Lithium Australia NL (ASX:LIT) has received the interpretations of results from a soil survey conducted on the Mount Day JV tenement with Okapi Resources (ASX:OKR) at Lake Johnston in Western Australia, confirming the gold-in-soil anomaly over around 2 kilometres in strike.
The interpretations also confirm three other less defined anomalies with pathfinder elements such as silver, copper and molybdenum supporting the gold trend of showing a consistent north-south fabric, highlighting underlying structural control.
A difference in gold tenor of the two surveys has shown a likely inconsistency between the two survey sampling techniques.
Mount Day tenement
Tenement E63/1903 is at the southern end of the Lake Johnston Greenstone Belt in central Western Australia.
The belt hosts the Lake Johnston nickel mines owned by Poseidon Nickel (ASX:POS) around 10 kilometres from the Maggie Hays and Emily Ann underground nickel mines and also the Windy Hill accommodation village also owned by POS.
Additionally, Okapi has applied for an adjacent tenement (E63/2039), to cover a target defined by coincident structural and geochemical criteria.
The area has been the focus of nickel and lithium exploration with limited follow up on the gold potential.
This tenement application process has been delayed due to the impact of COVID19 during 2020.
Okapi is hopeful that the tenement will be granted in the current quarter.
Two new adjacent anomalies
The recent soil survey was designed to infill the existing 400 metre spaced survey lines on E63/1903 to better define drilling targets.
It was conducted on 400 metre spaced lines along line spacing of 50 metres, for 519 samples collected.
Whilst the gold values were of a low tenor when compared with the existing historical data they were consistent with, and reinforced the main gold-in-soil anomaly over approximately a 2km strike length.
Furthermore, there are two new adjacent anomalies.
Detailed ground magnetics survey to take place
All the identified anomalies are planned to be covered with detailed soils (100 metres x 25 metres) to better define drill targets.
The pathfinder data shows a consistent north – south fabric suggesting some underlying structural control could be present.
Okapi plans to undertake a detailed ground magnetics survey in the current quarter to better define the underlying structure.
