Gateway Mining Limited (ASX: GML) has announced a series of significant drilling results from the RC drilling at the Montague Gold Deposit within its flagship Gidgee Gold Project in Western Australia.
The company reported that the significant new assays confirm high-grade core, identify extensions and possible new parallel mineralised domain, demonstrating that Montague is part of a much larger gold system.
Significant assays include 10 metres @ 13.0g/t Au from 65 metres; 6 metres @ 2.7g/t Au from 94 metres; 5 metres @ 3.1g/t Au from 114 metres; and 2 metres @ 3.1g/t Au from 123 metres.’
The company said that the exciting new results from Montague continued to build the picture of a large-scale, highly prospective gold system at the Gidgee Project.
The Gidgee Gold Project covers an approximate area of 300 km2 over the southern extension of the Gum Creek Greenstone Belt in WA.
RC drill campaign
The company had undertaken a large 11,000m RC drilling campaign over several targets at Gidgee, which included the recent discovery of an extensive zone of shallow oxide gold at Achilles.
GML reported that it has now completed a total of 10 holes for 1,642m of RC drilling at the Montague Gold Deposit.
The company said that the drilling at the Montague Gold Deposit was designed both to test a number of key areas within the defined resource area and to commence step-out drilling to identify the potential for extensions to the gold system and, in particular, new high-grade domains
Gateway reported that all of the holes intersected mineralisation on the target structure.
Strong RC drill results
The company announced that significant new assay results received from the recently completed RC drilling program at the Montague Gold Deposit.
Highlights include 10 metres @ 13.0g/t Au from 65 metres (hole GRC389); 6 metres @ 2.7g/t Au from 94 metres (hole GRC393); 5 metres @ 3.1g/t Au from 114 metres (hole GRC395); and 2 metres @ 3.1g/t Au from 123 metres (hole GRC391).
Assays confirm high-grade core, identify extensions
The company said that the thick, high-grade intersection returned from GRC389 (10m @ 13.0g/t Au) continues to confirm the quality of the mineralisation within the central high-grade domain.
GML said that the drilling south of the fault has intersected what is interpreted as an extension of the high-grade domain, or possibly a separate new structure (GRC395: 5m @ 3.1g/t). The company reported that the gold mineralisation in this position remains totally open along strike to the south and down-dip.
New parallel mineralised domain
Gatways Minerals said that the deeper drilling down-dip of the central high-grade domain has intersected what is interpreted to be the top of a new, parallel mineralised domain. The company noted that this potential repetition is consistent with observations of the structural controls within the main part of the Montague Gold Deposit.
Outstanding exploration potential
The Montague Gold Deposit is located on the margin of the Montague Granodiorite and is interpreted to be part of the same gold trend that hosts the Achilles Prospect and the NE Caledonian Deposits to the south. This trend, which remains open to the north and south, has been defined now for at least ~2.5km.
The company said that the latest results confirm the potential for the Montague Gold Deposit to form part of a much larger gold system, with outstanding exploration upside both along strike and at depth.
Latest updates and next steps
Gateway said that it continues to receive assay results from the recently completed RC program. The company said that these results will be compiled and interpreted in line with the existing database, and utilised to assess the potential for extensions to existing Mineral Resources at the Whistler and Montague Deposits, as well as areas for further drilling to outline the potential for additional Mineral Resources.
Gateway said that it is embarking on a significant program of integrating all its available datasets – drilling and surface geochemistry, structural interpretation, as well as aeromagnetic, ground gravity and sub-audio magnetic (SAM) geophysics in order to assess the project-wide prospectivity.
The company said that the continued improvements in the geological understanding of the Gidgee Project being achieved by Gateway have highlighted the outstanding potential of the Project to host a significant gold discovery.
Gateway said that the ongoing work will assist in further improving the Company’s geological understanding of existing mineralised areas, as well as to develop new targets for discovering significant gold mineralisation, in order to unlock the Project’s broader potential.
Gateway’s Managing Director Peter Langworthy said: “Following on from the outstanding early success we achieved recently in delineating a significant zone of shallow oxide mineralisation at the Achilles Prospect, the recent drilling in and around the 120,000oz Inferred Resource at Montague has provided further evidence of the substantial long-term growth potential at Gidgee.
The drilling clearly shows that the Montague Gold Deposit has plenty of growth potential and upside and may well form part of a very large gold system that remains to be unlocked.
The quality of the central high-grade domain has also been further enhanced with thick, high-grade intersections such as 10 metres @ 13.0g/t Au.
However, probably the biggest takeaway for us at the moment is that we have a defined a significant gold corridor extending over at least 2.5km that includes Montague, NE Caledonian and Achilles. It’s exciting when you stand back and look at this trend and see that at least half of it has not had an effective drill hole into it!”
