Hi GeoGeorge,

Seems like u are quite knowledgeable in this area....In response to your above post on depth to top of deposit what do you make of this from company ann / research comparing Mt Barrett and Mt Weld ?

"The 3D model for Mt Weld indicates depths to top that range from ~200‐600 m below surface and the Mt Barrett 3D model indicates depths to top between ~300 m and 500 m. These indications are somewhat subjective as they depend on the magnetic susceptibility chosen to define the tops of the features. However, both models show the bulk of the magnetic components of each feature are ≥ 250 m and show variable depths to top. For both models, the depth to top/diameter ratio is less than ~1/3. This ratio is favourable for constraining both the diameter and depth to top in the modelling process."

Im certainly no expert but have some skin in the game and interested in your view.
