Gateway is poised to start a massive +35,000m drill program aimed at unlocking the potential of its underexplored Gidgee gold project in Western Australia.

Field crews have been mobilised to the project to carry out reverse circulation drilling at the new Lower Zone discovery at the Northwest Margin where previous drilling intersected thick, high-grade gold within a previously unknown intrusive ultramafic unit over a strike length of 220m that remains open to the north and south.

Adding interest, this area has the potential for stacked zones of high-grade mineralisation at depth.

Gateway Mining (ASX:GML) added that final RC assays from its 2020 drilling has confirmed that significant primary bedrock gold mineralisation could be present where aircore drilling has identified extensive anomalism at the Archilles South target area.

Three holes targeting the anomalism extending immediately south of the historical Rosie open pit intersected extensive shearing in the host granodiorite, with associated bedrock gold mineralisation such as 7m at 1.6 grams per tonne (g/t) gold from 50m.

This is consistent with the style of mineralisation that the company had previously intersected north of the Rosie pit and bodes well for future drilling of the multiple extensive anomalies outlined to date at Achilles South over a strike length of 1.4km and is still open for a further 2.5km south to the edge of its tenure.

Managing director Mark Cossom says that further success at the new Northwest Margin discovery could be a real game-changer for Gateway.

“We have also just received the final outstanding assays from the 2020 program, including a significant zone of bedrock mineralisation beneath air-core anomalies at the Achilles South target,” he added.

“This result is significant because it shows that the large areas of well-defined anomalism across the Gidgee Project are likely to host deeper primary mineralisation.”

“This is a very positive sign for the longer-term potential of the project and once again highlights just how under-explored the Gidgee Project is.”

Gidgee drill program

Gateway will initially carry out a 15,000m RC program to test the extents of the Lower Zone along with extending the systematic RC coverage south of the Montague-Boulder open pit toward the Caledonian Northeast pit.

This systematic RC drilling strategy was instrumental in making the key breakthrough at the Northwest Margin discovery.

A diamond rig will mobilise shortly after the RC rig to carry out a planned 3,000m program to test both the deeper potential of the Lower Zone as well as provide critical geological information on this newly recognised ultramafic intrusive.

It will also complete a four-hole program of stratigraphic drilling around the margin of the Montague Granodiorite Dome that is partly funded through a grant from the WA State Government Exploration Incentive Scheme

Following the completion of the RC and diamond programs, an air-core rig will mobilise to site to complete a 20,000m scout program covering near-surface mineralisation and to test additional geochemical anomalies west of the Northwest Margin target area.

The company added that subject to results, both the RC and diamond programs are likely to be significantly expanded.
