Discovery Alaska (ASX:DAF) has today disclosed to the market its 100% owned Alaskan Chulitna Project is prospective for lithium with assessment of historical cores from its Coal Creek target showing strong evidence of lithium mineralisation on-site.
Discovery Alaska’s geology team believes its assessment of lithium mineralisation is the first for the mineral conducted in the area with over forty years of drill programs on the acreage missing evidence for the mineral.
The core returning the strong results was retrieved from a state-run archive, the Geological Materials Centre (GMC) in Anchorage, which the company believes hosts over 5000m of relevant cores.
The news saw the company's share price climb over 2% in early morning trades.
Twelve priority drill holes were selected for analysis to determine rudimentary content; Discovery Alaska reports that all twelve drill holes provided positive indications of lithium mineralisation. On these grounds, the company perceives mineralisation is widespread.
Moderate to strong lithium readings continue to the bottom of several of those twelve drill holes, indicating the potential for further lithium bearing geology onsite remaining open at depth within the Cupola Structure.
Discovery Alaska management told the market today the company will accelerate works to test remaining prospective drill cores so as to best provide an initial determination of the scale of lithium bearing zones believed to be present at Coal Creek.
The Coal Creek prospect granite consists of two different geological compositions with outcrops present.
A historical report from Coal Creek centred on prospectivity for tin and silver includes further information on historical drilling and associated assay data which the company may use to fast track the creation of a JORC compliant resource estimate, which would provide financial certainty to the project.
The lithium bearing units on-site are believed to be prospective for other critical battery minerals, including tantalum and niobium.
As of May 19 2022, the price of lithium is up 414% year-on-year.
Statista meanwhile estimate the price of tantalum in 2021 to have been US$158 per kilogram, which comes to $160,500 a tonne; the percentage of tantalum per tonne of ore would of course likely drastically alter the price, making it unclear how much Discovery Alaska could stand to earn.
Contemporary pricing data on niobium prices is difficult to track down, Metalary notes the price for a metric ton of Niobium in 2018 sat at over US$40,000.
