Yet he was (and still is) the only student of the university that wrote a diploma thesis on precious metals as a protection against inflation (“Gold in a Macroeconomic Context with Special Consideration of the Price Formation Process”) that was completed in 2002 under the supervision of Professor Bocker. Mr Bogner specialized in Finance & Asset Management, Production & Logistics and International Law & Entrepreneurship.

In 2003, he started working closely with Ferdinand Lips, among others to publish and market his latest bestseller (“Gold Wars – The Battle Against Sound Money As Seen From A Swiss Perspective“) in the German-speaking countries. Bogner revised and translated the English version into German (“Die Gold Verschwörung”). In 2004, he went to work at the biggest gold market in the world (Dubai), where he started up two companies specialized in re-selling and brokering physical commodities as well as consulting services for publicly listed mining companies. Bogner was co-founder and, until late 2006, partner of the first German silver stockletter and online information platform (silberinfo.com) besides dealing with coins and bars. Since 2003, Bogner is specialized on the analysis and valuation of capital markets and publicly listed companies with a focus on geology, exploration, development and production of resource deposits. Since years, he lives in Zurich (Switzerland) and regularly publishes articles in German and English about economic contexts, currencies, commodities and companies active in exploration and mining of natural resources worldwide. Besides his activities as an analyst, Bogner is CEO of Swiss based Elementum International AG specialized in the duty-free storage of bullion at a high security vaulting facility within the St. Gotthard Mountain Massif in central Switzerland.

John P. Barry
Managing Director of Irus Consulting Ltd. and Professional Geologist

A widely travelled and highly experienced economic geologist, John Barry is a confidential counsellor to the likely investor contemplating a considerable investment in the intricate business of mining metals. DonÂ’t take a “flyer” and trust altogether in luck and invest your money in an exploration or mining project on the strength of a printed prospectus or the advice of an interested friend without the preliminary investigation and site visit of a reliable geologist with a basic grasp of commerical reality.  Irus Consulting provides  strategic and practical management advice and guidance  to its clients.  Time is a precious commodity for my clients, and indeed myself, as it relentlessly ebbs away and so I  try as best I can to avoid the mediocre - those projects and their champions which do not engender enthusiastic belief and passion.

Irus services include:
- High-level strategic advice
- Practical guidance and assistance on project sourcing, acquisition and implementation
- Rapid identification of key project value-drivers and potential fatal flaws.
- Capacity building and coordination of  external consultants.
- Design and targeting of effective marketing campaigns

John Barry was part of very small teams which discovered and sourced several multi-million ounce gold deposits in Africa. He has worked as an economic geologist since 1988 and as a consultant and then responding to the entrepreneurial spirit he was a founder and manager of three public resource companies which raised a total of US$70million. These resource companies are currently successfully exploring and developing gold and base metal projects in Europe, and sub-Sahara Africa. John has seen a lot of rocks working for consultancies such as CSA in both Ireland and Australia and as Senior Associate Geologist with Chlumsky Armbrust & Meyer LLC which is based in Denver.  He is a specialist in zin-lead exploration and in 1992 joined the exploration team which discovered the Lisheen zinc-lead deposit in Ireland as the resource was being expanded in the first couple of years after discovery and in 2008 led the first non Polish exploration company to successfully enter and acquire a major resource-project in the Upper Silesian Mississippi-Valley-Type (MVT) zinc-lead district  in southern Poland – the worldÂ’s largest minerlised district of its kind. John (P.Geo and EurGeol) holds a MasterÂ’s Degree in Geology from Pennsylvania State University and a MBA from the Edinburgh School of Business, Heriot-Watt University, Scotland.

"“I would like to think that I have shown the tenacity, patience and focus required to implement many of my better ideas over the years and that I have learned valuable lessons from some failures. I believe one of my strengths is in communicating quite complex technical ideas in a concrete way that can be easily understood. I am a team- builder and motivator by projecting my enthusiasm and vision for a project. I am committed to the development of young geologists through supportive delegation.”" 

John is now moving more from managing public companies to freelance consultancy and a more advisory role so as to concentrate increasingly on assisting management in effective exploration and discovery. He is Managing Director of his own Exploration Management and Geological Consultancy: Irus Consulting Ltd.
