    Gateway discovers ‘significant’ new gold zone adjacent to Montague-Boulder Mineral Resource

    Gateway Mining Limited (ASX: GML) reports that it has discovered a ‘significant’ new gold mineralised position immediately adjacent to the cornerstone Montague-Boulder deposit at its Gidgee Gold Project in Western Australia.

    • Thick zones of granodiorite-hosted mineralisation were intersected in RC drilling, confirming a second mineralised structure below and along strike from existing 120koz Mineral Resource. Standout results included
      • Hole GRC583: 5 metres @ 2.7g/t Au from 115m (previously reported)
      • Hole GRC696: 7 metres @ 3.0g/t Au from 84m; 7 metres @ 1.5g/t Au from 113m; and ; 1 metres @ 1.5g/t Au from 102m
    • The drilling was undertaken as part of the 91-hole 14,311m RC program and six-hole 2,550m diamond drilling program targeting the Evermore discovery and other prospective areas within the Northwest Margin target area at Gidgee, which was completed during May 2021.
    • GRC696 was drilled ~75m up-dip of the previously reported intersection in GRC583 and confirmed the presence of continuous flat-lying mineralisation over a dip extent of at least 125m.
    • The newly-identified structure remains untested along strike to the north and south.
    • The results indicate the presence of a series of stacked lodes along the margin of the Montague Granodiorite. The drill spacing remains wide-spaced, providing the opportunity to rapidly expand this position with additional drilling and highlights the potential scale of the mineralised system.
    • These results continue to build on Gateway’s recent success in identifying high-grade gold mineralisation hosted in multiple structures along the 2.5km long Northwest Margin of the Montague Granodiorite Dome.
    • Final assay results from the RC and diamond drilling program are expected in the next two weeks.
    • The company has also commenced air-core drilling to test several large targets across the Gidgee Gold Project.

    Gidgee gold project

    The Gidgee Gold Project is located in the Gidgee district in the Archean Yilgarn Craton of Western Australia approximately 630km NE of Perth and 70km north from the township of Sandstone on the eastern central portion of the Gum Creek Greenstone Belt, of the Southern Cross Province.

    The project area is prospective for both lode style gold deposits and VHMS.

    RC and diamond drilling programs

    The company had commenced extensive RC and diamond drilling programs at Gidgee Gold Project. The drilling completed since July 2020 had successfully identified, and followed-up, high-grade mineralisation over a strike length of at least 420m at the new Evermore discovery; intersected several new high-grade mineralised structures south of the Montague-Boulder open pit; and demonstrated immediate strike extensions to mineralisation in the existing Montague-Boulder Mineral Resource.

    Gateway’s exploration activities have now demonstrated the presence of extensive mineralisation along the entire 2.5km corridor, outside of the previously identified historic open pits.

    Next steps

    • The company is planning further step-out RC and diamond drilling targeting the lower structure down dip and along strike of high-grade gold intercepts. Potential systematic infill of these results may be warranted to begin evaluation of the Mineral Resource potential.
    • Final assay results from the recently completed RC and diamond drilling program are expected to be reported over the next two weeks.
    • The company has also commenced air-core drilling, with planned programs to test several large targets across the Gidgee Gold Project, including further extensions to the Achilles South corridor.

    the latest batch of assays from our recent 14,300m drill program has revealed a significant new mineralised position”

    Management statements

    Gateway’s Managing Director, Mark Cossom, said: “Following hard on the heels of the exciting new Evermore results reported last week, the latest batch of assays from our recent 14,300m drill program has revealed a significant new mineralised position immediately adjacent to the 120koz Montague-Boulder resource.

    These new results extend a historic intercept some 125 metres down-dip, delineating a significant new thick gold zone that sits immediately beneath and adjacent to the existing Resource and historic pit. There is clear potential to expand this zone in both directions and to test the surrounding granodiorite for multiple stacked lodes.

    What is important to note is that our strategy of undertaking relatively wide-spaced drilling across the project has been incredibly successful, demonstrating the scale and potential of the mineralised system and giving us a number of areas that clearly require more tightly-spaced in-fill and follow-up drilling.

    In the meantime, as we await final assays from the recent RC and diamond program we have commenced a major new program of air-core drilling to test a major soil anomaly to the west of Evermore as well as several other targets.”
