Lefroy Exploration Limited (ASX: LEX) has identified a new 1000m strike length bedrock gold anomaly within BIF trends in the Lucky Strike exploration hub that within the company’s flagship Lefroy Gold Project (LGP) in Western Australia.
The new find was identified through the results of a recently completed 127-hole aircore (AC) drilling programme completed along the Havelock and Lucky Strike Banded Iron Formation (BIF) trends within the Eastern Lefroy (non-JV) project, part of the LGP.
The Lucky Strike Exploration Hub is centred on the Lucky Strike deposit and envelopes the nearby gold prospects identified by the company at Red Dale, Havelock, Neon and the Lucky Strike trend.
Gold mineralisation at Lucky Strike is hosted within multiple north west trending BIF units interbedded with shale. Lucky Strike is hosted within a gold mineralised trend over a 3800m strike length, defined from AC drilling.
The Havelock prospect is located approximately 1.2km south west of Lucky Strike and was generated in 2018 from the company’s assessment of regional aeromagnetic imagery which highlighted a linear magnetic unit which was confirmed by AC drilling as BIF.
A single traverse of AC drill holes completed in July 2020 at 20m spacing intercepted strong quartz veining and highly oxidised BIF similar to the host rocks at Lucky Strike. The best result was 5m @ 1.2g/t Au from 50m.
Managing Director, Wade Johnson, said the new gold system is located 1500m south west of the Lucky Strike gold resource and further enhances the potential for further discoveries along the remaining two km strike of the Havelock trend and along the untested parallel Erinmore BIF trend located 900m to the south.
We are very pleased with the results from the initial phase of aircore drilling along the Havelock BIF trend that has discovered a new gold system,” Mr Johnson said.
“The larger aim of the BIF drill programme was to find and add another discovery in close proximity to the Lucky Strike deposit that had the potential to deliver a resource.
“The 1000m strike length, high grade intersection and sulphide altered BIF are early indicators of such a system and we are keen to get the next phase of drilling underway.”
Significant results from the latest programme include: 1m @ 5.37 g/t Au from 20m; 4m @ 0.78 g/t Au from 27m; 3m @ 1.04 g/t Au from 57m, Including 1m @ 1.82 g/t Au from 59m to EoH; and 2m @ 2.80 g/t Au from 17m.
Planning of the next phase of exploration at Havelock is underway. The programme will include RC drilling to test down dip of the recent intersections and additional AC drilling to scope out the limits of this new trend.
Initial aircore drilling will also evaluate additional targets along the Havelock BIF trend and the nearby Erinmore trend. Drilling is scheduled to commence in March.
