Poseidon Nickel Limited (ASX:POS) - A Nickel Mining Story - Update with Karyn Parker.

The segment of Rooster Talk Episode 70 is with Karyn Parker, Senior Exploration Geologist of Poseidon Nickel Limited (ASX: POS).

In the video, Karyn tells us about the prospectivity of the Lake Johnston project. Karyn describes in detail the process in which exploration will be conducted to reveal the prospectivity of the project.

This is an insight into what the team at Poseidon is doing in shaping up the project for a long life mine.

Karyn had considerable responsibility for submitting a highly contested Government Grant application for funding a drilling program at their Lake Johnston site. The Exploration Incentive Scheme (EIS) Grant of up to $180,000 was successfully awarded to Poseidon and will be used for subsidising the cost of the proposed 15,000m drilling program.

The drilling is expected to get underway in early April and will test the highly prospective and underexplored Western Ultramafic Unit for new nickel sulphides. The proposed program aims to delineate and vector towards channel features along the basal contact of the Western Ultramafic Unit, the prime geological setting where nickel sulphides can accumulate.

Karyn is very excited about commencing drilling at Lake Johnston where she will also be looking at opportunities to explore for lithium. Additionally, Karyn will be planning further investigative testing at both the Black Swan and the Windarra sites.

Check out the conversation in this Rooster Talk and, as I always encourage, DYOR.

About Poseidon Nickel Limited (ASX: POS)

Poseidon owns three significant nickel assets with a combined resource of over 400kt of nickel and processing capacity of up to 3.7Mtpa of ore to produce nickel concentrate. The Company’s business strategy is focussed on leveraging its existing asset base to grow Poseidon into a significant nickel producer over a period of expected significant growth in nickel demand largely driven by growth in the electric vehicle market.

Poseidon’s strategic pillars are developing a pathway to production, targeted exploration across its nickel asset portfolio and considering proximal business development opportunities. The key enablers for the Company’s strategy to be successfully executed are ensuring key capabilities are resourced and the business is sufficiently funded for growth underpinned by a strong ESG framework.

Poseidon Business Strategy

The Company’s pathway to production was significantly progressed during FY22 with two metallurgical breakthroughs which could significantly improve the economics of the Black Swan project. The first involves incorporating a rougher concentrate regrind into its process flowsheet to significantly improve the quality of the smelter grade concentrate, which is expected to result in improved nickel payability. The second was testwork on a combined serpentinite and talc carbonate ore blend to produce a rougher concentrate which is amenable to both pressure oxidation and high-pressure acid leach to produce a mixed hydroxide precipitate.

With the assistance of Poseidon’s geological consultants, Newexco, the Company completed an exploration targeting report for Lake Johnston during FY22, with follow up reports for Black Swan and Windarra to be delivered in FY23.

The Lake Johnston report identified the Western Ultramafic Unit as a priority, with a program of works approved to undertake 15,000 metres of RC drilling which is planned for FY23.

The Company’s business development efforts over FY22 focused on delivering value from the Windarra/Lancefield gold tailings project. Partnering with Green Gold and determining whether their proprietary gold recovery technology is suitable for Windarra/Lancefield is considered the optimal path to unlocking value from this project.
