The objective is to dig beneath the church, starting with the apse underneath which there is a strong possibility of finding a crypt (cavities detected by the Eisenman and Heygate GPR soundings in 2003 and 2008 respectively), then proceed westward underneath the nave, where, again, there is a strong possibility of finding the seigneurial burial vault, which is known to exist according to the 1694-1724 parish register found by Corbu & Captier in Saunière's papers, and -according to my sources- which has been detected by the Heygate investigations in 2008.

In order to proceed with minimal damage to the existing structures, Saunière's "secret room" (built in 1891/1892) will have to be dismantled then rebuilt after the dig; another possibility, with no dismantling/rebuilding, is to dig from the cemetery, provided there are no obstructing graves.
Whatever is found will have to be "stabilised", i.e. temporarily stored in a safe place nearby for cleaning, etc., and a decision will have to be made whether the material will be put back in place or prepared for exhibition in a museum or a similar facility.

A more delicate issue is how to handle and what to do with the human remains which will most certainly be found.
It is also anticipated that various artefacts such as engraved tombstones, items of clothing, personal jewelry, weapons, etc. will also be found.

One of my first asks will of course be to find a suitable archaeologist: I have a particular one in mind, but it's far too early to speculate.

Another hefty task will be to secure financing for the operation: I will have to approach various private foundations.

DRAC will of course come into the picture, but at a later stage.
