Astral shines with gold results up to 133.25g/t Au at Mandilla

Perth-based gold and base metals exploration company Astral Resources (ASX:AAR) has delivered more ‘high-grade’ gold results through reverse circulation (RC) drilling at the Theia and Eos prospects located within the Mandilla Gold Project in Western Australia.

The company reports RC and diamond drilling at Mandilla is ongoing with 11 diamond holes for 2,773.4m, and 98 RC holes for 15,008m have been completed with assays for 52 holes currently pending.

At Theia, Astral says diamond hole MDRCD660 intersected ‘significant’ gold mineralisation with over 250 gram x metres of gold accumulated across several intersections. Best assays from this hole include 44.3m @ 1.89g/t Au from 392m including 0.5m @ 133.25g/t Au from 420.85m, as well as 25.3m @ 1.12g/t au from 287m including 1m @ 19.69g/t Au from 299m.

Our decision to focus on continuing to grow the resource base at Mandilla … is well supported by these latest results”

MDRCD660 also recorded 38.6m @ 2.10g/t Au from 189m including 0.4m @ 71.70g/t Au from 190.2m, 0.5m @ 30.33g/t Au from 222.8m, and 0.5m @ 46.57g/t Au from 227.1m.

The company says the newly identified mineralisation of 38.6m @ 2.10g/t Au from 189m strengthens the current interpreted ‘high-grade’ zone within the pit shell while a second ‘significant’ zone of gold mineralisation towards the bottom of the hole, 44.3m @ 1.89g/t Au from 392m, highlights additional mineralisation beyond the current resource limits.

Other ‘significant’ results recorded at Theia include hole MDRCD661 with 2m @ 16.38g/t Au from 86m and 7m @ 1.85g/t Au from 94m; and MDRCD681 with 4m @ 3.33g/t Au from 246m.

Astral reports MDRCD681 was drilled behind MRDCD660, and notes the frequency of quartz veining in MDRCD681 was observed to be less than for MDRCD660. However, galena, quartz veining, and visible gold were still observed in the diamond core which demonstrates the continued presence of gold mineralisation.

The company notes in both instances where visible gold was observed in core, the gold was located on the non-sample side of the core sample, which resulted in assay results that potentially do not reflect the actual grade of gold present.

Astral reports this phenomenon is not isolated to this particular hole, and notes the grade of the deposit at Theia has potential to increase with increased drilling.

Commenting on the results, Astral Resources Managing Director Marc Ducler said: “These latest results highlight 2 significant developments at the Mandilla Gold Project.

Firstly, hole MDRCD660 has demonstrated a significant extension of gold mineralisation at depth at the Theia deposit, with several intersections accumulating in over 250 gram metres of gold over the length of the hole. With a significant portion of the higher grade mineralisation situated beyond the current mineral resource we have confidence that further drilling will provide us with the continued resource growth required to drive the project forward.

Secondly, testing for bedrock gold mineralisation associated with the high-grade Eos palaeochannel deposit has returned positive results, with the identification of a broad zone of gold mineralisation associated with a demagnetised zone believed to represent a possible shear zone. This confirms a new bedrock target zone requiring further drill testing.

Our decision to focus on continuing to grow the resource base at Mandilla to reach the critical mass required to support a robust standalone mine development is well supported by these latest results. With further results pending and follow-up drilling planned we are increasingly confident that we now have one of the best undeveloped gold projects in the Eastern Goldfields of Western Australia.

With RC and diamond drilling progressing at Theia and a further reduction in the turnaround times for assay results being experienced, we expect to be providing further exploration updates in the coming weeks, as well as news from project studies that have kicked off.”

At Eos, Astral reports 3 RC holes were drilled to test below the palaeochannel deposit for fresh rock gold mineralisation within the Emu Rock Granite. The company notes that gold mineralisation at Theia was first identified within a ‘high-grade’ paleochannel, which then led to the discovery of a ‘significant’ fresh rock Mineral Resource Estimate (MRE) associated with demagnetised granted within the Emu Rocks Granite, which is currently 24 million tonnes @ 1.1g/t Au for 878,000 ounces of contained gold.

Of the 3 holes drilled, the best result was the identification of a broad zone of gold mineralisation, with hole MDRC716 returning 26m @ 0.69g/t Au from 93m. Astral says it is too early to tell whether a ‘significant’ primary target is present at Eos, however it notes this is a ‘strong’ basis to continue to evaluate this opportunity.

The company says further drill testing will be planned in due course.

Astral Resources is a Perth-based gold and base metal exploration company focused on its portfolio of projects in the Kambalda-Kalgoorlie region of Western Australia. These projects include the Mandilla, Feysville, and Carnilya Hill projects.
