Lefroy looks to extend flight time at Hang Glider Hill

Special Report: Lefroy has kicked off a surface auger drilling program to evaluate a broad, untested area about 2km from its prospective Hang Glider Hill gold discovery.
After kicking off its 2020 activities with a new 4000m reverse circulation drilling program at the Lucky Strike prospect near Kalgoorlie to infill the previous high-grade hits, Lefroy Exploration (ASX:LEX) is now turning its attention to the area near Hang Glider Hill.
Hang Glider Hill was initially recognised by the discovery of gold nuggets that was supported by gold anomalies (low-grade mineralisation) in auger surface sampling carried out in 2018.
This was followed by an early stage drilling program in late 2019 that recorded a shallow intersection of 6.8m at 1.86 grams per tonne (g/t) gold from 53.7m with visible gold.
The company now has a surface auger drill program underway about 2km along strike to the northwest of Hang Glider Hill to evaluate the broad, untested area, and extend the gold in auger anomalies defined in 2018.
Any gold anomalous trends generated from this program will be followed with more focused and deeper aircore drilling.
Hang Glider Hill is about 17km northwest of Lucky Strike, where drilling in 2019 returned a top hit of 9m at 8.67g/t gold from a depth of just 49m within a broader intersection of 19m at 4.52g/t gold from 45m.
Anything above 5g/t is generally considered high grade.
Lefroy recently started a new 4,000m reverse circulation drilling program at Lucky Strike to infill the previous high-grade hits over a 480m strike length of shallow oxide mineralisation to support delivery of a maiden resource estimate.
Other work completed in the December 2019 quarter included an aircore drilling program at the new Mulga 3 target about 3km northeast of Lucky Strike and a reverse circulation drilling program at the Zanex prospect within the Western Lefroy JV with Gold Fields.
The Western Lefroy JV tenements cover 372sqkm adjoining the Gold Fields tenements that make up the St Ives mining operation.
Gold Fields can earn up to a 70 per cent stake in these tenements by spending up to $25m on exploration within six years of the commencement date on 7 June 2018.
Lefroy also won a ballot in 2019 for a new tenement application over the much sought-after Burns copper-gold prospect located approximately 6km south-east of Lucky Strike.
The 21sqkm area seals a former gap in the company’s tenement package and adds a new prospect where drilling by former explorer Octagonal Resources had retuned up to 50m at 0.9g/t gold and 0.5 per cent just 24m from surface.
Drilling by Octagonal also defined a 1sqkm area of gold anomalism and a 2km-long copper anomaly.
