The individual or group whose submission represents the best prospect for the next big gold discovery on the Sigma/Lamaque properties, based on a weighted set of criteria as outlined in the challenge rules, wins their share of the C$1 million prize.

More than 750 competitors from more than 60 countries, from Australia to Zambia, have pre-registered for the Gold Rush Challenge. Today, they will receive access to the data to begin their analysis. Registrants from academia, geology, mining, engineering, data science and many other non-geoscientific disciplines have already signed up to analyze 75 years of drill holes, gold assays, underground workings and photos from the Sigma/Lamaque properties. Interested parties can register now by visiting www.herox.com/integragoldrush.

The Challenge winners will be announced following a “Shark Tank” like charity event for the finalists on Sunday, March 6, 2015, during the Prospectors and Developers Association of Canada (“PDAC”) conference held in Toronto. Additional details will be posted on the Company’s website as they become available.

AWS will host and facilitate access to the Gold Rush Challenge’s data. Gold Rush Challenge participants will also have free access to software giant Leapfrog’s 3D geological modelling technology, and geoscience technical support and challenge submission management from engineering firm WSP via partnership agreements with Integra Gold.

“We’re excited to announce a partnership with a digital data giant like Amazon Web Services to provide its cloud sharing technology to Gold Rush Challenge competitors,” said Integra Gold Chairman, George Salamis. “The services AWS is providing will allow competitors around the world to rapidly and securely access the data that will be analyzed as part of this unprecedented competition.”

“Great technology is at the heart of HeroX incentive prize challenges and we are very pleased that AWS is helping to make the Gold Rush Challenge such an interesting competition,” said Christian Cotichini, CEO of HeroX.

The Society of Economic Geologists (“SEG”) is also joining the Gold Rush Challenge as Research Partner. The SEG serves 7,000+ members worldwide who are committed to advancing the science and the discovery of mineral resources through research, publications, courses, and field trips. The SEG and its network of experts will provide competitors with, among other things, invaluable, free access to its wealth of past research on the Abitibi area geology and, specifically the Sigma/Lamaque properties.

“The Gold Rush Challenge exponentially expands our reach and access to quality people and ideas through the use of ‘online prospectors’, all the while allowing our team to remain focused on advancing high potential deposits such as the Triangle Zone,” said Integra Gold CEO Stephen de Jong. “We expect cutting-edge, innovative ideas to come not just from people in the mining and exploration industry but from anyone interested in or skilled at analyzing big data.”
