100% owned ~1,600km2 South Stirling Project | |
➢ ASQ's first drill hole at the South Stirling Project, aircore hole SS001 | |
designed to check the validity of an anomalous historic drillhole | |
use | confirms the previous result and extends the thickness of the |
anomaly | |
➢ SS001 intersections: | |
• 12m from 26m @ 0.70% Ni and 0.06% Cu, within; | |
• 21m from 21m @ 0.58% Ni and 0.06% Cu | |
personal | ➢ Maximum values of 9,237ppm (0.92%) Ni from 28-30m and |

Australian Silica Quartz Group Limited (ASX:ASQ, 'ASQ' or 'the Company') provides the following update on the Company's exploration activities at its 100% owned South Stirling Project in the Southwest of Western Australia.
Background
ASQ has established the South Stirling Ni/Cu Project by way of four exploration lease applications lodged covering 1,603 km2 over the Albany Fraser Mobile Belt, South-Western WA where the Company has identified a historic end of hole aircore drilling assay with anomalous nickel and copper that was never followed up. ASQ considers the application area has potential for Nickel-Copper magmatic sulphide mineralisation associated with mafic-ultramafic intrusions emplaced into granulite facies country rocks. (Refer full detail in the 23 September 2020 ASX announcement Exploration Update).

Aircore Drilling
The company recently twinned the anomalous historic drillhole completed by Iluka Resources Limited ("Iluka") by way of a single vertical aircore hole SS001 (Figure 2). The Iluka hole (W00324) returned an end of hole assay of 1.5m at 0.79% Ni, 934 ppm Cu from 28.5m. Iluka recorded the rock type as saprolite suggesting fresh basement rocks had not been reached. ASQ's SS001 was terminated at 52m due to difficult drilling conditions prior to intersecting fresh basement rock.
The encouraging assay results from SS001 are presented in Table 1 and include intersections; 12m from 26m
- 0.70% Ni and 0.06% Cu, within 21m from 21m @ 0.59% Ni and 0.05% Cu with maximum recorded values of 9,237ppm (0.92%) Ni from 28-30m and 1,007ppm Cu from 38-42mconsistent with the previously reported Iluka result.

Petrography and mineralogy descriptions of selected drill chips show the mineralisation to occur in nickeliferous siderite with common evidence of concentrations of predominantly weathered Ni/Cu/Fe sulphide minerals. The association of siderite with sulphides is thought to be highly unusual and although the exact style of mineralisation is not known, it is likely the mineralised zone represents transported or in situ material formed within a local structural boundary such as the nearby WSW/ENE orientated major fault mapped by the Geological Survey of Western Australia (Figure 2).
The indication that significant concentrations of nickel and copper are present and may be associated with the numerous linear structures found within the project area is encouraging and potentially points to the faults acting as conduits for the movement of metals from any sulphide rich intrusions present within the basement sequence.
ASQ's drilling was limited to the road reserve due to land access restrictions where it was possible to twin the anomalous Iluka hole. ASQ will continue efforts to establish neighbouring land access in order to further assess this anomaly.

Program Planning
ASQ commissioned exploration industry consultants Newexco Exploration Pty Ltd to complete reviews of the existing surface geochemistry and geophysics data and assist with target generation for the South Stirling Project.
Newexco applied an advanced magnetic and radiometric processing suite to the South Stirling dataset in order to better delineate magnetic source rocks that may represent mafic intrusions. These interpreted intrusions have been prioritised against the surface geochemistry data yielding a number of areas that justify further work (see Figure 4).
Five areas totalling ~770km2 have been identified as a priority for airborne electromagnetic surveying (see Figure 3). Planning is underway to complete this work later in 2022. Additional areas that require ground truthing by surface sampling will also be assessed in H2 2022.
Any bedrock conductors identified by the AEM will be confirmed by ground electromagnetics surveys following establishment of land access and prior to drill testing.
Project Partners
ASQ is actively seeking joint venture partners for strategic involvement in the South Stirling Project. With +100km in length of the Albany Fraser Mobile Belt - Biranup Zone secured by +1,600km2 of 100% owned tenements, the scale and prospectivity of the Project presents a rare opportunity for a motivated group to get involved. Discussions are underway with several well credentialed parties who have expressed an interest in earning into the project by way of funding the exploration ASQ plan to carry out or by undertaking the exploration themselves.
