Annual General Meeting 25 November 2016 Creative Resources Leadership Overview § Lepidico is a well funded ASX-listed lithium exploration and development company with an experienced management team § Lepidico’s strategic objective is to become a sustainable lithium producer with a portfolio of assets and pipeline of projects § Lepidico’s exploration initiatives largely focus on hard rock minerals that prior to L-Max® were not traditional sources of lithium § Lepidico is differentiated by having successfully produced lithium carbonate and a suite of by-products from non-traditional hard rock lithium bearing minerals using its patented L-Max® process technology § Lepidico provides exposure to a portfolio of lithium exploration assets through its wholly owned properties, JV’s and IP licence agreements in Asia, Australia, Canada, Europe and South America § At 30 September 2016 Lepidico had A$3.0M in cash and no debt 2 New sources of lithium § Micas and phosphates have been largely overlooked as a source of lithium as no commercially viable process was available to extract the lithium and process through to lithium chemicals prior to L-Max® § Lithium bearing micas Lepidolite and Zinnwaldite contain up to 5% Li2O and like spodumene, are hosted in pegmatites § Lepidolite and Zinnwaldite often occur with tin and tantalum bearing minerals as well as with spodumene § Lithium phosphates such as Amblygonite contain up to 10% Li2O Lepidolite (light purple) Zinnwaldite (dArk grey) Ambygonite/MontebrAsite K(Li,Al,Rb)3(Al,Si)4O10(F,OH)2 KLiFeAl(AlSi3)O10(OH,F)2 -
Session 1 Sources and Availability of Materials for Lithium Batteries
Session 1: Sources and Availability of Materials for Lithium Batteries Session 1 Sources and Availability of Materials for Lithium Batteries Adrian Griffin Managing Director, Lithium Australia NL ABSTRACT Lithium, as a feedstock for the battery industry, originates from two primary sources: hard-rock (generally spodumene and petalite), and brines. Brine processing results in the direct production of lithium chemicals, whereas the output from hard-rock production is tradeable mineral concentrates that require downstream processing prior to delivery, as refined chemicals, into the battery market. The processors of the concentrates, the 'converters', are the major constraint in a supply chain blessed with abundant mineral feed. The battery industry must overcome the constraints imposed by the converters, and this can be achieved through the application of the Sileach™ process, which produces lithium chemicals from concentrates direct, without the need for roasting. The cathode chemistries of the most efficient lithium batteries have a common thread – a high dependence on cobalt. Battery manufacturers consume around 40% of the current production of cobalt, a by-product of the nickel and copper industries. This means cobalt is at a tipping point – production will not keep up with demand. In the short term, the solution lies in developing alternative cathode compositions, while in the longer term recycling may be the answer. Lithium Australia NL is researching the application of its Sileach™ process to waste batteries to achieve a high-grade, low-cost source of battery materials and, in so doing, ease the supply constraints on cathode metals. To ensure that the battery industry is sustainable, better utilisation of mineral resources, more efficient processing technology, an active battery reprocessing capacity and less reliance on cobalt as a cathode material are all necessary. -

A Review of Lithium Occurrences in Africa

Contenders for parental granites are 640-600 Ma Recent research in Norway (Muller et al 2017, or 60-580 Ma “thousands of pegmatites without parental granites”), NW Scotland, Nigeria and Namibia suggests that the low volume partial melting model for the genesis of granitic pegmatites is more prevalent than previously appreciated.

A Review of Rare-Element (Li-Cs-Ta) Pegmatite Exploration Techniques for the Superior Province, Canada, and Large Worldwide Tantalum Deposits

SELWAY, FREDERICK W. BREAKS Precambrian Geoscience Section, Ontario Geological Survey 933 Ramsey Lake Road, Sudbury, ON P3E 6B5 ANDREW G. TINDLE Department of Earch Sciences, Open University Milton Keynes, Buckinghamshire, UK MK7 6AA (Received February 16, 2004; accepted September 20, 2004) Abstract — Rare-element pegmatites may host several economic commodities, such as tantalum (Ta- oxide minerals), tin (cassiterite), lithium (ceramic-grade spodumene and petalite), and cesium (pollucite). Key geological features that are common to pegmatites in the Superior province of Ontario and Manitoba, Canada, and in other large tantalum deposits worldwide, can be used in exploration. An exploration project for rare-element pegmatites should begin with an examination of a regional geology map. Rare-element pegmatites occur along large regional-scale faults in greenschist and amphibolite facies metamorphic terranes. They are typically hosted by mafic metavolcanic or metasedimentary rocks, and are located near peraluminous granite plutons (A/CNK > 1.0). Once a peraluminous granite pluton has been identified, then the next step is to determine if the pluton is barren or fertile. Fertile granites have elevated rare element contents, Mg/Li ratio < 10, and Nb/Ta ratio < 8. They commonly contain blocky K-feldspar and green muscovite. Key fractionation indicators can be plotted on a map of the fertile granite pluton to determine the fractionation direction: presence of tourmaline, beryl, and ferrocolumbite; Mn content in garnet; Rb content in bulk K-feldspar; and Mg/Li and Nb/Ta ratios in bulk granite samples. -

The different industrial uses of lithium are discussed in this review along with a compilation of the locations of the main geological sources of lithium. An emphasis is placed on lithium’s use in lithium ion batteries and their use in the electric vehicle industry. The electric vehicle market is driving new demand for lithium resources. The expected scale-up in this sector will put pressure on current lithium supplies. The European Union has a burgeoning demand for lithium and is the second largest consumer of lithium resources. Currently, only 1–2% of worldwide lithium is produced in the European Union (Portugal). There are several lithium mineralisations scattered across Europe, the majority of which are currently undergoing mining feasibility studies. The increasing cost of lithium is driving a new global mining boom and should see many of Europe’s mineralisation’s becoming economic. The information given in this paper is a source of contextual information that can be used to support the European Union’s drive towards a low carbon economy and to develop the field of research. -

The meeting place is easily recognized through the Abbott farmhouse on the east side of the road, and the ore hopper and pas ture on the west side. The one mile long dirt road up to the mines was passable by car on July l6. If it has been washed out by October we will arrange for jeeps to ferry those few who are unable to walk to the top of the hill.

Carbon dioxide is very abundant in the aqueous liquid and vapor − 12 phases. Occasionally, CH4 was found in the vapor. In the aqueous liquid, HCO3 was detected in 13 fluid inclusions in tantalite-(Mn) from the Morrua Mine and in late-stage quartz from the Muiâne 14 pegmatite and the Naipa Mine, all in the Alto Ligonha District, Mozambique. Moreover, we 15 observed a carbonate (calcite group) in fluid inclusions in garnet from the Naipa Mine and in 16 beryl from the Morrua Mine, both in the Alto Ligonha District, Mozambique, and a calcite-group 17 carbonate and whewellite [CaC2O4∙H2O] in fluid inclusions in topaz from Khoroshiv, Ukraine. 18 The occurrence of oxalate is interpreted to be due to a reaction of some form of carbon (possibly 19 CO or bitumen) with a peralkaline fluid.
