Year 6 annual and final report on exloration activities for EL 22732 Mt Young

Abstract

EL 22732 'Mt Young' was acquired by Gravity Capital Limited from BHP Billiton soon after it was granted, as part of a diamond exploration venture involving Gravity, Gravity's 100%- owned subsidiary, Diamond Mines Australia Pty Ltd and BHP Billiton. Gravity and Diamond Mines Australia also have a diamond exploration arrangement with Rio Tinto Exploration covering a large number of Rio Tinto-controlled tenements in the Northern Territory. During the second year of tenure, on the basis of encouraging diamond sampling data from nearby tenements, a Falcon airborne gravity gradiometer survey was flown over a substantial part of the Mt Young tenement. Detailed interpretation, anomaly ranking and exploration targeting from the Falcon data by Gravity Capital was completed during 2004. Gravity Capital Ltd changed its name to Gravity Diamonds Ltd late in 2004 to reflect its sole emphasis on diamond exploration and development. Several potential target areas were identified from the Falcon survey as requiring ground follow-up work. Statutory requirements for field access and approvals for work programs were finalised in early 2005 and field testing of these targets was carried out during the 2005 and 2006 field seasons. During Year 5 of the licence, further helicopter-supported field reconnaissance and sampling programs were conducted in the district and within EL 22732. Results from this sampling were moderately encouraging with most samples taken returning at least a single chromite. During Year 6 of the licence a review of the data available on the licence highlighted that no major kimberlite targets had been identified from the gravel sampling data, a new Falcon(r) survey was contemplated, as being the best tool available for generating kimberlite-type targets, however the level of chromite anomalism in this tenement did not warrant a further survey. EL 22732 was surrendered on 5 September 2008.
