Lodestar Minerals (ASX: LSR) has advised that a VTEM airborne electromagnetic (EM) survey has commenced over an area of the Western Block tenements (E52/2403 and E52/2512) within the company’s Peak Hill–Doolgunna Project, located in the North Murchison goldfield, Western Australia.
The survey area is located north west of Sandfire Resource’s (ASX: SFR) DeGrussa Cu-Au deposit, on the margin of Narracoota Formation (host to the DeGrussa deposit) and is adjacent to the Jenkin Fault zone.
A second phase of VTEM is to be flown over Lodestar tenements adjacent to Sipa Resource’s (Sipa’s) Thaduna Copper Project, where a number of electrical conductors were recently identified by the VTEM method.
The Western Block VTEM survey is targeting a magnetic complex that is overlain by unresolved gold in soil anomalies and includes evidence of anomalous copper in a fault breccia.
The area is transected by a series of north west trending faults and lineaments (identified in aeromagnetic and Landsat imagery) that intersect the Jenkin Fault zone.
The second phase of the VTEM survey will include areas of E52/2456 and E52/2468 that abut the eastern side of Sipa’s Thaduna Copper Project, where recent VTEM surveys conducted by Sipa have identified a number of bedrock conductors, with some conductors appearing to continue into Lodestar’s tenements.
The company said the survey will include the historic McDonald Well prospects and reconnaissance lines of VTEM across the K42 magnetic feature (both located in E52/2456) and Little Well South prospect (located within E52/2468).
Managig Director Bill Claton said the Capricorn Orogen, in the region of Lodestar’s tenements, exhibits a range of styles of copper occurrences and deposits, suggestive of a regional copper mineralising event or events.
