The acquisition of a significant proven sapphire resource with existing mine infrastructure and straightforward alluvial mining will enable Richland to bring Nardoo back into production within 9 months. While first production can be achieved through a mine restart, Richland has identified Nardoo as having the capacity for significant scalability in terms of sapphire production. Mining of the current JORC (2004) delineated resource can be increased through low cost exploration at prospective targets within the licences.
The deposit has a large blue colour resource and it also produces yellow and green and parti-colour material which would be of interest for the growing fancy colour industry. While the Nardoo resource does contains special large stones, Richland believes that the strength of the resource is in supplying sapphires of verifiable origin in large quantities in the sizes, grades and colours used by the international jewellery market.
Geological Setting and JORC Resource
This deposit lies within the Queensland Sapphire Gemfields, located near the township of Sapphire in Central Queensland. In total the project tenements (mining leases 70419 & 70447) cover approximately 494 hectares of potential sapphire-rich alluvial placers within this known gemfield (see Figure. 1).

The two wholly owned mining leases have a JORC (2004) measured resource of 109 million carats of sapphire. The JORC (2004) resource was based on Calweld drilling (1 metre plus wide diameter rig capable of measure significant volumes of material near to surface), and bulk sampled in 1991 and later by infill drilling in 2004. An alluvial placer area of 115ha was identified that contained an estimated 22 million grams (109 million carats) at an average grade of 8g/LCM on the original Australis mining leases. As part of the JORC (2004) resource an average grade of 8 g/LCM was calculated from drilling and bulk sampling of the mining leases. These tenements originally covered an area of approximately 390ha and comprised mining leases 70004, 70005 and 70006. These mining leases are now encompassed and replaced by mining leases 70419 & 70447
