12. The method of claim 2 , further comprising supplying Helium gas to the XRF detection subassembly.
13. The method of claim 2 , further comprising:
receiving, from a first wireless transmitter-receiver communicatively coupled to the at least one processor, by a second wireless transmitter-receiver communicatively coupled to a database, information indicative of the measured XRF of the chips positioned within the sample analysis area.
14. The method of claim 13 , further comprising:
transmitting, from the second wireless transmitter-receiver, information from the database to the first wireless transmitter-receiver.
15. The method of claim 13 , wherein the database is a centralized database that includes respective data sets acquired from a plurality of analysis assemblies that acquire XRF data.
16. The method of claim 2 , wherein the analysis assembly is positioned at a site of the reverse drilling operations.
17. The method of claim 1 , further comprising loading the core tray onto a sample loading location of a sample movement pathway.
18. The method of claim 17 , wherein receiving the core tray within the sample analysis area comprises advancing the core tray from the sample loading location to the sample analysis area.
19. The method of claim 18 , further comprising, following delivery of radiation to the chips within the core tray, advancing the core tray from the sample analysis area to a sample unloading location of the sample movement pathway.
