Adavale Resources Limited (ASX: ADD) has identified a total of 32 discrete gravity targets following the completion of its ground-based gravity survey programme in Tanzania.
All 32 gravity targets are interpreted to potentially reflect underlying mafic-ultramafic intrusions which are capable of hosting significant nickel sulphide mineralisation.
The targets sit within the Company’s 100% owned Kabanga Jirani Nickel Project and the farmed-in Luhuma Nickel Project (areas, both located within the regionally significant and highly prospective East African Nickel belt.
The completed gravity survey encompassed the collection of approximately 24,000 gravity readings covering the company’s southern licence portfolio comprising Kabanga NE, North, East, Kabanga West and the Luhuma farm-in tenements, a combined area in excess of 1,000 sq kms.
The combined strike length of the 32 identified gravity targets is approximately 55kms.
“The measure of the success of this gravity programme is quite simply a reflection of the large number of high-quality targets that have been generated,” Executive Director, David Riekie, said.
“Without the gravity survey technique these targets would have otherwise remained undiscovered. This is because the targets do not have a recognisable surface expression and mostly remain completely hidden under the 50+ metres of thick cover of highly weathered lithologies and soils that covers much of our ground holdings.
“We have always maintained that we are in the right prospective geological setting for new nickel sulphide discoveries.
“With the benefit of our historical regional scale EM and magnetic data, together with our more recent soil geochemical, drilling and gravity as well as the soon to be completed deep penetrating EM data we are now well armed to focus our next drill campaign in ways to maximise our chances of making new discoveries.
“We are now at this value catalyst point in the timeline. We look forward to providing regular updates on these important activities and outcomes over the coming weeks.
Pathfinder Strategy and Rationale
Selection of gravity targets is based on the company’s forward modelling of the theoretical gravity response that would have been generated by conducting a gravity survey across the maficultramafic intrusions hosting the 58 million tonnes Kabanga deposit.
This modelling, using public domain information, clearly demonstrates that these outcropping and near surface non-outcropping intrusions would have been expressed as gravity anomalies in excess of 1mGal and detectable by Adavale’s regional gravity survey.
