Kimberley Diamond Projects
Aries Diamond Project
The Aries Diamond Project is located approximately 30 kilometres southeast of the Mt Barnett Roadhouse in the Central Kimberley, approximately 240 SW of the Argyle Diamond Mine and 250km east of Derby.
The Aries kimberlites were first discovered in 1986 and since then multiple campaigns, focusing on the near surface outcrop, have been undertaken by other explorers. The Aries Kimberlite Complex has been mapped at surface with a footprint over 10Ha, making this the largest known diamond bearing kimberlite complex in Western Australia.
In 2005 a wide diameter “Bauer” drill program for bulk sampling processed 2,169 tonnes, recovering 181 diamonds for 25.34 carats (WAMEX Report A72519). A best grade of 4.9cpht (carats per hundred tonnes) was achieved in the Athena Pipe.
Odessa conducted a gravity survey in 2022 which showed a significant increase in the footprint of Aries and additional Gravity anomalies suggesting potential for 14 new undiscovered Kimberlites.
The image above depicts the preliminary Ground Gravity data, first vertical derivative of Bouguer gravity data shown, using a Colour table that shows gravity lows as being RED. No shading has been applied to the data in the generation of this image. The gravity lows of interest are circled. There are 14 new features of interest, some clustered together. The location of the gravity survey with respect to the wider tenement package is shown as the inset bottom right.
The Ellendale Project consists of exploration licence applications ELA 04/2832, ELA 04/2830, ELA 04/2834 and ELA 04/2833 which were applied for by Odessa. The applications surround the Ellendale Diamond Field and are located approximately 160 kilometres east of Derby and 100 kilometres west of Fitzroy Crossing, Western Australia.
The Ellendale Project is located in the Permian Fitzroy Trough, one of four sub-basins separated by basement highs that together comprise the Canning Basin. The basin comprises a sequence of continental sediments dominated by mudstones to cross-bedded fine sandstones with occasional coarser units. The Ellendale Project has been subjected to diamond exploration from the mid-1970s.
