HARDROCK SUMMIT – A COMMON GOALThe HardRock Summit 2022 in Denver is organized by a team of specialists led and driven by the two founders Christoph Keilmann from Munich and Wolter Mehring from Los Angeles.
Christoph Keilmann is the manager and organizer ofGemworld Munich, the largest trade show in Europe that brings together natural treasures, jewelry and gemstones under one roof.
Wolter Mehring is an international businessman with in-depth knowledge and experience in the U.S. market, including the development of the Pueblo Gem & Mineral Show in Tucson, AZ.
Looking back on 15 years of friendship and international business projects, their strong visions, knowledge and ideas have created this year’s very special and ambitious project.Their goal is to break down barriers once and for all and achieve a common goal: Everyone who attends or exhibits at the Hardrock Summit will feel, share and benefit from their passion and vision. ​


​For the second time, the two critical elements of tradition, vision, commerce and community are successfully brought together to achieve the combination of “knowledge and legacy.
“Back in the 1960s, Christoph’s parents, Johannes and Hermi Keilmann, were pioneers and the driving force behind an emerging market.
Johannes became a sought-after mineral specialist and created the first trading platforms over the years.
As a trained engineer, he was driven by his passion and perfectionism.
All of his colleagues had science or geology backgrounds and shared the same love – but none of them had specialized marketing or event knowledge.
Nonetheless, each did what they thought was good, and that’s still the case: you can hire great event companies to organize an event, but they don’t share your passion.
Or people with the same passion can try to organize their own professional events, but lack marketing or event management expertise.So for 2021, a new standard has been set. With knowledge and legacy – and with the power and passion of a great team, HardRock Summit will unite all people into one community and provide an unprecedented high-profile platform for all interests and needs, trade, exhibition, commerce and education. We are now looking forward to 2022! ​


The big gap between B2B and B2C needed to be closed. Over the years, of course, clear and distinct parameters disappeared, but the habit of these divisions and social affiliations remained and remain.There are at least two major interest groups – professionals who make a living selling products and services, and non-professionals who engage for pleasure. These two groups tend to hold their own events, trade shows and meetings, and often subdivide even further to target only a particular segment of the trade or material. And then, of course, there is the further subdivision into minerals, fossils and stones – and – at the other end of the scale – the jewelry and gemstone market. Until now, most events have been created for, and attended by, only one of these groups. 


The HardRock Summit brings markets, exhibitors and attendees together, creating unprecedented benefits for all by bringing the entire community together in one place: Information. Trade. Exchange. Learning. Business. Fun; it’s all there!.That’s it in a nutshell! Everyone, whether an attendee, exhibitor or tradesperson, will have benefited from their participation in the 2021 HardRock Summit in Denver. Everyone felt a sense of belonging. The message was understood. And now we are preparing for 2022 to be even bigger, even better.


Denver was chosen as the location for the HardRock Summit for good reason: It’s a beautiful city with history and tradition – naturally grown as a location at the base of the Rocky Mountains, one mile above sea level. For decades, miners, geologists, scientists and mineralogists have worked and traded here. Unfortunately, their business has grown somewhat stale over time, and its continued existence is not assured. . But with a sophisticated structure, a holistic approach, and by linking the two main areas and their communities, a lively, vibrant marketplace has now been created for all to enjoy. 

With its long history and mining tradition and the power to grow and flourish under modern aspects, Denver is predestined for the HardRock Summit and easily accessible due to its large airport hub and integrated infrastructure.

Together with their ambassadors, Christoph and Wolter are in the process of putting together a strong and comprehensive program with plenty of highlights, information and even a surprise or two – while leaving space and time for attendees to make their own plans and connect with other community members.

Business management knowledge, experience and industry knowledge within the entire production and supply chain are the basis for the organization of a market-relevant trading platform. The building on this consists of dynamic processes. Always creative, always inspiring, but also with passion and willingness to take risks. Only then does success set in.

“The HardRock Summit will be the central meeting point for all those who see themselves as part of our community and those who want to be. Besides our ambition to build a high quality market platform, our focus will be on emerging trends, first-hand news from the industry and the joy of sharing experiences and visions.”

As a business metropolis in the center of the USA, Denver, with its traditional mining history and fantastic infrastructure, is the ideal location for our Summit.
