For the first seven days, at the Olovo mine, active and historic underground workings were visited daily, allowing the external participants to get a good overview of the different geological properties of the ore zones and the host rock across different levels. Following this, for several days, the observed mineralisation styles were documented at the 580 level through detailed mapping, photography and sampling. We concentrated on methods to capture the close spaced variability that is commonly associated with narrow vein complex deposits.
Towards the end of the trip, a visit to the MINECO database geologist, Mr. Milan Milasinovic gave a significant insight to the commonly encountered resource estimation issues on deposit with complex geology and low data. On the final day, the team visited historic workings of Austro Hungarian (1720s) and Roman origin at Mineco’s Rudnik Mine in Serbia. This will feed into action point 2 of Task 2.2, investigating the issues of historic and ancient mining, and what practices could be relevant to this project (if any). We also were able to visit a recently open narrow vein, which is being mined in a shrinkage stoping method at the Rudnik Mine.
