Gateway Mining identifies four new mineralised corridors at Gidgee gold project

Drilling by Gateway Mining (ASX: GML) at its flagship Gidgee gold project in Western Australia has identified four new regional gold corridors outside of the main Montague Granodiorite trend.

A regional assessment and geological review identified the highly-prospective corridors over a cumulative strike length of approximately 20km.

They are believed to open up a major new exploration opportunity for Gateway within Gidgee outside of the currently defined resources.

The company said a series of key geophysical features had been observed in regional magnetic and gravity data within these corridors and required additional drilling or a first-pass test.

Flametree and Ashes prospects

Gateway’s latest drilling was designed to test a number of prospective targets away from the primary Montague intrusion and associated mineralisation.

A program of 54 holes for 3,748m was completed at the Flametree prospect to systematically extend a zone of near-surface oxide gold mineralisation intersected in previous campaigns.

The mineralisation was interpreted to represent a gold “cap” spatially associated with an extensive volcanic hosted massive sulphide copper-zinc-gold mineralised system.

Drilling intersected two flat-lying zones of mineralisation believed to be supergene in nature, with high-grade results of 5m at 10.4g/t gold from 52m, 4m at 3.8g/t gold from 20m, 9m at 1.1g/t gold from 17m, and 5m at 3.8g/t gold from 23m.

The results form part of a clear gold trend which includes the historic Embers and Julia’s prospects, extending over a strike length of more than 5.5km.

Drilling at the Ashes prospect tested a coincident gravity-magnetic target within a 2.5km structural corridor.

It intersected shallow mineralisation associated with ferruginous quartz veining in sandstones in bottom-of-hole samples.

Highly anomalous results returned included 8m at 0.7g/t gold from 24m including 4m at 1.2g/t gold.

New discoveries

Gateway managing director Peter Langworthy said the drilling results confirm the potential for a major shallow oxide gold system within a series of structural corridors “which have not really ever been systematically tested”.

“While our core focus remains on unlocking the potential which exists around the margin of the Montague Granodiorite and along strike from existing resources, we also see potential to make new discoveries outside of the main mineralised contact,” he said.

“The outcomes of our aircore program and recent regional work vindicate this belief and highlight the enormous opportunity to make major new discoveries in completely new areas.”
