Presently, there are three recognized ore zones in the deposit, with the most significant occurring over an area 140?m in length and 12?m-wide, with typical grades of 7 to 9?g/t Au. Brecciated veins in the 18?t Au Lukhra deposit cut a small granodioritic to dioritic stock the latter intrudes Devonian schist immediately north of the thrust. Lode gold potential was first recognized in the historic placer district in the 1980s, with many auriferous quartz veins cutting Middle Jurassic igneous rocks. More than 60 gold-bearing lodes and placers in the Svaneti district occur along the thrust between the Southern Slope and Main Zones. ?34S values of + 1 to + 4? for ore-related sulfides at Zopkhito are consistent with a sedimentary rock source for the sulfur, and ?18O quartz measurements of 16 to 21? are consistent with either a magmatic or metamorphic fluid. Ore-forming fluids, with approximately 5 to 20?mol% non-aqueous gas, evolved from N2-dominant to CO2-dominant during evolution of the hydrothermal system. Fluid-inclusion studies of ore samples from the Zopkhito deposit indicate minimum trapping temperatures of 300 to 350?C and 200 to 300?C for the two stages, respectively, and minimum trapping pressures of 0.2 to 0.5?kbar. A pyrite-arsenopyrite ore stage includes gold concentrated in both sulfide phases it is overprinted by a later stibnite-dominant stage. ![]() The veins are localized in an area where smaller-order structures show a major change in strike from N-S to more E-W trends. The Zopkhito deposit, previously mined for antimony, contains an estimated 55?t Au at a cutoff grade of 0.5?g/t. Gold deposition thus correlates with final collision of the Arabian plate to the south and uplift of the ore-hosting Greater Caucasus. Many veins in the district continue along strike for > 1?km and some cut Neogene intrusions, constraining ore formation to the most recent 4 to 5?million years. The veins occur in the footwall of a thrust fault between the Southern Slope zone and an earlier accreted terrane, the Main Zone, to the north. Quartz veins in the Mestia-Racha district were mined in Soviet times for As, Sb, and W, but many of these are now being recognized as gold resource targets. Quartz veins in the more carbonaceous slate units are most consistently enriched in As, Au, Hg, Sb, and W, and show mineralization styles most consistent with typical orogenic gold deposits. The slates were subsequently intruded by both Middle to Late Jurassic and Neogene granitoids. This metalliferous region is dominated by Early to Middle Jurassic slates, which are part of a terrane that likely accreted to the continental margin from late Paleozoic to Jurassic. ![]() Gold-bearing quartz veins are concentrated in two extensive WNW-trending belts, the Mestia-Racha and Svaneti districts, within the northern margin of the Southern Slope Zone of the Great Caucasus orogen. So many awesome features with this home: 3 bedrooms, 2 full bathrooms, over 1500 square feet, beautiful pine hardwood floors throughout, large master suite with two separate closets, separate dining room, wood burning stove for those cozy winter evenings, large rocking chair covered front porch that could easily be screened in, beautiful easy maintenance mature landscaping (hydrangeas, peach trees, pear trees, blueberry bushes, etc.The south-central part of the Greater Caucasus region, Georgia Republic, represents an extremely prospective region for significant orogenic gold deposits.
