AC DRILLING IDENTIFIES NUMEROUS INTRUSIVE GOLD TARGETS AT MONUMENT PROJECT, WESTERN AUSTRALIA
Highlights
-
Final results received from the geochemical drilling program exploring for prospective felsic intrusives across the ~300km[2] Monument Gold Project
-
End of hole multi-element assay data indicates 18 out of 26 targets drilled classify as fractionated, potentially fertile intrusives prospective for bulk tonnage gold mineralisation
-
The identified intrusives are analogous to those that host the Jupiter (1.5Moz) and Cameron Well (0.25Moz) deposits located in the neighbouring 2Moz Mt Morgans Gold Project owned by Dacian Gold Ltd (ASX:DCN)
-
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)
-
Importantly, the broad spaced shallow drilling also intersected numerous zones of strongly anomalous gold mineralisation (>0.1g/t Au), further confirming the intrusive targets are fertile and prospective for bulk tonnage gold mineralisation
-
High priority mineralised corridor over 4km long and 500m wide has now been identified along western margin of the Korong intrusive
-
Follow-up AC drilling testing high priority targets is scheduled for end of April.
Si6 Metals Limited ( ASX: Si6 or the Company ) is pleased to announce results from the reconnaissance aircore (AC) geochemical drilling program undertaken across its 100%-owned Monument Gold Project (MGP) located in the Laverton Tectonic Zone (LTZ), Eastern Goldfields, Western Australia. The MGP is located near six +2Moz gold deposits within a 75km radius, including the Granny Smith (~3Moz), Wallaby (~7Moz) and Sunrise Dam (10Moz) gold deposits. Recent and nearby discoveries by Dacian Gold Ltd (Dacian Gold, ASX:DCN) include Jupiter (~1.5Moz), Westralia (>2Moz) and Cameron Well (0.25Moz)(Figures 1 and 2).
Si6 Executive Chairman, Patrick Holywell stated, “We are highly encouraged by the results of the AC drilling program which successfully proved the presence of 18 potentially fertile gold intrusives among our 26 targets that are spread over a 30km strike at the Monument Gold Project. These intrusive targets are highly prospective for gold in a Western Australian region which is well known for giant, intrusiverelated gold discoveries. The Korong intrusive associated with rocks of the sanukitoid suite makes me quite excited as we know De Grey Mining has a similar suite up in the Pilbara and most people know how that played out!
“The results from this drilling also give the Company confidence as we approach the upcoming Phase 2 AC drilling program which is scheduled to begin end of April. Phase 2 is set to target the high priority targets that we have identified from the significant number of early and advanced stage intrusive prospects that we have now confirmed exist over the length of the Project.”

Program Details
During 2021, Si6 announced it had been successful in its application for co-funded exploration drilling through the Western Australian Department of Mines, Industry, Regulation and Safety (DMIRS) Exploration Incentive Scheme (EIS) program where a 50% refund of direct drilling costs are awarded for innovative drilling projects such as this latest drilling campaign.
Towards the end of 2021, Si6 commenced the first phase of AC drilling at Monument targeting intrusion related gold deposits (Phase 1). 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.
Phase 1 drilling aimed to map out the distribution of intrusive targets and identify those prospective for bulk tonnage gold mineralisation based on their multi-element geochemical signature. 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.
Targets identifying as fertile intrusives will be tested in the next round of aircore drilling (Phase 2). Phase 2 drilling is scheduled for the end of April and will prioritise prospective intrusive targets in addition to systematically testing the large number of regional, structural targets which are obscured by transported cover and which have seen little to no exploration to date.

Analysis and interpretation
Detailed interpretation of end of hole drill samples was undertaken using ioGAS[TM] software (ioGAS), an exploratory software tool specifically designed for mineral exploration. The software utilises mineral and elemental abundances to classify rock suites by comparing to known data sets which occur within ioGAS.
To classify rock type in ioGAS based on elemental abundances, a 1m end of hole sample comprising near fresh rock was collected and submitted to ALS laboratories for low-level gold assay and a four acid digest to completely dissolve all minerals. The analytical results were then loaded into ioGAS and elemental compositions and ratios plotted, analysed and compared to determine overall rock types. Low-level gold analyses consisted of aqua regia digest and fire assaying for end of hole samples with an ICP finish. Although the drilling did not specifically target gold mineralisation, a number of anomalous gold intercepts were encountered such as at Two Bills in the north of the project, Korong, McKenzie Well and Aermotor Well in the south, including 4m at 1.38g/t Au from surface (MOAC118), 4m at 0.44g/t Au from 36m (MAOC064) and 4m at 0.19g/t Au from 20m (MOAC118) (Figure 3).

Figure 3. End of hole whole rock geochemistry data classified using ioGAS software and location of significant intrusive bodies
The principal intrusive rock types identified from the study include granite, granodiorite, diorite and quartz-feldspar porphyry (felsic volcanic) with 64 out of the 126 holes drilled classed as felsic intrusives. The intrusives are spread over a 30km strike spanning the entire project and occur in 18 out of 26 of the targets drill tested (Figures 2 and 3). The identified intrusives are analogous to those that host the Jupiter (1.5Moz) and Cameron Well (0.25Moz) deposits located in the neighbouring 2Moz Mt Morgans Gold Project owned by Dacian Gold.
Two of the larger, outcropping felsic intrusive bodies, which are located in the southeast corner of the project area, have known resources nearby, including Korong (3Mt @ 1.4g/t Au for 139koz inferred) located west of the Korong felsic intrusive and Dacian Gold’s McKenzie Well (0.95Mt @ 1.10g/t Au for 34koz inferred – see ASX:DCN announcement 16 February 2021) located east of the McKenzie Well granite. Coincidently, both mineral deposits contain late-stage felsic intrusives within and are proximal to the mineralised zones (Figures 3 and 4).

Korong Intrusive Target
The Korong intrusive target consists of a 2km x 2km circular feature classified in ioGAS as a felsic granitoid intrusive and is located 2km southeast of the Korong gold deposit (3Mt @ 1.4g/t for 139koz Au inferred) where Si6 undertook a resource infill and extension drilling program in January 2021.
Analysis of the strontium (>500ppm Sr) and yttrium (<10ppm Y) in addition to silicon, magnesium, barium and (light rare earth) LREE elemental abundances indicate the Korong intrusive belongs to the sanukitoid suite of evolved intrusive rocks. A similar suite of sanukitoid rocks has been identified as the principal host lithology at De Grey Mining Limited’s (ASX:DEG) ~7Moz Hemi gold discovery in the Pilbara (see ASX:DEG June 2021). Typically, sanukitoids are mantle derived rocks and are commonly enriched in gold.
Anomalous gold mineralisation was intersected in broad, 320m spaced AC drilling along the western edge of the intrusive, which included a mineralised intercept of 4m @ 0.19g/t Au in hole MOAC118 from 24m. A field inspection of the mineralised intersection confirmed that the elevated gold mineralisation is associated with quartz veining hosted within a felsic granitoid intrusive. Shallow alluvial

cover and weathered granitoid comprising the top 4m of the hole further returned 4m @ 1.38g/t Au indicating gold is also being shed from a nearby source.
Broad spaced (400m north-south line spacing), historic drilling by Syndicated Metals Ltd (now Discovex Metals Ltd ASX:DCX) (Syndicated Metals) in 2017 along the southwest edge of the intrusive also intersected anomalous gold mineralisation, including 8m @ 1.06g/t Au, 4m @ 1.01g/t Au and 8m @ 0.66g/t Au (see Syndicated Metals’ ASX announcement 18 December 2017 “Multiple Zones of Shallow Gold Mineralisation Outlined in Aircore at Monument Gold Project, WA”). Mineralisation within the historic Syndicated Metals’ drill holes is hosted entirely within the granitoid intrusive, along the western contact and is also associated with late-stage felsic porphyries intruding mafic volcanics along strike towards the south.
The mineralised drill intercepts >0.10g/t Au hosted within the Korong felsic intrusive and associated porphyries extend to the south over a 1.7km strike length with mineralisation remaining open to the north as well. Scattered gold-in-soil geochemical anomalism >20ppb Au in this area also supports the gold in the drill holes. The target corridor which remains open northwards to Korong and southward to the Old Copper prospect extends for 4km. Much of this corridor is yet to be drill tested (Figure 4).
McKenzie Well Intrusive Target
McKenzie Well comprises an elongate, northwest trending intrusive body approximately 4km long and 2.5km wide and has been classified in ioGAS as a felsic granitoid intrusion with more fractionated dioritic phases. Elevated gold mineralisation was intersected in AC drilling at the north-western edge of the intrusive in hole MOAC027, with 1m @ 0.28g/t Au ending in mineralisation comprising quartz veining hosted within a mafic volcanic (Figures 2 and 3).
Very little exploration has been undertaken within and around the granitoid to date. Much of the focus has been at Dacian Gold’s adjoining McKenzie Well Prospect 400m to the east, where a maiden mineral resource estimate of 0.95Mt @ 1.10g/t Au for 34koz inferred was reported (see Dacian Gold’s ASX announcement on 16 February 2021). Similar to the gold mineralisation noted at Korong, gold mineralisation at the McKenzie Well prospect is extensively associated with late-stage felsic porphyries.
Other Intrusive Targets
In addition to the regional suite of granitoid rocks, AC drilling has defined late-stage dioritic and granodioritic felsic intrusives all the way from Aermotor located at the south end of the project to Two Bills in the north, a strike length of more than 30km . Most of these intrusives occur under cover and have seen little to no exploration to date.
Gold mineralisation intersected at Aermotor comprising 4m @ 0.44g/t Au from 36m (MOAC064) is contained within quartz veins hosted within a mafic volcanic in contact with black shales. Drilling in this area is very broadly spaced with collars 320m apart. Although the AC drilling did not intersect a felsic intrusive body, the magnetic interpretation suggests an intrusive body remains below the current level of drilling which does not extend beyond 50m vertical depth.
Gold mineralisation at the Two Bills prospect in the north of the project area comprising 4m @ 0.052g/t Au from 32m (MOAC084) and 4m @ 0.056g/t Au from 40m (MOAC085) hosted within sheared basalt and ultramafics located along the eastern contact of felsic porphyry and granitoid. This framework setting is very similar to Korong and McKenzie Well with a major shear structure traversing the edge of a potentially fertile granite intruded by late-stage porphyries (Figure 3).
ASX Announcement
Based on the evidence from gold mineralisation observed at the Korong and McKenzie Well intrusives, the outer edges of these additional intrusives bodies are highly prospective for gold where they have been subjected to brittle deformation and shearing in addition to brittle deformation and fracturing along internal structures within the intrusive bodies themselves, which is evident at the Wallaby (7Moz) and Jupiter (1.5Moz) deposits.
Exploration Focus 2022
The EIS-funded AC drilling program has outlined a large number of early and advanced stage intrusive targets over the full length of the Monument Gold Project. Broad-spaced drilling associated with elevated gold mineralisation in structure corridors proximal to and wholly within the intrusives has highlighted that the intrusive bodies and adjoining structures are fertile for gold. Based on the level of knowledge from known intrusion related gold deposits within the LTZ, this discovery is regarded as significant with this style of gold mineralisation remaining the Company’s primary focus.
Korong and Aermotor are high priority “walk-up” and drill targets and will be prioritised in the upcoming Phase 2 AC drill program which is scheduled for end of April. 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.
At the Korong intrusive, the Company is in the process of de-archiving and purchasing historic IP data that was collected along the western edge of the intrusive by Terra Resources Pty Ltd in 2011. Once the data has been retrieved, the Company will engage Southern Geoscience Consultants (SGC) to reinterpret the data and advise on extending the survey across the full length of the intrusive and over sections of the 4km corridor. In addition, a SAM survey (Sub-Audio Magnetics) is planned for the KorongOld Copper mineralised corridor to better define structures responsible for controlling gold mineralisation and targets for future drilling programs.
