Curara Well


Copper (± Gold)
OAU 90%

The Curara Well Project is an Exploration Licence E52/2402 located in the Doolgunna region of Western Australia immediately north and east along strike from Sandfire Resources NL’s tenure and its operating DeGrussa copper-gold mine. The tenement covers 83 square kilometres encompassing approximately 15 kilometres in strike length of the Jenkins Fault Zone, a major crustal feature that is considered to be a significant influence on the origins and emplacement of the DeGrussa mineralisation.

Ora Gold Limited currently holds a 90% interest in the project. The balance is held by prospector Mr Bill Richmond, who received his 10% stake (which is free carried to a decision to mine) as part of the March 2014 settlement negotiations in which Ora Gold moved from 60% to 90% interest in Red Bore.

Soil sampling, geophysical surveys, geological mapping and drill programs over the past few years have tested a number of targets exhibiting apparent associations with the Jenkins Fault zone.

Drilling in 2013 identified anomalous copper values with sulphides present at several targets, without encountering any zones of potentially economic metal concentrations. The drilling did, however, identify a target that potentially could represent a hydrothermal feeder vent. This target is yet to be tested and will require Heritage Clearance Surveys to be completed before any testwork can be undertaken.

Exploration to date at Curara Well has focused on the zones around the interpreted position of the Jenkins Fault. The western part of the tenement has generally been ignored in the past due to the extensive presence of granite mapped at surface and thus considered of limited prospectivity. A new model recently postulated by Ora Gold’s Chief Geologist offered an interpretation that the granite at surface may possibly be thin cover of granite sheets over prospective sediments and volcaniclastics of the Narracoota formation below. This theory, that the granites were fractured and thrust over the top of the sediments in a continental collision event, is yet to be tested. In support of the theory is the fact that this is the exact geological setting 20 kilometres or so to the north where the Plutonic gold mine and surrounding satellites (which have produced in excess of six million ounces of gold) are hosted by Archaean greenstones that are partially concealed beneath over-thrust sheets of granite.

Ora Gold Limited plans to conduct seismic profiling over the granites and across the Jenkins Fault Zone and the contact with the prospective Narracoota formation to the south. This will hopefully establish whether or not the theory is valid and if so, will assist in identifying targets for drill testing beneath the granite cover.
