# Great Southern Mining Reports High-Grade Gold Hits at Amy Clarke Maiden drilling campaign at Duketon project confirms significant mineralization along a 4.7-kilometre corridor. - **Source:** [Sydney Morning Herald - Business](https://www.smh.com.au/rss/business.xml) - **Published:** 2026-10-19 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/3c23e0a3-e877-4694-9172-836969f37af7 ## Maiden Drilling Success Great Southern Mining completed an 18-hole, 2248-metre reverse circulation drilling campaign at the Amy Clarke prospect. Located within the Duketon gold project near Laverton, the program successfully intersected high-grade gold along a 4.7-kilometre mineralized corridor. These results validate previous aircore drilling data and confirm the prospect's potential for further resource development. ## Key Intercept Highlights The headline result featured 5 metres grading 6.71 grams per tonne gold from 51 metres, including a 3-metre core at 10.4 grams per tonne. Additional hits included 2 metres at 8.92 grams per tonne and an 8-metre interval at 1.44 grams per tonne. These intercepts demonstrate consistent mineralization across the target area. ## Geological Structural Context Gold at Amy Clarke is associated with quartz veining and disseminated or coarse pyrite. The prospect sits within a high-strain structural corridor near rock type contacts. These structures are currently modeled as steeply east-dipping, which is a classic geological setting for gold deposition throughout the Eastern Goldfields region of Western Australia. ## Strategic Operational Proximity The Amy Clarke prospect is located just 12 kilometres from the Garden Well processing facility owned by Regis Resources. Furthermore, it lies along the same structural trend as the Erlistoun open pit mine, which hosts a 320,000-ounce resource. This proximity to established infrastructure significantly enhances the economic viability of the project. ## Expansion of Mineralized Zones The recent drilling campaign extended mineralization down-dip by up to 50 metres and broadened known high-grade zones. Mineralization was observed from the surface in weathered horizons and extended into fresh rock at depth. The system remains open to the south, where limited drilling has been conducted, leaving substantial prospective ground largely untested. ## Broader Duketon Project Synergy These results complement the company's nearby Golden Boulder discovery, where historic production averaged 28.6 grams per tonne. Great Southern is currently awaiting assays from an additional 6000 metres of drilling at Golden Boulder and the Golden Boulder East trend. These combined efforts aim to consolidate the company's footprint within the Duketon Greenstone Belt. ## Future Exploration Roadmap Great Southern has initiated detailed geological and structural mapping alongside multi-element geochemistry to refine future targets. Planning is underway for follow-up reverse circulation and potential diamond drilling. Initial focus will be on open lodes in the northern section of Amy Clarke and the central portion of the 4.7-kilometre mineralized trend. ## Regional Mining Significance The Duketon Greenstone Belt is a prolific region where Regis Resources has identified over eight million ounces of gold. By securing tenure over major shear zones, Great Southern is positioning itself within a high-value neighborhood. The company continues to build a robust portfolio of prospects on the doorstep of significant regional mining operations. ## Sources covering this story - https://www.smh.com.au/business/companies/great-southern-uncovers-new-high-grade-hits-in-wa-gold-hunt-20261019-p616rk.html?ref=rss&utm_medium=rss&utm_source=rss_business — --- _Summary written by Brifing from the original reporting.
