CUNaEAnRaTHdED a TDhe EOrNiginVal ER GEM & MINERAL SHOW SEPT 13 –15, 2019 • DENVER MART CUNaEAnRaTHdED a Laid bare between the Arctic Circle and vast prairies of the heartland, between the rugged mountains of the Cordillera to the stark cliffs of Nova Scotia, Canada’s rocks record four billion years of the Earth’s history. The world’s oldest known rock formations — the Acasta Gneiss and the Nuvvuagittuq Greenstone — are preserved in Canada’s cratons. These old crustal blocks, tortured by geologic processes over many hundreds of millions of years, are the source of much of the country’s enormous deposits of gold, nickel, copper, iron, zinc, and diamonds. An astounding 20 million carats of “ice” were recovered in 2018 from mines in the Northwest Territories. The ancient rocks were sculpted by tremendous impacts made by meteorites that slammed into Canada as the country was assuming its modern shape. The most famous of these impact craters is the Sudbury Basin, a 60-kilometer-long, 15-kilometer-deep hole that was produced 1.8 billion years ago. That crater has since filled with rocks that eroded over the last billion years. Today, Sudbury is one of Canada’s major mining districts and is famous for nickel and platinum minerals. Scientists theorize that the massive impact initiated melting of crustal and mantle rocks which then deposited these riches. Canada’s rocks also record the rise of life on Earth. High along a ridge in the mountains of British Columbia is perhaps the most famous fossil locality in the world. A modest outcrop of black shale of Cambrian Age (~500 million years ago), the Burgess Shale is an extraordinary cemetery filled with fossils documenting the sudden appearance of complex, multicellular life on our planet. Hundreds of thousands of fossils, including trilobites, have been “mined” from the Burgess Shale since the early part of the twentieth century. These memorials of past epochs provide a breathtaking glimpse of the evolution of modern species. The spectacular minerals, fossils, and meteorites that are on display in the 2019 Denver Gem & Mineral Show represent Canada’s natural history jewels. Perhaps more than that of any other country, Canada’s “bling” tells a compelling story of the history of our planet.

Jeffrey Scovil Photographer, Scovil Photography Speaker: Album of Canadian Minerals For nearly three decades, Jeff Scovil has been a full-time photographer of minerals, gems, jewelry, and other objects. Since the 1990s and after publishing his 1996 book Photographing Minerals, Fossils and Lapidary Materials , Jeff was the acknowledged world-leader in the highly specialized market of mineral photography. His exceptional work has been published in numerous books on mineralogy, geology, chemistry, and physics and can be seen regularly in most of the mineral magazines in the United States and Europe. His photos have also been featured on posters for shows in Tucson, Denver, Germany, France, and even Pakistan. Beyond being extensively published, Jeff’s photographic prowess has earned him unprecedented access to specimens and collections that most of us will never have the chance to see. He travels the world photographing for dealers and collectors of every ilk. His museum clients include the Mineralogical & Geological Museum at Harvard University, Arizona Sonora Desert Museum, Colorado School of Mines Geology Museum, Canadian Museum of Nature , Cranbrook Institute of Science , New Mexico Bureau of Geology, Fersman Mineralogical Museum (Moscow), Smithsonian Institution … the list is endless. In short, Jeff Scovil has seen it all; so when the 2007 winner of the Carnegie Mineralogical Award gives a presentation on minerals from Canada (or any locality in the world), his audience is sure to be surprised at what these wonderful localities have produced. Buckle up for a photographic tour of the very best of Canada from some of the greatest collections on earth. Cubanite, 2.1 cm tall. Henderson # 2 Mine, Chibougamou, Quebec, Canada.

Rod Tyson Geologist • Dealer • Prospector • Adventurer Exhibitor & Speaker Yukon Phosphate Minerals In the mineral community Rod Tyson’s name is synonymous with outrageous prospecting/collecting trips to the most remote parts of Canada, especially the northern Yukon. Since 1975, he has made 20 trips to the territory to collect minerals. That means being flown into the literal middle of nowhere and left with gear and enough supplies to last until the helicopter returns to take him back. Weather permitting. Wildlife encounters, erratic weather, and all kinds of challenges, expected and unexpected, are part and parcel of making camp and prospecting near the Arctic Circle. Rod’s willingness to go to the ends of the Earth (which happen to be in Canada) has earned him a collection of world-class specimens and breath-taking adventures. Future collectors visiting Canadian localities such as Rapid Creek, El Bonanza Mine, Society Girl, Emerald Lake, Grey Cloud Claim, Nanisivik, and Rock River have Rod to thank for helping to clear a path. Born with the “collector gene,” Rod was fortunate to have had parents who supported him when minerals first grabbed his attention in his adolescence. Following his heart, he earned a Bachelor’s degree in Geology from the University of Toronto. He and fellow student Helen Ohrt fell in love with field collecting and one another on their weekend prospecting trips. The two married and became part time mineral dealers. During those early years, Rod worked as a geologist while Helen completed her graduate degree. In 1975, Rod and a classmate began leading field trips; thus began his epic expeditions to the farthest reaches of Canada. By 1980, with Helen as his partner, Rod was a full-time mineral dealer. Fast forward through a lifetime of field experience to 2018, when Rod was awarded the American Mineral Heritage Award in recognition of his field-collecting achievements. We are pleased to welcome Rod Tyson to the podium to share the wonder, adventure, and minerals of the Yukon.

Joyce Engineering Technologist • Dealer • Musician Speaker (two presentations) The Cobalt-Gowganda Silver Mining Area Mont Saint-Hilaire – Great Minerals, Great People David K. Joyce’s life has largely been about getting minerals out of the ground. He became a mineral collector at the age of 12, eventually graduating from the Haileybury School of Mines. He worked for many years for ICI Explosives, traveling Canada, North America and eventually across the world and has taught explosive technology at the University of Toronto. David has been a mineral dealer for decades. He is a Fellow of the Canadian Institute of Mining (CIM), recipient of CIM Past Presidents’ Memorial Medal, and twice Member-of-the-Year of the Walker Mineralogical Club. He is a talented musician and songwriter. His musical mineral collecting and mining musings are captured on a CD entitled “Nuggets and High Grade.” His sing-alongs are staples of late- night gatherings of fellow collectors. Reflecting his diverse experience and interests, David will give two presentations at this year’s show: one on the people who have made the unique deposit at Mont-Saint-Hilaire in Quebec famous, and the other on history, geology, and minerals of the Cobalt-Gowganda Silver Mining Area. The discovery of high-grade silver mineralization in 1903 at the latter led to a mining boom seldom seen in North America before or since. The discovery resulted in the development of 100 or so mines that produced over 600 million troy ounces of silver over the years. The wealth generated from this production financed the formation of many mining and exploration companies, which in turn resulted in more discoveries of economic minerals all over Canada and the world. Mont Saint-Hilaire (MSH) is one of the premier mineral localities of the world.
