E79 Gold Mines Begins Core Drilling at Laverton South Gold Project
E79 Gold Mines (ASX: E79) has begun a major new phase of core drilling at its flagship Laverton South gold project in Western Australia.
The 20,000 meter program is designed to fill a 1.6 kilometer long gold anomaly outlined by first core drilling earlier this year on the project’s Target 3 prospect.
The anomaly remains open along the strike.
The drilling is expected to provide detailed geological information ahead of deeper reverse circulation work planned before the end of the year.
Several air core programs are also planned at Yindana Lake to test greenstone targets and intrusions discovered during recent gravity surveys.
Drilling of these targets will commence once heritage survey permissions have been received.
Managing director Ned Summerhayes said the E79 team wanted to continue testing key targets at Laverton South.
“Target 3 will be a priority for tracking air cores to better understand controls on mineralization,” he said.
“We will test the southern extensions of the target and also test several pristine targets at Yindana Lake, pending heritage survey clearances.”
E79 will also explore along strike to the south of structures that trend towards Kirgella’s Gift, located 4 kilometers southeast of Laverton South, where drilling by Renaissance Minerals in 2011 intersected thick, high-grade gold mineralization.
Renaissance was acquired by Emerald Resources (ASX: EMR) in 2016.
No gold anomaly
E79 has confirmed that all assays from aircore drilling earlier this year have been returned, with results from 200 holes over 8122m from the Target 4 green fields showing no significant gold anomalies.
Drilling tested the western and southern edges of a felsic intrusion in greenstone, where historical soil samples had identified a gold anomaly.
“While the results are disappointing for us, these targets represent only a small portion of our building block and exploration will now focus on other project targets,” Mr. Summerhayes said.
Laverton Tectonic Zone
The Laverton South project covers an area of 346 square kilometers over a southern part of the Laverton Tectonic Zone (LTZ) in the main Archean gold-producing Yilgarn craton.
The LTZ is one of the richest gold belts in the world with over 30 million ounces of historical production, ore reserves and mineral resources.
It hosts many mines in production, including Granny Smith (3.7 Moz), Sunrise Dam (10.3 Moz) and Wallaby (11.8 Moz).
