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
Crossland has entered into a Joint Venture on EL 3297 at Kalabity with Platsearch NL and Eaglehawk Geological Consulting Pty Ltd, as advised in CUX release to NSX of 1 November 2006. Under the terms of the agreement, CUX can earn at least 60%, of the project through expenditure. More details are available in the "Media and News" page of this website. The Kalabity Project is located in South Australia, approximately 100 kilometres west of Broken Hill, and lies in a district of historic uranium/radium mining that contains a variety of known deposit styles. Outcropping davidite mineralisation similar that that mined at Radium Hill has been discovered in the area, and previous work within the Kalabity title has generated other promising targets, for uranium as well as other commodities. Crossland plans an aggressive follow-up of these targets.

Source of uranium
The granites of the Curnamona Craton provide a fertile source rock for uranium deposits. Some of the phases of the granitoids reach ore grades, such as at the KR4 prospect at Kalabity, where specimen values of up to 4.72% U3O8 have been reported. These could form economic mineral occurrences in their own right, as supplies tighten in the future.
Transport mechanism
There is evidence that uranium is mobilised into calcrete over the Davidite occurrences. There is evidence that these approach ore grades in places. This is a probably active transport mechanism that may assist exploration even if calcrete orebodies are not formed. It may help to locate mineralisation that has taken different transport routes for targets in, for example, IOCG or pegmatite-hosted deposit models.
Site for deposition
In current models the site for deposition may well be part of the source rock, as it is in a pegmatite-hosted model. There is clearly uranium mineralisation in the Kalabity project area, and Crossland will do its best to understand and optimise this. Follow up of the detailed airborne geophysical survey conducted by Crossland at Kalabity in 2007 identified the Tabita Prospect, and auger drilling ,followed by air core drilling and trenching has been completed at the prospect. There appears to be carnotite (uranium vanadate) mineralization present at shallow depths, but this is not a calcrete deposit. A detailed assessment of Tabita will be made in 2010.
