Red River Resources demonstrates exceptional gold grades up to 130 g/t at Hillgrove project’s Sunlight Lode

The Sunlight Lode mineral resource is 680,000 tonnes at 8% gold and 0.3% antimony and is open down plunge and to the southeast

Red River Resources Limited (ASX:RVR) has confirmed high-grade gold mineralisation in sampling results taken from the Sunlight Lode, part of its Hillgrove Gold-Antimony Project in New South Wales.

Results from initial metallurgical test work on a bulk sample also demonstrate the presence of gold.

Abundant visible gold

The Sunlight Lode system was sampled where it is exposed in Sunlight cross cut 2, an area of historic mining in the upper levels of the lode.

Abundant visible gold was noted in the sampling, with a peak assay of 0.95 metres at 130 g/t gold recorded.

The 20-kilogram bulk sample taken for metallurgical test work was submitted to Consep Pty Ltd in September 2017 .to enable modelling of a gravity circuit.

The bulk sample had a calculated head grade of 122 g/t gold, with 84.2% of gold present as gravity recoverable gold

Gravity recoverable gold is the portion of gold in the ore that can be feasibly recovered by gravity concentration.

Remaining non-gravity recoverable gold is the portion which is too fine or inadequately liberated at the finest viable grind size to be recovered by gravity concentration.

Potential for high-grade gold extensions

Sunlight Lode has a gold dominant mineral resource of 680,000 tonnes at 8 g/t gold and is open both down plunge and along strike to the southeast.

Red River believes there is potential for high-grade gold extensions to known mineralisation.

The deepest hole drilled confirmed the lode was high-grade and open at depth, intersecting 22.95 metres at 4.5 g/t from 392.65 metres.

This includes 3.3 metres at 7.2 g/t from 394.2 metres and a narrow high-grade intersection of 0.2 metres at 220 g/t gold from 415 metres.

Multiple processing circuits

Hillgrove is about 30 kilometres from Armidale in NSW and includes a 250,000 tonne-per-annum processing plant currently on care and maintenance.

The plant comprises a selective flotation circuit (capable of producing antimony-gold and refractory gold concentrates), an antimony leach-electrowinning-refining and casting plant, a gold-cyanide leach circuit with gold room and a pressure oxidation circuit.

Infrastructure supports near-term exploration and development restart

All mine infrastructure to support a near-term restart of exploration and development activities, such as ventilation, electricity and water, are in place.

The Cox’s Lode decline is connected to the Syndicate decline with only 40 metres additional development required from the Cox decline to begin the potential first Sunlight Lode ore drive.

The Sunlight exploration decline was recently development by the previous owner to provide droll platforms to target extension of the lode at depth.
