Saturn Metals (ASX: STN) announced that the ongoing RC drilling at Apollo Hill Gold Project in the Western Australian goldfields has returned high-grade intersections.

Highlights include 5m @ 32.6 g/t Au from 301m, including 3m @ 54.2g/t Au from 301m within, 9m @ 18.2g/t Au from 301m – AHRC0362 (Apollo Hill main lode); 9m @ 1.48g/t Au from 276m – AHRC0363 (Apollo Hill hanging-wall intercept); and 5m @ 1.97g/t Au from 191m – AHRC0162 re-entry (Apollo Hill main lode).

Apollo Hill project

The Apollo Hill Project is located in the heart of the world-class Eastern Goldfields district in Western Australia, approximately 650km NE of Perth. It’s located approximately 50km SE of the gold mining and processing town of Leonora.

The Apollo Hill Project comprises of 20 highly prospective gold exploration and prospecting licenses (approximately 1,000km² of ground), two mining leases and two water exploration leases.

The Apollo Hill project comprises two deposits: The main Apollo Hill deposit in the north-west of the project area, and the smaller Ra Deposit in the south. Gold mineralisation is associated with quartz veins and carbonate-pyrite alteration along a steeply north-east dipping contact between felsic rocks to the west, and mafic dominated rocks to the east. The combined mineralised zones extend over a strike length of approximately 1.4km and have been intersected by drilling to approximately 350m depth.

The Project’s major asset is the Apollo Hill 2018 JORC Compliant Indicated and Inferred Mineral Resource of 24.5 Mt @ 1.0g/t Au for 781,000 ounces of gold using a cut-off grade of 0.5g/t Au (maximum depth of the resource at 180m below surface).

RC drilling at Apollo Hill

The company had recently commenced reverse circulation (RC) drilling at the Apollo Hill deposit within its 100%-owned Apollo Hill Gold Project, 60km from Leonora in the Western Australian goldfields.

This drilling at Apollo Hill is a key part of the Company’s strategy to grow the Project’s 781,000oz Mineral Resource. STN said that a further resource upgrade is targeted for late 2020, incorporating results from drilling conducted since November 2019.

Previous results from Apollo Hill hanging-wall

Previous results from the reverse circulation at the Apollo Hill hanging-walls reported on 10 July 2020 included high-grade assays of 6m @ 6.23g/t Au from 246m – AHRC0360; 13m @ 1.39g/t Au from 157m – AHRC0358; 4m @ 3.23g/t Au from 141m – AHRC0357; and 1m @ 24.10g/t Au from 70m – AHRC0357.

STN has now announced further results from the ongoing RC drilling at Apollo Hill.

High-grade intersections from Apollo Hill

Saturn Metals announced that the ongoing RC drilling at Apollo Hill has returned significant new intersections including 5m @ 32.6 g/t Au from 301m, including 3m @ 54.2g/t Au from 301m within, 9m @ 18.2g/t Au from 301m – AHRC0362 (Apollo Hill main lode); 9m @ 1.48g/t Au from 276m – AHRC0363 (Apollo Hill hanging-wall intercept); and 5m @ 1.97g/t Au from 191m – AHRC0162 re-entry (Apollo Hill main lode).

The complete drill results are shown in the table below.

Highest grades from AHRC0362

The company noted that the AHRC0362 result is amongst the best intersections seen to date at Apollo Hill, and contains the highest-grade individual assay ever returned from the project being 1m @ 128.5g/t Au from 301m.

The company said that visible gold was also noted in association with high grades in the 3m @ 54.2g/t Au intercept in hole AHRC0362. STN said that the AHRC0362 intersection sits in an underexplored portion of the Apollo Hill footwall at the southern end of the deposit and represents an exciting new opportunity for follow up exploration.

Further drilling completed

STN said that further drilling has been carried out around this high-grade zone with assays pending for an additional four holes.

Intersections extend hanging-wall mineralisation

The company reported that other intersections, including 9m @ 1.48g/t Au from 276m in AHRC0363, on the same drill section as the high-grade AHRC0362 result, continue to extend hanging-wall mineralisation.

Paving way for gold resource growth

Saturn Metals noted that the reported intersections sit outside the current Mineral Resource of 24.5 million tonnes grading 1.0g/t Au for 781,000 ounces of gold and highlight the potential to increase the size and quality of the Apollo Hill gold system.

What’s next?

Saturn Metals said that the high-grade intersections with visible gold at Apollo Hill have resulted in the company uncovering a new opportunity for follow-up exploration.

STN announced that further work will include infill, step out, and twin-hole drilling. The company said that this work will be designed to improve confidence in, and test potential extensions to the current resource estimates.

The company noted that the Apollo Hill Project has the potential to become a large tonnage, simple metallurgy, low strip open pit mining operation.

Management comments

Saturn Managing Director Ian Bamborough said: “The latest assay results continue to highlight the potential to improve both the scale and quality of the Apollo Hill gold system. Drilling is continuing on multiple fronts across the deposit. Assays remain pending for several important holes around this exciting new footwall zone and we look forward to reporting on the results in due course.”
