists of medium to thinly bedded, to laminated fine grained pyritic carbonaceous sediments with minor sandstone and tuff beds, with an overall thickness of approximately 1,000m. The Koolpin Formation consists of sulphidic and carbonaceous argillite, ferruginous chert, ironstone, silicified dolomites and phyllitic mudstones. The contact between the Wildman Siltstone and the overlying Koolpin Formation is partially conformable and partially an angular unconformity. The Koolpin Formation varies in thickness from less than 300 m to in excess of 1,000 m, but its overall thickness is difficult to determine due to the presence of several intrusive sills of Zamu Dolerite, which vary from several meters to a few hundred meters in thickness. The Burrell Creek Formation comprises a 1,500 m thick sequence of turbiditic sediments including greywackes, siltstones and mudstones. The Mount Bonnie Formation is a transitional unit between the Koolpin and Burrell Creek Formations, comprising greywacke, carbonaceous siltstone, chert, tuff and ironstone and with a variable thickness between 150 m and 400 m thick. The Gerowie Tuff (GTF) is up to 400 m thick and consists of tuff, tuffaceous chert and tuffaceous siltstone, with subordinate amounts of laminated cherts and carbonaceous siltstones. Numerous semi-conformable sills of pre-orogenic Zamu Dolerite intrude the Koolpin Formation and the Gerowie Tuff. The post mineralisation Burnside Granite and Mount Goyder Syenite intrude the sedimentary sequence. During the 2014 reporting period Crocodile Gold concentrated exploration activities on the Cosmo deposit and surrounding areas. Some work was completed to sell some titles including the Iron Blow/Mt Bonnie projects. These were part of an agreement with Phoenix Copper who commenced drilling on these titles in late 2014 before the wet season stopped activities. Additional drilling is planned once the rainy season finishes. 260 resource definition diamond holes were drilled at the Cosmo underground deposit, focussing on the F1 Fault on the Eastern Limb of the Howley Anticline with additional holes targeting the Western limb of the Howley Anticline fold hinge. Cube Consulting Pty Ltd updated the Cosmo Mineral Resource and Mineral Reserves estimation; using some of the new resource drilling information. The Burnside and Cosmo Mineral Resources and Reserves NI43-101 technical report was also updated in February 2014. The work completed by Cube Consulting was incorporated in the Technical report as well as an update of the Mineral Reserves for the project. This was completed on the additional drilling and mining information that has been captured on the project over the reporting period. Crocodile Gold also went through a process to relinquish titles that are lower priority for future exploration work. This included the relinquishment of several Brocks Creek MCN titles and the complete Woolwonga project. These were relinquished during the reporting period so these titles have been removed from this group report as the final technical reports have been completed. Crocodile Gold also signed sales agreements with third parties for the Bridge Creek project in December 2014. This project has been assigned at time of completing this report with transfer documents completed and submitted to the department. Reporting for this, as well as the Iron Blow/Mt Bonnie projects, will be incorporated in this technical report as Crocodile Gold is still the registered owner of the titles. This will be transferred to the new owners once the title transfer is complete. Therefore the information provide on work completed on the Iron Blow and Mt Bonnie projects has been supplied by Phoenix Copper. Other activities included a significant campaign to rehabilitate some of the areas at the Yam Creek, North Point, Princess Louise, Temperence and Mt Bonnie mine sites. This involved improving site security and safety with regard to public access to the pits and WRD soil erosion and instability issues.
