    Follow-up drilling at Gateway’s Gidgee extends gold mineralisation by 70m

    Gateway Mining Limited (ASX: GML) has announced the intersection of significant high-grade gold mineralisation immediately south of the newly discovered Northwest Margin “Lower Zone” at its Gidgee Gold Project in Western Australia. The company said that the new intercept of 7m @ 11.7g/t Au located 70m south of previously reported drilling at the North West Margin confirms an exciting new growth opportunity for Gateway.

    GML said that the key result from the 3-hole follow-up RC drilling program completed prior to de-mobilising the drill rig in November 2020 was GRC630: 7 metres @ 11.7g/t Au from 97m. This result builds on the previously announced intersections to the north.

    Gateway Mining said that the high-grade “Lower Zone” mineralisation has now been defined over a strike length of approximately 220m and remains totally untested along strike to the north and south, representing the Company’s highest priority exploration target at Gidgee.

    The company said that the next phase of evaluation is scheduled to commence in mid-February with a follow-up program of RC drilling. This will be complemented by the arrival of a diamond drill rig in late-February.

    RC drilling at Gidgee

    The company had commenced a13,000m Reverse Circulation (RC) drilling program that targeted the 1.6km mineralised trend between the Montague and Whistler Gold Deposits, on the Northwest Margin of the Montague Granodiorite.

    GML had reported intersections to the north of GRC550: 15 metres @ 3.0g/t Au from 104m and; 10 metres @ 9.2g/t Au from 140m; GRC538: 10 metres @ 2.5g/t Au from 114m.

    Following the announcement of the new high-grade discovery, the drill rig was mobilised back to the Northwest Margin to complete additional three follow-up holes prior to the rig being demobilised from site in November 2020.

    The company has now reported encouraging results from the 3-hole follow-up RC drilling program.

    Mineralisation defined over a strike of 220m

    The company reported that the key result from the 3-hole follow-up RC drilling program completed prior to demobilising the drill rig in November was GRC630: 7 metres @ 11.7g/t Au from 97m.

    GML said that the follow-up RC drilling targeting the previous outstanding discovery results at the Northwest Margin “Lower Zone”, has extended the thick, high-grade gold mineralisation at least 70m to the south, and the mineralisation remains open.

    Gateway Mining reported that the high-grade “Lower Zone” mineralisation has now been defined over a strike length of approximately 220m and remains totally untested along strike both to the north and south.

    Next steps

    The company said that further work would include step-out RC and diamond drilling targeting the new lower structure down dip and along strike of high-grade gold intercepts. Gateway noted that the potential systematic infill of these results may be warranted to begin evaluation of the Mineral Resource potential.

    GML reported that the RC rig is scheduled to mobilise to the Gidgee Project by mid-February. The immediate focus will be on the Lower Zone of the Northwest Margin and the rig will then move in a staged manner to test the highly prospective contact zone south of Montague over an approximate 800m strike length and then onto the Achilles Prospect.

    GML said that the initial follow-up work on the Northwest Margin will then be complemented with a program of diamond drilling to provide detailed information on the stratigraphy and structure in this position. The diamond rig will then move to a series of stratigraphic diamond holes that are partly funded by an Exploration Incentive Scheme grant.

    Subject to the outcomes of this follow-up drilling at the Northwest Margin, Gateway anticipates being able to move into a full-scale resource drill-out in the coming months.

    The company said that it is awaiting results for a further 3 RC holes that were completed as a first-pass test of one of the targets generated from the aircore drilling program.
