How to Unfold or flatten SEDEX deposit model

Kazbek 5 years ago in Resource Estimation 0
Dear colleagues, 

Need your help!
I'm in the process of resource estimation of SEDEX deposit.
Flattening process is getting not correct result, below on the section view you can see the result where green is initial model and yellow is flattened one:

Unfolding by central DTM also gives not perfect result, below the pink one is unfolded model:

For the preliminary estimation I wanted to use unfolded model but Kriging gives an error: "Unable to calculate parent block size for this model".

Please suggest how to correctly unfold or flatten such model?
