The Kalabity Project, located in South Australia, lies in a historic uranium and radium mining district and has been subject to extensive exploration in the past, primarily on the KR4 prospect. Australia's first uranium mine, Radium Hill, lies 50 kilometres to the south.
Crossland entered into a joint venture on Kalabity in late 2006 with Platsearch NL (“Platsearch”) and Eaglehawk Geological Consulting Pty Ltd. (“Eaglehawk”). Crossland can earn at least a 60% interest in Kalabity through the expenditure of Australian $500,000 over three years.
Uranium Exploration Activities
Exploration activities at Kalabity included the field follow-up of a detailed airborne radiometric and magnetic survey, which identified over a dozen new targets. An extensive geochemical survey revealed a substantial uranium geochemical anomaly. The anomaly, named Tabita, is located three and a half kilometres northwest of the previously defined KR4 target. 23 anomalous bedrock values of up to 140 ppm uranium, above an anomaly threshold of 32 ppm uranium, have been obtained from a zone that remains open in all directions after samples were taken on seven lines up to 500 metres apart. In addition, elevated values of cobalt, copper and nickel were obtained from rock float and may represent a new style of mineralization as its signature differs from other patterns in the area.
Selected samples collected during the previous quarter were analyzed for a broader range of elements, and this revealed an area with palladium (“Pd”) values up to 134 ppb on the KR4 grid. The Tabita results and the elevated Pd values were followed up with an auger drilling program in February to March 2008. Approximately 630 samples are currently awaiting analysis at the laboratory.
Results of the recently completed auger drilling program are awaited and these will determine the direction and amount of additional work.
Location
The Kalabity project is located in South Australia, 40 kilometres north of Olary and approximately 100 kilometres west of Broken Hill.
Property Size
The Kalabity project encompasses an area of approximately 148 square kilometres.
Principal Target
Targets at Kalabity include granite-related uranium deposits and iron oxide copper gold deposits.
Project History & Geology
Platsearch and Eaglehawk compiled the previous exploration data after applying for the property in 1999. The project lies within the Olary Uranium Field in the southwestern portion of the Curnamona Craton. This is a district of historic uranium and radium mining and contains a variety of known deposit types. Australia’s first uranium mine, Radium Hill, lies 50 kilometres to the south. The KR4 prospect within the Kalabity title was discovered in 1985 by prospecting, while the first uranium discoveries in the Olary Uranium Field were made at Radium Hill in 1906. The Field also includes Crocker Well, Mt. Victoria, Spring Hill, Jagged Rocks, Honeymoon and Gould’s Dam deposits, in the district surrounding Kalabity. Outcropping davidite mineralization, similar to ore mined at Radium Hill, has been discovered at the KR4 prospect in the Kalabity Exploration License and exploration has identified several targets in the license area.
The Kalabity area has been subject to extensive exploration in the past, targeting the KR4 prospect with granite-related davidite mineralization similar to the ore at Radium Hill, with values of up to 4.72% U3O8 from surface specimens. The KR4 target and Radium Hill share a number of similarities, including davidite mineralization associated with biotite gangue and a northeast strike direction.
In addition to uranium exploration, recent exploration has concentrated on iron oxide copper gold deposits of the East Mt. Isa and Olympic Dam style.
The Kalabity project area has moderate bedrock exposure although significant areas have thin, unconsolidated alluvial, colluvial and aeolian cover, usually much less than 20 metres in depth. Calcreted soils form a large portion of the cover.
