The “Mt Ive Project” forms the western part of the “Gawler Ranges Project”. The “Gawler Range Project” comprises 11 tenements covering a total area of 4,749 km2 in northern Eyre Peninsula. All 11 tenements are licenced to and operated by Menninnie Metals Pty, which is a 100% owned subsidiary of Terramin Australia Ltd. Although all are explored for the same commodities, for administrative and reporting purposes the tenements are grouped into two sub-projects: (1) the “Menninnie Project” comprising 5 tenements (formerly under JV) covering a total area of 2,471 km2 that are grouped under an Amalgamated Expenditure Agreement (AEA), and (2) the “Mt Ive Project” comprising 6 tenements covering a total of 2,278 km2 that have Joint Reporting Status (JRS). The Mt Ive Project lies within the Gawler Craton geological province of South Australia. Almost all of the project area is typified by exposures of Mesoproterozoic Gawler Range Volcanics (GRV) forming rounded hills with intervening valleys containing extensive Quaternary sediments and soils with scattered exposures of low-lying GRV pavements. A small area of medium grained Hiltaba granite crops out within the GRV on EL 5458, and most of the sparse outcrop on EL 5518 Area B is weathered coarse grained Hiltaba granite with scattered occurrences of planar quartz veins. The area is being explored primarily explored for basement hosted, structurally controlled hydrothermal Ag-Zn-Pb and epithermal Au-Ag-(Cu) vein style mineralisation, as well as for possible porphyry-related copper (±Au±Mo) deposits, for skarn/greisen Sn (W,Au,Cu) deposits, and for epithermal systems of Menninnie-Viper Pb-Zn-Ag and Paris Ag types. During the first year of joint annual technical reporting for the Mt Ives Project to 31st December 2016, activists in the project area included the re-establishment and refurbishment of the exploration camp, reconnaissance field work to re-familiarises with the local geology in the northern tenements and regional sampling, the examination of existing JV and open file geophysical data, and the preparation of samples for geochemical and textural investigations. The opportunity was also taken to promote the project to potential farm-in partners which included site visits. A number of access issues that have previously plagued the project and severely restricted exploration in the past were resolved late in the current exploration program. Menninnie Metals maintained regular interactions with the Archimedes Consulting Pty Ltd group and their Archimedes magnetic modelling pilot study of the southern Gawler Ranges area, of which Menninnie Metals is a financial and “ground truth” contributor. The principle aim of the project is to determine the thickness of the Gawler Range Volcanics and to potentially identify internal volcanic stratigraphy. Field visits during the period were focused on known epithermal vein and breccia locations and key regional geological exposures. Additional rock chip and lag samples were collected on reconnaissance field trips from areas where previous geochemical data had been reported. The geochemical results from previous reporting periods, that were not received at the time, were reported during the current period, including portable XRF analysis of soil, rock float and calcrete, and laboratory assay results. Initial testing of the efficacy of microbeam isotopic dating of hydrothermal hematite fragments from hematite-rich breccia, collected on EL 5453 several kilometres south of EL 5266 Area C and east of EL 5430, yielded preliminary data consistent with a 1590 Ma age for deposition of the hematite.
