PEAKE-DENISON PROJECT – GRAWLER CRATON- SOUTH AUSTRALIA
(Cooper, Gold, Iron)
Falcon has a large land position in the Peake-Denison Inlier of the northern Gawler Craton that it considers prospective for iron oxide-copper-gold systems.
The Peake-Denison Inlier represents a major uplifted Proterozoic basement block with discrete gravity-magnetic anomalies associated with major basement fault intersections. This geological and structural setting shows many similarities to the Olympic Dam and Prominent Hill districts.
Detailed 3D geophysical modeling has defined two significant anomalies at Spring Hill and Davenport Creek. These targets comprise elongate to pipe-like bodies with geophysical responses that are consistent with known large iron-oxide-copper-gold systems.
Limited previous drilling by other explorers near these targets has detected widespread copper anomalism (> 0.1% Cu). It is apparent from the 3D modeling that the historic drilling failed to test the core of the gravity targets.
The best historical drill hole intersection was at Davenport Creek where DCDH01 reported 3m at 2.75% Cu from 330m associated with magnetite-hematite-chalcopyrite breccias in basement rocks. A further 14m of anomalous copper (av. 670 ppm Cu) was intersected in altered pegmatite from 390m to the end of the hole. A down-hole EM survey was completed on this hole and indicated an off-hole conductor.
Falcon is currently preparing an Exploration Work Approval and Environmental Management Plan for future exploration activities including drilling the Spring Hill and Davenport Creek targets.
