Drilling to Commence at Tambourah, Pilbara WA Targeting Known 12km Gold and Copper Trend

Highlights

• A drilling program to validate and expand historical exploration results has been designed at the Hawkstone Prospect, part of RGL's 100% owned Tambourah Project.

• The Hawkstone Prospect is in the centre of a 12km gold and copper trend where priority targets contain historical drilling and surface sampling (Figures 2 and 3) with[1] :

  • Drill intercepts including 30.5m at 1.1% Cu; and

  • High-grade rock chip results up to 21.78% Cu and up to 3.6 g/t Au.

• This will mark the first exploration drilling for some 55 years, in an area where the historical drilling was never assayed for gold.

• Drilling approvals are in place and timing for commencement of drilling is expected to be early March.

David Lenigas, RGL’s Chairman, stated:

“We are very excited to be back on the ground at our Tambourah Project now that the summer exploration hiatus is coming to an end. We have instructed our consultant geological crews to execute our designed drill program and we look forward to testing this large, relatively unexplored, copper and gold trend, which has seen no drilling since the 1970-1971 campaign, some 55 years ago. Historically, our focus here was on the lithium outcrops in the north, however we are very optimistic that this drill program will finally open up Tambourah's significant gold and copper potential. We are aiming to be drilling here in early March."

Riversgold Limited (ASX: RGL, RGLO, “Riversgold” or “the Company”) is pleased to announce that an exploration drilling program, designed to optimally target the anomalous gold and copper trend within the Hawkstone Prospect, is now being finalised at Tambourah and handed to the Company's exploration consultants at Apex Geoscience for imminent execution.

The Project, Figure 1 , is situated ~160km southeast of Port Hedland and comprises three granted tenements (100% RGL) that cover ~110km[2] .

Access to the Tambourah Project is excellent via the Great Northern Highway and the Hillside-Woodstock Road that passes straight through the Project itself.

Strategically, the Project is situated ~100km to the southwest of the 2.4Mtpa CIL Processing Plant at the Warrawoona Gold Project and ~120km east of the Golden Eagle Processing Plant at Nullagine ( Figure 1).
