Drilling Commences at Amy Clarke Gold Prospect

Highlights

• First-passair-core drilling has commenced at the Amy Clarke Gold Prospect, part of the Company's 100% owned Duketon Gold Project located 60 km north of Laverton, Western Australia.
• Approximately 200 holes will be drilled to blade refusal for up to 8,000m of drilling to test gold anomalism, typically above 8 ppb Au and up to 690 ppb Au, extending for at least 4 kilometres in strike length.
• This is the first of several regional first-passair-core drilling programs anticipated across GSN's extensive 450 km2 Duketon Gold Project as part of ongoing exploration plans.

GSN's Chief Executive Officer, Sean Gregory, commented:

"We are excited to be back in the field again with this latest drill program at Amy Clarke. Amy Clarke is a highly prospective gold prospect being only 3 km along strike from Regis' recently exhausted 322koz Erlistoun Open Pit Gold Mine. The drilling targets were defined after GSN's extensive data compilation and confirmed by a successful soil sampling program earlier this year. We anticipate this to be the first of several regional first-pass drilling campaigns across key areas of the many kilometres of mineralised trends that strike through our Duketon Gold Project tenure."

Amy Clarke Prospect - Target Definition

After acquiring tenement E38/3518 in 2020, GSN set about reviewing the historical data across the project. In amongst the expansive data set compiled, including 24,000 soil samples and 12,000 drill holes, two key pieces of information caught the eye of GSN geologists. The first of which was a 2014 regional MMI soil survey that identified an area of 2 km strike length with anomalous gold (>3 ppb) and silver (>7 ppb) named the Amy Clarke Gold Prospect (Figure 2). The second piece of information was a RAB program drilled by Sons of Gwalia Ltd in 1996. Most of this drilling was to the east of the anomalous area, however one 9m deep hole finished in 3m @ 340 ppb gold in a mineralised quartz vein (Figure 4; refer ASX Announcement 5/11/20).

GSN followed up earlier this year with a more detailed soil survey that expanded the gold anomalism as being typically above 8 ppb Au and up to 690 ppb Au and extends up to 4 kilometres in strike. Importantly, many of the pathfinder element anomalies, such as tungsten, arsenic and bismuth, are coincident with the gold anomalies supporting the theory that the gold source is nearby (Figure 3; refer ASX Announcement 28/9/21).

Nearby Gold Deposit Comparisons

The Amy Clarke Gold Prospect is only 3km directly along strike from Regis Resources Limited's recently exhausted 322koz @ 1.9 g/t Au Erlistoun Gold Mine (Refer ASX: RRL Announcement 18/1/11).

Furthermore, the largest gold deposit in the Duketon Greenstone Belt, Regis' 2.1Moz @ 1.4 g/t Au Garden Well Gold Mine, was discovered on the back of a soil anomaly of similar size and tenor (Refer ASX: RRL announcement 8/3/11).

Drilling Program

Approximately 200 holes will be drilled to blade refusal for up to 8,000m of drilling. Blade refusal is anticipated to be nominally 30-50m below surface depending on weathering depth and rock strength. The drill holes are planned on a 100m x 20-25m grid across the areas of gold and pathfinder anomalism delineated from the 2021 soil survey (Figure 4). The drilling will continue for about 2 weeks with assay results expected early in 2022.
