For block kriging yes, for point kriging the prediction (standard) error
will be close to sigma.
And happy new year to everyone on ai-geostats!

If you use a semi-variogram which is just nugget, the kriging estimate will
be the arithmetic mean of the sample values and the standard error will be the
standard sigma/root n of classical statistics.

Dear Mehari Tekeste,
Kriging with a pure nugget model is about the same as predicting everywhere
with the mean of the observations, which is probably the best you can do if
there is no spatial correlation and no further information. The kriging error
i.e. the prediction variance will be (1+1/n)C_0
