Report id: CR2007-0527
Tenure: EL22307
Year: 2007
Abstract: EL 22307 is considered prospective for commercial sources of diamonds. Historic sampling has identified kimberlitic indicator mineral occurrences, including diamonds within the tenement. A Falcon airborne gravity gradiometer survey was planned and flown in September 2003. The survey covered 217 km2 within EL 22307 and comprised a total of approximately 2500 line kilometres of effective survey coverage. The coverage within blocks relinquished during 2007 is limited to 8, one minute graticule blocks Limited work was completed within EL 22307 during year 4 of tenure, primarily due to weather and drilling contractor availability issues. Sampling within the relinquished blocks was carried out during the Year 5 tenure, with two gravel samples collected and processed from within the relinquished blocks. This sampling was carried out as a part of a larger campaign focused on EL 22307. Both gravel samples failed to contain kimberlitic indicator minerals. A relinquishment of eighteen (18) blocks was made at the conclusion of Year 5 of EL 22307. An application for a partial waiver for twenty (20) blocks was approved by the Department, leaving a retained area of fifty-eight (58) blocks in tenement EL 22307.
