Summer Placement 2016 Cardiff University - Week 2, Rudnik

Moving into our second week in Rudnik, we set out into the field with the main focus to locate old pinga and adit workings, excavated during Roman, medieval and more recent times. As we recorded geological observations and structural measurements of these features in our notebooks, it became clear to us that the Roman and medieval miners were extremely smart, as nearly every single one of these...

Summer placement 2016 Cardiff University- Week 1, Getting to Know Everyone.

Hello, my name is Alice O’Neill and I am here from Cardiff University along with Jack Welch. We are both studying Exploration and Resource Geology and are about to embark on our final year, but first, our 6 week placement with Mineco. We arrived in Belgrade on the 29th of June and were met at the airport from which we were taken to Rudnik. Here we were made to feel very welcome and not only... Read more

MSc Dissertation - Week 6 - Mining, Processing & Geochemistry

With the samples in the bags, photographed and weighed – I prepared them for the geochemical assay in the on-site laboratory of Rudnik mine. Upon my visit to the laboratory and I was presented the with the process of sample preparation and analysis by Ljiljana, the laboratory manager. This was particularly interesting to me as I was involved with sample preparation, geochemical analysis and... Read more

MSc Dissertation - Week 5 - Channel Sampling

With the preparations of the last weeks completed and everything in place for my sampling campaign, I set out to take channel samples over almost 200m of strike length across the vein mineralisation. This was to test the grade and thickness continuity of the mineralisation and to correlate it with the structural measurements that I collected last week. Due to the available exposure in the...

MSc Dissertation Placement - Week 4 - Structural Mapping in the Rudnik Deposit

The fourth week was mainly about structural mapping in different areas of the project, the identification of structural features, the measurement of their orientation and analysis of the association with mineralisation. The survey of the structural aspects of the mineralisation is especially important when dealing with hydrothermal vein deposits. This is because hydrothermal vein mineralisation... Read more

MSc Dissertation Placement - Week 3 - To Sample or not to Sample

The third week at Rudnik began late after my return from a great weekend in Belgrade. We began with an investigation for unexplored vein mineralisation in a distant area of the exploration license. Stream sediment sampling is a common technique for greenfields exploration, as it is a fast and inexpensive method which can direct further exploration efforts. Ideally a sediment sample is taken and... Read more

MSc Dissertation Placement – Week 2 – Developing a work plan

The second week started with a field trip to the Srednji Sturač mountain (meaning middle Sturač) to investigate sites of historic mining (so called ‘pinges’). The survey of these former mining sites is a common approach for exploration, but they are also important for underground development, as voids from old adits could pose geotechnical risks. The historic mining at Rudnik has been ongoing... Read more

MSc Dissertation Placement - Week 1 - Getting to grips with the geology.

My name is Richard Roethe, I am a German student of the Camborne School of Mines in the UK. As part of my MSc-degree in Mining Geology, I have to produce a dissertation that is associated with geological issues which are commonly encountered in the mining industry. Regarding the economical state of the industry at the moment, I count myself very lucky to have been given a ‘hands-on’ opportunity... Read more

Practical Exploration Geology IV - Digitisation of Historic Data

The Balkans are a heavily mineralised region with a long history of mining stretching back to Roman mines of the second and third century. Industrial mining starting with the Austrians in the mid-nineteenth century and a number of British companies, including Selection Trust were present up until the outbreak of the Second World War. Prior to the break-up of Yugoslavia a lot of mines and... Read more

Practical Exploration Geology III - Adit Re-opening

In July Mineco’s PDT started the exploration programme on the newly acquired Rajkovici-Seliste-Celebici (“RSC”) exploration concession located in South East Bosnia adjacent to the operating Supla Stijena mine across the border in Montenegro. Whilst the area had been subject to relatively extensive exploration, both during Yugolsav times and much earlier, there is very limited historical reference... Read more
