· Preliminary metallurgical test work has indicated that a high-grade (over 6% Li2O), clean, low iron, lithium concentrate can be produced;
· Further exploration underway including mapping and rock chip sampling with drilling expected to commence in around two weeks with the initial focus on defining a JORC resource at Mina do Barroso to support a potential mine development;
· Acquisition is part of an enlarged acquisition that included a 75% interest in four project areas covering up to 1,018km2 of tenure with proven high-grade lithium mineralisation offering additional upside potential;
· Secured Portuguese operating partner Mineralia Minas, Geotecnia e Construcoes, Lda., which has commissioned over 11 quarries and mines in Portugal;
· Portugal has consistently ranked highly in the world for desirability for investment (2016 Fraser Institute study) and is in the top 7 lithium-producing countries (linked to the ceramics industry); and
· Consideration for the Transaction will comprise of initial cash consideration of AUD$1.0million plus the issue of 20,000,000 ordinary shares of 1p each in Savannah ('Ordinary Shares') to the Vendors.
· Additional milestone based, conditional consideration, as summarised below, which could lead to an aggregate consideration of AUD$10.1m (£5.8m) (cash and shares) based on Savannah's closing share price on 24 May 2017.
Savannah's CEO, David Archer said: "This transaction provides Savannah with a unique opportunity to secure what we believe to be one of the most advanced lithium mining concessions in Europe, in a low-cost and stable political environment. With an approved Mining Plan, Environmental Impact Assessment, Mining Licence and the potential to produce high grade lithium product, we believe the Mina do Barroso prospect could transform the European lithium / Electric Vehicle ('EV') industry by becoming the first producer of battery quality lithium in Europe.
"Mainland Europe currently consumes around 25% of the world's lithium and is an early adopter of EVs and battery storage solutions. With battery production by major European manufacturers rapidly expanding, any potential local supplies from mainland Europe are being keenly sought and we believe the Mina do Barroso, together with our enlarged portfolio of lithium assets in Portugal, is ideally situated to address this strategic need. Work is now underway to define a JORC resource at Mina do Barroso so that we may be in a position to make a development decision by the end of 2018. This is undoubtedly a highly strategic and valuable growth opportunity for Savannah."
FURTHER INFORMATION
Savannah is acquiring a 75% interest in actual and contingent assets spread over four project areas with over 1,018km2 of tenure including: one granted mining concession (5.42km2), and nine pending exploration licence applications (the 'Projects').
Of the 1,018km2 Project area relating to the pending applications: 348km2 is on track for government approval and 670km2 is currently subject in part to overlapping exploration licence applications from third parties.
1) TECHNICAL INFORMATION ON THE PROJECTS
The advanced nature of the Mina do Barroso prospect, with an approved ML, MP and EIA means that with the definition of a JORC resource, a development decision could potentially be made by the end of 2018. Mina do Barroso is part of the enlarged Covas do Barroso Project area.

(i) Covas do Barroso Project
The presence of swarms of known 'lithium-bearing pegmatite dykes' has made this region a key focus for Savannah. The initial emphasis is on the Covas do Barroso area, which includes:
1) the advanced 'Mina do Barroso' prospect with approved mining licence;
2) the highly prospective Vilar (223km--2), and Beca prospects; and
3) Reigoso which contains extensive un-explored spodumene bearing pegmatites.
The Barroso-Alvão region is characterised by the presence of a large field of several dozen pegmatite and aplite-pegmatite dykes of granitic composition. Pegmatite dykes are mainly intruded in the granitic rocks of the region whilst aplite-pegmatite dykes are hosted by low- to medium-grade metasedimentary rocks of Silurian age that are strongly deformed (B. CHAROY et al.,1992). The thickness of these dykes ranges from less than 1m up to 70m with the primary focus on lithium rich spodumene-rich aplite-pegmatite dykes.
Mina Do Barroso Prospect
Based on the work Savannah has undertaken to date, the Directors believe that the Mina Do Barroso prospect is arguably one of the most advanced lithium development projects in Europe with the potential to be fast tracked into production.
Past Exploration
Previous work on the prospect has focused on the production of ceramics and not lithium. As a result, the lithium work is largely unstructured but points to significant potential in a relatively underexplored series of pegmatites that have not had their strike, width or down dip potential defined. Work has included reconnaissance geological mapping, trenching, drilling and preliminary metallurgical test work.
Geology and Rock Chip Sampling
The Mina do Barroso Prospect comprises a series of well-defined pegmatites up to 50m in width and 400m in length, with past exploration confirming the presence of lithium within the pegmatites. A series of high priority opportunities have been defined within the prospect area (Savannah Rock Chips Appendix 2A, Vendor Rock Chips Appendix 2B), these include:
NOA
Rock chip sampling by Savannah during April 2017 including continuous rock chips and scattered rock chips average 1.5% Li₂O. The continuous rock chipping outlined significant widths of mineralisation including:
- 30m at 1.18% Li2O in NOA 1
- 30m at 1.35% Li2O in NOA 2
- 35m at 1.67% Li2O in NOA 3
This sampling confirms the prospectivity of the NOA area with a series of pegmatites in the area which require further detailed and systematic exploration.
Reservatorio
Rock chip sampling by Savannah during April 2017 targeting spodumene bearing pegmatites has confirm the prospectivity of the Reservatorio Lens as the samples ranged from 0.87% Li2O to 2.7% Li2O and averaged 1.6% Li2O. Significant potential exists in the Reservatorio area with the potential for the pegmatite to extend over 400m in strike length.
Grandao
The Grandao area contains some of the most extensive pegmatite outcrop in the Mina do Barroso prospect area. Recent rock chip sampling by Savannah in April 2017 in the area returned results of 1.41% Li₂O to 2.07% Li₂O with an average 1.79% Li2O, the highest average grade for any of the Mina do Barroso aplo-pegmatites. However, it should be noted that there is only limited sampling to date and further work is required to determine the potential of the area.

Trenching
A programme of 26 trenches was completed during 2002 ranging from 10m to 125m in length has identified a series of pegmatites ranging from 10-50m in width and up to 400m in length. The trenching was focused on identifying the pegmatites and testing the near surface material for ceramics properties, no lithium sampling was completed.
Figure 8. 2002 trenching being conducted - see PDF link
Drilling
Exploration work by past explorers has included a series of shallow drill holes (115 holes ranging from 7m to 84m in depth, with 75 holes confirmed to contain anomalous lithium) targeting near surface ceramic material (refer to Appendix 1). Lithium analysis has highlighted significant anomalies including:
|
· 10m at 1.1% Li2O from surface in CB2 (EOH) |
· 19m at 1.03% Li2O from 21m in RES01C |
|
· 7m at 1.22% Li2O from surface in CB2 (EOH) |
· 8.5 at 1% Li2O from 2m RES06 (EOH) |
|
· 16m at 1.35% Li2O from surface in GRA05 |
· 14m at 1.04% Li2O from surface in RES07 |
|
· 17m at 1% Li2O from 7m GRA15 |
· 32m at 1.16% Li2O from 20m in RES019 |
|
· 8m at 1.43% Li2O from 32m in GRA028 |
· 11m at 1.1% Li2O from 43m in RES023 |
|
· 22m at 1.1% Li2O from 3m in NOA01 (EOH) |
· 12m at 1.6% Li2O from 1m in RES030 |
|
· 15m at 1% Li2O from 7m in NOA13 |
· 12m at 1.22% Li2O from 16m in SAC01 (EOH) |
|
· 10m at 1.5% Li2O from 2m in RES01 (EOH) |
· 13m at 1.24% Li2O from surface in SP2(EOH) |
Note: Intercepts calculated using a 0.7% Li2O cut-off with no more than 1m of internal dilution and a minimum mineralised width of 7m and an average grade of over 1% Li2O.
Preliminary Metallurgy
Initial preliminary metallurgical test work has been completed by past explorers which indicates that a clean, high quality spodumene product (over 6% Li2O) can be produced from the mineralised rock. The mineralisation at Mina do Barroso compares very favourably to the mineralisation at the Pilgangoora deposits of both Altura and Pilbara Minerals in Australia, and a simple comparison is provided below.
· Altura, Pilgangoora: Resource Grade 1.15% Li2O, 1.7% Fe2O3; concentrate grade >6% Li2O
· Pilbara Minerals, Pilgangoora: Resource Grade 1.29%Li2O, 1.19% Fe2O3; concentrate grade >6% Li2O
· Mina do Barroso: Mineralisation Grade approximately 1.1% Li2O, 0.5%Fe2O3; concentrate grade >6%Li2O
Approved 30 Year Mining Licence, Mine Plan and Environmental Impact Assessment
One of the significant advantages of the Mina do Barroso project is the approved Environmental Impact Assessment and Mine Plan to remove approximately 7Mt of lithium, quartz and feldspar from seven pegmatites within the approved mining licence. The term of the current licence is 30 years: commencing in 2006 and expiring in 2036.
The approvals would need to be modified for the extraction of additional material and to build a plant specific to lithium processing, with this process expected to take in the order of 6-8 months as the changes are an amendment to the existing approvals.
Reigoso Prospect
Field reconnaissance at the Reigoso Prospect highlighted an area of at least, 3 x 1.5km with many outcrops of large pegmatites rich in coarse spodumene. The larger pegmatites seem to be sub-horizontal "sills", indicating that they may have large volumes of pegmatite near surface following the down dip extension of the bodies. The main body seems to be quite extensive with at least one of the bodies with the potential to be at over 50m width and 500m in strike at surface with many other smaller pegmatite bodies. Detailed mapping and sampling of the area is now required to determine the potential of the area.

Figure 10. Reigoso Prospect, massive spodumene crystals up to 1m in size - see PDF link
(iii) Serra d'Arga Project
Savannah has pegged three tenements in the Serra d'Arga area including Calvelo, Ponte de Lima and Caminha. The Serra d'Arga project area covers a swarm of sills associated with the evolution of the diapiric Serra d'Arga granite. The sills exhibit complex associations of lithium minerals.
The spodumene-bearing bodies of aplite and pegmatite can occur intra-granitic, but are mainly found beyond the pluton. In the coastal area north of Viana do Castelo, the bodies of aplite-pegmatite are enclosed in well-exposed metasedimentary host rocks where spodumene may account for up to 20% of the volume of the bodies, and crystals may attain 30cm in length (Gomes & Nunes 1990, Gomes 1992).
The modal proportion of petalite attains 15% in some bodies in the Formigoso area. Some bodies of homogeneous aplite and pegmatite approach 8,000ppm lithium, contain disseminated spodumene-petalite, and lepidolite-bearing pegmatites in the same field may exceed 12,000ppm lithium.
From this exploration, a large pegmatite (>80m) can be seen and the surface indications for W and E indicate that it has, at least, >400m length (see Figures 11 and 12). These bodies seem to be sub-horizontal, so they may have more volume of pegmatite near the surface, following the dip. The presence of feldspar is actually very rare and the percentage of spodumene in this body seems to be around 30 - 40%.

(iv) Barca d'Alva Project
The Almendra-Souto (AS) region is a high priority for lithium resources. Surrounded by highly evolved granitoids, it is a region with metalogenic potential, known by its Sn, W and lithium mineralisation. The region is well known for the presence of pegmatite-aplite veins with the lithium minerals lepidolite, spodumene and petalite (Gaspar 1997; Charoy & Noronha 1999). Savannah has pegged two tenements in the region, Meda and Almendra, covering a number of known swarms.
The Meda project surrounds a small mining lease that covers one of the larger veins of this pegmatite-aplite field (an open pit for the ceramic industry known as Bajoca mine). This vein has an extension of 700m, with variable thickness between a few metres to more than 30m. There are many other lithium occurrences in the area but to date they have been largely explored for ceramic mate rial with little exploration directed toward the supply of lithium carbonate for the battery industry.
(v) Tâmega Project
The area contains numerous pegmatite-aplite veins and rare-element-rich granites. Lithium minerals are dominated by layered petalite, spodumene and montebraisite, hosted in NW-trending aplite-pegmatites that surround a leucogranite. Reserves of lithium as spodumene were mined from the Vieiros tin mines 10km to the NW. Slipstream has pegged the Caramos tenement.
Portuguese Operating Partner
Savannah has formed a strong working and business relationship in Portugal with Mineralia Minas, Geotecnia e Construcoes, Lda. ('Mineralia'). Mineralia is a geological and engineering firm that has commissioned over 11 quarries and mines in Portugal and has been involved in the local mining industry for over 50 years.
Current Valuation
The Projects are not currently capitalised in the financial accounts of the Vendors but costs incurred in relation to previous exploration programmes have been expensed both by the Vendors and by the previous owners of the Projects.
The Company commissioned an independent valuation report utilising the Kilburn Geosciences Rating Method indicating that the value of the Covas do Barroso tenements is between USD851,000 - USD2,240,000 in their current state. In addition, the Company understands that historical expenditure by the prior owner of the Projects prior to Slipstream's ownership (mapping, assaying, drill testing, metallurgical testwork, market studies, and activities associated in applying for and being granted mining licenses and associated environmental and technical studies) was significantly in excess of Slipstream's costs.
2) KEY COMMERCIAL TERMS OF THE TRANSACTION
Savannah has acquired the Portuguese assets through the purchase of an effective 75% shareholding in Slipstream Resources Unipessoal Lda (the registered holder of the Mina do Barroso Mining Licence and the registered applicant for the above mentioned nine pending exploration licence applications).
Savannah acquired its equity interest in Slipstream Resources Unipessoal Lda through a transaction with a consortium of vendors led by Slipstream Resources Investments Pty Ltd ('Vendors').
Savannah and the Vendors will form a joint-venture in relation to both the Mina do Barroso Mining Licence and the remaining exploration licence applications, with Savannah taking 75% controlling equity interest in Slipstream Resources Unipessoal Lda. Savannah shall fund the operations of the joint venture up until a decision to mine is made, after which funding of the joint venture shall be shared pro-rata to respective equity interests.
Consideration
The initial consideration for the Transaction is a mixture of cash and the issue of Ordinary Shares to the Vendors, being AUD $1.0m purchase price and the issue of 20,000,000 Ordinary Shares at the current market price at the time of issue. These 20,000,000 Ordinary Shares (to be held in escrow for six months from the date of issue) will be issued to the Vendors shortly and a further announcement will be made at that time.
Deferred consideration of AUD$1.5m cash and a further 20,000,000 Ordinary Shares of the Company (to be subject to orderly market provisions for six months) has also been agreed to be paid to the Vendors upon the announcement by Savannah of a JORC-compliant Indicated Mineral Resource of 7.5 million tonnes at no less than 1% Li2O ('Milestone 1').
In addition, upon the announcement by Savannah of a further JORC-compliant Indicated Mineral Resource of a minimum of 7.5m tonnes at no less than 1% lithium; final consideration of AUD$1.5m cash and an additional 20,000,000 Ordinary Shares (to be subject to orderly market provisions for six months) be paid to the Vendors ('Milestone 2') (together with Milestone 1, 'the Milestones').
Assuming the Milestones are achieved, the total consideration for the Transaction could equate to an aggregate value of AUD$10.1m (£5.8m) based on the deferred consideration being calculated using the Company's closing share price on 24 May 2017. The consideration is heavily geared towards the Vendors' receipt of Ordinary Shares in Savannah, which will align the respective parties Joint Venture interests and therefore further improve business cooperation in respect of the Projects.
A majority of the consideration paid pursuant to the terms of the Transaction is subject to the successful development of the Project(s) as a result of the Milestones (outlined above), thus minimising initial cost of the Transaction and linking future consideration to a successful Joint Venture and the increase in value in the Project(s).
Mr Dale Ferguson
Mr Dale Ferguson, the Company's Technical Director, is also a Director of and minority shareholder in Slipstream Resources Investments Pty Ltd (one of the Vendors).
As such, Dale Ferguson has been excluded from any of Savannah's commercial negotiations with the Vendors and is precluded from voting on any matters relating to the sale and purchase agreement between Savannah and the Vendors.
Furthermore, as part of the technical due diligence process, Savannah engaged Wardell Armstrong International to prepare a technical report on the Projects.
3) DEMAND FOR LITHIUM
The Directors believe there is a revolution underway in how we generate and use energy. As such, the demand for materials such as lithium, which is a key component in new energy storage solutions, is rising at record rates.
Respected US group, Morningstar Institutional Equity Research, made the following comments in November 2016: "Accelerating electric vehicle adoption will drive global lithium demand far beyond consensus expectations, affording attractive investment opportunities for long-term investors. We expect EV penetration to surge from less than 1% of global auto sales in 2015 to 10% in 2025, well ahead of the market view for only 4%-6% penetration by 2025. We forecast 16% annual lithium demand growth over the next decade, faster than we've witnessed for almost any major commodity over the past century."
Figure 14. Projected increasing lithium demand, Morningstar Institutional research Nov 2016 - see PDF link
Highlight Issued of the European Lithium Market:
· apart from small Iberian production for local ceramics/glass use, the EU has no internal lithium supply;
· the EU is a major importer of lithium consuming 24% of global market (second only to China); and
· lithium processing sites from imported material in several EU countries.
Most of the large car manufacturers are launching models that integrate lithium ion battery technology whilst Tesla, Inc. is aiming to bring electric vehicles to the mass market by lowering costs and entering into battery manufacture with their 'Gigfactory' in Nevada which will initially produce 500,000 units per annum.
It will invariably take time for leading car manufacturers and society to adopt electric vehicles to a point which will impact the lithium market. However, there is growing concern by governments to take action to reduce global warming and pollution of cities by use of fossil fuels and the adoption of electric vehicles can play a significant role. The market for lithium ion batteries has grown markedly following the adoption by consumer technologies - and car batteries require substantially more lithium to power electric vehicles.
Increased use of lithium ion batteries for heavy duty power storage particularly linked to sources of renewable energy off-grid was also projected by Roskill. The increasing use of lithium-aluminium alloys in aircraft manufacture to lighten weight and improve fuel efficiency has good growth potential.
In global terms, China is the largest consumer of lithium - providing approximately 35% of the market's consumption, with Europe as the second largest consumer (24% consumption), and thereby followed by Japan and South Korea.

Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented, multi-commodity, mineral development company.
Mozambique
Savannah operates the Mutamba heavy mineral sands project in Mozambique in collaboration with Rio Tinto, and can earn a 51% interest in the related Consortium, which has an established initial Indicated and Inferred Mineral Resource Estimate of 3.5 billion tonnes at 3.8% THM over the Jangamo and Dongane deposits. Under the terms of the Consortium Agreement with Rio Tinto, upon delivery by Savannah of the following Savannah will earn the corresponding interest in the Mutamba Project: scoping study - 20%; pre-feasibility study - 35%; feasibility study - 51%. Additionally, the Consortium Agreement includes an offtake agreement on commercial terms for the sale of 100% of production to Rio Tinto (or an affiliate).
Oman
Savannah has interests in two copper blocks in the highly prospective Semail Ophiolite Belt in Oman. The projects, which have an Indicated and Inferred Mineral Resource of 1.7Mt @ 2.2% copper and high-grade intercepts of up to 56.35m at 6.21% Cu, with gold credits, provide Savannah with an excellent opportunity to potentially evolve into a mid-tier copper and gold producer in a relatively short time frame. Together with its Omani partners, Savannah aims to outline further mineral resources to provide the critical mass for a central operating plant to develop the deposits and in December 2015 outlined exploration targets of between 10,700,000 and 29,250,000 tonnes grading between 1.4% and 2.4% copper.
Portugal
Savannah holds a 75% interest one mining licence and nine prospective applications for the exploration and development of lithium, covering an area in excess of 1,018km2 in northern Portugal. This includes the highly strategic Mina do Barroso prospect, which with an approved Mining Plan ('MP'), Environmental Impact Assessment ('EIA') and a 30-year mining concession/Mining Licence ('ML'), means that with a defined JORC resource a development decision could be made as early as Q4 2018.
Finland
Savannah has Reservation Permits over two new lithium projects, Somero and Erajarvi, covering an area of 159km² in Finland. Savannah holds a 100% interest in these projects through its Finnish subsidiary Finkallio Oy. Geological mapping by the Finnish Government within the project areas has highlighted the presence of lithium minerals spodumene, lepidolite and petalite with the Government also identifying Somero and Erajarvi as one of the most prospective areas to discover lithium deposits in Finland. Savannah plans to initiate an exploration programme including data compilation, geological mapping and surface sampling with the aim of generating drill ready targets during 2016.

(Criteria in this section apply to all succeeding sections.)

Criteria |
JORC Code explanation |
Commentary |
|
Sampling techniques |
· Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
· Information presented and referred to in this release relate to a combination of historical rock chip samples, bulk samples, channel sampling, RC drilling and diamond drilling sources from a combination of open sourced academic literature and private company information and recent rock chip sampling completed by both the vendor of the project and Savannah. · Key open file reports referenced include Barroso-Alvao Aplite-Pegmatite Field. Granitic Pegmatites: the state of the art - International Symposium. Field Trip Book; Lima, A and Noronha, F, 1999. Spodumene-Petalite-Eucryptite: Mutual relationships and pattern of alteration in Li-rich aplite-pegmatite dykes from northern Portugal The Canadian Mineralogist Vol. 39, pp. 729-746 (2001) Charoy, Noronha and Lima, 2010 The Crystal Chemistry of Spodumene in Some Granitic Aplite-Pegmatite Bodies of Northern Portugal. The Canadian Mineralogist. Vol. 32, pp 223-226. and Moura, S, Leal Gomes, C, and Lopes Nunes, J, 2010. Spatial analysis applied to the Barroso-Alvão rare-elements pegmatite field (Northern Portugal); David Barbose Da Silva, 2014 · Reverse circulation (HQ size) and diamond drill (NQ size) samples were taken on either 1 intervals. Most holes were RC holes were drilled vertically and diamond holes angled at 60degree dip at various azimuths. RC samples were collected in large plastic bags from a cyclone then rifle split and a 2-3kg representative sample taken for analysis. Diamond samples were cut and sampled |
|
|
· Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
· Drilling was conducted on a irregular spacing based on geological targets using RC and drilling technology, an industry standard drilling technique. Drilling rods are 3m or 6m long and 1 sample is taken for each rod interval. · Collar surveys are carried using hand held GPS with an accuracy to within 5m, and the z direction was determined by satellite derived elevation data and is accurate to less than a metre. |
|
|
· Aspects of the determination of mineralisation that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
· Lithium mineralisation is confined to the pegmatite bodies and is predominantly spodumene with petalite. · Down hole sampling is carried out at 1 or 2m intervals from which 3kg of pulverized material (RC) or 3kg of cut material (diamond) was pulverized to produce a 50g charge for assaying
|
|
Drilling techniques |
· Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
· Diamond drilling with hole diameter approximately 81mm, and a drill rod diameter of approximately 75mm, all holes 60degrees inclined to geology which produced a full rock core for sampling. RC drilling at a diameter of 120mm is a form of reverse circulation drilling requiring annular drill rods. Compressed air is pumped down the outer tube and the sample is collected from the open face drilling bit and blown up the inner tube. |
|
Drill sample recovery |
· Method of recording and assessing core and chip sample recoveries and results assessed.
|
· Field assessment of sample volume. A theoretical dried sample mass was estimated to be within the range of 18 kg to 24 Kg, 70% of samples are within the expected range. Lower than average sample recovery is recorded only for the very top of the drill hole due to air and sample losses into the surrounding soil |
|
|
· Measures taken to maximise sample recovery and ensure representative nature of the samples. |
· In the case of diamond drilling, speeds and ground conditions were monitored to ensure good recoveries. · In the case of RC drilling sample weights were monitored to ensure samples were maximized. Samples were carefully loaded into a splitter and split in the same manner ensuring that the sample split to be sent to the assay laboratories were in the range of 2-3kg. |
|
|
· Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
· No obvious releationships
|
|
Logging |
· Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. · Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. · The total length and percentage of the relevant intersections logged. |
· Historical RC drill logs show that all drill holes were logged in the field at the time of sampling. Each 1m sample interval was carefully homogenized and assessed for lithology, colour, grainsize, structure and mineralization. · The diamond drill core was logged onto paper to geological intervals and structural measurements taken where appropriate · Recent rock chip samples were geologically logged
|
|
Sub-sampling techniques and sample preparation |
· If core, whether cut or sawn and whether quarter, half or all core taken. · If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
· Records show that the diamond drilling was cut in half and half the core taken for assaying. · Pictures and indicate that the RC samples were rifle split and sampled dry |
|
|
· For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
· A review of the historical sample preparation method indicates that it was appropriate. · For recent rockchip sampling at least 2kg of representative rock material from a 2m radius around the sample point was collected |
|

|
Geology |
· Deposit type, geological setting and style of mineralisation. |
· The lithium mineralization is predominantly in the form of Spodumene-bearing pegmatites which are hosted in meta-pelitic and mica schists, and occasionally carbonate schists of upper Ordovician to lower Devonian age. The pegmatites are unzoned and vary in thickness from 10m-50m. Lithium is present in most aplite compositions. |
|
Drill hole Information |
· A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. · If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
· See table in main release |
|
Data aggregation methods |
· In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. · Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. · The assumptions used for any reporting of metal equivalent values should be clearly stated. |
· Significant intercepts were calculated using a 0.7%Li2O cut off, no more than 1m of internal dilution and only results over 4m at 1% Li2O have been reported in the summary table of results.
|
|
Relationship between mineralisation widths and intercept lengths |
· These relationships are particularly important in the reporting of Exploration Results. · If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. · If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known'). |
· Exploration results are reported as length weighted averages. · No high grade cuts have been applied to the reporting of the exploration results. · No metal equivalent values have been used. · The drill holes are vertical and the mineralisation is sub vertical. |
|
Diagrams |
· Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
· Relevant diagrams and maps have been included in the main body of the release. |
|
Balanced reporting |
· Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
· All results have been reported. |
|
Other substantive exploration data |
· Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
· The interpretation of the results is consistent with the observations and information obtained from historical data collected. |
|
Further work |
· The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). · Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
· Rock chip sampling, channel sampling and RC drilling. Once planning has been completed the detail will be provided |
