The　Apuseni-Banat-Timok-Srednogorie　(ABTS)　metallogenic　belt　is　one　of　the　world’s　major　porphyry-skarn-epithermal　Cu-Au　metallogenic　belts,　which　is　located　in　the　western　part　of　the　Tethys　tectonic　belt.　The　mineralization　ages　of　deposits　in　the　belt　is　mainly　the　Later　Cretaceous.　The　Timok　metallogenic　zone　is　located　in　the　middle　part　of　the　ABTS　metallogenic　belt.　The　Zlatno　Brdo　(ZB)　Au　deposit　is　a　newly　discovered　deposit　in　the　Timok　district　in　the　recent　years.　By　the　end　of　2021,　more　than　100　drill　holes　have　been　implemented　in　the　ZB　deposit,　with　a　total　drill　core　length　of　more　than　40,　000　meters.　The　controlled　+　inferred　resources　are　30　tons　of　gold　and　95　tons　of　silver,　with　an　average　grade　of　1.11　g/t　and　3.43　g/t,　respectively.　The　ore-body　is　controlled　by　faults　and　occurs　as　veins　in　the　Later　Cretaceous　plagioclase　hornblende　andesite.　The　genesis　of　the　deposit　and　exploration　criteria　are　still　unclear.　In　this　paper,　altered　minerals　and　sulfides　assemblages　have　been　investigated.　The　chalcopyrite,　tetrahedrite　and　other　mineral　combinations　indicated　that　they　formed　at　an　intermediate　sulfide　state.　The　Fe-poor　sphalerites　(the　average　FeS　mole　ratio　is　5.8%,　n=11)　and　Mn-rich　carbonate　(the　average　content　of　MnO　is　2.68%,　n=46)　that　associated　with　Au　mineralization　are　representative　minerals　of　typical　intermediate　sulfidation　epithermal　deposits.　Native　Au　and　Au-tellurides　coexist　with　hydrothermal　barite.　Besides,　we　modeled　the　alteration　zone　and　ore　body　using　3D　modeling　software　(MinESoft),　and　found　that　the　ore-bearing　alteration　zone　pinched　out　to　the　southeast　and　extended　to　the　northwest.　Combined　with　regional　geology,　this　paper　identifies　the　ZB　Au　deposit　as　an　intermediate　sulfidation　epithermal　gold　deposit.　The　northwestern　part　of　the　ZB　deposit　has　great　prospecting　potential.　Hydrothermal　barite　might　be　used　as　mineral　marker　for　ore　prospecting.　In　addition,　many　Late　Cretaceous　skarn　Cu-Au　deposits　have　been　discovered　in　the　Gangdese　metallogenic　zone,　which　also　belongs　to　the　Tethys　tectonic　belt.　And　100–80　Ma　magmatic　rocks　are　widespread　in　the　Gangdese　metallogenic　zone.　It　is　proposed　that　there　is　a　potential　for　further　exploration　of　intermediate-sulfidation　epithermal　gold　deposits　in　the　Timok　and　Gangdese　metallogenic　zone.　©　2023　Science　Press.　All　rights　reserved.
