LOREX (LORandite EXperiment) is a geochemical project addressing the solar proton–proton neutrino flux for
the period of 4.31(2) Ma from the reaction 205Tl + νe → 205Pb + e− with a very low threshold (52 keV) for
solar pp-neutrino capture. A decisive step for this purpose is to obtain the precise, background-corrected ratio
of 205Pb/205Tl in the mineral lorandite (TlAsS2) as geochemical detector occurring in the ore deposit of Allchar
in Macedonia. This study presents a report on the excavation of lorandite bearing ore from adit P-21 of the ore
body Crven Dol as well as on the separation of pure lorandite from the raw ore. A detailed mineralogical and
chemical investigation of the separated lorandite is performed with special regard to the question of its use as
detector for solar pp-neutrinos.
