Around 18 intrusive gold targets have been spotted across Si6 Metals’ Monument Gold Project (MGP) over a 30km strike as kick off for phase 2 drilling approaches.

A flurry of new results from a geochemical drilling program across the 300km square project in Western Australia’s mining heartland have been classified as ‘fertile intrusives prospective for bulk tonnage gold mineralisation. 18 out of 26 targets drilled were identified as prospective.

Of particular importance is the fact that these intrusives are analogous to those that host the 1.5Moz Jupiter and 0.25Moz Cameron Well deposits within Dacian Gold’s (ASX:DCN) neighbouring Mt Morgans Gold Project.

The Korong intrusive belongs to the sanukitoid suite of evolved intrusive rocks comparable to the “Hemi-style” gold-bearing sanukitoid intrusions being developed by De Grey Mining Ltd (ASX:DEG)

Broad spaced shallow drilling also intersected numerous zones of strongly anomalous gold mineralisation (>0.1g/t gold), further confirming the intrusive targets are fertile and prospective for bulk tonnage gold mineralisation.

Analogous to De Grey’s Hemi-style intrusions 

Si6 (ASX:Si6) executive chairman Patrick Holywell says not only is it exciting that these targets have been discovered in a Western Australian region known for giant, intrusive related gold discoveries, but the Korong intrusive associated with rocks of the sanukitoid is particularly similar to De Grey Mining’s ‘Hemi-style’ gold bearing sanukitoid suite up in the Pilbara.

“Most people know how that played out,” he said.

“The results from this drilling also give the company confidence as we approach the upcoming phase 2 AC drilling program, which is set to begin at the end of April.”


Towards the end of 2021, Si6 started the first phase of AC drilling at Monument targeting intrusion related gold deposits.

This followed on from reverse circulation drilling at the Korong and Waihi banded iron formation hosted mineral deposits, where a 154koz inferred gold resource has been declared, along strike from Dacian Gold.

The program tested 26 out of 60 high-level targets comprising 126 holes for 4,198m.

Drill samples were submitted for gold and multi-element assay analysis, with the end of hole, fresh rock samples analysed for whole rock geochemistry to characterise rock type.

Spectral analysis to identify styles of alteration associated with intrusion related gold mineralisation were also requested.

Next on the list

Holywell says phase-2 drilling will focus on the high priority targets that have been identified at Monument, particularly the ones identifying as fertile intrusives such as ‘walk-up’ drill targets like Korong and Aermotor.

This will be carried out in addition to systematically testing the large number of regional, structural targets, which are obscured by transported cover and have seen little to no exploration to date.

Geochem sampling consisting of lag and fine-fraction soil sampling is also planned across untested intrusive targets with priority given to the poorly tested western edge of the McKenzie Well granitoid.
