West Australian-based explorer E79 Gold Mines Limited (ASX: E79) has commenced reverse circulation (RC) drilling at its Laverton South Gold Project in WA, where recent aircore drilling intersected multiple zones of gold mineralisation.
E79 Gold has 896 sq. km of prospective ground within its two flagship projects, the Laverton South Project in the world-class Laverton gold district and the Jungar Flats Project in the North Murchison region.
“We look forward to drilling under the gold anomalism and mineralisation we have defined over 2,600m of strike at Target 3,” CEO, Ned Summerhayes, said.
“We will test under the Southern, Central and Western Zones with a series of RC drill holes. This has been a systematic and methodical process to define this prospect with aircore drilling and we are now moving into the potential discovery phase with RC drilling. We are very excited.”
Laverton South Project
Pinjin (100%) and Lake Yindana (100%)
The Laverton South Project, with an area of 355 sq. km, covers a southern portion of the Laverton Tectonic Zone (LTZ) approximately 130km east-northeast of Kalgoorlie, within the major gold producing Archean Yilgarn Craton of Western Australia.
Pinjin – E79 100%
(E28/2283, E28/2284, E28/2375, E31/0999, E31/1005, E31/1007, E31/1056, E31/1082)
E79 Gold recently completed 176 aircore holes for 14,350m in a follow-up programme to in-fill and extend previous gold anomalism at Target 3. This resulted in the definition of a 2,600m long zone of anomalous gold that sits under a regional paleochannel. Within this 2,600m long zone are three distinct gold targets, the Southern Zone, the Central Zone and the Western Zone.
The Southern Zone has >3.0 g/t gold mineralisation in the same stratigraphic position on adjacent drill lines, 300m apart. The northern line of drilling has gold mineralisation to end of hole, the gold is located on an ultramafic/mafic contact and is further confirmed by association with multielement Cu, Pb, W, Sn pathfinders.
This stratigraphic position has been further drill tested by an additional line of aircore drilling, 300m south, with the assays from this line of aircore drill holes pending. The upcoming RC drilling will test for a continuation of mineralisation within the fresh rock underneath these aircore drill results.
The Central Zone is a 600m long and 120m wide zone of thick anomalous gold to end of hole in multiple aircore drill holes, proximal to a greenstone/granite contact. This target sits within a favourable demagnetised zone and alteration in both visual logging and from the short-wavelength spectral analysis showing evidence of large-scale fluid flow with the gold anomalism located in a zone where it is apparent that an oxidised and reduced fluids have mixed.
These features; the gold in a demagnetised zone and at a fluid mixing front (REDOX front), are characteristics seen in a number of large deposits in the region including Granny Smith and Sunrise Dam. The upcoming RC drilling will test under this broad gold anomalism defined to date in aircore drilling.
The Western Zone sits parallel to the Central Zone and is narrower and slightly higher-grade of gold anomalism. This zone sits entirely within the greenstone and to the west of a magnetic high. The upcoming RC programme will also test under this zone.
