Allchar is one of the oldest mines in the Republic of North Macedonia, situated in the southern part of the country. Some legend suggests that mine was in use from ancient - antic time, but other information estimates its use since 12th or 13th century. Exploitation was focused on arsenic-antimony ore.
From 47 worldwide registered minerals containing thallium (Tl), 13 exists in Allchar. Thallium is extremely interesting for the science as a geochemical detector of solar proton-proton neutrinos. Allchar is known as a unique mine in the world, richest of purest (contains only traces of K, Cr, Fe, Cu, Pb and Zn) deposits of lorandite (TlAsS2), the most common mineral containing thallium.
Aim of this study was detection of presence of microbes and microbial diversity (bacteria and fungi) using metagenomic methods and bioinformatic analysis.
Six samples from three different areas of the mine were investigated. DNA was extracted with special kit for environmental samples.
Results, presented through the Krona viewer, showed presence of huge microbial community. On phylum level most dominant in all samples were Proteobacteria (36-43%).
In two samples, results for fungi showed presence of fila Ascomycota and Zygomycota.
ICP-OES analysis prepared according EPA method 3051a, detected 25 elements and high concentration of As and Tl.

Keywords: Allchar, diversity, microbes, mine, minerals, lorandite, thallium.
