Year 3 Annual Technical Report for EL 27412 Rosewood 29 January 2012 to 28 January 2013

Abstract

EL 27412 lies 80km south-east of Kununurra WA, and encompasses a portion of the Rosewood Station. The tenement covers 2 small bullseye style magnetic anomalies adjacent to a regional NE trending fault. A literature review and magnetic interpretation confirmed the area is of interest and requires further follow up work. The third year exploration program concentrated on the magnetic anomaly area. A ground gravity survey was conducted over at least one of the anomalies, and toward the eastern edge of another. An isolated gravity 5mGal anomaly was discovered coincident with the NE magnetic anomaly. The source of the coincident gravity and magnetic anomaly remains a mystery. Potential scenarios include; significant magnetite accumulations in the Cambrian flood basalts, Proterozoic intrusives in the basement complex or alternatively Cambrian gabbroic intrusive sills at depth. Previous interpretation of the two anomalies gave a source depth of about 800m. Although previous explorers have tested these concepts, a Norilsk style deposit has not been discovered in the Kimberley region at all.
