Poseidon Nickel Limited updated the market that drilling has now commenced at Lake Johnston's Medusa Lithium Project with Core Drilling Service contracted to complete up to an initial 4,000m of RC drilling. A specialised rubber track mounted RC rig has been engaged to minimise the drill rigs environmental footprint and to navigate the hilly-rocky terrain at Medusa. Medusa Lithium Project The Medusa Lithium Project is located 190km south-west of Kalgoorlie and 6km north of the company's 100% owned Lake Johnston process plant and infrastructure. Previous rock chip sampling of outcropping pegmatites returned results of up to 3.85% Li2O and evidence of Ta2O5. The Company has completed extensive exploration work to date in order to define the drill targets and is now progressing to test these pegmatites for lithium-caesium-tantalum bearing minerals. Poseidon maintains a significant portfolio of tenements in the Lake Johnston region which are highly prospective for lithium hosted pegmatites. The Lake Johnston Medusa Lithium Project lies in a highly prospective area with several ASX listed companies already exploring for and developing lithium mines in the region. The company aims to confirm the prospective nature of the Medusa Project by drill testing for spodumene bearing pegmatites similar to Kidman Resources' Mt Holland spodumene discovery which is located 70km to the west of Lake Johnston. Core Drilling Service has been contracted to complete up to 4,000m of RC drilling at the Medusa Lithium Project. A specialised rubber-tracked Morrooka mounted RC rig has been engaged to minimise the drill rigs environmental footprint and to navigate the hilly-rocky terrain at Medusa. Core Drilling Service are familiar with drilling lithium bearing pegmatites as they are currently drilling at Kidman Resources Mt Holland site and therefore can provide nearby mechanical/operational support as required. During the exploration phase the Company trialled and purchased a Bruker pXRF unit which has been calibrated with the Li_Index algorithm which predicts lithium oxide (Li2O5) grades using elemental ratios associated with LCT bearing pegmatites. This proved successful during the trial phase as well as subsequent testing on samples from numerous lithium bearing deposits. The Bruker pXRF calculates lithium grades within acceptable ranges for mapping and initial sampling prior therefore the Company will utilise the pXRF tool during the drilling campaign to analyse the drill samples prior to submitting them to the laboratory for accurate analysis. This will fast-track geological understanding and infill drill hole planning as laboratory results which can take 4-6 weeks to process. Following the Kidman Option period, Poseidon confirmed that a saleable spodumene concentrate can be produced via the Lake Johnston Operation. Furthermore Poseidon developed know-how and intellectual property on processing lithium through an existing nickel sulphide concentrator, resulting in the application of several co-processing patent applications lodged by the company. Kidman completed detailed engineering in support of a restart at Lake Johnston. All confidential information generated by Kidman and its contractors for the restart of Lake Johnston was transferred to Poseidon.
