Forget geostatistics, you don't have enough data. What will you do with the results? Do you need the information only at the surface or the whole depth of the borehole? Do you need to model the spatial distribution of the properties or is a site-wide average sufficient?
The most sophisticated statistical procedure won't improve on limited data. With four data points, I would stick with averaging or hand contouring.
