Gateway Mining identifies additional high-grade gold trend at Gidgee project

The company’s exploration program has highlighted the trend’s potential to host zones of high-grade mineralisation within a broader mineralised envelope.

Gateway Mining Ltd (ASX:GML) has identified an additional high-grade exploration target at its Gidgee Gold Project in Western Australia.

The mineralised 1.6-kilometre Rosie-Airport gold trend was delineated through a systematic program of data validation, interpretation and targeting of the project’s historical technical datasets.

This work identified the zone as a major structural corridor that includes both discrete contact mineralisation between mafic volcanic rocks and granodiorite and extensive stockwork-mineralised zones within the granodiorite.

New exploration programs beginning in October will focus on resource evaluation and expansion at the Whistler and Montague prospects, as well as geological mapping and drilling at Rosie-Airport.

These activities will position Gateway to estimate a maiden gold resource for the wider Gidgee project.

‘Untapped exploration potential’

Gateway managing director Peter Langworthy said the company’s systematic approach to reviewing the historical data for the Gidgee project was continuing to yield exciting results.

He said: “Each time we interrogate the historical database, we come up with significant new information – and new, high-quality drill targets.

“This shows the substantial and largely untapped exploration potential within our broader ground position at Gidgee.

“Our view is that exploration datasets are a massive asset of resource companies with the potential to host hidden new discoveries.”

Gidgee a potential emerging gold camp

The identification of Rosie-Airport follows Gateway’s discovery of a 10-kilometre-long parallel gold trend along the eastern margin of the Montague prospect and the 4-kilometre-long prospective corridor identified through the company’s maiden drilling program.

This prospective corridor encompasses the advanced Whistler, Montague and Caledonian prospects.

Langworthy continued: “We have been diligently working through 40 years of historical exploration data and … we are unearthing a series of new high-quality exploration opportunities.

“While our immediate focus will be to define a maiden resource position for the project at our high-priority Whistler and Montague targets, we will also continue to pursue the broader exploration potential within our tenements in a measured and systematic way.

“We are increasingly of the view that the large-scale opportunities we have identified form part of what we believe to be an emerging gold camp.”

Rosie-Airport covers a large-scale mineralised shear zone on the contact between mafic volcanic rocks and the Montague granodiorite.

The prospect hosts the historic Rosie open pit mine and has historically assayed: 6 metres at 8.02 g/t gold from 15 metres; 2 metres at 12.8 g/t from 82 metres; and 10 metres at 9.96 g/t from 15 metres.

Historic drilling in the stockwork zone delivered results including 147 metres at 0.42 g/t from 21 metres and 120 metres at 0.42 g/t from 80 metres.

An additional supergene gold target at Rosie South was identified, comprising a high-grade core within a broader envelope of lower-grade mineralisation.

The bedrock controls within the underlying granodiorite are yet to be determined and the strike extensions have not been effectively tested.

Previous drilling results from the supergene zone include: 20 metres at 15.6 g/t from 25 metres; 17 metres at 14.7 g/t from 30 metres; and 15 metres at 5.08 g/t from 35 metres.
