Lithium Australia/Okapi Resources gold joint venture at Lake Johnston, Western Australia
Lithium Australia NL (ASX: LIT, ‘the Company) is pleased to provide details of a goldfocused farm-out joint venture (‘the Agreement’) entered into with Okapi Resources Limited (‘Okapi’) (ASX: OKR) for the Company’s Mount Day and Medcalf tenements, located at Lake Johnston in Western Australia (‘WA’).
HIGHLIGHTS
-
Gold-focused Okapi to earn into seven of the Company’s granted exploration tenements (‘the Tenements’), comprising in total an area of 450 square kilometres (‘km[2] ’).
-
The Tenements extend, by 4 kilometres, a gold anomaly identified by Okapi’s geochemist and reported by him as having a total strike length of at least 10 km. Other gold anomalies occur within the Tenements.
-
The Company retains all lithium rights and a significant 25% interest in any gold and nickel discoveries on the Tenements.
-
In addition, the Company is free carried for all gold and nickel expenditure until completion of a definitive feasibility study (‘DFS’).
Terms of the joint venture
-
Okapi will pay the Company a $20,000 deposit to secure the option and has 10 business days from the date of the Agreement to complete legal due diligence.
-
Okapi has 30 days from the date of the Agreement to complete the technical due diligence. Upon satisfaction of the legal and technical due diligence, Okapi may exercise the option to proceed with the farm-in.
-
Okapi will undertake a minimum expenditure of A$150,000 on the Tenements.
-
By undertaking exploration expenditure of not less than $1,200,000 (inclusive of the $150,000 minimum expenditure) on the Tenements within 60 months of the date that the option is exercised Okapi will be entitled to earn a 75% interest in the Tenements.
-
If Okapi acquires the farm-in Interest, it must free carry the Company until completion of a DFS.
The Tenements
Centrally located within the of the 2700-2600 Ma-aged Eastern Goldfields Superterrane (‘EGS’) of the Yilgarn Craton in WA, the Tenements cover geological units typical of the EGS, including Archaean supracrustal sequence (greenstones) dominated by mafic volcanic rocks. Most of the belt has been metamorphosed to greenschist-facies assemblages and is strongly deformed. The greenstones have been intruded by at least three generations of granitic rocks, including pegmatites, among them the spodumene pegmatites at the Company’s Medcalf project.

The ASX announcement lodged by Okapi on 3 September 2020 is included as Appendix I
Comment from Lithium Australia MD Adrian Griffin
"Lithium Australia is striving to add value to its exploration assets and the JV with Okapi is a great step in that direction. The Lake Johnston region has great fundamentals as a gold province but has been overlooked in recent exploration. The area also has huge lithium potential as evidenced by outcropping spodumene deposits on our Medcalf prospect.
==> picture [103 x 126] intentionally omitted <==
The JV with Okapi provides Lithium Australia shareholders with upside for gold and base metal discoveries while retaining 100% of the lithium potential. This is the best of both worlds.”

About Lithium Australia NL
Lithium Australia aims to ensure an ethical and sustainable supply of energy metals to the battery industry (enhancing energy security in the process) by creating a circular battery economy. The recycling of old lithium-ion batteries to new is intrinsic to this plan. While rationalising its portfolio of lithium projects/alliances, the Company continues with R&D on its proprietary extraction processes for the conversion of all lithium silicates (including mine waste), and of unused fines from spodumene processing, to lithium chemicals. From those chemicals, Lithium Australia plans to produce advanced components for the battery industry globally, and for stationary energy storage systems within Australia. By uniting resources and innovation, the Company seeks to vertically integrate lithium extraction, processing and recycling.

Okapi Resources Limited (ASX:“OKR”) (“Okapi” & “Company”) is pleased to advise that the Company has entered into a binding Farm-In Agreement with Lithium Australia NL ( ASX:LIT ) on tenements in the Lake Johnston area, Western Australia. The tenements are located at the southern end of the Lake Johnston Greenstone Belt in central Western Australia. The belt hosts the Mount Holland Gold Mine (Wesfarmers, ASX:WES) and Lake Johnston nickel mines (Poseidon Nickel, ASX:POS) (Figure 1).
In addition, Okapi has applied for an adjacent tenement, to cover a coincident structural and geochemical defined target. The area has been the focus of nickel and lithium exploration with limited follow up on the gold potential.
At the Mount Day Project, Okapi has identified a high priority structural target from the magnetic that is associated with anomalous gold in a coincident soil anomaly over a 10km strike length (Figures 2 and 3). Limited historical drilling near the main target area reported gold - - mineralisation, including LJPC004 (RC): 26 28m 2m @ 11.04 g/t gold and LJPC0058 (RC): 71 74m, 3m @ 1.74 g/t. From the data review undertaken by Okapi, the historical drilling appears to have targeted outcropping material and historical workings, with the main geochemical target not drilled tested.
Okapi will continue a comprehensive review of historical data to complete an infill soil sampling program to accelerate target definition at the Lake Johnston project, targeting both gold and nickel.
Okapi’s Chairman, Rhod Grivas, commented:
“The acquisition of this project marks a significant step for Okapi, fast tracking the Company into an exploration program on an exciting 10km long walk-up gold target in a region that has significant gold and nickel potential with very limited modern gold exploration .”

Farm-in Terms:
Okapi has entered into an agreement with Lithium Australia for the exclusive right to earn an undivided 75% interest in mineral rights, other than lithium, over the Maggie Hays tenements. They key terms are:
-
Okapi will pay a $20,000 deposit to secure the option and has 10 business days from the date of the Agreement to complete legal due diligence.
-
Okapi has 30 days from the date of agreement to complete the technical due diligence. Upon satisfaction of the legal and technical due diligence, Okapi may exercise the option to proceed with the farm-in.
-
Okapi will undertake a minimum expenditure of A$150,000 on the tenements.
-
Okapi will be entitled to earn a 75% interest in the Tenements by undertaking exploration expenditure of not less than $1,200,000 (inclusive of the $150,000 Minimum Expenditure) on the Tenements within 60 months of the date that the option is exercised.
-
If Okapi acquires the Farm-in Interest, Okapi must free carry Lithium Australia until completion of a definitive feasibility study.
Mount Day Project
Project is located ~10km from the Maggie Hays and Emily Ann underground nickel mines and also the Windy Hill accommodation village owned by Poseidon Nickel (ASX:POS). a review of the existing geochemical open file data has identified an auriferous trend over 5.5km long and extends up to 10km. The trend is marked by contiguous anomalous gold in soil samples up to 88ppb and rock chips up to 10.7g/t gold.
==> picture [380 x 314] intentionally omitted <==
Figure 1. Mount Day Project Location
There has been very limited drilling undertaken on the main prospect areas with seven drill holes on Okapi’s exploration licence application, 5 of those reported encouraging pathfinder elements and the best intercept included 2m @ 11.04g/t Au (see Appendix 1).

In addition to the gold opportunity the region hosts nickel deposits in the same geological sequence present in the Mount Day Project.
High Priority Structural Target: The main target at the Mount Day Project straddles the Okapi tenement application and the Farm-in tenement with Lithium Australia. A potential regional strike slip structure has been interpreted from the magnetics (Figure 2). Open file geological mapping has interpreted the greenstone lithologies as being coincident with the geophysical and geochemical anomalies (Figure 4).
==> picture [452 x 374] intentionally omitted <==
Figure 2. Interpreted strike slip structure based on regional aeromagnetic data.
In conjunction with the interpreted regional structure a semi continuous 10km long by 1 km wide anomalous zone has been identified in open file geochemical data (Figure 3). The soil sample results also coincide with a number of anomalous rock chip samples and historical workings. Most of the available rock chip samples appear to have been focussed on old workings and not on the main gold in soils trend, presenting an opportunity for Okapi. Historical drilling in the late 1990’s appears to have been focussed on rock chip results and not the adjacent soil anomaly.
Drilling results from drilling undertaken by LionOre in 2003 include:
LJPC004 (RC): 26-28m, 2m @ 11.04 g/t Au LJPC005 (RC): 26-27m, 1m @ 1.64 g/t Au LJPC0058 (RC): 71-74m, 3m @ 1.74 g/t Au LJPC0094 (RC): 52-59m, 3m @ 0.88 g/t Au, including 1m @ 1.48 g/t Au from 56m LJPD0105 (DD): 43.85-44.15m, 0.3m @ 1.14 g/t Au

Figure 3. Anomalous gold zone from open file data
Tenement Application E63/2039
Okapi has applied for tenement ELA63/2039 (Figure 2.) to cover the regional structure and anomalous gold in soil anomaly. The tenement contains the historical Maggie Hays Hill gold workings; which consist of two lines of SE-trending historical gold workings, hosted in sheared amphibolites and minor felsic units. These are amongst the only historical gold workings in the belt, and have therefore been the focus for gold exploration programmes with drilling located near the outcropping material, The anomalous gold in soil zone sits adjacent to the workings but has not been drill tested.
A priority for Okapi will be infilling the existing soil samples to assist with follow-up drilling.

Section 1 - Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Mount Day Project, RC Drilling and Diamond Core Drilling Results from the DMIRS - WAMEX data system.
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut Faces, 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. |
•All information paraphrased from reports stored on the DMIRS WAMEX open file system. These include the following A numbers: o A053478: Operator Goldfields Exploration Limited. Auger geochemistry. o A71033, operator LionOre Australia (Nickel) Ltd (Reverse circulation drilling (“RC)) and rock chips o A75857, operator LionOre Australia (Nickel) Ltd (RC drilling) o A79561, operator Norilsk Nickel NL (Diamond core (“DDH”) drilling) •Industry-standard RC drilling or diamond core drilling to produce samples of rocks considered prospective for gold or nickel. •Samples of this type, from a respected drilling contractor, is considered fit for purpose. •Industry-standard analytical suites used toprovide analytical results. |
| • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
•No discussion about field quality assurance is reported. Checks of some mineralised samples was completed by a second laboratory. |
|
| •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. |
•Auger Geochemistry (A053478): No information about sampling is included. •RC and DDH drilling to generate samples from holes drilled from surface. •Single metre samples were collected from the RC drill rig, with a subset of three consecutive metres combined to generate 3 metre composite samples for first pass analysis. For more detailed analysis, the original 1m samples were analysed. •RC drilling samples are usually approximately 3.5 kg. •Diamond drilling was completed using HQ or NQ2 sized core. •Sampling of half core with interval determined by lithological boundaries. •With orientated core, the same side of the core is systematically sampled. •Core sample length was up to 2m, generating a sample of at least 3 kg. •Once prepared by the laboratory, the charge assayed is determined by the analytical technique. This can be as little as 3g for 4 acid digestion for base metals, and upto 50gfor a fire assayforgold. |
|
| 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, bywhat method, etc). |
•RC Drilling: 4.5 inch drill string. standard face-sampling hammer. Auxiliary and Booster compressors used to exclude ground water. •Diamond drilling: HQ or NQ2 sized core |

Section 2 - Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | **Commentary ** |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites |
•The geochemistry and drilling reported herein is from tenements that have been surrendered, and subsequently repegged by the current holder or tenement applicant. •One tenement, ELA63/2039, has been pegged by Okapi Minerals Limited in accordance with the WA Mining Act 1978. •Three tenements, E63/1903, E63/1809 and E63/1866, are held by Lithium Australia NL as the registered holder however Okapi has a right to earn a 75% interest in all minerals except LCT pegmatite minerals within the tenements. •The tenements are on vacant crown land. •The listed tenements are within the Ngadju Native Title Determined Area where a determined Native Title Claim exists. |
| • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
•At the time of this Statement the granted tenements are in ‘good standing’, however E63/1866 is the subject of an Exemption (from an expenditure commitment) Application. To the best of the Company’s knowledge, other than industry standard permits to operate there are no impediments to Okapi’s operations within the tenement. |
|
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. | •Previous work of most relevance has been conducted by Goldfields Exploration Pty Ltd, LionOre Australia (Nickel) Limited and Norilsk Nickel NL (which acquired LionOre in approximately 2008. |
| Geology | • Deposit type, geological setting and style of mineralisation. | •The Project is within the Lake Johnston Greenstone belt, comprising rocks typical of Western Australian Archaean terranes, including basal sediments and ultramafic rocks, overlain by generally more mafic rocks. The Greenstones have been intruded by granites. •Gold is grossly classed as ‘orogenic’, forming in late stage quartz veins and adjacent alteration systems. |
| 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, including easting and northing of the drill hole collar, elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar, dip and azimuth of the hole, down hole length and interception depth plus 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 |

| 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 clearlystated. |
•Assays in this Appendix 1, Table 3 are of the interval sampled. •Au in g/t is either converted from ppm (1ppm = 1 g/t Au) or converted from ppb (1 g/t = 1,000ppb Au) •There are no metal equivalent values reported. |
| 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’). |
•Intersections reported in this Appendix 1 Table 2are ‘down-hole’ and do not necessarily represent a true width |
| 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. |
• Refer to figures in this report. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should bepracticed to avoid misleadingreportingof Exploration Results. |
• Reporting of drill details has been provided in Appendix 1 of this announcement. |
| 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 contaminatingsubstances. |
• All meaningful and material exploration data has been reported. |
| 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 commerciallysensitive. |
•Planned further work includes geological modelling – 3DM update. •It’s unclear at this stage whether results warrant a resource estimation. |
