Well olivine is one of the main constituents of kimberlite but it is a phenocryst not a xenocryst, and I cannot see anyone chasing olivines themselves as they have many other sources besides kimberlite. It is pyrope, pyroxene, low titanium ilmenite and chromite that identify kimberlite and they are the indicators that you should use in float, in general not olivine. You can use olivine to determine fugacity of the kimberlite in the iron oxide ratios therein, but to use it as a indicator for float tracing is dangerous.

Majors often let land go because they believe that the juniors have to come to them for second stage money anyway. The often as Kennecott did, do sampling for first rights of refusal which ties up the junior anyway and lets them outbid on any project. That is why I will not sign a first rights agreement.
