Astral Resources (ASX:AAR) is expecting to complete Theia Deeps drilling in the March 2027 quarter after returning a record 1,146.3 grams per tonne gold assay.
The record result comes from three diamond holes totalling 1,796.5m at the Theia Deposit, which hosts 1.4 million ounces of gold. Theia is part of the wholly owned Mandilla Gold Project, 70km south of Kalgoorlie in Western Australia.
Hole AMRCD468A returned 31m @ 13.47g/t gold (Au) from 288m, including 0.34m @ 1,146.3g/t Au from 305.57m. The company says this is the ‘highest-grade’ assay at the project.
AMRCD515 intersected 40m @ 3.3g/t Au from 332m, including 0.3m @ 317g/t Au, alongside 111m @ 1.12g/t Au from 424m, which sits below the April 2026 mineral resource estimate (MRE) pit shell.
Meanwhile, AMRCD514 returned 38m @ 0.84g/t Au from 572m and 2m @ 16.5g/t Au from 434m.
Managing Director Marc Ducler says the combination of ‘high-grade’ intercepts and broad mineralised zones highlights the scale of the Theia system and its ability to support further resource growth.
“The Theia Deeps drill program has delivered high-grade individual assays along with broad zones of gold mineralisation, reinforcing the potential to grow the current resource,” Ducler says.
The program now covers 25 holes for 13,400m, with six holes remaining to reach 60m x 60m spacing within the main mineralised pipe. Assays are pending for AMRCD516 and AMRCD575, and AMRCD615 is drilling.
The diamond rig will move to Kamperman at Feysville in early December for six holes totalling about 1,800m. Theia Deeps resumes in January 2027, while the Spiders reverse circulation program at Spargoville is delayed to early 2027.
