Location and Background

  • The Kyarra Cobalt Project is located in the Yerrida Basin, WA and is considered highly prospective for structural/stratigraphic-controlled copper-cobalt and potentially nickel mineralisation. Based on a geological evaluation of the region the Company has developed an exploration model that includes numerous aspects of significant copper-cobalt (+/- nickel) deposits of the Central African Copperbelt, where new discoveries continue to be made based on advances in exploration concepts.
  • Within the Kyarra Cobalt project area anomalous historical results have been reported including up to 0.64% Co from surface samples and 2m at 612 ppm Co from drilling, across an initial strike extent of approximately 25km.  
  • Three granted exploration licenses covering 643 km2 provide a dominant land holding in the district.
  • The Yerrida Basin is an emerging cobalt district where the Company commands a significant landholding of tenements strategically located in a prospective geological setting. The widespread cobalt anomalism identified over an initial 25km strike extent at Kyarra West represents a compelling target area for further study and drilling.



Regional Geology

  • Yerrida Group rocks are flat-lying to shallowly dipping and unconformably overly Archaean granite greenstones to the south, including the N-S trending Joyner’s Find Greenstone belt immediately to the east of the tenements; where various steeply dipping greenstone lithologies including mafic volcanics, BIFs and other sediments host a number of Fe and Au prospects
  • The Yerrida Group comprises an early sag-basin succession dominated by siliciclastic and evaporitic sediments deposited in a shallow-water environment, overlain by arenaceous, argillaceous and mafic volcanic rocks.  
  • The units of interest within the Project area are carbonaceous and calcareous, pyritic shales and siltstones of the Maraloou Formation. Zones of limestone breccia and stromatolitic limestone are present at the base of this unit, in mineralised zones observed in diamond core.



  • The Yerrida Basin sedimentary package also contains a number of the key elements necessary for SEDEX style base metal mineralisation, including evaporites, siliciclastics, hydrocarbons and basin bounding faults.
  • Extensive exploration activities were completed in the late 1980’s and 1990’s focussed on discovery of base metal deposits using this model. 
  • Within the area that includes the Kyarra Cobalt Project approximately 2000 surface geochemistry samples, 770 RAB holes (0-96m deep), 116 RC holes (4-250m deep) and 9 diamond drill holes (75-405m deep) were completed by various operators including Renison Goldfields Consolidated (RGC).
  • Anomalous Cu, Zn, Pb, Ni and Co detected in surface geochemistry and drilling culminated in the discovery of the Magellan (now Paroo Station) Lead deposit 12km east of E53/1894. 
  • The company has developed a new exploration model targeting sedimentary hosted copper-cobalt-nickel deposits similar ot those discovered in the Central Africal Copperbelt.

Successful results

  • The Company is currently undertaking surface exploration with successful results in the Kyarra West area.
  • The most recent rock chip sampling results show results of up to 1,500ppm C and >1% Zn in weathered near-surface area.
  • The current theory, suggest that this anomalism has been observed to be associated with west-north-west striking breccia zones interpreted to be related to deep-seated structures and to represent part of a plumbing system for metalliferous fluids upward and southward into suitable trap horizons.
