CompanyInterestOwnership
Cadence Minerals Plc. 30 % Indirect
Hastings Technology Metals Ltd. (operator) 70 % Indirect
The greater Yangibana Project is comprised of tenements 100% owned by Hastings - and in part of tenements owned in a production joint venture, 70% owned and managed by Hastings and 30% owned by UK-AIM listed Cadence Minerals PLC (previously known as Rare Earth Minerals (REM)) through its subsidiary Mojito Resources Limited.

Most of the tenements within the project are held by Gascoyne Metals Pty Ltd, a 100% owned subsidiary of Hastings Technology Metals Ltd, and its wholly owned subsidiary Yangibana Pty Ltd.

Summary:

REGIONAL GEOLOGY
One of the key features of the Project area is the widespread occurrence of ironstone dykes that are spatially associated with the ferrocarbonatite intrusions.

The ironstone dykes are surrounded by relatively narrow haloes of fenitic alteration, and locally associated with quartz veining. Fenitic alteration haloes are characterised by the presence of feldspars and/or Naamphiboles and magnetite. The ironstone dykes consist predominantly of goethite, hematite, and magnetite, and are locally weakly radioactive.

The ferrocarbonatites and ironstones occur as sinuous pods and veins generally less than 10m wide, traceable cumulatively for up to 25 kilometres. The ironstones of the Gifford Creek Ferro-Carbonatite Suite (GCFS) have historically been the focus of exploration activity in the area due to enrichment in Rare Earths Elements (REE).

PROJECT GEOLOGY
Rare earths mineralisation at Yangibana is predominantly hosted by monazite, a phosphate mineral. Soon after acquiring its initial interest in the Yangibana Project Hastings identified that there is a significant difference between the rare earthsbearing monazite and the various deposits that form the Yangibana Project.

The belt of semi-continuous outcropping ironstone between Yangibana West and Kane’s Gossan hosts light rare earthsrich mineralisation dominated by Ce-monazite, whereas the ironstones at the other deposits and prospects host light rare eart ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Mining focus is high ore recovery and conventional drill and blasting methods will be employed.

The Project is comprised of three main rock types:
• The upper horizon is a saprolite, this does not require blasting.
• The lower weathered and fresh granite horizons require blasting.
• Ironstone (not all of which is ore), RC grade control drilling is required.

The ore dips at between 10 and 45 degrees and varies in thickness between 1m and 20m at Frasers and 1m and 30m at Bald Hill, with an average thickness of 4m. The ore zone (ironstone) is visually distinct from the host rock, providing some control for ore identification.

RC grade control drilling will be done on a 10m x 10m grid, prior to ore delineation.

Selective blasting and mining around the ore zones are designed to remove the hanging-wall as cleanly as possible to expose the ore.

The ore is then mined to the footwall contact using selective mining. Due to the high value of the ore, a high ore recovery is the focus of mining. As such, a 50cm skin of dilution is added to the ore mined to enable a 98% ore recovery assumption.

The ground water at Frasers has a pre-mining static level at 309 metres reduced level (mRL) is 45m below the mining surface and at Bald Hill the pre-mining static level is at 309 mRL and is 45m below the mining surface. Pits will be dewatered ahead of mining using bores to provide a dewatered rock mass at no more t ........
