GoldArc Resources (ASX:GA8) has defined two gold mineralised corridors extending for more than 600m at its Yttria prospect in Western Australia’s Eastern Goldfields.
The corridors were identified through a maiden 363-hole aircore drilling program comprising 11,010m and remain open to the south. Both sit outside Yttria’s existing rare earth element (REE) mineral resource.
Representative results, reported using a nominal 0.1 grams per tonne (g/t) gold (Au) lower cut-off, include: 11m @ 0.330g/t Au from 32m in YAC172, 4m @ 0.950g/t Au from 16m in YAC341, 4m @ 0.609g/t Au from 20m in YAC174, 4m @ 0.522g/t Au from 20m in YAC131, and 4m @ 0.506g/t Au from 12m in YAC190.
The reconnaissance program covered an area of about 1.4km by 1.2km across 14 drill lines spaced between 80m and about 200m apart. Holes averaged 27.6m deep and were drilled to refusal.
GoldArc targeted broad, low-grade gold anomalies identified through historical vacuum and reverse circulation drilling originally focused on REE, yttrium, and scandium mineralisation.
Yttria, part of the company’s Leonora North Gold Project, hosts a mineral resource of 15 million tonnes @ 490 parts per million total rare earth oxides.
Managing Director Paul Stephen says the program represents the first systematic test of Yttria’s gold potential.
“This 11,000m aircore program is our first systematic test of gold potential at Yttria, and it has already located two mineralised corridors over 600m long, each open to the south,” Stephen says.
“We are encouraged by the scale of what we are seeing across the drilled area, and we will now test it with closer-spaced RC drilling.”
The company reports mineralised holes coincide with arsenic and tungsten pathfinder anomalism similar to that associated with its nearby 137,000-ounce Mt Stirling gold deposit.
GoldArc plans to follow up the Yttria targets with RC drilling after completing an approximately 5,500m campaign scheduled to begin at Mt Stirling in early August 2026.
