On the hunt for Kalgoorlie’s next big gold camp

Special Report: A comprehensive auger drilling program is evaluating 17km of prospective, underexplored ground between Lefroy Exploration’s (ASX:LEX) Hang Glider Hill and the Lucky Strike gold discoveries.
Lefroy is targeting multi-million-ounce gold discoveries on its ground near Kalgoorlie in WA, where it’s methodical approach to ‘generative’ (greenfields, or untouched ground) exploration is already paying off.
At its wholly owned Eastern Lefroy project the explorer has made a couple of exciting early stage discoveries at Lucky Strike and Hang Glider Hill.
In September 2019, Lefroy announced its best ever intersection at Lucky Strike — 18m grading 6.57g/t gold from 68m including a 4m chunk grading an incredible 21.9g/t.
Anything above 5g/t is generally considered high grade.
17km away is Hang Glider Hill, where Lefroy recently uncovered a gold anomaly about 500m wide and 2km long (so far). This includes a high-grade ‘core’ 400m long.
This new shallow augur drilling program is a first pass technique looking for the ‘surface expression’ of more bedrock gold deposits along this 71sqkm, 17km-long trend between Lucky Strike and Hang Glider Hill.
This drilling will cover 25km of the regional scale Mt Monger ‘fault’, which appears to be a major influence on the gold mineralisation discovered at Hang Glider Hill and Lucky Strike.
Faults are geological ‘conduits’ or channels for metal-rich fluids and ultimately, can lead to large mineral deposits.
About 2500 samples will be collected on a regular grid 400m apart with sample points every 40m to cover the entire tenement package.
Any anomalous gold trends generated from this program will then be followed up with more focused and deeper aircore drilling, the company says.
The program is expected to be completed in August with results expected in September.
Lefroy managing director Wade Johnson says auger drilling which covers such a large area along the regional Mt Monger Fault is exciting.
“We have developed a stronger understanding of the geology along the trend from our gold discoveries at Lucky Strike, Hang Glider Hill and Havelock and we now have an opportunity to add more discoveries to the portfolio from a first pass screen of the 71 square kilometre area using the auger drilling technique,” he says.
