The Camel Hills Project (Lodestar 100%)

The Camel Hills project is located 170 kilometres northwest of Meekatharra and 60 kilometres south and east of Gascoyne Resources Limited’s Glenburgh gold deposits. The tenements cover an area of 924 square kilometres and 90 kilometres of strike over the Errabiddy Shear Zone. The Errabiddy Shear Zone is a major structure 5 to 20 kilometres wide, forming a series of back-thrusts emanating at depth from the Cardilya Fault, the tectonic boundary between the Archaean Narryer Terrane (Yilgarn) and the accreted Palaeoproterozoic Glenburgh Terrane to the north.

Re-worked craton margins act as a deep plumbing system, allowing long-lived, repeated transfer of fluids and heat from the upper mantle to the upper crust. These margins are a favourable location for the formation of world-class orebodies, for example the Tropicana gold deposit (7.9Moz. Au) located on the southeast margin of the Yilgarn Craton.

The Geological Survey of Western Australia (GSWA) has completed regional regolith sampling across the Glenburgh 1:250,000 geology sheet. Stream samples from the GSWA data identify a large (~18 kilometre long) gold anomaly, overlying the Errabiddy Shear Zone, in the Camel Hills area. The Glenburgh gold discovery of Helix Resources resulted from the follow up of values between 2ppb and 17.2ppb gold in stream sampling and provides context for anomalous values in stream sampling. The GSWA sampling reported a maximum 8ppb gold within the Camel Hills anomaly.

Lodestar identified the “Main Grid” (re-named Big Sky) area and an extensive, under-explored area of anomalous gold in stream sampling, south west of Big Sky, as priority exploration targets for systematic surface sampling and drill testing.

At Big Sky prospecting, RAB and RC drilling identified high-grade gold associated with quartz veining along a sheared contact. Initial RC drilling directly beneath the surface discovery reported high-grade gold at shallow depth:

  •  6m at 6.6g/t Au from 13m in LCC011 and
  • 6m at 20.3g/t Au from 21m in LCC012

In-fill RC drilling below these intersections and for 150m along strike from the discovery holes also reported anomalous gold and although not repeating the initial high-grade mineralisation, confirmed that the contact is an important regional gold target. 

The sheared contact between magnetic rocks of the Petter Calc-silicate unit and the Quartpot pelite can be traced for at least 6 kilometres southwest of Big Sky, where a number of historic drainage sample anomalies are located. These untested gold anomalies remain important targets for systematic sampling, with the aim of defining discrete targets for prospecting and drill testing.
