Thanks @Babawale_Sodiq - I note a few things. You counted number of unique geologies, you used gradient multiplier to address unbalanced data (most others I saw used SMOTE or thresholds) and you had a few nice features! You used e.g. ranges and ratios to measure dispersion.

I am really intrigued with what made you able to do so well in this comp and really appreciate that you shared the whole solution! Thanks.

Thank you for sharing your solution. Really great approach. Just a question what feature selection technique did you use to select the features used in modelling?

I selected the top most features from each of the models' feature importance.

Congratulations @Babawale_Sodiq. Thanks for sharing the solution too. That was a great approach.
