Yandal Resources Ltd (ASX:YRL) has demonstrated the continuity of mineralisation along strike at the Siona discovery, part of the Ironstone Well-Barwidgee (IWB) Gold Project in Western Australia.
The company’s infill reverse circulation (RC) drilling hit gold over a 300-metre strike, generating results including 17 metres at 4.9 g/t gold from 85 metres, including 1 metre at 61.9 g/t and 6 metres at 12.8 g/t.
YRL observed visible gold within the RC chips in several holes, indicating potential for zones of high-grade mineralisation within the system.
“Excellent” early results
“Siona infill RC drilling continues to demonstrate mineralisation continuity along strike and has extended mineralisation beyond the extent of discovery holes 24IWBRC0039 and 24IWBRC0044,” Yandal Resources managing director Chris Oorschot said.
“Mineralisation is now confirmed along more than 300 metres of strike.
“It is also encouraging to see higher-grade intercepts across Siona, which are supported by the observation of visible gold.
“Given the structural nature of the orogenic gold systems, higher-grade zones are likely, and to see evidence of such at this early stage is an excellent result.
“Heavy rainfalls across the project area have resulted in a pause in current RC drilling.
“However, this will give the Exploration Team time to consolidate results and prepare for drilling to re-commence in early 2025.
“The Exploration Team is looking forward to continuing to testing structural and geochemical targets proximal to Siona in the new year.”
Drilling to resume in 2025
Other gold results of note from this program include:
- 23 metres at 1.3 g/t gold from 102 metres, including 15 metres at 1.6 g/t from 105 metres; and
- 43 metres at 0.4 g/t from 93 metres.
YRL intends to resume RC drilling early in 2025, testing structural targets and regolith anomalies close to Siona along the eastern margin of the New England Granite contact to understand the broader mineralisation potential across the large-scale target area.
The exploration team will also begin collecting geochemical data to better understand the characteristics of the mineralisation at Siona, with planning for geophysical exploration including detailed ground gravity and passive seismic surveys underway.
Upcoming activities
Yandal has a very active end of 2024 and start of 2025 scheduled with exploration activities and news flow, including:
- Further results from the follow-up RC drilling across Siona will continue to be received over the coming weeks;
- Aircore drilling results from across the Caladan and Irulan target areas are anticipated in four weeks;
- Diamond drilling at Siona is scheduled to commence in January 2025;
- RC drilling will re-commence across the New England Granite in January 2025; and
- Results from the second phase of soil sampling covering the broader Caladan target have been received and will be released once processing and interpretation are complete.
