About Awati and the Tibooburra Gold Project
Awati was established with the principal objective of exploring for and discovering high-value mineral deposits, resulting in an early focus on high-grade gold systems located near Tibooburra in north-western New South Wales.
The 1,930km2 Tibooburra Gold Project comprises a contiguous land package of 10 granted exploration licences located approximately 200km north of Broken Hill. It stretches 160km south from the historic Tibooburra Goldfields, along the gold-anomalous (soil, rock and drilling geochemistry, gold workings) New Bendigo Fault, to where it merges with the Koonenberry Fault, and then strikes further south on towards the recently discovered Kayrunnera gold nugget field. The area is conveniently accessed via the Silver City Highway, which runs N-S through the project area.
Auriferous quartz vein networks and alluvial deposits that shed from them, were mined in shallow pits, shafts and adits by early prospectors between 1881 and 1901. Over 1,700kg of gold was extracted, mostly from alluvial and eluvial deposits. Despite the rich rock-chip gold assays and overall historical mining grades of over 20g/t Au, the primary ore systems have rarely been tested below the water table (approx. 60m). Only sporadic exploration has been conducted since the abandonment of the goldfield in 1901, with undercover exploration utilising the high-quality geophysical datasets of the Geological Survey of NSW (”GSNSW”) now being possible.
Similarities to the Victorian Goldfields
After a detailed study of the Tibooburra District, GSNSW geoscientists (Greenfield and Reid, 2006) concluded that ‘mineralisation styles and structural development in the Tibooburra Goldfields are very similar to the Victorian Goldfields in the Western Lachlan Orogen’. In their detailed assessment and comparison, they highlighted similarities in the style of mineralisation, mineral associations, metal associations, hydrothermal alteration, structural setting, timing of metamorphism and the age of mineralisation, association with I-type magmatism, and the character of the sedimentary host rocks. Mineralisation in the Tibooburra Goldfields is classified as orogenic gold and is typical of turbidite-hosted/slate-belt gold provinces (Greenfield and Reid, 2006).

Reported assays in yellow are from the recently completed RC Programme at New Bendigo. Note the fault is inferred and further drilling is required to delineate mineralisation proximal to the fault.
