Red River Resources Ltd (ASX:RVR) (FRA:R1R) will start drilling at its Hillgrove Gold Project in northern New South Wales when a diamond drill rig arrives in mid-July, as it moves to recommence gold production by the end of the year.
A 14-hole program of 1,310 metres will comprise an initial eight-hole program of 690 metres targeting shallow high-grade gold mineralisation in the upper levels of the Eleanora Lode.
Once this is completed, the drill rig will move to the Curry’s Block target to complete a six-hole, 620-metre program where surface sampling carried out by Red River has defined extensive high-grade gold-antimony mineralisation.
The Curry’s Block drilling will be partially funded by a grant from round three of the NSW Government New Frontiers Cooperative Drilling Grants Program.
"Exciting" to start drilling
Red River managing director Mel Palancian said: “It is exciting to start drilling at Red River’s Hillgrove Gold project, as we move towards restarting gold production at Hillgrove by the end of 2020.
“We look forward to reporting the drill results as they come to hand as we work on building our existing gold inventory for the project.”
Hillgrove Gold Project, 23 kilometres east of Armidale, has an existing JORC 2012 mineral resource of 3.0 million tonnes at 4.9 g/t gold and 1.6 % antimony with a 250,000 tonnes per annum processing plant on active care and maintenance.
Eleanora Garibaldi Lode
The Eleanora Garibaldi Lode is one of the major mineralised structures at the Hillgrove gold project, with a strike extent in excess of 1.1 kilometres, with a northwest vertical to sub-vertical dip and an average thickness of two metres.
The Eleanora Garibaldi Lode is open at depth with the deepest hole ELG104 intersecting 9 metres at 3.6 g/t gold equivalent .
Mining activities (1986-1997) carried out by New England Antimony Mines targeted a number of high- grade antimony rich ore shoots, leaving behind the gold-rich but antimony poor areas of the lode system.
Historical sampling and reverse circulation drilling have indicated the potential to define a shallow high-grade gold resource within close proximity to the Hillgrove Mill.
The drilling program is expected to take around 20 days to complete.
Red River has a JORC 2004-compliant mineral resource for Eleanora Garibaldi Lode and is working to convert this into a JORC 2012-compliant mineral resource with the planned drilling.
Curry’s Block prospect
Red River geologically mapped and sampled the Curry’s Block prospect in October 2019 and the historic mine workings in the area were found to be far more significant than previously thought.
The highest grades obtained from the sampling program were 48.9 g/t gold, 10.55% antimony and 8.8% tungsten.
Red River believes that the Curry’s Block prospect has great potential, with a strike length of about one kilometre, mineralisation at surface, multiple mineralised lodes and high-grade gold, antimony and tungsten mineralisation present in historic workings and waste dumps.
Curry’s Block is on the Hillgrove Plateau and is 3.3 kilometres from the Hillgrove processing plant.
Bakers Creek Stockpile
The company said a reconditioned Knelson gravity gold concentrator it had recently bought in the US had been delivered and the installation process would start shortly as part of the Stage One restart involving the processing of Bakers Creek Stockpile. Stage One is scheduled to commence at the end of 2020.
Stage Two, which involves the full restart of the underground mining operations is scheduled to commence at the end of 2021.
